Patent CA-2316211-A1 (CA)
Title: Catalytic gas treatment device
Inventor: HEED BJORN
IPC: F01N13/18
Filed: 1999-01-25
Abstract: A device for catalytic treatment of air or gases. The catalyst is carried on a shaped patterned band. The band is folded into a package (1), which, when received in a casing (2), forms two groups of parallel flow channels having a single connection (9, 10) for incoming and exiting flows at the sides of the package (1), and gas reversal chambers (4, 5) at the package ends. The gas reversal chambers may enclose heating or cooling devices. The exchange of heat between the incoming flow and the exiting flow provides excellent heat economy.
Patent CA-2316882-A1 (CA)
Inventor: GOLDHARDT DONALD J
IPC: A61M39/10
Filed: 1999-01-15
Abstract: A method for placing a feeding tube placement wire in a patient. The method includes the step of providing a placement wire dispenser. The dispenser includes a rotatable placement wire receptacle that defines a placement wire outlet. The dispenser further includes a tube extending outwardly from the placement wire receptacle. The tube defines a placement wire inlet that is in communication with the placement wire outlet of the receptacle. A placement wire is wound about the receptacle, and is in mechanical engagement with the receptacle, such that rotation of the placement wire receptacle causes a first end of the placement wire to be advanced through the placement wire outlet, through the placement wire inlet of the tube, and through the tube. A first end of the tube is constructed for insertion through a patient's abdominal wall and into a patient's stomach. The method further includes the step of placing the first end of the tube through a patient's abdominal wall and into a patient's stomach. Rotational movement is imparted to the receptacle so as to advance the placement wire through the placement wire outlet, through the placement wire inlet, through the tube, and into a patient's stomach.

Patent CA-2320860-A1 (CA)
Title: Feed bottles for babies
Inventor: WILLIAMS STEPHEN JAMES
IPC: A61J11/04
Filed: 1999-02-18
Abstract: A feed and drink bottle is made of plastics material preferably by an aseptic process. In its basic form the bottle (2) has a mouth (4) intended to be sealed with a closure (10) put in place after the feed has been put in the bottle through its mouth. The bottle is rendered unfit for re-use as a baby's bottle, thus making it disposable either by preventing the closure from being able to be removed from the body of the bottle once it has reached its fully engaged position, or by preventing it from being replaced in a fluid tight position once it has been removed. The closure (10) has a teat (24) secured to it in an irremovable manner, as by the teat being clamped between the closure and a retainer member (18) held in place in the closure, or by the teat's being bonded to the closure. When the closure and teat are formed as a single unit, the unit may be used more than once on a body (2) of aseptic plastics material, thus putting back on the user the responsibility of ensuring that the body is sterile or aseptic before such re-use.

Title: Method and system for generating semantic visual templates for image and video retrieval
Inventor: CHANG SHIH-FU
IPC: G06F17/30
Filed: 1999-03-04
Abstract: For database image/video retrieval, a semantic visual template (SVT) is a set of icons of example scenes/objects that characterize a concept, e.g. skiing, sunset and the like. SVTs provide for two-way interaction between a user and a system. The user can provide the system with an initial sketch or example image, as a seed to the system to automatically generate other representations of the same concept. The user then can pick those views for inclusion that are plausible for representing the concept. When an SVT has been established, the database can be searched with it, for the user to provide relevancy feedback on the returned results. With established SVTs, the user can interact with the system at concept level. In forming new concepts, pre-existing SVTs can be used. A limited vocabulary can be parsed, in conjunction with semantic visual templates for querying the system.

Abstract: A method of modulating cytokine mediated hepatic injury by administering deltorphins to a mammal. Deltorphin I SEQ ID NO:1, deltorphin II SEQ ID NO:2 or combinations of deltorphins I SEQ ID NO:1 and II SEQ ID NO:2 may be administered. A deltorphin concentration in the range of about 0.5 mg/kg to about 20 mg/kg in a physiologically acceptable formulation blocks a cytokine cascade in a murine model of septic shock. A therapeutic method of modulating cytokine mediated acute inflammatory, trauma induced and toxin induced hepatic injury, particularly via tumor necrosis factor modulation, is thus disclosed.
