Title: Improvements in or relating to sliders for slide fasteners
IPC: A44B19/26
Filed: 1954-02-01
Abstract: 781,272. Sliding clasp fasteners. CONMAR PRODUCTS CORPORATION. Feb. 1. 1954 [Sept. 17, 1953], No. 2991/54. Class 44 A slider, for slide fasteners of the type having two stringers with spaced interlockable elements, has front and rear wings spaced apart by a neck, the wings carrying inturned side flanges which with the neck define a Y-shaped internal channel between the wings, guiding means being formed in a wing beyond the end of an inturned side flange to prevent material being drawn into the channel by the interlockable elements. The guiding means is shown in the form of wedgeshaped grooves G, seen in section in Fig. 9, the grooves being set at an angle A of preferably 25 degrees. The walls R of the grooves are flush with the square cut ends 80, 82, of the inturned side flanges 76, 78. If, when the fastener is being closed, material is snared between the raised portion 86, Fig. 9, of the slider wing and the side of a moving element, the angle of the raised portion and the side wall R tends to guide the material outwardly away from the channel. If the material is not cleared in this way it will tend to bunch when it meets the side wall R and will pile up against an end, such as 88, of the inturned side flange thereby causing the slider to jam. This jamming action can be easily released by backing the slider and forestalls an inextricable jam. The mouth end 90 of the slider may have guiding means at its corners but is preferably chamferred as shown at 88.

Abstract: 701,747. Gas turbine plant. LUCAS (INDUS. TRIES), Ltd., J. Feb. 7, 1952 [Feb. 8, 1951] No. 3073/51. Class 110 (3). [Also in Group XXIX] In servo-operated liquid fuel control means for a jet-propulsion or gas turbine engine responsive to the pressure of the liquid fuel and to absolute blower or atmospheric air pressure, an ejector is provided to modify the action of the part responsive to blown or atmospheric pressure and a thermostatically or otherwise automatically operable valve controls the ejector. In Fig. 1 the delivery of the fuel pump, or a fuel throttle valve or by-pass valve is controlled by a spring- loaded servo-piston b under the control of a leak-off valve f carried by a spring-loaded lever g. The lever g is loaded by a piston k subject to the fuel pump delivery pressure in a line i leading to the burners and is also loaded by an evacuated elastic capsule m in a chamber n. The chamber n is connected to an ejector o adjacent the nozzle S thereof. The ejector is supplied with high velocity operating fluid which may be air delivered by the blower or liquid from the pump or other source. The flow of fluid to the ejector and hence magnitude of the reduced pressure acting on the capsule m is controlled by a valve p actuated through a lever r by a thermally responsive member q responsive to the temperature of the combustion chamber, the exhaust gas passage or other part of the prime mover. The valve p may alternatively be operated automatically by some other controlling factor e.g. speed. Thus the lever r may be operated by a centrifugal governor when the engine speed exceeds a predetermined limit. In Fig. 2, the servo-piston b regulating the fuel supply is controlled by a leak-off valve f operated by a piston l subject to the drop in fuel pressure across a throttle w between a fuel inlet 4 and a fuel outlet 5. The throttle u is loaded by a spring v connected to a lever 6 and is operated by a servo-piston w the opposite sides of which are connected by a restricted orifice y. The servo-piston w is controlled by a leak-off valve 3 carried by the lever 6 to which is also connected a spring 7. The lever 6 is operated by an evacuated elastic capsule m in a chamber n connected to an ejector o supplied by the blower. When the valve p operated by the heat responsive member is closed, the full blower delivery pressure is applied to the capsule m.

Title: Improvements in or relating to oscillating column combustion chambers
IPC: F23C99/00
Filed: 1964-01-28
Abstract: 987,079. Oscillating-column combustion chambers. L. HUBER. Jan. 28, 1964 [Feb. 23, 1963], No. 3626/64. Heading F1L. An oscillating-column combustion chamber comprises a passage connecting it with a fuel storage chamber which during operation is not in communication with the external air the rear wall of the combustion chamber being rearwardly and axially symmetrically recessed and in the recess the passage, which serves for the supply of fuel and starting air, is provided at its end adjacent the combustion chamber with an inwardly opening fuel feed, a conduit serving to supply operating combustion air opening into the combustion chamber independently of the passage. Fuel is fed through a float valve 29 to a fuel storage chamber 17. Air for combustion is supplied tangentially through one or more pipes 4. Starting air is forced by a blower, hand pump or the like through a pipe 27 into the top of the fuel chamber 17, entraining fuel vapour from the chamber and passing through a pipe 7 and apertured discs 9, 10 to the tapered inner end 2 of the combustion chamber 1. The reduction in pressure in the space 18 between the discs 9, 10 produced by the air flow, assisted by the air pressure exerted on the surface of the fuel in the chamber 17, causes fuel to flow from the chamber via a pipe 15 preferably containing an adjustable or exchangeable throttle 16, an annular chamber 14, bores 13, an annular chamber 12 and an annular passage 11, to join the air flowing through the space 18. The resultant mixture entering the combustion chamber 1 through the disc 10 is ignited by, for example, a spark plug or a glowing wire. The resultant explosion causes a back flow of gases through the discs 10, 9 and the pipe 7 into the fuel chamber 17. The flow of fuel is not interrupted, but the fuel drawn towards the space 18 returns through the pipe 7 to the chamber 17. Back flow through the air pipe 4 is prevented by a non-return valve (not shown). The flow of gases through the exhaust pipe causes the explosion phase to be followed by a phase in which the pressure in the combustion chamber 1 drops below atmospheric, causing the non- return valve to open to admit air through the pipe 4. In addition gases are sucked out of the fuel chamber 17 through the pipe 7 and discs 9, 10, and fuel enters the gas flow as previously described and is torn into fine droplets at the preferably sharp exit edge of the aperture of disc 10. The cycle now repeats, a supply of starting air no longer being required. The operation is ended by closing a fuel valve 31. Cooling fins 3 may be replaced or supplemented by a cooling jacket which may be used for pre-heating the combustion air. Instead of protuding into the combustion chamber 1 as shown, the end of the nozzle 8 may be flush with the rear wall of the combustion chamber or may lie behind it. The aperture of disc 10 is preferebly smaller than that of disc 9.
