Title: Improvements relating to brake control apparatus for vehicles
IPC: B64C25/46
Filed: 1954-08-23
Abstract: 745,803. Fluid-pressure brakes. WESTING- HOUSE AIR BRAKE CO. Aug. 23, 1954 [Aug. 25, 1953], No. 24430/54. Class 103 (1). In an aircraft fluid-pressure brake anti-skid control system governed by an inertia-weight operated device 10 of the kind described in Specification 674,506, the fluid pressure acting in pipe 6 leading directly to the brake actuator 2 is made to operate upon a piston 35 linked to the pilot's control valve lever 17 in such a way as to assist the manual effort tending to open the valve. Then when, due to wheel slip, the control device 10 tends to release fluid pressure from the actuator 2 and consequently also from chamber 36 below piston 35, the fact that the wheel is tending to slip is made apparent to the pilot by the increased pressure on his foot necessary to maintain the control valve 7 open.

Title: Fluid distributor
IPC: B01D33/82
Filed: 1959-07-21
Abstract: 904,299. Rotary filters. PANMETALS & PROCESSES Inc. July 21, 1959 [Aug. 4, 1958], No. 24956/59. Class 46. [Also in Group XXIX] A seat 46, shown in Fig. 6 in cross-sectional plan and in Fig. 7 in sectional, developed form, for a rotary valve member 26 having a ported facing 42 of bearing material has ports 50, 52 communicating with pipes 82, 84 and an elongated or arcuate port 54 provided with adjustable partitions 60, 62, 64 whereby the period during which each of the ports 44 communicates with one of a series of pipes 86, 88, 90, 92 opening to the arcuate port can be adjusted. The valve may be used with an arrangement of sector-shaped moving-cell filter elements each of which is connected to one of the ports 44 and rotates with the member 26 about the axis of the latter on rollers as described in Specification 904,300. After the material to be filtered has been deposited on one of the cells the corresponding port 44 moves over the chamber connected to the pipe 86 which is subject to suction to draw off the liquid. As the valve member and filter cells continue to rotate successive wash liquids are supplied to the cells and are drawn off by suction applied to the pipes 88, 90, 92. Each cell is inverted as its port 44 reaches the port 50 to which air or steam under pressure is supplied to assist in removing the filter cake. The cell then resumes its normal position and is subject to suction through the port 52 to remove any remaining liquid and to restore the filter cloth to its flat condition. Each of the partitions 60, 62, 64 is pivoted at 68 on a spindle permitting adjustment from the outside and consists of a rigid plate enveloped in rubber &c., to permit deformation at the side edges where it engages the side walls of the port 54 and at the upper and lower edges to permit it to be adjusted while remaining in contact with facing 42 and with the base of the port 54. Alternatively the upper edge may be rigid and spaced from the facing 42. Also the portions of the side walls of the port 54 with which the partitions 60, 62, 64 coact may be straight instead of curved to facilitate sealing of the partitions. The invention is also applicable to valves in which the relative motion between the parts 26, 46 is rectilinear instead of rotary.

Patent GB-448212-A (GB)
Title: Product simulating leather and process for its manufacture
IPC: B29C37/00
Filed: 1935-09-09
Abstract: A product simulating leather is produced by treating coagulated and vulcanized latex with a solution of a sulphur chloride in a solvent which does not react upon the sulphur chloride, e.g. a solution of sulphur monochloride in benzol, and then with water before the sulphur chloride has been able to evaporate or to be fixed upon the rubber by decomposition.  The coagulated and vulcanized latex may be pure or associated with fillers or textiles, the vulcanization may have taken place before or after coagulation.  It is stated that the water decomposes the sulphur chloride forming, in the presence of the rubber, sulphur, chlorine and hydrochloric acid and these substances in the nascent state probably polymerize the vulcanized latex so that it loses all its thermoplastic properties.

Title: Improvements in and relating to the frequency modulation of radio signals
IPC: H03C3/14
Filed: 1946-08-22
Abstract: 615,073. Frequency mediation. BRITISH BROADCASTING CORPORATION, and HAMMANS, R.H. Aug. 22, 1946, No. 25138. [Class 40 (v)] In a V.H.F. transmitter, frequency modulation is effected by modulating the capacitance between the anode and screen, by potential variations applied to the suppressor grid of a pentode valve to vary the mutual conductance in the path between the suppressor grid and anode and thus, by the Miller effect, modulate the capacitance between the control grid and cathode, the screen grid being imperfectly decoupled. Modulating voltage is applied from the terminals 14 to the suppressor grids of the push-pull pentodes 22, 23. The value of the screen decoupling condenser 28 is such that the screens are imperfectly decoupled to radio frequencies, but the decoupling is made sufficient to prevent instability. The oscillation generator comprises two push-pull triodes 16 and 17 and the oscillations are applied from a tuned circuit 18, 19 to the control grids of valves 28, 29. The control grids are biassed by connecting them to the GB-2 terminal, and the suppressor grids are maintained at a potential slightly below that of the cathodes by connecting them to the GB-1 terminal. The modulated oscillations are developed across tuned circuit 24.
