NEW MARKETS . . . NEW OPPORTUNITIES FOR LEAD On the surface, it may seem strange that the lead industry, which for the last several years has been enjoying a reassuring period of increased con sumption, should be seeking additional markets. Vet, that's exactly what's hap pening. And the search is likely to result in new opportunities for marketing of lead. -- The reason for the current stepped- up market development activities stems from lead's heavy dependence on a sin gle market--the automotive industry. In this prime sales area, lead is being phased out of gasoline in the United States. As a result, the lead industry must seek new markets for the lead formerly used in antiknock additives. There is also the need to create new markets for the lead used in automobile storage batteries as new competitive storage battery systems emerge. In the U.S., antiknock additives required 194.000 short tons and storage batteries 960,000 short tons out of a grand total of 1,547.000 short tons of lead con sumed in 1978. The logical way for the lead industry to overcome its present market de pendence on gasoline-powered automo biles is to develop new uses and markets for batteries. A most promising new application for batteries is to power what many people believe to be the next generation of vehicles--electric cars. opportunities exist for large numbers of The lead industry and the federal gov batteries for load-leveling purposes. ernment have committed millions of Another exciting area which should dollars for research and development of provide a potential growth market for improved lead batteries to power electric vehicles and hybrid vehicles, the latter powered by batteries and another power lead batteries is the solar electric energy industry. As this industry grows there could be a large-scale need for lead source. Many thousands of these vehi cles are expected to be in use on the batteries to store solar generated elec tric power in remote locations and even nation s streets and highways in the next five years. tually for use in homes arid commercial establishments. The lead industry also is taking a Last, but not least, lead with its hard look at other battery markets that superb sound-barrier characteristics, might be expanded. One such market is should find w ider use in reducing noise in the electric utility industry where pollution. hile the problem of the heavy de pendence on the automotive market should not be underestimated, recent activities by the lead industry show that it is determined to solve its problems by finding new and expanded outlets for this important, strategic metal.

Readings were taken using a sound level meter and graphic level recorder. The meter was positioned in the machine shop (12 feet from the noise source) and readings were taken--first with the curtains open and then with the curtains closed. The reductions achieved through the use of the noise attenuating/absorb ing curtains was 10-12 dBA. According to Frank Gagne, the instal lation of the acoustical curtains `"has im proved employee morale, eliminated the need for hearing protection in adjacent areas, and. hopefully, will increase pro duction, reduce fatigue and errors in the machine shop and wing final as sembly areas."

Inc., uses electric fork lift trucks to handle 170-lb. blocks of frozen orange juice in 14-degree below zero conditions. The trucks work 15 to 18 hours a day, up to seven days a week. During the July to December harvest, juice for use during the summer and fall months goes into a bulk freezing system. Frozen blocks of juice are hand stacked on 36-in. by 72-in. pallets, 26 blocks to a pallet, covered with poly ethylene, strapped and conveyed by 5000-lb. electrics into cold storage rooms. In the retrieval process, the bat tery-powered trucks move the pallet loads into ambient temperature where the load is put through a crusher and a heat exchanger that brings it up to 55 degrees. The block then goes through the process that produces single-strength orange juice. R.T. French is using battery-powered trucks to meet the three-pronged require ment of 16-hour work days, reliabilitv and non-pollution in its food-processing Stacility at Souderion, Pa. Here, mustard produced in the morning is shipped in the afternoon, and the afternoon's pro duction leaves the plant the next morn ing. Add to this the plant's output of sauces, spices, gravies and pet food, and the need for reliable material handling equipment is apparent. And with food as the end product, the fume-free opera tion of the electrics is essential. Seven battery-powered fork lifts carry 75 percent of the goods. The trucks do not operate continuously during the plant's two eight-hour shifts, but rather in spurts, coping with two-ton pallet loads.

