Patent number: 7740398Abstract: A dynamic mixer includes a housing structure having a mixing chamber, having an inlet opening through which a material or materials to be mixed is passed into the mixing chamber and an outlet. A mixer rod has mixing rod portion disposed in the housing structure and a plurality of mixing paddle portions each having a mixing surface. The mixing rod is adapted for attachment to a drive unit which imparts a rotational mixing force to the rod. In one exemplary non-limiting embodiment of a mixer, the housing structure includes a hollow tubular structure with first and second open ends, a hollow T fitting having a first opening attached to the first end of the hollow tubular structure, a second opening opposed to and in alignment with the first opening and a third opening transverse to the first and second openings, and a coupler fitting attached to the second open end of the tubular structure.Type: GrantFiled: October 4, 2006Date of Patent: June 22, 2010Assignee: Fluid Research CorporationInventors: David J. Cline, Truc S. Tang, Richard T. Naruo, Stephen P. Gordon

Patent number: 6913166Abstract: A system for metering and dispensing single and plural component liquids and solids as described herein. The dispensing system has a microprocessor-based control system and progressive cavity pumps which provide a very accurate control of component ratios, shot sizes, flow rates and dispense durations. The system has numerous feedback components for accurately controlling the pressure, flow rates, fluid levels and amounts of fluids dispensed. Where a valved nozzle is used, the pressure in the flow system is used to control the pumps rather than the valve. Such a system may be used as a sprayer with compressed air added. Drum rams are associated with the supply drums and the progressive cavity pumps may be placed on the drum ram. Maintenance of a steady state in the system is accomplished with back and forth movement of the pump, with compensation for pressure changes. Absolute rotational position of the pump can be monitored when a set pressure is maintained, to diagnose system conditions.Type: GrantFiled: November 20, 2003Date of Patent: July 5, 2005Assignee: Fluid ResearchInventors: David J. Cline, Timothy S. Clark, Stephen P. Gordon, Michael R. Engle

Publication number: 20020162857Abstract: A dispensing system including a housing with an interior bulkhead and four progressive cavity pumps mounted within the housing on one side of the bulkhead. The pumps are mounted with the bores in vertical orientation. Gear boxes including bevel gears coupling the vertically mounted pumps with horizontally mounted motors located on the other side of the interior bulkhead. A dispensing head is located above the housing with outlet passages extending from the motors to the dispensing head defining a path to the dispensing head which is continuously upward. The dispensing head includes valves driven by a pneumatic cylinder. A solenoid controls flow of pressurized air to the pneumatic cylinder from a position adjacent the dispensing head on the boom supporting both.Type: ApplicationFiled: June 18, 2002Publication date: November 7, 2002Applicant: FLUID RESEARCH CORPORATIONInventors: David J.

Patent number: 6286566Abstract: A system for metering and dispensing single and plural component liquids and solids as described herein. The dispensing system has a microprocessor-based control system and volumetrically efficient non-reciprocating pumps which provide a very accurate control of component ratios, shot sizes, flow rates and dispense durations. The dispensing system maintains constant pressure between the output of the pump and the dispense head. The progressive cavity pump is formed from individual, interlocking pressure sections, each of which has a double helix bore. A rotor is inserted into the double helix bore with an interference fit. The dispense head has no dynamic fluid sealing surfaces and instead uses bellows as a sealing mechanism. The dispensing system includes a simple, easy to use calibration procedure and a weight scale.Type: GrantFiled: October 3, 2000Date of Patent: September 11, 2001Assignee: Fluid Research CorporationInventors: David J.
