Patent GB-2043402-A (GB)
Title: Improvements in or relating to methods of, and apparatus for, demodulating frequency-division multiplex (FDM) signals
IPC: H04J4/00
Filed: 1979-11-15
Abstract: A method of, and apparatus for, demodulating FDM signals in which the input FDM signal is time compressed followed by conversion into time-division multiplex (TDM) format enabling high speed serial demodulation to be effected. Time-compression is achieved by means of a buffer store 2 into which samples of the input signal are written at a first rate R1 and then cyclically read out at a second faster rate R2. The contents read from the buffer store during each reading cycle occupy a separate time slot of the TDM signal which has a number of channels corresponding to the number of sub-channels of the FDM signal from which information is to be derived. The time-division multiplexing of the time-compressed FDM signal involves down-conversion of the respective sub-channels to a common carrier frequency, after which the TDM signal can be serially demodulated by a common demodulation unit 7. The output of the demodulation unit is then de-multiplexed at 8 to produce a plurality of parallel output signals each containing data from a respective sub-channel of the original FDM signal. The technique obviates the need for separate frequency selection and demodulation circuits for each channel resulting in a substantial economy of hardware. The apparatus described can be programmed by appropriate selection of certain parameters to deal with a variety of signal formats having different numbers of channels, baud rates, carrier frequency spacings or bandwidths. <IMAGE>

Title: A method of presenting coins in an orderly sequence and apparatus for carrying out that method
IPC: G07D5/02
Filed: 1980-07-11
Abstract: Coins are dropped through a hole in the top cover 12 and fall onto non-central parts of a disc 25 rotated by a motor 29. The coins spread out and are carried round to an opening 30 in a wall 23 surrounding the disc. They are thrown centrifugally through the opening, tip up and roll down a track 15 encircling a cylindrical support 13. The coins lean against an outwardly inclined barrier 16 or against one another. Those coins leaning against the barrier travel more slowly than those leaning against other coins so that the coins become separated, and leave the track in an orderly sequence. Near the bottom of the track the coins pass an array 37 of photosensitive diodes and temporarily occlude some of them. The resultant signals is used to determine the diameter or width and thus the denomination of each coin and the total value of the coins. <IMAGE>

Title: Sonar intruder detectors
Inventor: SOTHCOTT PETER
IPC: G01S15/04
Filed: 1981-10-20
Abstract: A sonar intruder detector for protecting a harbour mouth, river entrance or coastline which has a string of fixed beam sonar transducers (1) arranged along the line to be protected. These transducers each project a pulse-modulated sonic beam up towards the surface, and are sequentially triggered by a pulse on a cable interconnecting them. Any object (2) which crosses the sonar "fence" thus provided reflects the sonic pulse and this for reflection is detected and processed as in radar to give an indication that the "fence" has been crossed and where. To indicate whether the object is entering or leaving two such fences parallel to each other are used. The transducers may operate at different frequencies. <IMAGE>
