Abstract: 353,437. Rubber. ELECTRICAL RE. SEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Malm, F. S. ; 4201, West 21st Place, Chicago, U.S.A.) April 22, 1930, No. 12463. Convention date, April 30, 1929. [Class 70.] Vulcanizable bodies are joined by treating one or both of the contacting surfaces with a solvent cleansing material containing a vulcanizing agent and an accelerator, bringing the surfaces into contact and vulcanizing with or without heat, to form a tough vein at the joint. The invention is particularly applicable to the jointing of electric cables. Insulation is removed and the ends of the conductor 11 are scarfed, wired, and soldered. The old insulation 12 consisting for example of deresinated balata, deproteinized rubber, and Montan wax, is rendered plastic by heat (170-200‹ F.), and worked down in a taper extending farther than the middle of the joint. This is coated with a liquid consisting of 100 cc. of carbon disulphide, 3 gm. of sulphur, and 6 gm. of zinc butyl xanthate. The insulation on the other part of the cable is then worked into a taper overlapping the first taper, and its outer surface is treated with the same liquid. New insulation 21 is applied to restore the cable to its original thickness, the temperature necessary to render this material plastic being sufficient to form a vulcanized layer 17 at the joint. Another vulcanizable mixture described consists of 100 cc. of carbon disulphide, 2 cc. of dibenzyl amine, 3 gm. of sulphur, and 3 gm. of zinc butyl xanthate. Other suitable accelerators are zinc alkyl xanthates, and dithio carbamates, while mixtures of acetone and benzol, or carbon disulphide and carbon tetrachloride, are mentioned as alternative solvents.

Filed: 1928-05-01
Abstract: 295,702. British Thomson-Houston Co., Ltd., (Assignees of Hull, A. W.). Aug. 19, 1927, [Convention date]. Vacuum tubes. - The flow of electrons between a cathode and an anode is controlled by subjecting to a varying degree of illumination an electrode consisting of an insulating member which transmits light rays and carries a layer of light-sensitive material. As shown, the control electrode consists, of a helix 4 of quartz or optical glass having a monatomic coating of caesium or other alkali metal introduced from a metallic capsule 9 mounted on the support for the anode 2. The upper end of the helix is fused to the container and the lower end to a metal rod 11 embedded in the stem 6. The filament cathode 3 is of tungsten coated with caesium. The whole or a part of the inner surface of the container is coated with alkali metal. Light is directed on the end of the helix and traverses the electrode by reflection to the other end, thereby causing photoelectrons to be given up to the anode, and making the control electrode more positive, with the result that the more current passes between the filament and anode. A pair of filaments may be used, one being a few volts negative to the other and operating at a much lower temperature so as to supply a balancing current to the helix and vary the sensitiveness. In a modification a straight quartz rod coated with caesium, is surrounded by a helical filament which may be of the thorium-coated or Wehnelt type, but is preferably of caesium-coated tungsten operating at 800-1000‹ K. Instead of alkali metal, substances such as magnesium or calcium sensitive only to ultra-violet light, or substances such as barium oxide or compounds of sulphur sensitive to infrared light may be used.
