Title: Improvements in or relating to devices for measuring the height of pulses which occur in a series of pulses
IPC: H01H13/24
Filed: 1959-12-08
Abstract: 931,004. Pulse height measuring. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 8, 1959 [Dec. 11, 1958], No. 41695/59. Class 37. Pulses are applied in the positive sense to one amplifier 3 and in the negative sense to a second similar amplifier 6 over control circuits which clamp the negative peaks of the pulses applied to the grids of both valve 3, 6 to zero. The anode current a, Fig. 2, of valve 3 thus has a waveform similar to the input pulses and the anode current b, Fig. 2, of valve 6 has a complementary waveform. The sum of these currents is fed through a meter 9 which thus gives a smooth reading proportional to the height of the pulses. As shown, the input pulses are applied only to valve 3 which is adjusted to unity gain to feed similar but inverted pulses to valve 6. The input waveform may be sinusoidal in which case the peak-to-peak height is measured. A backing-off voltage source 14, 15 may be used to adjust the meter to zero in the absence of any pulse input.

Abstract: 1,235,245. F.E.T. dividers. SOCIETE SUISSE POUR L'INDUSTRIE HORLOGERE S.A. 25 Aug., 1969 [26 Aug., 1968], No. 42296/69. Heading H3T. [Also in Division G3] An electronic watch comprises a timebase producing high-frequency electrical pulses, an electronic sealer, and a time indicating device controlled by the low-frequency pulses produced by the sealer, the sealer being an integrated circuit consisting of several cascaded stages in which the later stages operating at low frequencies each comprise an amplifier C4, T4 using a field effect transistor with an insulated control electrode. The Figure ahows one of the lowfrequency stages of the sealer which halves the frequency of its input signal S1 Transistors T1-T7 are of MOS field effect type and capacitors C1-C6 are also MOS capacitors. Cp represents the input capacitance of the transistor T4 and to overcome the incorrect operation of the sealer at low frequencies due to the leakage of the charge on the capacitor Cp, each low-frequency stage includes a compensating circuit including the transistors T5-T7 and the capacitors C5, C6. The compensating circuit is supplied by a source S2 which may be the watch timebase, a preceding sealer stage producing a signal of sufficiently high frequency or an independent source. The compensating circuit periodically recharges the capacitor Cp with each pulse from the source S2 to ensure that the capacitor is charged for a sufficient time to enable the sealer to operate correctly. A modified compensating circuit including a direct voltage source is also described.

Abstract: 1,151,881. Protective arrangements. COAL INDUSTRY (PATENTS) Ltd. 21 Oct., 1966 [22 Oct., 1965], No. 44773/65. Heading H2K. Apparatus for scanning a plurality of signal channels T/C 1 , T/C 2  providing signals having different trip levels, for the purpose of measuring the signals and providing a tripping action when a trip level is exceeded, comprises a device 10 connectable to each channel in turn, directly for measuring, and indirectly through a modifying circuit adjustable to modify the signal so that its true trip level is shifted to a nominal value corresponding to the trip setting of the device 10. This device includes a pointer movable along a scale in dependence on the applied voltage and an adjustable trip indicator. When the pointer coincides with the indicator, a relay 16 opens a trip circuit 17. A rotary switch may be stepped round by a coil 15 under the control of a pulse generator 18, or a push-button switch 19. When the switch is in its first position shown, the channel T/C 1  is connected directly to the device 10 which measures the applied signal, e.g. from a thermocouple, and a green lamp 26 is lit. When the switch steps to its next position with contacts 22, 23 closed, a bias voltage from a variable resistor VR 1  connected across a stabilized supply SB is added to the voltage from the channel T/C 1  to cause tripping if the combined voltage is sufficient. In this position of the switch, the lamp 26 is extinguished and a red lamp 27 is lit to indicate that the device 10 is not indicating a true measure of the signal voltage. Should tripping occur a relay RL1 opens its contacts RL1b so that the stepping action of the switch ceases, the lamp 27 indicating the channel causing the tripping action.
