An extruder includes a receptacle for containing material to be extruded. The extruder further includes a dispersion blade positioned within the receptacle and a nozzle secured to the receptacle. The nozzle defines a first opening positioned within an interior of the receptacle, defines a second opening positioned outside of the receptacle and defines a channel which extends from the first opening through the nozzle to the second opening defining a flow path which extends from the first opening, through the channel and to the second opening. The nozzle extends through a wall of the receptacle and into the interior of the receptacle such that the first opening is positioned spaced apart from the wall.

An agitator includes a central shaft, a radially spaced array of vanes and a shroud encircling the central shaft so as to intersect the vanes perpendicular to the vanes' depth and along their length, thus defining an inner passageway between the shroud and the central shaft and an outer passageway between the vanes, radially extending outwardly of the shroud.

A paint circulation system includes: a main line; a branch line; a supply pump; and a pressurization device for storing pressure of the paint in a high-pressure state in which the pressure of the paint is higher than a predetermined pressure, and for applying pressure to the paint inside of the branch line in a low-pressure state in which the pressure of the paint is lower than the predetermined pressure, in which sedimentation of the paint is prevented by driving the supply pump so that the high-pressure state and the low-pressure state occur, to cause flow sending the paint inside of the branch line from a side of the painting device to a side of the main line using a pressure difference between the predetermined pressure in the low-pressure state and the pressure of the paint.

Apparatus for dispensing a plurality of fluids, comprising a plurality of fluid containers and a carrier on which a plurality of pumps is mounted. Each one of said plurality of fluid containers is releasably connectable to an associated pump of said plurality of pumps via a connector assembly thereby forming a fluid connection between the fluid container and the associated pump. The connector assembly comprising a first connector to the associated pump and a mating second connector to the respective fluid container and wherein at least one of said plurality of fluid containers comprises a refill opening for refilling the fluid container.

Described herein is a device comprising a liquid container mounting structure and a support structure. The liquid container mounting structure securely holds liquid storage containers. The liquid container mounting structure is movably mounted to the support structure. The liquid container mounting structure may be configured to move the liquid container mounting structure relative to the support and/or include a crank handle or motor, such as an electric motor. The liquid container mounting structure is removable from the support structure to allow for reconfiguration and/or transport of the liquid container mounting structure.

A pump assembly and components therefor including an impeller which has flow inducer elements on an inner surface of a front shroud thereof, a flow directing device or strainer having passageways for delivering material to the impeller and at least one flow circulating passageway and a pump casing having an intake section with flow distribution vanes in the region of a feed opening adjacent the intake section.

A method and apparatus for forming an aerosol. An apparatus may comprise an inner chamber, an outer chamber located around the inner chamber, and a wave generating device associated with the outer chamber. The inner chamber may be configured to hold a mixture that is to be converted into an aerosol within the inner chamber. The outer chamber may be configured to hold a fluid. The wave generating device may be configured to generate waves that propagate through the fluid into the mixture to stir the mixture.

An externally mounted tank nozzle assembly which can be used in many mixing systems. The assembly can be installed as a fixed nozzle or as an externally adjustable nozzle. The disclosed nozzle is light-weight, corrosion-resistant as well as abrasion-resistant to withstand many tank mixing environments and conditions.
