Patent number: 6378383Abstract: An apparatus for measuring tensile and bending forces applied to a fat-line towed-array. Tension sensors are configured within a modified fat-line towed-array bulkhead to measure axial tension applied to the front of the fat-line towed-array, while bending sensors mounted further downstream along the fat-line canister interior walls, measure the bending load. The sensor outputs are encoded and digitized before transmitted through a tow line for further data conditioning and processing. The tension and bending sensor data provide information to evaluate the force exerted on the towed-array, allowing a measure of the deployment capability. Measurements taken at various fluid flow rates provide data regarding deployment effectiveness.Type: GrantFiled: June 12, 2000Date of Patent: April 30, 2002Assignee: The United States of America as represented by the Secretary of the NavyInventors: An-Keun Peter Lee, Michael R.

Patent number: 6174431Abstract: A method for pretreating and re-refining used oil that requires only moderate heat and only one re-refining step. The pretreatment involves mixing the used oil with a basic solution and optionally a phase transfer catalyst. The phase transfer catalyst aids the chemical reaction which allows removal of impurities in used oil. The basic solution preferably includes more than one base. The used oil, basic solution and phase transfer catalyst are mixed under low heat. The pretreated oil is then mixed with liquid propane in a non-turbulent manner, such as by use of a globe valve or orbit valve. The mixture of used oil and liquid propane are then placed into an extraction vessel and impurities are allowed to settle out of the oil and propane mixture. Heavy fraction may be removed from the extraction vessel. Preferably, a second vessel called a settling vessel will be used to cause further settling of impurities out of the used oil. Light fraction is produced which may be re-refined to produce base oil.Type: GrantFiled: May 26, 1999Date of Patent: January 16, 2001Assignee: Interline Hydrocarbon, Inc.Inventors: Michael R. Williams, Jan Krzykawski

Patent number: 5612226Abstract: A gas/liquid contact method and apparatus, for example, for oxygenating blood using O.sub.2 and O.sub.3. A low pressure stream of oxygen is introduced into a chamber through a spray orifice while inducing blood into the oxygen stream in a first blood/oxygen contact zone. The blood is caused to issue from the spray orifice as a dispersed low-pressure spray of blood droplets and is directed against a dome-shaped film forming surface located within the chamber in the path of spray. The droplets impinge on the surface at relatively low velocity and form a film for providing a further oxygen/blood contact zone. The apparatus may be designed to operate on a one-pass or a recirculation basis.Type: GrantFiled: October 3, 1995Date of Patent: March 18, 1997Assignee: LifeTech CorporationInventor: Michael R.
