Abstract: 356,292. Fluid-actuated valves. METROPOLITAN-CAMMELL CARRIAGE, WAGON, & FINANCE CO., Ltd., Metropolitan Road, Saltley, Birmingham, TRIST & CO., Ltd., R., 56, Victoria Street, London, and BAYLISS, A. V., Metropolitan Road, Saltley, Birmingham. June 10, 1930, No. 17773. [Class 135.] Valves controlled by pilot or relay valves.-A stop valve for use in connection with drop-stamps, steam hammers and like machines is actuated by fluid pressure under the control of a shuttle auxiliary valve operated when the main controlling lever is moved into the normal rest position. The auxiliary valve comprises a lining b readily removable from the upper part of a cylindrical casing a and divided by a partition e of substantial thickness into two spaced chambers c, d connected by an axial bore f having at each end seatings for the alternate engagement by valve members o, o<1> on a longitudinally movable spindle n. The upper chamber is closed by a removable flanged head g bored to receive the fluid inlet pipe j while the lower chamber is closed by a flanged head l provided with a stuffing box m through which the valve spindle passes. The gland of the stuffing box is held against rotation by a pin or projection r engaging a recess in the casing. The exhaust pipe w passes through a clearance hole in the outer casing and is threaded into the wall of the lower chamber while a pipe x leading to the main actuating cylinder passes through a similar hole in the casing and is threaded into the partition e. The valve member o is normally held against its seat by a spring p bearing against a head q and is moved away by a plunger engaging a buffer comprising a spring housed in two telescoping tubes s, t connected by pins u engaging slots v.

Abstract: 813,665. Sealing electric lamps. SYLVANIA ELECTRIC PRODUCTS Inc. June 4, 1957 [June 27, 1956], No. 17781/57. Drawings to Specification. Class 39(2) In a method for sealing and tipping off the exhaust tube of a glass envelope filled with gas at a pressure above atmospheric e.g. gas-filled electric lamps such as photo flash bulbs, a portion of the tube is heated sufficiently to soften the glass but not to rupture it by the internal gas pressure, the softened portion is pinched closed, and the tube below the pinch is then exhausted and heated to cause it to flow into a gas tight seal, being finally tipped off. During the heating below the pinch, the tube may be stretched.

Title: Improvements in the manufacture of hollow reinforced concrete products
IPC: B28B23/22
Filed: 1948-07-01
Abstract: 653,769. Concrete pipes. FRANJETICH, Z. July 1, 1948, No. 17789. Convention date, July 5, 1947. [Class 99(ii)] [Also in Group X] Prestressed concrete pipes are made by securing concrete bars having tensioned wire reinforcement, around the expansible core of a mould, winding a wire around the bars and core to form a transverse reinforcement, tensioning the latter by expanding the core and then applying concrete to embed the reinforcements and form the walls of the pipe. The apparatus consists of a mould having an expansible core, shown in Fig. 4. A number of T- section bars 4 are arranged symmetrically around a rod 1, provided at the ends with left and right hand threads. The ends of bars 4 bear on cones 2 which are engaged on the threads on rod 1 so that turning the rod causes the cones to approach one another and the bars 4 to spread apart. Concrete bars 5 having tensioned, "twisted pair" wire reinforcements, are laid on the core so as to bridge the spaces between. the bars 4 and a wire reinforcement 6 is wound around the bars. The cone is then expanded to produce the required tension in wire 6 and the assembly inserted into a cylindrical outer shell. Concrete is poured into the annular space between the core and shell to form the pipe which is removed after setting by contracting the core.

Abstract: 472,561. Shock - absorbers. LIBERATORI, U. June 26, 1936, No. 17797. Convention date, June 26, 1935. [Class 108 (iii)] In a constantly-acting frictional shockabsorber of the internally-expanding shoe type, for vehicle suspensions, a drum 8 is oscillatable, by links 12, 12<1> connected to the vehicle spring, on a stationary spindle 3 projecting from an end plate 1 which is fixed to the chassis and carries upper and lower adjustable cams 5, 5<1> adapted to act on the shoes 4. As shown, the lower cam 5<1> is adjustable, in order to vary the friction between the shoes and the drum, by means of an arm 15, the position of which may be varied by a screw stop 18 or by a flexible cable 16 operable by the driver, while the upper cam 5 is adjustable, for example, by a nut 14, to compensate for wear of the fibro-metallic shoe linings 7. The cables 16 of a pair of shockabsorbers may be connected to arms 26, Fig. 5, projecting from a nut 25 mounted on a screw-threaded spindle 22 rotatable at its lower end in a bearing 23, the arms sliding in fixed guides 24 so that manual rotation of the spindle 22 by a hand wheel 32 causes vertical movement of the nut and thus varies the frictional resistance offered by the shockabsorbers. A wire 28 connects the nut with a spring-rotatable cylinder 29 which is marked in order to indicate the degree of adjustment required for various vehicle loads.

When the concrete has set the trench is extended in either direction and the adjacent device 11 is moved to the farthest end of the trench extension. A further cage of bars 19 is then inserted so as to overlap the ends 14 of the first cage and engage with the slots 13 of the re-sited device 11. Concrete is then poured as before to fill the space between the existing wall-section and the re-sited device. This procedure is repeated as necessary. Spring-loaded strips 16 on the ends 14 close the grooves 13 to keep them free of concrete. At least one strip of sheet-metal 20 matching the profile of the edge 21 of the existing wall-section guides the cage 19. While the concrete is setting the devices 11 are reciprocated vertically by hydraulic jacks (not shown) to prevent adhesion.

Abstract: 1499408 Microwave amplifiers INTERNATIONAL STANDARD ELECTRIC CORP 30 April 1975 [30 April 1974] 18044/75 Heading H3W A microwave amplification system comprises parallel amplifiers 8, 9, Fig. 1, and input and output couplers 1, 2 whereby in normal operation, the amplifiers work in parallel but if a circuit 15 deduces from measurements made at 10, 11, 12 and 13 that one amplifier is defective, it switches off that amplifier and alters the phase shift introduced at 101, 102, 121, 122 to switch all the power through the working amplifier. The coupling circuits comprise 3 dB hybrid junctions 100, 103 and ferrite phase shifters 101, 102. Normally the paths through 102 and 122 are #/4 longer than those through 101 and 121 so that an input at E is divided into equal parts for amplifiers 8, 9 and equal signals applied to hybrid junction 120 feed an output antenna S. Opposite 45 degree phase shifts are applied to 101 and 102 to direct the whole signal to one amplifier or the other and to 121, 122 to couple the operative amplifier to the antenna. When the amplification system has several stages in series, couplers may be provided between each stage to cut out any defective amplifiers. To minimize the effect of reflections from the antenna, the length from amplifiers 8 and 9 to the input of coupler 12 differs by #/4.
