Filed: 1973-02-19
Abstract: 1451641 Discharging from an aircraft M L AVIATION CO Ltd 19 Feb 1974 [19 Feb 1973] 8061/73 Heading F3C [Also in Division F2] An ejector release unit for releasing and projecting an object from an aircraft has a throttle which can adjust the pressure applied to a telescopic ejection gun of the unit. A throttle member 2, Fig. 1, is located in a housing 4 of an ejector release unit 6, has an axial bore 8 which communicates with a source of pressure generated by the firing of an explosive cartridge via a passage 30 and with radial passages 10, Fig. 4, which are in the throttle member 2 and have different diameters, and is rotatably mounted in a member 12, Figs. 1 and 3 which, having a screwthread 14, is secured into the housing 4. The member 2 has parts 16, 18 the former being of erosionresistant material and the latter having an extension 20 received in a bore 22 of the member 12. A spring 26 is positioned in an enlarged portion of the bore 22 and is compressed by a nut 28 screwed onto the end of the extension 20 of the part 18 of the member 2, this causing a shoulder 24 of the member 12 to be urged against the part 18. The nut 28 may be adhered to the extension 20 and may serve as a knob for rotating the member 2 to align the required radial passage 10 with a passage (not shown) which leads to an ejection gun (not shown). In another embodiment the throttle member 2 has passages 32, Fig. 5 which extends across the diameter of the member 2 and have different diameters. The throttle transfers pressure from a breech 34, Fig. 2, of an ejection release unit, to a passage 36.

Title: Improvements in the manufacture of curved lengths of plastic pipes and similar tubular bodies
IPC: B29C53/60
Filed: 1957-03-14
Abstract: 819,831. Rigid or semi-rigid tubular members. VICKERS-ARMSTRONGS (AIRCRAFT) Ltd., and WILLIAMS, R. Jan. 23, 1958 [March, 14 1957], No. 8451/57. Class 99(2). A process of manufacture of a curved rigid or semi-rigid plastic tubular body consists in forming a flexible core to the desired shape and holding it in such form, treating the core with a preparation adapted to prevent subsequent adhesion of the pipe to the core, applying a liquid resin impregnant to the outer surface of the core, wrapping or clothing the coated core in a fibrous fabric reinforcement including a liquid resin impregnant applied during the wrapping or clothing operation or previously, heating the wrapped core to a temperature and for a duration such as will polymerise the liquid resin impregnant and subsequently withdrawing the core from the tubular body. As shown the core A is bent to the desired shape and held in the jig B. The core is then coated with a silicone grease wax, polyvinylalcohol or the like. After this a liquid synthetic resin impregnant (e.g. epoxide, polysulphide or polyamide resin) is applied to the core. The next step consists in wrapping a tape braid or flat woven piece of glass-fibre cloth or glass fibre rovings about the core as indicated at E until the full length of the core has been covered. Alternatively a tubular woven sheath of such reinforcement material may be drawn over the core before it is set up in the jig. The reinforcement material may have been impregnated with the liquid resin before the wrapping or clothing operation and/ or liquid resin impregnant is applied as the wrapping or clothing operation proceeds and a further liberal application of resin may be made after the wrapping is complete. The assembly is then stoved or otherwise heated to a temperature and for such duration as will effect the polymerisation of the resin. Subsequently the core is withdrawn. The core may be made from natural or synthetic rubber or derivatives thereof or polyvinyl chloride or a flexible metallic tubing.

Abstract: 127,409. Newton & Wright, and Litchfield, T. May 30, 1918. Shutters. - In shutters having two oppositely-moving blades geared together and a blade-actuating member controlled by a releasing-lever, the bladeactuating member E is pivoted, has an arm G which directly engages a projection C<4> on one of the blades D to separate them, and has a spring H directly acting upon it to effect its operative movement. The spring H is secured to an arm E' projecting from the pivot of the member E in an opposite direction to the arm G, and the arm E<1> normally engages a projection C<5> on the blade D' to hold the blades in the closed position. The shutter is set by rotating the member E in a clockwise direction by a handle F external to the casing, until the arm G, which is resilient, slides up, over, and snaps behind the projection C<4>, a catch L' at the end of the releasing-lever L then engaging, under spring action, in a notch E<3> and holding the member E with the arm G and projection C' in contact. When the release is operated, the member E is pulled round under the control of a dash-pot J, by the spring H, and the arm G presses on the projection C<4> and separates the blades. The end of the arm then slides past the projection C' against its side and permits the blades to close under spring action. The piston of the dash-pot is connected by a link K to an arm E<2> which projects vertically downwards when the shutter is set, the arrangement being such that the control of the dash-pot diminishes as the movement of the member E progresses. The releasing-mechanism may be of any convenient form permitting time, bulb, and instantaneous exposures, and a needle valve J<2> may control the dash-pot in accordance with the exposure.
