Patent CA-2191372-A1 (CA)
Inventor: YAMADA IKUFUMI
IPC: A61F2/08
Filed: 1996-11-27
Abstract: Disclosed is an improved screw member adapted to be threaded into a gap between two bone parts in BTB tendon transfer surgical operations, and a fixation tool for engaging the screw member. The screw member typically consists of a hollow cylindrical member comprising an axial bore having a hexagonal cross section, and an outer circumferential surface provided with a strictly straight thread. The fixation tool comprises a transmission shaft having an intermediate section having a hexagonal cross section complementary to that of the axial bore of the screw member. Because the transmission shaft is entirely passed through the axial bore of the screw member, the torque for turning the screw member can be positively transmitted to the screw member, and the transmission shaft provides a positive guide action for the insertion of the screw member. The transmission shaft may be either axially slidably but rotatively integrally engaged to a handle grip or integrally attached to a handle grip.

Title: Molten carbonate fuel cell and power generation system including the same
Inventor: UEMATSU HIROYOSHI
IPC: H01M8/14
Filed: 1996-12-13
Abstract: The molten carbonate fuel cell includes (a) an anode current collector formed to be flat rectangular tubular and having a pair of outer surfaces each formed at the center thereof with a recessed portion for receiving an anode therein, the recessed portion being formed with a plurality of holes through which anode gas is supplied to anode from inside of the anode current collector,(b) a pair of cells each disposed on each of the outer surfaces of the anode current collector, and (c) a pair of cathode current collectors each cooperating with the anode current collector to sandwich each of the cells therebetween, the cathode current collectors being formed with a plurality of holes through which cathode gas is supplied to cathode from outside of the cathode current collector. The anode current collector the cells and the cathode current collectors constitute a pair of independent parallel cells. The anode current collector includes an anode gas passage which is connected to the anode current collector and through which an anode gas is to be provided to the inside of the anode current collector, and an anode current terminal formed at an end of the anode current collector perpendicular to the anode gas flow. Each of the cells includes an anode set in the recessed portion of the anode current collector, an electrolyte plate disposed in contact with an outer surface of the anode and extensive over the recessed portion of the anode current collector, and a cathode disposed in contact with an outer surface of the electrolyte plate. The cathode current collectors is connected to each other at ends disposed opposite to the anode current terminal to form ~ shape, and the cathode current collector is formed at a connection point as a cathode current terminal. The above mentioned molten carbonate fuel cell makes it no longer necessary to use a separator for mechanically separating anode and cathode gases, resulting in remarkable cost down.

Title: Materials and methods for detection of oxalate
Inventor: PECK AMMON B
IPC: C12Q1/689
Filed: 1995-06-20
Abstract: The subject invention concerns the novel use of formyl-CoA transferase enzyme together with oxalyl-CoA decarboxylase enzyme for the detection and measurement of oxalate in biological samples. The use of enzyme system according to the subject invention results in the conversion of oxalate into carbon dioxide and formate. Because the production of formate is directly correlated to the concentration of oxalate present in a sample, the determination of the resulting formate concentration provides an accurate, sensitive and rapid means for detecting even low levels of oxalate. The subject invention further concerns the cloning, sequencing and expression of the genes that encode the formyl-CoA transferase enzyme and the oxalyl-CoA  decarboxylase enzyme of Oxalobacter formigenes. The subject invention also concerns a method for detecting the presence of Oxalobacter formigenes organisms in a sample, and the polynucleotide probes and primers used in the detection method.

Abstract: A sustained-release preparation containing a water-insoluble or slightly water-soluble polyvalent metal salt of a water-soluble peptide type of physiologically active substance except for an endothelin antagonist and a biodegradable polymer. The present invention is a sustained-release preparation that is highly efficient in incorporating a water-soluble peptide type of physiologically active substance except for an endothelin antagonist and suppresses initital burst of the water-soluble peptide type of physiologically active substance except for an endothelin antagonist. The sustained-release preparation of the present invention is capable of releasing the water-soluble peptide type of physiologically active substance except for an endothelin antagonist while retaining its bioactivity after administration in vivo. Furthermore, the water-soluble peptide type of physiologically active substance except for an endothelin antagonist in the sustained-release preparation is kept stable for a long period of time, with little loss of bioactivity.

Abstract: In a signal transmission chain containing, for example MPEG2 coders (12, 20, 28) and decoders (24, 30), an information channel extends throughout the signal chain. Signal processing elements in the chain take advantage of information (VP) on the information channel and also add to it information (VP) concerning the process performed by that signal processing element. The information channel, towards the end of the signal transmission chain, therefore carries information (VP) relating to all or most of the various processes performed by in the chain.

Title: Method and apparatus for deploying an expendable autonomous underwater vehicle from a submarine
Inventor: PATTEE WILLIAM D
IPC: B63G8/00
Filed: 1996-05-15
Abstract: An expendable autonomous underwater vehicle (10) is deployed from a trash disposal unit (32) of a submarine (30) into a body of water. The vehicle (10) and one or more launch-aiding components (44, 46, 51, 52, 60, 72) are inserted into the trash disposal (32) in an arrangement that results in safe and reliable deployment from the trash disposal unit. The launch-aiding components keep the vehicle in a predetermined orientation within the trash disposal unit prior to deployment and protect the trash disposal unit from damage. The launch-aiding components also aid the vehicle in ejecting from the trash disposal unit and descending into the body of water to a depth at which the vehicle can begin its autonomous operation. In general, the vehicle must be a safe distance away from the submarine before it begins operation. The launch-aiding components fall away from the vehicle in the body of water as the vehicle descends thereinto. The expendable autonomous underwater vehicle, which is typically used by submarine personnel as a training target, drops to the bottom of the body of water after its internal battery is exhausted.
