% Rice, the world's No. 1 grain in productiveness
and the basic food of a good part of the world is not
too popular in the United States. Only eight of the
48 states eat much rice and these states are in the
South where the grain is grown. Nevertheless, prior
to the War, some fourteen million barrels of rice
were marketed from U. S. production and nine mil
lion barrels were consumed in this country. Present
day figures show a U. S. production of nearly twenty
million barrels with domestic consumption amount
ing to nearly thirteen million barrels.
.
Gordon Harwell, of Houston, Texas (now presi
dent ofConverted Rice, Inc.), set himself the task of improving rice for more popular acceptance through out this country. In order to do this, it was recog nized that it would be necessary to overcome some of the more unfavorable characteristics of rice such as the tendency to become gummy in cooking. Lack of uniformity in color, flavor, and vitamin content were also noted as disadvantages in addition to the susceptibility of rice to weevil attack. After about ten years of experimentation and study, a process in use in London, England, came to his attention. Following some investigation, a license was obtained
9
CRIMDEBN00000243
CRIMDEBN00000244
and immediately afterwards he started to build a manufacturing> plant in Houston, Texas. Ten months later, October, 1942, the first shipment of Converted Rice was loaded.
It was thus that Converted Rice, Inc. of Houston, Texas, in the best tradition of American business, started a new enterprise in the interest of.marked improvements in one of the world's basic foods. The new rice is translucent in color, impervious to weevils, of optimum vitamin content, and no longer has a tendency to become sticky in cooking.
The new process soon came to the attention of the Army Quartermaster Corps. As untold millions of dollars' worth of rice have been lost annually to weevil attack, especially during warm months, the Quartermaster Corps was principally interested in
the keeping qualities of the new rice. This one im-
portant characteristic, together with the other
advantages, resulted in the total output of the plant
going to the Armed Forces during the war years. A
large percentage still goes to them, but packages are
finding their way to grocers' shelves in increasing
quantities.
.
The Houston firm's process consists of several
steps. From an overhead hopper, rice is charged
into the steeping tank. Then a vacuum of 13 to 17
in. Hg,' referred to a 30 in. barometer, is established
by means of two Elliott single-stage ejectors. Hot
water is then injected into the steeping tank until
the water is above the rice. Air pressure is then
applied in the vapor space above the hot water level
to force water into each rice kernel. The water
carries with it into the grain a high percentage of

in usual milling methods. Following some ten
minutes under this condition, the air and water are
i released. The wet rice is then dropped through a
| large valve in the bottom of the steeping tank to a
; rotating steamer immediately below. In the steamer
the starches are gelatinized and flavor and minerals
' are heat-sealed into the grains. After some five
minutes under a pressure of approximately 12 psig,
the steam is released to atmosphere, and the vapor
line from the steamer is switched to an Elliott
barometric condenser and two-stage ejector. These
establish a vacuum of 28 in. Hg referred, in some
25 to 28 minutes. After establishing this vacuum,
steam is admitted to tubes inside the steamer to
further dehydrate the rice. Approximately two to
: two-and-one-half hours pre required to complete
. the process. '
The rice is then dried and milled, including a
polishing operation. The hard, highly polished sur
face achieved makes the grain impervious to weevil
attack, a very desirable improvement.

# This year marked the 50th anniversary of the Hope Natural Gas Company, whose headquarters are located in Clarksburg, W.Va. Very appropriately: the Company has just completed an expansion program in which its plant facilities have been more than doubled within the past eight years. Beginning 50 years ago with a small number of oil and gas leases in Marshall and Wetzel Counties, five or six gas wells, several miles of line and a few customers, the Company now has a plant investment of more than $100,000,000,- owns gas leases totaling 1,234,951 acres, operates 3301 active gas wells in 35 counties of West Virginia, operates 53 compressing stations with a total capacity of 135,625 hp, owns 5509 mi. of pipe line, produces approximately 40,000,000 gal of gasoline and by-products yearly, has 3026 mi. of telephone wire, 27 radio cars, and seven land stations, uses 204 trucks and 128 cars, purchases gas under 391 gas purchase contracts. It employs 2220 people.

