Patent GB-2138137-A (GB)
Title: Improvements in sensing apparatus
Inventor: MEDLOCK REGINALD STUART
IPC: G01D5/243
Filed: 1984-03-07
Abstract: To sense a physical parameter a vibratory element (3) is arranged that its natural frequency of vibration varies with the magnitude of the sensed parameter. The element may be a wire or the like elongate element which is subjected to a tensile or transverse force representing the parameter or a diaphragm which is subjected to a transverse force or a piezoelectric material. In the case of an elongate element, vibration may be in a transverse or torsional mode. The frequency of vibration is sensed by transmitting radiation (1) from a control station (CS) to the vibratory element via an optical fibre (2) and arranging the element (3) so that the radiation is modulated thereby. Modulated radiation is returned via an optical fibre (4) to the control station and the frequency of modulation is sensed. For effecting vibration of an elongate element the element may be disposed in a magnetic field (B) and an alternating driving signal applied to the element. The driving signal is generated by a photodiode (9) activated by radiation transmitted from the control-station via an optical fibre (8). For effecting vibration of a diaphragm, an alternating driving signal is applied to an associated electromagnet. The invention is particularly suited to use in hazardous environments. <IMAGE>

Title: Digital communication circuit
Inventor: ODHAMS DAVID CRAWFORD
IPC: H04L7/033
Filed: 1985-09-19
Abstract: A digital circuit which forms the main element of a line interface, between an exchange and the line or between the line and a subscriber's terminal is modular in structure. The intelligence being conveyed includes speech in digital form. One of the modules includes error-checking, based on the line code used, in which binary 1 is sent as 1-0 and binary 0 as 0-1. Hence 00 and 11 are incorrect. The checking involves counting the incorrect and correct codes as received, an incorrect code usually occurring as a result of a spurious phase-shift. If two incorrect codes occur before or at the same time as up to 16 correct ones, an error is assumed and the data extraction stopped. In addition the clock phase is inverted, which if the error is due to phase shift usually cures the thing. If 16 correct codes occur before 2 wrong ones, correct operation is assumed and data extraction continued. Note that in some cases the number of correct and incorrect codes would differ from those just mentioned. <IMAGE>

Patent GB-2166536-A (GB)
Title: Plate freezers
Inventor: DEBENHAM DAVID GEORGE
IPC: F25D31/00
Filed: 1985-10-23
Abstract: The invention relates to a method for operating a plate freezer comprising a stack (1) of pairs of freezing plates (2) each defining between them a freezing zone (A,B,C,D,E,F) in which method the freezing zones are successively brought into register with a feed station (7) from which articles are fed to the freezing zones to fill the zones in a spaced sequence so as to leave one or more empty zones between the filled zones on the rising stroke of the freezer. These empty zones are then filled on the fall stroke of the freezer so that at the end of the filling cycle the last zone to be filled is adjacent the first zone to be filled. Discharge of the freezer can be carried out by raising or lowering of the zones through only one zone to bring that first zone into register with the feed/discharge station (7, 8). The invention also provides a plate freezer in which the stack of plates is moved by means of a screw actuated mechanism (10), notably by means of screw jacks located at or adjacent each corner of the stack of plates. <IMAGE>
