Title: Gain controllable image intensification system
IPC: H01J29/98
Filed: 1970-06-04
Abstract: 1364432 Cathode-ray tube circuits HUGHES AIRCRAFT CO 4 June 1970 [4 June 1969] 27121/70 Heading H4T An image intensification system comprises, Fig. 2, intensifier tubes 17, 19, 21 connected in tandem, tube 17 being a pentode and having magnification properties and having its gain varied by varying the potential applied to zoom electrode 50. The tubes 19, 21 are diodes and have their gain varied by varying the voltage applied to anodes 38, 39 by a potentiometer 61. The tubes 19, 21 are protected by a resistor 53 through which their combined photocurrents flow. However, since the tube 21 has a much larger photocurrent than the tube 19, the amplitude of the photocurrent of tube 21 effectively controls the amplitude of the voltage applied to the anodes 38, 39 determined by the volt drop across the resistor 53. Thus the light gain of the system is controlled to protect the tubes 19, 21 from damage. In order that the system may have the characteristic shown by curve 13 in Fig. 1 the tube 19 is arranged to cut off at a higher anode potential than the tube 21. Thus, tube 19 may cut off at voltages below 4 kV and tube 21 at voltages below 3 kV. The tubes 17, 19, 21 have their input and output optical elements 15, 27; 23, 29; 25, 31 formed by parallel-arranged optical glass fibres. In a modification (Fig. 3, not shown) a diode tube similar to diodes 19, 21 replaces the tube 17 and the anode of this third diode is also connected to the H.V. supply through the resistor 53 whereby the system serves to protect all three tubes. A different H.V. supply system for the tube anodes is described with reference to Fig. 4 (not shown).

Title: Improvements in or relating to variable displacement pumps
IPC: F02M41/08

Abstract: 722,864. Swash-plate pumps. BENDIX AVIATION CORPORATION. Oct. 30, 1952. [Nov. 1, 1951] No. 27325/52. Class 102 (1). In a swash-plate pump, the pistons 44 are loaded by springs 78 and carry slippers 74 engaging the swash-plate 61 that is carried by an adjustable ring 60 carried by trunnions. A ring 64 surrounds the slippers 74 and pivots on the spherical surface 62. The inclination of the swash-plate is increased by an adjustable spring 105 acting through link 112. The ports at the end of the cylinders 42 co-operate with inlet and outlet ports 94, 96 in a valve plate 86, which are connected to the inlet 10<SP>1</SP> and outlet 22 respectively. The ports 94, 96 are not symmetrical with the axis of the plate 86 which corresponds to the position of the cylinder ports in which the pistons are at top and bottom dead centre and are arranged that the opening to inlet or outlet is delaved so that the delivery pressure existing in the cylinder at top dead centre and before opening to inlet, acts against the spring 105 to reduce the inclination of the swash-plate. The effect of the inertia forces of the pistons and the loading forces of the springs 78 on this adjustment is described. The pump is shown as delivering fuel to a turbo-jet engine in which the outlet 22 is connected to a control valve 24 in turn connected to a control unit as described in Specification 688,546, [Group XXVI]. The control valve 24 has a slide valve 138 actuated by a spring-loaded diaphragm 144 to adjust the inlet pressure to the control unit to maintain constant the pressure difference between the inlet and outlet pressures of the control unit.

An electric switch comprises a fixed contact 17, a movable contact 18 biased towards the fixed contact but held out of engagement therewith by a restraining member 19 which is biased away from the fixed contact, an operating plunger 21, and an actuating member 28 which is biased away from the plunger 21 by a spring 31. When actuating member 28 is pushed inwardly against spring 31 it engages plunger 21 which in turn disengages restraining member 19 from movable contact 18 so that contacts 17 and 18 close. A member 32 limits inward movement of actuating member 28 and plunger 21 inwardly so that, in the position where the contacts 17 and 18 engage, the restraining means 19 is held out of engagement with both contacts. The housing of the switch is screwthreaded to facilitate mounting.

