Title: Improvements in or relating to Apparatus for Locating and Identifying Conductors or Faults in Conductors
IPC: G01R29/08
Filed: 1965-05-25
Abstract: 1,162,811. Locating cables or cable faults. A. J. BAGGOTT. Aug. 25, 1966 [May 25, 1965], No. 22254/65. Heading G1U. Apparatus for locating or identifying a conductor or a fault in a conductor consists of a transmitter circuit for generating and transmitting pulses along the conductor under the control of a switch device whose operation is synchronized in relation to the phase of an A. C. supply, the pulses being grouped in a code distinguishable from noise &c. and detecting arrangements to detect the pulses in the conductor, to enable the conductor or a fault therein to be identified or located. A cable under test 11, 12 is supplied with A.C. at its input 10. This A.C. also supplies a scaler and squaring circuit 15 and phase control 16, the output from which fires a thyristor 19 to connect a capacitor 17 across the cable lines at times predetermined relative to the supply frequency. The capacitor charging current distorts the A. C. waveform, so that a pulse is effectively applied to the cable. By appropriate connection of the scaler and phasing circuits, a coded set of pulses may be so applied to the cable, (see Division H3). The arrangement of capacitor and thyristor may be varied in accordance with the system and type of fault under test. A series arrangement of capacitor, thyristor and diode, with resistors in parallel with these components, is used to provide sharply peaked pulses for locating a healthy cable (Fig. 8). To determine the position of a short circuit in the cable, the capacitor is connected directly across the supply, and can be switched by the thyristor to discharge into the cable (Fig. 9). For an open circuit cable, the charged capacitor is discharged into a resistor connected across the cable, by switching the thyristor Fig. 10 (not shown). The detecting arrangement for sensing the coded pulses in the cable incorporates a search coil, filter and transistor amplifier. The output from this arrangement may be fed to headphones or a visual indicator.

Abstract: 1491704 Transistor absolute amplifier JOSEPH LUCAS Ltd 18 April 1975 [21 May 1974] 22530/74 Heading H3T An absolute value amplifier comprises a differential amplifier 16 with inverting input connected via impedances 15, 23 to the input signal 14 and emitter 19 of transistor 18 fed via load resistors 19, 21 from positive and negative supply rails 11, 12, the output being taken from 22, being a voltage relative to reference potential 13 intermediate the rails 11, 12, proportional to the absolute value of the input relative to point 13, to which the non- inverted input of the amplifier is connected, its output going to the base of the transistor 18. As shown with a PNP transistor the output is negative going; with an NPN transistor (Fig. 2, not shown) it becomes positive going. With reference potential halfway between the rails and resistors 19, 21 equal and the ratio of resistor 2À3 to 15 equal to "b", with input 14 voltage V above 13 either zero or positive, the transistor remains saturated and its collector follows its emitter negative-words, differing by voltage bV; when V is negative the emitter of the transistor moves positively Vb and the almost equal collector current moves output 22 negatively by the same, thus giving output relative to 13 proportional to the absolute input 14 relative to 13.

