This molten lead is then run through the nozzle. /^T^This nozzle ie solid so as to retain the heat. The lead flowing through an opening of about in diameter through the oenter. At the * orifioe it is enveloped by a jet of slightly super heated steam which escapes 'ooSpletely surrounding the stream of lead. This atomizer converts it into a fine metallic lead dust. It is then conveyed out of this apparatus and put into cars containing about 4500#. These oars are taken up to the third floor where the entire contents is dumped as one charge into the corroding cylin der^ which cylinders are made of wood about 8* in diameter and 12* long placed so as to rotate slowly. Weak aoetic aoid ia added and to thia charge is added 40 gallons of water eaoh day for the first four or five days and then 65 gallons of water per day dur ing the balanoe of the time while the oorroding is going on. This corrosion requires from 12 to 14 days. COg gas is delivered to these cylinders through a pipe extending through an opening at the oenter at the rate of about 225 cu. ft. per minute. At the end of 12 or 14 days all of the metallic lead has been converted into white lead and then lies as a white paste in the cylinders. The man holes in the oylinders are opened and allowed to stand for 24 hours or so at which time a man gets into the cylinder and shovels out the material through a hole in the bottom. It is then washed to separate from it any particles of lead which are unoorroded which are gathered by a chain conveyor made of a sprocket ohain with cross pieces of wood whiah travel along the bottom of thia washing tank in a trough and deliver these particles through an opening higher up in the trbugh. The corroded lead is then drawn off into other tanka, allowed to settle, water siphoned off the paste then put into steam jaakstsd drying pans where it is dried for a period of five or six days. It is then pulverized, paoked in barrels in the dry state or taken before being pulverized and ground with oil. In grinding BO# of raw linseed oil is mixed with 1000# of dry lead in a chaser. After it is smooth it is conveyed from the ohaser into mixers set in the floor much the same as the 30* mixers used in our factories. Material is delivered to the mixers through a vertical worm conveyor which delivers the material to the mills as fast as it can be taken. The millB are much the same as our 30" paste mills except they are not water oooled and the stones are very much rougher. The lead does not heat up very much and seldom attains a temperature of more than 140 degrees F. From the mills it is conveyed in a water jacketed con veyor to the filling hopper. At the bottom of this filling hopper la a short con veyor about 2' long which conveys it to the kegs where it ia filled through a spout which fits into a 2* bung hole. This is firmly pressed against this hole thus filling it under pressure to make it level up inside of the keg to allow for the dis placement of air a small ventilating hole ia put into the head of the keg and after ward plugged up with a wooden ping. The label is pasted over this bung and the kegs are finished with a oheap finishing varnish. 0007-SWP-i RIBBON METALS A process by which ribbons of various metals can be manufactured very cheaply has been devised by Messrs. Strange & Graham, Research Chemists and Chemical Engineers, of 7 Staple Inn, Holbom, W.C., the Patentees, with the result that any of the more easily melted metals can be obtained as ribbons of extreme fineness, which, owing to the large surface-area they, possess, are eminently suitable for many chemical and mechanical operations. The process is an exceedingly simple one. The molten metal is caused to flow through one or more nozsles in a thin stream on to the periphery of a rapidly rotating water-cooled dram. The metal' solidifies immediately, and is thrown off from the surface of the drum in the form of a continuous and uniform ribbon. The width of the ribbon is dependent upon the diameter of the nozzle, and the thicfcness varies inversely as the speed of rotation of the drum. It is quite a simple matter to. obtain metal of a fineness of inch, and half a mile of ribbon can readily be obtained from each nozzle per minute. There is no difficulty in increasing the number of nozzles in use on one drum, and thus the output is proportionately increased with scarcely any additional expense. The cost of the plant is small, and it is calculated that Ribbon Lead can be prepared at a cost of from as.6d.to 3s. 6i. per ton. The cost of preparing strip lead or lead shavings as now made by some cutting operation for jointing purposes )Vgreatly in excess of this, and the material when prepared is hardened by the action of the cutting tool used, and is useless for white-lead making and not so suitable lor jointing. The process has already been successfully applied to the manufacture of ribbons of lead, zinc, tin, and some alloys, such as Babbitt's metal, and experiments have been made with aluminium which promise complete success. The applications-of Ribbon Metals are many and various:-- 1. .Probably the most important will be in the white lead industry, for Ribbon -Lead is in a form peculiarly suitable for the manufacture of white lead either by the " Stack " or " Chamber " method. Small scale experiments have shown that Ribbon Lead even when pressed together into a cake of about half the density of solid lead is uniformly and evenly attacked by the ordinary corroding gases used in the manufacture of white lead by the " Stack " and " Chamber " pro cesses, and is converted into white lead in about twenty-four hours, whereas about one hundred days is the time required to complete the corrosion by the present methods. >5? It seems reasonable to expect that a large and important industry will be transferred from the Continent to the United Kingdom, and that " Chamber " white lead,'which is now almost entirely imported from abroad, will in future be made in this country; especially as white lead which can be guaranteed as " English Corroded " secures a substantial premium over the imported article. 2. Another very important use far Ribbon Lead is for metallic joint packings in water, gas, and steam pipes, in the place of the more expensive and less, suitable cut shavings of lead now used 3. Ribbon Leadis in a very convenient form for use in the construction of secondary batteries. 4. Metals can be provided in a convenient form for attack by adds and in chemical industries, . Aluminium for use in organic preparations and Thermit. Tin far the preparation of Tin Salts used in dyeing. 5. The alloys, such as Babbitt's metal, will take the place of the more expensive mechanically prepared shavings now made for engine or valve packings. 6. Ribbon Zinc can be made at a small cost suitable for the reduction of gdld and silver by the Cyanide process. At the present time sine turnings or shavings have to be used, and the cost of making these by cuttingor turningisvery considerable. As is also the case with Ribbon Lead and the other metals, it fa found that Ribbon Zinc is exceedingly active in chemical reactions. This fa very noticeable With the Copper Zinc couple. This behaviour fa possibly due to the extreme suddenness of the solidification. 7. Ribbons and Tapes of metal can be made, and probablyalso metal foil, thin sheets, and electric fuses. There fa a possible application for certain of the Ribbon Metals in the textile industries. 8. Metallic Felt can be mads for filtering purposes and the metal recovered and used over and over again owing to the cheapness of the process. 9. Ribbons have been made from rfav inch upwards in thickness, and are exceedingly suitable far decorative purposes. There is no doubt that as other metals are tried many other uses will be found for theprocess, for-there seems to be no reason why any metal should not be successfully treated under proper conditions. Patents Nos. 6639, 6630 (1907), and No. 7211 (1908) have been secured in Great Britain. Patents have also been applied for, and in some cases already granted, in the Colonies, and all other important countries. The Industrial Chemical Company, Limited, of Rainham, Essex, wdl undertake the manufac ture of Ribbon Metals for laboratory and experimental purposes, and will pay a royalty of 75 per cent, of the net profits after deducting a sinking charge for expenses incurred in erecting the plant. This plant fa ready to be installed, and will be available for demonstration purposes. The Industrial Chemical Company, Limited, are also willing to give facilities for the election of a White Lead Chamber of a size suitable' for manufacturing, and willact as sellingagentsfor the white lead if required. 0007-SWP-000122210 4 The process of malting Ribbon Metals was shown in December last at the Exhflrition -of the Physical Society of London, and at the Royal School of Mines, and in Janoary at the Royal Insti tution, and created much interest on each occasion. The apparatus has been set up at No. 50 City Road, E.C., and the process of manufacture and some of the applications of Ribbon Metals can be seen there any day between the hoars of zi a.m. and 4 p.m. Admission on presentation of visiting card. No. 50 City Road, is about midway between Finsbury Square and Old Street. The nearest stations are:-- Moorg&te Street--Metropolitan Railway. Old Street--City & South London Tube Railway, and Gt. Northern & City Tube Railway. London County Council tramcars and several lines of omnibuses pass the door. Negotiations are in progress for the sale of some of the foreign rights. An option has been granted for a substantial consideration to an American financial firm to purchase the American and Mexican rights for a sum of 25,000 in cash, and 10 per cent, of the stock of any Company or Companies formed to develop those rights. It is stipulated that there shall be only one class of stock issuedof such Company or Companies, and that no Debentures, Loans, Mortgage or Preferred Stock shall be issued without the consent of the English Company. The English Company is also to have the right to nominate one Director from time to time on the governing body of such Company or Companies. Arrangements have been made with a gentleman who has agreed to proceed to the Argentine, Chile and Peru at his. own expense to dispose of the South American rights on somewhat similar terms. A like arrangement has been made for dealing with the French rights, and negotiations are pending with regard to the other European rights, and the Australian and other Colonial and Foreign rights.

