Abstract: 488,437. Retractive switches. SIEMENS & GENERAL ELECTRIC RAILWAY SIGNAL CO., Ltd., GREEN, J. P., and RIDDLE, H. J. N. Jan. 26, 1937, No. 2320. [Class 38 (v)] [Also in Group XXXVIII] To differentiate in road-traffic signalling apparatus, between fast and slow vehicles, the member operated, e.g. pneumatically, from the road pad is connected resiliently with a slow-to-move contact-maker. Thus, in the type of contact box described in Specification 415,200, [Group XXXVIII], and as shown, the pressure-operated plate 7 fixed at 16 is connected by a spring 24 with a lever 23 pivoted centrally and provided at each end with a weight 26. If the plate is operated by a quickly-moving vehicle, no appreciable displacement of the lever results, but if the operation is prolonged due to the vehicle moving slowly, the lever rocks sufficiently to close a circuit either by ordinary contact abutment or by a mercury switch carried by the lever. Specifications 400,340, 406,993, and 487,398, [all in Group XXXVIII], also are referred to.

Filed: 1926-01-27
Abstract: 246,843. British Thomson-Houston Co., Ltd., (Assignees of Boyer, S.). Jan. 28, 1925, [Convention date]. Conducting-liquid switches -A liquid-expansion thermometer or thermally-operated switch contains, as the temperature - sensitive material, gallium or a gallium alloy which is free from impurities which would cause the meta to adhere to its container. Gallium free from metallic impurities is treated with hydrochloric acid to produce a protective film of chloride and is then placed in a bull 1 connected by a tube 2 tc a vacuum pump and by a tube 3 to a reservoir 4 connected to the stem 5 and bulb 6 of a thermometer &c. After a thorough exhaust the film of chloride is volatilized by heating, the metallic gallium remaining in a clean bright condition, free from oxide. The metal is then heated to redness to remove occluded gases, this process being repeated a number of times, after which it is transferred to the bulb 4 and the tube 3 is fused off. The required portion of the metal is caused to run into the bulb 6 and the thermometer is then placed in an oven with the bulb 4 projecting, and is heated several times to a temperature of 800‹ C. or higher, the stem of the thermometer being finally sealed off from the bulb 4. The thermometer is preferably made entirely of quartz but it may comprise a quartz bulb united to a glass stem as described in Specification 15695/15, [Class 56, Glass]. An alloy of gallium with another metal may be used, for example one containing 95 per cent of gallium and 5 per cent of indium.

Patent GB-823198-A (GB)
Title: Improvements in or relating to processes for the preparation of deuterium-containing carbon
IPC: G21C5/12
Filed: 1958-01-29
Abstract: Carbon containing deuterium is prepared by contacting solid carbon containing up to 10% bound H2 at an elevated temperature with a gas comprising D2 and/or D2 compounds which under the conditions yield D2 or exchange it with H2, e.g. deuterated gaseous saturated or unsaturated hydrocarbons.  The gas may be passed through finely divided (less than 5 mm. size) carbon heated to 500-1000 DEG  C. at atmospheric, reduced, or elevated pressure until at least 80% of the H2 present has been exchanged with D2.  The treatment may be effected in a fluidized system, or countercurrent in a vessel, where carbon is fed downwards and the gas enters through a distributer at the bottom. If the product still contains H2 it may be recycled, or passed to further vessels.  Any carbon may be treated, preferably microspheroidal, but should be free from B, S and N2.  The carbon may be degassed before treatment to remove hydrocarbon and/or water by subjecting it to a high temperature, e.g. 500-650 DEG  C., and/or high vacuum.  The carbon may be pretreated with H2 at the same temperature as, or 25-75 DEG  C. higher than, the subsequent deuterium contact to reduce formation of deuterated lower hydrocarbons.  This pretreatment may be effected in the same vessel by establishing a temperature gradient therein with the top of the vessel adjacent the carbon inlet being at a higher temperature.  The resulting C containing 0.5-5% D2 may be used as moderator, heat carrier, or reflector in nuclear reactors.  Specifications 798,029 and 798,030, [Group XL (a)], are referred to.