Abstract: 713,405. Frequency modulation. BENDIX AVIATION CORPORATION. Oct. 31, 1952 [Nov. 5, 1951], No. 27487/52. Class 40 (5) A thermionic reactance valve 34 has its anode connected to the tuned circuit 12 of a valve oscillator 25 through a resistor 18 with the object of increasing its frequency range and linearity. As shown, the tuned circuit comprises an inductance coil 12 having a three-point connection to the electrodes of a pentode oscillator valve 25. Quadrature voltage is applied to the grid of the pentode reactance valve 34 through a phasing network 30, 45, 31, 33 connected across the coil 12 ; and signal voltage applied to the grid at a terminal 43 varies the mutual conductance of the valve 34 and so varies the frequency of the oscillations generated. The Specification includes a diagram, Fig. 3 (not shown), indicating that a suitable value of the resistance 18 permits linearity of frequency control over a wide range of frequency. In a simpler form of circuit, Fig. 1 (not shown), the valves are of triode type, and the phasing network comprises a resistance-capacity potential divider. The Specification includes a mathematical analysis of the circuit, which indicates that a low but finite capacity should be present between anode and cathode of the valve 34.

The three carriers 9, Fig. 1, each comprise a sleeve 18, to which is secured at one end a helically slotted sleeve 25 ; within the sleeve 25 a longitudinally slotted sleeve 27 is rotatably secured by a collar 26. A sleeve 29, provided with projections 30 in the form of helical grooves of high pitch, is secured to the sleeve 27, and, when the carrier is advanced, engages grooves 8 on a cone 7 secured within the tip 5, so that rotation of the tip 5 advances the cosmetic stick 33, held in a sleeve 31, in the usual way. The rear end of the sleeve 18 is secured to a blade spring 11 which carries an elongated knob 12. The web 13 of the knob 12 is trapezoidal in section and slides in a slot 14 in the casing 1, and at the forward end of its travel is guided by an inclined forward edge of the slot into engagement with an offset notch which has an inclined rear edge to engage the edge of the web 13. The carrier 9 is pulled towards inactive position by a spring 23 surrounding a rod 21 in the inner end of the sleeve 18. The thickened end 24 of the rod 21 engages a notch 38 in a plate 37 and is retained by a hole 40 in a plate 39. At the end of the retracting movement of the cosmeticstick 33 continued rotation of the tip 5 turns the whole carrier 9 in a direction to release the web 13 from the notch of the slot 14, so that it may be retracted by the spring 23. The slot 14, is closed by the knob 12 in the inactive position and by the spring 11 in the active position. In the modification shown in Fig. 9, the retracting compression spring is mounted inside a separate sleeve 51, carried by a blade spring 44, to which is secured a longitudinally slotted sleeve 4. The helically slotted sleeve 48 rotates on the sleeve 42 and carries the projections 49<1> for engagement with the casing tip.

Abstract: <PICT:0463961/III/1> In the production of stabilized benzine by the destructive hydrogenation of carbonaceous materials at pressures of about 100 atmos., the products issuing from the reaction space are cooled under pressure to atmospheric temperature, the pressure is then released to an elevated pressure below 100 atmos. but above 3 atmos., the gas liberated being separated, and the liquid product is stabilized and separated from the higher boiling fractions. The crude mixture of middle oil, benzines, and gas issuing from a reaction vessel in which middle oil is destructively hydrogenated under 200--300 atmos. pressure is passed through a pipe 1 into a cold catchpot 2 in which the pressure is released to 20 atmos. p  The released gas free from gas benzine escapes through a line 3 while the benzine and middle oil are passed through a preheater 4 into a stabilizing column 5.  Propane and most of the butane are distilled off and escape through a pipe 6 while the middle oil is separated in a column 8 from the benzines which are condensed in a cooler 10 and collected in a receiver 11.  Benzines and mixtures of gaseous hydrocarbons obtained in other destructive hydrogenation, cracking &c. processes may be added to the gas-phase destructive hydrogenation of the initial materials so that these gases also are refined and stabilized.  The destructive hydrogenation is carried out in the presence of the usual catalysts, e.g. molybdenum, tungsten, tin, vanadium, rhenium, manganese, iron, cobalt, nickel or their oxides hydroxides, sulphides, &c.