ProoBM tor Manufhoture of White Load. I, Gx ir at PaariHOT of lio. 4 Hart Street, Bloomsbury, in the County of London, Profeuor af Chemistry do hereby declare the nature of thie invention to be u follows:-- Is. manufoatjaring whita lead by acting with carbon dioxide on a lead (aide in 5 the presence of suitable reagents such as aoetio acid or its compounds, great difficulty is experienced in obtaining for this purpose .an- oxide sues as will pro duce whita lead of a clear white colour. One cause of this difficulty seems to be that lead oxides of commerce, such for instance, as litharge, are .mixtures of several compounds of lead with oxygen, which are differently acted on by the 19 reagents employed, so that soma of these oxides become converted before others id them, ana whan the reaction is continued in order to convert those others, those first converted are apt to be rendered crystalline, thus greatly impairing the value of the product My invention relates to a process whereby I can overcome the difficulty above 16 stated, and can obtain from ordinary mixed lead oxides a clear uniform white lead without crystals, in the following manner. I first partially deoxydue the crude lead oxides, by exposing them at a temperature of 250 to 300 C. to the action of gas rich in hydrogen, such for instance as water ns. This operation may be conducted in revolving vessels, or DO in stationary vessels provided with agitators, and with Suitable worms or other dised product, which is thus reduced to AA s_ itj. is -oJf _aJd_v__a__nJt_a__g__e_ xt_o---c---o----o1l itlh--e ^ atmosphere, the delivery passage or passaged should he water jacketted or otherwise kept cool. Having thus reduced 2d the material to the uniform condition of anboxide, I hydrate and oxidise it by slaking it with water and exposing it to the air, the suboxide being thus con verted into a higher oxide, probably monoxide. Finally, I subject this oxide mixed' with water, sugar and aoetio acid or an acetate, such as acetate of lead, to the action of carbon dioxide. The proportions of the charge may vary; SO practically I find a suitable proportion to be:--Hydrated lead oxide about 900 lbs., water about 250 gallons, commercial acetic acid equivalent to about 14 lbs. of the pure chemical-acid, (or the equivalent of this in lead acetate! and sugar about 45 lbs. Tbe liquid portion of the charge, after the white lead is separated from it, may be used with successive charges of lead ocrida 85 This operation, is conveniently performed in revolving veisels, the gas, when it is pure, being admitted through a trunnion under a little pressure. When the carbon dioxide gas it mixed with air or other gases, it is of advan tage to employ in rotation a series of carbonating vessels with inlet through the one trunnion and outlet through the other, so that the surplus gas can he eon- 40 ducted from the one to the next in order, until the whole of the carbon dioxide or nearly the whole is absorbed.