boiler fuel to coal. For a while coal was obtained on
i the Hastings property but later had to be purchased.
In 1930 a completely new boiler house was built
i containingthree stoker-fired 80,000-lb-per-hrboilers,
! with all necessary boiler auxiliaries.
I In 1926 a No. 2 compressor plant was built a
' quarter of a mile away from the No. 1 station. In
this plant was installed four 2000-hp steam-engine-
driven compressors as well as four 25,000-lb-per-hr
steam boilers. The No. 2 plant had its own electric
and water supply and was intended to be an inde
pendent plant, although discharging gas to the same
pipe line system as No. 1 plant.
'
, In 1940 a new 100,000 Ib-per-hr powdered coal
boiler was installed in No. 1 plant.
In 1944 it was decided to supply New York State
NaturalGas Company directly fromHastings by lay
ing a high-pressure 12-in. pipe line from Hastings to
I Clarion County, Pa., a distance of 144 miles. This
j line was designed for 1300-psi operating pressure
i and two 2000-hp steam-engine compressors were
1 added to the No. 2 plant along with another 80,000-
lb-per-hr powdered-coal-fired boiler.
In 1946 a new 1300-psi line was laid to-the East
Ohio Gas Company.
! Completely new compressor and electric generat-
. ing stations at Plant No. 1 have recently been put
into operation. Designed by the Company's engi-
> neering department, to the exact requirements of
{ the stations, these plants incorporate excellent
equipment, well arranged, and painted in the latest
i dynamic color scheme, on the theory that operat
ing personnel will be inspired to take best care of
such equipment. The No. 1 compressor plant now
consists of seven 2000-hp, two 800-hp, and one
500-hp engines, making a total of 16,100 hp. No. 2
plant contains eight 2000-hp engines, making a
total compressor capacity of 32,100 hp. To supply-
steam for these engines a new 125,000-lb-per-hr boiler was added to the No. 1 plant and an 80,000lb-per-hr boiler to the No. 2 plant. New water cool ing towers were added, additions made to the boiler water treating plant, and many other improvements.
- To serve the electrical requirements of both stations a new electric generating plant was built. The ate chosen for it was formerly occupied by the boiler house. The concrete foundations of the old boilers had to be blasted out before construction could begin. The three Elliott 1500-kw turbinegenerator units are supplied with steam at 175 psi from the boiler house approximately 100 ft away. There is a bleeder connection on each turbine to supply low-pressure heating steam when needed. The turbines are served by three Elliott 2500-sq ft condensers and auxiliary equipment. Circulating water pumps are 3000 gpm each and discharge into a header permitting any pump to service any con denser. The electricity which is generated in the plant at 2400 volts, 3 phase, 60 cycles, is distributed at this voltage and, through transformers, at 480 volts, to a load consisting of motor-driven auxiliaries in the boiler house and in both compressor stations, various large motors, such as five 200-hp motors inthe water pumpring house, the motors in the gasoline plant and the lighting load.
The generator' building, 78 ft x 44 ft, is of rigid frame construction with brick facing and glazed tile interior up to the second floor window sills, with transite siding above. The building is designed so that it can be extended and an additional tur-
I 19
CRIMDEBN00000253
bine-generator unit may be installed when needed. As a part of the same program, the natural
gasoline plant on the outlet of the station was com pletely rebuilt. It is now an ultramodern gasoline and petroleum by-products plant, capable of turning out under peak load flows of over 150,000 gal per day of gasoline, butane, propane, and ethane. At the same time, the dehydration plant on the outlet of the gasoline plant was enlarged so that all gas going into the distribution lines is thoroughly dry.
