Abstract: 1328234 Electrolytically applying nickel to steel HENKEL & CIE GmbH 9 Sept 1970 [10 Sept 1969] 43057/70 Heading C7B [Also in Division C1] In a process for the electrolytic application of nickel coatings to degreased and pickled steel surfaces and thereafter applying inorganic enamel by direct white enamelling, the nickel is electrolytically applied by treating the steel for less than 15 seconds with a solution which contains a water-soluble nickel salt (such as nickel sulphate and/or chloride) and 10 to 60 mg/l of a non-ionic wetting agent at a current density of from 1 to 10 A/dm<SP>2</SP> and at a temperature of 45 to 70‹C. The wetting agent has a turbidity point below the treatment temperature and is such that its solubility increases as temperature is lowered. During the electrolysis, in order to obtain a uniform nickel layer, at least part of the solution is continuously or periodically removed from the process, cooled to below the turbidity point, (optionally filtered), reheated to the treatment temperature and returned to the process. The solution may contain lustring or levelling substances (unspecified) and also H 3  BO 3  for regulating the pH to 3-5. For the non-ionic wetting agent, various ethylene oxide and/or propylene oxide reaction products are specified. In the Examples the nickel-plated steel is passivated with sodium phosphate solution before being direct-white-enamelled.

Abstract: 998,612. Disc brakes. BENDIX CORPORATION. Nov. 28, 1962, No. 45008/62. Heading F2E. A disc brake comprises a rotor, anon-rotatable housing overlying a portion only of the surfaces of the rotor and supporting a friction member which includes a backing plate 44 and a lining 46. An anchoring means comprises a pin 28 extending from the housing through the backing plate and into a portion of an opening 54 formed in the lining at its end remote from the geometrical centre in a direction opposite to the direction of rotation of the rotor. In the construction shown a further pin 30 is screwthreadedly secured in the calliper housing and co-operates with a slot of the friction member. A friction member is mounted on each side of the rotor and each is applied by an hydraulic piston 62. The force P applied at the geometrical centre of the friction member is offset from the reaction N of the disc by an amount e on account of the frictional force between the pin and the abutment surface. With the wearing of the friction lining 46 the distance e becomes smaller and finally negative to produce uniform wear of the friction pad. If the disc is to be braked in both directions of rotation a second abutment surface is provided adjacent the originally trailing edge of the friction member to co-operate with pin 30 (Fig. 5, not shown).