A Process for Manufiooture of White Lead. I, Gu s t av Bis c h o x , of No. 4 Hart Street, Bloomstnuy, in the County _ of London, Professor of Chemistry, do' hereby 'declare' the nature of this invention and in what manner the same is to ho performed to he particularly described and ascertained in and by tfye. followip^statejnejt. ,,. In marlnfaatnring white lead by acting with carbon dioxide on a lead oxide in 5 the presence of suitable reagents such- s acetic acid or'its compounds, great difficulty is experienced in obtaining for this purpose, an oxijle such as will pro duce white lead of a clew white colo.ur. Pne yauae of this ^lffipulty seems to be that lead oxides of odmmerce, such for instance ' as litharge, are mixtures of several compounds of lead with oxygen, which arc differently acted on by the 10 reagents employed, so that tome of these oxides-become converted before others of them; and, when the reaction is continued in order to convert these others, ' those first converted are apt to be rendered crystalline, thus greatly impairing the value of the product. ..................... My invention relates to a process whereby I can overcome the difficulty above 15 stated, and can obtain from ordinary mixed lead oxides a dear uniform white lead without crystals, in the following manner;-- I first partially deoxidise the crude lead oxides by exposing them at a temperature of about 260 to 300 G. to the action of gas rich in hydrogen such for instance os water gas; but care should be taken to avoid the presence .of SO sulphur compounds. This operation may he conducted in revolving vessels, or in stationary vessels provided with agitators and with suitable worms or other conveyors for delivering the partially deexydised product which is thus reduced to the condition of sub- oxide of lead, probably corresponding to the formula Ph^O. As it is of advantage 25 to coal the product before it leaves the deoxidising atmosphere, the delivery passage or passages should be water jocketted or otherwise kept Cool. Having thus reduced the material to the uniform condition of subaxide, I hydrate and oxidise it by moistening it with water and exposing it to the air, the subaxide being thus converted into a higher oxide, probably monoxide, wlpah may SO be expressed % the formula FbH^O,. Finally, I subject this oxide mixed with water and acetic acid or an acetate, such as acetate of lead, and preferably with sugar, to the action of carbon dioxide. The proportions of the charge may vary; practically I find a suitable proportion to be:-- 35 Hydrated lead oxide about 900 lbs., water about 260 gallons, commercial acetic acid equivalent to about 14 lbs. of the pure chemical acid (or the equivalent of this in lead acetate) and sugar about 4o lbs. The sugar however is net absolutely necessary, but is useful in promoting the reaction. The liquid portion of the charge after the white lead is separated from it, may be used with 40 successive charges of lead oxide. This operation is conveniently performed in revolving vessels, the gas, when it is pure, being admitted through , a trunnion under a little pressure. When the carbon dioxide gas is mixed with sir or other gases, it is of advan tage to employ in rotation a series of carbonating vessels with inlet through the 45 one trunnion and outlet through the other, so that the surplus gas can be con ducted from the one to the next in order, until- the whole of the carbon dioxide or nearly the whole is absorbed.

