Abstract: 816,375. Automatic weight control systems. ZELIWEGER Ltd.,USTER FACTORIES FOR APPARATUS AND MACHINES. Dec. 29, 1955 [Dec. 31, 1954], No. 37288/55. Class 38 (4). [Also in Groups IX, XXXVI and XL (b)] In order to produce a more uniform strip of textile material, for example a draw sliver, the material is drawn through a measuring-device, the instantaneous output of which indicates the weight of the material passing through the device at any instant, a second output is determined from the first by averaging the first over a period of time, the second output is then subtracted from the first to produce a third output representing deviations from the average and controlling the angular speed of a pair of drafting rollers. As shown, textile material 5 is fed by a pair of rollers 19, 20 rotating at constant speed through a gauge 4, two pairs of drafting rollers 21, 22 and 23, 24 and a guide 27, and is then deposited in a can 29. The device 4 comprises a pair of plates constituting a condenser, the capacitance of which varies with the weight of textile between the plates. The condenser is connected in an A.C. bridge circuit 2 which is balanced in the absence of the textile and which, when the textile is present feeds an output to rectifier 6 and high-pass filter circuit 7. The filter circuit gives an output indicative of the variations in the textile weight but independent of long-term variations caused by instabilities of the measuring device itself. The output is amplified at 10 and used to control motor 11 which, through a differential gear 14 alters the drive and thus the speed of drafting rollers 23, 24. The gauge may be actuated behind the rollers and may be of the type relying on the attenuation by the textile of a beam of light passing to a photo-electric cell.

Title: Device and method for calculating temperature and water  vapour pressure
IPC: G01L11/00
Filed: 1974-08-27
Abstract: 1476752 Temperature and vapour pressure determination W R AMBROSE 27 Aug 1974 37453/74 Headings G1D and G1L The temperature or vapour pressure experienced by a medium as a single integrated value over a selected period of time may be determined by means of a device comprising a fluid-tight container containing a cell of constant wall thickness which is permeable to water vapour and contains a particulate desiccant material, the container being filled with water. In a predetermined time interval water vapour is taken up by the desiccant material, the increase in cell weight giving, by comparison with a calibration graph, the required temperature. For determination of the vapour pressure a second cell is employed which is not placed within a container and is situated, in use, adjacent the containerized cell. After a predetermined interval, the increase in weight of the containerized cell gives, as before, the average temperature experienced by the cells and determines which isotherm on vapour pressure versus increase in weight plots is to be employed. A determination of the increase in weight of the second, i.e. non- containerized, cell will then allow direct measurement of the average vapour pressure. The cell may be a cylinder, sphere or cube in shape being formed of a thermoplastic e.g. a polycarbonate, or an epoxy resin. The desiccant may be a molecular sieve material, e.g. activated zeolite 4A. The container may be cylindrical and of glass. The apparatus may be used to determine the temperature of solid, liquid or gaseous material, e.g. soil, water, including sea water or air. Similarly the vapour pressure of soil may be determined.

Abstract: 971,156. Transponder apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Nov. 1, 1960 [Nov. 4, 1959], No. 37511/60. Heading H4L. Interrogating signals are supplied via a common transmitting and receiving aerial 1 to an arm 2 of a magic T 3, a mixer 5 and local oscillator 6, e.g. a klystron, being connected to arms 4 and 8 respectively. The remaining arm 9 of the magic T is provided with a load circuit, for example, a short-circuiting piston. The local oscillator signal is divided between arms 2 and 9 and a portion of the signal reflected by the load 10 is supplied to the mixer 5 together with a portion of the incoming signals from the aerial 1. An I.F. amplifier 12 receives the output of the mixer 5 and supplies a signal to a conventional frequency control circuit 13. When no incoming pulses are being received the circuit 13 supplies a sawtooth voltage to vary continuously the frequency of the local oscillator, reception of a train of signal pulses causing the circuit 13 to reduce the frequency variation so that the local oscillator frequency is maintained substantially constant to provide the correct difference frequency. After the reception of each pulse, a circuit 14 supplied by the I.F. amplifier 12 provides a pulse which temporarily varies the frequency of the oscillator 6 by an amount equal to the intermediate frequency whereby a pulse is transmitted at the same frequency as the incoming pulses. The remote installation receiving the pulses from the transponder receives also echo pulses from the object on which the transponder is positioned and the transponder pulses are arranged to be of longer duration than the echo pulses whereby they may be distinguished on a P.P.I. screen.

Abstract: 871,081. Treating wire electrolytically. CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE. Dec. 3, 1957 [Dec. 3, 1956; Nov. 20, 1957], No. 37677/57. Class 41. A method of electrolytically treating the surface of an elongated material, e.g. a wire 23, comprises placing an area of the surface of the wire in contact with a liquid electrolyte near at least one opening 41 in a cell 39 below the normal liquid level and through which the wire may be passed, preventing by aspiration the loss of electrolyte escaping through the hole 41, and continuously moving the area with respect to the opening 41 so as to bring a new zone of the surface into the electrolyte. Aspiration is provided by passing a gas through a tube 44 from a source at 49, the gas returning electrolyte to the cell 39 at 48 and simultaneously agitating the electrolyte in the cell. The wire 23 is passed back and forth through the cell 39, the tube 44 being suitably apertured, and through washing tubes 72, 74 and drying tubes 73, 75. Liquid and gas are supplied respectively to the tubes 72, 74 and 73, 75, operation of pumps 91, 93, 100, 102 being synchronized with a reversible motor 104 which moves the wire 23 through a pulley 11 so that the appropriate washing and drying tube is supplied with fluid according to the direction of movement of the wire 23. Current is supplied to the cell by an electrode 43 and to the wire 23 by the pulley 71, and a switch 79 may be automatically opened on completion of each passage through the cell 39. A switch 110 controls all the other circuits, and may be automatically operated. Various modifications of cell shape are described. In one, a wire or strip was passed vertically down through an inverted conductive cone into which electrolyte is led, air entering upwardly through the apex of an outer insulating concentric cone to prevent escape of electrolyte. In an example, nickel wire was thinned by passage 150 times at 1.25 cm. per second through a cell containing magnesium perchlorate in alcohol in proportion of 60 gms. per litre. The temperature was 20 C., employing a stainless steel cathode 43 at a current density of 0.5 amps. per sq. cm. A shaped electrode may be employed to impart a desired shape to material being treated. The method is applicable to plating wire or strip as well as removing metal therefrom.
