Title: Improvements in or relating to motor vehicles having a pneumatic or hydro-pneumatic suspension system with a circuit-closing device
IPC: B60G17/04
Filed: 1960-07-25
Abstract: 939,414. Pneumatic suspension circuits closing devices. REGIE NATIONALE DES USINES RENAULT. July 25, 1960 [July 29, 1959], No. 25844/60. Class 108(2). A circuit closing device of a pneumatic or hydropneumatic suspension system is characterized in that it is opened by a member responsive either to the depression existing in the engine manifold or to the engine lubricating oil circuit pressure. A suspension air reservoir 3, Fig. 1, communicates through orifice 25 with outlet 4 to the suspension system. A spring loaded valve 22 normally closes the orifice when the engine is stationary or ticking over but when the engine speed increases the manifold depression acts through communicating pipe 18 on the lower surface of diaphragm 13 against the force of spring 20 to lower the attached control rod 17 which opens valve 22 allowing communication between the reservoir and suspension system. When the manifold depression falls either at full throttle or when the engine stops the valve closes again. Fig. 3 shows a device controlled by the lubricating oil circuit pressure which acts on the upper face of a piston 30 against a spring 34 to lower rod 17 and hence open the valve between the reservoir and suspension system. The circuit closing device may also be fitted between a pneumatic spring and its exhaust to limit the minimum spring pressure.

Title: Improvements in or relating to balanced electric protective arrangements for alternating current systems and relays therefor
IPC: H02H3/30
Filed: 1923-10-16
Abstract: 227,523. Reyrolle & Co., Ltd., A., and Leeson, B. H. Oct. 16, 1923. Cut-out arrangements; automatic circuitbreakers.-In balanced protective systems of the Merz-Price type, the relays or circuit-breakers are rendered immune from the effects of disturbances external to the protected section due, for example, to an arc fault between phases or to earth and resulting in high frequency currents, by tuning the relays or the pilot circuit containing them so that they will be responsible only to a predetermined range of current and frequency. As shown in Fig. 1, the relays at the two ends of the pilot wire system are themselves tuned by a condenser J and inductance H connected across them. Alternatively, the pilot wire system may be tuned by including in series with it a condenser and an inductance. The relay may be mechanically tuned. In Fig. 3, a reed K tuned to the required range of frequencies is set in motion by the current in the coil D, and, when its amplitude becomes sufficient, it strikes a spring latch L and releases the contactmember F<1> of the relay. Instead of a reed, a spring-controlled balance-wheel may be used. In the arrangement shown in Fig. 5, the tuned reed K, at a certain amplitude, completes the circuit of a holding magnet O<1> and the circuit of the relay is completed at G. Specification 200,876 is referred to.

Title: Method of manufacutring composite building slabs
IPC: B28B23/02
Filed: 1971-04-19
Abstract: 1338449 Building panels; elevated floors; ceilings MERO AG 19 April 1971 [30 Jan 1970] 25956/71 Headings E1B and E1W [Also in Division B5] A composite load-bearing building slab is formed from a preformed tray of relatively high tensile strength and elasticity modulus into the cavity of which is poured a material of relatively low tensile strength and elasticity modulus, in an amount which corresponds approximately with the volume of the cavity, this material being at least partially consolidated and, during or after consolidation, the volume being adjusted to that required to fill the cavity. The filling material may, e.g. be concrete, cement-bonded mineral substances, synthetic resins which may have various fillers or may act as binders for fibrous materials, wood fibres and cement or asbestos cement. The tray may be of steel, which may be galvanised or have a rough protective layer and/or a plastics layer; light metal alloys; or pressure-mouldable plastics such as glass-fibre reinforced synthetic resin. The tray preferably has holes or pressed out tabs for anchorage and may be placed on a vibrating surface to consolidate the filling, which is then levelledoff with a scraper; or it may be placed in a mould having holes in its base corresponding to those in the base of the trough and slightly overfilled, the filling then being compressed to consolidate and level it and the surplus being expressed through the holes. Alternatively the tray may be slightly under-filled and then consolidated by bringing a plunger level with the top and forcing plugs up through the holes in the base, these being withdrawn subsequently to leave cavities in the slab. In other embodiments the tray is formed without holes or tabs, these being produced by pressure tools at the consolidation stage. The tray may be flanged and a cover plate, of the same material provided. Floor elements for a double floor are provided with precisely-located anchorage holes for the dowels of foot supports (Fig. 9, not shown). Ceiling slabs for a 3-dimensional lattice (Figs. 10 and 10a not shown) have anchorage screws pressed up through the bottom of the tray, and peripheral flanges which enable the elements to be secured by screws to the support plates of modal element.

