Patent GB-1508826-A (GB)
Title: Electroplating
IPC: C25D5/02
Filed: 1975-05-20
Abstract: For the purpose of local electroplating of strip material (6), a rotating cylinder (3) having a locally enlarged diameter (4) at one end is immersed in a container (1) filled with plating solution (2). The surface of the cylinder consists of electrically non-conductive material. An anode (5) is immersed in the plating solution at a distance from the cylinder (3). As the cylinder (3) rotates, a layer (7) of plating solution is carried along which effects the conduction of a current between the anode (5) and the strip material (6). As a result of capillary action, a layer (8) is retained between the cylinder (3) and the strip material (6). The strip material (6) is moved axially with respect to the cylinder (3). Direct contact between the cylinder surface and the strip material (6) is thus avoided and the wear of the cylinder and the deposit is considerably reduced. Accordingly, the coatings from expensive metals electroplated onto electric components to improve contactability can be produced more cheaply, because a uniform layer can be formed even at small layer thicknesses. <IMAGE>

Abstract: 642,862. Feedwater regulators for steam boilers. McDONALD, J. Aug. 14, 1948, No. 21512. [Class 123(ii)] [Also in Group XI] The level of water in an electrode steam boiler 13 is controlled by an externallylocated float-valve assembly 26 which is connected by elbows 24, 24 to short pipes 22, 23 projecting from an upper feedwater supply tank 12 and the boiler proper respectively and the vertical position of which, with respect to the boiler, may be adjusted by replacing the said elbows by elbows of relatively different lengths. In a modification the valve assembly 26 is mounted between swivelling pipes extending substantially horizontal from the said tank and boiler. The steam space of the boiler and the casing 25 of the float valve communicate with the upper end of the tank 12 through pipes 28, 27 respectively, and the tank is provided with a water inlet 21 and a steam outlet 30 and the boiler preferably with a valve-controlled hotwater outlet, not shown.

Abstract: 460,585. Magnetic switches. AUTOMATIC ELECTRIC CO., Ltd., SMITH, S. R., and WOODHEAD, H. S. July 29, 1935, No. 21533. [Class 38 (v)] [Also in Group XXX] In an electric switch suitable for operation by the passage of a tramcar operating on the conduit system, the plough provided on the tramcar for current collection purposes is arranged to shunt the field of a permanent magnet located adjacent to the slot rail and thereupon effect the release of an armature normally attracted thereby, the said armature carrying contacts controlling the required circuit. As shown in Figs. 1 and 2, the permanent magnet comprising a cylindrical member 13 is mounted in a casing 16 below the road surface at one side of the conduit slot rail and the controlled switch member is similarly mounted in a casing 11 at the other side of the slot. The switch member comprises an armature 28 pivoted at 29 and normally attracted against a pole face at the end of a magnetic rod 25 secured to a plate,26 opposite the permanent magnet. On the passage of a tram, a magnetic plate attached to the current-collecting plough shunts away the flux of the permanent magnet from the apparatus in the right-hand box so that the armature is released and drawn away by a spring 35 to engage a fixed contact 42 and complete a controlled circuit.

Abstract: 373,847. Generating high frequency oscillations. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Hansell, C. W.; Port Jefferson, Long Island, New York, U.S.A.) July 28, 1931, No. 21592. Convention date, July 28, 1930. [Class 40 (v).] Ultra short-waves are produced by passing a discharge through a colloidal solution. In one arrangement a glass or quartz tube 2, Fig. 1, terminated by metallic electrodes 4, 6, contains a metallic colloidal solution, the particles being preferably of uniform size. From a source 8 are applied chopped high voltage unidirectional potentials or radio frequency potentials superimposed upon a direct or alternating potential. In this form a disruptive discharge is avoided and the ultra short waves produced by the particles are focused into a beam of radiation by the parabolic reflector 10. The reflector and tube may be immersed in a liquid identical with that inside the tube. In another modification, a parabolic container 14, Fig. 3, of glass or quartz is silvered or sputtered with a metallic coating and filled with the colloidal solution under pressure by means of a valve 12. The discharge takes place between electrodes 16, 18 and provision is made to enlarge and continually change the path of the discharge by applying a direct or alternating electric field at rightangles to its general direction. A disruptive discharge may be used, electromagnets causing the discharge to wobble continually to a fresh path, and this effect is increased by making the colloidal particles of a magnetic nature.
