Patent number: 7514256Abstract: A diffusion controlling bioreactor that selectively controls the molecular diffusion between fluids through a microchannel in fluid communication with a reaction reservoir. The length and cross-sectional area are selected to obtain a predetermined rate of molecular diffusion between fluids. When the fluids are liquids, flow through the microchannel is laminar and the capillary action of the microchannel and fluid is such that the fluid does not flow into the reaction reservoir unless the pressure of the fluid is increased by an external source, thereby minimizing contamination of the bioreactor. The instant invention may also utilize at least one microchannel and reagent reservoir to regulate, rather than prevent, the passage of various molecules into the bioreactor. A pressure equalizing vent operating on similar principles to the microchannel may have a structure configured to minimize the chances of fluid leakage from the bioreactor, even if the bioreactor is turned in various directions.Type: GrantFiled: February 11, 2005Date of Patent: April 7, 2009Inventor: Emilio Barbera-Guillem

Publication number: 20080053919Abstract: A filter assembly is provided that includes an immobilized base material in combination with a slow release mechanism for introducing an additive base material into a lubrication fluid flowing through the filter assembly. The introduced base material is a weaker base material than the base material of the immobilized base material. The combination of the immobilized base material and the additive base material provides a system that would work to neutralize acids for all lube formulations commonly used in the field. As a result, oil drain intervals can be extended.Type: ApplicationFiled: August 31, 2006Publication date: March 6, 2008Applicant: CUMMINS FILTRATION IP, INC.Inventors: Harold R. Martin, Wilson Lee Currier

Patent number: 7316778Abstract: An improved oil conditioning filter, for use with an internal combustion engine, includes a mechanically active filter element and a chemically active filter element having a reactive basic conditioner therein. The reactive basic conditioner is provided to counteract acidic combustion products in lubricating oil in an internal combustion engine. In a preferred embodiment of the invention, the chemically active conditioning agent is provided in a plurality of pellets disposed within the oil filter housing. The pellets may be bonded together to form an integral porous filter element having spaces defined between the pellets thereof. The pellets are made of a mixture including a polymeric binder and the chemically active conditioning agent, in a defined weight ratio and in a narrow range of particle sizes. The chemically active filter element reacts with acids present in the oil to form a product which may be filtered out of the oil. The pellets are made either by a hot extrusion process or by a solvent process.Type: GrantFiled: January 26, 2004Date of Patent: January 8, 2008Assignee: Honeywell International, Inc.Inventors: Ronald Paul Rohrbach, Gordon William Jones, Peter D. Unger, Daniel E. Bause, Lixin L. Xue, Greg Kemenah