Title: Improvements relating to electrical circuits for producing oscillations of non-sinusoidal wave form for use, for example, with cathode ray devices
IPC: H03K4/43
Filed: 1932-05-26
Abstract: 401,634. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd., Hayes, Middlesex, and MANIFOLD, M. BOWMAN-, Heathcot, Worplesdon Station, Surrey. May 26, 1932, No. 26019/33. Divided on 402,134. [Classes 40 (iii) and 40 (v).] Relates to the production of currents of saw-toothed wave-form for scanning in television receivers of the cathoderay-oscillograph type. The currents are controlled and synchronized by means of impulses generated as described in Specification 402,134. These impulses have been transmitted as subcarrier impulses, and after demodulation of the carrier the sub-carrier is applied to terminals 13, 14. The sub-carrier is demodulated by valve V5, and the impulses which control the line scanning-coils 22 are separated by condensers 15, 20 from those which control the frame scanning-coils 18. So long as valve V6 is blocked, condenser 16 charges up slowly through resistance 17, but when a frame scanning-impulse arrives condenser 16 discharges rapidly through the valve. Thus a saw-toothed grid-voltage is applied to valve V7, and the frame scanning-coils 18 carry a saw-toothed current in view of their impedance being low in comparison with that of the valve. In the case of the line scanning- impulses, however, the inductance of the coils 22 cannot be neglected, and a wave-shaping system 26, 27, 28 is employed. The line scanning-impulses pass through valves V1, V2, V3, as described in Specification 402,134. Oscillations are set up in the tuned circuit 3, 4, 21 ; valves V2, V3 are biased so that only the peak of the wave is passed ; and the time constant of the coupling between them is made small, so that sharp short impulses are applied to valve V3. So long as valve V3 is blocked, condensers 26, 27 (of which 27 is larger than 26) charge slowly through the resistances shown, but when an impulse arrives the condensers suddenly discharge through the valve. The output voltage of the last valve is as shown at c, Fig. 2. The back e.m.f. due to the inductance of the coils 22 is of the form b, so that the current in the coils is of the required shape a.

Filed: 1970-05-29
Abstract: 1298707 Injection needle SIEMENS AG 29 May 1970 [31 May 1969] 26072/70 Heading A5R [Also in Division H4] An apparatus for the location and injection of a fluid carrying passage in the human body comprises a locating vibrator 6 for ultrasonic emitting and receiving attached to a support 4, both of which are inserted into the hollow interior of a needle 1, such that the vibrator 6 is disposed immediately adjacent the needle tip. A high frequency transmitter is connected to the vibrator, which after having been placed flush with the skin at the conjectured position of the fluid carrying passage, emits and receives an ultrasonic beam. The exact position of the fluid carrying passage is determined when the frequency difference between the emitted and received signals reaches a maximum due to the Doppler Effect at the moving fluid in the passage. A measurement device connected to the vibrator by leads 9, 10 indicates the position of the bleed vessel and transmits it to a loudspeaker. The locating vibrator, Fig. 2, not shown (16) and its support (14) may alternately be positioned outside the needle where it transmits its beam to the fluid carrying vessel through an ultrasonic coupling conductor (15). The needle may then be guided through the bore hole in the vibrator and support to the fluid passage, the vibrator being attached to a transmitter, a measurement device and loudspeaker as before by leads (24, 25).

Abstract: 1375599 Anti-skid brake modulators GIRLING Ltd 21 May 1973 [6 June 1972 6 July 1972] 26229/72 and 31609/72 Heading F2F An anti-skid brake modulator comprises at least one first piston controlling hydraulic fluid flow from a pressure source to a slave cylin- ,der and operated through an abutment by a second piston which is subjected to fluid pressure on one area urging the first piston into a position to allow fluid flow to the slave cylinder and a chamber between the inlet and outlet having a minimum effective volume whereby when a skid signal occurs, pressure fluid acts on an opposed second area of the second piston to cause the first piston to cut off flow and increase the chamber volume, the pistons being side-by-side whereby the second piston second area extends from the abutment in the same direction as the first piston. Two such first pistons 43 whose axes lie in the same plane as the second piston 12 or 45 control respective two stage poppet or ball valves 53 for the brake fluid flow in a dual circuit, or the outlet from one chamber controlled by one such valve is connected to the input of a chamber for the other first piston in a single brake circuit. The second piston 12 or 45 is held in a leftward position by fluid acting on the first area and, via a radial flange 13 or 48 acts on the first pistons 43 to retain their valves open. However, a solenoid valve 32, 33, 35, 36 is actuated by an anti-skid signal to open communication between a high pressure inlet 27 from a pump and a passage leading to the extreme lefthand end of the second piston (the second area) which is greater than the first area thus moving the piston rightwardly, retracting the first pistons and closing brake circuit communication. The solenoid valve has two seats 30, 31 separated by a ball cage and guide integral with the seat 30. An outlet 37 to a reservoir normally communicates with the second piston second area. The second piston 12 or 45 alternatively has a righthand end sliding in a movable member 5 biased by springs 2, 3 or has a bore containing a further piston 54 acted on by a spring 56 or springs, both to provide an accumulator. An internal or external passage exists to provide the continuous high pressure communication with the second piston first area, or a flexible pipe communicates with a passage through the further piston. A switch 40 detects the extreme lefthand position of the flange 13 or 48, and a switch 39 detects the extreme righthand position (maximum pressurization) of the accumulator.
