International Classification:

B05B 5025

US Classification:

118629, 118627, 118621

Abstract:

A plurality of unconventional negative tribo-charging materials are described for use as the powder contact surfaces in tribocharging and corona powder spray guns, gun components, and powder delivery system components. The invention also provides a short barrel tribo-charging powder spray gun having an interchangeable powder contact insert and nozzle, with turbulence inducing air jets. The invention further provides novel tribocharging and corona gun designs. Improved powder coating systems are made possible wherein, for example, negative tribo guns can be utilized with negative corona guns to coat different parts of the same workpiece in a powder coating system.

US Classification:

366/273000

Abstract:

A dispensing apparatus is provided that dispenses minute quantities of liquid material, such as, for example, pharmaceutical suspensions, while maintaining substantial homogeneity of the suspension. In one embodiment, the apparatus includes a mixing device that stirs, agitates or otherwise imparts motion to the suspension that is contained in a reservoir. For example, a mixing device is realized in the form of a magnetic impeller, mixer or stirrer that is disposed within the suspension. A series of magnets external to the reservoir are rotated to produce a rotating magnetic field that induces rotation of the impeller.

US Classification:

118/309000, 427/475000, 427/180000

Abstract:

A powder coating booth containment structure including first and second canopy halves, each of which is a substantially nonconductive, seamless, structural composite to substantially reduce oversprayed powder particle adhesion to the booth inner surfaces. The composite canopy halves, when assembled into a spray booth additionally including either a floor or a utility base and one or a pair of end units in the form of aperture bulkheads, vestibules, or a combination of both, are structurally sufficiently strong that no external support frame is required. The composite canopy halves can each include sidewall and ceiling portions, in an embodiment, that can be connected to a floor. In another embodiment, the canopy halves each additionally include a floor portion such that they may be connected together at a floor edge and placed atop a utility base. They may be connected to the utility base. In another embodiment, the canopy halves may each further include an integral end or ends, comprising aperture bulkhead or vestibule-type end portions. Methods of assembling these embodiments are also provided that require less time than for known powder coating spray booth assembly. In another embodiment, a conductive material is incorporated into the composite structure to bleed off charge or repel like charged particles generated during or after a spraying operation.
