Abstract: A process for producing sheet-metal jackets, especially for pallet containers with an inner container of a synthetic resin, wherein a rectangular cut-to-size sheet-metal blank, the narrow sides of which are folded over into rims, is bent into a tubular member (15), and the rims (11a, 12a) of the tubular member (15) are hooked together. From the interlocked rims (11a, 12a), a series of spaced-apart connecting straps (16) is shaped by cutting and embossing toward the outside in a series parallel to the rims (11a, 12a) while leaving undeformed the rims between the spaced-apart portions. The rims (11a, 12a) are locked with respect to each other by a wire (17) pulled through the connecting straps (16), and the thusproduced tubular member (15) is shaped on a stretching press into a sheet-metal jacket.

The stacking surface (8) of the lid portion (4) passes over into two webs (17, 18) extending in the circumferential direction and encompassing the bottom surface of the depression (11) for the filling and discharge bunghole (9), these webs running with a slight slope from the stacking surface (8) toward the bottom surface of the depression (11) and forming, in the slightly tilted upended position (1') of the bunghole barrel, drainage channels (21, 22) for the residual fluid (24) collecting on the inside (27) of the lid portion (4) and flowing off through the bunghole opening (15) of the filling and discharge bunghole (9).

Abstract: A process for the production of tighthead drums having dimensional stability of the injection molded lids and blow molded drum bodies, comprises blow molding double drum bodies from plastic and centrally separating them into two drum bodies. Tighthead lids are produced by injection molding from plastic. The tighthead lids are then welded to the drum bodies. Widemouth drums are also produced by blow molding double drum bodies from plastic and centrally separating them into two drum bodies, but with a molded-on edge at a distance under the drum opening. Drum lids are injected molded from plastic with an outside flange molded-on the lower lid edge. A sealant of plastic is injected into the lids and the lids are positioned on the drum bodies sealed with a clamping ring.

Abstract: The pallet container comprises a wooden pallet or a steel pipe pallet, on which is mounted an inner container of a synthetic resin with a jacket of vertical and horizontal lattice bars (4, 5) of steel pipe, these bars forming continuous inner and outer tangential planes; (20-20, 25-25). At the points of intersection (15), the lattice bars are drawn in to form trough-like indentations. This configuration has the result that, at each point of intersection (15), four contact points (22) disposed in one plane (21-21) are produced with an accumulation of material in each case corresponding to four times the wall thickness of the lattice bars. The lattice bars (4, 5) are joined together at the points of intersection (15) in the zone of the contact points (22) by electric resistance welding. The pallet container is usable as a safely operating multiple-trip container for liquid merchandise of all kinds.

Abstract: Wishbone boom mounting for sailboards with a wishbone head section of a synthetic resin, integrally molded onto a curved pipe section of aluminum or synthetic resin for attaching the two spars of a wishbone boom, and a jacket section accommodating the curved pipe section. A collar is connected to the jacket section by at least one web and is placeable on the mast. A locking element is articulated to this collar and receives the mast. A quick-action closure closes and opens the locking element in order to mount the head section to the mast or to detach the head section from the mast. A hinged cover (10) is molded onto the collar (6) of the wishbone head section (1) by a thin flexible hinge (11) and is curved to match the mast (5). A clamping lever (12) is articulated to the collar (6) for tightening and releasing a rope piece (13) forming a loop (14), one end of this rope piece being attached to the clamping lever (12) and the other end to the collar (6) in the region of the thin flexible hinge (11).

Abstract: In a spigoted barrel of a synthetic resin, welded together from two or more parts, with a sidewall section, a head section, and a lid section, exhibiting bungholes (e.g. 9) hidden in depressions, a barrier (13) is integrally molded to the inner surface (12) of each depression (e.g. 11) of the lid section (4), this barrier extending in an arcuate shape from the sidewall section (14) around the respective bunghole (9) and constituting a collecting pan for a residual content (16) of the barrel. Thereby, upon tilting of the barrel, complete emptying becomes possible. The barrier (13) is lower in the zone around the bunghole (9) than in the regions toward the sidewall section (14) so that the barrier (13) does not form a hindrance during cleaning of the barrel.

Abstract: The lip gasket for the daggerboard well of a sailboard (1) exhibits two supporting strips (3) embedded in the board body on both sides of the daggerboard well opening (2), as well as two cover strips (5), terminating with the profile (4) of the underwater hull and designed as clamping strips, for being clamped into the supporting strips (3). The cover strips (5) consist of a flat extruded profile exhibiting an outer clamping zone (6) of a hard synthetic resin, for example polyvinyl chloride, and an inner zone, forming a sealing lip (7), of an elastic synthetic resin, for example polyurethane. The two sealing lips (7) of the lip gasket constitute an elastic, tight seal of the daggerboard well opening (2) in the folded (8') and in the deployed (8") position of the daggerboard (8).

The stringer (5) is integrally molded in double-wall fashion to the upper one and/or the lower one of the half shells (3, 4) with a profile that is U-shaped over at least the largest part of its length, and is welded, along the base of its U-shaped profile, to the respectively opposed half shell (3 or 4). The profile cavity of the stringer (5) is filled with glued-in-place hard foam elements (12) and sealed by profiled strips (14). The foam core (11) consists of a foam composition injected into the cavity defined by the welded-together half shells (3, 4).

Abstract: The wide-necked barrel of a synthetic resin can be sealed by a lid exhibiting a bottom entering into the barrel neck by way of an inner rim, and an outer rim extending over the barrel neck and having a radial lid flange. The lid is sealed by a sealing ring inserted into the annular groove between the inner rim and the outer rim of the lid. The lid flange has on the underside alternatingly tongue-like extensions and recesses arranged with a specific pitch over the circumference of the lid. Annular flange segments integrally molded to the barrel neck engage into the flange recesses and complete the partial cross-sectional profile of the lid flange, formed in the zone of the recesses, to the full cross-sectional profile of the lid flange in the zone of the extensions. The clamping ring encompassing the lid flange and the annular flange segments is secured by means of clamping ridges integrally molded to the lid extensions and extending in the circumferential direction.

Abstract: A composite steel-jacketed plastic barrel has a cylindrical sheet steel shell with a lower sheet steel bottom flanged thereto, and a plastic lining which comprises the upper end of the barrel and has bungholes through that upper end. Both the upper end of the lining and the upper end of the shell have radially outwardly extending flanges thereon; and a detachable clamping ring releasably interconnects these flanges, so that either the steel component or the plastic component can be separately used or replaced. The construction permits saving of the plastic material of the lining, in that the thickness thereof decreases uniformly from top to bottom.