They wars ut in racks so cons truetad as to antlraly cover ona third tha panel (leaving two-thirds exposed to tha sun and atnoaphars) and placed on the aast roof of tha "5" Building vhnra the sun shone until 1 p.ra.

Others wars expossd for thrss months - 6 months - 9 months and s year according to the 3use* X had on lb* racks. H a colors wars -cade throughout wit1', lake Oalumet water. In order to facilitate tha work and systematise the records, each panel was raarked into ona of five frri-dss:- GHAC2 A. - signified tbit tha panel had undergone no praoticaly change. GRADE 3. - a slight change but not to a bsd ehruip-e. SHADE 0. - considerable chan*-? but still on ordsr of original color. SHADE D. - badly changed and very dirty. GilAJDS 2. - "all pon^ to piee-s". Dot much th:.t eou:S i?dic:t origin 1 color. Tha Usds should ill ba in SHADE A - to be called good and not fugitive. But tha grade of "B" in a Yellow won 3 mean that It was real pood and the grade "A" [seldom s c b ) would mean that It was excellent. TMs vault1, apply also to ths Greers, although prtd? in rrsar. . ou'.d aapt: thet it was unusually poor, -while in a Yellow, it would be as "ood vs the tver^-e sen; on the arket to-day. There ware 20 batches Of 10C04 e:.pcsed. 15 of t'.esa, ware grade 'A'* on 1 mouth's exposure, and grade "0" nearly to "D" on 3 month's exposure, v-hil.e two cf them had gon-s to pieces entirely and wera grided "E".

All were "D" or nearly so far three months. This eolor was very fugitive. The two teste made on 10063 were very poor, and showed a fugitive color. One was gradsd "A" for 1 month, but "E" at end of 3 months. The other faded to grad? "E" in 1 month and waa entirely whit*. Five exposures of 10064 wers graded "A" for onemonth.

Thee* last ten were all mad* at about same time (June *06} and I believe at this time we were havlnr trouble with the Para from ifetz. An average for 10091 whan the dye iff right, would be abouta Grade A - on* month. B - three " 0 - six " All the six tests made on 10096 were graded "A" for on# month. Three wars graded "3" at end of 3 months. Two were graded "C" at end of six months, and one of theae was still grade n3M at end ofy#ax. Yihat few tests were mads om thlfc color ease out wall and it seemed to be quite permanent. Thera wars 35 panels exposed of 10109. Bone of these failed to be grade ''A" in one month or worse than grade "B" in 3 months. One waa a grade "C" in 7 months. 15 were graded "3" at and of 5^ mouths, and seme at end of 7 months.

Three' of them had turned much darker at e^ul of 3 months and were a grade "3" hut nearly "3". At end of 6 months they had turned to a grade "D". One teet on 10120 was graded "A" for one month. Two teats on 10121 resulted in grade "A" for one month and grade "3" for four months. One exposure on 1/Q122 was graded "A" one month and "C" at end of 4& months. One panel was exposed of 10124 which was graded "A'1 for one month. "B" for four months. There were 12 panels exposed of 10125. Sine were graded "A" for month and "B" at end of four months. Two of the 12 were graded "B" for onemonth and one "C" for one month. Fourteen expoeuros of 10126 were graded "A" for one month. 3sv-n were dirty and hadly faded in 3 months to a grade "ft". Two were grade "A" at end of 4 months. One was grade "B" at end of 6 months. It war entirely gone. Four teste of 10128 resulted in a grade 'A" for one month for 3 of them a nd grade '*3* for one month for the dther. At the end of 3 months all had faded to a grade "0N. They were much deeper in shade sad quite dirty. In 7 months one had turned to grade "D". Seven testa were made on 1/0129. These were all grade "A" a$ end of ona month. Five were grade "0" at end of months. One woe "5" for 3 months. Ona was graded "Dn at end of 4* months.

