Abstract: The present invention relates to a separable fastening device provided for releasably fastening a first surface to a second surface. The separable fastening device comprises a first fastening element (14) of high static vinyl material which is attached to the first surface (24), and a second fastening element (16) of high static vinyl attached to the second surface (32). When the first fastening element (14) and the second fastening element (16) are placed against each other in a face-to-face relationship, the attractive forces between the first and second fastening elements form a separable bond between the first and second surfaces.

Abstract: A front-loading syringe which comprises a movable plunger for injecting liquid contrast media, is rotatably mountable on a front wall of an injector housing with an interference fit and in sealed relationship with respect thereto, with or without a pressure jacket, by a first-quick release mechanism. At the same time, the plunger is connected to an injector drive mechanism by a second readily releasable mechanism. During the mounting operation, a sensor reads injection information from an indicator device on the syringe and feeds it to an injector control. An audible-and-tactile indicating mechanism also is activated when the syringe is essentially in the desired mounted position. The syringe may include reinforcing ribs which also function as volumetric gradations, and liquid media presence-or-absence indicating dots which appear circular against a liquid media background and oval-shaped against an air background. An injection end of the syringe comprises an injector portion of reduced diameter inside a screw-threaded attachment portion of larger diameter, and may include loop-shaped reinforcing handle portions.

Title: High force thermochemical actuator
Inventor: SCHNEIDER EDWARD T
IPC: F15B21/06
Filed: 1991-06-12
Granted: 2000-11-07
Abstract: A pressure vessel (A) is defined by end walls (16) and side walls (18). In the interior, a plurality of fins (12) define an assembly of thin passages (10) that are filled with a material (26) that expands as it changes from a solid to a fluid state. The passages are thin, on the order of 0.01 inches such that heat is transferred relatively quickly into and out of the material. The passages communicate with a manifold area (14) to a piston bore (40) or other structure (B) for converting fluid pressure into mechanical movement. The piston bore holds a low durometer seal (44), a higher durometer seal (46), and a movable piston (42). To generate rotary motion, the piston and vessel assembly are mounted for rotation about an eccentrically placed member (88). As the pressure vessel goes through heating and cooling reservoirs, the pistons expand and contract causing rotation (Figs. 5-7). In another application, at least two of the assemblies are interconnected by a heat pump (94) such that heat can be moved back and forth between the two. Additional heat pumps are provided for moving heat from the ambient air or other sources of heat to the pressure vessels (fig. 8). The actuator is also used to control a two position valve (fig. 10) and a three position valve (Fig. 1 I). A pair of actuator vessels (170, 172) are connected by a common heat transfer device (174) for causing differential movement between pistons (176, 178, Fig. 13).

Abstract: A forearm lifter for assisting in the articulation of a mating forearm part of an arm prosthesis with respect to a mating upper arm part about at least one elbow axis is disclosed. The forearm lifter includes: (i) a spring element; (ii) a mechanism having an input and an output, with the spring element directly or indirectly applying a tensile force to the input of the mechanism; and (iii) a tension element having one end acted upon by the output of the mechanism, and having another end which can be fastened at a fixed point on said mating upper arm part. The fixed point and the elbow axis define a torque lever, such that the force that is transmitted through the mechanism from the spring element applies torque to the mating upper arm part in such a manner that the curve of the torque acting at the fixed point, plotted against the angle of articulation of said forearm part, is approximately parabolic. The torque has its minimum values in both the forearm extended position and at maximum forearm bending. The torque has its maximum value when said upper arm mating part and said forearm are at approximately 90°.
