According to the method of the present invention, a product is introduced into the product chambers, where the product is held while a substance is filtered from the product through the porous walls and the product is dried by reducing the pressure in the vacuum chambers and the product chambers.Type: ApplicationFiled: November 26, 2002Publication date: May 27, 2004Applicant: Alkermes Controlled Therapeutics, Inc.Inventors: Paul F. Herbert, Douglas M. Bissonnette, Gregory C. Troiano

Patent number: 6736965Abstract: An auxiliary oil filtration system and method for filtering oil in an engine is provided. The auxiliary oil filtration system consists of an auxiliary filtration device, an integral oil transfer pump controlled by an electric motor and that is in electrical communication with an electrical control unit, an electronic pressure sensor, fluid conductors, and means for connecting hardware. The auxiliary filtration device is separate from the primary engine lubrication system, and includes a media supply reel having a roll of filtering media thereon which is moveable to a take-up reel. A media indexing system advances the media supply reel as the filtering media becomes plugged. An electronic pressure sensor dictates the advancement of the filtering media when a pre-determined differential pressure across the filtering media is attained. When all of the filtering media has been transferred from the supply reel to the take-up reel, the cartridge is replaced.Type: GrantFiled: April 24, 2002Date of Patent: May 18, 2004Assignee: Engineered Machined Products, Inc.Inventors: Jason M. Cousineau, David J. Allen

Publication number: 20040035805Abstract: A contaminant-flushing machine for removing contaminants from a container, such as an engine transmission, air-conditioner coil, or transmission cooler, which includes hoses for coupling to the transmission cooler and a pump for circulating fluid through the hoses and the transmission cooler, and a fluid filter having a reduced tendency towards causing vaporization of the fluid. Also included in the contaminant-flushing machine is an automatic aeration system for injecting air into the circulating fluid at predetermined intervals. Additionally, a reverse flow piping circuit is included to permit automatic and electric manipulation of the flow direction of fluid through said transmission cooler while at the same time not altering the direction of flow of fluid through the pump.Type: ApplicationFiled: August 21, 2002Publication date: February 26, 2004Inventor: Dennis B. Hansen

Publication number: 20040026339Abstract: A filtration assembly for filtering polymer fluids at varying flow rates includes at least two filter housing assemblies releasably attached to a filter support or main block. Polymer fluid is delivered to the filter housing assemblies via an inlet passage in the main block, and filtered polymer fluid is transported from the filter housing assemblies to an outlet passage in the main block. One end of each filter housing assembly is attached to the main block and includes an inlet port for receiving polymer fluid from the inlet passage and an outlet port for delivering filtered polymer fluid to the outlet passage. A single valve disposed on the main block selectively alternates fluid flow between the main block and each filter housing assembly.Type: ApplicationFiled: July 10, 2003Publication date: February 12, 2004Inventor: William H. Hills

Publication number: 20040011730Abstract: A device for reducing the liquid content of a liquid and solid slurry. In the device, a dual-walled vertical tube sits atop a perforated endplate. The wall of the tube is non-porous at the upper end and porous at the bottom end. A liquid and solid slurry enters at the top of the tube filling the tube. Some of the liquid in the slurry exits the tube by radial outflow through the porous segment of the tube wall. The reduced liquid slurry exits through the perforated endplate.Type: ApplicationFiled: July 18, 2002Publication date: January 22, 2004Inventors: James R. Powell, Morris Reich
