NATIONAL AUTOMOBILE SHOW IN NEW YORK 



The twenty-tirst national automobile show will be held at 

 Crand Central Palace, New York City, January 8-15, inclusive. 

 It is expected that it will be the most successful as well as the 

 most important yet held, and 30,000 dealers have been invited to 

 attend. The annual dinner of the National Automobile Chamber 

 of Commerce will be served at Hotel Commodore, Tuesday 

 •evening, January 11, while the motor truck committee of the 

 Chamber will hold one of its most important meetings Wednes- 

 <lay following. 



The National .Automobile Show in Chicago will be held at 

 the Coliseum and Armory the week of January 29 to February 5. 



STORING AND PACKING GAS BLACK' 



In commercial practice there are four different processes of 

 manufacturing carbon black from natural gas, namely, the chan- 

 nel,' the small rotating disk, the roller or rotating cylinder, and 

 the large plate processes. The main differences of these methods 

 are in the size and shape of the surface upon which the carbon 

 is collected and the rate at which the moving devices actuate. 

 The channel process is probably the best method and is the most 

 extensively used. The production of carbon black by cracking 

 or thermal decomposition methods is not extensive. 



STORAGE BINS AND PACKERS 



The storage bins are made of galvanized iron and vary in size. 

 They are hopper shaped and located over the packers. 



The packers are very similar to those used in sugar refineries, 

 and are connected to the storage bins by spouts. An auger 

 works inside of a tight sheet steel tube, pressing the carbon into 

 a paper sack. The auger is so designed as to stop the waste of 

 the free-Howing stock running out past the blades of the auger 

 when the packer is stopped for changing sacks. The stock when 

 passing through the auger, keeps the hinged gates folded parallel 

 10 and against the top auger blades. When the auger stops, the 

 coil springs force the gates downward against the carbon lodged 

 between the blades, not closing the passageway completely, but 

 holding back the carbon sufficiently to prevent leakage. The ma- 

 <:hine is gaged to pack a uniform amount in each sack, which 

 is usually 12^ pounds, or a quarter of a barrel. In some cases, 

 especially for export trade, the sacks contain 15 pounds. The 

 j)acker stops automatically when the sack has been filled with 

 12^^ pounds of carbon black. 



The sacks are tied, and in most plants slightly compressed. 

 The compressor consists of a steel plate box, in which a plunger, 

 -actuated by a crank shaft or eccentric, travels. The sides of the 

 sack are flattened to facilitate storing and transporting. After 

 ■ compressing, another paper sack is placed over the package.

"SKOGUM" JAR RINGS OF RED RUBBER 



A new high-grade red rubber jar ring is called the "Skogura." 

 The makers claim it has passed the highest test ever given a 

 rubber ring. It is attractively packed in cartons showing a 

 scene on a rubber plantation. — Smalley, Kivlan & Onthank, 21 

 Blackstone street, Boston, Massachusetts. 



"CARMOJON DE-LUXE" INNER TUBES 



Pure plantation Para is used in "Carmojon De-Luxe" tubes, 

 which are made in three colors, brown, red and green. The 

 makers claim a special point of quality for each letter of the 

 name.— Carlisle Tire & Rubber Co., Carlisle, Pennsylvania. 



THE MARKET FOR CHEMICALS AND COMPOUND- 

 ING INGREDIENTS 



NEW YORK 



THE continued curtailed production of rubber goods of every 

 sort, particularly of automobile tires, has reduced activity 

 in the market for compounding ingredients very appreciably. 



In some cases, notably lithopone, production has been decreased 

 owing to lack of demand, which has also not responded to price 

 reductions in this and other ingredients. Prices on lithopone 

 for the first quarter of 1921 were announced early in December 

 and are quoted at 7^4 to 8 cents, an advance of J4-cent in an- 

 ticipation of increased spring demand by the paint-consuming 

 trade and rubber manufacturing industry. 



Decreased manufacturing activity in all branches of industry 

 has minimized the demand for raw materials of every sort, but 

 rubber manufacturers in common with those in other lines are 

 optimistic of a marked renewal of business by the spring months 

 of 1921. 



.Aniline Oil. Prices declined from 25 cents to 22 cents toward 

 the close of December, with the market weak and dull. 



Barytes. This material is in good supply, little demand and 

 steady prices. 



Blanc Fixe. The same conditions prevail as with barytes. 



Benzol. Prices fell off during the past month until they were 

 quoted at 28 cents for 90 per cent in tank cars, or 31 cents in 

 drums. And at 30 cents in tank cars for pure, or 36 to 38 cents 

 in drums. 



Blacks. The prices held steady at the usual figures regard- 

 less of the fact that in Wyoming strenuous efforts are being 

 made against the use of natural gas for the manufacture of 

 carbon black. 



China Clay. Foreign arrivals are said to be coming freely 

 and the market is well supplied. 



Carbon Bisulphide. The market is dull, with prices quoted at 

 8 to 9 cents per pound. 



Carbon Tetrachloride. Little demand in evidence. Quotations 

 are 10; ^ to 13 cents per pound. 



l^iTHARCE. .Slight changes in price occurred during the month 

 of December, notably ^-^ cent per pound reduction for litharge in 

 casks, which did not affect that in kegs. 



Lithopone. Stocks are not large and some producers have re- 

 duced their volume of output in the absence of active demand, 

 notably from automobile tire manufacturers. 



Sublimed Lead. Equally dull with the market for litharge. 

 The price level is maintained at 8^/2 to 8H cents per pound. 



Sulphur. The demand is moderate. Price on commercial 

 grade flour has been reduced to $1.60 from $1.95 per hundred 

 weight, and on the superfine flour from $2.75 to $2.10 per hundred 

 weight. 



Solvent Naphtha. This is not much in demand and is cheaper 

 at 28 to 30 cents. 



Talc. The demand is fair, with prices steady. 



Whiting. Good receipts of chalk are arriving and the demand 

 continues steady. 



Zinc Oxide. Although the market is dull, producers are still 

 operating mills at full capacity. Lead-free oxide advanced from 

 10 to lO'.t cents per pound. 



A dispatch fro.m the American consul at .Alexandria dated 

 November 10, 1920, states that the new cotton crop for Egypt 

 has been estimated at 612,000,000 pounds.