Three changing to a grade "0" in 6 months. Four were still gr.de "B" at end of 9 months and two were grade "B" at end of year. This color seem'd tc altrays hold its color well but changed gradually.to a deeper shade. Sixteen testa of 10132' resulted in grade "A" for 14 of them at end of a month. Four were graded "A" at end of 3 months. Six were grade n3" at end of 3 months. Five were grade "3" at end of 8 and 9 months and one was grade "B" at end of a year. Three changed to grade "0" in 6 months. Iwo to grade "D" in 4 months. This color was also one of the most permanent. Contrary to what was expected of 10133 X found this to be the most Irregular and most fugitive of the Rede. It didn't exactly fade but changed to a vary dirty color first and then faded. Out of 2C exposures made, only seven were grade "A" at end of one month. These changed to "C" (one to "D") at end of 3 months. Four were a grade "a" at end of one month. Six were a grade "C" in same tfcre and three were so much changed at end of a month as to be graded "D". 0007-SWP-000122222 BUA- 4. ' were grade "3". Twenty-el^ht were graded "B" at end of 3 months.

They did not seem to fade hut seemed to turn to a deeper shads of Green, and in a good many Instances to a richer shade. Th^ usual occurrence woe to turn to a slightly deeper shade ( a good shade B) and remain that war for a good While. As a whole think they "stood up" very well end would compare favourably with any Greens on the market. v. Twenty-nine tests on 11000 resulted in a grade "B" for 20 of them at the end of one month. Eight were graded and one was graded "B". This last was made on September 12 '06. On tliie day the water was unusually warm, very rlley and dirty. There were 85 exposures nade on 110C1. 77 of these were graded "B" at end of one month and eight were graded "C" in same time. Fom*t'en were still "3" at end of two months and twelve still remained "3" at end of 5 months. Ten exposures of 11CC2 resulted in all being of a grade "B" at end of one month.

In this case they were made exactly the aare - one the B&ma day - p?intad at the same time -:nd exposed the a;.ms. This 1? only ono of a great many similar occurrences.

The molten Lead is run from tike melting pot Into large tubs of water which causes It to harden in thin sheets of irregular shape. It ie then taken from the water, run along on trucks over tube containing weak Aaetie Acid, und ie then dropped into these tube, where the Basie Lead Acetate is fanned. Carbonic Acid nae (CO.) ie then blown into this mixture, v ich fence the Carbonate cf Leed. It it then allowed to aettlo and the upper liquor drawn off, and used again in the Acid tuba. The precipitate ie next washed thoroughly, and them pumped to chamber filter presses, where about 30?. of the mixture is extracted. It ie taken froi-i the filter on traye, which are pit into rooks twenty high (three tiers), and then passed on through a drying kiln, into which hot air is blown at a temperature of about 150 degrees. These traye are next dumped into shoots which feed the Lead to the chasers, where it is ground in the dry state. In the chasing the Lead can be mads more dense. The powdered Lead ia then conveyed through a conveyor to the depart* ment where it is packed In parcels, or to where it is put iric mixers to be mixed with oil, and then ground in rolling mills :.nd filled into kegs through a conveyor. In the process of mixing, this must not be interrupted until the mixing is completed. This process makes a very white lead, shier. is also very soft vr.d quite bulky . A bull-'lag 50 feet by 110 ft (3 stories) with 5 men to operate the machinery, has a capacity of 10 tone per day. The process tafc~s about lu days, about 2 tons each day taker, from the tubs, end 2 tons of fresh lead addei each day.

The change in color was toward darkening and, although this new goods la not as fugitive, as the other still it is not what you would call a permanent red and in fading tends toward a lighter and yellower shade. 3985 has not yet been made void, although it probably will be dead except at such times as some of Vnv customers demand some of the old goods, as I believe that it was used to some Blight extent for other purposes than ^ Bulletin Bed,. 621, an Artificial Vermilion made for the ffavy Depart ment of the U.S. government, is what is known as a Lithol Bed. - I am asking Ur. Ashby to send you a copy of the formula and what de structions are neoeasary in the making of the material. A eta^Hrd sample of the Bulletin Paste and of D 621 I am forwarding to you under separate oover, the formula however, going in a paokage of otherB which will also leave here today.
