A keg (10) for a pressurized fluid is formed of a main body part (11), to respective open ends of which are secured upper and lower ends parts (14, 12), each of the three parts being an injection moulding of thermoplastics material and connected together by welding. Around an internal surface of the main body part (11) is an integral continuous planar flange (21) which serves to resits outwards pressure on the body when the keg is pressurized, in use, the flange defining a large central opening (22) in the interior of the keg. Ribs (25) are formed integrally with the internal body surface and flange, and extend around the flange between respective pairs of first openings (23) through the flange, smaller second openings (24) being aligned with, and disposed at the inner end of the respective ribs.

Container for transporting, storing and dispensing chemical products, including an inner shell made of fluoroplastic, particularly PFA, fitted at its upper part with a stopper device traversed by filling and dispensing connections, and an outer shell exhibiting a substantially cylindrical outer shape and an inner shape substantially matching that of the inner shell. The outer shell (1) is made up of a cylindrical part (6) which, at its lower part, is integral with a base (7) of quadrilateral cross-section and of greater cross-sectional area than that of the cylindrical part of the outer shell.

A composite double-wall underground tank comprises an internal rotatable metal mandrel tank frame structure surmounted by two individual concentric corrugated cylindrical nonmetallic pressure vessels having hemispherical ends. The metal tank frame structure provides the buckling resistance and compression strength to resist soil loads when the tank is buried. The pressure vessels are made of identical materials and include an internal primary container enclosed by an external secondary container of equal tensile strength and corrosion-resistance. The composite double-wall underground tank is a substantial improvement over conventional steel and fiberglass tanks, and provides a more reliable method of protecting the environment by preventing the release of contaminating hazardous liquids stored in the tank. Each of the two pressure vessels is made from a multiple ply composite laminate having a unique arrangement of fabrics containing filament reinforcements impregnated with a thermosetting polymeric matrix. The hemispherical ends have sealable axle access openings. The top tank fitting outlets include non-corrugated portions of the cylindrical laminate structures bonded together and sandwiched between bolted metal plates that are structurally connected to the tank frame and sealed with an overlapping laminate structure.

A fluid receptacle is provided with a retainer on the inner surface thereof for confining at least the reactive portion of a coated insert matrix within the receptacle during inversion thereof. The insert has a configuration permitting fluid to be poured into the receptacle and decanted from the receptacle by inversion of the receptacle with the reactive portion of the insert confined therein. The various decanting, washing and measuring operations involved in an assay may therefore be performed while the insert remains confined within the original receptacle, eliminating the need for additional receptacles and for manual assembly or disassembly operations during the assay.

A generator for obtaining radioactive gallium-68 from germanium-68 bound in a resin containing unsubstituted phenolic hydroxyl groups. The germanium-68 is loaded into the resin from an aqueous solution of the germanium-68. A physiologically acceptable solution of gallium-68 having an activity of 0.1 to 50 millicuries per milliliter of gallium-68 solution is obtained. The solution is obtained from the bound germanium-68 which forms gallium-68 in situ by eluting the column with a hydrochloric acid solution to form an acidic solution of gallium-68. The acidic solution of gallium-68 can be neutralized.

A liquid transport container unit carried by a vehicle for transporting liquid products such as water or gasoline is disclosed, such unit utilizing an elongated base section positioned parallel to the direction of movement of the vehicle. This base section contains an internal chamber for containing the liquid to be transported. An elongated upper section positioned substantially parallel to the base section is also mounted to the vehicle. This upper section is elevated with respect to the base section and also has an internal chamber for receiving the liquid. A plurality of return portions are connected between the base section and the upper section and are adapted for communicating the liquid between the internal chambers of the upper and base sections.

A cabinet for enclosing a water softener system, which system includes a free standing resin tank, has a cylindrical brine tank side wall member, mounted on top of a horizontal cabinet base and forming a brine tank therewith. An integrally formed cabinet side wall member having a vertical front wall portion and a pair of vertical side wall portions extending rearwardly from the front wall portion is mounted on top of the base. The cabinet side wall member surrounds the brine tank on at least three sides of the brine tank and the side wall portion extends rearwardly beyond the brine tank by a distance sufficient to enclose substantially on at least three sides the free standing resin tank. A brine tank cover is mounted on top of the cabinet side wall member and defines an opening therein through which salt may be added to the brine tank.

A furniture component system comprises connecting members each having a pair of mutually angularly divergent limbs, and plate-shaped members having at least one edge formed with at least two holes extending inwardly of the respective plate-shaped member, each of the holes being dimensioned to receive therein one of the connecting member limbs, whereby the plate-shaped members are connectible together in mutually angularly disposed relationship, whereby relative movement apart of a connected pair of the plate-shaped members may be restricted to one direction only. Preferably, the plate-shaped members are rectangular and the connecting members are L-shaped. The system can be assembled to form boxes, cupboards, shelves, tables and other articles of furniture.

A stackable loading platform having a bottom with a plurality of feet. A plurality of supports are respectively located at the feet and are detachably arranged therein. A plurality of side walls are arranged between and detachably engage the respective adjacent supports. The side walls, in the corner regions of their upper edges, are positively connected to the supports. The supports are selectively movable in the longitudinal direction thereof away from the bottom for removing the supports from the platform. In the region of the feet, rigid stops are associated with the platform for securing the lower portion of the side walls against inward movements.

A tool box constructed of sheetlike metal includes a lower compartment which is the major containing part and within which the tools and other materials are received, and a cover which pivotally is received thereon. The upper edges of the lower compartment are formed into a rolled edge which both adds strength to the wall and provides safety against accidental cutting or other injury to the user. In fabrication, the lower compartment is formed from two sheetlike members, the first member having what will be its upper edges rolled into a generally cylindrical form and then the member is shaped to provide a front panel and two end panels. The second member is formed by bending a rectangular sheet into an L-shape, providing the bottom and rear walls for the containing part of the chest. The rear wall of the lower chamber has its upper edge rolled with a substantial gap provided which is received onto a similarly rolled edge of the cover to provide a pivotal hinge for the cover.
