Patent GB-1138606-A (GB)
Abstract: 1,138,606. Taximeters. GEECEN Ltd. 10 Feb., 1966 [25 Feb., 1965], No. 8137/65. Heading G4T. A taximeter having control devices driven in accordance with time and/or distance to advance a fare indicator firstly in accordance with a first tariff and then in accordance with a second tariff, is provided with further mechanism which subsequently produces a third tariff. A shaft 16 is driven by two unidirectional clutches, as described in Specification 971,014, one from a clockwork mechanism and the other by the movement of the vehicle which is transmitted via gear-wheels 142, 144, 145, 162 and further gears not shown. Pinions 144, 145 are mounted on levers 146, 147 and are controlled to change the gear ratio by cams 156 driven by the usual electric motor of the taximeter. When the taximeter is set to " HIRED " a pawl 48, mounted eccentrically on the shaft 16, cooperates with ratchet teeth 47A to advance a disc 126. During this period a tooth 12A rides on the periphery of the disc 126, preventing fare advance movements of a ratchet 10 by a pawl 11 as lever 12 is oscillated by a two-lobe cam 15. When, however, a slot in the periphery of disc 126 comes opposite tooth 12A, alternate movements of the lever 12 cause fare advance movements of ratchet 10 by pawl 11. This constitutes the first tariff period and during it a further ratchet wheel 171 is driven against a spring 174 by a pawl lever 172 operated by a cam 173 on the shaft 16. After a predetermined angular movement of ratchet wheel 171 the lower end of a pawl 168 moves into a recess 170 thus allowing the upper end of the pawl to engage and hold the teeth of disc 126 in a position such that tooth 12A on lever 12 moves into the slot during every oscillation of the latter, thus doubling the frequency of the fare advance movements. This constitutes the second tariff period and the advance of a ratchet wheel 171A mounted on the same shaft as ratchet wheel 171 (see Fig. 2) eventually brings a recess 170A opposite the lower end of a further pawl 168A, the consequent movement of which causes closure of contacts in the circuit of the taximeter motor which, by rotating camshaft 158 causes operation of the change-gear mechanism 146, 147, 144, 145 &c. to provide the third tariff.

Abstract: 1,229,026. Accumulator circuits. INTERNATIONAL BUSINESS MACHINES CORP. 4 Sept., 1968 [15 Sept., 1967], No. 41948/68. Heading G4A. An accumulator circuit receives from memory plural-digit quantities coded so that some possible digit combinations are excluded from the code, passing each quantity to a register via an arithmetic logic circuit operable to perform an arithmetic operation on the quantity in accordance with the register contents, the result of each operation being stored in the register, then passed to the memory via the logic circuit with concurrent correction using a generated correction factor if the result was a combination excluded from the code. Addition.-Two binary-coded-decimal digits to be added are passed in turn serially-by-bit (low order first) from memory (at SA, Fig. 5e) via a trigger S (Fig. 5e) and add-subtract logic (Fig. 4, top left) into a trigger P8 of a shift register P8, P4, P2, P1. The logic also responds to trigger P1 of the register and a carry trigger CY. The register is shifted as each bit is entered. In this way each bit of the first digit is entered into the register (and rewritten in memory via terminal 52) then the second digit is added to the first by the logic. In this and other logic shown, horizontal inputs to a vertical line are ANDed at the line and vertical lines joining a horizontal line are ORed at the horizontal line. The carry trigger CY is also set as appropriate by logic shown. If the result is over 9, logic in Fig. 5b responds to the register to produce a "not BCD" signal which sets an "add 6" latch (Fig. 5c, this being a latch due to the feedback from 22 to 22a). The register is shifted out so the result is written into memory via the addsubtract logic (Fig. 4, top left), and terminal 52. If the "add 6" latch is set, trigger S is set during the "2" and "4" bit times to add 6 to the result at this logic, and the carry trigger CY is set to await the next decimal order. Subtraction is similar to addition except that entry of the first digit into the register is preceded by setting the register to a value of ten by the "not set 10" inputs shown, and the "sub" control signal is on as the first digit is being entered and during "8" bit time of writing the result in memory. Multiplication or division by ten is done by using the shift register P8, P4, P2, P1 as a onedecimal-digit delay between reading from and rewriting into memory of successive BCD digits taken low or high decimal order first for multiplication and division respectively. Modifications.-Alternative memory read and write sequences for obtaining the two operand digits and rewriting the first are described.

Abstract: 1,231,910. Switching systems. WESTING- HOUSE ELECTRIC CORP. 27 May, 1969 [7 June, 1968], No. 26742/69. Heading H2H. A circuit arrangement for generating an auxiliary D.C. supply from an apparatus comprising a full-wave rectifier having a controlled rectifier connected across its output terminals includes timing means whereby the D.C. supply is maintained at times when the controlled rectifier is conductive. A D.C. supply is generated on leads 41, 42 by means of a full-wave rectifier bridge 31-34 fed from an A.C. supply 35, 36. The output terminals of the bridge are interconnected by a thyristor 43 the gate terminal of which is connected to the connection between a Zener diode 52 and a transistor 55, the D.C. supply being used to supply a load, generically indicated by a resistor 50, and also to charge a capacitor 49. Initially, on switching on, the thyristor 43 is non-conductive and the capacitor 49 charges up from the output of the bridge by way of a resistor 45 and a diode 47. When a sufficient charge is present on the capacitor the Zener diode conducts to trigger the thyristor 43 should a requisite control signal be present on the base 58 of the transistor 55. When the thyristor is conductive the output of the bridge disappears, the D.C. output then being maintained by the capacitor 49. The signal to the base of transistor 55 may be obtained from a timing circuit which includes a capacitor and a variable resistor together with a transistor. This capacitor is initially charged from the output of the rectifier bridge to a voltage determined by the variable resistor during which time the thyristor is non-conductive. When it is required to make the thyristor conductive the capacitor is connected to the A.C. supply by way of a diode to increase the charge thereon, the thyristor being rendered conductive when this charge has reached a predetermined value.

In a modification of the oscillator of the parent Specification, a control voltage converter 21 is included between control unit 13 producing the control quantity and the varactor element 8 so that the output of the converter 21, in response to a linear input variation, varies in a non- linear manner substantially the inverse or opposite of the tendency of the frequency/ voltage variation such that the tendency of the frequency/voltage variation to depend non- linearly on the control voltage is reduced. The voltage converter 21 may include variable resistors 23, 24 and a voltage dependent resistor 25 and compensates for non-linearities introduced due to the characteristics of the varactor 8. This converter 21 replaces the non-linear adjuster 15 of the parent Specification which is now used to compensate for non-linearity introduced by the sensing device 12 such as a transistor or thermistor. The adjuster 15 converts a linear input into a non-linear output to provide correction for non-linear dF/dT frequency/temperature variation. The frequency of the Gunn effect oscillator 4 is adjustable by electronic frequency set circuit 16 which adjusts the varactor tuning voltage. A sensitivity compensator 27 coupled to the frequency set 16 provides control of the control and compensator 13. As in the parent Specification the temperature compensation of the Gunn effect local oscillator may be matched to that of a magnetron transmitter in a radar device.
