Patent GB-1334059-A (GB)
Title: Electronic processing apparatus
IPC: H04H20/88
Filed: 1970-12-18
Abstract: 1334059 Monitoring pulse trains; radio signalling RCA CORPORATION 18 Dec 1970 [29 Dec 1969] 60159/70 Headings H3A and H4L A circuit monitoring a train of random pulses comprises a bi-stable set to one state by the random pulses and set to the other state by regularly recurring pulses of longer duration, the output of the bi-stable being fed to an average detector. Composite stereo signals from a tuner 12, and a 114 kHz signal from source 18 are fed to a noise detector 16 which translates noise of the composite signal, lying in the region of 114 kHz, down to a low frequency band which is fed via adjustable low pass filter 40, 42, 44 to a threshold circuit 46, 48, 50. If the amplitude of this signal exceeds that of threshold source 52, it is passed to the set input of a bistable 66, 68, which receives as its reset input, a signal from source 84. As long as noise signals are present at the bi-stable set input, the bistable will switch to produce a pulse output signal which allows capacitor 64 to discharge and operate switch 62. The output from the noise detector automatically adjusts itself to allow more noise in loud music passages before switching occurs.

Title: Method of and apparatus for modulated sample feed in the spectrochemical analysis of solution
IPC: G01N21/71
Filed: 1969-12-15
Abstract: 1,268,530. Sample feeder. CARL-ZEISSSTIFTUNG [trading as CARL ZEISS]. 15 Dec., 1969 [20 Dec., 1968], No. 60992/69. Heading B1X. [Also in Division G2] In the spectrochemical analysis of a solution, a vaporiser-burner combination 1 is fed with a modulated sample of the solution 6. The solution passes from a vessel 5 through a capillary tube 4, a flexible capillary hose 3 and capillary tube 2 to the vaporiser 1. A member 7 slidably supported at 9 is connected to a rod 10 pivotally secured to a drive disc 11 which rotates to produce a reciprocating motion in the direction of arrow 12. This causes the formation within tube 4 of individual liquid columns separated by columns of air. Vessel 5 can be adjusted to allow for the drop in liquid level. The end of tube 4 can be made to remain in the solution 6 during a reciprocating cycle or be lifted above the liquid level. In a second embodiment, Fig. 2 (not shown), three solutions in a divided vessel (14) are successively fed to the vaporiser 1 through the tube 4 which is simultaneously rotated and lifted by a rod (18) and disc (19) driven by a motor (22). In a third embodiment, Fig. 4 (not shown), two solutions (43), (44) are alternately fed through respective flexible tubes (37), (38) to the vaporiser 1. In a fourth embodiment, Fig. 3 (not shown), the solution is fed under pressure by a piston (26) through a tube (23) which is reciprocated.

Patent GB-614288-A (GB)
Abstract: 614,288. Counting-apparatus; rate recorders. C. A. V., Ltd., and BEVIS, W. A. July 11, 1946, No. 20720. [Classes 106 (i) and 106 (iii)] Apparatus for determining the total amounts of time spent by a rotating shaft in certain predetermined speed ranges comprises an electromagnetically-operated counter for each range, means for supplying current impulses at a known rate and a relay associated with each range which operates to connect the impulsesupplying means to the appropriate counter when the corresponding rate of rotation is reached. It is described with reference to a motor vehicle, which, as shown, drives a voltage generator 1 so that the voltage is proportional to the speed, the voltage being applied via normally closed contacts 7b-7i across relay coils 5a-5i. When a certain voltage is reached the coil 5a closes contacts 6a, so that impulses from a battery are supplied to the electromagnetic counter 2a via timing contacts 4 operated by a motor 3 driven from the same battery. When the next voltage range is reached, coil 5b closes the contacts 6b, thus operating the counter 2b and also opens the contacts 7b, thus de-energizing the coil 5a, and similarly throughout the various ranges. In operation, the switches 12 and 13 are closed. To re-set a counter its switch 14 is closed, thus shorting its contacts 6, and a switch 16 is moved to disconnect the contacts 4 from the battery and connect instead a pair of higher speed contacts 9 which thus brings the counter rapidly to zero. In a modification (Fig. 2, not shown), the voltage generator is dispensed with and the battery is selectively connected to the relays by a centrifugal switch.

