Patent GB-2037990-A (GB)
Title: Fluid sensing
IPC: G01F23/24
Filed: 1979-12-20
Abstract: To compensate for variations in ambient temperature a system for giving a warning indication when liquid in a reservoir (2) reaches a predetermined level includes two reversed-biased zener diodes (D1 and D2) mounted at that level and having their anodes connected together. The cathodes of the diodes are connected to respective current sources (30 and 31), the current supplied to one diode (D1) being substantially more than that supplied to the other diode (D2) so that the one diode is thereby heated more than the other diode. When the liquid falls below the level of the diodes, heat dissipation becomes less thereby causing the difference between the temperatures and voltages across the two diodes to increase. <IMAGE>

Title: Watch-dog timer circuit
Inventor: TAYLOR ANDREW EDWIN
IPC: G06F11/00
Filed: 1982-09-07
Abstract: A watch-dog timer monitor for the control system of a power plant including a pulse monitor which measures the length of time between successive control pulses from an output port of a computer. In the event that any control pulses exceeds the preselected time interval, the pulse monitor sends a disable signal through a latch to the buffers in the path of the control signals. The buffers instantaneously transition to a blocked condition preventing any subsequent control pulses from reaching the control system of the power plant. A reset button is toggled to reset an initializer which restarts the program in the computer. A start-up delay is also provided to insure that no spurious control pulses reach the control system of the power plant during a warm-up period when the digital logic circuits are settling out.
