Abstract: 730,860. Trough-shaped light reflectors. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 19, 1952 [Nov. 22, 1951], No. 27425/51. Classes 75 (2) and 75 (4). In an optical system consisting of two trough-shaped reflecting surfaces 2, 3 of substantially parabolic cross-section arranged back to back and having the portions lying between their lines of intersection removed so that a horizontal elongated light source 1 can be located at the coincident line foci of the reflecting surfaces, the outer portions 5 of a pair of flanks of the reflecting surfaces are so shaped as to direct the light incident upon them across the central planes 4 containing the common line focus and the axes of the unmodified parabolic reflecting surface at angles to the central planes which increase as the distance from the apex increases and are extended beyond the other pair of flanks so as to reflect light towards the area obscured from the source by the other pair of flanks. The flanks directing the light across the central planes are so shaped that light from their inner parabolic portions do not strike their outer portions 5. The reflectors are enclosed in a bowl which is figured to spread the light in vertical planes. Specification 621,716 is referred to.

Title: Valve mechanism for train stopping apparatus
IPC: B61L3/04
Filed: 1923-01-22
Abstract: 219,552. Webb, J. F. Jan. 22, 1923. Fluid - pressure.- An air brake valve mechanism for stopping trains independently of the driver comprises a normally open valve 36 for controlling the passage of air from the driver's valve, connected at 51, and a normally closed valve 17 controlling the passage of air from the train pipe to a signal whistle and atmosphere at 11, the two valves being so actuated when a cam 32 is rotated by track-actuated means that the valve 36 closes and the valve 17 is opened to vent the. train pipe and apply the brakes. The valve 17, which is provided with locating-ribs 23, seats on a part 16 carried by a partition cylinder 14 having ducts 22, one of which, when the parts are assembled, is caused to register with the outlet 11 by the co-operation of ribs 20 with a locating-lug 21, Fig. 3, carried by the main casing 1, and the valve is connected, through a spring 25, Fig. 6, a yoke 26 position by the co-operation of ribs 27 with the ribs 20, and a roller 29, with a slot 31 in the cam 32. Similarly the valve 36, which has guide ribs 40, is connected through a yoke 39 and a roller 41 with a slot 43, 44 in the cam, the yokes 26, 39 being adapted to straddle the cam to prevent their axial rotation, and the rollers 29, 41 being carried on pins which are retained in position by lugs provided on a cover plate. With the ports in the normal position shown in Fig. 4, air passes from the driver's valve, through the strainer 45, passage 46, chamber 2, and strainer 50 to the train pipe, and the valve 17 is held closed, but when the shaft of the cam 32 is actuated bv means controlled from the track, the entry of the roller 41 into the port 44 of its slot permits the valve 36 to close under the pressure of its spring 38, thus cutting off the driver's valve from the train pipe, and the inner face of the slot 31 acting on the roller 29 opens the valve 17 to vent the train pipe through an audible signal, and the brakes are applied. In a " proceed " action, the valves are returned to their normal position when the plunger on the train passes off the ramp, but in a " stop " action the valve 36 remains closed and the valve 17 is kept open. The slot 43, 44 is enlarged at 44 so that when the brakes are applied from the track, the valve 36 may be free to rise against the spring 38 to allow the driver to make an emergency application through his valve. The valve chamber 2 is connected to the train stop plunger by the passages 55, 54, 53. Specification 219,345 is referred to.

Title: Internal combustion turbine
IPC: F02C3/34
Filed: 1935-10-08
Abstract: 460,794. Gas turbines. HONERT, A. VAN DEN. Oct. 8, 1935, No. 27769. Convention date, Oct. 9, 1934. [Class 110 (iii)] In an internal-combustion turbine, the relative positions of the nozzle and fuel jets are such that the amount of fuel burnt when the mixture reaches the nozzle throat is enough to raise the temperature of the mixture well above ignition temperature. In the divergent portion of the nozzle combustion continues, but any further increase in temperature is counteracted by a decrease due to the expansion of the gases. The jet from this nozzle can be used either alone to drive a gas turbine or it may be led to an injector where it induces a large mass of gas which passes with it through the.turbine. The inlet end of the jet apparatus g connects with the outlet end of the turbine t through a cooler k whilst the outlet end is connected to the turbine inlet. As combustion gases are continuously being added to the circuit an outlet for exhaust gas is provided where the pressure is atmospheric or above. In a modification, the jet apparatus can be used to create a flow of gas at atmospheric pressure or as a compresser of the gas which expands in the turbine blades.

Abstract: 636,117. Gyroscopic apparatus. HAYMAN, C. M. Sept. 18, 1946, No. 27993. Convention date, Nov. 21, 1944. [Class 97 (iii)] [Also in Groups XXX and XXXIII] A gyroscope is used to produce the turning moment for steering a ship or torpedo or for turning a gun, searchlight, or railway turntable. The gyro 22 is mounted in a gimbal 21 with its axis of spin across the ship. To produce the steering couple one of the solenoids 24, 25 is actuated to tilt the gimbal ring. The solenoids may be controlled by hand or by a control gyro 32 which, when the ship leaves a set course closes either of the contacts 44, 45. If the ship should be turned rapidly by external force damage to the steering device is prevented by the arm 59 reaching limiting contacts on the plate 56, actuating a solenoid to unlock the gyro from its support. In a modification, the gimbal ring is tilted. by the precession couple of a separate gyro which is rotated about a vertical axis by an electric motor under the control either of a hand steering control or of an automatic control gyro.

Filed: 1971-06-16
Abstract: 1338959 FET gating circuits RCA CORPORATION 16 June 1971 [18 Sept 1970] 28159/71 Heading H3T The capacitance 12a at the junction between a first F.E.T. N3 and a plurality of F.E.T.'s N4, N4C is held precharged to +V DD  by a switch such as F.E.T. P 3 , which turns off only when the F.E.T.'s N 3 , N 4 , N 4 C respond to certain inputs. One bi-stable memory cell 10a responds to inputs, or delivers outputs, on lines D 1 , D 0  when a select signal X 1  turns on N 4 , N 5  and Y 1  turns on N 3 , N 6 . Y 1  simultaneously turns off P 3 , P 4  which have been precharging capacitances 12a, 12b on lines 13, 15. The lines D 1 , D 0  are oppositely biased to write into a selected cell, and are held at +V DD  during reading, one or other being lowered in potential according to cell state. In another embodiment (Fig. 3, not shown) all P type MOST's are used and polarities of the signal and bias voltages accordingly adjusted. Here the precharging F.E.T.'s (P 16 , P 19 ) have their gates controlled by the D 1 , D 0  signals instead of the Y signals. This means they conduct during reading, but the effect is minimized by making their conductances low compared with the other F.E.T.'s.