It has been necessary to build a complete com munity to house part of the men who run the plant, ' as there is no large town within 20 miles of Hastings. So with the plant itself has grown up a community of about 67 houses, complete with its own water, gas, electric, ice, and sewage systems. Normal oper ations at Hastings regularly require about 175 men. During the recent construction work a camp housed more than 200 employees.
The final result of all this expansion program is a station almost completely rebuilt since 1940, with No. 1 plant discharging into the older pipe line system at 400 psi pressure and No. 2 plant dis charging into the new high-pressure line system at 1300 psi. In spite of this increase the new plant has fewer buildings than the old plant and from all angles is more modern and efficient.
In the boiler plane are. three Elliott 375,000-lb-perhr deaerating feedwater heaters. These units were
installed- at various dines during the expansion of the boiler plant, the latest orie.going in last year., )
20

The photographs show how an Elliott 100,000Ib-per-hr horizontal deaerating feedwater heater was manipulated in through a window to replace an older heater in the plant of the Western Massachu-, setts Electric Company, Pittsfield, Mass.
This company, organized in 1906, operated for a few years as a Diesel plant. In 1910 they installed two boilers and a 750-kw turbine-generator unit. In 1913, a 1000-kw turbine-generator unit was added, and in 1917 a 2500-kw unit and additional steam generating capacity. In 1922, a 5000-kw condensing turbine-generator was added and is still available for service to supplement power genera tion capacity at other stations in the system.
The Pittsfield Electric Company combined with other companies in Western Massachusetts in 1923 and
became known as the Pittsfield Elec tric Company Division of Western Massachusetts Companies. Later,
all divisions were combined into one company, presently known as Western Massachusetts Elec
tric Company. While the 5000-kw turbine
is only operated during peak load or emergency periods, the station is used for sup
plying heating steam to the business section of Pitts field. The Elliott deaerat
ing heater, therefore, is constantly in service.

Showing arrangement of the vertical pumps in the Metzger Lake Station.
Since 1832, when a post office was first estab lished in Lima, Ohio, this community has shown steady, persistent growth. Water supply adequate to meet the needs of a growing city has been a prob' Iem and at times supply has lagged behind demand.
Serious water shortages, recorded at six different times, have served to spur development of addi tional facilities. The last such occasion occured in January 1945, when, for a period of several weeks the reservoirs were practically empty and a re stricted supply was drawn from industrial wells through emergency connections, and from an abandoned stone quarry which happened to be full of water. The emergency bad arisen as the result of long continued drought, coupled with greatly in creased demand of industries in war production.
Outcome of this latest emergency was the con struction of a new storage reservoir and pumping station, practically doubling the existing capacity.
Lima obtains its water supply from the Ottawa River, a small stream with very small flow through most of the year, but which carries considerable water in wet seasons. Water is pumped from the river into upground storage reservoirs, and with-
drawn therefrom for treatment and distribution as
needed. Three principal reservoirs now are in use.
The first, Lima Lake, was constructed in 1902 and
has a capacity of 430 million gal. The second. Lost
Creek Reservoir, holds about 860 million ga]., and
dates from 1920. The newest unit was put into
service in the fall of 1947. It has been named
Metzger Lake in honor of the late William E.
Metzger, Jr., a hero of World War II, who was
awarded the Congressional-Medal of Honor during
the campaign in Italy. Capacity of Metzger Lake
is 1200 million gal.
Each reservoir is served by a pumping station.
The largest of these is, of course, the Metzger Lake
Station, built to serve the new reservoir. Metzger
Lake Station is equipped with three vertical centrif-
. ugal pumps, each with capacity of 25 mgd against
a total head of 70 ft, and each driven by an Elliott
3S0-hp synchronous motor.
The pumps discharge through individual venturi
meters into a 54-in. steel cylinder reinforced con
crete force main leading to the reservoir about 3000
ft distant. Pump controls are either manual or
automatic in relation to the elevation of water in
the pump suction well and the reservoir. Automatic
cone valves, in the discharge piping of each pump,
open when the pump comes up to speed after start
ing, and, through electrical interlocks, close before
current to the motor is interrupted on the stopping
cycle. Speed of opening and closing is regulated to
prevent building up excessive surge pressures.