LIA26857 5 128-year-old terne original terne-coated steel roofing to be as good as when it was installed, some doesn't show its age 128 years ago. Terne-coated steel combines the strength of steel with lead's superb corro sion resistance, solderability and paint- ability. Terne is generally mild steel coated with a lead alloy containing When States Roofing & Metal Co. re cently started to restore the dome, about 6 percent tin. The coating is applied to the steel based on the vertical supporting surfaces and circumw eight of the tin/lead alloy per square ferential walkway atop the Alabama foot. For roofing purposes, a 40-lb. coat State Capitol they found much of the ing is usually specified. fflf: hit. Alabama's State Capitol in Montgomery is one ot the most impressive in the country. Much of the terne-coated steel on dome, promenade and supporting drum remains in excellent condition today, 128 years after its installation. Scaffolding encircles Alabama State Capitol dome to enable rooters to partially replace 128-year-old terne metal. Circular drum (Below) which constitutes base ot Capitol dome, also received new "skin" of terne-coated steel. 6 Since the lead coating on the steel not all that thick, periodic paintin * required for protective purposes r B sequently the terne metal roof on th State Capitol in Montgomery, Ala h a been subjected to numerous coats paint in its 128-year existence. Then few years ago one painting contractor sandblasted a number of areas to remove the old paint. This also removed th terne coating and areas of rust devei oped. However, the terne in other areas retained its excellent condition. Because of terne's remarkable service record, and because state officials wanted to restore the Capitol building to its original beauty, States Roofing applied a similar flat-lock seam roof on the dome as well as on the circular drum (or sup. port structure) below the promenade. In addition, terne-coated stainless steel was used in many of the flashing areas be tween the dome and drum section. The terne coating for the stainless supplied by Follansbee Steel Corp,, Fob lansbee, W.Va., is composed of an 80 percent lead and 20 percent tin alloy. The Type 304 chrome-nickel stainless steel used is produced in a condition known as "dead soft." This makes it easy to form with no springback, an advantage in fabricating such architec tural components as flashing and fascias. And, unlike terne-coated carbon steel, the TCS does not require painting. This is a benefit in hard-to-reach areas. The reroofing work on the dome and related areas w as a hazardous undertak ing for States Roofing. A wood scaffold ing had to be erected around the entire dome to allow access and safe working conditions for the removal of old ma terials and preparations of the surfaces for restoration. The work on the dome area of the State Capitol was the first step in a complete restoration of the structure, now designated as a national historical landmark. Well-known restoration ar chitect Nicholas H. Holmes Jr., FA1A, is in charge of the project. Some of our most distinguished ar chitects have, in their time, specified terne for finishing building exteriors. Frank Lloyd Wright, for one, observed that he "found terne superior to other roofing metals in economy, color ad herence, heat reflection, permanence, workability and low coefficient of ex pansion." In addition to the advantages specified by Wright, terne is a highly ductile material which needs no pretreatment for soldering and is just about the lightest satisfactory roofing metal known. Wave soldering of motor armatures provides increased productivity and improved quality Schematic shows position ot commutator armature in half-bearings and its relation to the rotator and solder wave.

As armatures are conveyed, caterpillar-treaded belt (arrow) continually and uniformly rotates them. 600 to 800 armatures per hour. Automatic wave soldering is also being substituted for the dip method at Brevel Motors in Carlstadt, N.J., where squirrel cage armatures are soldered and assembled for use in fractional hp motors. In this case, however, the sys tem operates on a carousel type, adjusta ble speed conveyor, and a Hat wave is used to solder the copper rods of the armatures. An operator places the assembly to be soldered on overhanging pins. The assembly is then automatically con veyed horizontally through fluxing, soldering, spinning, cooling, cleaning and unloading stations. The depth of solder immersion is precisely controlled to prevent the solder from entering the center hole of the armature. This elim inates hole reaming which was often necessary when the armatures were dip soldered. Brevel has reportedly achieved production rates of up to 1800 arma tures an hour with this method.

As its name implies, the structure connects the New York City borough of Queens with Man hattan. Spanning the City's East River, the Queensboro Bridge passes -over Roose velt Island, situated in the middle of the River. When it was completed in 1909 the bridge was the largest, longest and heaviest cantilevered bridge ever built, and it remains one of the largest of its type today. Originally designed to carry pedestrians and the Second Avenue ele vated subway as well as trolley cars-- both transportation systems are no lon ger in use--the bridge carries 144,000 vehicles per 24-hour period, making it one of the busiest of the City's no-toll spans. The Bridge is currently being re painted, a task that will take two years and 40 full-time painters. Since the Queensboro has been designated as a New York City Landmark, the final color scheme had to be coordinated between the City's Landmark Commission and the Department of Transportation (DOT). The structure's steelwork will be a tan while its four towers will be painted brown. A brown horizontal stripe will also adorn the bridge. About 64,000 gallons of lead-based paint will be used in two coats to cover the bridge. A key element of the primer is the basic lead silico chromate anti corrosive weather-resistant protective pigment. It is the lead pigment that pro vides a durable and compatible paint that offers superior corrosion protection. DOT reports that lead-based paints have been used on New York City bridges since they were constructed be. cause these paints provide the durability and weatherability required for steel structures. Following the application of the primer an alkyd finish or top coat, also containing the basic lead silico chromate, will be applied. Prior to painting, old paint, rust and dirt had to be removed. Power-driven chippers and wire brushes were used to remove rust and rust scale. Hand chip pers, scrapers and wire brushes were utilized to remove pitted paint, dirt, cement stains and deposits, and oil and grease which had accumulated over the vears. Inaccessible areas, large accumu lations of oil. rust and grease around expansion joints and all other areas were cleaned by a brush-off blast cleaning method. Lead-based paint is applied to steel structure ot Queensboro Bridge.

