IPC: H03K5/06
Filed: 1964-12-17
Abstract: 1,095,842. Pulse radar. COMPAGNIE FRANCAISE THOMSON HOUSTONHOTCHKISS BRANDT. Dec. 17, 1964 [Dec. 17, 1963], No. 51458/64. Heading H4D. In a pulse compression radar wherein the transmitter produces a radio frequency pulse of constant amplitude and relatively long duration # which is linearly modulated in frequency as a function of time with a deviation much greater than 1/# and equal to 1/ #2 , where # 2  is the duration of the compressed pulse, a supplementary modulation is added within duration T by a modulating signal of which a parameter is caused to vary as a function of time and the transmitter output signal is fed to a filter of bandwidth 1/# 2  or the receiver incorporates such a filter. The modulating signal may include a train of sub-pulses of variable duty factor (by variation of sub-pulse duration, by variation of sub-pulse repetition rate, or by both) or may produce a supplementary frequency modulation at a rate of the order of 1/# 2  and of variable index. It is stated that the time side-lobes in the compressed pulse are reduced and that the effects of Doppler frequency shifts are compensated. With a supplementary frequency modulation, Fig. 5c, the rate is greater than 1/# 2  and the index is a minimum at the ends of the long pulse. The transmitter may utilize klystrons and a gain-controlled amplifier.

Title: A receiver for the reception of pulses modulated on a carrier wave
IPC: H04L27/06
Filed: 1970-10-30
Abstract: 1,260,976. APC for pulse modulation receivers. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 30 Oct., 1970 [4 Nov., 1969], No. 51712/70. Heading H3A. A receiver for the reception of pulses modulated on a carrier wave having pilot frequencies f 1 , f 2  (Fig. 2, not shown) operates by the restoration of clock and carrier signals from the incoming signal and comprises two APC loops 25, 26 each including an oscillator 27, 28 and phase discriminators 29, 30 in which oscillator 27 is tuned to f 1  or f 2  and the output of discrimi - nator 29 containing modulation products f 1  +f 2 , f 1  -f 2  is applied to loop 26 containing oscillator 28 tuned to f 1  + f 2  and to a selective filter 39 to derive a frequency f 1 -f 2 . Filters 39 may be replaced by another APC loop. The APC loops serve to reduce any phase error produced by input selective circuits of the receiver consequent to the input signals undergoing a frequency shift in the transmission. In the receiver of Fig. 1, an incoming pulse carrier, e.g. orthogonally modulated is demodulated by push-pull devices 2, 3 to which locally generated carrier signals are applied in phase and in quadrature and the outputs are sampled at 7, 8 by clock signals before application to output devices 9, 10. The carrier and clock signals are derived from incoming signal by unit 11 containing the APC loops 25, 26, one output being divided at 14 to obtain a local carrier frequency ¢ (f 1  +f 2 ) and the other output (f 1 -f 2 ) being applied to a ring counter 16 formed by shift registers 17-19 via a pulse shaper 15 and an OR gate 23 to obtain a clock pulse, e.g. of frequency <SP>2</SP>/ 3  (f 1 -f 2 ). To ensure that the incoming and locally generated carriers are in co-phase, change of state decoders 20, 21 are provided. Similarly any phase ambiguity in the sampled demodulated signal and the local clock signal is corrected by a zero-passage detector 24, inhibitor and OR gates 22, 23.

Abstract: 1275117 Gas turbine jet engines; reheat equipment SOC NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION 23 Oct 1969 [24 Oct 1968] 51921/69 Heading F1J A gas turbine jet engine having reheat combustion equipment comprises a main combustion chamber supplied with a combustible mixture, also means to inject reheat fuel downstream of the turbine, means being provided to enrich the combustible mixture temporarily so as to produce in the combustion chamber a flame which passes through the turbine so as to effect reheat ignition; means are provided whereby the combustible mixture is temporarily weakened immediately before the temporary enrichment of the mixture. In Fig. 2 a device is provided in the linkage 5a between the throttle control lever 6 and the lever 5b of the main fuel control unit 5. A spring- loaded piston 4c in cylinder 4a is connected by rod 4e and link 4f to the linkage 5a. When the throttle lever 6 is moved to the reheat position, the reheat fuel pump 7 is started up and the contact 8 closes which causes electromagnetic valve 9 to open, the opening movement being delayed by means of a device 10 such as a bi-metallic device. When the valve 9 opens, fluid under pressure passes to the piston 4c thence passing through a restricted outlet. The piston moves to the right against opposing action of spring 4d and causes deceleration of the engine. When the device 10 opens, the valve 9 is de-energised and therefore closes; the piston 4c is moved to the left and the control unit 5 acts to cause temporary enrichment of the fuel/air mixture in the main combustion chamber thus resulting in passage of flame through the turbine and ignition of the reheat fuel. In Fig. 3 the pistonrod 4e first acts to reduce the compression of the spring 5c of the governor device 5d so acting to produce a weak fuel/air mixture. Upon operation of the device 10 the piston is moved to the left so acting to increase the compression of the spring 5c so causing an enrichment of the fuel/air mixture supplied to the main combustion equipment.

Abstract: 1517869 Image encoding apparatus INTERNATIONAL BUSINESS MACHINES CORP 20 Dec 1976 53034/76 Heading H4P Data in the form of a stream of bits representing picture elements (pels), derived from the raster scanning of a document 1, is stored in compressed form in a store 8 which can be accessed so that the data pertaining to the stored document can be transmitted to a receiver 13 or can be expanded in a decompressor 9 for plotting or printing by a plotter 10 or for display on a display unit. The required compression is effected by passing the original bit stream through a pel stripper 3 where bits are removed to leave a processed bit pattern in which the bits represent predominantly single-pel-width strokes constituting either the outlines or the centre lines of characters. A segment follower 6 detects contiguous bits and produces a series of segments representing the tracked strokes. Each segment is coded in an encoder 7 into code words representing the shape of the segments and code words representing the end points of the segments, the segment bit thus produced being stored in the store 8. The stripping process is described with reference to Fig. 2 (not shown), whilst the constraints which determine whether a pel is or is not stripped from the original bit stream are described with reference to Figs. 5 and 6 (not shown). Suitable arrangements for the units 3, 6 and 7 are described with reference to Figs. 7 to 13 (not shown).
