Title: Ignition Warning Lamp Circuits for use in Road Vehicles
Inventor: WILLIAMS MALCOLM
IPC: H02J7/14
Filed: 1966-08-15
Abstract: 1,192,921. Motor vehicle ignition circuits. JOSEPH LUCAS (INDUSTRIES) Ltd. 14 Aug., 1967 [15 Aug., 1966], No. 36413/66. Heading H2H. An ignition warning lamp circuit for a road vehicle includes an ignition switch 13 through which, in use, the warning lamp 27 is illuminated when the generator 15, which may be an alternator with associated full wave rectifier, is not charging the battery 12 of the vehicle; a capacitor, which is charged by the generator, and an amplifier having a high input impedance connected between the capacitor and the ignition switch so as to extinguish the warning lamp when the generator is producing an output. An output from the generator 15 is connected to the +ve side of battery 12 and to the anode of a diode 16, the cathode of which is connected to the capacitor 19 and to the base of a N-P-N transistor 17. The anode is also connected through a resistor 18 to an earthed return line 14. The emitter of transistor 17 is connected to the base of an N-P-N transistor 21, the collectors of transistors 17 and 21 being connected through a resistor 25 to a supply line 11. The emitter of transistor 21 is connected through a resistor 22 to the base of a transistor 23 which has its emitter connected to line 14 and its collector connected to line 11 through a resistor 26 and to the base of an N-P-N transistor 25 whose collector is connected to a warning lamp 27 and whose emitter is connected to the line 14. When the ignition circuit is closed, current flows through resistor 26 and the base emitter path of transistor 25 so that lamp 27 is illuminated. As soon as the generator 15 produces an output the capacitor 19 is charged and the voltage across capacitor 19 is amplified by the Darlington circuit constituted by the transistors 17, 21 which acts upon transistor 23 so that the base current is diverted from transistor 25 whereby the warning lamp 27 is extinguished.

Title: Improvements in or relating to methods of and apparatus for detecting leaks in sealed vessels
Inventor: WINCH GORDON THOMAS
IPC: H01K7/00
Filed: 1961-10-06
Abstract: 945,827. Photo-electric detection of leaks in sealed vessels. GENERAL ELECTRIC CO. Ltd. Oct. 8,1962 [Oct. 6,1961], No. 36014/61. Heading G1A. The invention relates to a method of and apparatus for detecting leaks in vessels containing a gas at or pressure less than atmospheric, for example incandescent-filament lamps, the method comprising the steps of subjecting the gas to a high-frequency electric field to produce a glow discharge in the gas, filtering and modulating part of the resultant output radiations from the discharge to produce two reference beams of different radiation wavelengths, the intensities of the beams varying in opposite phase,and directing the beams on to a common photoresponsive device coupled to a detector circuit so that the circuit output signal varies in response to variations in the relative mean intensities of the two beams. In the embodiment shown, lamps 3 on a conveyer 1 are carried in turn to a testing position T where they are subjected to a high frequency electric field produced by an electrode 4 under the control of an oscillator 5. The resultant radiations are directed by a lens 9 through two filters 7 and 8 which pass a chosen narrow band of the spectrum peaking respectively at 386 mÁ and 405 mÁ, to a photo-cell 11. The resulting beams from the filters are alternately chopped in sequence by a rotating disc 12 having two sets of holes 14 and 15 arranged as shown so that the two beams incident on the photo-cell 11 are modulated in sinusoidal fashion but are 180 degrees out of phase with each other. A neutral density wedge filter 18 mounted in front of the filter 8 is initially adjusted so that the intensities of the light beam reaching the photo-cell 11 are equal when a satisfactory lamp is under test. If air is present in a lamp being tested an unbalance of the two beams will result and a corresponding A.C. signal will be generated by the photo-cell 11. The output signal from the photo-cell 11 is fed through an amplifier 21 and a filter 22 to a clipper 23 which converts a sine wave signal fed to it into a square wave which is in turn fed through a phase splitter 24 to a gate circuit 25, the gate circuit ensuring that only signals of the appropriate phase indicative of an unsatisfactory lamp are fed to a control circuit 26. The gate circuit 25 is controlled by positive and negative pulses derived from the output signals of a photo-cell 28 detecting the resulting chopped radiation of a lamp 29 shining through one set of holes 14 or 15 in the rotating disc, these output signals being fed through an amplifier and differentiator 27. The control circuit 26 which is a flip flop controls a rejector device (not shown) which rejects unsatisfactory lamps.

