Abstract: ABSTRACT OF THE DISCLOSURE          A high  torque  universal joint  has  a  cross formed by two mutually perpendicular pairs of coaxial trunnions,  each  pair  of  trunnions  being  rotatably received in bearings which in turn are coaxially retained in blind bores in the bearing caps of one of two yokes. the yokes are subdivided into mating half sections which each include one of the bearing caps.   The mating half sections are separably interconnected and are provided with juxtaposed confronting surfaces lying on opposite sides of first yoke reference planes extending through the universal joint center.   The mating half sections have end surfaces which are adapted to abut the flanged ends of  rotatable  elements  at  second  yoke  reference planes.  The first and second reference planes of each yoke are mutually perpendicular, and first and second key members are located respectively at the first and second reference planes.  The restraining forces acting at the first  and  second  yoke  reference  planes  coact  during service of the joint to prevent relative movement between the mating yoke half sections.

Title: Perforated elastomeric soft film and wound dressing made therewith
Inventor: GILBERT EUGENE C
IPC: A61F13/00
Filed: 1987-07-03
Granted: 1993-03-16
Abstract: PERFORATED ELASTOMERIC SOFT FILM AND   WOUND DRESSING MADE THEREWITH            ABSTRACT OF THE DISCLOSURE     The perforations in a film-faced wound dressing  have been discovered to have edges which, though clearly defin-ed, lack the ability to cut the neoepithelium of a healing wound, with the result that the film affords an unexpect-edly high degree of comfort during movement of the patient-and most particularly, when the dressing is changed. This occurs in a thin, soft, self supporting elastomeric film, such as a polyether polyurethane (PPU) film, having less than 10% crystallinity. The film provides a degree of conformability not attained heretofore; has a softness and elastomeric quality which results in reduced shear assoc-iated with the edges of its perforations as compared with the sharp cutting edges of perforations in plastic film; has excellent release characteristics enhanced by less than 25% open area (due to perforations) which minimizes the open area into which the neoepithelium may grow.

Abstract: ABSTRACT OF THE DISCLOSURE:           A pair of catches is mounted on a sliding carriage which is movable forwards and back along a guide between a rear and a front dead centre,  the catches being pivotable backwards and forwards between a working position and a position of rest.  In order to move the sliding carriage along the guide, a crank drive is provided.  This has a crank, which can be driven in rotation, and a connecting rod, which is connected by a crank pivot joint to the crank and by a connecting-rod pivot joint to the sliding carriage.          A control mechanism allows the catches to assume their working position near the rear dead  centre of the sliding carriage for its forward movement and to assume their position of rest near the front dead centre of the sliding carriage for its backward movement.   The control mechanism comprises a bistable spring arrangement which is disposed between the connecting rod and the catches and assumes each of two stable end positions  once  during each complete revolution of the crank.