Pumps are protected from entrance of debris by
two mechanically cleaned bar screens. Screen rakes
may be operated manually, or automatically by
time clock, with an over-riding control actuated by
head loss through the screen.
-'
Final tests were conducted on the completed
installation in January of this year and the opera
tion of the system was found to be entirely satis
factory. The 25-mgd Delaval pumps delivered from
26.4 mgd to 30.0 mgd at 66-ft total head.
-
The rate of pumping provided will .fill the new
1200-mg reservoir in about two weeks, and the
three reservoirs are so interconnected that the two
older reservoirs may be filled from this new source.
Should either of the old pump stations fail during
the short period of draw-off from the Ottawa River,
.the new pumping station can be used.
The complete program was under the supervision
of E. E. Smith, superintendent of the Lima Water
and Sewerage Departments. Jones and Henry Co.,
engineers, of Toledo, Ohio, prepared the plans and
specifications and supervised the construction:

New coke ovens at the Lorain, Ohio, works of National Tube Company have boosted output by 800,000 net tons annual capacity, bringing the total capacity of the works to 1,850,000 net tons.
The new installation consists of three batteries, each of 59 regenerated ovens, designed for firing with coke oven gas having a calorific value of 500 to 550 Btu per cu ft. Later they may be underfired with blast furnace gas by the installation of suitable auxiliary equipment. Provision has been made for the construction of three additional similar batteries of ovens should conditions warrant.
Coke handling equipment consists of a 240-foot wharf, conveyors from the new wharf and two ex isting wharfs to a trunk line conveyor, coke scalp ing, crushing, screening and rail loading facilities, together with car haulage, sized coke surge bins, filling conveyors, motor-operated bin gates for un loading trucks, and motor-operated bin gates for the delivery of furnace and domestic coke to a pro
posed conveyor system to the blast furnace bins. Four Elliott turbine-driven exhausters serve the
coke ovens at Lorain. These units are rated 29,750 - cfm each, with pressure rise from minus 14 in. of
water to plus 81 in. ofwater. Elliott 600-hp turbines ' drive each blower at 5000 rpm. '
The gases generated in the coke ovens are re moved by these centrifugal exhausters which, by automatic governor control, maintain a vacuum of 14 in. of water in the ovens. Discharging at a pres sure of 81 in. water, they force the gas through the by-product recovery plant and into the main gas holder. Steam turbine drive is used in order to obtain best economy for variable load operation. An important advantage of the centrifugal type of exhauster is its ability to remove a good portion of the tar contained in the gas. The tar is thrown out ward by centrifugal force onto the casing and is then drawn off at the bottom. The heat of compression
keeps the tar in liquid form.

# The latest addition to the Diesel generating plant at Grand Haven, Mich., was put into oper ation recently. It marks the sixth Diesel unit in the plant, and the fifth extension since the first two 800-kw units were started in 1931. The plant, with its total of 13,300 installed horsepower, is one of the largest Diesel generating plants in the country.
A manufacturing and resort town on Lake Michigan where Grand River enters it, Grand Haven has generated its own power since 1896. The original steam plant grew until it attained 3000-kw capacity in 1928. Increased loads and high production costs led in 1929 to construction of a Diesel power plant.
In 1931, two 1140-hp Baldwin DeLaVergne four cycle engines, driving Elliott 800-kw generators,
! .
were installed, followed three years later by a third
unit, exactly duplicating the first two units. In 1937
the building was extended and a 2250-hp Nordberg
two-cycle Diesel driving a 1600-kw Elliott genera
tor was added. In 1941 a Nordberg two-cycle, 2715
kw engine-generator was placed in the building.
