Title: A distributor construction for compressed air brake systems for railway vehicles
IPC: B60T15/30
Filed: 1952-11-28
Abstract: 719,525. Compressed air-brake. KOVOLIS, NARODNI PODNIK, and DANEK, J. Nov. 28, 1952 [Dec. 3, 1951], No. 30221/52. Class 103(1) In a distributer valve for compressed air brakes for railway vehicles of the type in which the reduction in pressure in the brake pipe 10 is accelerated by passing some of the air from the pipe directly into the brake cylinder, this initial reduction is limited to a definite value e.g. 0.5 Atmospheres. When the driver first reduces the pressure in the pipe 10, the fall of pressure consequent in chamber 12 above the main diaphragm 15 enables pressure from the control reservoir 38 acting in chamber 16 to flex the diaphragm so as to move valve stem 17 and piston member 35 to open valves 28 and 29. The pressure in chambers 26 and 27 although sufficient to maintain valve 42 closed by spring 41 is however reduced by flow of fluid pressure into the brake cylinder 34 to a degree that causes valve 25 to open and allow fluid from the brake pipe 10 to flow directly to the brake cylinder by passages 18 and 24. After the brake pipe pressure in chamber 22 has been reduced by about 0.5 Atmospheres, control reservoir pressure acting on diaphragm 21 causes a valve 20 to close on a seat k and prevent further direct flow between brake pipe and brake cylinder. This caused a further reduction in chamber 27 which causes valve 42 to open to allow fluid from the auxiliary reservoir 45 to flow to the brake cylinder 34 under control of the main diaphragm assembly in the usual manner.

Abstract: 1,141,315. Colour television. SONY CORP. 6 July, 1966, No. 30343/66. Heading H4F. In a system for receiving colour television signals in which every third horizontal synch. pulse is attenuated, the unattenuated horizontal synch. pulses are separated out by a first synch. separator and drive a colour switching circuit for controlling the colour output of a picture tube, and all the horizontal synch. pulses are separated out by a second synch. separator and drive deflection circuits for the picture tube. In the embodiment of Fig. 1, linesequential colour video signals are obtained by combining the gated outputs of three synchronously scanned cameras 14, 16, 18 (each sensitive to a different one of the colours red, green, blue in stage 42. Circuit 46 receives horizontal and vertical synch. pulses from generators 22, 24, every third horizontal synch. pulse as extracted by a divider 26, and provides a composite waveform (Fig. 2, D) having every third horizontal synch. pulse attenuated. This waveform is combined with the video signals in stage 44, giving a composite video signal (Fig. 2, E) which is transmitted over link 50 to a receiving portion 12 of the system. After amplification, the video signal is applied to grid 54 of a picture tube 56 having vertical phosphor strips in a red-green-red-blue sequence and a colour switching grid 60 embedded in the non- red phosphor and serving to direct the electron beam of the tube on to a selected colour phosphor when supplied with a selected voltage from circuit 66. All the synch. pulses are extracted by synch. separator 75 and drive vertical and horizontal beam deflection circuits 76. The unattenuated horizontal synch. pulses are extracted by synch. separator 64 and trigger rectangular wave generators 68, 70 whose outputs are combined to give a staircase waveform (Fig. 2, I) which is applied to colourswitching grid 60 to cause colour switching in synchronism with the gating of cameras 14, 16, 18. Circuit details of the synch. separator stages are given (Fig. 4, not shown).
