Filed: 1975-11-21
Abstract: 1503766 Monitoring liquid pressure E I) KRYLOVA and N I BRAZHNIKOV 21 Nov 1975 [21 Nov 1974] 48031/75 Heading G1G The pressure of liquid 11 in a pipe-line 10 is monitored by passing regularly repeated pulses of ultrasonic waves from a transmitter 2 through the pipe wall, liquid 11 and opposite side of the pipe wall to a receiver 3, the output of which is amplified at 9 and shaped at 8 into D.C. pulses (stretched to remove effects of reflected waves); passing reference pulses via a delay 5 and shaper 6 to a circuit 7 which derives a pulsed signal whose pulses are of constant amplitude and whose length varies with the time of travel of the ultrasonic waves through the liquid and hence with the pressure; deriving, by means of an integrator 16, amplifier 17 and reference level setter 18, a D.C. control signal whose amplitude depends on the length of the pulses from circuit 17; and multiplying (or dividing) at 13, converting the resultant signal to a D.C. signal at 14 and recording it at 15. A temperature sensor (32), Fig. 3 (not shown), may be mounted next to the transmitter 2 to provide a compensation signal which is added to (or subtracted from) the signal from 14 before recording. A circuit diagram of the blocks labelled 12 is given, Fig. 2 (not shown). Theory is given on the selection of the time delay and amplitude of various signals to minimise errors due to non-linearity.

Title: Signal translating circuits using field-effect transistors
IPC: H03G3/30
Filed: 1963-12-11
Abstract: 1,074,577. Circuits using insulated-gate fieldeffect transistors. RADIO CORPORATION OF AMERICA. Dec. 11, 1963 [Dec. 17, 1962], No. 49020/63. Heading H3T. In a circuit in which an insulated-gate fieldeffect transistor is employed as an amplifier, oscillator or mixer, signals are applied both to the gate electrode and to a terminal connected to the substrate upon which the source and drain electrodes are formed. If the substrate is reverse biased with respect to both the source and drain electrodes, the substrate input has a high impedance and functions similarly to the gate electrode. Thus by con. necting the substrate and gate electrodes together, either directly, Fig. 6 (not shown), or through a capacitor, Fig. 8 (not shown), the maximtan value of the transconductance and its dependance upon bias voltages can be increased. If the substrate is forwardly biased with respect to the source electrode and reversed biased with respect to the drain electrode the device functions as a bipolar (i.e. junction) transistor whose transconductance can be varied by varying the potential applied to the insulated gate electrode, e.g. for A.G.C. Fig. 10 shows circuit of the type in which the substrate 148 of transistor 140 is reversely biased with respect to both source 142 and drain 144. The circuit operates as a reflex amplifier in a radio receiver, I.F. signals applied at 149 to the insulated gate being amplified by the transistor and taken off by transformer secondary 168. After demodulation, the signal is applied to terminals 153 for application to the substrate, the output being taken from across resistor 164. Fig. 15 shows a self-oscillating mixer circuit of the type in which the substrate-source electrode diode is forwardly biased. The circuit is equivalent to a transistor oscillator in which the collector (drain) circuit is back-coupled to the base (substrate) circuit to maintain oscillations, the oscillation level being modulated to effect mixing by the received signal applied to the insulated gate electrode. Figs. 9 and 14 (neither shown) illustrate mixer circuits which may be used for frequency changing or synchronous detection and in which independent signals are applied to the gate electrode and substrate and a combined output is taken from across a resistor connected in the drain circuit.

Abstract: 1,128,310. Finishing fabrics. SAMCOE HOLDING CORP. 16 Nov., 1966 [19 Nov., 1965], No. 51389/66. Heading D1S. In a method of converting tubular knitted fabric 16 to open width form, the fabric 16 is supplied in a form having initially discernible edge creases and, prior to slitting, is steamed to substantially remove these edge creases. The fabric 16 passes from a container, in which it is held in folded or roll form, over guide rollers and is directed over an edge relocating frame 19 to relocate the discernible creases at the fabric edges along the centre line of the reoriented tube. The frame 19 may be as described in Specification 1128309 and comprises three mutually perpendicular sections 21, 22, 23 and pairs of small diameter guide rolls 24, 25. The reoriented fabric 26 then passes over an internal spreader 27 as described in U.S.A. Specification No. 2.228,001 which exerts widthwise tension on the ridges formed by the initial edge creases. While the fabric is passing over the spreader 27 it is steamed by conventional steam boxes 28, 29. One layer of the flattened tube is then slit along its longitudinal centreline by a rotating knife 30. The slit fabric is directed between driven rollers 34, 35 which are maintained in separated relation so as not to apply nipping or creasing pressure to the fabric but are provided with surface coverings to exert a tractive gripping force on the layers of the fabric. The slit fabric edges are directed outwardly and around a side portion 36 of a frame 37 and under a roller 38. The open-width fabric is wound in a roll 39 supported on rollers 40.