All this time the boiler plant with the 3000-kw
of turbine capacity had been maintained as a stand
by, since firm capacity of the Diesel units (full load
with largest unit out) was inadequate to meet peak
demand. When one Diesel was out for inspection or
overhauling, steam plant boilers were held on bank.
This was expensive in fuel and also labor,'as Diesel
operators cannot readily attend the steam plant.
In 1946 an exhaustive study was made of the
problem of meeting current and future loads.
So another addition was made to the station
building large enough to house two more units of
the same size and type as the fifth unit, installed
in 1941. The riew unit is a Nordberg 21J^ x 31 in.,
225-rpm, air injection, two-cycle Nordberg engine,
direct-connected to an Elliott 3390-kva, 7200 volt,
3-phase, 60-cycle generator.
The Grand Haven power system's own organi
zation handled all engineering and construction of
the recent extension. .
.
In the foreground is the new Elliott 2715-kw generator
with belted exciter. Immediately behind this new unit are the three Elliott 800-kw generators serving engines instal
led in 1931' and 1934. In the extreme background, not shown in the picture, is another Elliott 1600-kw generator.

Last summer, the twelfth beet sugar factory of the Holly Sugar Corporation, second largest beet sugar producer in the United States, went into operation in the Imperial Valley in southernmost California. This new plant was of such interest to the industry that the magazine "Sugar," in its September issue, carried a nine-page feature article on it, the article being illustrated with 35 photo graphs. The plant was also featured on the front cover of this magazine. The fine new factory, with a rated daily slicing capacity of 2700 tons of beets, actually reached slightly in excess of 3000 tons, resulting in a daily sugar production of 800,000 lb, has been named in honor of the late A. E. Carlton, formerly president of the Holly Sugar Corporation.
The location of the plant in the Imperial Valley gives rise to problems and advantages not found elsewhere in the world. Carlton is the only beet sugar factory in the world to be located below sea
level. In fact, the lettering "Sea Level" is carried about 90 ft up on the exterior of the bulk sugar storage bins where they face U. S. Highway 99.
The Imperial Valley is proving one of the most fertile and profitable agricultural areas in the United States. With a total rainfall in 1947 of only 0.87 in., the valley depends entirely on irrigation water supplied from the Colorado River by means of the Imperial Dam and the All-American Canal. Some 370,000 acres are now under cultivation for all crops. Growers under contract to Holly had 29,000 acres of beets this year, and Carlton sliced beets from over 12,000 of these acres.
The Imperial Valley is the bed of the ancient Lake Coahuila, which was fed by the mud-laden waters of the Colorado River. The lake slowly decreased in size until it disappeared. Today, how ever, the shore line of old Lake Coahuila is still visible at several different locations along the edge of the valley. The Salton Sea was formed by a flood of the Colorado River in 1906. The New River was also formed at that time, in addition to the existing Alamo River. Bed rock is covered by an enormous layer- of silt and sand, which in some places is 2000 ft thick. The valley is seismically active, earth tremors are not uncommon, and at least fourteen faults extend through the valley--two of them within a mile of the factory. So "earthquake" con struction, in conformity with the. Pacific Coast Uniform Building Code, was used in the plant's con struction. Concrete piling was used under all loaded

parts of the factory--more than 1500 pies were
driven in all, to a depth of 50 feet.
'
The factory buildings have an elaborate air cool
ing and ventilating system--330,000 cfm of water-
washed air are circulated through the plant for
cooling. The low humidity in the valley - allows
sufficient temperature drop with such a system so
that the temperature within the factory is quite
moderate. Heavy insulation on all hot juice and
steam lines and hot equipment reduces radiation.
Steam at the Carlton plant is generated at 410
psi, 575 F in a single oil-fired boiler! This boiler has
a rating of 150,000 lb steam per hour continuously,
or 180,000 lb per hour for a four-hour period. At
3,000 tons per day slicing rate, steam requirements
are 146,000 lb per hr. Stack gases are used to
partially dry the pulp in the pulp dryer. All high-
pressure steam is confined to the power house. Steam
used for exhaust make-up is reduced to 100 psi and
desuperheated, and evaporator vapors only are
used for process heating and boiling. A 3000-kw
turbine-generator has sufficient reserve capacity
for future process installations.
