Title: An improved method and bath for the electro-deposition of an indium-cadmium alloy
IPC: C25D3/66
Filed: 1956-02-28
Abstract: 830,411. Electrodeposition of cadmiumindium alloys. PHILCO CORPORATION. Feb. 28, 1956 [May 23, 1955], No. 6150/56. Class 41. Cadmium-indium alloys are cathodically deposited by electrolysis of an acidic solution of cadmium and indium ions in a polar organic solvent at an elevated temperature, the solution containing also a polybasic acid which forms soluble complexes with the cadmium and indium. The ratio in which the metals are present in solution is the same as in the alloy deposited. The bath temperature may be above or just below the melting-point of the alloy deposited but preferably is in the range 122.5 to 160 C., so that the deposit is molten. Suitable solvents are polyhydric alcohols, e.g. glycerol, 1 : 2 : 4-butanetriol; glycols, e.g. ethylene glycol, propylene glycol; polyethylene glycols, for instance diethylene glycol; glycol derivatives, for instance ethylene glycol monobutyl ether; high-boiling amines, e.g. triethanolamine, N : N : Nl : N<SP>1</SP>-tetrakis (2-hydroxy propyl) ethylene diamine; amides, for instance acetamide; phenol; phthalic anhydride; and benzoic acid. Suitable complexing polybasic acids are ethylene diamine tetra-acetic acid (EDTA), citric acid, and tartaric acid while to maintain the acidity of the bath ammonium chloride is preferably added as this improves bath conductivity as well as acting as a buffer and a flux for molten metal deposits. The alloy may be deposited on a cathode of iron, steel, nickel, platinum, silver, gold, or copper, and the anode may be of carbon, tungsten, stainless steel, or platinum. Typically anhydrous cadmium chloride and indium trichloride are dissolved in glycerol to which is added EDTA, tartaric, or citric acids and electrolysis is effected at 140 C. with an applied voltage of 15 volts to deposit a molten plating of an eutectic cadmium-indium mixture. Specification 830,413 is referred to.

Abstract: 165,901. Feldkamp, F. A. March 2, 1920. Multiple - filament lamps; filaments; supports for. - A second filament is automatically connected in circuit on breakage of the first. In the lamp shown, the main filament consists of t w o branches 10, 11 connected in parallel between one leading-in wire 4 and a conductor 12 which is normally connected with the other leading-in wire 5 by a spring arm 18 and a contact arm 19 held against the conductor 12 by means of a fusible wire 26 which holds back an auxiliary spring arm 21 secured to the arm 18. The wire 26 is connected across the mid-points of the filament branches 10, 11 by conductors 23, 24. On breakage of any part of the filament, current passes through the wire 26, which fuses and thereby releases the arm 21; the arm 19 thereupon springs into contact with a conductor 15 so as to complete the circuit through the second filament 14 connected to the conductors 9, 15. Expansion of the wire 26 is insufficient to release the switcharm. The arm 21 is insulated by a glass bead 22. In a modification, the arms 18, 19, 21 are replaced by a single spring arm having lateral arms to engage the conductors 12, 15.

Filed: 1917-05-17
Abstract: 112,718. Haines, G. B., and Duffield, G. B. May 17, 1917. Projectiles.-Consists in providing a projectile with two or more pivoted wings, so arranged as to be automatically extensible during flight to support the projectile in the air. Figs. 1 and 4 show a projectile adapted to be fired from a smooth-bore gun, wings D, D<1> being hinged longitudinally so that normally they fold around the body A, as shown. In flight, the wings are extended by airpressure under them, and this action may be assisted by springs L. To effect a further spreading of the wings, each one may be made in two sections, hinged together. The wings may be geared together. In a further modification, the axis of the hinge of the wings may be slightly inclined to the longitudinal axis of the projectile by adjusting the forward end of the hinge in a radial direction, the object being to attain a greater lifting-power. Fig. 7 shows the invention applied to a projectile for a rifled gun. The wings D are carried by rings H, I mounted on ball bearings. A collapsible vane K is secured to the ring H, to prevent rotation of the rings due to friction.
