Abstract: A method for producing multilamellar coalescence vesicles (MLCVs) containing increased amounts of biologically active compound is disclosed. The method involves hydrating at least one powdered lipid in an aqueous buffer at a temperature above the phase transition temperature of the highest melting lipid to form multilamellar vesicles, reducing the size of the multilamellar vesicles to about 20-400 nm to produce small unilamellar vesicles (SUVs) or large unilamelar vesicles (LUVs) or a mixture thereof, and incubating the SUVs, LUVs or mixture thereof with a biologically active compound in in aqueous solution under sufficient conditions to form MLCVs containing the biologically active compound without the use of an organic solvent, a freeze-thawing step or a dehydration step MLCVs produced by this method contain increased amounts of biologically active compound over prior art liposomes produced with an organic solvent, a freeze-thawing step or a dehydration step and fewer vesicles are substantially free of biologically active compound

Patent CA-2317180-C (CA)
Inventor: BALDI ALPHONSO L
IPC: B22F1/00
Filed: 1990-09-13
Granted: 2005-11-15
Abstract: Coating with high-melting metals can be simplified by alloying high-melting metal with sufficient aluminum to make low-melting alloy that is applied, bonded in place, and then subjected to the leaching out of some or most of the aluminum.      The resulting surface is porous and will receive and hold top coatings. Leached surface can be pyrophoric and top coating can be exothermically combustible. Pyrophoric powder can also be coated on boron or carbon fibers or sintered with combustible particles. Porosity can be created by subjecting workpiece to diffusion conditions in contact with depleting material such as powdered nickel or high-nickel aluminides or cobalt or high-cobalt aluminides. Aluminum particles can be electrophoretically deposited on foil and then diffused in.    Leaching aluminum out with caustic is improved when a little H2O2 is present in the caustic. Subsequent treatment of the leached surface with weak acid further improves pyrophoricity, and folding of the pyrophoric member extends its pyrophorically-generated high temperature dwell. Resin foil containing pyrophoric particles makes effective decoy.

Granted: 2007-09-25
Abstract: Disclosed is a process for the treatment of a plant fluid effluent containing odor compounds including an alkyl mercaptan or an alkyl thiol, an amine compound, ammonia, hydrogen sulfide and mixtures thereof by contacting the plant effluent in either a counterflow or cocurrent flow process. In the process, the effluent is contacted with an aqueous solution comprising a peracid compound and optionally an essential oil. When contacted with the peracid, odor compounds in the effluent are oxidized and converted from the gaseous phase into a chemically modified highly aqueous soluble phase in the aqueous treatment. In this way, odor removal from the gas is preferred and odor compounds are efficiently transferred into the aqueous treatment solution. The use of such a process produces a significant improvement in odor quality index as measured by a conventional process using an expert panel when compared to conventional treatment methods.

Title: Signal enhancement for voice coding
Inventor: MCARTHUR DEAN
IPC: G10L19/02
Filed: 2000-11-24
Granted: 2006-05-30
Abstract: An adaptive noise suppression system includes an input AID converter, an analyzer, a filter, and a output D/A converter. The analyzer includes both feed-forward and feedback signal paths that allow it to compute a filtering coefficient, which is input to the filter. In these paths, feed-forward signal are processed by a signal to noise ratio estimator, a normalized coherence estimator, and a coherence mask. Also, feedback signals are processed by a auditory mask estimator. These two signal paths are coupled together via a noise suppression filter estimator. A method according to the present invention includes active signal processing to preserve speech-like signals and suppress incoherent noise signals. After a signal is processed in the feed-forward and feedback paths, the noise suppression filter estimator then outputs.a filtering coefficient signal to the filter for filtering the noise out of the speech and noise digital signal.

Title: Bone anchor and deployment device therefor
Inventor: NICHOLSON JAMES
IPC: A61B17/56
Filed: 1999-05-27
Granted: 2008-01-15
Abstract: A rivet-like bone anchor has a floating washer at its head that can adapt to an angled bone surface and, thereby, better secure a tissue thereto. The anchor includes a rivet, an expandable sleeve, and a washer. The rivet includes a head and an elongate body having proximal and distal ends, the head being mounted on the proximal end of the elongate body. The expandable sleeve has an inner bore adapted to receive the rivet body. The washer "floats" at a proximal end of the sleeve. As the rivet is inserted into sleeve, the sleeve expands into an interference fit with the bone. The head of the rivet, moreover, forces the floating washer into contact with the tissue at an angle that conforms to that of the underlying bone surface. A deployment tool permits the anchor to be deployed without application of unnecessary counterforce. The tool includes an outer tube, the distal end of which can hold the anchor housing, e.g., via a screw fit. A rod, which is slidably disposed within the bore of the, tube, can be used to push the rivet into the expandable sleeve so that the sleeve expands into the bone, so that the floating washer is forced into position against the bone surface, and so that anchor is broken away from the housing. This can be effected, for example, by squeezing the distal ends of the outer tube and the rod together, e.g., in the manner that the end of a syringe is squeezed.

Abstract: L'invention concerne un support de catalyseur désaluminé, un procédé pour produire ledit support de catalyseur avec une teneur réduite en aluminium à base de phyllosilicates courants, tels que la montmorillonite, ainsi qu'un procédé d'hydratation d'oléfines C2 ou C3, où l'on utilise le support de catalyseur à teneur réduite en aluminium. Pour la réaction d'hydratation à catalyse acide, le support est imprégné d'acide phosphorique. L'amélioration qui caractérise l'invention comparativement au procédé d'hydratation classique consiste dans le fait qu'il ne peut plus se produire de lixiviation d'aluminium du support en présence d'acide phosphorique. Les phénomènes de blocage par phosphate d'aluminium intervenant dans les appareils intercalés après la réaction ne sont plus à craindre.

Abstract: A vent valve insert comprises a bushing assembly, a piston assembly and a spring. It is designed to fit snugly and sealingly within a suitable borehole, such as the vent borehole of an ECP manifold assembly. The bushing assembly defines a longitudinal bore within which the piston assembly is situated. When pilot pressure is applied to its top surface, the piston assembly is forced to an open position wherein fluid is allowed to flow through the vent valve insert. Absent pilot pressure acting against the top surface, the spring acts to force the piston assembly upward within the longitudinal bore. Secured to the bottom portion of the piston assembly, an annular sealing member is carried upward so than its flat surface seats against: a raised inner portion of an annular valve seat. The vent valve insert is thus normally biased to the closed position. The vent valve insert also features a mechanism for preventing non-longitudinal movement of the piston assembly as it is moved longitudinally within the longitudinal bore. The mechanism not only guides the movement of the piston assembly within the bushing assembly but also prevents the bell clapper effect inherent to the vent valve inserts currently used in the industry.
