Patent GB-836480-A (GB)
Title: Improvements in or relating to alloy plate
IPC: C23C18/34
Filed: 1958-01-07
Abstract: Catalytic material is coated with a nickel-boron or cobalt-boron alloy containing 4.5-7% boron by being contacted with an aqueous alkaline solution containing a nickel or cobalt salt, a borohydride, and, as a nickel or cobalt sequestering agent, ammonia or an organic compound containing one or more amino, imino, carboxy or hydroxy groups.  The catalytic material may be nickel, cobalt, iron, steel, aluminium, zinc, palladium, platinum, copper, brass, manganese, chromium, molybdenum, tungsten, titanium, tin, silver or carbon; further, non-catalytic material such as glass or plastic, e.g. polystyrene, may be rendered catalytic by producing a film of catalytic material on its surface, e.g. by dipping into stannous chloride solution and then contacting with palladium chloride to produce a palladium film.  The nickel or cobalt salt may be the chloride, sulphate, formate or acetate; the borohydride may be the alkali metal, e.g. sodium or potassium, salt or may be substituted, e.g. sodium trimethoxyborohydride; and the sequestering agent may be ethylenediamine, diethylene triamine, triethylene tetramine, ethylenediamine tetraacetic acid, citric acid, tartaric acid and salts and related polyamines and N-carboxymethyl derivatives. The initiation of the coating process may be accelerated by contacting the surface to be plated with a more electro-negative metal while in contact with the coating solution.  Reference is p  made to heat-treating the coating at 600 DEG C. and to using it as an undercoat or overcoat for electroplated nickel, copper or chromium. U.S.A.

Title: Apparatus for processing elongated flexible material
Inventor: HARVEY PETER
IPC: B23D36/00
Filed: 1964-01-07
Abstract: 1,079,521. Printing apparatus. BRITISH INSULATED CALLENDER'S CABLES Ltd. Jan. 6, 1965 [Jan. 7, 1964], No. 711/64. Heading B6C. [Also in Division G3] In apparatus for processing flexible material, e.g. printing numbered marks at one yard intervals on P.V.C. covered cable, the processing device is driven by an electric motor whose speed is controlled in response to the difference in angular position of the processing device and a metering wheel in contact with the cable, which is drawn through the machine by separate means. The difference signal is preferably derived from a rotatable potentiometer, the wiper being coupled to the metering wheel and the winding rotated by the motor. The centre of the winding is kept at earth potential and when the slider is displaced from this point a voltage of appropriate sign is developed and applied to a transistor amplifier to energize one half or the other of the motor's split field; its armature is energized with constant current. The amplifier includes a resistance/capacitance stabilizing circuit. For the cable printing application a counter operated by the printer causes the cable to be slowed and then stopped and severed at a predetermined count. The printing device (Fig. 2, not shown) rotates on a shaft (16) and comprises a pair of printing wheels (26) which contact the cable once per revolution and are indexed by a stationary cam (20). Either an inked ribbon (27) or an inking roller (29) is used. It is stated that two separate potentiometers may be used for the error signal generator, and an alternative application is to correlate the head speed of a twisting, cabling or stranding machine to the linear speed of the cable.
