IPC: A61B1/04
Filed: 1993-11-12
Abstract: A trocar has an elongated shaft (12) and a cutting element (28) is attached to a distal end (16) of the shaft. The cutting ele-ment can be a transparent puncturing head formed integrally with the shaft, and a distal portion of the puncturing head is confi-gured as a regular triangular pyramid having three sharpened cutting edges (36, 38 and 40). Alternatively, the cutting element can be three or four metal cutting blades (52, 54) which are attached to the distal end of the shaft. In either case, a pathway for light communication is established from the cutting element through the shaft, a portion of which is transparent. The shaft has a cavity (18), and a rigid endoscope (20) is positioned in the cavity to collect light from the distal end of the shaft. A video monitor (24) is connected to the endoscope for displaying an image of the path of advancement of the trocar.

Title: Membrane formed by an acrylonitrile-based polymer
Inventor: GENTILE FRANK
IPC: C08J5/22
Filed: 1994-04-26
Abstract: A permselective graft polymer is disclosed that is formed by converting into intermediate reactive sites a portion of the cyano groups of a backbone polymer containing (a) units, and grafting polyalkylene oxide polymer chains to the backbone polymer through the reactive sites. Either the backbone polymer of a polymer resin or a permselective polymer membrane can be grafted. When a resin is used, it is formed into a permselective polymer membrane using known methods. The resulting permselective membrane can be formed into hollow fibers or flat sheets for the encapsulation of living cells. The encapsulated cells are then implanted into a patient in need of the biologically-active factors produced by the cells. The permselective graft polymer membrane exhibits good molecular diffusion with minimal protein adsorption.

Title: Apparatus and method for temporarily plugging a tubular
Inventor: SNIDER PHILIP M
IPC: E21B34/14
Filed: 1995-07-28
Abstract: An apparatus and method for controlling the pressure at which a fluid is introduced into a well penetrating a subterranean formation. The apparatus comprises a blow out sub having a sealed chamber (34) between two plugs (18, 26).  The chamber is filled with a fluid at a known pressure.  Thus, the pressure required to release the first plug (18) is independent of the pressure in the well below the sub.  The sub is attached to a tubular and positioned within the well. The first plug is then released upon application of a predetermined pressure fluid pressure, and the second plug (26) is released upon application of a lesser pressure.  The blow out sub may additionally comprise a tube (152) forming a channel through the first plug (118), the chamber (134), and the second plug (126), with a means (154, 156) for controlling fluid flow through the channel.

Title: Antiperspirants containing aerogel particles
Inventor: ROUANET STEPHANE FABRICE
IPC: A61K8/33
Filed: 1994-11-07
Abstract: A method for providing aerogels, and aerogels produced according to the method is described. The method involves contacting a solution containing material to be processed with a species selected to precipitate the material and selected so as to be miscible with the solvent system of the solution. After the material is precipitated, the material may be washed with the precipitating species until it is substantially free of solvent system. Then the precipitating species containing the material precipitate is taken above its critical point, and the supercritical fluid is exhausted above its critical temperature. Alternately, a separate isolating species is introduced to displace the precipitating species, or the precipitating species/solvent system mixture. The isolating species then is taken above its critical point, and exhausted above its critical temperature. The invention provides for batch or continuous processes. <IMAGE>

Inventor: KAWAGUCHI MASAHIRO
IPC: F04B49/00
Filed: 1996-06-12
Abstract: A variable displacement compressor which has a suction chamber,  a discharge chamber,  and a crank chamber.   The displacement of the compressor is controlled by supplying refrigerant to the crank chamber from the discharge chamber via a pressurizing passage and releasing the gas into the suction chamber via a pressure releasing passage.  An increase in the pressure in the crank chamber decreases the displacement, and a decrease in the pressure in the crank chamber increases the displacement.   A displacement controlling structure of the compressor includes an electromagnetic valve which alters the size of an area of the pressurizing passage.   A computer controls the electromagnetic valve in accordance with commands to alter the displacement.  The computer enlarges the opened area  of  the  pressurizing  passage  by  controlling  the electromagnetic valve in response to commands to reduce the displacement.
