Inventor: PETERS RUDOLPH
IPC: A61B17/068
Filed: 1986-04-25
Granted: 1990-09-25
Abstract: ZS8 ABSTRACT METHOD AND APPARATUS FOR STORING, DISPENSING AND APPLYING SURGICAL STAPLES A method and apparatus for storing and automa-tically dispensing and applying surgical staples in serial fashion includes a pistol-like tool having means for storing a large plurality of staples in parallel, stacked column fashion aligned along the longitudinal (barrel) axis of the tool. A form tool and an anvil tool extend longitudinally parallel to the axis, and are advanced in synchronism by actuation of a trigger lever. The form tool includes a pair of arms which impinge upon and rotate the legs of the staple about the web portion thereof to dispose the staple in a points-first dispensing orientation. The form tool advances the staple to the distal dispensing end of the tool, where it drives the staple into a portion of the anvil and crimps the staple thereabout. Release of the trigger causes an elevator member to separate the next distal staple in the column from its column alignment into position to be engaged by the anvil tool and form tool at the start of the subsequent dispensing cycle. A trigger actuation mechanism prevents release of the trigger lever until the dispensed staple is completely crimped in the tissue.

Abstract: AXIAL SEALING MECHANISM FOR     SCROLL TYPE FLUID DISPLACEMENT APPARATUS          ABSTRACT OF THE DISCLOSURE        A scroll type fluid displacement apparatus with an axial sealing mechanism is disclosed. The compressor includes a pair of scrolls each of which comprises an end plate and a spiral element extending axially from one end surface of the end plate. A groove of uniform depth is formed in the axial end surface of each spiral element and a seal element is disposed within each of the grooves to seal the fluid pockets defined by the scrolls. The axial thickness of the seal element at the center thereof is smaller than the depth of the groove and the axial thickness of the seal element at the outer portion thereof is larger than the depth of the groove. Accordingly, when the compressor is assembled, an axial gap between both scrolls is fixed by the seal element, and the devices can accommodate thermal expansion of the spiral element because of the temperature rise in the fluid upon compression.

Abstract: ABSTRACT      This invention relates to an improved method of manufacturing a heat exchanger element.  In a second aspect the invention concenrs a heat exchanger element itself.  In the third aspect the invention concerns a reservoir suitable for housing the heat exchanger element to form a heat exchanger.    The element is manufactured by extruding polyethylene tubes and winding them into spiral coils.  Each coil is located along the length of a rigid horizontal spacer bar in order to maintain even spacing of the coil.  The element comprises a stack of coils which are not restrained against vertical movement.  The element also comprises a cylindrical void through the centre.
