Patent GB-1303247-A (GB)
IPC: G01N33/30
Filed: 1969-07-15
Abstract: 1303247 Testing lubrication properties JOSEPH LUCAS (INDUSTRIES) Ltd 3 July 1970 [15 July 1969 21 Feb 1970] 35485/69 and 8423/70 Heading G1S The lubrication properties of a liquid are tested by pouring the liquid onto a plate, rotating the plate so that the thickness of the liquid decreases and interference fringes are formed, placing a probe in contact with the plate as the last interference fringe passes a predetermined point and measuring the length of time taken for the film between the probe and the plate to be destroyed. The speed of the plate is preferably reduced as the probe is applied. In one form of apparatus Fig.1 the probe 24 is mounted on a resilient arm 23 forming part of a frame-work which is pivotally mounted by rods 22 having conical recesses, (not shown), at their ends resting on balls, (not shown), in recesses on a casing for the device. The probe 24 is biased towards the plate 14 to which the liquid is applied by weights 29. When the liquid film is destroyed, the resilient arm is flexed as a result of the frictional force between the probe 24 and plate 14, and pin 31 moves relative to sensing coil 32 to cause an impulse in an external circuit to indicate destruction of the film. In a second form of apparatus (Fig.3) the probe 45 is mounted on the end of pivoted arm 44 and weights are applied to pan 53 to bias the probe towards the plate 43. Destruction of the film causes capacitor plate 51 to move relative to plate 52 and produce a signal in an external circuit.

Title: Displacement transducers
IPC: G01D5/22
Filed: 1969-10-06
Abstract: 1319586 Displacement transducers; proximity detectors FINDLAY IRVINE Ltd 24 Sept 1970 [6 Oct 1969] 49045/69 Heading G1N The extent and direction of displacement of a member 14, e.g. attached to a tool or workpiece, from a datum is determined by apparatus including a sensing head 13, Fig.3 (not shown), having two coils connected in a bridge with the two secondary coils 11, 12 of a transformer. The output of a gate 17, is a half-wave voltage whose polarity and amplitude are respectively indicative of the direction and extent of displacement of the member 14 within a pre-set range of displacement. This signal is applied via an integrator 19 to an indicator, recorder or control apparatus connected at terminal 20. A signal is also derived from a coil 22 connected across a potentiometer 41, the output of amplifier 21, Fig.2 (c) being compared in a discriminator 23 with a threshold to provide a signal 2(d) when the member 14 is within a pre-set proximity zone to the datum. The output of discriminator 23 is applied to two AND gates 26, 27 which have their other inputs connected to the outputs of a zero detector 32, Fig.2(e) and an inverter 33. Depending on the direction of displacement, one of the AND gate outputs, Fig.2(f) and 2(g) triggers a bi-stable 31 to produce an output at the appropriate terminal 29, 30 Figs.2(h) and 2(j) which remains even if the member 14 is displaced outside the defined proximity zone. When the member 14 is within pre-set close limits of the datum, on output, Fig.2(u), is received from an AND gate 39 having its inputs provided by the output of discriminator 23, and the outputs of detectors 35, 36, Figs.2(k) and 2(1). The output of discriminator 23 may also be inverted at 43. The signal from driver 25 may also be fed back to the oscillator 10 to thereby control the amplitude of the signal from integrator 19 to provide compensation for changes in gaps between the head 13 and the member 14.

Title: Tube coiling apparatus
IPC: B21D11/06
Filed: 1971-11-19
Abstract: 1320428 Coiling helices D MILES and I M MUSSON 19 Nov 1971 53937/71 Heading B3E  Apparatus for helically coiling tubing comprises a cylindrical member 59 having a helical groove 60, means for securing a tube near one of its end relative to member 59, means for rotating member 59, and a yoke, Fig. 3, having a grooved roller which with groove 60 define a circular aperture the size of the tube, and having further rollers 92, 96, 102 engageable in groove 60 so that as member 59 is rotated, the yoke moves axially and bends the tube into the groove. As shown, a housing 50 supports member 59 on shaft 56 driven through belt 54 by electric motor 52. Uprights 64 and cross-beam 65 support pulleys (not shown) for a cord 89 attached to the yoke by eyelets 88 and to a counterweight (not shown). The yoke includes a removable strap 82 and arms 84, 86 having rollers 85, 87 bearing on uprights 64 to prevent the yoke rotating. The tube is clamped at 62 on a flange 61 of member 59, and the yoke is placed around the member 59 with the grooved roller (not shown, but coaxial with roller 102, Fig. 3) and groove 59 enclosing the tube, the arms 84, 86 resting in adjustable platforms 68. A further grooved roller 103 prevents vibration of the tube. As member 59 rotates, the yoke rises and bends the tube into groove 60 until the yoke arm operates switch arm 70. This makes effective a switch 74 so that the motor is stopped when member 59 is next in a preselected angular position. The yoke is removed and clamp 62 released. The operator restarts the motor, holding the tube against rotation so that it is wound off the member 59, and then manually trips switch arm 70 to restop in the selected position. The tangentially extending end portions of the coil are then bent as required using a core spring to form e.g. diametrically extending coil ends as in a hot water storage tank heat exchanger.

Title: Apparatus for the measurement of reflection coefficient and  the complex parameters of multiport electrical networks at  radio frequencies
IPC: G01R27/28
Filed: 1972-02-10
Abstract: 1333894 Measuring network parameters D WOODS 10 Feb 1972 6390/72 Heading G1U A coupling, for use in measuring multi-port network parameters, comprises a coaxial inlet socket 9, Fig. 2, an inner conductor 11, 10, which includes two resistive portions 3, 4 separa+ed by a metallic portion 5, two measuring probes V 1  and V 0 , and a double supply part 14, 17 allowing an r.f. signal V s  and a D.C. bias to be injected into the juntion 5 between the resistive portions 3, 4 of the inner conductor. The resistive portions 3, 4 of the inner conductor are surrounded by metal cylinders 20 supported on the cylindrical body 1 of the coupling by a thin film dielectric 21, and in order to reduce resistance variation with frequency and to make this screen effective down to about 30 kc. /s, the thin film dielectric is paralleled by two rings of electrolytic capacitors 23, 24. The inner conductor is supported by a dielectric disc 7 mounted in the cylindrical body 1 and by a dielectric bush 8 mounted inside the inner cylindrical screens 20. Finally, the coupling includes plungers 22, shown retracted, which may be moved radially inwards to connect the central metallic portion 5 with the cylinders 20. In use the device can operate in two modes; in the first - referred to as the "active mode" - with the plungers 22 withdrawn as shown an excitation applied to the double inlet part 14, 17 excites a network under test connected to the socket 9, and in the second - referred to as the "passive mode" - the plungers 22 are inserted thereby providing a matched termination for the network connected to socket 9. Thus the coupling behaves in the active mode as an active source of substantially matched resistive source impedance and in the passive mode as a matched resistive termination, the change from mode to mode being effected, e.g. by a solenoid operating the plungers 22. A typical use of two of the coupling devices, and their equivalent circuits, is shown in Fig. 6. With switches S 1  and S 2 , which are consituted by the plungers 22, in the position shown, a signal V s  is first injected into the left-hand coupling and the voltages V 0 , V 1 , and V 2  are measured, thereby allowing the forward reflection co-efficient to be calculated, and then the switches are reversed, the signal V s  is injected into the right-hand coupling, similar voltages are measured, and the reverse reflection coefficient is calculated.
