Abstract: A plastic carrier for carrying a plurality of containers, such as cans, bottles and the like, includes a novel structure which maintains a straight grip portion when containers are applied thereto. The carrier includes container engaging portions which are joined to a handle portion by a welded seam. Each container engaging portion includes bands which define apertures therein for holding the containers therein. The handle portion extends generally perpendicular to the container engaging portions when the carrier is applied to the containers. The apertures within each container engaging portion include an inner aperture and a pair of end apertures therein. Each inner and outer aperture is defined by a length measured parallel with the welded seam wherein each inner aperture is substantially shorter than each end aperture.

Abstract: A radiation-shielding storage/transport container has a cast-iron vessel having an open end defining an end face, a steel ring engaging the end face and forming at least one annular seat, a weld unitarily bonding the ring to the end face, and a cover secured to the steel ring in the seat thereof. The cast-iron vessel is formed at its open end with an annular seat having a shoulder surface forming the end face. The weld is an aluminothermic weld that extends over the entire surface of the interface between the ring and the vessel. The ring is formed with two such seats and the cover includes an inner plug cover and an outer cover each in a respective one of the seats. The outer cover is of steel and a second peripheral weld connects the outer cover to the respective seat.

Abstract: A weldment, such as the wall of a pressure vessel, is formed from segments, each of which includes a steel substrate, a protective layer of tantalum which is exposed to the interior of the vessel and an intervening layer of copper which lies between and is bonded to the substrate and the protective layer. The substrate and the two layers which form the cladding are explosively bonded together and the bonding procedure may leave the protective layer with small domes or embossments and pockets of trapped gas behind the embossments. The two segments are welded together edge-to-edge at their substrates, with their protective and intervening layers aligned. If one were to follow the traditional procedure, one would place a tantalum batten strip over the protective layers along the opposed edges so as to cover the edges, and then weld the batten strip to the protective layer along the edges of the strip.

Abstract: A container for a radioactive material in which the cover is welded to the container by a dual weld disposed in a welding gap between the cover and the container wall, the gap having a bottom formed by opposed flanges on the cover and the wall.

The container is mounted on a rotating platform to move the weld area past the welder and the test devices which are fixed when in working position.

Abstract: The invention deals with the butt-welded connection between the endwall and the body of a thermoplastic container. Contrary to the known connection the invention provides the endwall with an axially extending edge, which may form part of a gripping edge and which overlaps the weld, so that the weld beads are hidden, while further the area of transition between the endwall and its edge above the weld has an axial thickness which is in essence the same as the thickness of the endwall and the radial thickness of the axially extending edge of the endwall, so that the material flow of the plastic during molding of the endwall is more even.

Abstract: A container for intermodal transportation of goods is disclosed which has a floor, a roof, and includes side walls having a plurality of vertically oriented stacking frame posts joining a floor-level lower stacking engagement fitting and a roof-level upper stacking engagement fitting. At least one post in each side wall has an inner post member and an outer post member fixed to each other to form a generally box-shaped structure. A reinforcement plate is situated adjacent the floor-level lower stacking engagement fitting and fixed within the box-shaped structure to the inner post member. A notch in each inner post member adjacent the lower stacking engagement fitting exposes an inner surface of the reinforcement plate to permit the insertion of a weld joining the reinforcement plate inner surface to the engagement fitting. An angle member is received within the notch and extends onto the engagement fitting.

A ledge secured to and protruding from the bottom plane of the upper lip. The ledge is located close to the inner portion of the groove.

Abstract: A hermetically sealed housing for a solid state device or the like includes a metal header having a mounting surface and a metal cap mounted on the header and over the mounting surface. The cap includes a cup-shaped portion and a flange extending radially outwardly from the rim of the cup-shaped portion. A weld ring projects from a surface of the flange toward the header mounting surface and is welded to the mounting surface. A second ring projects from the surface of the flange and is spaced radially inwardly from the weld ring. The second ring is shorter than the weld ring so that it preferably just contacts the mounting surface of the header. The second ring captures any metal particles splashed from the weld ring during the welding of the cap to the header and thereby minimizes particle induced noise.

Abstract: A crucible for containing molten magnesium, and a process for forming the crucible. The crucible is formed from ferritic stainless steel, and particularly type 444 stainless steel plate. The method involves forming ferritic stainless steel plate into component parts of the crucible, while maintaining the ferritic stainless steel plate at temperatures above about 200.degree. F. but below the "blue brittle" temperature range. Further, the method involves special techniques for welding the crucible parts. Specifically, the crucible parts are preheated to a temperature of 100.degree.-150.degree. C. and are completely welded by a process utilizing multiple welding passes with a special metal inert gas shielded welding technique before any cool down of the crucible parts below 100.degree. C. is allowed. The welds extend completely through the crucible walls, which are the thickness of steel plate, and completely incorporate the crucible parts while being essentially free of cracks.
