Abstract

1444256 Sealing containers by welding; extruding SKF INDUSTRIAL TRADING & DEVELOPMENT CO BV 22 June 1973 [26 June 1972] 29747/73 Headings B3R and B3P [Also in Division B5] In a method of sealing material in a container at a pressure less than 10<SP>-1</SP> torr, the container 4a, Fig. 1, or a portion thereof is filled with the material 6 supplied through the open top of the container, the top layer of the material which may be the same or a different substance from that of the remainder of the material being fusible. The container is located, with the material therein, in a chamber 1, the pressure within the chamber is reduced to less than 10<SP>-1</SP> torr and, the top layer of the is fused to the wall of the container after which it solidifies to form a seal welded to the wall and cooperating therewith to enclose totally the remainder of the material. The material may be in powder, granular or tablet form, in which latter case the top tablet, is partly or wholly fused to the wall. In other examples the top layer may have the same composition as the wall, which may be of metal or plastics, e.g. P.V.C. In Fig. 1, electron beam welding is used to fuse the material, the welding device including the vacuum chamber 1. The containers are transported on interconnected conveyer belts 3a-3c and a vibrating device 5 compacts the powder material. Means for maintaining the material in the container 4b during welding may be as shown, electromagnetic coils 10, if the material is magnetizable. In Fig. 5, rotating friction welding discs 36a, 36b are alternatively used to weld both ends of the container 39 simultaneously. The sealed containers produced are said to be particularly suitable for extrusion into bars or tubes of round or other section.
