Industrial N o t e s Goslin-Birmingham Mfg. Co. and Whiting Corp. Merge A recent example of the trend toward consolidation in the industrial field is the affiliation of the Goslin-Birmingham Mfg. Co.. of Birmingham, with the Whiting Corp., Harvey, Ill. The Goslin-Birmingham Mfg. Co. is the successor to the old Birmingham Machine & Foundry Co. and the Joubert & Goslin Machine & Foundry Co., both well known firms with many years of manufacturing experience, particularly in the sugar-refining machinery field. The Whiting Corp., with its subsidiaries (Swenson Evaporator Co., Grindle Fuel Equipment Co., and Joseph Harrington Co.), manufactures, among other things, special machinery of all kinds, evaporators, and chemical machinery for the process industries. The affiliation of the two companies represents a n unusual combination of manufacturing facilities and personnel, which should be of material benefit in extending the Whiting lines in the South. The two plants of the Goslin-Birmingham Co. are unequaled for capacity and completeness of equipment anywhere in the South. Of special significance is the research program begun by Whiting several years back. Through its subsidiary, the WhitingSwenson Co., Ann Arbor, Mich., the process industries have a rare opportunity to secure valuable research service on any problems pertaining to the transfer of heat, evaporation, crystallization, and the recovery of wastes. Very definite benefits have resulted from this research work, including the development of new and improved equipment that is saving their industries thousands of dollars each year. One of the outstanding developments along this line has been in connection with the concentration of caustic soda solutions. The new method and equipment resulting from this development have approximately cut in half the former cost of concentration. Another interesting development t h a t is about ready for commercial application involves the use of a Swenson forced circulation evaporator, with diphenyl as t h e heating medium, for the

production of solid caustic, thus practically eliminating the usual pot installation. Because of the diversity of its lines, the Whiting organization comes in contact with a wide range of engineering and manufacturing problems, and through its complete engineering staff is prepared to render unusual service on any special problem. Link-Belt Patents Promal—A New Metal for Chains A new line of cast chains showing remarkable strength and durability in comparison with malleable chains has been placed on the market by Link-Belt Co., Indianapolis. Thesechainus are sold under the registered trade name of Promal. They are the result of extended research to provide longer life for drive and conveyor chains operating under heavy loads or abrasive conditions. Experimentation with cast chain metals, started about four years ago, led to the discovery of a new method of processing malleable iron which so altered its physical characteristics as t o make it a distinctly new metal. This was recognized b>y giving it the distinctive name of Promal. Compared with malleable iron, Promal has an average yield point of 45,000 lbs. as against 36,000 lbs.; an average ultimate strength of 65,000 lbs. as against 54,000 lbs. ; an average elongation of 14 per cent as against 18 per cent; and a Brinell hardness of 170 to 190 as against 110 to 130. Compared with mild cast steel, annealed, Promal has an average yield point of 45,000 lbs. as against 34,000 lbs.; an average ultimate strength of 65,000 lbs. as against 60,000 lbs. ; an average elongation of 14 per cent as against 26 per cent; and a Brinell bardness of 170 t o 190 as against 120 to 140. Promal thus has, to a high degree, the qualities desirable in sprocket chain material; great toughness t o resist extreme tension without permanent stretch; high strength in proportion to* weight and size; and hardness that affords great resistance toabrasive wear. Because of their higher Brinell hardness, Promal chains withstand abrasive wear far better than the usual cast chain. Promal also has an exceptionally high yield point or elastic limit (25 per cent higher than that of average malleable iron). In addition, it is tough and ductile so that it withstands shock and fatigue loads. High temperature reduces its tensile properties somewhat, but temperatures up to 1000° F . will not cause it t o become brittle. Although laboratory tests indicated t h e better wearing: qualities of Promal chains when they were first developed, they were withheld from the open market for over three years t o permit extensive field tests. For these tests many chains were tried out in various industries through the cooperation of Link-Belt customers. A check was then kept on t h e performance of Promal diains while subjected to everyday usage. The results have txniformly sustantiated the laboratory tests. Details of the physical properties of Promal, with specifications and prices, may be obtained from Link-Belt Co., Indianapolis, by asking for Book No. 950. Tolhurst Machine Works, Inc., Enlarges Its Scope With the merger of the General Laundry Machinery Co. and the American Laundry Machinery Co., t h e Tolhurst Machine Works, Inc., which has been associated with the General Laundry Machinery Co.,· becomes an independent corporation. It has been long and prominently identified with t h e chemical industries through its engineering development in connection with centrifugal machinery of all types for its many applications t o chemical processes. Its position in the chemical industries remains unchanged except in so far as the move greatly enhances the engineering and production resources of the Tolhurst Machine Works, Inc. Glyco Products Co. to Sell Alkagel The Glyco Products Co. Inc., Bush Terminal, Brooklyn, N . Y., has been appointed exclusive sales agent for t h e eastern part of the United States and t h e export trade for Alkagel and sodium and ammonium alginates manufactured by trxe American Algin Co. These products are arousing interest a s waterproofing and alkali and salt waterproofing agents for concrete mortars, stucco plaster, etc. They are similarly used in treating textiles, paper, and leather. Low priced, durable, a n d beautiful plastics are made by using t h e Alkagels in combination with, powdered mica, wood-flour, asbestos, carbon, etc. Mixed with, rubber latex Alkagel makes a strong elastic film.

The Forest Products Laboratory, Madison, Wis., has resumed the publication of the leaflet "The Log of the Lab," which has for its object reporting the current research progress of t h a t labora- tory.
