Patent number: 5656428Abstract: A system and method for homogeneous bioassay uses acoustic energy emissions. A measurement cell is designed for binding reactions of mobile biorecognition molecules. The binding reaction contained in the measurement cell is for example a ligand/receptor binding reaction or a complementary nucleic acid binding reaction. A passive acoustic energy transducer is coupled to the measurement cell for detecting acoustic energy generated by the binding reaction of mobile biorecognition molecules. The passive acoustic energy transducer generates a corresponding analog electrical signal. A signal conditioner coupled to the passive acoustic energy transducer filters and amplifies the electrical signal. A signal analyzer determines spectra of the conditioned electrical signal corresponding to characteristic acoustic energy emissions of the binding reaction of mobile biorecognition molecules.Type: GrantFiled: September 8, 1994Date of Patent: August 12, 1997Assignee: Biode, Inc.Inventors: Douglas J. McAllister, Ryszard M. Lec

Patent number: 5588357Abstract: A shock wave sterilizer for sterilizing a fluid medium, such as food, by having the fluid medium in an elastic container impacted by shock waves and expansion waves emitted from a shock wave source formed by a source of electric current discharging through an electrical conductor to vaporize the electrical conductor to produce a shock wave that is transmitted through a pressure transfer medium to the container and the fluid medium therein.Type: GrantFiled: October 25, 1994Date of Patent: December 31, 1996Assignee: Tsubakimoto Chain Co.Inventors: Hisao Tomikawa, Hideo Matsuo, Kazuhito Fujiwara

Patent number: 5466425Abstract: A system for reducing biological organisms in a liquid effluent to non-viable organic molecules that includes: a stunning chamber that applies a voltage potential across biological organisms to break cell membranes and disable the defense mechanisms of vital organisms to ultraviolet radiation; a cavitation chamber to physically destroy any remaining membranes of biologicals in the effluent that may play host to vital organisms or allow such to hide therein, the action of the stunning and cavitation chambers releasing interferons; and a molecularly implanted stimulated emitter (MISE) chamber in which high levels of ultraviolet radiation are applied to virions and spores that remain at frequencies that are readily absorbed and operate to disassociate any viable DNA and RNA strands remaining, to thereby cause "death". Prior to the stunning chamber, preferably the effluent has any large solids therein, settled, floated or filtered out.Type: GrantFiled: July 8, 1994Date of Patent: November 14, 1995Assignee: Amphion International, LimitedInventor: Billy J.

Patent number: 5419877Abstract: High temperature gas emissions from industrial power plant or environmental clean-up processes are subjected to an acoustic waveform having second harmonic content and appropriate second harmonic phase shift to impart a net acoustic Oseen force on particulate matter contained in the gas for removal of said matter. Particulate matter of 1 micron radius is positively excluded, while smaller particles are agglomerated by the sound wave. The acoustic waveform further enhances both sorption of injected sorbent particles for removal of sulfur oxides, and the efficiency of an in-line catalytic converter for removal of nitrogen oxides. The invention improves overall removal efficiency, can operate at very high temperatures, and does not produce any secondary waste, such as filters.Type: GrantFiled: September 17, 1993Date of Patent: May 30, 1995Assignee: General AtomicsInventors: Robert R. Goforth, Tihiro Ohkawa

Patent number: 5393417Abstract: The water remediation and purification apparatus includes a cavitation nozzle which is operated with a throat size and pressure drop to incur cavitation in the water. The explosive and implosive bubble growth and collapse produces free radicals which interact with contaminants in the water to oxidize the contaminants. The cavitation process is enhanced by (1) a variable throat nozzle, (2) recycling the product back through the nozzle for further oxidation, and (3) programmable control feedback. Subsequent ultraviolet radiation from high energy lamps, ion exchange and/or degassifying treatment can be employed to produce water quality within acceptable levels.Type: GrantFiled: November 15, 1993Date of Patent: February 28, 1995Inventor: Dale W. Cox

Patent number: 5245093Abstract: A process for reacting a fluid phase (gaseous and/or liquid phase) in contact with a solid phase in a reaction zone, wherein the improvement in said process comprises reacting the fluid phase in contact with the solid phase in a horizontally-oriented fluidized bed vessel. The vessel includes at least two compartments or stages, and includes means for vibrating the vessel. The process of the present invention enables one to effect fluidization of the solid phase independently of the flow rate or velocity of the fluid phase, thus enabling proper contact time of the fluid phase with the solid phase and minimizing the amount of fluid phase reactant to be recycled.Type: GrantFiled: January 26, 1989Date of Patent: September 14, 1993Assignee: ABB Lummus Crest Inc.Inventor: George Ember
