Title: Automatic multirange digital data display apparatus and control therefor
IPC: G09G3/04
Filed: 1970-02-12
Abstract: 1286007 Digital data displays HEWLETT-PACKARD. CO 12 Feb 1970 [17 Feb 1969] 6890/70 Heading G4H Apparatus for displaying digital data in the form of a mantissa and an exponent comprises a circuit 65 which examines the most significant digit of the existing numerical display, a circuit 61 which examines the most significant digit of the number to be displayed and a circuit 73 which may provide an inhibit signal to a circuit 30 to prevent the exponent value being changed when the number is displayed. Data is fed to a processing unit 9 such as a counter, a computer, &c. which includes a shift register 11-19 and a decimal point 25. A display signal from a control circuit 21 enables the circuit 30 to provide a control signal to a logic circuit 49 which causes the transfer of the mantissa data from the processor 9 to buffer stages 31-39 and the transfer of the computed exponent value to a display 50 via the circuit 30. The mantissa of the numerical data is displayed in apparatus 51-59 provided with decimal point indicators 43-47 whilst the exponent display 50 comprises a number such as 10<SP>3</SP>, 10<SP>6</SP> or the equivalent word kilo, mega. If the most significant digit of the previously displayed number was a "0" or a "1", and the most significant digit of the number to be displayed is a "9", the circuits 61, 65 supply signals to the circuit 73 which in turn provides the circuit 30 with an inhibit signal to prevent the exponent display 50 from being changed. Thus small fluctuations of the displayed number above and below the exponent value do not cause repeated changes of the displayed exponent.

Abstract: 1,172,353. Transistor switching circuits. PYRENE CO. Ltd. 16 Feb., 1967 [16 Feb., 1966], No. 6900/66. Heading H3T. [Also in Divisions G1 and G4] A smoke detector circuit, Fig. 1, is provided with a thermistor T for temperature compensation and includes the lamp L1 and the photocell, a photo-resistor RV, whose output may be amplified (by transistor TR1) before being applied to the triggering electrode of a thyristor, e.g. silicon controlled rectifier SCR1. Voltage stabilization is provided by transistor TR2 together with resistor R4 and Zener diode Z2, and protection of the thyristor against transients by capacitors C1, C2. When an increase of light on photo-cell RV is sufficient such that the voltage across R2 reaches the sum of the voltage set by Zener. diode Z1 plus the firing voltage of the SCR, the latter is switched on and current flows in signal line 5 to light lamp L2 and energize device 6. The signal current may, in an alternative arrangement, be added to the line current or be detected by a transformer having a further thyristor in its secondary circuit which is fired in the event of smoke detection. A lamp failure, indicated by a decrease in line current, may also be indicated using this arrangement. A number of smoke detectors may share the same alarm system when this arrangement is used. Specification 1,172,354, which claims the feature of using a thermistor in series with the light source, is referred to.

Abstract: 1498121 Automatic control of speed MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 19 Feb 1975 [8 March 1974] 6907/75 Heading G3R A speed regulating system for a rotary machine controlled by a D.C. supply voltage, includes a speed detector providing a time varying signal, dependent upon machine speed, which is combined with a reference timing signal. The combination is smoothed and compared with a reference D.C. voltage which varies with the voltage of the D.C. supply, the result being used to control the rotary machine so as to regulate its speed to a predetermined value, independently of variations in the D.C. supply voltage. As shown, a tachometer 11 provides an output signal whose frequency depends upon the speed of D.C. motor 10. Differentiating and waveform conversion circuits 12, 13 are used to derive, from the tachometer signal, a rectangular waveform whose frequency is dependent upon motor speed and whose amplitude varies with the motor D.C. supply. This rectangular waveform is smoothed by an integrating circuit 14 and compared at 16 with the reference D.C. voltage that is derived from a voltage divider across the motor supply. The result is used to control the voltage across the motor, so as to regulate the motor speed. Waveform converter 13 may include a hook switch and pulse generator, a sawtooth generator and comparator or a phase comparator. Details of the circuits are given in other Figures (not shown).
