Abstract: 1275566 Releasable fastenings T M MARGESON and H W DENNY 12 Aug 1969 [15 Aug 1968] 40229/69 Heading E2A An electrical control circuit includes a single frequency generating means 16 forming a first part of said circuit, single frequency matching means 32 forming a second part of said circuit for receiving said single frequency and generating a control signal when said single frequency is received, each of said frequency means including a crystal control element for permitting precise frequency matching, the control element of the first part of said circuit being insertable therein or removable therefrom to activate or deactive the circuit respectively. As shown the means 16 is connected to an amplifier unit 26 which amplifies the oscillations from the means 16 and these are passed along a co-axial cable 28, 30 to the means 32 the crystal control element of which has the same operating frequency as the crystal control element 22 of the means 16 thus the means 32 will only pass a signal through it when the element 22 is in the means 16; from the means 32 the signal is passed through a unit 34 where it is amplified and subsequently rectified and the resulting direct current is carried along lines 36, 38 to the control gate of a thyristor 42 the signal turns the thyristor on so that a relay 46 is energised to cause its contacts 50 to close to control a load connected to the contacts by lines 54, 56. The circuit can be used for controlling the operation of the ignition coil of a motor vehicle in which case the element 22 is mounted in a member similar in shape to a key and which can be plugged into a socket connected to the remainder of the circuit; the member shaped like a key also acts to connect a battery to the circuit when it is plugged into the socket as well as connecting the element 22 into the circuit. The circuit can in addition be used to control a bonnet lock which is only released when the key shaped member is in the socket so that the circuit cannot be bypassed. All the components of the oscillator unit except the crystal and the first amplifier unit can be mounted on the socket with the remainder of the circuit connected to the socket by the co-axial cable.

Title: Process for the treatment of effluent
IPC: F23G5/02
Filed: 1977-10-04
Abstract: The waste waters are treated by oxidising the organic pollutants at temperatures above 750 DEG C and separating the inorganic substances which are largely free of organic impurities from the flue gases. They are concentrated in one stage (2) or in a plurality of stages (2, 5) in an evaporation plant (2, 5) to give a concentrate having a maximum residual water content of 50% by weight, and said concentrate, before it is fed to a suitable combustion device (26), is processed prior to the last evaporator stage (5) or immediately after discharge from the evaporator (2, 5), without intermediate storage in a dispersion machine (15) and with the addition of a first amount of a liquid fuel, to give a storable, pumpable and atomisable dispersion. The process is suitable for reprocessing waste waters such as result from the production of colorants, colorant intermediate products, for example the so-called letter acids, and also plastics and plastic precursors, for example caprolactam and chloroprene. <IMAGE>

Abstract: 1,017,755. Film actuated cine control devices. CONTINA BUREAUX UND RECHENMASCHINENFABRIK A.G. Oct. 31, 1962 [Nov. 18, 1961], No. 41262/62. Heading G2E. A cine camera or projector automatic filmthreading device comprises electrical contacts in the form of guide rails 17, 18 bridged by spring 19 which is raised by the passage of film end 42 to break the circuit of electromagnet 20 whose armature is then drawn towards point 37 by spring 36, this motion rotating stub shaft 27 through rack and pinion 34, 35 and being halted when nose 38 reaches stop 39. End-face 28 of shaft 27 carries pins 29, 30, pin 29 engaging slide plate 31 which carries upper guide 1 and lower inner guide 4, and pin 30 engaging slide plate 32 which carries inner guide 2 and lower guide 3. In Fig. 1 the upper and lower guides are closed up to form film channels 10, 15 through which the film is intermittently fed by claw 14 moving in slot 13 in guide 11. When the circuit is broken as above, pins 29, 30 are rotated with shaft 27 and the corresponding motion of slide plates 31, 32 open channels 10, 15 to allow film loops to form. The armature motion may alternatively be used to operate a film threading device as in Specification 987,881 in order to connect the film to the storage spool. Apertures may be cut in the film to permit closing of further electrical contacts and hence the control of room lighting or sound tapes.

Title: Improvements in continuous tone-controlled squelch system
IPC: H03G3/26
Filed: 1958-12-22
Abstract: 910,772. Radio signalling; muting. GENERAL ELECTRIC CO. Dec. 22, 1958 [Jan. 2, 1958], No. 41276/58. Class 40 (5). A radio receiver is provided with two muting circuits, one responsive to random noise and the absence of the carrier, and the other responsive to the absence of the correct calling tone for the receiver. The receiver is included in a system in which several users share the same radio frequency channel, and the muting circuit responsive to the calling tone is automatically disabled prior to making a call so that the user may listen before transmitting to prevent interference with the other transmissions. As shown, the signal input, which consists of audio signals plus a predetermined tone, from the discriminator of an F.M. receiver is supplied via terminal 5, filter circuit R4, R5, Cl, C2, and coupling capacitor C6 to an audio amplifier V6, and also directly to an amplifier V5 which is tuned to the calling tone. The output of V5 is applied to the control grid of V6, the resistor R6 being adjusted to ensure that the tone signal from V5 is in phase opposition to the tone signal supplied via coupling capacitor C6 so that no tone signal appears at the audio output terminal 7. The output of V5 is also rectified at V7 and supplied to the control grid of a triode V4. In the absence of an input signal the noise at terminal 5 is high and is supplied to a noise amplifier V1 which amplifies frequencies from 4 kc/s. to 20 kc/s. The output of V1 is rectified at V2 and supplied to the control grid of a normally non-conducting triode V3 whose anode in common with the anode of triode V4 is connected to the control grid of V6. The rectified noise voltage causes V3 to conduct and the resultant drop across resistor R10 biases the amplifier to cut-off. When the carrier is present but there is no calling tone of the correct frequency the control grid of V4 is at a positive potential, thus again biasing the valve V6 to cut-off, but when the correct calling tone is received the resultant negative voltage from the rectifier V7 biases V4 to cut-off and allows the amplifier V6 to conduct. When the operator lifts his microphone to transmit, the switch S1. is moved to position 11 thus disconnecting the muting circuit responsive to the calling tone and enabling the operator to listen for any calls being made on that carrier frequency. Alternatively, a three-position switch may be incorporated on the microphone making it necessary for the operator to switch from the " tone " position and through the " listen " position before moving to the " transmit " position.

