Title: Improvements in and relating to the coating of tubes during the manufacture of light sources
Inventor: GUTHRIE DAVID GRAHAM
IPC: C09K11/02
Filed: 1965-08-03
Abstract: A method of coating the inner surface of a translucent tube for use in a self luminous light source wherein a phosphor coating is excited to luminescence by a gaseous radio nucleide, comprises dissolving or suspending a binder in a liquid medium, for example, orthophosphoric acid in acetone or ether introducing the liquid into the tube to form a body of liquid supported therein by surface tension to block said tube, propelling the body of liquid through the tube at a speed sufficient to coat the tube with the liquid by air under pressure, the air at the same time evaporating the liquid from the deposit, drying the deposited coating, adding excess of a phosphor, e.g. zinc sulphide, removing surplus phosphor and baking the tube.ALSO:A method of coating the inner surface of an open ended tube with an adherent material comprises introducing a body of liquid medium containing a coating material in solution or in suspension into the tube, whereby the surface tension of the liquid is chosen such that the body is not separated from the tube propelling the plug through the tube by a jet of pressurised air at a speed sufficient to coat the tube with liquid and evaporate the liquid. In a preferred embodiment, the inner surface of a glass tube is coated with orthophosphoric acid using a solution thereof in acetone or ether, the resultant coating being dried and a phosphor, e.g. zinc sulphide applied thereto, the coated tube being used as a self-luminous light source wherein the excitation is effected by a gaseous radionucleide.

Filed: 1969-07-02
Abstract: 1276187 Coil springs DANFOSS AS 2 July 1969 [10 July 1968] 33463/69 Heading F2S The force which a coil spring 8 exerts on a member 2 is adjusted by a screw 13. The spring has sections 9, 10 each of constant diameter, the section 9 being oflarger diameter and larger pitch than the section 10, and the free end of each section being formed with an abutment portion 11, 12. Normally the section 10 clamps the adjusting screw 13. However, on rotation of the screw in either direction one or other of the abutment portions 11 and 12 registers with a corresponding abutment (i.e. on the member 2 or a housing 1). Continued rotation of the spring then increases the diameter of the section 10. The clamping action of the spring ceases and allows the screw to be moved in or out as the case may be to alter the force of the spring on the member 2.

Abstract: 925,984. Gas turbine plant. CATERPILLAR TRACTOR CO. Sept. 19, 1961, No. 33466/61. Class 110 (3). [Also in Group XXVII] An exhaust gas turbo-supercharger is provided with means whereby the exhaust gases flow through a passageway of small area so as to create high velocity when the engine is operating at relatively low speeds, and through a passageway of larger area so creating a relatively lower velocity when the engine is operating at higher speeds. The unit shown comprises a turbine 14 and compressor 15 mounted on a common shaft, the turbine being driven by exhaust gases from engine manifold 23 which pass to the turbine inlet 17 and are directed on to the rotor blades by guide blades 25. The turbine inlet is divided into two portions by a partition 26 and the guide blades are also divided by a partition 27. At relatively low engine speeds the exhaust gases flow as indicated by full lines into the left-hand portion of the turbine inlet and through the left-hand portion of the inlet guide blades. At higher engine speeds, the valve 30 is opened and a portion of the exhaust gases then flows as indicated by broken lines into the chamber 29 and passes into the righthand portion of the turbine inlet and through the right-hand portion of the guide blades. The valve 30 is actuated by means of a piston 31 to which fluid under pressure is supplied through line 34. The operating fluid may be lubricating oil, the pressure of which is dependent upon engine speed. In a second embodiment, the exhaust gases flow directly from the inlet volute on to the rotor blades, no guide blades being provided. The inlet volute is divided by a partition as in the first embodiment.
