Patent BR-8505115-A (BR)
Inventor: ROTHFUSS ROBERT G
IPC: A61B17/115
Filed: 1985-10-15
Abstract: (57) A surgical stapling instrument suitable for performing a gastrointestinal anastomosis is provided. The stapling instrument incorporates a staple height adjusting mechanism which enables the gap between its jaw members to be adjusted to select different staple heights to be produced when the staples are formed. Preferably, the stapling instrument includes a pair of elongate jaw members, one of which supports a staple cartridge adapted to receive at least two laterally spaced longitudinal rows of staples, and the other provided with an anvil adapted to form the staples. A pusher bar and knife assembly slidable longitudinally relative to the jaw members sequentially drives the staples from the cartridge and forms the staples against the anvil to produce a pair of laterally spaced rows in the tissue. The pusher bar and knife assembly includes a knife blade for cutting the tissue along a line between the longitudinal staple rows. A set of jaw support members is carried by the knife blade which travel along the elongate jaw members as the pusher bar and knife assembly is advanced to provide local support to the jaw members. The angular orientation of the knife blade relative to the jaw members is adjustable by the staple height adjusting mechanism to vary the vertical spacing between the jaw support members as the gap between the jaw members is varied.

Abstract: An apertured film, suitable for use as a sanitary napkin cover which passes body fluids, is provided. The film comprises a first layer of a first polymeric material and a second layer of a second polymeric material. Both layers are apertured for the transmission of body fluids therethrough. The first polymeric material exhibits a melting point temperature which is greater than the melting point temperature exhibited by the second polymeric material. The apertured film may be thermally bonded by heating the film to a temperature in excess of the melting point temperature of the second layer material and below the melting point temperature of the first layer material. The unmelted first layer will thereby maintain the integrity of the apertured film when the second layer is in its thermally softened condition.

Abstract: Catalyst solution contaminated during the carbonylation of methyl acetate and/or dimethylether. To this end, the contaminated catalyst solution is subjected in a first processing stage to extraction with a dialkylether and alkanol, each of which has from 1-4 carbon atoms per alkyl group, and thereby freed from its organic contaminants, from acetic acid, acetic anhydride and ethylidene diacetate, and the ether phase is separated from the purified promoter-containing catalyst solution; next, the ether phase is treated in a second processing stage with iodine and/or methyl iodide; the precipitated promoter containing catalyst complex is separated and dissolved in the purified catalyst solution coming from the first processing stage; the ether phase is separated into its constituents by distilling it; recovered dialkylether and alkanol are used again in the extraction stage; fresh catalyst solution is prepared from the recovered mixture of acetic acid, acetic anhydride and ethylidene diacetate and from the united purified catalyst solution while residual dialkylether and alkanol are distilled off, and the organic contaminants retained in the residue of the ether phase distillation are expelled.

Abstract: The invention proposes a method for the production of nestable parts, at least one part being produced by powder diecasting. To compensate for the shrinkage of the part produced by powder diecasting and, if required, to provide additional play, a separating layer (5) of plastic is applied between the nestable parts. After the casting operation, the separating layer and the binder are eliminated during the binder-elimination and sintering process. The method can also be used in metal-powder extrusion for the production of two-layer metal profiles. <IMAGE>

Abstract: A composition is disclosed which can hydrophilify the surface of a member to impart an antifogging property to the surface of the member. The composition for hydrophilifying the surface of the member comprises at least (a) photocatalytic particles of a metallic oxide, (b) a precursor capable of forming a silicone resin film or a precursor capable of forming a silica film, and (c) a solvent, the total content of the photocatalytic particle and the solid matter of the precursor in the composition being 0.01 to 5% by weight. The hydrophilic property can be imparted simply by applying the composition onto a member and drying or heating the composition applied to the member. The resultant hydrophilic thin film is transparent and, hence, does not sacrifice the transparency and appearance of a member required to be transparent. Further, the surface of a member with the above composition applied thereto has such a property that water droplets adhered thereon can be immediately removed by vaporization and the surface is less likely to be soiled and, even when a contaminant is adhered thereon, can easily release the contaminant therefrom. <IMAGE>
