Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/04
Filed: 1920-02-16
Abstract: 151,234. Thomas, T. H. Sept. 12, 1919,. [Convention date]. Fluid-pressure.-The handle of the driver's valve cannot be removed unless a straight air application of the brakes has been made. The equipment shown comprises a straight air emergency valve 1, a reservoir 4, and straight air, emergency, and reservoir pipes 6, 5, 10. For a straight air application, air is supplied through the driver's valve 2, to the pipe 6, thence by the cavity 21 in the valve 1 to the brake cylinder 3. The handle 14 of the driver's valve 2 has a notch 16 which is normally engaged by a catch 15 under the influence of a spring 19 acting on a piston 18. The chamber of the piston 18 is connected by a passage 20 to a port in the seat of the valve member 13, which in the straight air application position connects the port to the chamber 12, and the reservoir pressure thus admitted beneath the piston effects the disengagement of the catch 15. The handle 14 may then be removed by turning it to the usual " handle-off " position. By reason of the inclined faces of the latch 15 and notch 16 the handle can be applied with the catch in the engaged position.

Title: Improvements in and relating to regulation arrangements
IPC: H02P25/26
Filed: 1965-02-04
Abstract: 1,039,693. Automatic speed control. MATERIAL ELECTRIQUE S.W. Feb. 4,1965 [Feb. 7, 1964], No. 4873/65. Heading G3R. [Also in Division H2] A bridge network, comprising diodes 6 and controlled rectifiers 7, is connected in the rotor circuit of an induction motor. When a speed-responsive voltage derived from tachometer T is less that a reference voltage, a bi-stable element B1 provides firing signals for the rectifiers 7 so that the rotor circuit is completed through resistor 5 and the motor accelerates. When the motor reaches the reference speed, the element B1 changes its state whereby the rectifiers 7 are rendered non-conductive, so tending to reduce the speed of the motor. This cycle of operations is repeated to maintain the speed substantially constant. A high driving torque for speeds near synchronism is afforded by the addition of bi-stable element B2 which fires rectifier 12 when a pre-set speed is reached to connect resistor 11 in parallel with resistor 5

[Also in Divisions Fl and G1] A float-actuated valve 23 in a tank 13 for use in priming a centrifugal pump (not shown), is gradually closed by the rising level of water drawn through a conduit 14 by the vacuum created by a sliding-vane vacuum-pump (not shown) connected to float chamber 19 through a flexible hose 33 and the valve 23. During closing of the valve 23, the float arm 21 is moved about pivot 25, but once the valve 23 is closed any further rise in the water level will cause the arm 21 to move about a pivot 26 against the action of a spring 30 until a valve 36 is opened to permit air to enter the chamber 19 and cause a lowering of the water level therein. The valve 23 comprises a leather or other appropriate disc or diaphragm stretched across a member 24, and co-operates with a perforated brass disc 31.

Abstract: 525.180. Phase-difference measurements. STANDARD TELEPHONES & CABLES, Ltd., SCAIFE, F. N., and EARP, C. W. Feb. 17, 1939, No. 5322. [Class 37] [Also in Group.XL] In a system for the determination of direction, distance, altitude, or courses by electromagnetic radiation, of the kind in which a visual indication is given by indicating the resultant of two or more electrical vector quantities, the indicating instrument comprises a plurality of fixed field coils R1, R2, and a.moving system consisting of a rod or shaft R of magnetic material on which are mounted a plurality of angularly displaced magnetic vanes V1, V2, the rod or shaft R being encircled by one or more fixed coils E and the vanes being rotatable in the magnetic field of the fixed coils. The field coils R1, R2 are wound on flat spools and the vanes move in narrow slots therein. The coils R1, R2 are arranged with their axes at right-angles to avoid magnetic coupling. The moving system is damped by an eddy current disc T and magnets M and carries a pointer P which moves over a scale D1 marked in degrees and a further adjustable outer verge ring scale D2. A plate L shields the coil assembly from the magnets M. Fig. 1 shows the application to the radio compass described in Specification 490,940, [Group XL]. An aerial system LA1 has optimum sensitivity for east-west signals and its pick-up is modulated in a modulator M1 by an oscillator M01. A second aerial system LA2 has optimum sensitivity for north-south signals and is connected to a modulator M2 in which the signals are modulated by a different wave form from an oscillator M02. The oscillators MO1, M02 are connected to the field coils R1, R2 of the indicator. The outputs from the modulators M1, M2 are combined in an amplifier A with the pick-up from a non- directional aerial VA and after detection in a detector D the resultant modulation envelope is applied to the coil E of the instrument. The coils R1, R2 are energized at different frequencies and the coil E is energized by a combination of the same frequencies in varying amplitude and phase. The moving system takes up a position depending on the relative amounts of the frequency components and on the phase difference between the fixed and moving systems, and thereby indicates the bearing of the transmitting station. The indicator may be employed in the compass described in Specification 452,102, [Group XL], using a mechanically rotated aerial. In a modification for determining distance or altitude the phase of a transmitted wave form is compared with the wave form re-radiated or reflected by the distant object or terrain, the indicating instrument being of the type described. Such instrument may also be used in a course finder of the double tone type. Specification 162,471, [Class 37], also is referred to.
