Title: Improvements in or relating to fault locators
IPC: G01R31/08
Filed: 1965-09-01
Abstract: 1,063,418. Pulse echo cable testing. PATENTED DEVICES (PROPRIETARY) Ltd. Sept. 1, 1965 [Sept. 2, 1964], No. 37373/65. Heading H4D. A pulse echo cable tester is so designed that when testing a main feeder cable having neutral and line conductors 12 and 13 respectively, feeding several T'd-off services, the echoes from the T-junctions do not pass to the receiver. This is particularly useful if the length of the T service and the distance between T-junctions is the same, such that echoes from the end of the T service, and the next T-junction arrive simultaneously at the receiver and are thus indistinguishable. In the embodiment shown a pulse is sent down the cable conductors, via centre tapped primary winding 10. Currents are in opposition in the two halves of the winding so no pulse appears in secondary winding 17. A T-junction will reflect a pulse on both conductors simultaneously to produce equal currents in opposition in the two halves of the primary winding. Again no pulse appears at the secondary winding, or at the receiver. A fault on only one conductor however, will produce echo currents which do not cancel out in the two halves of the primary winding, and the resultant pulse appears at the secondary winding for display at the receiver. In a second embodiment, Fig. 2 (not shown) for a cable having one neutral conductor 21 and three line conductors (22), (23), (24), an echo on the neutral line, introduces a current in a first secondary winding (30) of a transformer (28), and a simultaneous echo on any of the line conductors, induces, via an OR-gate arrangement, a cancelling current in a second secondary winding (30), in series opposition to the first winding. The receiver connected to the secondary windings thus receives no signal. Switch diodes (29) allow only positive or negative echoes to be investigated at will, while diodes (26) isolate the short circuit connection of the conductors from the transformer (25). The pulsing unit is removed as soon as its pulse has been transmitted. In a cable having no T-junctions, the invention may be used to detect any differences in the impedances of the cable conductors. Since the transmitted pulse is prevented from passing to the receiver, echoes from very near impedance discontinuities may be investigated.

Abstract: 1398640 Photo-electric control of rollers KRAUSS-M AFFEI AG 10 Aug 1972 [20 Aug 1971] 37393/72 Heading G1A [Also in Division G3]  The thickness of the mass of plastics material 4 being rolled by calender rollers into a thin sheet, is monitored photo-electrically so as to prevent the possibility of the rollers contacting one another. The position of the edge of the bank 4, indicative of the thickness, in a plane at right angles to that containing the roller axes, is measured by repetitively scanning a light beam 5 across the edge, the unblocked radiation being sensed by cells in linear array 6. The source 1 is a laser which in Fig. 1 is itself oscillated angularly. In other arrangements, it is oscillated on a rectilinear path, Fig. 3 (not shown), or a fixed source co-operates with an oscillated mirror, Fig. 2 (not shown) or an oscillated refraction plate, Fig. 4 (not shown). The varying detector output is used for control on the roller gap and alarm purposes, if necessary. Further, photo-electric systems at each edge of the rollers monitor the roller gap, transverse to the roller axes. Theses are used for starting up the system and only allow switching over to the control system of Fig. 1 when a roller gap below a certain level is reached, indicating that a suitable plastics mass has been formed. The measured thickness may be used in retroactive control to the roll drives, adjustment drives, a roll bending device, or a strip cutting device of a preceding set of mixing rollers. Optical and acoustic alarms may be provided.

Filed: 1928-12-19
Abstract: 319,341. Compagnie Internationale pour la Fabrication des Essences et Petroles. Sept. 21, 1928, [Convention date]. Hydrocarbons, distilling.-In the catalytic cracking at normal' pressure of petroleum oils &c., the oils, vaporized in a vaporizer, are treated in a leading catalysing unit and the resultant light products separated in a dephlegmator, the oils being then led to a second vaporizer-catalyser-dephlegmator group followed in series by other like groups; the catalysts thusact with increasing durations of activity on masses more and more reduced but increasingly difficult to crack. Two series of the groups may be arranged in a closed circuit to permit regeneration of the catalyst in one series whilst the other series is in operation. As shown, six groups are arranged in cyclic order, the oil main G supplying directly any desired one of the vaporizers V1 - - V6 which are connected through catalyser units T1 - - T6 to dephlegmators D1 - - D6 adapted to discharge the light products through outlets L1 - - L6 and to pass the oils &c. through pipes M1 - - M6 either to the adjacent vaporizer through cocks d1 - - d6 or out of the apparatus through cocks d<1>1 - - d<1>6. Thus, during regeneration of the catalyser in the unit T6, cocks v2 - - v6 leading to the vaporizers V2 - - V6 are closed and oil flows through the cock v to the vaporizer V1. The cocks d5 - - do, and d<1>1 - - d<1>4 are closed and the cocks d1 - - d4 open to direct the oils successively through the first five groups. When the activity of the catalyst in the unit T, ceases, as shown by the absence of products discharged through the outlet L1, the cocks v1, d1 and d<1>5 are closed and the cocks v2, d5, and d<1>6, are opened to direct the oils through the groups V2 - - V6.