Title: Wave transmission systems and apparatus
IPC: G01S1/72
Filed: 1947-08-15
Abstract: 658,178. Electro-mechanical delay lines; piezo-electric crystals. WESTERN ELECTRIC CO., Inc. Aug. 15, 1947, No. 22767. Convention date, Aug. 16, 1946. [Class 40 (viii)] [Also in Group XXXVIII] A wave transmission system comprises a transmitting unit which oscillates so as to launch transverse mechanical waves into a transversewave-supporting fluid in which it is placed, and a receiving unit placed in the fluid and capable of receiving transverse mechanical waveenergy. The fluid medium employed comprises a highly viscous liquid, e.g. tar, molasses, polyisobutylene or dimethyl silicone putty. By virtue of the low velocity of propagation of transverse waves, wavelengths are reduced and the apparatus employed may be reduced in size. Also where the system is being used to provide a delay a reduction in the length of the transmission path results. Guided transmission; circular guide. A hollow cylindrical wave-guide 10, Fig. 1, is filled with a suitable wave-supporting liquid. A signal generated at 1 and modulated at 2 is applied to the piezo-electric crystal 8 which launches a transverse wave down the guide at the far end of which it is received, after a predetermined delay, by a further crystal 18, whence it is applied to receiving circuits 20, 21. The elements 8 and 18 each comprise a crystal of Rochelle salt cut in form of a cylinder with its geometrical and optical axes coincident and having a central axial hole. The electrodes are placed one within the hole and the other circumferentially about the cylinder. Upon applying a potential to such a crystal torsional deformation results so that it may be used for the transmission and reception of circular transverse waves. In an alternative arrangement, Fig. 4 (not shown), the transmitter actuates, and the receiver is actuated by, moving coil systems each coupled to a rotatable disc within the liquid. Fig. 5 shows an arrangement comprising a plurality of crystals attached to a backing plate and fed in parallel such that a shearing motion of the forward surfaces of the crystals is produced in the direction shown. Rectangular guide. In a rectangular guide, Fig. 7 (not shown), the transmitting and receiving units may be as shown in Fig. 6. The passage of a transverse wave along a rectangular guide results in the liquid particles approaching and receding from one pair of walls and thus setting up compressional waves unless precautions are taken. To overcome this difficulty the relevant walls may be lined with a layer of paper, sponge-rubber or a similar material so that the liquid can vibrate laterally as though it were unconfined. If the enclosed liquid does not wet the walls, the walls may be etched or ground so that they trap minute bubbles of air to form a resilient layer. This procedure does not alter the impedance of the walls to shearing forces so that in practice all four walls of the guide may be similarly treated. Specifications 464,185 and 658,177 are referred to.

[Class 92 (ii)] For simplifying the calculating apparatus used in determining the future position of a moving target, a quantity proportional to the logarithm of the actual target range, as observed by a range-finder, is set into the apparatus. As shown, a lever 14 determining the setting of a range-finder is moved by a cam 13 driven by a shaft 9, the cam design being such that shaft 9 has turned through an angle proportional to logarithm l=#, being the range. The range can be read on a suitably calibrated dial 10. The shaft 9 is driven by a member 2 frictionally engaging a constantly driven disc 1 and set by screw and nut means 5, 4, actuated by a handle 7. The setting of member 2 from the centre of the disc and of screw 5 is thus proportional to #<SP>1</SP>=l<SP>1</SP>/l and the angular position of the screw may be communicated to the calculating apparatus.

Abstract: 798,279. Electric digital-data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 9, 1955 [Aug. 12, 1954], No. 22902/55. Class 106 (1). [Also in Group XXXVIII] In a " spin-echo data storage system a continuous stream of radio-frequency pulses is applied to the sample and the data is entered by suitably modulating the inhomogeneity of the external polarizing field. It is stated that if a continuous stream of pulses preceded by a prepulse Pp, Fig. 5 (A), is applied to the sample then the stimulated echoes produced as a result of applying a recollection pulse Pr depend upon the values of the integrals: and where O # x # Pr - Pp and where i is the current through the de-homogenizing coils 33, 34, Fig. 1. If for any value of x the value of the second integral differs from the value of the first integral then the echo that would be produced at the instant (Pr + x) is suppressed. In brackets (B) and (C) of Fig. 5, the current i is the same in both the intervals Pp to (Pp + x) and Pr to (Pr + x) and all the echoes are produced. In (D) and (E) there are points of the second interval at which the values of the integrals differ. At these points the echoes are suppressed. In (E) the number of echoes suppressed is indicative of the phase difference between the two i-impulses. An example of the use of this method of measuring phase difference is described for use with echo sounding apparatus (see Group XXXVIII). Specification 798,021 is referred to.
