Abstract: 1373922 Electro-physical measurements MANUFACTURE BELGE DE LAMPES ET DE MATERIEL ELECTRONIQUE S A 15 Oct 1971 [15 Oct 1970] 48194/71 Heading G1N A capacitive measuring head used to measure the local weight of a yarn, roving, textile strip or tape 5 which passes between the measuring capacitor is comprised of spaced electrodes 1, 2 the latter being positioned between reference electrodes 3', 3" and guard electrodes 4', 4". Electrodes 2, 3', 3", 4', 4" are made by printed circuit techniques on one face of a circuit board on the opposite face of which is disposed further guard electrodes 8 connected to electrodes 4', 4". A further circuit board is disposed in spaced relation and opposing the first board and includes electrode 1 facing the electrode 2 and further guard electrodes 8 on its opposite face. In operation after balancing the bridge circuit, including electrode 1, measuring electrode 2, reference electrodes 3', 3" and windings n 1  of transformer T, in the absence of the yarn 5 the yarn 5 is passed through the measuring capacitor 1, 2. The resulting bridge unbalance signals across resistor R, having an amplitude proportional to the linear weight of the yarn, is attenuated, detected and passed to a synchronous detector to obtain the capacitive component of the signal. The head may be used to alter the frequency of an oscillator circuit instead of used with a bridge circuit.

Title: Improvements relating to fluid flow measuring and indicating

Abstract: 1,121,129. Measuring fluid-flow. CONTACTROL Ltd. Aug. 2, 1965 [Dec. 1, 1964 (2); May 31, 1965], Nos. 48834/64; 48836/64 and 23162/65. Heading G1N. In a fluid-flow measuring device of the type in which the rise in temperature of the fluid when a determined quantity of heat is supplied to it is measured, the measurement is made using semiconductor diodes. The fluid may be heated by a resistor or by a Zener diode. In Fig. 1, resistor 11 is connected to a constant voltage source and temperature-sensitive diodes 16, 17 are connected in a bridge circuit, diodes 16 providing a correction for the ambient temperature of the fluid. In a modification Fig. 3 (not shown) the heater is supplied with pulses at a frequency proportional to the speed of a vehicle on which the device is carried and the flowmeter is provided in the engine fuel supply line of the vehicle to indicate miles per gallon or kilometers per litre. In the circuit shown in Fig. 7 the output from the bridge circuit including temperature-sensitive diodes 100, 101 is supplied to Zener diode heater 107 so that the temperature rise detected by diodes 101 is maintained constant and meter 108 indicates the current, and hence the power, consumed by Zener diode 107. The bridge components are selected so that at zero fluid-flow the current through diodes 101 exceeds that through diodes 100, thus heating the sets of diodes to differing degrees and reducing the Zener diode current to zero. A sensing unit for mounting in a fluid supply line includes an inner barrel portion 22 Fig. 2 (not shown) containing the temperature sensitive diodes 16, 17, which are supported by their leads, and the heating resistor 11, supported between two perforated discs 29. The barrel portion is surrounded by an outer shell 23 defining an annular cavity 30 which provides thermal insulation for the fluid. The shell is clamped to a flange on the barrel portion, and upstream of the flange is a perforated shank portion 25 for equalizing the temperature over the cross-section of the fluid. The barrel is constructed of material having a high electrical and thermal resistance, while the shank, if it is not integral with the barrel, is constructed of material of high thermal conductivity. In the arrangement shown in Fig. 4 fluid entering at 63 is diverted through an inner barrel portion 53A, containing diodes 57, 58 and a Zener diode or resistor 59, and back through an outer barrel portion 50 to a circular groove 52 communicating with outlet 64. The inner barrel portion is of insulating material and the outer barrel portion is lined with insulating material 55, 56.

Abstract: 1533559 Regenerating adsorbent beds W R GRACE & CO 27 Nov 1975 [27 Nov 1974 23 Dec 1974] 48834/75 Heading B1L [Also in Divisions C1A and H5] A bed of adsorbent, e.g. zeolite, having gas, e.g. water vapour, adsorbed thereon is regenerated by passing through the bed a direct electric current or an alternating electric current having a frequency less than 1000 Herz, at a current density low enough to preclude electrolysis of adsorbed gas, and at an energy input sufficient to achieve desorption of the gas through resistance heating. During the regeneration a purge gas or vacuum may be applied to the bed. The electrodes 1 used for bed heating may have an additional function in monitoring the level of gas adsorbed on the bed during the adsorption phase. These may be done by passing an electric current through the bed and monitoring the change in current caused by increasing conductivity as the adsorbed gas content rises. The regeneration may be started at a predetermined such current level or in response to a pre-set timer, dewpoint measurements in the outlet purge gas, bed electrical resistivity signal or regeneration energy consumption.

Abstract: 1365282 Inductive signalling AUSTRALIA DEPARTMENT OF SUPPLY SECRETARY OF 7 Oct 1969 [8 Oct 1968] 49294/69 Heading H4U In a tunnel-tracking system, separate, movable transmitter/receivers, one within the tunnel and one above the ground surface, are coupled inductively to provide both a communication link between them and signals in the surface receiver which correspond to the position of the in-tunnel transmitter. The system permits tracking of the tunnel with the surface instrument offset from the line of the tunnel. Detection is effected by a 50 KHz signal which is frequency-modulated over a 3 KHz bandwidth for communication purposes. Transmission from the tunnel is pulsed from a capacitor to achieve high pulse power. The receiving coil is broadly tuned and the D.C. pulse is processed to be displayed as a proportional measure of distance. To measure an offset distance, the receiving coil is set both horizontally and vertically and the reading applied to a homogram. In the tunnel instrument, a single coil is used for both location pulse transmission and voice communication. Above ground, two receiving coils are used and the communication transmitter requires a high output to compensate for the small dimensions of the tunnel receiver coil. Threshold gating is used to avoid noise interference, and pulses which are used to gate the location field inhibit voice communication while the location pulse is being transmitted.
