IPC: F15B21/044
Filed: 1920-02-03
Abstract: 138,629. Pelterie, R. Esnault-. May 26, 1916, [Convention date]. Hydraulic transmission of power. - Means for the hydraulic transmission of power comprise a pump a with an operating-plunger b delivering liquid through a pipe f to a cylinder d having a piston d. The pump may be constructed as described in Specification 3504/15, [Class 102 (i), Pumps &c.], to have a variable output, and the pipe f is connected to air vessels or pressure regulators g. The liguid after leaving the cylinder d enters a reservoir n, from which it returns to the pump through a pipe o, pressure regulators p being provided. The reservoir n is also supplied with liquid by a pump t from a reservoir u so that the pressure in the liquid returning to the pump a is maintained at a value greater than that required to operate an automatic inlet valve to the pump. Air bubbles rise into the upper part of the reservoir n, and escape through an adjustably loaded valve v together with any excess of liquid, the mixture passing by a pipe y to the bottom of the reservoir u, the upper part of which is provided with a vent z or connected to an air pump. In a modification, the reservoirs n, u are of less height, the inlet pipes m, y open tangentially into the upper parts so as to produce a whirling movement of the liquid, and the pipes t<1>, o open tangentially into the lower parts.

Title: Improvements in or relating to distance measuring equipment
IPC: G01S1/02
Filed: 1957-02-01
Abstract: 804,195. Radar; transponder apparatus. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and TAKAHASHI, S. Feb. 1, 1957 [Feb. 1, 1956], No. 3567/57. Classes 40 (5) and 40 (7). The interrogator of a radio distance measuring equipment is modulated by a single sine wave (or a mixture of sine waves) and is simultaneously keyed, the transponder having means for reproducing a continuous sine wave (or a mixture of continuous sine waves) by a filter (or filters) from the interrupted sine wave (or mixture of sine waves) and having means for so interrupting its radiation that its waves reach the interrogator during the period when the latter is quiescent. In the embodiment described 500 c/s. generator 1 with output waveform 12 and 125 c/s. square-wave generator 3 synchronized, see 13, with wave 12 simultaneously amplitude - modulate interrogator transmitter 2 which radiates wave 14. Transponder receiver 4 has output waveform 15; 500 c/s. filter 5 gives an output of waveform 16 and 125 c/s. filter 6 an output of waveform 17. Unit 7 generates a rectangular wave 18 synchronized with waveforms 16 and 17 as shown and the radiation from transmitter 8, on the same carrier frequency as that of the interrogator transmitter, is as shown by waveform 19. Interrogator receiver 9 gives an output of waveform 20 to phase comparator 11, the other input of which is the originating 500 c/s. sine-wave through phase-shifter 10 which is adjusted to give a delay corresponding to 2 D/C, where D is the interrogator transponder distance and C is the velocity of light, and the phase equality at comparator 11 is indicated by a Lissajons figure on a cathode-ray tube therein. A continuous 500 c/s. sine wave may be reproduced in the interrogator from voltage 20 by a filter analogous to filter 5 and the phase comparison is then carried out by a conventional phasemeter. Phase lags in transmitters &c. may be compensated for by conventional methods. A mixture of 500 c/s. and 5000 c/s. sine waves may be generated in unit 1, filter 5 then having 500 c/s. and 5000 c/s. selective circuits and phase shifter 10 having separate circuits mutually connected by a 1: 10 gear ratio; accuracy can thus be increased. It is stated that the invention can be applied to frequency-, or phase-, modulated waves.

Abstract: 124,766. Hooper, J. G., and Hobley, F. R. March 14, 1916. Order and order-type apparatus.-Relates to apparatus for indicating electrically at a distance the position of an arm cr other part of the transmitting-instrument, in which an electromotive force is applied across two selectively adjustable points of a closed resistance by contacts carried by the transmitting-arm, current being tapped from the resistance at three fixed points and conveved to three coils at the receiving instrument, where the direction of the resultant electro-magnetic field corresponds with the position of the transmitting-arm. Usually, the transmitter arm is angularly movable over an annular resistance, and the direction of the resultant field at the receiver is indicated by .suitable means such as a pivotally-mounted permanent magnet. In the present case, the coils of the receiver take the form of a three-phase winding J, Fig. 4, mounted on a drum of non-magnetic material, such as aluminium, rotatable between the poles of a fixed magnet K. Current is passed to the coils through brushes N<1> and rings N. and the spindle J<2> may carry a pointer. The resistance of the transmitter may be arranged in two crossconnected linear portions a, Fig. 5, along which the transmitting arm b is arranged to slide. The resistance gradient may be uniform or otherwise, and, if desired, a variable resistance a<5> may be introduced between a tapping point T' and the receiver, to secure any required variation from uniformity. An annular resistance is also described, made in sections connected to contact studs arranged in three concentric rings over which the transmitter arm wipes, the studs being staggered to give fine sub-division

Title: Electret sensing devices for temperature and stress variations
IPC: G01L1/16
Filed: 1976-02-03
Abstract: 1537154 Measuring stress and temperature electrically MINNESOTA MINING & MFG CO 3 Feb 1976 04227/76 Heading G1N A temperature or stress sensor comprises two electret layers and is arranged so as to compensate for stress or temperature variations respectively. Temperature sensor Fig. 2 comprises two oppositely poled electret layers 2, 3, having both pyroelectric and Piezo-electric properties, in contact with equal area conducting layers 7, 4, 8 layer 4 being relatively stiff with respect to layers 7, 8. A sensing circuit 10 such as a voltmeter or ammeter is connected as shown to the layer 4 and grounded layers 7, 8. When the temperature of the sensor is varied uniformly a uniform distribution of charge as shown appears on the surfaces of the electrets which is detected by circuitry 10. If any bending of the layers occurs conductive layer 4 serves as a point of zero compression or tension and layer 2 is compressed and layer 3 extended. Due to the Piezo-electric properties of the electrets positive and negative charges on the outer and inner surfaces of layer 3 and negative and positive charges on the outer and inner surfaces of layer 2 appear which cancel out. In an alternative embodiment Fig. 4 (not shown) the two electret layers are poled in the same direction and the sensing circuit is connected across the outer layers 7, 8. Stress Sensor Figs. 5 to 7 (not shown). In one embodiment the arrangement is the same as in Fig. 2 except that the electrets are poled in the same direction. The distribution of charges due to temperature changes cancel out whereas bending of the sensor produces a potential across the sensing circuitry. In the arrangemement of (Fig. 7) the two electrets are poled oppositely and the sensing circuitry connected across the two outer layers.
