Title: Automatic validity checking and type identification of banknotes - uses light diodes and photosensitive detectors to identify characteristic transparency patterns in tracks across the notes
Inventor: IGUCHI MASAYUKI
IPC: G07D7/00
Filed: 1976-05-13
Abstract: The network for automatically checking the validity of and also of identifying the value of banknotes uses a set of LED's and photo-sensitive detectors arranged in an array across the path of the banknote, and an evaluation circuit which identifies characteristic patterns of transparency in tracks across the bank note. The number, typically three, of light diode and photosensitive detector pairs (d,d2) are arranged across the path of a banknote (204) moving between two guides (202). An additional pair of diode and detector pairs (1D, 1E) detects the front edge of the banknote and controls the timing the evaluation network (441) to which the amplified gated and time integrated photosensitive detector signals (PA, PB, PC) are fed. The output of the evaluation network is used together with other signal derived from magnetic (JA, JB, JC) dimension and colour disdriminator networks to feed the final evaluation network (442) which generates outputs corresponding to the various banknote type appropriate to the equipment.

Title: Monitor system for unmanned radio stations - uses LF out of band signal to avoid disturbing speech channel
Inventor: BERNI ALBERTO DIPL ING
IPC: H04B1/74
Filed: 1978-05-05
Abstract: The station monitor is designed to supervise the operation of an unmanned radio station and to transmit an alarm signal to a manned station in the system. The intermediate station comprises a working receiver (RCe) and working transmitter (TRe) together with a monitor unit (UC). The latter monitors the operation of both receivers and produces an out-of-band sinusoidal control signal of approx. 80 Hz, for example. This frequency is outside the normal speech band of 300-3400 Hz and therefore does not disturb this channel. If one of the receivers breaks down, the control signal no longer appears at its output (b, c) and the control unit energises an alarm. At the same time it operates a changeover switch (C) to bring into circuit the standby receiver. An alarm signal is transmitted to the manned station which is fitted with a receiver sensitive to the out-of-band signal.

Title: Structural arch support erection - using lifting of central portion with ends resting on ground to be anchored so that support assumes parabolic shape
Inventor: WYCHE CYRIL THOMAS
IPC: E04B1/32
Filed: 1978-11-27
Abstract: A free span arch structure includes transversely spaced elongated flexible sections flexed from a straight configuration without exceeding a yield point to impart a permanent set. Structural sections are lifted by exerting force as by a crane intermediate the ends in a medial portion. An intermediate portion of the pipe is raised by the application of the lifting force while supporting the opposed ends of the pipe on the ground. When the pipe is lifted, the ends restrained and the lifting force removed with the pipe-in a natural state of repose after the application of the load imposed by its own weight, the flexed pipe will assume a parabolic configuration.
