Filed: 1929-06-20
Abstract: 314,084. International General Electric Co., Inc., (Assignees of Allgemeine Elektricitõts Ges.). June 22, 1928, [Convention date]. Electromagnets; cores.-The metal laminations of magnet cores, dynamo-electric machine slot-closing wedges &c. are held together by a mass consisting substantially of the products of reaction of polyhydric alcohols and polybasic acids or their anhydrides. Suitable materials are glycerine and phthalic acid anhydride. The products of reaction are applied in the A-condition in solution, for instance in acetone, to one or both sides of sheet metal plates, and the products of reaction are then converted into the hardened B-state by being heated. The metal sheets are then stamped to the required shape and stacked in layers. The stacked sheets are pressed together and the adhesive mass is converted into the C-state by further heating at a higher temperature whereby the plates become firmly stuck together. In order to improve the dielectric properties, single-value alcohols or monobasic acids may be added to the mass either separately or together. Softening means may be added such as drying or semi-drying oils. In order to harden the mass. the cores may be subjected. during or after production, to the combined influence of pressure and heat.

Title: An improved method of coating ferrous articles with magnesium and and magnesium-base alloys
IPC: C23C2/04
Filed: 1955-07-04
Abstract: A ferrous metal article is coated with Mg or Mg-base alloy without the use of a flux by pre-coating it with a metal soluble in Mg, immersing it in a molten pool of the coating metal, maintaining the article in the coating metal so as to permit the same to dissolve the precoating and wet and coat the surface of the article, withdrawing the coated article from the molten pool, and cooling the coated article to a temperature which will permit it to stand exposure to air without oxidation, the operations subsequent to the pre-heating taking place in an inert gas atmosphere.  The soluble metal may be Cu, Ni, Sn, Zn, Al, Be, Cd, Co, Pb, Si or Ag, and it may be applied by electroplating.  Before coating, the article may be cleaned as by pickling (e.g. inu 15 per cent HCl), wire brushing or sand blasting. The temperature of the molten coating metal is maintained at, or slightly above, the melting point thereof.  The method may be performed in a batch-wise or continuous manner, airlocks being necessary in the latter case.  An example describes the Mg coating of stainless- and carbon-steel screens and perforated sheets by (a) de-greasing with trichloroethylene, (b) cleaning anodically and cathodically, (c) cleaning with 60 DEG  Baume H2SO4, (d) electroplating with Cu in copper cyanide or with Ni in a Watts nickel bath, (e) dipping into hot 50 per cent HCl, and (f) dipping into Mg at 1400 DEG F. and then holding at 400 DEG F., the atmosphere being argon.
