Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/54
Filed: 1919-09-15
Abstract: 154,734. Cloud, J. W. Sept. 15, 1919. Fluid-pressure.-In a graduated release valve, the train-pipe and brake-cylinder pressures are balanced against an adjustable spring through the intermediary of a lever fulcrumed at one end to a fixed point. The train-pipe pressure acts through the passage 5 on a piston 3, and the brake-cylinder exhaust from the triple valve through a passage 11 on the valve 9. The piston 3 and valve 9 bear upon a lever 7 fulcrumed at 8, against the opposite side of which bears an adjustable spring device 17. Upon an increase in train-pipe pressure for a graduated release of the brakes, the valve 9 is moved towards the right to allow the brake cylinder exhaust to escape through the port 16 until the brake cylinder pressure has been reduced to such an extent that the spring device 17 can re-close the valve 9. A portion of the resistance to the movement of the valve 9 is normally furnished by the stiffness of the diaphragm 4. Should the diaphragm crack, a larger area of the piston 3 is subjected to trainpipe pressure, and the piston is moved on to its seat so that escape of air from the train-pipe is avoided.

Abstract: <PICT:0709752/III/1> Spherical bodies of uniform diameter for adsorption-towers, washing-towers, catalytic reaction vessels &c. are made from inorganic materials or active carbon mixed with water and clay, gypsum &c. to obtain a pasty mass which is formed into ropes and then fed through a pair of grooved rollers driven to revolve in the same direction.  The material may be extruded by a press b on to a conveyer c where it is cut into lengths by a cutter e.  Each length is pushed in turn off the conveyer and falls between the rollers d (one only shown).  When the rollers have the same diameter, the one which passes downwardly at the moulding point is given the greater velocity or, alternatively, two rollers of different diameters rotating with the same angular velocity are used.  The rollers do not quite touch.  The velocity of one of the rollers may be adjustable. The grooves may be of semi-circular, V-shaped or trapezoidal cross-section.  They may be made of aluminium and heated by induction.  Examples of materials moulded are active carbon, oxides, carbonates and other metallic salts, clay, gels of silicon and aluminium with, perhaps, the addition of sawdust, peat, pumice stone &c. to promote porosity or cement gypsum &c. to promote solidity.

Abstract: 892,050. Mercury switches. SPERRY GYROSCOPE CO. Ltd. May 2, 1958 [July 19, 1957], No. 23016/57. Class 38 (5). [Also in Groups XX and XXXV]  In an automatic erection system for a gyro vertical in which primary contacts of a mercury switch detecting tilt of the gyro control an electrical supply to an erecting torque motor, secondary contacts of the switch, associated with a higher voltage supply to the motor for rapid erection, are arranged so that the higher voltage supply is never interrupted by the primary contacts. In Fig. 2, a mercury switch 1 is mounted on the rotor case of a gyro vertical (not shown) so that tilt in one direction or the other completes a circuit between a central electrode 5 and one of electrodes 6, 7 thereby energizing, from a step-down mains transformer 10, the appropriate winding 2 or 3 of a twophase torque motor to erect the gyro by precession. Large angles of tilt cause the mercury switch to complete a circuit between electrode 6 or 7 and a corresponding auxiliary electrode 15 or 16 so that, if a push-button 18 is operated, full mains voltage is applied to the torque motor to effect rapid erection. The relative positioning of the mercury switch electrodes is such that as tilt is removed, interruption of the heavier rapid erection current takes place between the mercury and one of the auxiliary contacts. As shown in plan view, Fig. 3b, the lower electrodes 6, 7 are double to avoid loss of contact on movement about an axis perpendicular to the tilt axis. In a modified form of mercury switch, Fig. 4, a plurality of low voltage contacts is provided between which resistances are connected so that the motor current is increased progressively with tilt. Specifications 718,124 and 798,336 are referred to. Reference has been directed by the Comptroller to Specification 798,336.
