Patent CA-2171677-A1 (CA)
Title: Compact sterile occlusion fastener instrument
Inventor: HUGHETT J DAVID
IPC: A61B17/128
Filed: 1996-03-13
Abstract: A clip applier and method for ligating a tissue structure is provided. The applier has a two stage actuation. In the first stage, a tissue structure is positioned into the jaws of the clip applier The jaws close and lock to a preset force to compress and temporarily occlude the tissue structure. if satisfactorily positioned, the second stage is initiated in which a clip is advanced through the shaft of the clip applier in a closed position. At the distal end of the clip applier, the clip is opened slightly to capture the pre-compressed tissue structure, and is placed over the structure. The clip is then dissociated from the business end of the instrument. Preferably the clip comprises two leg members disposed in close proximity to one another joined from opposing directions by a connecting element. The connecting element restricts separation of the leg members with opposing spring members so as to provide substantially uniform parallel deflection of the leg members from each other.

Abstract: Pieu ou latte pour clôtures et autres applications, dont l'une des faces (5) est pourvue d'une ouverture (6) facilitant la solidarisation d'un élément de fixation (11). Est également décrit un enfonce-pieu manuel destiné à amortir les chocs pendant l'utilisation. Un enfonce-pieu normal comporte un tube, des traverses et des manches, ces éléments formant un châssis rigide. On a modifié cette configuration en montant un élément terminal (35) sur les manches (34), et en interposant des ressorts hélicoïdaux (36) entre la traverse supérieure (33) et l'élément terminal (35). Un bouchon solide (37) est fixé dans l'extrémité du tube (32). L'extrémité du tube (32) qui est voisine de l'élément terminal (35) n'est pas reliée à celui-ci, et les manches (34) glissent librement dans la traverse supérieure (33). Lorsque le tube (32) vient heurter un pieu, le pieu exerce une pression sur le bouchon (37) et, au même moment, les ressorts s'étirent de manière à amortir le choc. Presque instantanément, l'extrémité du tube (32) est heurtée par l'élément terminal (35) de manière à créer un effort supplémentaire dirigé vers le bas.

Filed: 1997-01-06
Abstract: Terephthalic acid is produced by reacting paraxylene with oxygen in a reactor having several vertical stages, the reaction taking place in the liquid phase using acetic acid as solvent and a cobalt-manganese-bromine complex catalyst. During the reaction, a carbon dioxide-containing gas phase is withdrawn from thevapor space of the reactor. The gas phase is cooled to condense vaporized aceticacid therefrom and carbon dioxide is separated from the gas phase and recycled to the vapor space or to the liquid phase or to both of these. In an alternate embodiment, the gas remaining after condensing acetic acid is subjected to catalytic oxidation to oxidize carbon monoxide and methane, if present, to carbon dioxide, and some or all of the carbon dioxide is recycled to the reactor.
