Abstract: A system and method for repeatably mounting a spray device in a desired spray position. The present technique provides the spray device with an atomizing spray section and a releasable mount. The releasable mount may be mounted releasably to a mounting member, such as a positioning system. In addition, the releasable mount may be mounted releasably to the spray device, such that the releasable mount may remain attached to the mounting member in a desired spray position. Accordingly, the spray device or its substitute may be remounted to the releasable mount in the desired spray position.

Abstract: A pneumatically operated device. The pneumatically operated device comprises a movable member disposed within a housing. The movable member is operable to control operation of the device.

Abstract: A system and method for reducing fluid drainage into air passageways of a spray device during disassembly. The present technique provides an internally mountable fluid nozzle having a fluid inlet, a fluid exit, and a converging central passageway extending substantially between the fluid inlet and the fluid exit. Accordingly, the internally mountable fluid nozzle has a relatively small internal volume, which reduces the amount of fluid that can be spilled during disassembly of the spray device. The present technique also provides a section of the spray device having an air passageway with an air exit, and a protrusive fluid passageway with a fluid exit in a protrusive offset position from the air exit. The internally mountable fluid nozzle can be mounted to the section in fluid communication with the protrusive fluid passageway, such that fluid spillage or drainage during disassembly does not flow into the air passageway.

Abstract: A pressure regulated electric pump is characterized by a positive displacement double acting reciprocating pump driven by an electric motor through a planetary roller screw. A controller senses the pressure of liquid at an outlet from the pump and varies the speed of the motor in a manner to maintain the pressure substantially constant. At a constant flow demand from the pump the motor is operated at a substantially constant speed. As flow demand rises and fans the instantaneous pump outlet pressure falls and rises. The changing pressure is sensed by the controller which makes incremental changes in the speed of the motor to cause the motor to speed up during a pressure fall and to slow down during a pressure rise, in such manner as to maintain pump outlet pressure substantially constant.

Abstract: A plural component airless spray gun for reactive liquid materials has a mix chamber into which coreactive liquid components are introduced and mixed, an airless tip at a forward outlet from the chamber from which the mixed components are emitted in a fan-shaped spray, and a mechanically operated purge rod for cleaning residual reactants from the mix chamber and airless tip. The purge rod has a main body of a diameter slightly less than that of the mix chamber and a probe at its forward end that geometrically conforms to and is adapted to enter into and clean the inside of the spray tip. During spraying the purge rod is retracted in the mix chamber rearwardly of liquid reactant inlets to the chamber. Upon completion of spraying or periodically as desired, the purge rod is moved forwardly to clean the mix chamber and the inside of the airless tip of residual reactive components.

Abstract: An agitator for a paint mix tank is characterized by a paddle that has passages in it extending between opposite sides thereof and that is reciprocated up and down in the tank to keep the paint mixed and pigments and fillers in the paint in suspension. The paddle is reciprocated in the tank in linear directions generally along paths through its passages. Reciprocation is provided by a motor operating through a gearbox, and the speed of the motor is adjustable to control the reciprocation rate of the paddle. The passages through the paddle improve its agitation performance and enable its linear speed to be sufficiently low during agitation of the paint to eliminate foaming of and entrapment of air in the paint. A process is also dislosed for mixing the liquid contents of the tank without foaming and aeration by providing the above apparatus.
