Title: Photographic shutter with electronic timing device
IPC: G03B7/083
Filed: 1969-10-23
Abstract: 1,221,277. Electronic shutter timing. PRONTOR-WERK ALFRED GAUTHIER G. m.b. H. Oct.23, 1969 [Dec. 12, 1968], No.51885/69. Heading G2A. In a photographic shutter, a lug 3a on the shutter blade driving ring 3 strikes against the end of a two-part toggle lever 7, 9 during the opening movement, and is locked thereby; the toggle lever is held by an electromagnet 16 during the exposure period as determined by an electronic timing device 17, after which the lever is released and pivots so as to release the ring 3, thus enabling the opening movement to be completed and the closing movement made. As shown, the shutter blade ring 3 is driven clockwise by the driving disc 1 and pawl 2, to open the shutter blades 4, from the cocked position of Fig. 1 (not shown). A lever 7, pivoting on a fixed pin 12, has one arm 7a carrying an armature 8 which is held against an energized electromagnet 16 in opposition to the action of a spring 13. When the release mechanism 5, 6 is actuated, disc 1 is released and ring 3 is driven clockwise. The lever 6 closes a switch S 1 , which energizes the electromagnet 16 to hold the armature 8 against it. The levers 7 and 9 now form a rigid system, and when lug 3a on ring 3 strikes the end of lever 9 just before reaching its reversal point, it can go no further, and thus remains locked in that position shown in Fig. 2, the shutter blades now being open. In this position a pin 3c on ring 3 actuates a switch S 2  which initiates the timing action of an electronic circuit 17. After a predetermined time has elapsed, the electromagnet 16 is de-energized, so that lever 7 is pivoted away from it by spring 13, position of Fig.3. Levers 7 and 9 are no longer rigid together, and crank about pin 14, so that lug 3a is no longer locked, and ring 3 can complete its opening movement, and then reverse under the reciprocating action of pawl 2 in a shutter-closing movement. In so doing, a pin 3b on ring 3 engages against lever 9 and pushes it back into the Fig.1 position, so that armature 8 again rests against magnet 16.

Filed: 1968-11-04
Abstract: 1,185,270. Protective arrangements. UNITED STATES ATOMIC ENERGY COMMISSION. 4 Nov., 1968 [13 Dec., 1967], No. 52187/68. Heading H2K. An overload protective circuit comprises non-linear conductor means, e.g. a diode 16, in series with circuit interrupting means 18 between input and output terminals 10, 12, an integrator 20 responsive to the voltage drop across the conductor means which provides a voltage drop substantially independent of the current therethrough, and an activator 28 operative when the time integral of the voltage drop reaches a threshold level to effect operation of the means 18. The conductor means may comprise oppositely poled parallel diodes 14, 16 and protect a capacitor in a high energy pulse circuit. The integrator 20 may be a circuit including an amplifier and a feed-back capacitor, or a saturable core reactor or a thermal resistive element. If a resistive element is used for the integrator, then the activator is a thermally responsive element which operates the means 18. Fig. 4 (not shown) illustrates an arrangement in which several of the protective circuits are used in protecting a capacitor bank. In this case each thermally responsive element is an explosive charge. A high rupturing capacity fuse may be provided in series with each circuit.
Patent GB-524204-A (GB)
Abstract: 524,204. Gyroscopic apparatus. NISBET, R. H., HARDING, W. G., and SPERRY GYROSCOPE CO., Ltd. Jan. 23, 1939, No. 2227. [Class 97 (iii)] The rotor case of a cardan mounted directional gyroscope is caged, i.e., set in relation to the cardan frame, and held there when desired, by means applying a torque to the case, and by frictional means providing a torque preventing unassisted movement of the cardan frame about a vertical axis ; means for setting the gyroscope to a desired course may be provided. As shown, a directional gyroscope of the type described in Specification 497,584 has a vertically slidable caging plate 12 on the cardan ring 2, and a non- rotatable ring 22 which is vertically movable to engage frictional members extending from the ring 2, both being operable by pushing a knob 7. The spindle 7<SP>1</SP> of the knob 7 carries a ball 17 engaging in a member 18 mounted on a pivot 19 and carrying pins 18<SP>1</SP> ; the pins, as the knob is pushed, ride over the surfaces of arms 20 mounted on pivots 21, to tilt the arms and rest in notches 20a. The arms 20 have pins 20<SP>11</SP> engaging a groove in the ring 22, and raise the ring to engage leather-covered ends .23a on legs 23<SP>1</SP> passing through the cardan ring 2. Rotation of the ring 22 is prevented by legs 221 extending into holes in the main frame. The legs 23<SP>1</SP> extend from a member 23 engaging a lever 24 mounted on a pivot 25 carried by the cardan ring 2 ; this lever is connected by a spring 26 to a lever 27 mounted on the pivot 25 and engaging a bolt 28 on the caging plate 12. Lateral guides 13, 13<SP>1</SP> on the ring 2 permit movement of the plate 12 vertically against the upward pull of springs 14. The plate 12, Fig. 2, has hardened steel strips 16, 16<SP>1</SP> which alternatively engage pins 11, 11<SP>1</SP> extending from the rotor case 1 to turn the case about its pivot axis A A if the rotor axis is not horizontal. Setting may be effected by rotation of the knob 7 a crown wheel 9 on its spindle being in mesh with a gear 10 on the cardan ring 2 when the knob is pushed in. The resilience provided by the spring 26 enables the pins 18<SP>1</SP> to ride over the lip of the notch 20a, and applies the actual torque to the gyroscope during setting, thus reducing the forces exerted on the bearings. The ring 22 may, in a modification, be pivoted on the pins 20<SP>11</SP>, and a leather &c. covered ring may be attached to the bottom ends of the legs 23<SP>1</SP> ; both rings may have conical engaging surfaces. In a further modification, the ring 22 may be omitted, and the pins 20<SP>11</SP> may engage a ring attached to the legs 231.
