Title: Insulation of high tension conductors in electrical precipitators
IPC: H01B3/28
Filed: 1934-05-25
Abstract: To prevent current leakage in an electrical precipitator for cleaning gases and vapours, due to condensation on the insulator for supporting the high tension conductor, the surface of the insulator is formed wholly or partly of a composition consisting substantially of solid chlorinated naphthalene, but which may contain up to 20 per cent by weight of stiffening material such as chlorinated rubber and polymerized benzyl chloride.  As shown in Fig. 1 the discharge electrode of a precipitator is supported by a silica dome 1 the rim of which is embedded in chlornaph <PICT:0438807/III/1> <PICT:0438807/III/2> thalene 2 contained in an annular trough 3.  The upper surface of the chlornaphthalene slopes away from the dome so that moisture collecting on this surface drains away.  The dome may be completely coated with chlornaphthalene, or the inner surface of the dome may be provided with a continuous belt of this material. In the modified construction shown in Fig. 2 the electrode support 5 is carried by a dome-shaped structure 8 which is formed of chlornaphthalene and reinforced by metallic members 3, 4.  The structure 8 either rests upon or is embedded in chlorinated naphthalene 2 contained in a tray 3 which is mounted at the top of the precipitating chamber 1.  The electrode support 5 has baffles 6 formed of or coated with chlorinated naphthalene.

Abstract: 704,405. Treating liquids with gases. A.P.V. CO., Ltd. July 1, 1952 [July 11, 1951], No. 16490/51. Class 55 (2) In a distillation column having superposed, perforated bubbling plates, each plate has a seal trough into which the downcomer from the plate above dips and is thereby sealed, the liquid supplied from the downcomer overflowing from the seal trough into a number of outwardly extend; ing, open transfer troughs which carry it to an outer distribution trough whence it is directed inwardly over the perforated plate area to the downcomer duct leading to the plate below. The Figure shows two sectional elevations taken at right angles to each other of a cylindrical distillation column 1 having inlets 28 and an outlet 29 for vapour and inlets 26 and an outlet 27 for liquid and containing six bubbling plates, each comprising a diametrically positioned seal trough 2 which receives liquid from an elongated downcomer duct 3. The liquid collects in trough 2 and seals the downcomer and then overflows'into two sets of open-topped transfer troughs 4 which carry it to a peripheral distribution trough 5 whence it overflows on to perforated plates 8. It then flows inwardly over these plates and is subjected to the bubbling action of the vapour and passes into the next 'downcomer duct 3. The vapour rises from the space below the plate through gaps left between channel section floor plates 9 and is deflected by hoods 11 to the underside of the plates 8 whence it bubbles up through the liquid flowing across the plates.
