Abstract: 1486937 Mechanical switches J D KINNEAR 6 Dec 1974 [7 Dec 1973] 52788/74 Heading H1N [Also in Division H2] A manually operated switch for isolating the battery in a battery operated vehicle has an electromagnetically operated blocking means to prevent the switch from being closed in the event of a contactor in the motor control system (see Division H2) being welded closed. The electromagnet 128, Figs. 1, 9 is connected across the fixed contacts 16, of the switch as by wires 130, 132 and if current passes through a weldedclosed contactor the electro-magnet operates to pivot a lever 138 against the action of a return spring 136 so that its end 142 engages over a hole 144 beneath a plunger 72 attached to the moving contact cross bar 46 and prevents movement of the switch actuator 48, 50. A fixed pair of tubular contacts 16, Fig. 4 comprise tulip connectors 26 retained by ring springs 32 and aligned axially by flared ends 24 for engagement and disengagement by bridging tubular contacts 44 mounted on the conductive cross-bar 46. The tubular contacts 44 are slidably guided on insulating rods 38 extending between a housing wall 40 and the fixed contacts 16 and have ring ends (62) Fig. 6 (not shown) of material such as copper-tungsten or berylliumcopper to resist arcing. The switch actuator 48, 50 acts against a return spring 58 which urges a plunger 56 against a screw head 60 on the contact housing 14. The actuator 48, 50 is retained in the closed circuit positions by the arm 66 of a U-shaped spring latch 64 which engages in a goove 76 on the end of the plunger 72. The latch 64 is released by a push knob 82 attached to a slider 80 engageable with the latch 64 and urged outwardly by a spring 80. On release, the movable contacts 44 and crosshead 46 disengage from the fixed contacts 16 under the action of the spring 58.

Abstract: 1284748 Cine projectors BELL & HOWELL CO 30 Oct 1969 [19 Nov 1968] 53206/69 Heading G2E A cine projector has means for simultaneously witholding a shuttle feed mechanism 30 from the paths of film 14 and expanding the gate 15 during either rapid rewind or initial film threading. Supply spool 42 may be driven in forward or rewind direction when solenoid 57 is energized to engage driven roller 60 with reel 42 by means of lever 64, link 65 and arm 62 pivoted at 63. Roller 60 is coupled to roller 61 on a shaft 48 on which is fixed a gear 46 normally meshing with a reversely driven gear 45. Film threading is initiated by use of lever 49 to axially shift shaft 48 against spring 52 until gear 46 meshes with forwardly driven gear 47 and micro-switch 83 is actuated to energize solenoid 57. Roller 60 is then swung to engage spool 42 and film is fed to the opened gate 15 where the shuttle feeds the film. Gate 15 comprises a fixed part 16 and a spring- loaded pressure plate mounted on pins 22 extending from a portion 23 of an L-shaped bracket 24 whose other portion 25 is slidably supported on a wall 26 of the projector. Solenoid 57 is mounted on portion 25 such that bracket 24 and the pressure plate are shifted to an open gate position by energization of the solenoid to operate roller 60. Portion 25 also carries an arm 77 whose hook end engages shuttle 30 to prevent the in-and-out motion imparted by cam 38. Reverse winding of spool 42 is initiated after projection ends when increasing tension pivots a track section 86 to actuate a micro-switch 84 which then energizes solenoid 57 to open gate 15 and drive spool 42. Since shaft 48 is now in the normal position with gears 46, 45 meshing, reverse drive to spool 42 takes place.

Abstract: 1489220 Testing tyres COMMISSARIAT A L'ENERGIE ATOMIQUE 19 Dec 1974 [27 Dec 1973] 55016/74 Heading B7H To determine whether or not a tyre has defects arising from separation of the carcass cord fabric plies from the rubber compound in which the plies are embedded, a gamma-ray emitting radioactive gas is injected under pressure, e.g. of at most 12 bars into the carcass plies, and the radiation emitted by the gas within the tyre is detected, the level of detected radiation being indicative of the defect state of the tyre. In a first method, a nitrogen/xenon-133 mixture at a pressure of 8 bars is injected into the tyre at one point adjacent a head or at a plurality of points in a radial section. The tyre is then rotated about its axis, which is horizontal, past stationary detector where the injection is at a single point, or past one or more detectors where the injection is at a plurality of points. The mixture has an activity concentration of 3MCi at 8 bars (or 0À375 MCi/litres at normal temperature and pressure). In a second method, the mixture is injected at one or a plurality of points on a radial section into the stationary tyre at the same time as a detector which is spaced, e.g. at 180 degrees, from the point of injection effects a radiation count, and the latter is indicative of substantial or minimal separation of the cord fabric plies from the rubber compound. The detector preferably comprises a scintillation probe with or without a lead collimater, and the detection may be effected using an internal lead shield 29.

The stages B1-B9 of a binary counter 40 are coupled as shown to the NAND gates G1-G11 supplied with second inputs from a second counter B10-B18 acting as a pulse generator, thereby producing an output pulse at terminal 46 having a duration proportional to the number stored in the counter. In practice the addition of consecutive pulses from the second counter results in the production of a pulse of the required length followed by further shorter pulses (Fig. 3b, not shown); the latter are removed by the action of bi-stable circuits B19- B22 which also suppress alternate ones of the long pulses. In the intervening periods further long pulses are produced at the output terminal 46, these having a duration determined in a similar way by the inputs on lines 52-64. The output pulses may be used to gate the output of a pulse generator, thereby producing a number of pulses equal to the number stored in the counter B1-B9 followed by a number of pulses corresponding to the input on lines 52-64 and so on.
