Title: Improvements in or relating to generators for the electrical ignition of a projectile
IPC: H02K39/00
Filed: 1960-10-28
Abstract: 963,484. Ammunition fuzes. BREVETS AERO-MECANIQUES S.A. Oct. 28, 1960 [Oct. 30, 1959], No. 37160/60. Heading F3A. [Also in Division H2] In an ignition device for a projectile a coil 7 of a generator 1 is normally short-circuited through a rectifier 14, a finger 13 and a part 16 of spring-loaded wiper contacts 18, 19. A permanent magnet core 9 is normally held stationary by a finger 12 pressing against a thin sheet 23. The finger 13 normally rests in a recess 17 of the part 16 thus holding the wiper contact arm 18 against the torque of a spring 15. When the projectile is fired inertia causes the core 9 to slide and the finger 12 thereon to puncture the sheet 23, and a voltage is induced in the coil. The contact between finger 13 and the wiper part 16 opens and a condenser 2 is charged via the rectifier 14. If the wiper arm 18 is permitted to rotate until it contacts a finger 22 on a primer 23 (Fig. 3, not shown), then closure of percussion contacts 20, 21, on impact with a target will discharge the condenser through the primer and fire the explosive charge of the projectile.

Abstract: 1437985 Resolving priority conflicts HONEYWELL INFORMATION SYSTEMS Inc 8 Aug 1973 [5 Oct 1972] 37695/73 Heading G4A Priority conflicts for the main store access by a central processing unit 6 (Fig. 1), buffer store 8 or input/output control unit 7 are resolved in a main storage sequencer 4 by delaying by various predetermined amounts in variable delay lines 11, 12, 10, coupled to the requesting unit, a signal indicative of a request for service, the delay line being connected to a priority resolver 9 which assigns access to the device associated with the first received signal. If for example it is required to write information into the store from the input/output controller, address signals are applied to the memory via an address switch (411, Fig. 4A, not shown) and data is transmitted via a write switch (428) to a bus (434). Parity is checked in parity checkers (408, 409). Write mask information is similarly fed to a parity checker (407) and via a switch (415) to bus (433). The request signal is fed to a priority resolver which determines whether the requested memory module is available in which ease a gate (308, Fig. 3, not shown), associated with the requested module, is enabled to pass the request signal via a receiving unit (351) to an acknowledge unit (355) which generates a signal indicating that the request is being processed, a memory busy signal and a main storage sequence busy signal also being generated. The acknowledge signal is fed back to the requesting unit. A lock out unit (321) prevents a further unit being accessed. Requests for memory are under the control of a central clock (not shown) in the central processing unit.

Abstract: 884,770. Frequency discriminators. GENERAL ELECTRIC CO. Ltd. Nov. 13, 1959, [Nov. 26, 1958], No. 38219/58. Class 40(5). A frequency to be measured, e.g. 15,000 mc./s. is amplitude modulated at 2 by a frequency, e.g. 60 mc./s., supplied by an oscillator 3. The output of the modulator 2 is transmitted over a long length of waveguide 4 and demodulated at 5 to provide a modulation signal whose phase is dependent upon the frequency to be measured. This signal is amplified at 6 and supplied to phase detectors 7 and 8 where it is compared with reference oscillations from the oscillator 3, the reference oscillations having a 90 degrees phase shift before being supplied to the phase detector 8. The signals supplied by the phase detectors 7 and 8 are amplified and utilized to control the horizontal and vertical deflection respectively in a cathode ray tube 12. It is arranged so that with no signals from the phase detectors a bright spot is produced on the screen in a "normal" spot position, and signals supplied by the phase detectors cause the spot to take up another position, the angle between an imaginary straight line passing through this position and the "normal" spot position and a datum line passing through the normal spot position being a measure of the frequency. The imaginary line may be produced as a visible trace by periodically interrupting the signals supplied by the phase detectors. In a modification the end 13 of the waveguide is short-circuited and the waveguide fed from the modulator via a circulator to which is connected the detector 5, in this case the waves passing twice along the waveguide. In a further arrangement a directional coupler is used instead of a circulator.
