Title: Novel stable aqueous solutions of tetrahydro and hexahydro iso-alpha acids
Inventor: GUZINSKI JAMES A
IPC: C12C3/00
Filed: 1993-05-06
Abstract: New stable, concentrated aqueous solutions of tetra-hydro iso-alpha acid (THIA) and hexahydro iso-alpha acid (HHIA) are disclosed. These solutions depend upon the presence of a second kind of iso-alpha acid to increase the solubility of both iso-alpha acids to a point outside of the ranges of their normal solubilities... in the case of THIA and HHIA, to a point above their solubility ranges and, in the case of unreduced iso-alpha acid (UIA) and dihydro iso-alpha acid (DHIA), to a point below their commercial prior-art solubility ranges. This "inversion" of solubility and stability behavior in water, which requires the presence of two different kinds of iso-alpha acids, is new to the art, and provides a novel approach for making commercially- desirable concentrates of THIA and HHIA available to the brewer.

Title: Rectifying dialyzer, membrane and process
Inventor: OFSTHUN NORMA J
IPC: B01D63/02
Filed: 1993-01-08
Abstract: The invention provides dual-skinned membranes useful as one way or rectifying membranes which reduce back filtration of solute molecules in dialysis and which improve nutrient supply and product recovery in membrane bioreactors. The membranes are dual-skinned polymeric materials preferably in the form of hollow fibers. The membranes have skins of polymer on the opposite sides with differing porosity or sieving coefficient characteristics. The membranes are formed by extruding a polymer dissolved in a solvent while contacting at least one surface with a non-solvent which is miscible with the solvent. The other surface is contacted with a non-solvent. The two non-solvents are either different from each other or one of the non-solvents contains a soluble additive which changes the porosity of the skin formed on the dissolved extruded polymer. Improved dialysis devices are formed by using bundles of the hollow fiber membranes as a dialysis means having rectifying properties. Improved bioreactors are formed by using bundles of hollow fiber membranes as a growth vessel having rectifying properties.

Title: An aqueous and petroleum gel method for preventing water-influx
Inventor: PHELPS CRAIG H
IPC: C09K8/50
Filed: 1992-05-15
Abstract: A method to prevent damage to a water-sensitive hydrocarbonaceous fluid-producing zone (14) of a formation (10) which is penetrated by a well (12) which has a water-influx problem. A gellable petroleum mixture is injected into the well where it forms a solid hydrophobic gel in situ sufficient to temporarily close pores in the water-sensitive zone. The mixture is allowed to remain in the water-sensitive zone (14) for a time sufficient to form a solid gel so as to preclude fluid entry into the water-sensitive zone (14). Afterwards, an aqueous based gel mixture is injected into the water-influx zone (16) where it forms a solid hydrophilic gel which is substantially stable thereby precluding fluid entry into the well. Subsequently, the solid petroleum gel degrades at formation conditions and opens the water-sensitive zone (14) to production of hydrocarbonaceous fluids. Thereafter, substantially water-free hydrocarbonaceous fluids are produced from the water-sensitive zone (14).

Title: High-cycle regenerative heat exchanger
Inventor: TANAKA RYOICHI
IPC: F28D19/04
Filed: 1994-01-18
Abstract: ABSTRACT        A high-cycle regenerative combustion system has first and second regenerative heat exchanger units.   A four-way valve is provided for alternately bringing the heat exchanger units into contact with a low temperature fluid and a high temperature fluid. The valve is switched at a switching cycle time not longer than 60 seconds.  Each heat exchanger unit has a void ratio  e which substantially provides the maximum value (Q/V)max of the volumetric efficiency (QVV).  The temperature efficiency ? t is preset to be a value in a range between 0.7 and 1Ø  The heat transmission coefficient h  and the heat transmission area A of the heat exchanger unit are determined such that the temperature efficiency, which is calculated in accordance with a specific equation as being a function of the heat transmission coefficient, the heat transmission area and the switching cycle time ?, falls under the preset value within the range mentioned above.  Each of the first and second heat exchanger units has the cell pitch P and the cell wall thickness b, which provide the above-mentioned values of the void ratio, heat transmission coefficient and heat transmission area.  Thus, a compact and high-performance regenerative heat exchanger can be obtained, which has a reduced overall volume while exhibiting the large heat transmission rate and high temperature efficiency.

Title: Device and method for sleeving the inside surface of tubular members
Inventor: KOZAK LARRY M
IPC: B23P19/02
Filed: 1994-05-25
Abstract: ABSTRACT OF THE DISCLOSURE Device and method for sleeving an inside surface of a tubular member, which tubular member may be a heat transfer tube of the kind typically found in nuclear steam generators.  The device comprises a sleeve having a wall forming a compact spiral-shaped transverse cross section defining a first position of the sleeve.  The wall in its first position surrounds an expandable bladder supported by a support body.  The support body, bladder and sleeve are inserted into the tube and translated along the inside surface thereof to the region of the tube to be sleeved. The compact spiral-shape of the wall in its first position allows it to pass unimpeded through the inside diameter of a previously installed sleeve that may be disposed in the tube,  so that the previously installed sleeve does not interfere with the translation of the sleeve along the inside surface of the tube.  Connected to the bladder is a pressurizer for  pressurizing  the  bladder  so that  the bladder expands to expand the wall of the sleeve (after it passes  through  the  inside  diameter  of the  previously installed sleeve) from the first position to a second posi-tion wherein the wall forms an annular transverse cross section.  A fluid reservoir is in fluid communication with the pressurizer for supplying fluid to the pressurizer which  in turn pressurizes the  fluid  and supplies the pressurized fluid to the bladder to pressurize and expand the bladder.  As the bladder expands, the wall moves from its first position to its second position and intimately engages the inside surface of the tube for sleeving the inside surface of the tube. The sleeve may then be welded to the tube to ensure that the sleeve is affixed to the tube.

Inventor: COPPER CHARLES M
IPC: A23G4/20
Filed: 1992-12-14
Abstract: An improved method of combining active ingredients with polyvinyl acetate for use in chewing-gum results in significantly less degradation of the active ingredients. After the polyvinyl acetate and one or more active ingredients have been mixed together in an extruder, the mixture is extruded through a die to form a sheet-like extrudate (32). The sheet like extrudate is then cooled using a series of three chilled compression rolls (12, 14 and 16). The extrudate is pinched between adjacent chilled compression rolls and both surfaces of the extrudate maintain contact with at least one of the chilled compression rolls for a period of time. The extrudate is thereby cooled swiftly and thoroughly, resulting in reduced degradation of the active ingredients.
