Title: Improvements in corona testing of insulated electrical cables
IPC: G01R31/02
Filed: 1963-09-02
Abstract: 991, 686. Fault testing. OKONITE CO. Sept. 2, 1963 [Oct. 16, 1962], No. 34544/63. Heading G1U. [Also in Division G5] A method of locating defects in the insulation of an insulated electric cable comprises passing the cable through gas ionized with alpha radiation in an insulating tube, maintaining an A.C. voltage between the centre of the tube and its ends whereby an insulation defect can result in corona, detecting corona impulses outside the tube between the centre and the exit end of the tube, and using the impulses to cause the location of the defect to be marked on the insulation. In the Figure electrodes 5, 6 and 10 are mounted within the tube 1 and are coated with polonium P which emits alpha particles and ionizes the air or other gas in the tube. Electrodes 5 and 6 are earthed and electrode 10 connected to a high voltage transformer 12. A pick-up ring 32 detects discharges and records corresponding pulses on magnetic drum 36. A second ring 28 is located at a point corresponding to the required test voltage and if it detects a corona disables an erase head 48 which normally erases signals recorded by ring 32. The cable 2 and drum 36 are driven at related speeds by common driving means so that a spurious signal (not due to corona) recorded by head 44 is normally erased by head 48. True corona signals are passed by head 48 and read by head 52 which causes marking means 56 to make a physical indication on the surface of the cable of the location of a defect. By employing a plurality of rings 28 spaced longitudinally of the tube, each for a different voltage, several corona tests for as many different voltages as there are pick-up rings can be run simultaneously, the head 44 then recording on a plurality of channels on the drum 36. Probe elements similar to 28 and 32 may be placed between electrodes 5 and 10. Specification 878,354 is referred to.

Title: Improvements in or relating to electromagnetic wave guides
IPC: H01P1/22
Filed: 1947-12-30
Abstract: 640,057. Electric attenuators. ROSENBERG, W., and BUCKINGHAM, J. Dec. 30, 1947, No. 34563. [Class 40 (viii)] A wave-guide attenliator or load comprises a disc 1 of lossy material, such as dust iron, protruding through a slot in the broad face of a wave-guide 4. To prevent overheating of the part within the guide, the disc is rotated at about 1500 r.p.m. on the shaft 2 of an electric motor, and cooling fins 7 are provided. The slot in the wave-guide has tapered ends to prevent mismatching, and is surrounded by a plate 6 of lossy material to absorb energy which leaks out. The attenuating effect may be increased by curving the wave-guide to conform with the periphery of the disc, thus increasing the length of the disc material within the guide (Fig. 4, not shown).

Abstract: 478,456. Indicating proximity of earth or other bodies. MONTU, E. Dec. 18, 1936, No. 34763. Convention date, Jan. 31. [Class 37] [Also in Group XL] An apparatus for detecting aeroplanes and the like comprises two directional pickup aerials T<1>, T<2>, Fig. 1, adapted for continuous rotation about perpendicular axes, each being connected to a separate cathoderay tube c<1>, c<2> having associated control means P<1>, P<2> whereby the screen of the tube is completely scanned by the cathode-ray beam once during each passage of the pick-up through its arc of selective directional reception and the intensity of the beam is varied upon the pick-up being excited by radiation coming from the aeroplane or the like. Such radiation may be emitted by a ground station and reflected from the aeroplanes. The pick-ups are connected to the control electrodes of the cathode-ray tubes by amplifiers A<1>, A2 and the screens are scanned once for each half revolution of the pick-up, the line-scanning directions of the two images which are thrown simultaneously on a screen S<1> by mirrors Z being arranged to be at right-angles. The cathode-ray beams are suppressed except when the pick-ups are directed towards the aeroplanes, so that, on excitation of a pick-up, a narrow band appears on the fluorescent screen and the point of intersection of the two bands on the screen S<1> indicates the position of the aeroplane. Instead of two separate tubes, a single cathode-ray tube can be used having two electron guns and associated control means so arranged that each may scan the same area of the screen, the direction of line-scanning movement of the two rays being perpendicular to one another. Each pick-up aerial may comprise a number of dipoles D<1>, Fig. 2, arranged in a circle at the focus of a connentrating reflector R of parabolic section which also acts as a screen.

Abstract: 780,692. Feeding sheets. WENDT, P. H. and ELDREDGE, K. R. Dec. 8, 1955 [April 29, 1955], No. 35315/55. Class 100(1) Sheet-separators:-Sheets are separated from a stack 10 by means of a rotating drum 12 towards the periphery of which the top sheet is drawn by a stationary suction device 22. The drum 12 comprises three separated discs secured to a shaft 66 driven by a belt 24 fitting within a circumferential groove in the middle disc, and the device 22 is fork-shaped to provide two suction nozzles which are situated between the discs and do not extend beyond the peripheries thereof. Within each nozzle is a rod, such as 80, normally urged by a spring 96 in a cylinder 94 to extend beyond the periphery of the drum to prevent, for a time, the top sheet from contacting the drum when suction is applied to the nozzles; when a solenoid-operated valve 100 is automatically opened, compressedair enters the cylinder 94 to withdraw the rod 80 and allow the sheet to be carried by the drum 12. Compressed-air from a box 18 is blown down on to the pile to float the top sheet and assist separation thereof. Separation of more than one sheet at a time is prevented by a device 20 comprising a suction box 110 which applies suction beneath the top lifted sheet. The suction opening in this box 110 cannot be obturated by a sheet since two pusherplates such as 116, which are normally .held against the front face of the box, are pushed against the stack 10 to jog it a slight distance away from the box. Each plate is secured to a rod, such as 120, urged towards the box by a spring in a cylinder 124, and pushed towards the stack when a solenoid 126 opens a valve to allow compressed-air to enter the cylinder 124. As shown, the sheets are stacked vertically, and the stack is bumped up and down by two vibrator belts and a rotating belt. The apparatus includes motor-driven vacuum and compressed-air pumps. Sheet-forwarders:-The belt 24 is pressed against a second belt 28 by a system of drums 26, 32 and rollers, and the sheets are carried by the drum 12 into the bight of the belts which then convey them to a processing apparatus.
