Abstract
1392683 Welding by fusion D SCIAKY 29 Aug 1973 [16 Feb 1973] 40692/73 Heading B3R [Also in Divisions F2 and H1] Sealing means for a rotary tube 5 or other cylindrical object where it passes through a wall 13 of a vacuum chamber, e.g. the welding chamber 2 of an electron beam welding machine, comprises an annular resilient seal 12 divided on a diameter into two separable mating parts and having two sealing surfaces24 on its inner periphery separated by a groove 30, each part having on one of its mating faces a projection 38, substantially the same cross-section as the groove 30, extending radially thereacross and a complementary radial groove on the other mating face whereby, when the parts are assembled, the projection on one part engages the groove in the other. The projection 38 may be integral with its associated part or fixed thereto by an adhesive. The wall 13 is in two sections, the upper being slidable to allow access to the chamber interior. In the described machine, the chamber 2 houses four tube ends and the seals for the four tubes are moulded in one piece, each tube being sealed by two spaced seals. The upper halves of the seals are carried by a support 19 secured by bolts 20 to the slidable portion of wall 13 and the lower halves are carried by a support 27 secured by bolts 28 to the fixed part of the wall, the outer ends of the seals being held by retainer plates 21 and 29. The space between the seals on each tube is connected by a passageway 23 to a vacuum pump (not shown). Wall 13 is sealed by an 0-ring 26 separable in the plane of the tube axes. Before entering it into the chamber 2 each tube is sealed internally by a plug 32, Fig. 6, comprising an 0-ring 33 compressed between two cylindrical members 34, 36 by screw means 35. The slidable wall portion is lifted by a pneumatic cylinder 15. The tubes 5 are rotated by a motor 8 during welding thereon of parts 6 by electron guns 3 controlled by a mechanism 17.
