Diphenyl Now Offered in Commercial Quantities
Industrial N o t e s A Bronze-Welding Application The head of a condenser used in the refining process at the plant of a starch-refining company suffered an 18-inch break, and it looked as if a serious loss would result. This condenser head was an intricate casting and would have been very costly to replace. The plant welder was called in and, after looking over the piece and examining the nature of the break, decided that i t would be best to preheat and bronze-weld. Under ordinary conditions preheating operations are not necessary in bronze welding. Owing t o t h e size and design of this job, *,-,-?r5.V'·' ••3;- f s ^ ï " j 2 ? % * i i > Î 7 . i however, the extra precaution was taken. Consequently a furnace of loose fire-brick was b u i l t u p . The condenser head was placed in the center of this temporary preheater, the base of the piece resting on t w o 6-inch pipes. The next steps were to clean the crack thoroughly with a stiff wire brush and prepare and light a charcoal fire under the casting. An asC o n d e n s e r Head Repaired b y Bronze bestos paper covering was Welding placed over the job and the entire casting was allowed to come to an even temperature. Bronze welding was then begun. A standard high-grade bronze rod was chosen and a good quality of flux used to float off impurities. After the weld had been completed, the casting was allowed to remain in the furnace i n a dying fire so that cooling would be gradual and uniform. The repair was a complete success.

Smithwelded Pressure Vessels The A. O. Smith Corp., Milwaukee, Wis., has prepared a bulletin on Smithwelded pressure vessels, which is available for distribution on request. The bulletin describes the characteristics and applications of Smithwelding, which is essentially a process of electric arc welding initiated and developed by the corporation over a period of 12 years. The corporation manufactures autoclave shells and process vessels to meet individual requirements and in any size up t o transportation limits, as well as steel pipe, casing couplings, automobile frames, oil cracking stills, etc.
A. M . Byers Co. The A. M. Byers Co., Pittsburgh, Pa., rxas developed a new process of making wrought iron by which it can be produced on a scale comparable with steel production. Work has started' o n a new plant near Ambridge, Pa., which is t o be completed within a year at a cost of $10,000,000. A t present wrought iron is being produced at t h e rate of about 5000 tons per month, at the company's temporary plant a t Warren, Ohio.
A N e w Stainless Steel An improved stainless steel which contains a considerable proportion of nickel in addition to the regular stainless steel analysis is now being produced in this country under Krupp Nirosta patents and under the supervisory direction of Benno Strauss, director of research of the Krupp Works, Germany. Three companies licensed t o ^operate under these patents are the Central Alloy Steel Co., Massillon, Ohio; the Ludlum Steel Co., Watervliet, N. Y.; and the Babcock & Wilcox Tube Co., N e w York, Ν . Υ. These companies have organized for joint research: and promotion on the new stainless product. Enduro ICA2, as the principal type is known, is re sistant to air, water, dilute solutions, and acids at high temperatures and at high, pressures. It can be deep drawn, wire drawn, spun, readily ma chined, and welded by either electricity or gas. It may be highly polished, is non-magnetic, and has approximately the ductility of copper.
Timken Steel & T u b e Co. The new mill of the Timken Steel & Tube Co., Canton, Ohio, has started on a full capacity production schedule of 30,000 tons of high-grade alloy steel per montb. The plant is the first of i t s kind to be completely antifrictionized, every shaft being equipped with Timken bearings. The ca pacity is about equally divided between electric furnace and open-hearth steels.
Lincoln Electric Co. The Lincoln Klectric Co., Cleveland, Ohio, has appointed J. E. Durstine as district sales representative for the Southeast, with headquarters a t Birmingham, Ala., and H. P . Egan as district sales representative for central Ohio, with, headquarters at Columbus, Ohio.
New P l a n t s at Memphis A new Prest-O-Lite acetylene plant, at 1241 North McLean Blvd., Mem phis, Tenn., commenced operations December 19, 1928, to supply near-by industries with dissolved acetylene for oxyacetylene welding and cutting. A new Linde oxygen plant started operations December 20. The old Memphis plant will be discontinued, and its superintendent, E. C. Heyman, will assume similar duties at the new plant.
N e w York Office of Foote Eros. Foote Bros. Gear & Machine Co. has established a New York branch office in the Wool worth Bldg., in charge of E. A. Phillips. This branch will have control of all territory in N e w England, N e w York as far west as Roches ter, and the northern half of N e w Jersey.
_ The Federal Phosphorus Company announces that it is now producing diphenyl (CeHfi-CeHs) on a commercial scale. The manufacture of this product was developed to supply the requirements of one of the oil refiners for refining lubricating oils. The use of diphenyl in boilers in place of water permits of high temperatures at low pressures. For example, it is possible t o maintain temperatures at 750° F. with a pressure of only about 115 pounds. Material that has been subjected to these conditions for several months has shown n o tendency t o decompose. Diphenyl offers the possibility of solving problems of distillation and evaporation in connection with products involving high temperatures. In addition to the refining of lubricating oils it offers possibilities in the following fields: (1) evaporation of high-boiling solutions such as calcium chloride and caustic soda; (2) distillation of high-boiling organic chemicals; (3) distillation of fatty acids; (4) bodying gums and oils for varnishes and print ing inks. Various derivatives of diphenyl show promise as intermediates for the manufacture of dyes.
C. H. Wheeler Mfg. Co. The C. H. Wheeler Mfg. Co., Lehigh and Sedgley Aves., Philadelphia, Pa., has appointed W. K. Kirby, 309 American Exchange Bank Bldg., Dallas, Texas, to handle its heat exchangers, oil vapor condensers, Leach fracto condensers, etc., in the states of Texas, Louisiana, Arkansas, and Oklahoma.
