  • Patent number: 6331090
    Abstract: Device for establishing a gastight and fluidtight connection in a horizontal level between two or more containers (100, 200) of the iso-container type. The device includes a substantially band shaped, elastic sealing member (300) which surrounds an opening (20) between the containers to be connected and which is arranged on a supporting surface (105). A pressure exerting member (130) is provided to hold the sealing member (300) tightly against the supporting surface (105) with tightening members (400) to force the sealing member (300) against the supporting surface (105). The sealing member (300) in mounted position is arranged with a generally rectangular cross section and is placed against a supporting surface (105) on the respective containers, generally extending in the main level of the respective containers. The pressure exerting member constitutes at least four generally band shaped members (130) arranged at the respective flat supporting surfaces (105) of a container (100).

  • Patent number: 6106183
    Abstract: The clamping device serves for the releasable connection of two profile pieces, it being possible for an insert core (1) to be introduced and fixed in a first of the profile pieces, in which insert core an axially movable slide (7) bears two pivotable clamping elements (11) each with a clamping hook (13; 14) which can be introduced at least partially into an opening of a second profile piece (15) in order to exert a clamping pressure on that section of the second profile piece (15) which partially closes off the opening. The insert core (1) has eccentric means (5) in order to displace the slide (7) axially. Two oblique surfaces (43) are provided in the insert core (1) in order to displace the clamping element transversely during its axial displacement. In addition to the clamping hook (13; 14), the clamping element (11) comprises a strip-like part with a bent-over strip end designed as hinge hook (34).

  • Patent number: 6098476
    Abstract: A flange portion formed on an inner periphery of a flywheel is fitted to an end of a crankshaft. A spline piece is fitted to an inner peripheral surface of the flywheel. The flange portion of the flywheel and a flange portion of the spline piece are commonly fastened to the end of the crankshaft by bolts. An upper end of a driving shaft is spline-fitted at a point into a driving shaft coupled portion of the spline piece which is accommodated in an internal hole in the crankshaft. Thus, in coaxially coupling the flywheel and the driving shaft to the end of the crankshaft, it is possible to make such a coupled area compact and to reduce vibration by an accurate centering thereof.

  • Patent number: 5875600
    Abstract: An improved joint construction for commercial metal doors is disclosed which utilizes a novel force transfer block. The force transfer block has spaced-apart flanges which engage corresponding reglets in a door stile. The inner faces of the flanges bear against the inner walls of the reglets. The flanges of the force transfer block are configured such that they will retain the block on the stile by way of an interference fit with the walls of the reglet. Thus the block does not have to be separately fastened to the stile. A rail abuts the stile and has a recessed portion into which the block is received. A threaded rod extends through the rail and into the stile, and tightening a threaded fastener onto each end of the rod clamps the rail securely between two stiles. The recessed portion of the rail has surfaces bearing snugly against at least two sides of the block such that twisting forces applied to the rail are transferred to the block.

  • Patent number: 5810502
    Abstract: For mounting the hollow ends (H) of a curved handle (G) in an orifice (B) on a contact face (A), a guide member (30) for a screw (29) has a base flange (31) which can be connected to expanding parts (39, 40, 60, 64) or a securing member (47) and on which there rests a tubular supporting member (12) which overlaps the hollow end (H). A cap nut (20) having a peripheral groove (24) for fixing the hollow end (H) through a setscrew V and wrench faces (33 and 23) like the head (32) can be screwed on to a head (32) of the guide member (30). A shank (37) of the guide member (30) with a conical end (39) or conical nut (64) directed against it can be pulled into an expanding nut (40) or an expanding tube (60) by means of the screw (29), enlarging an expanding basket (42, 62). A door handle (50) can be fixed, for example, on a multi-chamber profile (M), with the securing of a polygonal pin (47), the guide member (30) being secured externally by a flange ring (55).

  • Patent number: 5716155
    Abstract: The present invention relates to a T-shaped connection frame for connecting car frames, in which a first member is connected to a second member via a joint member to form a "T." The joint member is formed by symmetrically dividing a rectangular tube between its two latch teeth located at the upper-center and lower-center inner walls. The rectangular tube also has protrusions at the left and right exterior walls. The joint member divided in this way has the latch teeth at the upper and lower tips of the mouth formed by the division and has the protrusion situated opposite the mouth so that the first member can be snapped on easily to this mouth and the second member can be attached to the protrusion at the opposite side. This structural arrangement makes the positioning of the frames very simple, obviates a make-shift attachment, and, at the same time, reduces the number of operation steps.

  • Patent number: 5651631
    Abstract: A tool handle assembly includes a molded adapter bonded to the end of a handle shaft, which adapter includes a generally cylindrical cap portion and a generally tapered frustoconical portion that surrounds the handle shaft adjacent to the cap portion. The handle assembly is inserted into a lower entrance of a tapered eyehole of a tool head such that the frustoconical portion of the adapter engages a portion of the eyehole. In one preferred form, the cap portion of the adapter includes external barbs. A pair of arcuate wedges having interior teeth are inserted between the cap portion of the adapter and the tool head and bear on the major axis of the tool head. The teeth of the wedge cooperate with the barbs of the adapter to secure the wedges in place. In another preferred form, the adapter includes a pair of slots into which wedge inserts are driven to expand the cap portion of the adapter and thus secure the tool head to the handle assembly.
