Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T13/64
Filed: 1924-06-27
Abstract: 218,314. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Dean, W. E.). June 28, 1923, [Convention date]. Fluid-pressure braking-apparatus of the kind comprising a piston separating two chambers, one of which is connected with the main valve chamber of the triple valve, and the other of which forms an auxiliary reservoir for supplying the brake cylinder in such a manner that a graduated release of the brakes can be obtained, is provided with a manually operated cock adapted to connect the two chambers so as to suppress the graduated release action when desired. The piston 15 separate a chamber 19 in permanent communication with the valve chamber 5 of the triple valve by passage 37 from a chamber 17 which, in the release position of the triple valve as shown, is connected to the brake pipe 3 by passage 31, port 32 in the main slide valve 7, cavity 33 in the graduating slide valve 8, port 34, and passage 18. In this position also the brake cylinder 12 is connected by passages 13, 27, 28, 29 to an exhaust port 30, and the valve chamber 5, piston chamber 19, and a reservoir 6 are connected to the piston chamber 17, and thus to the brake pipe by the passage 36. The piston 15 is connected to the brake rigging as well as the piston 10. If the brake pipe pressure is reduced to effect an application of the brakes, the triple valve piston 4 at first moves the slide valve 8 to cut off the chamber 17 from the brake pipe and to close the exhaust connection to the brake cylinder 12 and the main valve 7 is then moved to connect the chamber 17 to the brake cylinder through passages 18, 38, 39, 40, 13. The reduction of pressure in the chamber 17 causes the piston 15 to move downwardly, thereby reducing the pressure also in the chambers 19 and 5, and when this pressure falls below that in the brake pipe the slide valve 8 will be returned to cut off the chamber 17 from the brake cylinder. A graduated application of the brakes is thus obtained. To effect a graduated release of the brakes the brake pipe pressure is raised slightly above that in the chambers 5, 19, 6, so that the slide valves 7, 8 are returned to the release position in which the brake cylinder commences to exhaust, and the chamber 17 is supplied, causing upward movement of the piston 15, and an increase in the pressure in chambers 5, 19, 6 by the consequent reduction in volume, and when this pressure exceeds that in the brake pipe and piston chamber 2 the slide valve 8 is moved back to lap position to stop the exhaust of the brake cylinder. When it is desired to suppress the graduated release action a cock 21 is turned from the closed position shown to one in which a passage 24 therein connects passages 25, 26 leading from the piston chambers 17, 19, so that the chambers 17, 19, 6, 5 act as a single capacity.

Title: Improvements in & relating to electric arc devices
IPC: H01J17/54
Filed: 1922-06-02
Abstract: 203,382. Freedman, P. June 2, 1922. Discharge-gap apparatus.-In an arc discharge device for use as a rectifier, amplifier or oscillation generator, in which the discharge is controlled by a grid electrode, the three electrodes consist of a refractory material such as tungsten mounted on stalks of refractory conducting material, the anode 1, Fig. 1, being in the form of a sphere, plate, or block, the cathode 3, a filament, sphere, or block, and the grid, a ring, sphere, or block. The bulb contains a gas such as nitrogen, argon or neon at a pressure of from 0.5 inch to 28 inches of mercury. The grid is maintained at a positive potential. The curve ADE, Fig. 4, having a pronounced negative characteristic shows the relation between the anode voltage and current when the grid is in use, and curve ABC the relation when the grid is not used. The anode and cathode are so proportioned that when the device is operating as a rectifier the anode is at red heat and emits positive ions only, and when used as an amplifier the anode is at white heat and emits positive and negative ions. The arc may be started by means of a high voltage discharge between the anode and grid, or for large powers an auxiliary discharge may be produced between an auxiliary filament cathode and a main spherical cathode, the auxiliary discharge being interrupted when the main discharge has started.

Title: Improvements in or relating to meters for steam or gas
IPC: G01F1/50
Filed: 1929-05-17
Abstract: 333,625. Soc. Rateau. March 20, 1929, [Convention date]. Tell-tale apparatus.-An electric meter for measuring the flow of steam or gas is actuated by the variations in the intensity of a high frequency alternating current, the variations being produced by a variable impedance modified by the flowing fluid. The impedance, is placed in a circuit in which the current is rendered independent of variations in frequency in the sourcecircuit. Means may be provided to neutralize changes due to variations in the static pressure and temperature of the fluid so that the weight of fluid flowing per unit time may be directly measured. The impedance may be a condenser with one armature a fixed and the other b mounted by means of a pendular system d, d<1> and exposed to the flow of the fluid in a pipe c, Alternating current from a high-frequency source, e.g. a thermionic valve, is supplied to the meter circuit through the windings j, j<1> of the source and meter circuits respectively, a loose coupling being formed between j and j<1> in order that the frequency in the meter circuit may be independent of changes in that of the source circuit. Changes in static pressure of the fluid are neutral ized by a condenser mounted in parallel with the main condenser a, b, with armatures e, f, fixed and movable respectively, the latter being connected through a rod i, pressure gauge h, and tube g with the flowing fluid in the pipe c. Variations in temperature are neutralized either by a resistance m, Fig. 1, in series with the main condenser, or a thermometer n, Fig. 2, acting on a movable armature of a condenser in parallel with the main condenser. In the form illustrated, Fig. 2, the condenser has both armatures e, f, movable, the armatures e moving with variations in static pressure and the armature f with variations in temperature. In a modification, Fig. 3, the condenser a, b is mounted in a branch from the pipe c and actuated by the dynamic pressure which may be amplified by means of an orifice in a thin wall, a nozzle, or a Venturi tube. The pressures in front and rear of an orifice l in a thin wall in the pipe c are transmitted by tubes o, p to chambers q, r separated by a diaphragm s carrying the movable armature b of the condenser. The meter k may be graduated direct in kilograms per hour and the variations in the current may act on a recording or integrating apparatus. The term " high frequency '' is used to mean a frequency of the order of 100,000 cycles per second and over.
