Abstract: 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.

Abstract: 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.

Abstract: 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.
