Title: Improvements in or relating to cathode ray storage tubes
IPC: G01S7/28
Filed: 1947-09-29
Abstract: 658,961. Cathode-ray tubes. RADIO COR- .PORATION OF AMERICA. Sept. 29, 1947, No. 26288. Convention date, Sept. 27, 1946. [Class 39 (i)] The target electrode of a cathode-ray storage tube comprises a conducting element, a first layer of insulating material and a second layer of insulation material joining the first layer to the conducting layer, electrons with a sufficient velocity impinging on and passing through the first layer to produce a trapped charge image which can be sensed by electrons impinging on said target with less than the said sufficient velocity. The target comprises a metal plate 1 having thereon a peaked layer 21 of high dielectric material of several times the thickness which stops electrons of less than 5000 volts e.g. a barium and strontium titanate mixture applied by settling from a suspension. A thin film of collodion is applied by immersing in water and applying a drop or so of collodion which spreads over the tops 5 of the titanate crystals. A silicon dioxide film 4 is formed by evaporation, and on subsequent heating the silicon dioxide layer settles on to the crystal peaks 5 and the collodion is evaporated. The target T is mounted in a tube 7 with two electron guns 8, 9 with corresponding electromagnetic or electrostatic scanning units 10, 11. Gun 8 produces an electron beam B1 having velocities greater than 5000 v., and gun 9 a beam B2 with velocities below 5000 v. The unit 10 of the put-on beam B1 scans radially from saw-tooth generators G1, rotation of the deflection yoke changing the radial direction and the unit 11 is connected to saw-tooth generators G2. Signals are applied to the put-on beam B1 in which the electrons are fast enough to penetrate the silica layer 4 and build up a charge image on the back of the silicate layer by secondary emission from the titanate layer 2, the secondary electrons being too weak to pass through silica layer. The take-off beam B2 liberates secondary electrons from the silica layer (which it does not penetrate) and requires a large number of scansions to remove the charge laid down by B1. Signals taken from the collector anode 12 or from the signal plate 1 are fed to a kinescope and built up to a bright image. The target may be photosensitive so that a map or printed information may be projected thereon, e.g..in a radar system.

Filed: 1939-09-21
Abstract: 532,835. Turning-gear. BOSCH GES., R. Sept. 21, 1939, No. 26301. Convention date, Sept. 21, 1938. [Class 7 (v)] In an engine starter in which a starter pinion 16 on a sleeve 12 is connected to the shaft 11 of the starting motor by a friction clutch 18 tightened by a pressure member 17 threaded on the sleeve, which is displaced axially to engage the pinion with an engine member 41, the member 17 is rigidly held on the sleeve 12 by a locking member 31 until the pinion meshes with the member 41. As shown in Fig. 1, the pinion 16 is integral with the sleeve 12, which is moved axially by an electromagnet 44 acting through a rod 40, which has a collar 43 normally abutting against balls 33 in the end of the sleeve. The locking member 31 consists of balls, pins or the like normally held by an enlargement 42 of the rod 40 in engagement with recesses in the member 17. When the pinion is fully in mesh with the engine member 41, the enlargement 42 has moved past the balls 31, so that the member 17 is free to tighten the clutch under the action of the thread 14. The balls 33 in this position enter a groove 35 in the shaft 11 and a stop 47 on the rod 40 engages the end of the sleeve 12. In a modification, Fig. 3, the pinion 56 is integral with the outer member 57 of the friction clutch, the pressure member 55 of which is threaded on a sleeve 52 having an internal threaded connection with the starting-motor shaft 50. The locking ball 59 is normally held by the thread 51 of the shaft 50 in engagement with recesses in the member 55. Axial movement of the sleeve 52 and pinion 56 is effected by an electromagnet 66 through a lever 67 and a two-piece collar 65 slidable on the sleeve 52. The movement of the collar is transmitted to the sleeve through springs 70, 71. When the pinion 56 comes into mesh with the engine member, the ball 59 rides off the thread 51 and the pressure member 55 can tighten the clutch.

