Title: Improvements in process for Nickeliding, Cobaltiding and Ironiding Base Metal Compositions
IPC: C25D3/66
Filed: 1967-10-27
Abstract: 1,199,038. Electrolytically nickeliding, cobaltiding and ironiding metals. GENERAL ELECTRIC CO. Oct. 27, 1967 [Nov. 10, 1966], No.48887/67. Heading C7B. A method of forming a nickelide, cobaltide or ironide coating on a metal composition, the composition having a melting point of at least 800 C., at least 50 mole percent of said metal composition being at least one of the metals selected from the class consisting of metals whose atomic numbers are 27 to 29, 42 to 47 and 74 to 79 inclusive, which method comprises (1) forming an electric cell containing said metal composition as the cathode, joined through an external electrical circuit to nickel, iron or cobalt as anode and a fuses salt electrolyte comprising (a) one or more of the alkali metal fluorides or a mixture of one or more alkali metal fluorides or a mixture of one or more alkali metal fluorides with one or more of the fluorides of calcium, strontium and barium and (b) from 0À01-5 mole percent of the fluoride of the anode metal, said electrolyte being maintained at a temperature of at least 700 C. but below the melting point of said metal composition in the substantial absence of oxygen and (2) controlling the current flowing in said electric cell so that the current density of the cathode is in the range from À01 to 10 amperes/dm<SP>2</SP> during the formation of the coating. The terms "nickelide", "cobaltide" and "ironide" designate any solid solution or alloy or intermetallic compound of Ni, Co or Fe and the base metal. The cell generates electric current. The deposition rate of the Ni, Co or Fe may be decreased by inserting some resistance in the circuit or may be increased by impressing a voltage, e.g. to obtain constant current densities during the reaction. Specified fluorides that may be used are those of Li, Na, K, Rb and Cs, e.g. a eutectic mixture of NaF and LiF. The process may be carried out under vacuum or an inert atmosphere, e.g. of N 2 , Ar, He, Ne, Kr or Xe. The electrolyte may be purified, e.g. from carbon, by an initial electrolysis. Ni, Co or Fe may be used as anode in the form of a rod or in the form of chips in a porous Cu or graphite basket. A graphite basket may be shielded with metal cloth to prevent carbon fragments from getting to the cathodes.

Abstract: 1,026,829. Refrigerators. WESTINGHOUSE ELECTRIC CORPORATION. Dec. 15, 1964 [Jan. 9, 1964], No. 51020/64. Heading F4H. A resiliently flexible breaker strip for a refrigerator cabinet comprises a front edge portion 29 which engages a flange 19 of the outer shell 11, an intermediate arched portion 28 and a bifurcated rear portion having limbs 31, 32 adapted to engage with the inner liner 12. The front edge 21 of the latter is provided with an outwardly directed flange 26 having a rearwardly directed leg 27. When the liner 12 and shell 11 are in the relative position shown, the junction of flange 26 and leg 27 engages in a notch at the outer end of link 32, and the outer end of the breaker strip portion 29 abuts a rearwardly directed wall portion 22 of the outer shell. If, due to manufacturing tolerances, the spacing between the liner and shell is greater in the transverse direction and less in the rearward direction than that shown, then this is accommodated by spacing the end of portion 29 from wall portion 22 and allowing the flange 26 to bear against an intermediate portion 34 of the limb 32 (Fig. 4, not shown). The breaker strip is formed of a styrene acrylonitrile copolymer and the insulation 18 between lines and shell may be glass wool or polyurethane foam.
