Filed: 1975-05-22
Abstract: 1475113 Wire-guided missiles BRITISH AIRCRAFT CORP Ltd 22 May 1975 [5 June 1974] 25048/74 Heading F3A [Also in Division H1] A switch for incorporation in a wire-guided missile comprises a coiled element one end of which is adapted for attachment to a launcher for the missile so that when the missile is launched and a predetermined length of the coiled element has been payed out a switch member is operated automatically. The coiled element may be the guidance wire. In one embodiment, Figs. 1 and 2, a main winding 2 of the missile guidance wire is carried on a spool 1 and subsidiary windings 7, 8, 9 are carried by bobbins 4, 5, 6. Each bobbin comprises four arcuate sections 10, 11, 12, 13, Fig. 2, which are maintained in position on the spool by the subsidiary windings. One section of each bobbin is provided with respective tongues 14, 15, 16 which pass, respectively, through slots 17, 18, 19 in spool 1. A shaft 20, rotationally biased by a spring 21 towards a final position, is capable of being held in intermediate positions by angularly spaced drum latches 22, 23, 24, which co-operate with each of the bobbin tongues in turn. A wiper 28 of an electrical rotary switch 29 is mounted on one end of the shaft 20. When the missile is launched, the guidance wire is taken from bobbins 4, 5, 6 in turn and then from the main winding 2. As the last turn of each subsidiary winding is payed out, the bobbin sections are released and are immediately jettisoned thereby allowing shaft 20 to drive the rotary switch 29 to its next position. In another embodiment, Fig. 3, a bush 52 is fixed to a rotary shaft 51, and bushes 53, 54 are rotatably supported on the shaft. The bushes and a spool 50 are locked together by pairs of keys 55, 56, 57 which are retained in position by subsidiary windings 64, 65, 66 of the guidance wire. The bushes are provided with pins 58, 59, 60, respectively, projecting into arcuate slots 61, 62 in adjacent bushes and into a similar slot 63 in the spool 50. When the guidance wire is payed out, the keys are uncovered and jettisoned and the shaft 51 rotates to intermediate positions determined by the pins and arcuate slots.

Abstract: 1421383 Shutter control SEIKO KOKI KK 25 May 1973 [26 May 1972] 25170/73 Heading G2A A camera shutter mechanism comprises a blade operating device 18, 28 biased to move from an inoperative position in a blade opening direction, a delay device 20, 27, which is spaced from and engageable with the operating device to resist movement of the latter in the blade opening direction and control the blade opening speed, a blade closing member 34 which is urged from an inoperative position in a blade closing direction, and control means for setting and releasably holding the blade operating device and blade closing member in their inoperative positions. Fig. 1 shows the mechanism prior to exposure. In operation release plate 2 is manually depressed against the action of a spring 6 and engages a detent 17, rotating it out of engagement with a setting member 8. Member 8 rotates clockwise under the influence of a spring 13 and disengages a pin 9 from the member 18 which also rotates clockwise under the influence of a spring 19. After a small degree of rotation member 18 engages one end of a lever 27, the other toothed end of the wheel meshing with gearing on a wheel 20 which is biased to rotate anti-clockwise by a spring 21. Rotation of the wheel is limited by the abutment of portions 20a and 20b with a stop 24, which retains the lever 27 spaced from member 18. As member 18 rotates at a controlled speed it permits blade operating member 28 to rotate under the influence of spring 31 to open the blade. Initial depression of the plate 2 also disengages an end portion 2f of the plate from a pin 36a mounted on the blade closing member 34. The member 34 rotates a small distance before it engages an abutment 38a on a control lever 38 which is held in position by an electromagnet 42. After a time interval determined by the ambient light conditions the electromagnet is de-energized, lever 38 is released and member 34 rotates to engage and rotate the operating member 28 against the force of spring 30 and close the blade. A lamp is provided which indicates whether the ambient light is above or below a predetermined level. Also a locking lever 41 prevents full depression of the release plate 2 if the battery powering the electromagnet, or the electromagnet is not functioning correctly.
