Abstract

413,364. Discharge apparatus. BANCROFT, F. E., 19, Delaine Road, Withing- ton, SMETHURST, H., 147, Victoria Road, Fallowfield, both in Manchester, BURROWS, G., Lynton, Fownhope Avenue, Sale, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Jan. 19, 1933, No. 1815. [Class 39 (i).] In a vacuum seal, suitable for vacuum furnaces, large thermionic valves, vacuum condensers, vacuum vapour traps, vacuum circuit breakers, &c., which can be rapidly dismantled and remade, a ridge or flange having a plane end face on one part such as the cylinder 1 enters a groove or channel 6 which is slightly wider in the other part, e.g. the cover 2, and a thin gasket of solid, compressible, non-absorbent material such as lead 7 or a composition of granulated cork leather, &c., is placed between them. The seal is completed by a low-vapour pressure oil such as that known under the Registered Trade Mark "Apiezon" which floods the atmospheric side of the gasket and is housed in a separate reservoir channel. The groove 6 is undercut at 8, the reservoir channel 10 is formed by a cylindrical flange 9 secured to a flange 5 to which the cover is bolted. By means of pins 12 and inclines on the flange 9 a displacer ring 11 is raised or removed before breaking the joint to prevent oil running into the container. The ring 11 may be replaced by a downwardly-extending flange around the cover 2. The cylinder has an interior flange 14 with an oil-trap groove 15 which flange protects the vacuum seal against electron or other bombardment and the effects of radiant heat. The cover 2 is cooled by a jacket 16. In a modification, applicable to a bottom cover, a flange on the cylinder enters a recess in the cover. The oil channel is connected to a pipe with a cup and a drain cock which enables it to be filled and emptied. A hole in the door is provided with a screw plug similarly packed. In a further construction, two similar channels engaged by flanges of different diameters with a liquid seal between, are provided. Cooling fluid is supplied to a device such as an X-ray tube, by concentric tubes carried by the cover. Specification 346,293, [Group XXXVIII], is referred to.
