Title: Improvements in or relating to voltage current regulating circuits
Inventor: HEALEY ROBERT JOSEPH
IPC: H02M7/155
Filed: 1968-01-15
Abstract: 1,214,574. Automatic control of current and voltage. WESTERN ELECTRIC CO. Inc. Jan.15, 1968 [Jan.16, 1967], No.2048/68. Heading G3R. In a regulated supply arrangement of the type wherein voltage control is superseded by current control when the output current exceeds a predetermined value, the voltage error-sensing detector is incorporated into the current-responsive control loop at cross-over by allowing the current sensing detector to vary the reference voltage of the voltage sensing detector so that the control signal from the latter then responds to current rather than voltage variations. As shown, a load 3 is supplied from a source 1 by way of a regulating stage 2 controlled by a driving stage 12 which itself receives a control signal from a voltage errorsensing circuit constituted by a potentiometer 11 connected across the load terminals, a comparator transistor 7 and a reference Zener diode 8, the arrangement operating in known manner to maintain the load voltage at a constant value until the load current reaches a predetermined level when a signal derived from a load-current sensing resistor 4 biases a further transistor 5 into conduction. Transistor 5 has its collector connected to the Zener diode 8 which thus operates on a different point on its characteristic Fig.3, (not shown) when transistor 5 conducts, the exact point being determined by the degree of conduction of transistor 5. Thus the reference voltage applied to transistor 7 in the voltage error-sensing circuit is varied when the load current exceeds the predetermined level causing the control signal from transistor 7 to vary in accordance with load current rather than load voltage, whereby the regulating stage 2 is then controlled to maintain the current constant at the predetermined level. The specification states that this arrangement provides a smooth cross-over from constant voltage to constant current regulation. The arrangement may be employed in switching and variable impedance regulators and for either series or shunt regulation. An embodiment employing thyristors in the regulating stage is decribed with reference to Fig.4 (not shown).

Title: Circuit for regulating the level of carrier frequency telegraphy with amplitude modulation
Inventor: POLLAK VIKTOR
IPC: H04L27/08
Filed: 1954-01-26
Abstract: 771,061. Code telegraphy. TESLA, NARODNI PODNIK. Jan. 26, 1954, No. 2344/54. Class 40 (3). In a circuit arrangement for regulating the operating level of signals transmitted as amplitude modulation of a carrier frequency, the output of the secondary winding of a transformer 1 is fed to rectifiers 2, 3 with parallel circuits R1, C1 and R2, C2 to produce voltages fed in opposition to the grid of the valve E, the time constant of the circuit R1, C1 being much shorter, and that of the circuit R2, C2 much longer, than a telegraph impulse period. The voltage fed to the capacitor C2 of the circuit with the longer time constant is arranged to be one half of that fed to the capacitor C1 of the circuit with the shorter time constant. The transformer 1 may be replaced by a voltage source feeding voltages of opposite polarities to the rectifiers 2, 3. In the case of half-wave rectification, as shown, the same half-wave must be rectified by the two rectifiers 2, 3. The incoming signal may be applied to devices providing full-wave rectification. The voltages across capacitors C1, C2 are of opposite polarity and the resultant voltage is applied to the left-hand grid of the valve E, and in inverted form to the right-hand grid of the valve which is operated in push-pull. Windings P1, P2 of the receiving relay are connected in the anode circuits of the valve, and resistors R10, R11 together with an adjustable potentiometer R 12 control additional currents in the windings to provide a desired marking or spacing electrical bias in the operation of the relay. For adjustment and testing purposes the minimum current for the operation of the relay by its winding PI is indicated by an ammeter I in parallel with a resistor R9 in series with the operating windings P1, P2 of the relay.

Title: An improved arrangement for reducing the frequency band in the heterodyne reception of frequency-modulated oscillations
IPC: H03D3/00
Filed: 1946-01-25
Abstract: 620,668. Frequency modulation. PATELHOLD PATENTVERWERTUNGS- & ELEKTRO-HOLDING AKT.-GES. Jan. 25, 1946, No. 2566. Convention date, Jan. 27, 1945. [Classes 40 (v) and 40 (vi)] In a frequency-modulation receiver, the received wave is divided in frequency by a heterodyne mixer, the second input of which is derived from the I.F. output through a limiter, a frequency-multiplier and a band-filter. The incoming wave, or preferably a wave of lower frequency derived therefrom, is fed to a mixer M2, the output of which is amplified at ZF2 and is fed through a limiter B to F.M. detector D. The limiter B also feeds a frequency-doubler or frequency-multiplier V, and the multiplied output is filtered and constitutes the second input to the mixer M2. If the multiplying factor of V is n, the mixer output is at 1/nŒ1 times the input frequency. The output from the multiplier V may be used to synchronize a local oscillator which feeds the mixer M2 (Fig. 3, not shown). As shown, the frequencydividing stage M2, ZF2, B, V follows an ordinary heterodyne stage M1 in which the local oscillator O is of the magnetron type and has its frequency automatically adjusted by the output of the discriminator D fed through a low-pass filter TP. Two or more frequencydividing stages may be arranged in cascade (Fig. 4, not shown). The frequency multiplier V may comprise a multi-vibrator circuit (Fig. 6, not shown). Specifications 554,914 and 556,171 are referred to.

Title: Improvements in or relating to coin-actuated mechanisms
Inventor: STILL FREDERICK WILLIAM

Filed: 1957-01-25
Abstract: 834,921. Coin-freed machines for dispensing liquids. STILL & SONS Ltd., W. M. Jan. 22, 1958 [Jan. 25, 1957], No. 2839/57. Class 27 A coin-actuated apparatus for automatically dispensing a beverage such as tea or coffee in which the choice of an optional ingredient, e.g. sugar, is provided for, comprises two coin-receiving channels 10, 12 each having a coin-actuated switch 14, 16 connected in a circuit for controlling the dispensing of the optional ingredient; the switch 14 is normally open but closes momentarily on the passage of a coin to permit dispensing of the optional ingredient, but the switch 16, normally closed, is momentarily opened by the passage of a coin to open the control circuit and thus to prevent dispensing of the optional ingredient. When the switch 14 is closed by a coin, a solenoid 18 is energized to close two jointly-operated switches 22, 24, the former switch closing a holding circuit between the solenoid 18 and a second source of electrical supply 26 before the switch 14 is reopened by the passage of the coin. The coin in channel 10 then passes to a common channel to close momentarily a switch 28 which connects a further source 36 of electrical supply with a time-controlled motor-switch 29/31. The closing of the switch 31 connects a further source of supply 35 to put in circuit three solenoids 30, 32, 34 which operate valves in the outlets of the containers for tea, milk and sugar syrup respectively. The switch 31 is opened by the motor to de-energize the solenoids 30, 32, 34, and thus to close the valves operated by them, after the dispensing period is completed. While the switch 31 is closed, hot water is also dispensed to a predetermined level, below which a float-operated switch 38 opens the circuit between the solenoid 18 and the source 26, thereby reopening switches 22, 24. To obviate the "accidental" dispensing of the optional ingredient following the insertion of a damaged or otherwise unacceptable coin in channel 10, the switch 14 being closed thereby but the coin being rejected before reaching the switch 28, the channel 12 is provided with the switch 16 which is opened momentarily by the passage of the coin through that channel, thus breaking the holding circuit of the solenoid 18; the unsweetened beverage will be dispensed through the action of the solenoids 30 and 32, which depend only on the closing of the switches 28 and 31 to complete the circuit from the source 36. Specification 796,831 is referred to.
