Title: An improved clockwork fuze for projectiles
IPC: F42C9/04
Filed: 1943-04-02
Abstract: 583,472. Projectile fuzes. SCHWEIZER, P. April 2, 1943, No. 5345. [Class 9 (i)] Relates to clockwork fuzes of the kind having two oppositely-rotating members driven at different speeds and having gapped peripheries, the gaps of which are relatively displaced in the setting of the fuze and permit the release of the striker by a centrifugally-operated bolt only when they reach coincidence during the running-down of the clockwork. According to the invention, a spring-urged lever which locks the striker-release bolt is itself locked by a second or safety lever which is held in locking position by a spring until the fuze is set, and is released by centrifugal force, both levers having projections which coact with the gaps in the two rotating members. The axial striker 3 is held by a centrifugally-operated bolt 14, itself locked by the entry of the semicircular end 35 of a rock-shaft 12 into a notch 13 in the bolt. A lever 16, controlled by a spring 17, is mounted in the other end of the shaft 12. This lever is held in the " safe " position shown in Fig. 3 by a second lever 22, rockable' on a pivot 23 by centrifugal force, against the pull of a spring 24, to release the lever 16. The latter has upwardly and downwardly extending projections 18, Fig. 8, and the lever 22 has similar projections 27. The levers lie between two rotatable members 5, 11, the former being a disc driven by the clockwork and the latter a ring driven at reduced speed and in the opposite direction by gearing 6, 7, 9, 10, the pinion 6 being integral with disc 5. The disc has a flange 6a in which a gap between the ends 25, 26 and the ring 11 has a gap between the ends 30, 31. In the zero or safe position, the two gaps are in register and projection 27 on lever 22 lies against the end 25 of flange 5a. 'When the fuze is being set, the gaps move apart, the disc 5 being rotated clockwise (Fig. 3) and the ring in reverse direction, until a set position, such as that shown in Fig. 6, is reached. In these rotations, the bevelled flange-end 26 engages the lever projection 27 and moves the lever outwards, so as to disengage the lever 16 which is, however, held against outwards movement by the engagement between the ring 11 and the lever projection 18. When the shell is fired, the clockwork.is started in known manner, and the discs are rotated back until the gaps return to registering positions. Centrifugal force maintains the lever 22 in its outward position, but the lever 16 is moved through the gaps by centrifugal force aided by the spring 17 ; the detent 35 is thereby moved out of the notch 13 in the centrifugal bolt 14, which is then moved outwardly to release the striker 3.

Title: Communication system with at least one repeater station using the same carrier freuqency
IPC: H04B7/15
Filed: 1973-02-05
Abstract: 1377334 Radio signalling BENDIX CORP 5 Feb 1973 [23 Feb 1972] 5645/73 Heading H4L  In a communication system including at least one repeater station and two remote stations the remote stations communicate directly or via the repeater on a press-to-talk basis using pulse modulation and the same carrier frequency. Repeater.-A relaxation oscillator 3, Fig. 1, provides a train of pulses in which the time between the pulses is varied in accordance with the output of a discriminator 9 for application via a delay 4 to trigger a monostable 5. The output of monostable 5, consisting of pulses of fixed amplitude and duration, is supplied to key the transmitter 6. Signals received at 7 are limited at 8 and compared at 9 with a pulse from delay 4 and generator 5 and if the received pulse coincides with the transmitted pulse there will -be no output to vary the free-running oscillator 3. However, if the received pulse starts before or after the transmitted pulse, the output of oscillator 3 will be varied accordingly. A received pulse beginning before and ending after the transmitted pulse will produce a change proportional to the departure from coincidence of the mean points of the two pulses. Remote station.-With the push-to-talk switch 114a, 114b operated, Fig. 4, the spacing of pulses generated by a relaxation oscillator including a unijunction transistor 13 is varied in accordance with the microphone input supplied via amplifier 102, capacitor 14 and resistor 125 being selected to make the free-running pulse rate equal to that of the repeater. The output of the relaxation oscillator is supplied to a pulse generator 106 which produces corresponding pulses of standard width which are applied to key the transmitter 108. In the receive position, the output of receiver 110 is integrated at 116 and supplied via amplifier 118 to the headphones.

Abstract: 979,429. Rotary-piston internal combustion engines. K. WELM. Feb. 17, 1961 [Feb. 17, 1960], No. 6032/61. Heading F1F. A rotary-piston I.C. engine comprising a cylinder G, Fig. 2, and a rotary piston 1 mounted on a central shaft 2, includes at least one sealing member mounted in the cylinder wall and resiliently urged into sealing contact with the piston to define on opposite sides of the piston a combustion chamber 4 and a cooling air chamber 4a. The chamber 4 is fitted with alternative inlet ports 13, 15 for fuel-injection or petrol-air mixture suction respectively and a spark-plug 16 and the chamber 4a with an air inlet port 3. As shown in Fig. 2, a spring-urged, pivoted sealing member 5, fitted with spring-urged sealing strips 20, 21 engageable with the piston 1 and a cylinder recess R respectively and other sealing strips (not shown) with the cylinder end walls is retractable into the recess R. In operation, the surface area of the piston 1 on which the combustion gases act after ignition, progressively increases until the exhaust port 17 is opened. After the closure of the port 3 by the piston, the pressure in the chamber 4a increases sufficiently to urge the sealing member 5 against its spring away from the piston to permit cooling air into the combusion chamber. A second sealing member 5<SP>1</SP>, Fig. 4, oppositely handed to the sealing member 5 may be fitted to define a compression chamber between itself and the piston. In another embodiment, the pivotally-mounted sealing member 5 is replaced by a spring-loaded strip reciprocable in a slot-like recess in the cylinder. A plurality of pistons mounted on a common shaft may be angularly disposed with respect to each other and rotate in separate side-by-side cylinders.
