Title: Improvements in oleopneumatic suspensions having self-acting pumping
IPC: B60G11/30
Filed: 1964-11-24
Abstract: 1,084,438. Hydropneumatic suspension units. F. S. ALLINQUANT. Nov. 24, 1964 [March 28, 1964; Sept. 29, 1964], No. 47727/64. Heading F2S. A self-levelling oleopneumatic suspension element comprises a piston 4 which works in a liquid-filled cylinder 3 and which is carried by a first part 17 of a pump cylinder which has a suction valve 18, is secured to a second part 21 by a part spherical zone 22, and, with the part 21, co-operates with a pump plunger 13 which depends from a partition 6 having opposed damping valves 6a, 6b and communicating with a reservoir 1 containing compressed gas in a membrane 2. A port 12a in the cylinder 3, covered by the piston 4 in its medial position, is connected by a pipe 12 leading to a space 9 below the piston 4 in the cylinder 3 which is closed by a base cup 7 and a membrane 8 connected to the piston rod 5 and which communicates, through a pipe 10, with a tank 11 which contains liquid and is open to atmosphere. The pump plunger 13 has an axial bore 14 leading to an exhaust valve 15 in communication with the reservoir and a tapered lower end 16, which in the trim position of the suspension element just enters a head 25 which guides the pump cylinder part 21 in the cylinder 3 and carries a seal 26 axially spaced from the cylindrical part of the plunger 13. On compression when the plunger 13 co-operates with the seal 26 fluid is pumped into the reservoir 2 and when, on rebound, the piston 4 descends below the port 12 fluid from the upper end of the cylinder 3, which is at a superior pressure, is transferred to the lower space 9 through the pipe 12. Radial ports 14a in the lower end of the plunger 13 prevent suction noises as the plunger is withdrawn from the pumping cylinder. In a modification, Fig. 2 (not shown), the exhaust valve (115) at the upper end of the bore (14) in the plunger (13) leads directly into the upper chamber of the cylinder (3), the tapered end of the plunger co-operates with a deformable plastics sleeve (151) carried by the upper part (154) of the pump cylinder and having openings (152), and the lower part (155) of the pumping- cylinder is connected to the piston rod (5) by a spherical joint (129). The pipe (12) re-enters the cylinder at (12b) below which point piston travel does not permit transfer of liquid to the lower space 9. The valve (115) may be replaced by one leading to the reservoir. An alternative form of suction valve is described, Fig. 3 (not shown).

Title: Method of making moulded articles from polyurethane green stocks
IPC: C08G18/10
Filed: 1967-10-24
Abstract: 1,141,324. Moulding polyurethane. UNIROYAL Inc. 24 Oct., 1967 [18 Nov., 1966], No. 48173/67. Heading B5A. [Also in Division C3] Moulded polyurethane articles are prepared by mixing a liquid isocyanate-terminated polyurethane prepolymer with a liquid mixed diamine curing agent which has been obtained by condensing 2-chloroaniline, 2,5-dichloroaniline and formaldehyde in the presence of an acid, cooling the resulting liquid mixture to ambient temperature, storing the resulting green - stock at ambient temperature, and thereafter curing the green-stock at elevated temperature. The prepolymers are suitably heated to between 160 and 212 F., and the curing agent to a temperature sufficient to melt it and the two mixed. The mixture in a heated, flowable condition may be poured on to a casting surface to form a sheet which is allowed to cool before being cut into strips or broken up into granules, or may be poured into a cold mould to solidify in the shape of a "preform" having a shape roughly similar to the shape of the finally desired article. The strips or granules of green-stock may be moulded, or the "preform" pressed in a mould and finally cured by heating.

