Patent GB-2033091-A (GB)
Title: Fluid gauging method and system
IPC: G01F23/26
Filed: 1979-09-28
Abstract: A method and system for indicating the mass of fuel in several tanks (2, 3,4) each having a capacitive depth sensor (8, 9, 10) and a permittivity cell (21, 22, 23). The sensors and cells supply signals to a computing unit (20) which computes the volume and approximate density of fuel in each tank. A densitometer (33) and another permittivity cell (31) receive a sample of all fuel supplied to the tanks. The computing unit derives a correction factor for each batch of fuel by comparing an approximate value of density derived from the other permittivity cell (31) with a more accurate measure of density derived from the densitometer. A combined correction factor is calculated for the mixture in each tank, from the volume and respective correction factors of the constituent fuels and this is used to correct the approximate values of density derived from the permittivity cell in each tank. <IMAGE>

Patent GB-2042379-A (GB)
Title: Method of producing semifinished nickel products
IPC: B21C37/04
Filed: 1980-02-13
Abstract: To reduce the cost of producing nickel strips, wires and other elongated forms of semifinished nickel products from electrolytically deposited nickel cathode plates and, at the same time, improve the purity of the products, the plates are converted directly into bars, which may be drawn and/or rolled, without a melting operation, by cutting and welding the plates. The plates may first be rolled to reduce their thickness. The plates may be cut into strips which are butt-welded end to end or the plates may be welded together to form wide strips which are then cut lengthwise to form the bars. Welding may be by nickel electrodes of high purity the electrodes being semifinished by the method of the invention.
Patent GB-2046482-A (GB)
Title: Electronic timepiece
IPC: G04C3/14
Filed: 1980-03-28
Abstract: In an electronic timepiece wherein a stepping motor 1 (Figure 1) drives a time display, time resetting by wholly mechanical means requires blocking of the rotation of the stepping motor 1, and blocking of the mechanical type is avoided by the invention. A STOP switch 10 actuated by a time resetting stem sets to state "1" a flip-flop 11 which blocks gates 12 and 13 for controlling the passage of the pulses which drive the motor 1 through a feed circuit 2. The circuit 2 then passes a continuous current in the same direction as the last drive pulse. The continuous current holds the motor rotor stationary and leaves the position of the rotor unchanged. A counter 14 counts 1- second pulses and then resets the flip- flop 11, which automatically causes the motor to resume normal operation after a predetermined period eg 60 seconds. This avoids excessive discharging of the battery of the watch if the user forgets to return the stem after a time resetting operation. <IMAGE>
