Patent number: 7754488Abstract: The invention relates to a method to analyze the condition of a functional fluid comprising: (1) obtaining a sample of the used fluid; (2) placing the sample of the fluid to a test medium; (3) reacting the fluid with an indicator in the test medium; (4) analyzing visually the results of the reactor resulting in the determination of the condition of the fluid. Further an apparatus for analyzing functional fluids is disclosed in the form of a test medium consisting of an absorbent or nonabsorbent material which has been treated with a chemical indicator, marker substance or a developer or detector reagent upon which a sample of the fluid to be tested is placed. The components in the treated test medium react with components in the test fluid providing a visual indication, for example a color change, to judge the condition, the presence of a marker substance or another parameter of the fluid.Type: GrantFiled: April 13, 2004Date of Patent: July 13, 2010Assignee: The Lubrizol CorporationInventors: Robert C.

Patent number: 7540081Abstract: A thermally conductive material is provided as a mixture of a silicone, a ceramic powder, and a curing catalyst. The material may be pre-formed into a pad and each side of the film protected with removable release layers. Each side of the film may also include a coating of an adhesive material that aids in coupling the interface film with a surface. The material may alternatively be produced in a screen-printable paste. As such, a layer of the paste may be screen-printed on a surface as complete sheet form or as a patterned film by using a stencil patterned screen mesh. The interface material is sandwiched between a printed circuit board and a heat sink to form the circuit board assembly. In a multi-step press process, the assembly is cured and a laminate formed. The assembly process may also include a priming function that prepares metal surfaces of the circuit board and heat sink for receiving the interface material.Type: GrantFiled: November 7, 2006Date of Patent: June 2, 2009Assignee: American Standard CircuitsInventors: Sundaram Nand Kumar, Gary Garvin Sites, Bhavik Patel

Patent number: 6412338Abstract: A viscometer for sensing or characterizing the stress required to shear a fluid at a given rate includes a pair of members coaxially mounted for relative rotation. Between the members is an annular gap defining a flow path for the fluid. The flow path is configured such that during differential rotation of the members, fluid is caused to flow through the annular gap that is a function of the differential rotation and the viscosity of the fluid. A sensor measures the torque or torque equivalent required to achieve such differential rotation between the members.Type: GrantFiled: November 29, 2000Date of Patent: July 2, 2002Assignee: The Lubrizol CorporationInventors: Frederick P.

Patent number: 5964318Abstract: A system for measuring the quality and level of lubricant in an engine lubricant reservoir includes a valve for selectively directing a portion of lubricant from the engine through a first conduit for return to the engine or through a second conduit for removal from the engine. Within the first conduit are one or more sensors for sensing the condition of the lubricant passing through the first conduit. The sensors are monitored by a controller which is operative selectively to cause the valve to block the flow of lubricant through the first conduit and direct a portion of the lubricant through the second conduit based on the monitored conditions of the lubricant. Also, the controller directs a supply of fresh lubricant to the engine in response to the lubricant in the engine lubricant reservoir dropping below a predetermined level.Type: GrantFiled: January 12, 1998Date of Patent: October 12, 1999Assignee: The Lubrizol CorporationInventors: Frederick P.