Title: Circuit for transmitting signals to a television receiver device for protecting the propeller of a water vessel against cavitation
IPC: H04N5/00
Filed: 1973-08-03
Abstract: 1437436 Cathode-ray tube displays RCA CORPORATION 3 Aug 1973 [7 Aug 1972] 36927/73 Heading H4T Signals generated within a (keyboard controlled) desk-top calculator 20, 22, 23, 24 are employed to amplitude modulate a radiofrequency oscillator 26 (operating, e.g. at 61À25 MHz) to-provide a signal suitable for supplying to the aerial terminals of a conventional television receiver 10 on which the results of calculations performed by the calculator are displayed. Horizontal and vertical synchronizing signals S (see also Fig. 3) are derived from circuits 24 and binary data signals W from circuit 23. The latter indicate white with level "1" and black with level "0". During the occurrence of the synchronizing signals S diode D1 conducts so that resistors 38 and 40 are short-circuited and a R.F. level from oscillator 26, determined only by the attenuation introduced by impedance matching # attenuators 32, 34, 36 and 46, 52, 54, is produced for transmission via switch 56 to receiver 10. This level provides synchronizing signals for the latter and is chosen as an 0 db reference (see Fig. 3). During the occurrence of the binary level "0" in the signal W diodes D1 and D2 are non-conductive so that the R.F. output is attenuated by the resistors 38 and 40 to produce the black level signal which is 2À5 db down from the 0 db reference level. When signal W has the binary level "1" diode D2 conducts and shunts a portion of the R.F. signal to ground via resistor 44 to produce the white level signal 18 db down from the 0 db reference level. Capacitors 40 and 50 and D.C. are provided for blocking. Typical parameter values are given.

Title: Electrical drive control system for looms
IPC: D03D51/00
Filed: 1964-09-10
Abstract: 1,073,005. Looms. SOCIETE ALSACIENNE DE CONSTRUCTIONS MECANIQUES. Sept. 10, 1964 [Sept. 20, 1963], No. 37070/64. Heading D1E. In a shuttleless loom a coupling between a member operating the batten and weft inserting means and a driving member is dis engageable so that the shedding mechanism alone can be reversed to remove a faulty weft. As shewn, a flywheel 48 is driven from a reversible motor to operate the shedding mechanism from a sprocket 52, and the batten and weft inserting means through a crankshaft 15 and connecting rods 18, 19 and cams 13, 14 respectively, which crankshaft is normally coupled by a pivoted pawl 54 on cam 13 engaging a notch in a disc 51 secured to the flywheel. The motor is reversed for pick-finding and automatically stopped after each cycle by an electrical control circuit, the coupling pawl 54 being automatically disengaged on the reversal. The reverse drive can only be effected when the loom mechanism is in a suitable position, a cam 75 on the disc 51 co-operating with a switch S 3 . If the position is not suitable a forward drive one revolution switch must be first actuated to reset the loom mechanism.

Abstract: 1465035 Ultrasonic flaw detection D S SHRAIBER B G GOLODAEV B A PALKIN  L M ZAKHAROV M A GENKIN D A FILIPPOV and A F RAZUMOVSKY 27 Aug 1974 37111/72 Heading G1G A method of ultrasonic flaw detection includes radiating signals from a transducer in a probe housing maintained at a constant spacing from an article, receiving reflections from defects therein, scanning the article by relative motion between the housing on testpiece, generating a tracking signal which on retlection from the article surface is received by a pair of transducers which provide a mismatch signal therefrom which is used to maintain an axis of the housing normal to the article surface. Flaw detector 1, Fig. 1, triggers transducer 2 which radiates a pulse into a testpiece 3, and reflections from flaws (e.g. A, B) Fig. 2 (not shown) and detected and indicated therein. Bi-stable 14 is set by the transmitted pulse and reset by the first echo to provide a pulse to coincidence detector 16 which also receives a fixed length pulse of opposite polarity from monostable 15. Detector 16 thus provides a pulse whose length and polarity indicate any error in the housing/testpiece spacing and this is used to operate a reversible motor 18. A separate transducer (not shown) fixed in the housing 4 generates signals which are reflected from the testpiece surface and received by tracking transducers 5, 6. The outputs therefrom, are applied with opposite polarity across a resistor chain 9 whose outputs 13 applied to difference amplifier 11 indicate any mismatch thus causing a motor 12 to tilt the housing. To detect faults at an angle # to the normal, the transducer 2 is set at an angle α such that after refraction at the testpiece surface, the ultrasonic signal meets the flaw normally, (c) Fig. 2 (not shown). To maintain the angle α while the housing tilts, under the control of motor 12 via gearing 30 and link 25 Fig. 4, the transducer 2 is mounted in the housing on an arcuate track of radius equal to the transducer/testpiece separation. When clutch 35 is engaged, movement of a cam 40 mounted on a shaft of the motor 12, moves a pin 39 vertically thus rotating arm 33 about axle 26. This rotates arm 32 to move a fork 36 engaging a pin 37 connected to the transducer. Cam 40 is shaped to maintain a selected angle α for any tilting angle necessary to retain the housing normal to the testpiece.
