Abstract: 860,881. Thermionic valves. M.O. VALVE CO. Ltd. Nov. 27, 1959 [Nov. 27, 1958], No. 38312/58. Class 39(1). In a thermionic valve, preferably a beam tetrode, of the kind having a cathode 6, Fig. 1, with a planar emissive surface, an anode 21 and at least two grids-control grid 2 and screen grid 3-closely spaced from the cathode with the control grid-cathode spacing being 0.1mm the screen grid wires are supported at their ends by two ceramic bars 18, 19 which are secured to the beam forming electrode 4. The ceramic bars 18, 19 are of rectangular cross-section and act as supports for the screen grid wires and as spacers spacing them from the beam forming electrode 4.

Title: Improvements in or relating to gas turbine engines
IPC: F02C9/22
Filed: 1963-09-30
Abstract: 1,055,319. Fluid pressure servomotor control systems. BENDIX CORPORATION. Sept. 30, 1963 [Oct. 15, 1962], No.38431/63. Heading G3P. [Also in Division F1] An actuator for controlling the guide vanes of a gas turbine engine comprises a differential piston member 112, Fig. 2, having a ram portion 116 connected to the vanes and a piston part 114 slidable in a cylinder 110 to form chambers 120, 122 on opposite sides of the piston. The cylinder is bored transversely to form two axially aligned cylindrical bores 142, 144 which receive the ends of a control valve 146. Fluid pressure is supplied to the bore 142 and chamber 120 and the bore 144 is connected to exhaust. The valve 146 has bands 194, 164 which co-operate with the intersections of the bores 142, 144 and the cylinder 110 to control the supply and exhaust of fluid to and from the chamber 122. With the valve 146 in the neutral position the flow into and out of the chamber 122 provides a pressure to balance the constant pressure in chamber 120. The valve . 146 is actuated by movements of a rod 152 through a lever 156 which is pivoted at 166 to a member 168 urged by a spring 172 against a nut 154. The lever has a portion 160 engaging the valve 146 and a ball 176 at the other end of the lever engages a cam surface 176 formed on the piston 112. Movement of the rod 152 moves the valve 146 to vary the inlet and outlet to and from the chamber 122 thus causing movement of the piston and the cam surface 174 provides a feedback to move the valve 146 to its neutral position when movement of the piston ceases. The rod 152 is normally actuated manually by a throttle lever 78 through a cam 84 and lever 86. To retard the opening of the guide vanes when the throttle is depressed for rapid acceleration, the lever 86 may be actuated to override the action of the cam 84. As shown in Fig. 1 when the throttle 78 is depressed the loading of spring 87 of a speed governor is increased causing a switch 77 to be closed which opens a solenoid valve 71 to allow the compressor pressure to act on a diaphragm which operates lever 86 to move the valve 146 to provide vane closure. As the engine comes up to speed, the fly-weights of the governor cause the switch to re-open and the control is again responsive to the cam 84. To provide a braking effect from the engine when the throttle pedal is released and the engine is running at a sufficient speed, a pump 40 driven at engine or vehicle speed provides a pressure signal in line 76 which acts on a piston. A cam pivoted at 216 can engage the valve 146 when the throttle is in idling position and if the pressure from the pipe is sufficient, the valve 146 is moved against the spring loading 182 to cause the piston 112 to move the vanes 50 to a negative blade position whereby the flow of gas opposes the rotation of the engine. As shown the engine drives the wheels of a vehicle through reduction gearing 28, 30.

Abstract: 1,199,312. Polymerizing tetrafluoroethylene. DOW CHEMICAL CO. 22 Aug., 1967, No. 38689/67. Headings C3G and C3P. Tetrafluoroethylene is polymerized by feeding monomeric tetrafluoroethylene to a polymerization vessel and into contact with particles of a finely divided solid polymer consisting of at least a predominant amount by weight of tetrafluoroethylene and not more than a minor amount by weight of another ethylenically unsaturated fluoro compound copolymerizable therewith, suspended in water; withdrawing a liquid body comprising the polymer suspended in water from the vessel and then passing it through a field of high energy ionizing radiation of an intensity of at least 40,000 rads per hour and subjecting the polymer therein to irradiation with a dose effective to initiate polymerization of tetrafluoroethylene upon contacting and interacting the monomer with irradiated polymer; feeding a first portion of the suspension of the irradiated polymer to a filtering means and separating the polymer from the water, the water being passed from there to the vessel while a second portion of the suspension of the irradiated polymer is recirculated to the vessel where it is contacted with tetrafluoroethylene, the process being continued while feeding the tetrafluoroethylene to the vessel at a rate not substantially greater than it is consumed in the polymerization reaction. The polymer separated from the water may be contacted with additional tetrafluoroethylene and polymerization allowed to proceed until the rate of polymerization becomes negligible. Suitable polymers are homopolymers of tetrafluoroethylene and copolymers with hexafluoropropylene. The monomer may be linked to increase the parent chain length and/or grafted.

Abstract: 963,665. Dispensing liquids by gaseous pressure. CLAYTON CORPORATION OF AMERICA. Oct. 16, 1962, No. 39212/62. Heading F1R. [Also in Division F2] A tubular spout valve for a gas pressure dispenser comprises a rigid tubular stem 40, Fig. 3, haying an imperforate head 33, a port 36 into the stem, and a cylindrical portion 37 outward of the port, a resilient seal 29 and a spring 28 which is sufficiently deflectable to permit a portion 44 of reduced cross-section to be spacedly positioned in the seal aperture 31. This occurs when the stem is engaged by a hollow cast metal head 47 fitted with sealing pads 49, 51 and supplied with gas under pressure by a conduit 46. The centre 50 of the head may have an orifice to permit gas to flow into the container through the bore of the stem as well as through the space between the portion 44, which may be formed by two flats, and the seal aperture. Sloping areas 45 ensure that the spring can return the stem to closed position when gassing is complete. A detachable spout 38 limits downward movement of the stem during normal operation. In a modified construction and for use on a bottle the spring surrounds the portion of the stem above the seal and the stem is tilted instead of depressed to uncover the ports 36.
