Title: Optionally engageable fluid friction coupling
IPC: F16D35/00
Filed: 1988-10-11
Granted: 1989-09-14
Abstract: The invention relates to a fluid friction coupling 15 which is configured such that it can be engaged. To this end, the hub 18 is provided with inner lamellas 20 which are arranged such that they are rotationally fixed but can be displaced axially. The housing 17 has supporting rings 23 which are accommodated in keyways 21 in a rotationally fixed and axially displaceable manner. Accommodated between the support rings 23 are loosely inserted outer lamellas 19. When the hub 18 and housing 17 are subjected to pressure by means of an operating device, for example 16a, the outer lamellas 19 are subjected to pressure by way of a pressure disc 25a, i.e. a frictional engagement between the outer lamellas 19 and support rings 23 is produced, by means of which a rotationally fixed connection to the housing 17 can be made. In the disconnected condition a relative rotation of the hub 18 and housing 17 does not produce a substantial build up of torque, whilst if the outer lamellas 19 are secured, a large-surface shearing of the silicone oil in the housing interior 24 takes place and hence a torque from the driving part, for example the hub 18, can be passed on to the housing 17. <IMAGE>

Title: Unloading station for a swinging-bucket conveying installation
IPC: B65G47/40
Filed: 1988-10-13
Granted: 1989-08-31
Abstract: An unloading station for a swinging-bucket conveying installation comprises a conveying chain on which the swinging buckets (2) are suspended so as to be rotatable about a horizontal axis (1) running above their centre of gravity. Provided, below the axis (1) of rotation, on a swinging-bucket side wall (3) is a cam (4, 9) which is curved in the direction (5) of movement of the conveying chain in the direction of a shorter vertical distance from the axis (1) of rotation. A guide curve which is fixed on the frame and cooperates with the cam (4) has, in the conveying direction (5), a first section in which the distance from the conveying chain decreases so that the cam (4) runs, in the region (9) of its curvature, along the guide curve and the swinging bucket (2) is rotated about its axis (1) of rotation, and a second section in the conveying direction (5), the distance from the conveying chain of which section decreases. So that such an unloading station functions more reliably and can be adapted simply to different conditions, the cam (4) has a first rectilinear section (8) which adjoins the lower part of the curved section (9) in the direction counter to the conveying direction (5) preferably tangentially, and preferably runs horizontally (Figure 1). <IMAGE>

Granted: 1992-06-25
Abstract: A bone dowel assembly for attaching a tissue to a bone includes an approximately cylindrical shank having a continuous borehole which extends axially from a free end of the shank to a second end of the shank, and two slots in the outside surface of the shank which communicate with the borehole and extend from the second end of the shank partially along its length to form reeds or tines which expand radially outwardly when an expansion part is forced into the borehole. The expansion part is conical and includes at least one aperture which extends through the expansion part transversely to the longitudinal axis of the shank. Before insertion into a hole drilled in the bone, the assembly is threaded from the free end of the shank through the borehole, out through one of the slots, past an outside portion of the expansion part, through the aperture, again past an outside portion of the expansion part, through the other slot, and back through the borehole to the free end of the shank. The assembly is then inserted, expansion part first, into the hole in the bone and the suture is pulled, while holding the assembly in place, to force the expansion part into the borehole, causing the reeds to expand radially outwardly and wedge against the sides of the hole in which the assembly is placed. The expansion part and shank may be integrally molded and the connecting zone scored or perforated such that the connection or link between the expansion part and shank is broken when force is applied to pull the expansion part into the borehole.

Title: Twisting unit for cable ply twister - has freely revolving twisting head incorporating horizontally freely shifting bridge and has guide roll at each end
IPC: D01H13/10
Filed: 1992-01-31
Granted: 1993-05-06
Abstract: A twistind unit for a ply twister features a freely revolving twisting head which incorporates a bridge that shifts freely and horizontally and carries a guide roll at its two opposite ends. Each of the yarns is guided via one of the guide rolls and comes from a bottom roll located on the other side of the rotation axis. The yarn is then led on to a central bore located in the twisting head. A display unit is coupled to the bridge and displays the shifting path of the bridge in relation to the rotation axis. The shifting is caused by an unequal tension of the two yarns on the underside of the twisting head. The displayed path is received by a contact-free receiver, which relays it to an electronic evaluator and regulator unit which controls the yarn brake of the yarn drawn from the static feed package. ADVANTAGE - The unit ensures that the tensions of the two yarns to be twisted are compared to each other automatically before twisting. The yarn brake braking the first yarn is regulated to ensure identical tensions.
