Title: Improvements relating to the corona-testing of the insulation of electric wires and cables
IPC: G01R31/02
Filed: 1958-11-13
Abstract: 878,354. Testing cable insulation. OKONITE CO. Nov. 13, 1958 [Nov. 25, 1957], No. 36526/58. Class 37. In apparatus for the corona-testing of electrical insulation the insulation is stressed by a high voltage to ionize any deleterious gas which may be occluded in the insulation so as to cause corona to be formed at that place, the presence of corona formation being marked at a predetermined position relative to the site of the occlusion. The Figure shows an apparatus for the electrical testing of the insulation of an electrical cable 10 which is fed from a reel 11 on to a take-up reel 17 at which point the central conductor of the cable is earthed at 18. In its passage between the reels the cable passes through a tank 12, a tube 14 of insulating material and a tank 16 all of which are filled with a liquid of relatively low conductivity, for example distilled water. The tanks 12, 16 are earthed and a high voltage is applied to an electrode 22 situated at the central part of the tube 14 and derived from high-voltage transformer 24 so that a high electrical stress is applied between the cable insulation and its central conductor which increases as the cable moves towards the electrode 22. The value of the high voltage from transformer 24 is set so that at some point along its travel a corona discharge occurs in the insulation. If this is persisting as the cable passes through a pick-up ring 32 it actuates a pulse generator 42 via amplifier 34 and causes a record 46 to be placed on a magnetic recording medium 36 which is driven via units 38, 40 at a speed bearing a constant ratio to that at which the cable is advanced. If the indication of corona at pick-up ring 32 is due to an interfering unwanted signal then as the cable passes through a further pick-up ring 28 a signal is produced to erase the record from the recording medium. If, however, corona persists in the cable, i.e. not due to an interfering phenomena, the erase head 48 will not be energized and the record will be maintained on the medium 36. When the record is read at head 52 it activates a marking device 56 which, for example, sprays the cable insulation at that point, which may be at the site of the occlusion or at some predetermined distance from it. The record on the recording medium may be finally erased by head 58. A multi-track record may be produced at predetermined values of stress voltage.

Abstract: 921,784. Electric bells. WALTER KIDDE CO. Ltd. Jan. 30, 1961 [Oct. 28, 1959], No. 36537/59. Class 13. Impacts of an electromagnetically-operated striker, such as an arm 32 rotated by an electric motor, are communicated through a wall 15, either directly or by way of a resiliently mounted bolt 13, to a hammer 12 which is thereby caused to strike a gong 11. The wall 15 may divide a compartment 10, which is liable to contain an explosive mixture, from another compartment 31 which is free from such a mixture.

Abstract: 1429365 Automatic control of temperature NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR STATE DEFENCE 1 Aug 1973 [2 Aug 1972] 36603/73 Heading G3R [Also in Division G1] The heat absorbed or emitted by a sample 3 at a given temperature in an endothermic or exothermic reaction is determined by a calorimeter comprising a heat flowmeter 4 on which the sample 3 rests in a cavity 2 defined by housing 1, a heat insulating layer 7 surrounding the housing which is itself surrounded by a heater 6, and means arranged automatically to control the heater 6 in response to the temperature difference between the inner and outer surfaces of the layer 7 to minimize the flow of heat therethrough. As described, the housing 1 may be enclosed in a series of insulating layers 7, 9, 11 having lids 7a, 9a, 1 1a, the layers being separated by electric  heater jackets 6, 8, which are connected in series and independent of a jacket 5 which determines the temperature of the cavity being supplied by a stabilized voltage supply 17. Jackets 6, 8 are actuated when sensors 12, 13 detect a temperature drop across layer 7. After initial calibration using a sample of known heat capacity, the heat flow through meter 4, which may be a Peltier effect meter, due to a sample 3 may be plotted on a recorder 18 for later analysis. The current through jackets 6, 8 may be determined by a variable transformer 15 driven by a motor 16 controlled by a controller 14, probes 12, 13 being connected in an input resistance bridge thereof.

Class 100(2) For a platen printing-machine in which single sheets are fed on to a toggle plate swinging about a horizontal axis, and raised thereby against a more or less upright forme, to which ink is periodically supplied from the surface of a drum, a wash-up device comprises a longitudinally flexible strip of vulcanised fibre or other suitable non-metallic material which is provided at its ends with suspension means enabling it to be supported in a substantially vertical plane with its upper edge somewhat below the axis of the ink drum, a cross-bar adapted to be mounted on the machine in parallel relation to the flexible strip, and individually operable means carried by said cross-bar at longitudinally spaced positions, whereby the upper inner surface of said strip can be forced against said drum with adjustable pressure. The wiper element. 5 comprises a strip of vulcanised fibre or nylon ¥ in. wide, # in. thick and of the same length as the ink drum 6, and is riveted to a flexible steel carrier 8 supported by links 10 from the machine frames 11 at pins 15 resting in slots 12 receiving the bearings of distributing-rollers 14. A cross-bar 19 is mounted between the frames 11 about 4¢ in. behind the element 5, and is provided with four axially spaced bores 20, each receiving a thumb-screw 21, whose projecting shank carries an internally threaded nosepiece 22. The carrier 8 is held against the nosepieces 22 by tension springs 24. The nosepieces are adjusted until the element 5 engages the drum 6 with uniform pressure along its length. Riveted to the carrier 8 is a metal plate 27 whose lower edge is shaped to form gutters 28 converging to an offset lip 29, over which the ink sludge, removed by the wiper element and flowing over the carrier 8, is directed into a detachable tray 30. The screws 21 are of such a length as to be unable to contact the drum 6, even if the wiper element is not in position, while on full retraction of the screws, a clearance of # inch is obtained between the drum and the wiper element.

When the lugs 22 are aligned with the recesses in the upper edges of the lugs 25 the latter spring upwardly with the bias of the fingers to engage the recesses around the lugs 22. To remove the cap it must first be depressed against the bias of the fingers 29 and then rotated. In modifications the lugs 22 may be formed on a detachable plastics ring, may be bounded on all sides by the rolled edge 14 or may merely be formed by deforming the edge rather than piercing it. In one form the lugs 22, 25 may take the form of co-operating teeth (see Specification 1,104,001). The cap may have an outer depending cylindrical wall to engage the rolled edge 11 with the co-operating lugs being formed on the edge 11 and the outer wall, in which case the resilient fingers 29 can engage top wall part 12. The position of the lugs 22, 25 can be reversed.

The spout 14 has a part-cylindrical knuckle 44 allowing its rotation to align a bore 50 with the hole 24. The lower sides 52 of the trunnions 40 are made flat, to facilitate their insertion through the tapered slots 34, 36. In the form shown, the top of the spout 14 when in its closed position lies flush with the top of the cap body 12. Alternatively the spout 14, trunnions, &c. may be arranged partly above the top of the cap body 12.

The filter cake from step (d) can be slurried in additional solvent and then filtered at 47 to separate de-oiled wax and a filtrate 52 which is used to further cool the high pressure refrigerant from step (e) by indirect heat exchange. The process is used to separate wax from mineral oils, such as a solvent refined vacuum distillate, and is stated to be useful for the separation of waxes from animal or vege-. table oils. Suitable dewaxing solvents are methyl ethyl ketone, methyl isopropyl ketone and methyl isobutyl ketone and can contain benzene or toluene. The refrigerant can be ethane, ethylene, propane, butene, dichloromethane, difluoromethane or ammonia.
