Title: Improvements in or relating to centrifugal clutches
IPC: F16D43/18
Filed: 1958-06-02
Abstract: 832,894. Friction clutches. REGIE NATIONALE DES USINES RENAULT. June 2, 1958 [June 28, 1957], No. 17569/58. Class 80 (2). In a centrifugal friction clutch in which different friction linings become operative according to the relative rotations of the driving and driven shafts, clutch shoes 7, having main linings 8 and secondary linings 9 disposed respectively behind and in front (in relation to the normal rotation) of the pivot pins 6 for the shoes and the centrifugal weights 5, are also pivoted at 12 on rocking members 11 pivoted at 20 on the weight 5. Sockets 14 containing spring-loaded balls 15 engaging cam faces 17 on the driving flywheel 3 and a plate 18 secured to the pins 6 provide a braking system on the shoe movement. Strong springs 19 connect between the sockets 14, engaged in slots 21 in the weights 5, and the pins 6 to urge the shoes to their rearmost position in which linings 9 contact the driven drum 1. At rest the shoes are in the position A, Fig. 2, with the lining 9 in contact with the drum 1 for tow-starting of the vehicle. With the flywheel 3 at idling speed the members movable about the pins 6 are balanced and the clutch is completely disengaged as at B. Increase in speed causes weights 5 to urge linings 8 into engagement with the drum at which stage the rocker 11 tilts about pin 12. At a predetermined speed the weights 5 are prevented from further movement by shoulders on the flywheel 3 and plate 18 to limit the transmissible torque. At this speed the balls 15 pass in front of the cam faces and act to retain the transmissible torque to a speed below that associated with that torque, this prevents premature release of the clutch on vehicle deceleration near engine idling speed.

Abstract: 958,752. Fluid-pressure brakes. COMPAGNIE DES FREINS ET SIGNAUX WESTINGHOUSE. May 11, 1962 [May 16, 1961], No. 18159/62. Heading F2F. In an electro-pneumatic braking system comprising a main reservoir pipe CP and a brake pipe CG, the pressure in which is controlled by an electro-pneumatic braking valve 12, a pneumatic relay valve 2 is arranged to be operative by alteration of the pressure in the main pipe CP to cut off the braking valve from the brake pipe, whereby in the event of a failure of the electric supply the driver, by operating a valve to alter the pressure in the main pipe, can release the brakes and use pneumatic means for subsequently applying the brakes. The invention is applied to a fail-safe system in which current is cut off from the coil of the braking valve 12 to apply the brakes. The brakes are thus applied fully in the event of a current failure, since the closure member 8 of the relay valve 2 is normally maintained open by pressure in the main pipe CP acting on a piston 4. In this event, the driver opens a valve to exhaust the main pipe CP, so that spring 6 can close the member 8 and restore pressure in the brake pipe to release the brakes.

Filed: 1940-12-28
Abstract: 544,262. Valves. GRAVINER MANUFACTURING CO., Ltd, and MATHISEN, A. Dec. 28, 1940, No. 18178. [Class 135] [Also in Group XXI] A fire-extinguishing system comprises an extinguisher from which two or more conduits extend to a number of different points of discharge and a distributing valve having a normal position whereby the fluid is discharged to a selected point but which is capable of operation from a remote point to divert the fluid to a secondary point of discharge. The invention is described in connection with a twin-engine aircraft, a, Fig. 1, denoting the fuselage, and b the engine nacelles built out on the wings c. A fireextinguishing liquid container 3 is associated with each engine, and is connected by a conduit 12 to a valve device d of the kind described in Specification 524,921, [Group XXI], from one outlet 24 of which a perforated conduit 25 surrounds a fuel tank 26, and from another 21 a conduit 22 is associated with the engine. The various parts are operated electrically, the wiring arrangement being such that, on the closing of flame or temperature rise responsive switches 2 associated with the engine, fluid from the container 3 passes via the conduit 12 through the valve to the conduit 23 and the discharge piping associated with the engine. When, however, the pilot or other person operates a push button switch 28, the valve is operated to shut off the outlet to the conduit 22, and to open that to the conduit 25 and the discharge piping associated with the tank 26. Alternatively, or additionally, this change over may be effected by the closing of a flame or temperature operated switch 2a adjacent the fuel tank. Fig, 2 shows the valve d, the valve element 35 being mounted on a spindle 36 which is normally held in a position to close the outlet 24 leaving the outlet 21 open by the engagement of spring-pressed balls 50 in a grooved recess 49 in the right-hand end of the spindle. When, however, the push button 28 is operated, or the switch 2a is fused, an electro-magnet 33 is energized to operate an armature 44 on the spindle and to move the spindle backwards so that the valve element opens the outlet 24 and closes the outlet 21. The electrical equipment for effecting discharge of the containers 3 also includes an inertia element operated switch 1, a gravity element operated switch G, and a pilot or other personnel operated push button switch P, all operating in known manner. Specifications 458,429, 510,442, and 520,714, [all in Group XXI], also are referred to.

Filed: 1936-07-01
Abstract: <PICT:0477529/IV/1> <PICT:0477529/IV/2> <PICT:0477529/IV/3> <PICT:0477529/IV/4> In wet-spinning processes for the production of filaments, yarns, and the like, the spinning solution is extruded into a coagulating medium moving in the same direction as the filaments or the like, through a vessel provided with one or more sheets of gauze extending across the vessel substantially normal to the direction of flow of the medium.  By this means turbulent motion of the medium is reduced or eliminated.  According to another method, the spinning solution is extruded into a coagulating medium moving in the same direction as the filaments or the like, from a shaping device having streamlined contours.  The process is of particular advantage at high spinning speeds, e.g. 150 to 400 metres per minute or more.  Pulsation, due to the pump circulating the coagulating medium, may be reduced by having a vessel of large capacity in between the pump and the coagulating vessel. Preferably, it has a large cross-sectional area and is provided with sheets of fine mesh extending across it.  When artificial materials are stretched in the coagulating bath and their velocity increases along the length of the bath, the velocity of the coagulating medium may be increased at the same rate by decreasing the cross-section of the bath in the direction of travel of the materials.  A jet 11 streamlined as shown in Figs. 3 and 4, or in Fig. 5, is contained in a coagulating vessel 10 which is provided p  with gauzes 15 and 16.  A pump 24 circulates the coagulating medium through the coagulating vessel 10 and a tank 25 of large capacity, provided with a partition 28 and gauzes 29 and 30. Specifications 340,324 and 371,343 are referred to.
