Title: Improvements in or relating to the formation of metal coatings by electro-deposition
Inventor: SALT FREDERICK WILLIAM
IPC: C25D15/02
Filed: 1965-01-27
Abstract: Metal coatings are formed on a metal substrate, e.g. a sheet, strip, wire or rod, by immersing the substrate in a solution containing a source of the metal ions which are to be deposited (e.g. Cu, Ni, Fe or Zn ions), a cationic surfactant and suspended finely-divided metal particles (e.g. Fe, Zn or Cr powder) and creating a potential difference between the substrate, connected as the cathode, and an anode which is also immersed in the solution, whereby simultaneous electrolytic deposition of the metal and electrophoretic deposition of the suspended particles on the substrate takes place.  The surfactant may be cetyl trimethyl ammonium bromide, dodecylamine hydrochloride or cetyl pyridinium bromide.  The solution may also include quinoline and one or more compounds to suppress gas evolution e.g. a redox system such as an iodine/iodide, ferri -cyanide/ferrocyanide, ferric/ferrous or quinone/ hydroquinone system or a reducible organic compound such as nitrobenzene, acetaldehyde or glyoxylic acid.  The solution is agitated during the deposition and the degree of agitation may be such as to produce foam.  The metal powders used may have a thin oxide film on their surface, e.g. Fe powder heated to 170 DEG C. for 1 1/4 hours in a fluidized bed through which air or oxygen is passed.  Simultaneous electrolytic and electrophoretic deposition of metal followed by rolling may be repeated until a coating of a desired thickness is obtained. The process may be used in producing galvanized steel strip without the application of heat.  In the manufacture of steel strip, Fe or steel is simultaneously electrolytically and electrophoretically deposited on a substrate, e.g. a strip or roll, is stripped off and subjected to annealing and temper rolling.  Two or more metals can be simultaneously electrophoretically and/or electrolytically deposited, e.g. deposition may be from a suspension of Cr powder in an electrolyte containing Fe and Ni ions.

Abstract: 582,634. Helicopters. UNITED AIRCRAFT CORPORATION. Feb. 26, 1944, No. 3596. Convention date, Feb. 27, 1943. [Class 4] A helicopter with variable-pitch blades mounted on flap and drag pivots is provided with means, independent of the pitch control, for effecting tilting of the rotor head and pitchchanging mechanism about a transverse axis in order to counteract changes in the longitudinal position of the centre of gravity of the machine. In the embodiment illustrated, simultaneous and cyclical variations in blade pitch are effected by a gimbal ring 68, axial movement being imparted to the ring by members 116, 120, fore-and-aft tilting movement by member 88, and transverse tilting movement by differential movement of threaded members 72 operated by screwed sleeves 78, 80, driven by member 102 through chain-andsprocket gearing 94. The rotor head 28 is mounted on transverse trunnions 30, about which it may be rotated by a screwed shaft 132 operated by a chain-and-sprocket drive 138, 140, 142. The pitch changing mechanism includes a parallel linkage 112, 116, in order that tilting of the rotor head may have no effect on the pitch setting of the blades.
