Title: Improvements in the manufacture of electric cables
IPC: H01B13/30
Filed: 1941-11-06
Abstract: 553,145. Electric. cables. CALLENDER'S CABLE & CONSTRUCTION CO., Ltd., and VINCENT, R. S. Nov. 6, 1941, No. 14322. Class 36] In making an electric cable insulated with impregnated paper the impregnant is filtered before entering the paper by forcing it inwardly through a porous envelope surrounding the insulated conductor or conductors, and the whole or outer part of the porous envelope is then removed and replaced by a liquid-impervious envelope such as a lead sheath. In Fig. 1, a  stranded conductor 1 is surrounded by layers of helically-wrapped paper tape 2, a screen 3 comprising a tapping of perforated metallized paper tape, and a helical wrapping 4 of fabric tape into which Cti wires are woven; a filter layer 5, comprising paper loaded with filter clay such as Fuller's earth or kaolin is then applied and the end of the cable is sealed off as by continuing the filtering layer over the end or by a tinned Cu cylinder 6 held by a loaded paper wrapping 7 and wire binding 8. In a multi-core cable, each core may be provided with the layers 2, 3, the cores laid up with padding, and the layers 4, 5 wound round the whole, or the layer 3 may be omitted and the layer 4 replaced by wrapped paper belt insulation. Instead of loaded paper, the filter layer 5 may be formed of strip material, such as paper, coated on one side or both sides with the filter material before or during the lapping process or both, or of composite strip comprising a pair of paper &c. tapes 16, Fig. 8, spaced by narrow marginal tapes 17 within which the filtering material is sandwiched, the composite strip being formed as by feeding the tapes 16, 17 down between two horizontal rolls fed with, or immersed in, the filter medium in powder form, or mixed with water, a non-aqueous volatile liquid, or impregnating oil. The boundary between the dielectric and the filter layer may be indicated by layer of blue &c. paper tape which is left on until the cable is to be sheathed. One or more layers of plain paper tape may be placed over the filter layer. After applying the filter layer, air and moisture are removed by a vacuum process which also draws impregnant through the filter layer into the dielectric; this process may be assisted by use of an end cap 6 modified to allow the conductor 1 to be connected to the evacuation plant. Some or all the filter layer is then removed and the sheath is applied: In multi;core cables with separately sheathed cores, each core is treated alone as above.

Abstract: 805,415. Filters. FRAM CORPORATION. May 6, 1957, No. 14341/57. Class 46. Hydrocarbon liquid, containing a small proportion of water, introduced at 17, Fig. 2, discharges over the top of a riser 19 into an upper (high pressure) chamber and passes through a number of coalescer cartridges 26, each consisting of perforated cylinders 29, 37, Fig. 4, enclosing between them a fibre glass tube 27 having longitudinal grooves 28. The water in the mixture is coalesced by the tubes 27 and the mixture passes down into sacks 39, each having a wired hem cemented to and pressed (by the end of cylinder 37) against the bottom of a threaded sleeve 35 formed on the lower end plate 32 and screwed into a hole 35a in a partition 23. Hydrocarbon liquid passes through the sacks into the lower chamber (at lower pressure) while water collects therein until its weight reaches a critical value, whereupon it passes through the interstices of the fabric intd the water pool W maintained automatically at the level shown. The hydrocarbon liquid is discharged from the upper end of a riser 20 within a domed part 24 of the partition 23 so that separation is assisted by gravity. Specification 777,320 is referred to.

Abstract: 473,779. Switchgear structures. GENERAL ELECTRIC CO., Ltd., and ANDERSON, A. M. May 28, 1936, No. 15115. [Class 38 (v)] The tank of a vertically-withdrawable oilswitch is adapted to support the switch in a relative position such that the main contacts of the switch are accessible, and the tank and switch are removable together from the fixed parts of the switchgear. The drawing shows the tank lowered from the switch and both removed from the fixed part of the gear. The tank 1 is normally secured to the top plate 10 by means of four spindles 11 on the latter extending through lugs 14 and brackets 16, and threaded at their lower ends to receive nuts 15. The lowering gear for the unit comprises, at each side, a threaded spindle 17 with a nut 18 having a part 19 adapted to engage a boss 20 on the tank, the spindles being operated together by handle 21. When the tank is to be lowered for inspection of contacts 2, '3, the unit is lowered to isolating position in which the plate 10 rests on removable support bars (not shown). After removing nuts 15, the tank is further lowered until brackets 16 pass below the spindles 11, whereupon nuts 15 are replaced. The tank is further lowered until lugs 14 engage the nuts 15, whereupon slotted collars 12 are inserted in annular grooves on the spindles just above the lugs 14, the nuts being then tightened to clamp the lugs against the collars 12. The unit is then slightly raised to remove the support bars and then lowered on to wheels 13, and after removing parts 19 from bosses 20, the unit can be wheeled away. The unit may be lowered direct to ground, if desired.
