Patent CA-2163685-A1 (CA)
Title: Valve controlled by fluid
Inventor: BUFFET JEAN CLAUDE
IPC: F16K31/08
Filed: 1995-11-24
Abstract: A permanent magnet actuated pilot operated valve having a central permanent magnet disposed within an annular axially polarized magnet. The annular magnet is attached to a pressure responsive membrane moveably responsive to a fluid pressure control signal. Movement of the annular permanent magnet effects movement of the central magnet, either by attraction or repulsion depending on whether like or opposite poling is employed. Movement of the central magnet effects opening of a pilot valve which creates a pressure differential which in turn causes a second pressure responsive membrane to move and effect opening of a main valve. Change in the fluid pressure control signal causes the annular magnet to return to its original position thereby effecting reverse movement of the central magnet and closure of the pilot valve. A bleed hole causes pressure equalization across the second membrane and reclosure of the main valve.
Patent CA-2164348-A1 (CA)
Inventor: ABDIEV MAKSOUT AKHAJANOVICH
IPC: C02F1/46
Filed: 1995-12-04
Abstract: A method and apparatus for the treatment of industrial and municipal waste waters is disclosed which utilizes electro-conductive properties in conjunction with the introduction of an electric current to render harmless and/or manageable in a very cost-effective manner the undesirable contaminants in industrial, including nuclear, and municipal waste fluids. The above flow will be passed through a hollow truncated-conic refractory electro-conductive movable-along-the-flow electrode connected with a ground and at a distance there is situated an identical electrode but connected via several electrical apparatuses with a terminal of an alternating high-voltage energy source. When the electrodes are moved along the flow, i.e. closer together or further apart,  they change the electric density in it and thus the intensity of direct-cycle steam from a flow. In the presence of an electric arc (maximum current) in a flow, there is total disintegration of a flow. In this case under the influence of an arc's high temperature and ambient air, simultaneously in the flow the fuel-organic content is burnt out, the mineral content is crystallized, the water content is turned into steam, the hazardous and toxic contaminates are thermal degraded, pathogens and microorganisms are sterilized and there is a precipitation of crystalline residue. Together the whole of this, except the residue, form a vapour-flow of smoke, mist, minute crystals, metal ions, steam, water droplets, etc. This flow being sucked up is introduced into a cyclone where the separated smoke is directed to a stack and the remaining flow passing into the cyclone's lower part through a wire mesh packed layer and a porous membrane where the flow is subjected to the separation of its constituents, i.e. the contaminants are direct back to a sewage system and the water steam will be cooled further on, ready for use. When this method for treatment is adopted in plants for disposal of waste water produced from a nuclear power station and any other industrial plant or a municipal sewage treatment plant, for instance, an evaporator is simplified, various tanks and incinerator are dispensed with and thus the plants for the disposals can be simplified to a large extent.

Title: Eddy current separator
Inventor: WELLS RANO R II
IPC: B03C1/247
Filed: 1996-03-05
Abstract: The disclosed eddy-current separator has several new features.  One includes a magnet assembly which is metal-sleeved for protecting the magnets from impact by particles or objects piercing the waste-carrying conveyor belt with which the separator is used.  A low-rotating-speed epoxy-layered shell surrounds the sleeve for additional protection.  A conveying extension carries ferrous "fines" from the conveyor into the receptacle used to collect waste from which non-ferrous material has been separated.  Such extension permits such fines to be under the substantial influence of the magnet assembly over an arc well less than 180°.  The conveyor belt uses relatively-closely-spaced cleats of reduced height to reduce the "loading" of an individual cleat with potentially-piercing ferrous fines.  A two pole magnet assembly may be used and/or a magnet assembly in which the magnet pole faces are curved for air gap reduction.

Title: Method of transmitting a biologically active material to a cell
Inventor: WALLACH DONALD F H
IPC: A61K48/00
Filed: 1994-12-15
Abstract: A method for transmitting a biolog-ically active material to a cell is provided. The method involves encapsulating the ma-terial to be transmitted in a pancilamel-lar non-phospholipid carrier vesicle which does not lyse cells upon fusion with cells, delivering the carrier vesicle to a location proximate to the cell, allowing the non-phospholipid bilayer of the carrier vesicle to fuse with the membrane of the cell and al-lowing the encapsulated material to diffuse into the cell. The method can be used to transmit a variety of biologically active ma-terials to cells either in vivo or in vivo. The method provides a means for transmitting a biologically active material directly to the cytoplasm of a cell. Upon fusion with a cell, material associated with the bilayers of the non-phospholipid vesicle becomes in-corporated into the outer membrane of the cell. Accordingly, a method for transmit-ting bilayer-associated material to a cell is also provided.
