Title: Identification of low flying aircraft by sound - involves eliminating doppler ambiguity by variable time sampling
IPC: G01S15/87
Filed: 1973-05-22
Abstract: The identification of the type of low flying aircraft is made by a fine analysis of the audible spectrum picked up by a microphone. Peaks in the spectrum correspond to turbine blade noise, etc., and can be unique to an aircraft. Ambiguity caused by Doppler shifts are eliminated by sampling the input waveform at variable times according to the speed which must be known. The speed can be obtained by radar or by a triangular net of microphones. Preferably the inputs from all microphones being used for spectral analysis, for several channels could be processed at once, are passed through sample-hold units E1V1 and then through a further sampler E2V1 driven by a shift register R. The outputs are time multiplexed and pass through an analogue to digital converter and thence via gates to registers RV1. The analyser is not shown.

Title: Pressure differential ship log - has static and dynamic pressures sensor, transducer and integrator
IPC: G01P5/14
Filed: 1974-05-08
Abstract: A pressure differential log to measure the speed of a ship and by integration of distance covered has an under surface pressure sensor with two pressure tappings to measure static and dynamic pressures. A pressure transducer converts the pressure differential into an electrical signal.

Title: Digital phase locked loop for navigation systems - is designed specially for microwave systems such as TACAN and includes a/d converter and sequence register
IPC: H03L7/00
Filed: 1975-12-09
Abstract: The phase-locked loop generates clock pulses synchronised with the passage through zero of an input data signal, e.G. for use in navigation systems. An A/D convertor continuously converts the input signal into a digital signal which is checked and stored by a memory when it receives a clock pulse. When a given digital signal count is reached an instruction sequence register reads out the count in synchronism with the zero passage of the input signal and generates a carry pulse at the end of the count. The carry pulse is fed to a pulse generator to produce a synchronous output clock pulse which leads or lags the zero passage of the input signal by the counting time of the instruction sequence register. A circuit feeds the output clock pulse to the memory which ensures this pulse and a second output clock pulse are synchronized with the zero passage of the input signal.

Abstract: 1480983 Photo-copying apparatus G RITZERFELD 25 Sept 1975 [11 Feb 1975] 39271/75 Heading G2A  A photo-copying apparatus has a first imagebearing original, and a second image-bearing original partially masking the first, and a further masking means for the first original, the two originals being relatively displaceable so as to vary the gap between the two masking portions through which the visible portion of the first original is copied. The arrangement is similar to that disclosed in Specification 1481148 but in the present case a second original acts as one of the masking means. The two originals are supported on a glass plate 1, heading original 25 below and partly masking the line original 26. These are each held by a clamping device, so that either can be moved to the left or right with respect to the other. Thus any lines on the line original can be brought alongside the heading original. A transparent strip 28 carrying a number of opaque masks such as at 31 can be wound across between reels 29 and 30, and this may be manually controlled so as to bring any of the masks into any position. The transparent strip 28 itself may carry material which is also projected and copied.
