Title: Multi-way valve and water purifier using the same
Inventor: YONEZAWA YASUO
IPC: F16K11/056
Filed: 1996-11-15
Abstract: Disclosed is a multi-way valve comprising a valve casing having a fluid inlet and a plurality of fluid outlets, first and second chambers defined in the valve casing, a partition disposed between the first and second chambers and having a plurality of fluid paths, a plurality of valve elements each engaging a corresponding fluid path from the first chamber side for opening and closing the fluid path and a driving device having cams which selectively drive the valve elements from the second chamber side. The multi-way valve can be manufactured as a small-sized one, and therefore, a water purifier using the valve also can be assembled as a small-sized one as a whole.      The amount of resident fluid in the valve can be decreased, thereby improving the hygienic property of the water purifier.      The operation for taking off or exchanging valve elements can be simplified.
Patent CA-2191105-A1 (CA)
Inventor: KISS GUNTER H
IPC: C10J3/08
Filed: 1995-06-09
Abstract: A process for the high-temperature gasification of possibly thermally pretreated heterogeneous wastes, in which oxygen is injected into the gasification bed with the aid of water-cooled oxygen lances.  The oxygen is heated by an independent pilot flame and accelerated to speeds approaching the speed of sound.  Accordingly, the oxygen lances cannot be plugged by melted charge components not susceptible to gasification because the pilot flame is driven independently of the oxygen-lance flow.  A pulsing, phase-shifted impact from several oxygen lances arranged in a ring produces a circulating flow of material in the gasification zone, compensating the heterogeneity of the charge in the case of a waste gasification.

Abstract: A method of radiolabeling a protein with a radionuclide including contacting the protein with a protected tertiary thiol-containing bifunctional chelating agent that is capable of reacting with the protein at one end of the agent and is capable of complexing with a radionuclide at the other end of the agent, to form a protein-acetyl-<u>t</u>-thiol-containing conjugate. The protein-acetyl-<u>t</u>-thiol-containing conjugate then is deprotected and admixed with a reducing agent for the radionuclide, where the radionuclide is added in a subsequent step, to form a mixture of reducing agent and protein-<u>t</u>-thiol-containing conjugate. This mixture then is reacted with a radionuclide whereby the radionuclide reacts with pendant sulfhydryl groups present on the protein-<u>t</u>-thiol-containing conjugate. Methods of radioimmunotherapy and diagnostic kits suitable for forming a composition to be administered to a human patient also are disclosed.

Title: Transmit and receive loop antenna
Inventor: BOWERS JOHN H
IPC: H01Q7/04
Filed: 1996-06-03
Abstract: A transmit and receive loop antenna (10) includes a first loop element (12) coupled to an electrical circuit element for generating near fields and far fields and a shunt loop element (16) surrounding the first loop element (12) such that voltages are induced in the shunt loop element (16) by the fields generated by the first loop element (12). The shunt loop element (16) is constructed from a continuous loop of conductor to maximize current from the voltages induced in the shunt loop element. The current in the shunt loop element generates fields which largely cancel the fields generated by the first loop element in the far field. Thus, the first loop element (12) and the shunt loop element (16) establish a surveillance zone in an area proximate the loop elements.

Abstract: A method, computer program product, and data structure is provided overcome excess code development associated with developing device drivers that are hierarchically related and provides standardization to driver developers by listing in the private area of a device object types of file objects, including specific IRP handlers associated therewith, that may be created under that device object to thereby provide a device object context. In like manner, each file object has listed in the private area types of other file objects, again including specific IRP handlers associated therewith, that may be created under that particular file object to thereby provide a file object context. The default handler for a driver object points to a multiplexing function that will process an incoming IRP based on the available context information to "route" the IRP to the appropriate handler. Each file object has reference to a plurality of dispatch function references that are used by the IRP handlers to fulfill a particular request. A request to create a file object will also be validated to assure that only file objects of the appropriate type may be created in hierarchy, again according to the context information.

Abstract: The invention relates to an improved retaining and release mechanism for the magazines of automatic and/or semi-automatic firearms. A tooth (52) of lever (54) is designed to engage lateral securing slot (34) of magazine (30). The lever (54) is urged towards a body (16) of the firearm by energy exerted through a plunger (82) from a plunger spring (80) contained within the shaft (36). A base (38) is attached to the spring loaded shaft (36) located transversely in body (16) of the firearm and attached at its opposite end to an operating pushbutton (44). The tooth (52) can be disengaged from the lateral securing slot (34) by depressing either operating pushbutton (44) or slide (62). The invention's ambidextrous function can be engaged or disengaged by extending or retracting, respectively, slide (62) over locking shelves (70a, 70b). The magazine (30) can thus be released from both sides of the rifle.
