Title: Method of manufacturing selenium rectifiers
IPC: H01L21/145
Filed: 1954-09-24
Abstract: 755,085. Selenium rectifiers. STANDARD TELEPHONES & CABLES, Ltd. Sept. 24, 1954 [Oct. 2, 1953], No. 27667/54. Class 37. A method of making selenium rectifiers comprises melting the counter electrode after the forming process and removing it and then replacing it by a porous counter electrode, e.g. by spraying. A first counter electrode layer of a Sn Cd alloy melting at 177 C., with e.g. a thallium content favourable to formation of a good barrier layer, is applied, e.g. by spraying, to the Se and the rectifier subjected to a forming process while the counter electrode is maintained molten. The counter electrode is then re-melted, if necessary,. and thrown off the Se plate for example by rotation thereof. After cooling a porous layer of the same basic alloy, containing less or no thallium is sprayed on the Se. The second counter electrode material may have a melting point lower than that of the first.

Patent GB-304372-A (GB)
Title: Improvements in and relating to frictional gearing and the like mechanism
IPC: F16H61/662
Filed: 1927-10-21
Abstract: 304,372. Thomson, B. Oct. 21, 1927. Variable-speed gearing.-In friction gearing, the power is divided between coaxial members 15, 15<a>, Fig. 1, from which it passes by non-planetary friction rollers 26, 26<a> to a member 8 with gear surfaces on both sides. End member 15<a> is fast on a driving-shaft 1 and end member 15 is connected to the same shaft through a helix of balls 16 by which frictional pressure is maintained. A spring coupling 22 is also arranged between shaft 1 and member 15. The double member 8 is connected by a drum 5 to a shaft 6 in line with shaft 1. In the form particularly described, the rollers 26, 26<a> are adapted to be tilted in unison to vary the speed. The friction surfaces on the members 15, 15<a>, 8 are therefore of torus form. The member 8 is cut away in the centre where is mounted a disc 11, Fig. 4, which is angularly displaced by a lever 51, Fig. 2, to vary the speed. Three rollers 26 are supported on three arms 27 of a spider 28, which is anchored by limbs 29 to a fixed casing 3. The spider 28 has a boss 30 projecting through the centre of control disc 11 and upon this is splined the spider 31 upon the arms 27<a> of which the rollers 26<a> are supported. The two spiders are thus interconnected and held fast with their arms in staggered relation. The rollers are not tilted by force, but by precession, which is a spiral creeping like the lateral motion of the front wheel of a bicycle. Rockably mounted on the end of each spider arm is the base 42 of a roller support. These bases are engaged at 46 by crank links 43, Fig. 4, all of which pass freely into holes 47 in the disc 11, the turning of which thus tilts the bases 42 in the plane of Fig. 1 about pivots 41. By inclined grooves 40, Figs. 4 and 1, and tenons 38, the outer small ends of the rollers 26, 26<a> are thus tilted circumferentially of the gear axis. Precession then comes in and the rollers are tilted automatically until outer blocks 36 are again in line with the axes of the supports 42. Alternatively, prior to a gear change a main driving clutch may be disconnected. The coupling springs 22, Fig. 4, then function to unscrew the ball helix 16, Fig. 1, releasing the end thrust. The rollers 26, 26<a> can then be tilted from the lever 51, Fig. 2, without opposition. As an alternative mounting for the rollers to effect precession, instead of the separate block 36 and cross slot 40, Fig. 4, the base 42 may have an extension projecting through an inclined slot in an outer supporting member.

Title: Core molding compositions
IPC: B22C1/24
Filed: 1957-08-08
Abstract: A core moulding composition is prepared by admixing a major proportion of an inert finelydivided solid with a minor proportion of a binding agent comprising an oil which is a polymer of an acyclic conjugated diolefin.  The core may then be formed and baked at 350 DEG  to 600 DEG F.  Specified diolefins are butadiene, isoprene, dimethyl butadiene, piperylene and methyl pentadiene while minor amounts of copolymerizable monomers, e.g. styrene, p-methylstyrene, dimethyl styrene, diethyl styrene, acrylonitrile, methacrylonitrile, methyl acrylate, methyl methacrylate, vinyl isobutyl ether, methyl vinyl ketone, and isopropenylmethyl ketone may also be present.  The oil may be treated with an oxygen-containing gas in the presence of a solvent, e.g. mineral spirits and a catalyst, e.g. an organic salt of cobalt, lead, iron or manganese, or it may be treated with an anhydride of an unsaturated dicarboxylic acid, before mixing it with the inert finely divided solid.  The solid may be sand or coke while the binding agent may also contain a vegetable drying oil.
