Title: Improvements in or relating to Vehicle Brake Systems
IPC: B60T8/74
Filed: 1967-03-06
Abstract: 1,184,812. Fluid-pressure brakes. TRW. Inc. 6 March, 1967 [24 March, 1966], No. 10495/67. Heading F2F. [Also in Division G1] In an anti-skid braking system for a motor vehicle, a vacuum-servo actuator 30 is adapted to operate a check valve 84 to control the flow of fluid to the brakes 21, 22 of the rear wheel of the vehicle whenever a sensor means 70 responds to a given excess of angular deceleration over linear deceleration to operate a pilot and servo valve 60 which controls the actuation of the vacuum-servo actuator 30, to cause the rear wheel brakes to be released. As shown in Figs. 1 and 2 the sensor means is in the form of a decelerometer 70 provided with a cylindrical inertia mass 71 adapted to slide longitudinally under the influence of linear deceleration and to rotate relatively to a shaft 72 driven from the propellor shaft 16 of the vehicle whenever locking of the rear wheels occurs. Movement of the inertia mass 71 to the right as shown in Fig. 2 moves a linkage 52 and 58 to open a pilot valve 81 in the pilot and servo valve 60 and allow atmospheric pressure to enter a chamber 55 on one side of a flexible diaphragm 65 to urge a diaphragm actuated atmospheric valve 53 to its open position and allow a large volume of air to enter from the port 86 into a chamber 56 and thence to a duct 59 to move the piston 37 of the vacuum-suspended servo actuator 30 (Fig. 3) to the right and close the check valve 84 while at the same time increasing the volume in the chamber 31 to release the brakes on the rear wheels of the vehicle whenever locking of the rear wheels of the vehicle occurs.

Abstract: 435,606. Rope grips. POHLIG AKT.- GES., J., Zollstock, Cologne, Germany. April 5, 1935, No. 10637. Convention date, Feb. 27. [Class 78 (ii)] In load-carriers for singlerope cableways in which the carriers are supported on the moving rope by two cylindrical rotatable spirallygrooved rollers arranged with their axes parallel to the rope, the rollers 6, 7 are mounted to be shiftable within small limits and their rotation is braked to prevent undue slip of the carrier along the rope 5. The load is suspended from a beam having lateral guide wheels at the ends, and the two rollers 6, 7 are mounted in a box 3. Each roller rotates about a shaft 12 having a cone 11 toward one end engageable with a conical enlargement in the roller bore.

Abstract: 271,618. Brotherton, F. April 26, 1926. Mercury cut-outs. - A thermally operated mercury cut-out for use as a time-lag relay in circuitbreaker trip circuits produces a sudden reduction of current on overload and comprises a heating element in the form of a wire r contained within an inner tube a and carrying a rod u at its lower end dipping into mercury t. The rod u is secured to an electrode s normally in contact with the mercury and is insulated over a portion of its length by an insulating sleeve w. When the pressure produced by the heating of the air or other gas within the tube a is sufficient to force the mercury up into the outer tube b and break contact with the electrode s the resistance rod u is introduced in the circuit producing a sudden decrease of current therein. In a modification the heating and resistance elements may be contained in one limb of a U-tube.

March 16, 1965 [March 19, 1964 (2); March 20, 1964], Nos. 11629/64, 11741/64 and 11958/64. Heading H2A. A duct for a MHD device is made by stacking together a number of metal tubes each shaped to form a closed loop with insulation between the tubes, where portions of the loops that are in contact with the working fluid can be used as electrodes. The loops extend obliquely to the duct axis to lie in equipotential planes and thereby provide a series of interconnected confronting electrode segments in the duct so that a higher voltage is generated between the extreme electrodes. The size of the loops may increase to provide a tapered duct and the shape of the tube itself may vary to be elliptical on one side and circular on the other so that variation in the angle of the equipotential planes can be accommodated. The stainless steel or copper tubes are water cooled and insulated by alumina or similar material. They are supported either on a metal frame or by embedding the tubes in a sealing layer of resin bonded glass fibre. The parts of the tubes acting as electrodes may be plated with an electron emissive material, or have such material provided as an insert in the tubes. Various tube sections are described together with details of their construction. In the MHD generator described the combustion chamber and exhaust passage are connected to the generator duct by water cooled metal parts which can be used as the output electrodes. Subsidiary electrodes may be connected between the electrodes along the duct.
