Abstract: 1326054 Electronic timepieces CITIZEN WATCH CO Ltd 18 Aug 1970 [18 Aug 1969 20 Aug 1969 25 Aug 1969] 39810/70 Heading G3T [Also in Division H1] A battery powered electronic timepiece, wherein a balance wheel 32 (Fig.1) drives a gear train and permanent magnets 135, 136 on the balance wheel co-operate with drive and sensing coils 31, 30 connected in a transistor oscillator circuit to drive the balance wheel, comprises at least one thin film adjustable resistor element 50 whereby the amplitude of oscillation of the balance wheel can be adjusted to a desired value. The resistor element 61 (Fig.3) of resistor 50 together with connecting leads also a further resistor 55, are formed by vapour deposition or other printed circuit techniques. As shown sections d 1  d 2  d 3  of element 61 are shunted by a conductor strip a and are thus ineffective while sections U 1  U 2  are effective in the drive circuit. In order to adjust the effective value of resistance of element 61 and hence the amplitude of oscillation cuts are made successively in the shunting strip a to form further gaps c whereby sections d 1  d 2  etc can be added sequentially and the effective resistance increased stepwise. Alternatively gaps may be cut in the lateral strip "b" as described with ref. to Figs. 14, 15 (not shown). If it is desired to decrease the said resistance the gaps c may be bridged with conductive paste. The resistor 55 may be adjusted if desired by making one or more lateral cuts extending across part of its width only. Various conventional transistor oscillator circuits utilizing an adjustable resistor(s) substantially as Figs. 1 and 3, are illustrated in Figs. 2, 7, 8, 13, 14 and 15 (not shown). A modified adjustable resistor element having paralleled sections is illustrated in Fig. 6 (not shown). Each coil may function alternately as a drive and a sensing coil.

Title: Speed-Actuated Switch for Missiles.
Inventor: RAWCLIFFE ANTONY GEORGE
IPC: F15C1/00
Filed: 1966-09-12
Abstract: 1,198,628. Projectile fuzes. BRITISH AIRCRAFT CORP. Ltd. 11 Dec., 1967 [12 Sept., 1966], No. 40744/66. Heading F3A. [Also in Division F1P] The warhead of a rocket or guided missile is armed, when the missile reaches a particular speed, by means of fluid derived from the propulsion motor of the rocket or missile, which fluid enters a pure fluid switch 22 through a passage 28, whence it is deflected into one of two outlet passages 18 and 20 leading to each side of a piston 12 slidable in a cylinder 10, the switch having a control channel 30 connecting with a static tapping which can be a hole 34 in the sidewall of the missile, and a control channel 32 connecting with a ram inlet port 36 which can be a tube projecting ahead of the missile. The area of the hole 34 and the pressure of the fluid in passage 28 are adjustable. Initially, the biasing effect of the channel 30 exceeds that of the channel 32 and fluid from the passage 28 is deflected into the chamber 70 whence a detonator 40 is maintained at a safe distance from an explosive-filled magazine tamping 42. At speeds above the particular speed, the biasing effect of the channel 32 exceeds that of the channel 30 and fluid is deflected into the passage 20 whence spring-biased pins 50 and 52 are lifted out of engagement with the piston which then moves to align the detonator and magazine tamping. Flexible clips 62 and 64 enter notches 66 and 68 to lock the detonator in the armed position. In a modification (Fig. 2, not shown) the fluid leaving one or other of the outlet passages of the pure fluid switch is used in a second switch to deflect fluid from the motor into one of two passages leading to each side of the piston. The piston actuates an electric switch in a fuse circuit.

Title: Improvements in and relating to setting devices for the throttle valve operating mechanisms of engines
Inventor: GUSSENBAUER HEINRICH
IPC: F02D11/10
Filed: 1967-09-13
Abstract: 1,247,853. Regulating. H. GUSSENBAUER and K. GUSSENBAUER. Dec. 6, 1968 [Sept. 13, 1967], No.41776/67. Heading F1B. A throttle operating shaft 5 can be held set at any angular position by holding coil springs 18, 7, operation of the clutch or brake pedal releasing the spring 7 to permit the shaft to return to idling position. Shaft 5 passes through a stationary drum 2A and carries a second drum 2B surrounded by the spring 7, the drum 2B being rotatable with shaft 5 but slidable axially thereon. A third drum 15 freely rotatable on shaft 5 and surrounded by spring 18 is carried around by a flange 4 on drum 2B carrying balls 8 engaging recesses 16. Spring 7 has one and enclosed in the drum 2A and the other end 7B enclosed in a slot 11 in a spring-loaded slidable sleeve 10, a projecting pin 12 of which is actuated by a cam 13A, 13 on a slide 3, Fig. 5, which has slots 22 in which the ends of spring 18 engage. During normal operation pin 12 is engaged by cam face 13B whereby sleeve 10 is rotated to loosen spring 7 and free the drum 2B and to allow free rotation of shaft 5. Simultaneously the slots 22 hold the ends of spring 18 apart so that drum 15 is free on the shaft 5. To clamp the throttle shaft in a predetermined position, Bowden cable 20a is actuated to move slide 3 to the right, whereby pin 12 moves to a recess in cam 13A, 13B, to cause spring 7 to tighten and hold drum 2B and slots 22 also move the ends of spring 18 together and tighten it on drum 15 and hold it stationary. Operation of the clutch or brake pedals while the shaft 5 is held clamped actuate cables 20B or 20C, to move slide 3 further to the right whereby cam face 13A rotates sleeve 10 to slacken the spring on drum 2B and permit shaft 5 to return to the idling position, drum 15 remaining held clamped by spring 18. If the accelerator is depressed further while the shaft 5 is clamped, balls 8 are forced out of recesses 16 and move sleeve 10 to the left, oblique teeth 10A thereon engaging stationary teeth 9A to rotate the sleeve 10 to loosen the spring 7 and free the shaft. On release of the pedal, shaft 5 returns until balls 8 re-engage in the recesses 16, whereby sleeve 10 returns and spring 7 reclamps the shaft 5 in the original position. In a modification the springs 7, 18 are controlled by solenoids 25A, 25B, Fig.10, the circuits of which are controlled by a manually operated switch 37. Switches 31, 33, 35 operated by clutch, brake and accelerator pedals de-energize solenoid 25A to loosen spring 7 and cancel its clamping action.
