Title: Improvements in or relating to electrical connectors
Inventor: RICHARDS CLAUDE LANGDON
IPC: H01R12/67
Filed: 1965-10-27
Abstract: 1,109,858. Tape cable connectors. PAINTON & CO. Ltd. 20 Oct., 1966 [27 Oct., 1965], No. 45533/65. Heading H2E. A tape cable connector comprises means to relatively displace the cable and contacts during assembly so that spring-urged teeth on the contacts plough through the cable insulation and contact the conductors. In one arrangement (Fig. 1) a base 2 for the cable 4 has upstanding sides with inwardly projecting guides 10 to slidingly receive a member 21 carrying phosphor bronze contacts 26. Each contact 26 is saw-toothed at the end of a resilient arm 31 and has a terminal blade 36 and bent over arms 147 to receive a mating socket or blade terminal. The contacts 26 are located by lugs 41 in slots in member 21, and alternate contacts are cranked so that the terminals 36 form two staggered rows 37, 38. In assembly, the cable 4 is laid on the base 2 and clamped against a stepped end 6 by a correspondingly stepped member 13 secured to the base 2 by hollow screws 18. Member 21, complete with contacts, is slid into position and in so doing the contact teeth plough through the cable insulation. Member 21 is secured by screws 50 and has a polarizing lug 39. In a second arrangement (Fig. 20), two rows of contacts 84 are located in grooves in member 50 whose end is shaped to mate with an indentical connector. The cable 53 is placed over the bevelled surface 63 of a second member 51 which is then bolted to member 50 to clamp the cable at the stepped region 68 and to hold it against the teeth of the contacts. Projections such as 80 on a third member 52 enter apertures in member 51 and drag the cable up the surface 63 against the contact teeth. It is stated that the connectors may be adapted to mate with a printed circuit edge-connector.

Title: Improvements in or relating to measuring methods and apparatus
Inventor: COLLETT GRAHAM DAVID
IPC: G01B7/06
Filed: 1963-11-19
Abstract: 1,064,499. Measuring dimensions. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Feb. 19, 1965 [Nov. 19, 1963; April 27, 1964], Nos.45604/63 and 17311/64. Heading G1N. Apparatus for measuring the thickness of a layer of a penetrable material in contact with a different penetrable material comprises an  electrode for penetrating the materials, means for monitoring an electrical property associated with the materials using the electrode, and means for indicating the position of the electrode. The electrical property monitored may be the resistance or the electrochemical potential of the material. For measuring the thickness of slag on molten steel two electrodes are provided, vertically spaced apart. The electrodes may be connected to a source of voltage and changes in the resistance between the electrodes monitored as they are passed into the material. The resistance will be infinite until the upper electrode reaches the slag, and will then fall to an intermediate value. When the upper electrode subsequently reaches the molten steel the resistance will fall to a lower value. The position of the upper electrode may be indicated by a pointer attached thereto, or a motor driven pointer may be driven at constant speed during passage of the electrode through the slag. The monitoring circuit may include a pair of relays actuated as the upper electrode enters and leaves the slag layer. If the electrodes are spaced by more than the maximum slag thickness normally encountered, the electrochemical potential difference between the electrodes may be monitored, being absent 250 millivolts when the lower electrode is in the molten steel and the upper electrode is in the slag. If the electrode spacing is less than the slag thickness the resistance may be monitored to indicate contact between the upper electrode and the slag and the electrochemical potential difference monitored to indicate contact between the upper electrode and the steel. The lower electrode may be fixed to always contact the steel and may be constituted by a ladle stopper rod or by the ladle itself. A modified arrangement uses an erodable upper electrode in the form of a mild steel rod or tube. This is passed into the melt so that the portion immersed in the steel will be melted while that in the slag layer is not. The melting may be monitored by measuring the potential difference between the electrodes as before, a potential difference being set up only when melting is complete. The upper electrode is then withdrawn and the resistance between the electrodes is monitored to indicate when the upper electrode leaves the slag. Melting need not be monitored directly. The electrode may be left for a time sufficient for melting and then withdrawn. If melting is complete the resistance between the electrodes will increase immediately withdrawal is started.