Filled with France over 137 hours later. 160,000 cu. ft. of helium, the balloon Maxie Anderson and Ben Abruzzo, was 11 stories high.

If you are not claustrophobic, have $12,000 and a strong desire to ex plore the ocean depths, a personal oneman submarine could be the answer. Up in Warren, Maine, George Kittredge, a retired L .S. Navy Captain, has been building these submarines off and on for the last ten years. Kittredge, who is also responsible for the vessel's de sign, calls it "the most maneuverable small submarine available." The basic model is 12-ft. long, weighs about 2,500lb., and can submerge to depths of up to 250-ft. A more elaborate version, which sells for $16,000, can dive 350-ft. Power for both models is derived from 12-volt lead batteries. According to Kit tredge, while heavier deep discharge bat teries would be more efficient, they are less desirable because of the sub's small size. The smaller vessel is equipped with three 12-volt batteries, while the larger craft has eight batteries. In addition, both submarines employ lead weights for ballast purposes. Submerging and surfacing of the sub marine are controlled by three tanks that are filled with water or air to de scend or rise. The batteries power two rotating thruster motors which allow the vessel to move in various directions at speeds of two to four miles an hour. Air supply is replenished by surfacing every hour or so. Important safety features have been built into the submarine in the event that a problem develops underwater. Filling of any of the vessel's three tanks with air would cause it to surface. Fail ing that, 190-lb. of lead weights can be released to make it float to the surface. If the craft is entangled and unable to surface, the operator can open the hatch and escape with scuba gear, including an emergency air tank, which is part of the sub's standard equipment. Ll*268fc5 Beveled glass--A new idea from an ancient art Leaded and hand-beveled glass door and side panels create flawless prism effect and add distinctive look to a home. The ancient art of stained glass has been updated through the use of According to the company, the in creased interest in beveled glass is due beveled glass arranged in a variety of to the fact that today people want the designs, all joined by lead. The shaped look of handcrafted objects rather than glass pieces are joined using lead cames, the artificial look of many materials that or H-shaped strips, with each joint over currently are found in homes and offices. lapping the glass and soldered on both Beveled glass is hand-set in much the sides of the panel. same manner as stained glass.

The bevels create prisms so tables and architectural accents. that light refraction creates eye appeal rather than color, as in stained All beveling is done by hand, and number of time-consuming steps required for the beveling operation. After the glass sheets are cut various shapes and hand-beveled, they are laid on a piece of paper that serve, as the pattern for the design. The ph**, are assembled somewhat in the sam, manner as a jigsaw puzzle. One section becomes the foundation for another section. After the beveled glass segments have been placed on the pattern, the individ ual pieces are joined by lead earning The earning forms the channel for the glass in much the same manner as s window frame holds glass. When all the pieces have been fitted the lead cames are soldered to tie the joints together. The completed piece is then put into a temporary frame, ready for shipping. At Beveled Glass Industries, more than 500 specially-trained artisans work together, thus increasing productivity. Each worker is responsible for com. pleting a separate operation. The operation has been designed to save time and effort. For example, it has been estimated that if one man were to create a 22-l/g-in. x 66-14-in. door piece from beginning to end, it would take approximately three weeks to complete. At Beveled Glass, the mass production technique accomplishes the task quickly and efficiently in such a manner that many pieces can be finished in one day. Encapsulated lead improves fishing net performance The use of a lead-cored nylon yarn has significantly improved the perform ance of Japanese fishing nets. The new yarn provides the heaviness, softness and water resistance required for effi cient net operation. In order to snare fish effectively, a net should hang as deeply as possible in the water, and show minimal change in angle with tide and current. This is usually accomplished with the use of weights. However, this makes the nets difficult to manipulate and the weights are often lost. And since the introduc tion of lighter plastic nets, the problem of maintaining a suitable fishing angle has increased. One Japanese company, Mitsui Mining & Smelting, discovered that net yarn comppsed of a lead core plastic monofilament would achieve the desired effec Lead-cored nylon yarn has improved Japanese fishing net performance. tiveness. The monofilament is produced by simultaneously extruding nylon and molten lead alloy through a spinning equipment nozzle. The extruded product is then drawn to produce the final con figuration shown in the accompanying diagram. The lead alloy segments are enclosed in a continuous nylon sheath with vacuum spaces in between. These spaces are formed between the lead alloy segments during the drawing process. Dr. Y. Yamanouchi, who heads Mit sui's research activities, reports that successful tests were conducted with set nets made of the new material. These nets are anchored in place in relatively shallow water (about 30 meters). Ac cording to Yamanouchi, the new nets trapped up to eight times as many fish as the conventional type. 14 The Lead Industries Association is a non-profit trade association a representing the lead industry in the United States and Canada.
