Abstract: A prosthetic ligament (1) for implantation between at least two bones (5,6) and which takes the form of a tubular body made of woven flexible material through which tissue ingrowth can take place after implantation. A cord (3a) is attached to one end of the ligament (1) to thread and to pull the ligament through channels formed in the bones, and a protective detachable sheath (2) is attached to the ligament in order to facilitate the implantation of the ligament as it is pulled through the channels, the sheath immediately thereafter being detached. A bone plug introducer (8 to 12) is used to insert a bone plug into one end of the ligament within the bone tunnel, which thereby secures the ligament end in position.

Abstract: Shaped articles, especially ones containing a plurality of fine through passages, are made from a composition containing a refractory particulate material by extrusion, cutting into lengths while in the green deformable state by means of a high velocity water jet generator (8), and then calcining to bind the refractory particles together. Depending on the nature of the refractory material, the articles are of use as catalyst supports or precursors, adsorbents, or absorbents. In a preferred mode of operation, the extrudate is extruded horizontally and allowed to sag into a gap between the extrusion die and a transport device, which is driven positively to maintain the degree of sag within predetermined limits, and the frequency of cutting depends on the rate of movement of the transport device.

Abstract: A resilient shaft coupling having two metal parts that include an inner coupling ring and, coaxial thereto, an outer coupling ring. The facing generated surfaces of the rings are formed with a number of substantially radial cams or dogs which mesh with one another alternately in the circumferential direction and extend to near the pertaining opposite generated surface. Each two circumferentially consecutive cams or dogs form a pair whose adjacent surfaces are concave and delimit a chamber whose longitudinal axis extends parallel to the rotational axis of the coupling, and in which a resilient coupling member is disposed. The coupling members are radially biased or pre-loaded by a predetermined amount, and are secured to the generated surfaces of the inner and outer ring coupling rings. With the coupling in its rest position, gaps or spaces are present between each resilient coupling member and each cam or dog, and permit the members to deform freely and thus to be stressed in shear. The advantage of this shear compression is that the coupling has a very reduced torsional stiffness at low torques, and operates without backlash or play at low torques.

Abstract: In this device, two parallel incremental tracks (5, 6), which are offset with respect to one another by T/4, of the same incremental period T are arranged on a scale (1) on both sides of a reference marker (7).

Due to the symmetric arrangement of the incremental tracks (5, 6) relative to the reference marker (7), the required relation between the reference pulse (UR, URF) and the counting signals which are obtained from the analog scanning signals of the incremental tracks (5, 6) is retained even when the scanning plate (2) is tilted relative to the scale (Figure 1). <IMAGE>

Abstract: The bottle stopper for freeze drying is made of rubber-elastic material and consists of a peg (1), having an essentially cylindrical outer circumferential surface (10a, 10b), and a circular flange (2) which is integral with said circumferential surface. The peg contains a hollow space (4) which is open towards the free peg end face (3) and, via a slot (11) towards the axially outer part of the circumferential surface (10b). Projecting from the outer circumferential surface and spaced apart are three cams (14a-14c) which are constructed as elongate beads and whose axially outer boundaries are located on a common transverse plane (Q3) adjacent to the peg end face. Constructed in the axially outer circumferential surface (10b) is a circumferential groove (16), whose axially inner side wall is located in the transverse plane (Q3). The cams define a first insertion position of the stopper, in which the container is still in connection with the atmosphere via the hollow space and the slot. The groove allows use of a stopper model both for containers with a completely smooth cylindrical borehole of the bottle neck and for those which have an inwardly projecting rib at the transition from the borehole to the end surface of the neck. <IMAGE>