Title: Electrically controlled fuel injection systems for interanl combustion engines
IPC: G01F1/68
Filed: 1972-10-06
Abstract: 1403406 Electrical fuel injection system for I C engines ROBERT BOSCH G.m.b.H. 6 Oct 1972 [8 Oct 1971] 46096/72 Heading G3N In an I.C. engine electrical fuel injection system the injection quantity is controlled in dependence upon air intake quantity determined by a device which includes a temperature dependent resistor 3 located in the air intake manifold 25 and supplied with a heating current having a D.C. portion and a portion of periodically varying magnitude, one of these portions having zero value when the air quantity is zero and being increased by a regulator as the air quantity increases to maintain the temperature of the resistor constant. As shown, in an intermittent fuel injection system, the resistor 30 is arranged in a bridge with resistors 33, 34 and 35, and is supplied with a basic direct heating current which is adjusted by resistance 36 to maintain the temperature of resistor 30 at its desired constant value in the absence of air flow, and an alternating current supplied by a controlled oscillator 38 which is controlled by a differential amplifier 40 connected to a diagonal of the bridge. Thus as the air quantity increases to unbalance the bridge, the amplitude of the alternating current is increased to rebalance the bridge. The A.C. component across resistor 34 is amplified at 45, rectified at 46 and applied to an integrator 47 which receives a signal from a bistable switch 49 triggered in synchronism with engine rotation. During the integrating process a capacitor is charged with a direct current corresponding to the heating current, the discharge time of the capacitor then determining the injection pulse duration. In an alternative, Fig.3 (not shown), the varying magnitude heating current portion is provided by heating current pulses of constant duration and of a frequency adjustable by a regulator connected to a diagonal of the bridge. To control the duration of injection pulses, measurement pulses of constant duration are derived from the heating pulses and the measurement pulses are applied to a modulator which lengthens the pulses or the pulse frequency increases. During the rotation of a predetermined crank-shaft angle a constant current source charges a capacitor during the modulated pulses, the charge on the capacitor being converted by means of a constant current source into an injection pulse. An automatic re-setting device may be provided in which, when the engine ignition is switched off, the bridge and the regulator remain connected for a period of time to the battery of the engine.

Title: Circuit breakers
IPC: H03K17/30
Filed: 1963-11-22
Abstract: 1,022,964. Protective arrangements. STANDARD TELEPHONES & CABLES Ltd. Nov. 22, 1963 [Nov. 29, 1962], No. 46217/63. Heading H2K. A protective arrangement comprises a semiconductor switch 12 between a power supply 10 and a load 11, and a trigger device 14 for switching the switch 12 " off " and responsive to the difference between a reference voltage P1 derived from the supply 10 and the voltage P2 applied to the load. In the arrangement shown the switch 12 comprises parallel transistors 25, 26 with negative feed-back resistors 27, 28 to balance the load current between the transistors. Under normal conditions, the voltage P2 applied to the emitter of a trigger transistor 24 is more negative than the reference voltage P1 applied to the base of that transistor so that the transistor 24 is non-conducting, a " driver " transistor 13 is conducting and the transistors 25, 26 conduct. Under short-circuit conditions of the load 11, the voltage across the load is reduced so that voltage P2 becomes less negative and the transistor 24 conducts to change the potential at the base of the transistor 13 which becomes non-conducting and switches off the transistors 25, 26 to interrupt the load current. This is followed by the release of a relay RY1 which opens its contacts RY2 in the load circuit. Resetting is effected by operating a push-button switch SW1, SW2.

Abstract: 1,072,372. Photo-electric measurement of transmissivity. H. HESSE. Dec. 11, 1963 [Dec. 13, 1962], No.47145/62. Heading G1A. In apparatus for measuring the optical transmissivity of test samples having means for periodically resetting the calibration an indication is given if the resetting means is moved beyond a certain point. In one embodiment light from a source 5 is directed through a vessel 9 to a photoelectric detector 10 coupled to a meter 13. The lamp is energized through a voltage stabilizer 1 and the arm 8 of an adjustable potentiometer 4. To calibrate the apparatus the vessel 9 is filled with distilled water and the potentiometer adjusted until the meter reads zero absorption. Replacement of the water by the test sample or series of samples then enables absorption measurements to be made. Due to the ageing of the lamp and detector or the dirtying of the surfaces of the test vessel, the voltage it is necessary to apply to the lamp at successive calibration operations gradually increases until it reaches a point at which the apparatus readings are no longer reliable and other action has to be taken. To indicate when this point has been reached the arm 8 of the potentiometer is arranged to then close the circuit of a warning light 15. Arrangements may also be made to indicate when variations in the voltage stabilizer output occur. Instead of varying the source intensity the source may be supplied with a constant voltage and calibration adjustment effected by the use of an iris diaphragm or grey wedge. The attenuator control being arranged to give an excessive adjustment indication in one of the ways mentioned.

Abstract: 1,157,996. Taking up surplus material. GLANZSTOFF A.G. 25 Oct., 1966 [10 Nov., 1965], No. 47877/66. Headings DID and D1F. A device for taking up continuouslydelivered material while the collecting bobbin is being changed, comprises two coaxial nozzles, one subject to pressure and one to suction, and so arranged that the pressure and suction effects reinforce one another. A housing 1 has tightly secured to it a tube 3 and a head 5. The latter carries a tapering nozzle 8 projecting into an outwardly flared conical end 9 of the tube 3. The annular space 14 between the housing and tube terminates in a chamber 15 surrounding the nozzle 8 and conical end 9. A passage 16 in the head leads from the chamber 15 to a jet 17 just above a mouthpiece 7. The tube 3 is connected to suction and the annular space 14 to pressure. The effect of the pressure in chamber 15 which generates a downward current between the nozzle 8 and end 9, reinforces the effect of suction at the nozzle 8. Pressure is also produced at the nozzle 17 acting downwardly on the mouthpiece 7, i.e. in a direction which reinforces the suction effect. Material passing to two take-up bobbins, is, when the bobbins have to be changed, diverted to come between the mouthpiece 7 and nozzle 17 and is drawn through the tube 3 to be collected in a waste receptacle. The device may be fixed near the yarn path and be put into operation by an electric circuit, or it may be a manual appliance.
