Title: Improvements in or relating to cathode ray tubes and arrangements therefor
Inventor: MOSS HILARY
IPC: H01J29/28
Filed: 1951-09-25
Abstract: 712,254. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Sept. 17, 1952 [Sept 25, 1951], No. 22357/51. Class 39(1) A cathode-ray tube comprising an electron gun including a cathode and one or more accelerating electrodes for generating a primary beam of electrons directed towards a fluorescent screen, is provided with a secondary-electron-emitting electrode arranged in the path of the beam so' that electrons from the beam will impinge on it and generate secondary electrons which travel to the screen with a velocity less than the velocity of the beam so that in operation any liability for negative charging of the screen by the impact of the primary beam is counteracted. In one embodiment, Fig. 1, the anode 4 has a frusto-conical end 9 which may be of nickel coated with barium and magnesium oxides so that it is secondary-emissive; the edges of the beam strike the end 9 and produce secondary electrons. The anode 4 may be connected by a spring contact 12 to a wall coating 10 joined by a resistive coating 11 to a further wall coating 6 connected to the main H.T. supply. Thus the primary beam may be accelerated to 1.5 kV energy but the secondary electrons will have an energy of only about 1000 volts since the anode 4 is about 1000 volts below the potential of the coating 6 due to the resistive coating 11; the negative charge produced on the fluorescent screen by the primary beam may thus be neutralized by the secondary electrons. In another embodiment, Fig. 2, (not shown, the anode 4 is tubular and is provided with a secondary-emissive grid across the end remote from the cathode to generate the secondary electrons. The anode is provided with a separate leadin terminal instead of being connected to a wall coating. As an alternative to these two arrangements a secondary emissive surface may be mounted directly from the final accelerating-electrode of the tube by means of a support or supports of high resistance material.

Filed: 1932-08-11
Abstract: 396,229. Fluid-pressure brakes. ALGRAIN, P., 120, Rue Parmentier, La Croyere, Belgium. Aug. 11, 1932, No. 22550. [Class 103 (i).] Automatic compressed-air brakes for railway vehicles provided with the usual auxiliary reservoir 6 and triple valve 8 are also provided with an additional augmenting reservoir 80 and valve device which reservoir, when the train-pipe pressure is raised above a predetermined amount sufficient to release the brakes, is suddenly put into communication with the train-pipe by means of the air released from the brake cylinder in order to supply the train-pipe 7 to ensure a prompt release. The valve device is divided into three chambers 87, 89, 91 by diaphragms 88, 90, a valve 85 being secured to the diaphragm 88 and normally closing a passage from the chamber 87 to the train-pipe. The brakes are shown released, the brake cylinder 2 communicating through pipe 3, triple valve 8, pipe 8k, chamber 89, and orifice 93 with the atmosphere, while the brake pipe communicates with the auxiliary reservoir 6 through groove 8g in the triplevalve piston 8a and with the additional reservoir 80 through check-valve 82 and throttle 83. When the train-pipe pressure is reduced to apply the brakes the triple valve moves to the right closing the groove 8g and connecting the reservoir 6 with the brake cylinder 2. The pressure in the reservoir 80 is retained by the valves 82, 85. When the train-pipe pressure is subsequently raised to release the brakes the triple valve moves to the left and the brake cylinder 2 is exhausted to atmosphere through pipes 3, 8k, chamber 89, and orifice 93, its differential action on the diaphragms 88, 90 forcing the valve 85 down against the action of the spring 96 so that air from the reservoir 80 passes to the train-pipe through pipe 92, chamber 87 and valve 85. The brake cylinder air also passes through a restricted, opening 94 to the chamber 91 and gradually equalizes the pressure above and below the diaphragm 90 which it finally moves upwards to close the valve 85. A cock 97 is provided to isolate each reservoir 80 and its valve device from the trainpipe.

Title: Improvements in or relating to coincidence detector circuit arrangements

Filed: 1958-07-17
Abstract: 858,199. Diode gating circuits. MARCONI'S WIRELESS & TELEGRAPH CO. Ltd. April 9, 1959 [July 17, 1958], No. 23027/58. Class 40(6). Fig. 2 shows a coincidence detector for producing an output on lead 10 only when positive going input signals are present simultaneously at leads 1, 2 and for preventing a noise signal being produced at the output simulating a useful signal even when the two inputs are not simultaneously present. The input signals at 1, 2 are applied to an AND gate comprising semiconductor diodes 4, 5 and also to an OR gate comprising diodes 11, 12 to produce signals at points 3, 13 which are applied to a differential circuit 14 which produces an output to operate relay device 15 when there is a difference in amplitude between the input signals. Since the AND circuit produces an output which is approximately equal to the smaller of its two input signals if large useful signals are present simultaneously at inputs 1, 2 the signals at 3, 13 are of equal amplitude so that no output signal is produced from differential circuit 14 and relay 15 does not operate. If a large signal is present at only one of the inputs 1, 2 the signal at 13 will be very much greater than the signal at 3 so that the differential circuit 14 will actuate relay contact 15 to insert attenuation in the output signal path 10. The delay device 18 and the pulse widening circuit 19 compensate for delay in circuit 14 and thus prevent any noise signal getting to the output 10 even for a short period of time. In the modification shown in Fig. 3 the differential circuit 14 is constituted by a long-tailed pair comprising triodes 14a, 14b the output from which controls electronic switch comprises semi-conductor diodes 15a, 15b which are normally biased by resistor 22 and diode 23. The switch is in the input lead to cathode follower 8 from which the output lead 10 is fed. Resistors 20, 21 attenuate signals supplied via 13 to the valve 14a to ensure that with signal and noise simultaneously at terminals 1, 2 the noise levels at the grids of tubes 14a, 14b are substantially the same and the signal at the grid of valve tube 14b is little more than at the grid of 14a attentuation is thus not inserted in the path of output lead 10. If there is no signal at one of the input terminals I or 2 the output from the long-tailed pair 14a, 14b causes attenuation to be inserted.
