Title: Piston Arrangement for Dual Circuit Brake Systems.
IPC: F16D65/18
Filed: 1967-11-13
Abstract: 1,156,078. Vehicle braking cylinders. ALFRED TEVES G.m.b.H. 13 Nov., 1967 [16, Nov., 1966], No. 51506/67. Heading F2F. An actuating cylinder for a dual-circuit braking system has a stepped piston 1 (Fig. 1) with a second pot-shaped piston 2 sliding on the stem of the first, the two pistons having the same external diameter, one pressure line 6 being connected between the second piston 2 and the casing 7, and the other pressure line 5 being connected via a double-acting valve 4 to the space between the two pistons. If the first line 6 fails, the piston 2 will be forced against the casing and the pressure in line 5 will move the inner valve member 17 to the right to close a bore 9 (Fig. 2). The whole valve member 11 then moves to the right against a spring 16a unseating the edge 11a so that fluid passes through longitudinal grooves 10 into the chamber 3 (Fig. 1) to displace the piston 1 to the left and apply the brakes. On release, fluid from chamber 3 returns partly by the same path and partly via longitudinal grooves 15 in the inner valve member 17 and in the valve stem 14. If there is no pressure in line 5, movement of piston 2 displaces the inner valve member 17 to the left against a spring 16 until it seats at 12. The chamber 3 is now sealed and both pistons move together. If the pressure in line 5 fails after application, the pressure in chamber 3 seats the inner valve member 17 as before. On release, the pressure in chamber 3 is relieved and the inner valve member 17 is unseated by the spring 16. The brake reservoir preferably contains an indicating device to show when the liquid level or pressure has fallen below a particular value. Modifications.-The spring 16 may be located at the end of the valve stem 4 (see 20 in Fig. 1). The inner valve member 17 may be without the longitudinal grooves 15, in which case pressure relief in chamber 3 occurs by displacement of this member towards the seal 12. The valve stem 14 may be a clearance fit instead of having longitudinal grooves.

In Fig. 1, switch member W in the position shown, derives shuttles from conveyer string F to reception chamber E, after braking the shuttle by means of air cushion formed when the member W is seated against sealing surface D. Slightly to the left of sealing surface D is the position of member W for transit of shuttles through the station along conveyer string F. Further left is the position of member W to transfer shuttles from string F to string FA. Pivoting of member W is controlled by contact fk. Fig. 2 shows an alternative embodiment with two mutually independent switching members R and WK. Member R is a tube section which may be moved out of the position shown such that the diverting section A is in position to deflect shuttles arriving along tube F into conveyer string FA, with member WK in the position shown. Pivoting of member WK to rest against the left-hand projection V deflects shuttles from tube F via pendulum valve K to receiving chamber E. When member R is in this outward position, shuttles may be inserted in this tube section for despatch.

Title: Television synchronising pulse generating system

Filed: 1974-12-19
Abstract: 1498420 Television; synchronizing signals QUANTEL Ltd 11 Dec 1975 [19 Dec 1974] 54882/74 Heading H4F An advanced mixed sync. signal (i.e. one where some or all of the equalizing pulses are replaced by broad, field sync. pulses) is produced from a standard sync. signal by detecting the first equalizing pulse, using this detection to trigger, via a delay, a broad pulse generator, and combining the generated broad pulses with the standard sync. signal. As described, detector 13 recognizes the first equalizing pulse and triggers a monostable 17 having an output pulse lasting for the duration of the equalizing pulses, i.e. 8¢ lines in the NTSC systems (Fig. 1a, not shown). Monostable 17 inhibits the equalizing pulse detector and also triggers a generator 23 which activates the broad pulse generator 26 after a delay of ¢-2¢ lines, preset at 21. In an NTSC system a delay of 2¢ lines results in broad pulses being generated ¢ line ahead of those in the incoming sync. signal and a delay of ¢ line advances the generated broad pulses by 2¢ lines (Fig. 1, not shown). Monostable 17 further provides an enabling signal to AND gate 31 so that broad pulses may only be generated during the 8¢ lines following the first equalizing pulse. The generated broad pulses are mixed with the incoming, standard sync. pulses at OR gate 35 to produce, at output 42, the advanced mixed sync. signal, which signal may be used to drive a video tape recorder having a timebase corrector which introduces a delay of from ¢-2¢ lines in the video output.

Title: Propulsion unit propellant systems
IPC: F02K9/58
Filed: 1971-11-26
Abstract: 1369466 Rocket propulsion systems MESSERSCHMITT-BOLKOW-BLOHM GmbH 26 Nov 1971 [4 Dec 1970] 55083/71 Heading F1J The invention relates to a propulsion unit propellant supply system in which a propellant is passed through a catalyst whereby decompositon gases are genereated, flow of propellant being controlled by means of a multi-part capillary body, one part of the capillary body being movable so as to control the flow passage. In Fig. 1 monopropellant is stored in a container 1 which is lined with capillary material 2, the container projecting into a chamber 3. Two diaphragms 4 and 5 extend across the chamber and define therebetween a chamber 8, the diaphragms supporting a capillary body 2b and a catalyst 6. As shown the capillary body 2b is spaced from the capillary body 2a in the container 1 by a distance a so that no flow of propellant can take place. When the body 2b moves downwardly to contact the body 2a propellant flows by capillary action through the bodies 2a 2b to the catalyst 6 whereby it is decomposed, the gases passing from the chamber 8 through valve 10 to the gas container 11. Gases pass from the container under control of valves 13 to the control nozzles 14. The diaphragm 5 acts as a control diaphragm and positions the capillary body 2b in dependence on the gas pressure within the chamber 8 and on the opposing loading of the spring 7. The pressure in the chamber 15 below the diaphragm 4 is equalized with that in the propellant container 1 by means of a duct 16 and the pressure above the diaphragm 5 is equalized with ambient pressure by means of openings 18. In a second embodiment flow of propellant is controlled by a slide valve member of capillary material. Two systems are provided for flow of two propellants each of which is decomposed, the decomposition gases from the two catalyst chambers passing to a single reaction chamber from which gases discharge through a nozzle.
