Abstract: In the vertical corner transition arrangement for semi-membrane tanks disclosed in the specification, curved horizontal sides plate of a semi-membrane tank wall are welded to one side of a vertical extruded aluminum modified I-beam with a vertical tapered stiffening corner block projection on the opposite side of the extruded aluminum I-beam, and the edge of a vertical unstiffened curved cylinder section is butt-welded to the projecting edge of the vertical tapered stiffening corner block. The curved plates of an orthogonally oriented semi-membrane tank wall are welded to one side of another vertical extruded I-beam member having a projecting vertical tapered stiffening corner block welded to the opposite side with a projecting edge which is welded to the opposite edge of the vertical stiffened curved cylinder section to complete the corner of the tank.

Abstract: A unitary, four-side container having a bottom is formed from two smaller container units each of which originally has a bottom and four upstanding sides. A corresponding side of each of the smaller units is removed from the level of the associated bottom to form two half units and the two half units then are positioned adjacent one another so that their bottoms and corresponding side walls confront and abut one another. Anchor bolts secure the two half units to one another along and beneath their bottoms and along their abutting side walls. An uncured, curable adhesive polymer is applied to the junctures of the bottoms and side walls and cured to provide a bond between the bottoms and side walls of the half units and between the anchor bolts and the half units.

Abstract: A liquid storage tank can be manufactured with improved efficiency and greater strength by creating bent sheets to form the sides and bottom portions of the tank. The interior corner of the bend is reinforced by an extrusion weld. Two or more of the side/bottom bent sections are then butt jointed together to form a rectangular, t-shaped, or other shaped tank. The tank is completed by two end pieces extrusion welded to the bent side/bottom pieces and a lid extrusion welded to the sides.

Abstract: A sleeve pack to be used with a pallet base and cover to form a container for shipping bulk goods comprises four vertical walls arranged such that each vertical wall is orthogonal to two adjacent walls. At least one vertical wall of corrugated plastic is joined by an edge-to-edge butt welded seam. In a preferred embodiment of the present invention a vertical wall panel having vertically oriented corrugations is edge-to-edge butt welded with a corner piece of corrugated plastic having horizontally oriented corrugations to form a continuous one ply sleeve pack. An alternative embodiment of the present invention is a double thickness, corrugated plastic sleeve pack in which one thickness has horizontal corrugations for side impact resistance and the other thickness has vertically oriented corrugations for increased stacking strength but with all seams butt welded.

Abstract: A container complying with ANSI.RTM. N14.1 for containing uranium hexafluoride (UF.sub.6) which minimizes entrapment of contaminants, thereby increasing the decontaminability of the container. The container includes a cylindrical shell welded to two cylinder heads wherein the weld inside the container provides a smooth transition between the heads and the shell while complying with ANSI.RTM. N14.1. The heads and the shell each have an annular land. A plasma weld fully penetrates the opposing lands to join the heads and the shell. No backup bar is used during the welding process.

Abstract: A container constituted of injection-molded plastic components, the components having the property of enabling discrete particles thereof to be securely joined to each other under the action of heat and pressure. The injection-molded components form a pair of continuous mating edges adapted to constitute a common continuous joint in the container. The edges initially have configurations enabling them to be mutually abutted, and the edges after being so abutted having been subjected to heat and pressure of a magnitude sufficient to cause them to meet and merge into each other to form the continuous joint.

Abstract: A flangeless fuel tank formed of two interfitted cup-shaped tank halves welded along the overlapping portion of the tank halves. Locating protrusions stamped into each tank half provide registration of the halves prior to welding. Spacing dimples stamped into at least one of the fuel tank halves provide a vent space for escaping gases from vaporized coatings.

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: An improved chemical pressure vessel for storage, shipping and pressurized dispensing of fluid chemicals is formed with a seamless fluoropolymer inner liner permanently encapsulated within a metallic overpack. To protect the liner from the heat of welding during encapsulation of the overpack around the liner, the liner is formed with recessed indentation immediately adjacent the weld area. The indentation retains a sacrificial layer of fluoropolymer to ensure that the heat of welding will not affect the liner itself. In addition, the overpack is formed with a protective flange or "puddle plate" in the area of the weld to ensure that there is adequate isolation of the weld puddle from the fluoropolymer liner. The fact that the liner is seamless and permanently encapsulated within the overpack eliminates the need for periodic disassembly of the vessel for inspection of seams for possible leakage.