Title: Automatic excitation control system for synchronous dynamo-electric  machines
IPC: H02P25/02
Filed: 1970-12-31
Abstract: 1359130 Motor control system BRUSH ELECTRICAL ENG CO Ltd 30 March 1972 [31 Dec 1970] 61957/70 Heading H2J [Also in Division G3] An automatic excitation control for a synchronous dynamo-electric machine, i.e. motor or generator, includes means to boost the excitation for a period of less than one minute following a transient reduction in the line voltage to or from the machine. In an embodiment, and under steady state conditions, boost control circuit 11 is off, the excitation of synchronous motor 6 being controlled by power amplifier 5 by the difference between an actual supply signal B from detector 2 measuring, e.g., reactive power or current of three-phase supply 7, and a reference signal A from a Zener diode Zl fed from supply 7 via transformer T 1  and rectifier bridge D 8 -D 13 . A stabilizing signal D is obtained from rate circuit 15. Transient falls in the supply voltage are reflected through transformer T1, rectifier bridge D1-D6, smoothing circuit R1, R2, C1 and capacitor C2, to turn on transistors VT1, VT2, thus providing a boost signal C to amplifier 5, to increase the motor excitation and maintain synchronous operation. Diode D7 across the base of transistor VT1 ensures that transient rises in the supply do not cause a decrease in motor excitation. Resistors R1, R2 in the smoothing circuit set the sensitivity of boost control 11, whose supply, obtained from Zener diode Z2 in series with Zener Z1, sets the maximum for boost signal C, which is reduced to zero after a preset time as capacitor C2 discharges via resistor R3, or if the supply voltage increases rapidly.
Patent GB-1285177-A (GB)
Title: Apparatus for operating a ram
Inventor: HAWES DAVID JOHN
IPC: F02K1/15
Filed: 1968-12-31
Abstract: 1285177 Jet propulsion engines ROLLSROYCE Ltd 16 Dec 1969 [31 Dec 1968] 61973/68 Heading F1J A ram piston 2 is supplied on one side 7 with fluid at an operating pressure P R  which is controlled by means including at least one vortex amplifier for causing the pressure P R  to vary in accordance with any departure of a given pressure or pressure ratio from a predetermined magnitude. The ram actuates a variable-area jet nozzle of a gas turbine engine, either directly or via a hydraulic servo-mechanism. A pneumatic pressure P 3  derived from the discharge pressure of the H.P. compressor of the engine is applied to the other side 8 of the piston 2 and is also applied to the jet nozzle 16 of a confined jet amplifier 15 and to a swirl-including nozzle 26 of a vortex amplifier 20 which is connected series with the amplifier 15 and exhausts at 23 to ambient or low pressure P o . A reference pressure P x,  derived via a potentiometer 35, 36 from the pressure P 3  and a pressure P 2  which is derived from the discharge pressure of the L.P. compressor of the engine, is applied to another swirl-inducing nozzle 25 of the vortex amplifier 20. If the fuelflow to the engine reheat burners is increased, the resultant rise in the jet pipe pressure P 6 , which pressure (or a pressure functionally related to it) is applied to a further swirl-inducing nozzle 24 of the vortex amplifier 20, increases the pressure drop across the vortex amplifier and therefore increases the pressure within the confined jet amplifier 15. This increases the pressure P R , which is obtained from the receiver 14 of the confined jet amplifier 15. Consequently the piston 2 is moved to the left by the pressure P R  to open the variable-area nozzle. The increase in the pressure P R , which pressure (or a pressure functionally related to it) is applied to a swirlinducing nozzle 50 of a vortex amplifier 42 in opposition to the pressure P 3  which is applied to an opposing swirl-inducing nozzle 51, increases the pressure drop across the amplifier 42, which exhausts to the pressure P o  via a restrictor 46, to cause the pressure P x  at its inlet jet nozzle 43 to increase. This increase, communicated to the swirl-inducing nozzle 25 of the amplifier 20, causes the pressure drop across the amplifier 20 to fall until the pressure P x  becomes equal to the pressure P 6 . This fall in the pressure drop produces a fall in the pressure P R  so as to prevent further leftward movement of the piston 2, thus providing negative feedback. The degree of negative feedback may be varied by altering the direction of swirl induced by the nozzle 50, in order to speed up the opening and closing of the variable-area jet nozzle.
