Title: Liquid metering method and device
IPC: G01F1/68
Filed: 1978-10-31
Abstract: A device for automatically metering liquid includes a container 10 for holding liquid F to be metered and having a liquid discharge control valve 12. The upper end of the container is closed by a cover 15 having an inlet pipe 21 for pressure compensation, in which inlet pipe there is a nozzle-like opening 20 of a given cross-section in whose flow range an NTC resistor system 30 of an anemometer circuit. The output of the anemometer circuit is a voltage proportional to the airflow rate through the inlet pipe 21, the voltage being fed to an input of an analog voltage/frequency converter 50 which supplies an a.c. voltage (or a pulse train) at a frequency proportional to said voltage. The frequency of the output of the converter is compared with a preset comparison count value in a counter 60. The count value counted by the counter 60 is proportional to the volume of air which has flowed into the container during pressure compensation, and an output of the counter is fed to a circuit 80 controlling the discharge valve 12 in the liquid discharge pipe 11. <IMAGE>

Title: Measuring capacitance
IPC: G01F23/26
Filed: 1978-11-30
Abstract: A capacitance-to-frequency conversion circuit includes two feedback circuits (7 and 8) supplied with an alternating signal from an oscillator (1). The first feedback circuit (7) includes a capacitor (12) and provides an output signal dependent on the frequency of the alternating signal to one input of a comparator (9). The other feedback circuit (8) includes a diode pump circuit and provides an output signal independent of frequency to the other input of the comparator (9). The output signal of the comparator (9) varies in accordance with the difference between its two input signals, and is supplied to the oscillator (1) to control its frequency such as to reduce the difference between the two comparator input signals. The capacitor (12) may be included in a capacitive probe (10) for measuring fluid-level in a container. <IMAGE>

Patent GB-2034993-A (GB)
Title: Method for high resolution and high accuracy time measurement
IPC: G04F10/00
Filed: 1979-09-25
Abstract: A time duration is measured precisely and with high resolution by making three time measurements as shown in FIG. 5. The time difference tA between the leading edge of a start signal and the next following leading edge of a constant frequency time base signal is measured. The number "n" of the following leading edges is then counted including the leading edge of the time base signal following a stop signal. The number n is multiplied by the period TQ of the time signal. The time difference tE between the leading edge of the stop signal and the next following leading edge of the time base signal is measured. The real time difference  DELTA t is then calculated as follows  DELTA t=tA+nxTQ-tE. A three part real time measurement is performed to correct the calculated result for drift and aging. Calibration measurements are made and the respective calibration factors are used in calculating the final results. The respective circuit arrangement includes a start channel, a stop channel, and the corresponding supporting circuits.

Patent GB-2056123-A (GB)
Title: Injection-timing regulator for a fuel injection pump
IPC: F02M41/12
Filed: 1980-07-28
Abstract: An injection-timing regulator in fuel injection pump has a timing piston subjected to the fuel pressure in the pump suction chamber 5, which pressure is controlled in dependence upon engine speed. An optimum instant of injection is obtained by further controlling the fuel pressure in the chamber 5 in dependence upon operating conditions of the engine by means of a solenoid adjustable relief valve 28. At low load, the speed- dependent pressure in the suction chamber 5 is relieved via a first bore 44 and via a second bore 47. At high load, the coil 33 is energised to change over the valve member 35 and so close the second bore 47 and increase the resistance to the relief fuel flow. This increases the pressure in the suction chamber 5 and so advances the instant of onset of injection. There is a continuous fuel flow through a bore 52 in the closure member 35 to an annular groove 51 and this wipes the bore 36 of the valve housing 30 clean. <IMAGE>

Title: Electric switch
IPC: H01H13/54
Filed: 1980-09-19
Abstract: An electric switch for incorporation in a telephone to provide a short timed break in the line to be detected by the exchange as a signal includes first and second contacts (1, 2) and manually operable actuating means (3, 4, 5, 6, 8) operative to cause the contacts (1, 2) to open. The manually operative actuating means includes a spring- mass system (4, 5) such as a spring biased balance wheel 4 which is rotated by a spring 11 when an operating button 8 is operated. Movement of a pin, magnet or (as shown) a ramp (3) on the wheel 4 causes the contacts (1, 2) to open and upon completion of one oscillation the contacts (1, 2) are reclosed. The period of oscillation is substantially independent of the manner of manual operation of the actuating means (8). The contacts (1, 2) may be held open by the cradle of the telephone when the telephone is not in use.   <IMAGE>
