Filed: 1972-01-28
Abstract: 1375211 Supply circuits for electron guns GENERAL ELECTRIC CO Ltd 28 Jan 1972 [29 Jan 1971] 3481/71 Heading H2H A glow discharge electron gun 1 is supplied by a circuit comprising a capacitance C in series with an inductance L2, so that in the event of an arc discharge occurring in the gun, the capacitor discharges to momentarily reverse the voltage applied to the gun thereby extinguishing the arc discharge. In normal operation, a D.C. supply circuit 6 causes a glow discharge between the cathode 3 and anode 4 of the gun, ions from the discharge bombarding the cathode which emits an electron beam 12 for heating a target 8 in an argon filled enclosure 2. When an arc discharge occurs between the cathode and anode the capacitor C, the capacitance of which is much greater than the self capacitance of the gun, discharges and undergoes damped resonance with the inductor L2 so that the anode 4 becomes negative with respect to the cathode thereby extinguishing the arc. The cathode is therefore protected against excessive arc current.

Abstract: 775,462. Pulse radar. MORLE, C. W. (Philco Corporation). Feb. 15, 1951, No. 3713/51. Classes 40(5) and 40(7) A receiver for radar or other pulses comprises an instantaneous AGC circuit including a detector 4 and delay line 7-9 and one or more diodes 24, 25 wholly or in part shunting the delay line so that the system is slow in applying increased control bias to a variable gain LF. amplifier 1 to decrease the gain but rapid in applying increased gain to the amplifier, i.e. positive and negative going voltages across the detector load resistor 6 experience different delays in being applied to the AGC line. Stepwise hunting of the AGC bias and output about a mean value following the initial portion of the received pulse (with a half period approximately equal to the delay of the network) is thereby largely avoided and the system returns more quickly to normal gain after termination of the pulse. The diodes 24, 25 may be replaced by a controllably conducting device operated by a difference in potential between two points of the delay line. A coaxial line can replace the delay line. Reference has been directed by the Comptroller to Specification 604,499.

Abstract: 768,870. Presses for separating liquids from solids. AMERICAN DEFIBRATOR, Inc. Feb. 8, 1955 [March 1, 1954], No. 3732/55. Class 46. Shafts 13, 26, each carrying a pressure disc (14, 25 respectively), are each inclined at a small angle to the horizontal, shown in Fig. 1, and at a small angle to the axis of the housing 33 for the discs, shown in Fig. 2. Each shaft is stepped and rotates in roller bearings 7, 10 and against a thrust bearing 11 within a sleeve 6 located in a bearing housing 5. Shaft 13 is driven by a motor 22, sprocket 20, chain 19, Figs. 2 and 5, and sprocket 18, Fig. 1; shaft 26 is not driven. Pulp or the like to be treated is delivered from a trough 57, Fig. 5, into a hopper 56 in which is driven a feed screw 58, the hopper communicating with an inlet passage 43, Fig. 2. The material passes round five-sixths of the region between the discs 14, 25, the residue being discharged at 45, Figs. 2 and 5, and the remaining one-sixth of the inter-disc region being closed by two radial walls 41, Fig. 1, and another (not shown). Access by the material to the inner ends of the shafts is prevented by a collar 46, Fig. 1, supported by the radial walls and a plate 40. Liquid discharged through screens 30 and perforated plates 28 on the discs, and falling from drip flanges 36 on the shafts, passes through perforations 38 in the housing 33 to a pipe 39. The bearing sleeve 6 for shaft 13 is secured in housing 5 but that for shaft 26 (and hence the shaft itself) is permitted limited axial movement. On excessive pressure building up between the pressure discs the right-hand sleeve 6 is forced outwards and rotates slightly a lever 64, Fig. 4, about a pivot 67 against the pressure of an adjustable spring 80, one end of which is accommodated in a fixed tubular part 81. A switch finger 83 on the lever 64 thereupon rocks a pivoted arm 86 to open a switch 87 controlling the circuit of the motor 61, Fig. 5, driving the feed screw 58. The switch 87 may also be arranged so that a greater movement of the switch finger causes the disc-driving motor 22 to be switched off. Alternatively the spacing between the discs may be controlled by the lever and adjustable-spring mechanism shown on the end of the sleeve 6 at the right-hand side of Fig. 2.