Title: Improvements in or relating to Circuit Arrangements for Starting Electric Discharge Lamps from Alternating Current Supplies
Inventor: WALSHE PETER ROBERT
IPC: H05B41/24
Filed: 1967-10-26
Abstract: 1,183,543. Supply systems for gas discharge lamps. GENERAL ELECTRIC & ENGLISH ELECTRIC COMPANIES Ltd. 7 Oct., 1968 [26 Oct., 1967], No. 48784/67. Heading H2H. Circuit for starting and operating a discharge lamp includes a series-resonant LC circuit in series with a voltage breakdown device and a suppressor inductance. In use, the breakdown device initiates oscillations for starting the lamp, and high frequency harmonics are suppressed by the inductance. In the circuit shown in Fig. 1, a ballast choke 3 operates as an autotransformer, the primary EF of which forms a series-resonant circuit with a capacitor 5. Initially, the capacitor is charged through a diode 6 from an A.C. source Vs until a Zener diode 10 breaks down and triggers a thyristor 8. Free oscillations at a frequency of the order of several kilocycles per second are now set up in the inductance EF & capacitor 5 until blocked by the thyristor 8 switching off. Radio frequency harmonics of the resonant oscillations also tend to arise, but these are suppressed by the low-value inductance 7. The thyristor 8 will continue to fire at intervals of one or more supply cycles until the lamp is started. The lamp discharge is then maintained by the supply Vs and the high frequency oscillations are short-circuited through the lamp. In a modification, Fig. 2 (not shown), the voltage breakdown device takes the form of a pair of anti-parallel Shockley diodes.

Title: Position determination device
IPC: G06F3/043
Filed: 1974-11-21
Abstract: 1484285 Position-finding SUMMAGRAPHICS CORP 21 Nov 1974 [5 Dec 1973] 50551/74 Heading G1G A position determining device comprises a sheet of magnetostrictive material, a transducer located at an edge of the sheet for inducing in the sheet a longitudinal-mode wave propagating perpendicular to the edge, a transducer movable over the sheet for detecting the wave, and means for digitally timing the wave propagation between a datum line and the movable transducer to determine the position of the latter with respect to the datum line. In the Fig. 2 embodiment a sheet 12 of magnetostrictive material is supported at its edges in a base 38. Material to be digitized is placed on a plastics support surface 40. Wires 16, 20 or coils near the sheet edges are pulsed in turn to launch longitudinal mode strain waves in sheet 12, propagating in the X and Y co-ordinate directions respectively. Magnets 22, 24, or permanent magnetization of sheet 12, enhance the magnetostrictive effect. Each wire may be spaced sufficiently from the nearest sheet edge that wave reflection at the edge enhances the "forward" propagation. The X wave reception by a pick-up coil 36 stops an X co-ordinate clockpulse counter which was started a given time after launching of the X-wave. This given time establishes a "margin", i.e. a distance origin. A delay allowing spurious reflections of the X-wave to decay follows stopping of the counter, after which the Y-wave is launched. Timing of the Y-wave propagation to coil 36 is similar to that of the X-wave and produces a Y count. On completion of the Y count a "data ready" signal is provided and both counts are transferred to a buffer store unless overflow of the counters has occurred. If overflow has occurred then the transfer is inhibited and an alarm is provided. The X and Y counts may be converted to analogue signals for displaying on a CRT the position of coil 36.  Fig. 7 shows an embodiment which provides three co-ordinate measurement. Wires 204, 206 launch X and Y waves as before and a vertically movable coil 220 launches a Z-co-ordinate wave down magneto-strictive wire 214. Coil 220 carries a pointer. The Z-wave is picked up by a coil 216 to stop a Z-co-ordinate counter. The X and Y waves are received by a dual-coil pick-up 224, 226 for stopping counters to determine the X-Y coordinates of coils 224, 226. The latter co-ordinates may be used to give an accurate indication of the X-Y position of wire 214, and to indicate the direction of the pointer. Details of timing logic circuitry for the above embodiments are given Figs. 5 and 8 (not shown). Reference has been directed by the Comptroller to Specification 1384313.

Title: Process and apparatus for the preparation of fluorolefines
IPC: C07C17/269
Filed: 1963-12-23
Abstract: Fluorolefins are made by pyrolysis of difluorochloromethane at 650-1000 DEG  C. in the presence of 0-25% by weight of steam, based on halomethane, wherein a stream of reactants is run through a preheated regnerator bed consisting of granular or lumpy particles of non-volatile, mechanically and chemically inert material, and the direction of flow of the reactants is periodically reversed so as to cool the regenerator bed in its respective entrance and exit zones and maintaining the central zone of the bed at operating temperature by heating until heat losses in the bed are compensated. Specified granular materials are alumina, magnesia, zirconia, titania or calcium fluoride.  It is preferred to heat the central zone of the bed to a temperature 20-50 DEG  C. above that of the reaction temperature.  The process is illustrated by reference to apparatus drawings (not shown).  In an example, tetrafluoroethylene, hexafluoropropene and octafluorocyclobutane are obtained as products with small amounts of fluoroform, trifluorochloromethane, difluorodichloromethane and trifluoroethylene by-products.
