Title: Expandable stent and method for delivery of same
Inventor: RICCI DONALD R
IPC: A61F2/915
Filed: 1997-03-05
Abstract: An expandable stent comprising a proximal end and a distal end in communication with one another and a tubular wall disposed between the proximal end and the distal end. The tubular wall has a longitudinal axis and a porous surface defined by a plurality of intersecting members comprising a series of longitudinal struts disposed substantially parallel to the longitudinal axis of the stent. Each longitudinal strut in the series comprises flexure means for substantially complementary extension and compression of a diametrically opposed pair of the longitudinal struts upon flexure of the stent. The stent is expandable from a first, contracted position to a second, expanded position upon the application of a radially outward force on the stent. The provision of such flexure means in the series of longitudinal struts leads to a very desirable balance of lateral flexibility of the unexpanded stent and radial rigidity of the expanded stent.

Patent CA-2271557-A1 (CA)
Title: Close prop and latch assembly for stored energy operating mechanism of electrical switching apparatus
Inventor: WEHRLI HANK ANTHONY III
IPC: H01H3/30
Filed: 1999-05-06
Abstract: Electrical switching apparatus such as a power circuit breaker, network protector or switch has a self-supporting operating mechanism module including a cage formed by a pair of side plates rigidly clamped in spaced relation by spacers. The cage supports all of the operating mechanism components including a helical compression close spring mounted fully between the side plates and coupled to a cam member through a rocker in a manner which maintains the forces longitudinal to the spring. The cam member has a charging cam with a charge profile for compressing the close spring and a close profile through which the spring drives the cam member to effect a controlled release of stored energy to close the contacts of the apparatus. A close prop, spring biased to an unlatched position, is latched to secure the close spring in the charged state by a latch assembly reset by a reset lever separate from the close prop which in turn is reset by rotation of the cam member during charging. An interlock prevents release of the close spring when the contacts are closed or the trip release is actuated. An indicator actuated by a driver pivoted against the cam shaft snaps from a DISCHARGED to a CHARGED indication as the close spring becomes fully charged and the driver drops into a notch created by a flat on the cam shaft. A snap action open/closed indicator for the switch contacts is also provided. Both indicators are pivotally mounted in a face plate pinned to the side plates and are connected to the operating mechanism by wireforms. The close and open push buttons snap out to a common shaft and have actuating fingers which trigger releases in the operating mechanism. The close rotating shafts are journaled solely in confronting apertures in the side plates. The cam shaft is captured between bushings seated in non-circular openings in the side plates thereby eliminating the need for any fasteners. Likewise, other parts mounted between the side plates and joined by pins having enlarged heads retained by the side plates do not need retainers. Various shafts extending between the side plates have reduced diameter ends of progressive lengths for successive insertion in one side plate to aid in assembly of the operating mechanism.
