Title: Improvements in or relating to liquid hydrocarbon fuel burning devices
IPC: F23D11/44
Filed: 1933-07-18
Abstract: 427,465. Starting vapour - burners. JACKSON, L. MELLERSH-, 28, Southampton Buildings, Chancery Lane, London.-(Coleman Export Corporation ; 5133, West 65th Street, Chicago, U.S.A.) July 18, 1933, No. 20301. [Class 75 (i)] For initially heating a vapour burner, a tank 1 containing liquid fuel under air pressure in contact therewith is provided with a liquid fuel conduit 20 leading from the tank and having a liquid fuel inlet 29 below the liquid level in the tank, an air passageway 25 within the tank having its inlet 24 above the liquid level and its outlet discharging into the liquid fuel conduit near the inlet end, and a shut-off valve 16 in the liquid fuel conduit, the air passageway being of relatively small crosssectional area so that there will be a frictional retardation of the air flow through the air passageway 25 when the valve 16 is initially opened to enable the air pressure acting on the surface of the liquid to be momentarily greater than that in the air passageway to ensure that the liquid in the conduit is raised to the burner, the air from the passageway mixing with the fuel to form the mixture for initial starting. A tube 22 fits around the tube 20 and forms the passageway 25. A stem 30 extending from the valve 16 projects through the inlet 29 to restrict the flow of liquid when the vaporizer is initially heated by the fuel and air mixture. Afterwards, by further raising the valve 16 and stem 30, the inlet 29 is fully opened so that liquid only flows up the tube 20, the discharge of air from above the fuel thus ceasing. The shut-off valve may operate at right-angles to the stem controlling the fuel inlet, and have a conical part against which a rod carrying the stem is pressed by a spring. British Specification 298,221, [Class 75 (i)], and U.S.A. Specifications 1,886,420 and 1,893,598 are referred to.

Abstract: 586,940. Welding electrode holders. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 25, 1944, No. 20728. Convention date, Oct. 25, 1943. [Class 39 (iii)] In a gas-arc welding torch, gas supplied through a tube 22 is prevented from escaping from the top of the nozzle 4 by means of a valve 26, so that an electrode 2 can be used until it is only just long enough to be held by jaws 18 which are made to grip the electrode by tightening a screw 15, as described in Specification 448,231. By pressing part 28 against a spring 27, holes 29, 30 are aligned and a longer electrode can be inserted, the spring- pressed valve 26 forming a gas-tight fit about the electrode. In a modification (Fig. 4, not shown) a rotary valve member is opened and closed by rotating its operating head to adjust the hole therein relative to' the electrode passageway in the nozzle. Two nozzles are mounted on a handle to form the complete torch, the gas supply tube to one nozzle having a looped resilient portion which enables one electrode to be adjusted relative to the other.

Title: Improvements in means for and methods of altering the frequency of piezo-electric crystals
IPC: H03H3/04
Filed: 1949-08-15
Abstract: Piezoelectric crystals are coated with silicon dioxide or titanium dioxide or a mixture of both, by treatment with a coating composition.  For a silica coating, tetraethyl-ortho-silicate is dissolved in a mixture of ethyl alcohol and ethyl acetate to which is added hydrochloric acid, hydrobromic acid, formic acid or chloracetic acid.  Other water miscible solvents may include butyl alcohol, iso-propyl alcohol and monethyl ester of monoethylene glycol.  The thickness of the coating is determined by the proportion of tetra-ethyl-ortho-silicate.  A coating of titanium dioxide is produced from a solution of titanium tetra-chloride or tetra-bromide in ethyl alcohol to which may be added water miscible solvents such as the lower alcohols, monethyl ester of monoethylene glycol and its derivatives, and 1-4-dioxane.  A mixed coating is produced by using a composite solution containing both the silicon and the titanium compound.  After coating with the solution, the element is heated in an oven to remove the solvent.
