Abstract: 1,189,182. Welding by fusion. AIR REDUCTION CO. Inc. 3 Aug., 1967 [12 Aug., 1966], No. 35769/67. Heading B3R. In consumable electrode arc-welding, the feed rate of the electrode is varied cyclically to achieve a pulsed arc-type welding. A power supply with a dropping, constant or rising characteristic may be used. The maximum feed rate of each cycle is such as to produce spray transfer. Metal transfer does not occur during the greater part of each cycle. Mild steel may be so welded with a shielding gas of 98% argon, 2% oxygen. The electrode may be fed by a programmed automatically controlled variablespeed motor. In one modification, the electrode 30, Fig. 6, is fed by a motor-driven eccentric feed roll 40 which co-operates with a spring- loaded idler roll. In another modification, the variation in feed rate is achieved by laterally oscillating a flexible guide tube 66, Fig. 7, for the electrode 30 by a double acting pneumatic cylinder 68.

Abstract: 1383047 Modulating light MARCONI CO Ltd 16 July 1973 [4 Aug 1972] 36487/72 Heading H4F An electro-optic cell comprises a layer of liquid crystal material contained between two electrode structures, the facing surfaces of the electrode structures each having been rubbed in a single direction with an ionic, polar or polymeric chemical compound such as to encourage orientation of the adjacent liquid crystal molecules parallel to the surface and to the direction of rubbing, the respective rubbing directions being parallel in the assembled cell. As particularly described, a nematic material having a negative dielectric anisotropy is used, being a single compound or a mixture, and the cell is disposed between polarizers respectively parallel and at 90 degrees to the common rubbing direction, whereby in the absence of an electric field across the layer, no light is transmitted through the second polarizer. When a potential difference (A.C. or D.C.) is applied between the electrode structures, the nematic layer scatters and depolarizes the light, some of which is then transmitted by the second polarizer. The electrode structures comprise conductive films, e.g. in a seven segment pattern, lying on a substrate and overlaid with a semi-insulating layer of silicon monoxide which provides the surface to be rubbed. The polarizers may be films cemented to the outer surfaces of the electrode structures and the light source may include a diffusing screen or an electroluminescent panel. The chemical compound with which the electrode structures are rubbed may be an ionic polar or polymeric material, including polyvinyl pyrrolidone; polyacrylamide; tetrabutyl-ammonium salts; indophenol blue; dioxan; 1,4- butanediol-diglycidyl ether; 4-nitrobenzylidene phenylhydrazone and 4-dimethylammocinnamylidene 2<SP>1</SP>, 4<SP>1</SP> dinitrophenylhydrazone.