As in all beet sugar plants, purification of the raw
juice is accomplished in a carbonation tank where
m-".k of lime is added. The lime is prepared by burn
ing lime rock and coke in a lime kiln which also produces carbon dioxide gas, which is bubbled through the mixture in order to make the lime in soluble. An Elliott turbine-driven, single-stage centrifugal blower is used to create the draft through the lime lain and to pump the carbon dioxide gas to the carbonation tanks. For this service a high-speed blower is particularly adapted.
The plant was designed by the engineering de-. partment of the Holly Sugar Corporation, and . was completely constructed under its supervision.
This sketch plan of the new Carlton Factory shows the extensiveness of the operation. This
extraordinary plant is located five miles south ofBrawley on U.S. High way 99, which is shown at the bottom of this sketch. The factory is surrounded by fields of
sugar beets. .

The plant of Mrs. Tucker's Foods Inc., at
Sherman, Texas, produces high-grade, uniform
quality margarine and vegetable shortening under
rigid standards of purity and quality. The motherly
face of the company's trade-mark "Mrs. Tucker''
is known throughout the Midwestern and South
western states where its Meadolake margarine and
Mrs. Tucker's shortening are distributed.
There is a never-ending routine of testing, in
specting and process-controlling in this modern
plant. From the time the crude vegetable oil, either
cotton seed or soybean, flows from the tank cars,
until the products are packaged, there is relentless
watchfulness at every step of the process.
The oil arrives in tank cars. It is first treated
The purpose of deodorization is to remove objec tionable odors, improve the keeping qualities of the oil, and lighten its natural color. Deodorization is made possible by the fact that neutral fat cannot be vaporized to any appreciable extent, but com ponents of oil which impart flavor and odor can be changed into vapors under high temperature and low absolute pressure, and can be removed from the oils as gases. Steam Sowing through the oil acts as a carrier to sweep vapors from the oil; it also ab sorbs part of the low absolute pressure, so that the absolute pressure of the oil vapor is lowered.
for deodorizing Margarine and Shortening
with an alkali to neutralize any undesirable natural adds that may be present. These adds are removed in the form of crude soap. The color of the oil is then lightened by contact with, a natural clay which absorb? the coloring matter. Hydrogenation then changes the liquid oil to a semisolid which is necessary to produce the finished product. Appropriate mixing is necessary after hardening in order to control firmness. Deodorization is the final step before packaging. This removes any ob jectionable flavor of the vegetable oils and leaves a bland product. At this point the fat is ready for chilling and packaging in the form of shortening or is mixed with milk solids and other ingredients for use as margarine. Both margarine and shortening are quickly chilled in refrigerating devices' similar to ice cream freezers and then packaged in sanitary containers. Margarine is at least 80 per cent fat and about 20 per cent milk solids, salt, and other ingredients. Shortening is 100 per cent fat.
A battery of three Elliott boosters (or first ejector stages) which serve the deodorizers la the plant of Mrs. Tucker's Foods, Inc., Sherman, Texas. The boosters are connected to a manifold through shut-off valves. The second and
third ejector stages may be seen at the lower right.
preventing vapors returning to the liquid phase. In the deodorization process the oil is heated to a
high temperature to promote active vaporization of the components which cause unpleasant odors and flavors. Low absolute pressure works with high temperature in this process. The heating is ac complished by circulating the heated vapors of a chemical known as "Dowthenn" through closed coils that are in contact with the oil in the still.
Elliott three-stage ejectors maintain the low absolute pressure required for the deodorization process. These ejectors handle both the undesirable oil vapors flashed from the oil and the steam ad mitted to the deodorizer. These gases are handled at around 4S0 F without the slightest difficulty.