Title: Improvements in or relating to the separation of granular material such as coal and ores
IPC: B03B5/24
Filed: 1955-09-14
Abstract: 815,228. Washing granular materials. HARVENGT, E. Sept. 4, 1955 [Sept. 15, 1954; June 7, 1955], No. 26356/55. Class 82(2) Apparatus for separating granular material such as coal and ores from a grading by density has a plurality of means for separating fractions from the grading, and a pocketed wheel discharge device (2) provided with at least two discharge passages (18, 19) leading to the wheel, each passage being connected with one or more of the separating means, whilst the passages terminate adjacent t h e pocket wheel at different spaced locations. These locations may be spaced circumferentially or longitudinally of the wheel, or both. The grading may be by washing troughs, jigs or upward currents. Fig. 1 shows a washing trough 1 with independently controllable separating means grate 4 and adjustable opening 10, through which respectively fine and coarse particles of the lowermost layer in the trough (eg. shale) may pass into passages 18, 19 for discharge into the pockets 14 of the rotated drum 13, the material from 18 partially filling a pocket which is subsequently filled from passage 19. The device works at "full level"; and supporting currents of liquid led in at 5, 11 prevent undesired lesser density particles from passing through the separating means. The actual final discharge occurs at 17. The pockets may have recesses 22, Fig. 2, while the end 20 of partition 21 has a circumferential width in contact with the wheel 13 which is at least equal to that, 14<SP>1</SP>, of a pocket so as to prevent direct contact between adjacent pockets. Part 20 may also be separate, and adjustable radially of the wheel to allow for wear (Fig. 8, not shown). Fig. 10 shows a further arrangement as applied to a washing trough. In Fig. 4 a jig 23 is shown used in conjunction with a washing trough 1 having grating 26 and opening 25 along the trough corresponding respectively to openings 4, 10 of Fig. 1, the discharge products being led to passages 18, 19 terminating at the wheel 13 in longitudinally spaced but circumferentially aligned locations. Fig. 5 shows two jigs 23a, 23b in series, their screens 26a, 26b being in trough 1, and the discharges from 25 and 23b being combined and led to passage 19 while that from 23a passes along passages 18. A linkage 31 driven by the drive 32 of the pocket wheel (and also may of the jig) may be used to actuate obturating devices 27, 35, 37, 39 controlling the movement of products through opening 25, along conduit 33, and out of jig 23b respectively, so that the jigging action shall not be impaired. In the arrangement of Fig. 9 (not shown), products from the screens 26a, 26b of both jigs are combined in the passage 19, that from the outlet 25 being directed along passage 18

Abstract: 1431665 Two-part couplings TRW Inc 5 June 1973 26839/73 Heading H2E Portion 12 is secured to portion 14 of electrical connector 10, to effect connection between individual plug and socket connectors 28 and 50 respectively, by a bayonet type coupling ring 58 which provides further coupling pressure by means of deformed spring washer 68, after complete abutment of portions 12 and 14. At least one bayonet stud 56 is provided in shell 46 of portion 34, and engages in a sloping slot 60, so that on rotation of coupling ring 58, shell 46 abuts or bottoms against externally projecting flange 38 on shell 46 of portion 32. Electrical connection of plugs and sockets 28 and 50 is achieved. Further rotation of ring 58 results in its own movement in a direction towards portion 34, and engagement of preadjusted flange 64 against spring washer 68 which deforms. Flange 38 is provided with a slot 39, wherein is located an annular wave washer which tensions detent balls 44 (one only shown) in their slots 40 in the other leg of flange 38. A further longitudinally movable flange 72 is keyed by means of keys 74 in slots 76 in the internal circumference of coupling ring 58, and thereby rotates along with ring 58, until balls 44 engage part of their circumference in apertures 78 in flange 72. The dimensions of the spring washer 68 are chosen so that when ring 58 is rotated so that bayonet studs 56 move between positions A and B (Fig. 5) a comparatively large force is required to deflect spring washer 68, which suffers 75% of its maximum deflection at point B, then, between positions B and C relatively little torque need be applied to rotate ring 58, and at point C, balls 44 engage in holes 78, and spring washer 68 is fully deflected. It is stated that the large final spring washer deflection margin so introduced provides greater allowance for wear in the couplings and maintains a more reliable connection.

Abstract: 1,008,110. Controllable multivibrators. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. May 27, 1964 [July 9, 1963], No. 27047/63. Heading H3T. An astable multivibrator has the emitter/ collector path of a third transistor between one feedback capacitor and the collector of the corresponding multivibrator transistor so that if the third transistor is cut-off by an external signal the circuit becomes stable with both multivibrator transistors conducting. In the Figs. T1 and T2 form a conventional astable multivibrator which operates normally when transistor T3 is fully conducting. If T3 is switched-off by a signal at IC when T1 is conducting, the capator C1 will discharge through R5 and at some point T2 will start to conduct, although T1 remains conducting. If T3 is switched-off when T2 is conducting, T1 will ultimately conduct by normal multivibrator action. When T3 is switched on, the right-hand side of C1 becomes positive to earth and T2 is cut-off, the first cycle of the multivibrator operation then having the same form and period as later cycles and the first half-cycle always being of the same polarity. T3 can be an NPN transistor, in which case the emitter and collector connections are reversed.