Abstract: 1,209,238. Valves. JAMESBURY CORP. 3 Sept., 1968 [1 Sept., 1967], No. 41917/68. Heading F2V. A rotatable ball plug valve is provided with a seat ring comprising radially inner and outer sealing portions such as "A" and 22, Fig. 2, or 36, 37, Fig. 5, which effect sealing respectively with the ball plug 15 and with the valve housing 10, and a core member particularly of metal of high tensile strength having branched parts such as 21a, 21b or 35, 35a for confining that sealing portion which engages the ball, the branched parts extending to positions where they closely approach the surface of the ball. In the case of sealing materials subject to cold flow e.g. plastics, such flow away from the sealing region at the ball is thereby reduced. The part 21a acts resiliently and in assembled position is slightly deformed, Fig. 9 (not shown). The parts 36, 37 may be bonded to the member 35, 35a or may be loose, and the part 21b may be separate from the part 21, Figs. 3, 6, and 10 (not shown).

Filed: 1959-12-10
Abstract: 925,308. Electric selective signalling systems. BELL PUNCH CO. Ltd. Dec. 10, 1959, No. 42046/59. Class 40 (1). [Also in Groups XIX and XL (c)] An electronic counter comprises a chain of cold-cathode trigger tubes, the anode of each of which is connected to a cathode of a multicathode indicating tube. As described, for a single decade stage, ten cold-cathode trigger tubes 2, 3 . . . 4, 5, are connected by coupling circuits including capacitors 12, 14 . . . 16, 18, the anode of each tube being connected to a cathode 1, 2 . . . 9, 0, of a multi-cathode indicating tube 1. Positive pulses to be counted are applied at a terminal 26, and inverted by a tube 6, the output of which is applied to the anode of the tube 1. The magnitude of the potential difference V 3 -V 0  across the circuit is such that a glow discharge is maintained between the anode and one cathode of the tube 1 and in the associated trigger tube 2-5. Assuming the discharge in the tube 1 is to its " 1" cathode, the drop in potential at the anode 7 of the tube 1 due to the next input pulse cuts off the tubes 1, 2 and when, at the end of the input pulse, the potential rises, the remanent ionized path from the anode 7 of the tube 1 to the " 1 " cathode causes a small current to flow to the cathode "1" which is applied through the condenser 14 to fire the trigger tube 3, causing the discharge in the tube 1 to pass to the " 2 " cathode. To ensure that the first pulse of a series causes the discharge in the tube 1 to be to the " 1 " cathode, a normally open switch 11 is closed and an input pulse with a gradual decay is applied to the terminal 26. A carry pulse is obtained from the resistor 21 in the circuit of the " 0 " cathode of the tube 1 and trigger 5, the provision of a difference diode 22 and R.C. time circuit comprising resistors 23, 25 and a capacitor 24, ensuring that an output pulse is obtained at terminal 27 of the required length to operate a subsequent decade stage (not shown). Specification 925,309 is referred to.

Abstract: 1322933 Semi-conductor devices HITACHI Ltd 3 Sept 1970 [5 Sept 1969] 42295/70 Heading H1L A structure for preventing parasitic IGFET action includes a highly doped region of the same conductivity type as the substrate, which region lies beneath the insulating material adjacent the IGFET and forms PN-junctions with the source and/or drain thereof, in order to prevent parasitic action between the source or drain region of the normal IGFET and other regions via the metal connections formed on insulating material around the normal IGFET. The doping of the highly doped region is selected to be between 1À5 Î 10<SP>16</SP> and 2 Î 10<SP>17</SP> atoms/c.c. so that in the parasitic IGFET formed the PN-junction with the source or drain region, has a breakdown voltage which lies above the supply voltage of the circuit, and the threshold voltage of the parastic IGFET also lies above the supply voltage, preventing parasitic action since the parasitic IGFET does not conduct. In an embodiment, parastic action between two IGFETs 31, 32 is prevented by the inclusion of a highly doped region 47 which overlaps the drain region 34 of IGFET 31 and part of the substrate occupied by the parasitic IGFET. The substrate may be of silicon, the insulating material of silicon dioxide, silicon nitride or aluminium oxide. Other embodiments include an inverter circuit and a protective diode arrangement for an IGFET.
