Abstract: 728,448. Television pick-up tubes. PYE, Ltd. May 14, 1953 [March 7, 1952], No. 6005/52. Class 39(1). In a television pick-up tube in which during the frame fly-back period the storage target is subjected to electron irradiation to produce secondary emission, and simultaneously the collector electrode of the tube is pulsed negative to cause the emitted electrons to return to the target, the redistribution is effected in an even manner by rendering the field substantially uniform, e.g. by dividing the collector into sections at different potentials or by shaping the collecting surface. In the image iconoscope of Fig. 1 with photo-cathode 2, target 3, load resistance 7 and scanning gun 10, the photo cathode is pulsed during frame fly-back with diffuse light and the collector electrode is simultaneously pulsed negative to cause the emitted secondary electrons to return to the target. The collector electrode is divided into two discrete sections 17, 21 supplied from pulse generator 22 through variable resistors 23, 24, the amplitudes of the pulses being adjusted to give even redistribution of the returned electrons. More than two sections may be used, and one or more may be given a slightly positive pulse two secure the desired control. In an alternative (Fig. 2, not shown) the collector electrode is of annular shape with a flared surface facing towards the target. The electrode may also have the shape of a section of a cone. The various modifications may be combined.

Abstract: 1425784 Hydraulic boosters BENDIX CORP 12 Feb 1974 [16 Feb 1973] 06296/74 Addition to 1338889 Heading F2F In a hydraulic booster having a push rod 76 operating a piston 26 via a valve 32, controlling fluid pressure acting on the piston, or directly on the piston if the pressure thereon fails, a passage 98 in the push rod communicates a cavity between the piston and the rod with fluid pressure acting on the piston and is controlled by a valve 102, 106 spring biased to close the communication and opened by a linkage 108 responsive to relative movement between the rod and a part of apparatus connecting the rod to the valve. Movement of the rod 76 during normal actuation moves a lever 82 via a spring biased member 90 to move the valve 32 to throttle flow between a steering pump 20 and steering gear 22 and to supply a chamber 24 with the pressure fluid causing piston movement which carries a pivot 80 of the lever 82 to move to lap the valve 32. During such actuation, the valve 102, 106 remains open by reason of the linkage 108 being held as shown by a shoulder 92 of the element 90. If pressure fails in the chamber 24, the rod 76 moves the valve 32 against a stop 72 causing a sleeve 64 to block any subsequent inflow of fluid to the chamber 24 and then causes the shoulder 92 to move away from the end of the rod 76 allowing the valve 102, 106 to close in order to retain fluid in the cavity, thus avoiding travel of the rod which does not produce any actuation of the piston 26.
