Patent GB-2078455-A (GB)
Title: Phased waveform generation
IPC: G06F1/03
Filed: 1981-05-19
Abstract: A reference waveform of a frequency determined by a variable oscillator (3) is generated by synthesis from digital data stored in a memory (1), via a digital to analogue converter 20 and a filter 22. A variable waveform whose phase can be varied relative to the reference waveform is similarly generated from a memory 2, converter 21 and filter 23. The phase relationship is varied by appropriate selection of the relative position of address of the memories (1,2) and by a system of latches (17,19) and dividers (4,5). <IMAGE>

Title: Lock control mechanism
IPC: G06K7/08
Filed: 1981-07-02
Abstract: The invention relates to a device for controlling an element for locking and unlocking a lock particularly on a car, comprising an independent emitter (4) and a receiver (12) connected to the lock. The emitter comprises an emitter of a coded message and a transmitter for it the receiver comprises means for reception of the said coded message, means for comparing it with a memorized standard, means to emit a signal in the case of agreement between the said messages, and an amplifier of the said signal. The emitter (14) comprises a pair of contacts (7, 8) for electric connection to at least one pair of contacts (5, 6) connected to the terminals of the supply source (1) of the receiver (3). The arrangement is such that the terminals are in contact when the receiver (3) and the emitter (4) are opposite to one another. Thus the emitter needs no power supply of its own. As shown a switch (2) is in the receiver and is actuated by a magnet in the emitter. Transmission of the emitted signal is by optical means. <IMAGE>

Patent GB-2105063-A (GB)
Title: Photographic method used in making models
Inventor: SAVORY J
IPC: G03F1/88
Filed: 1982-08-13
Abstract: This invention relates to model making and to a method for applying detail to a surface of a model blank. A photographic representation of an article surface to be modelled (Fig. 1) is made and from the range of tones present (tones 11 to 16, Fig. 2 (a)) two tones (12 and 15) are chosen and printed in high contrast tones (11 and 16) as a tonally separated representation which is scaled for application to a model blank by for example etching using a photoresist or a transfer process. Several separations can be used to etch a single blank to give a range of depths and hence greater detail. The invention overcomes the problem of imparting fine detail to very small scale models particularly for use in flight simulators since optical scaling may be used, allowing surface detail to be specified at large scale. <IMAGE>
