Abstract: During the assembly of signal devices, such as limit switches and the like, on swivel drives for actuating pipe valves and for similar devices, there are difficulties to the extent that signal devices of the most different type and size are used which normally have to be fitted by means of screw attachment bolts to assembly plates or assembly links provided with corresponding holes or threaded openings, in specific positions with respect to actuating elements, such as switching arms, switching cams or cam discs, which project from the rotation axis of the swivel drive to the side. These and other difficulties are overcome in that an assembly unit (7) is provided, which is suitable for the most varied types and sizes of signal and control devices and is constructed as a clamping attachment device having a base part (8) which is attached to the swivel drive (1) and having a displacement part (9), which supports the signal device (4), in such a manner that the signal device (4) can be clamped firmly in respectively different positions on the base part (8) on the "x" and "y" coordinates of a spatial coordinate system, which coordinates are formed by displacement tracks on the base part (8) and on the displacement part (9), with respect to the "z" coordinate, which coincides with the rotation axis (2) of the swivel drive (1). <IMAGE>

Title: Antibody antagonists of human interleukin-4.
Inventor: RAMANATHAN LATA
IPC: A61K38/00
Filed: 1990-12-18
Abstract: Two kinds of antibody antagonists of the binding of human IL-4 to cellular receptors are provided by this invention. Some of the antagonists bind to specific regions of IL-4 which are believed to be involved in interactions between IL-4 and its receptors. Because of this specific binding by the antibodies to the IL-4, the binding of the IL-4 to the receptors is substantially inhibited. The other antibody antagonists of the invention are anti-idiotypic antibodies which, while lacking IL-4 activity, appear to mimic IL-4 and to compete directly with it for binding to the cellular receptors. Polypeptides used to make the antibody antagonists are also provided, together with methods for using the antagonists to inhibit the binding of IL-4 to its cellular receptors.

Title: Quick change clamping mechanism.
Inventor: ERICKSON ROBERT ALFRED
IPC: B23B29/00
Filed: 1990-12-17
Abstract: A clamping assembly for releasably holding a tool holder having a shank includes a tool support member having a bore extending along a longitudinal axis. A locking mechanism is disposed in the axial bore for securing the tool holder to the support member. The locking mechanism includes a lock rod having first and second contact surfaces mounted in the support member. The lock rod moves along the longitudinal axis between a locked position and a release position. A wedge rod is mounted in the support member for reciprocal movement along an axis angularly disposed with respect to the longitudinal axis. The wedge rod has first and second wedge surfaces which incline in parallel fashion from opposite edges of the wedge rod. First and second force transmitting elements are interposed between the wedge surfaces of the wedge body and the contact surfaces of the lock rod. When the lock rod is moved in first direction, the first force transmitting element is moved outward with respect to the transverse axis into contact with the first support surface and pushes the lock rod towards a locked position. When the wedge rod is moved in a second direction, the second force transmitting element is moved outward with respect to the transverse axis into engagement with the second contact surface of the lock rod and moves the lock rod towards a release position.
