Abstract:
A lid (1) is injection-molded of polyethylene, for a widemouthed barrel of a synthetic resin, and includes an outer rim (4) encompassing the barrel neck (3) and an inner rim (5) dipping into the barrel neck. The outer lid rim (4) and inner lid rim (5) form an annular space (7), an annular web (8) projecting axially from the base of this space. For producing the lid gasket (13), the annular space (7) is exposed to an open flame for activating the annular space surface. Subsequently the sealing material, preferably polyurethane, is injected from a foaming machine into the base of the annular space (7), and thereafter the lid (1) is vibrated in order to degasify the gasket (13). The sealing material, preferably consisting of foamed polyurethane, contains a parting compound having a long-term effect.
Abstract:
Tighthead barrel (1) is blow molded from thermoplastic. Top (4) which is arched to the outside has dome shape (9) and with its outside edge (10) at distance (a) under bearing surface (7) of carrying and rolling ring (5) which is pointed perpendicularly or obliquely to barrel axis (6--6) at a steep slant angle runs into top end section (11) of barrel jacket (2). Carrying and rolling ring (5) projects upward in the direction of barrel axis (6--6) above crown (16) of top (4). Arched stacking surface (17) of top (4) passes into two ramp-like deck sections (19, 20), which border deck surface (18) of recess (12) for filler and drain plug (14), which emerge in the peripheral direction of the top, and which run with a slight gradient from central stacking surface (17) of top (4) to deck surface (18) of recess (12) for filler and drain plug (14) and via which in the slightly tilted head position of tighthead barrel (1) the residual liquid which emerges through hole (25) of filler and drain plug (14) and which collects on inside (23) of top (4) drains, ramp-like deck sections (19, 20) being made as bridges and forming gutters (21, 22) which run on outside edge (10) of top (4).
Abstract:
A sheet metal container (1) used as a returnable or nonreturnable container for transport and storage of liquids has a fill neck (3) which can be sealed with a cap (4) and another neck (5) in the bottom area for connecting a discharge and flushing cock, and an external lattice jacket (6) of metal. A pallet (9) is formed as a flat bottom pan (10) from sheet for form-fittingly accommodating the sheet metal container (1) which is equipped with a drainage bottom. The sheet metal container (1) is welded together from a jacket (11), a bottom part (12) and a cover (13). The jacket (11), bottom part (12) and cover (13) of the container (1) are produced with a double wall of composite construction consisting of a thin inner sheet of corrosion-proof special steel and an outer sheet of normal steel with a thickness greater than that of the inner sheet. It is possible to produce the container (1) of clad sheet metal with a thin inner layer of special steel and a thicker outer layer of normal steel.
Abstract:
The top (2) of a sheet metal container (1) for the transportation and storage of liquids has a central fill opening (3) which is edged by a neck (5) which is perpendicular to the top surface (4) of the container. A plastic or metal ring (6) with an external thread (7) is pressed down against the top surface (4) by the upper edge (8) of the neck (5). The neck is swaged outwardly. The threaded ring (6) is protected against rotation by form-fit connections on the neck (5). A plastic screw cap (11) into which a disc-shaped insert (12) of special steel is pressed, is screwed onto the threaded ring (6). Between the outside edge (13) of the cap insert (12) and a ring projection (14) of the latter, an annular groove (15) for holding a gasket (16) is molded into the insert, and by this gasket (16) the screw cap (11) is sealed against the upper edge (8) of the neck (5).
Abstract:
A pallet (1) is made of steel or plastic, with a sublime (2), corner feet (7) and center feet (15, 16), a base pan (8) made of sheet metal, resting on feet (7, 15, 16), with a drainage bottom (9), which has a drainage channel (10). Base pan (8) holds, with positive fit, an internal container (11) made of plastic with an outer jacket (12) made of sheet metal or lattice work and a drainage bottom (13), or forms part of a sheet metal container. A stiffening sheet (14), made like a girder, is fastened under the base pan (8), crosswise to its drainage channel (10). Further to provide greater transport security and simplification of construction, two center feet (15, 16) are integrally molded on both ends (14a, 14b) of the stiffening sheet (14) that is made like a bridge.
Abstract:
A process for reconditioning a standardized tight head drum for re-use as either a tight-head drum or a wide-neck drum. The standardized tight head drum has an upper head drum welded to the drum body at a seam. This drum is reconditioned by separating the upper drum head from the drum along a cut line at a location below the seam. The cut edge is smoothed and sized and the interior of the drum is cleaned. For re-use as a tight head drum, an upper head having a fill plug and a vent plug is welded onto the cut edge of the drum. For re-use as a wide-neck drum, a neck ring is welded onto the cut edge and a wide-neck drum cover is placed on the neck ring. The reconditioned tight head and wide-neck drums have the same nominal volume and the same height and diameter dimensions as the tight head drum prior to reconditioning.
Abstract:
A pallet container (1), which is used as a single-use or multi-use container for the transport and storage of liquids of various types, has an outer jacket (2) made of criss-crossing vertical and horizontal lattice bars (3, 4) made of metal, a support insert (5), which can be used in the outer jacket, made of smooth wall parts made of plastic to support a replaceable, thin-walled inner container (6) made of plastic with a rectangular outline and rounded corners, which has a filler neck (7) that can be sealed by a screw cap (8) and a drain neck (9) to connect a drain valve (10). A sealing cover (11), mounted on the lattice jacket (2) and the support insert (5), is made of plastic or sheet metal. A steel pallet (12) that can be handled by a forklift truck or a storage and retrieval unit for high-bay warehouses or the like, supports the inner container (6), the support insert (5), and the lattice jacket (2). For empty transport and storage purposes, the steel pallet (12) contains a stowage space for the lattice jacket (2) and support insert (5) in the collapsed state.
Abstract:
The lip-type seal for the inlet opening (2) for the dagger board housing and the dagger board (3) exhibits two supporting strips (5) countersunk into the board hull (4) on both sides of the inlet opening (2) as well as two mounting strips (7) with a sealing lip (8) for clamping onto the supporting strips (5), these mounting strips terminating with the profile (6) of the underwater hull and being fashioned as clamping strips. The mounting strip (7) is designed as an L-profile. Respectively one short, perpendicularly bent-away clamping leg (11, 12) is formed at the end edges of the long (9) and of the short leg (10) of the mounting strip (7). The sealing lip (8) adjoining the long leg (9) of the mounting strip (7) is formed, on its longitudinal side facing away from the mounting strip, into a rounded sealing edge (13) passing over into an elastic supporting leg (14) that is oriented obliquely upwardly, this supporting leg being attached to the end edge of the short leg (10) of the mounting strip (7). The sealing lip (8), together with the supporting leg (14) and the short leg (10) of the mounting strip (7), forms an elastic hollow-profile strip (23).

Abstract:
An adjustment fixture for wishbone booms of board-sailing devices comprises two main tubes (1) joined at an acute angle on the mast side, and end tubes (3) telescopically adjustable therein, joined on the side of the stern leech rope. Each end tube (3) has several spaced-apart peripheral grooves (5). A locking ring (7) of rubber or the like is provided, which can engage respectively one of the peripheral grooves (5) and constitutes a tight seal between the main tube (1) and the end tube (3); this locking ring can be locked, with a locking part (6) shaped like an O-ring, into one of the peripheral grooves (5). A conical end section (9) of the locking ring (7) forms a readily handleable transition between the main tube (1) and the end tube (3).
