TL;DR: In this article, a powder spray booth defines a controlled area within which to apply powder coating material onto the vehicle bodies, a powder kitchen located at a remote position from the booth, and a number of feed hoppers located proximate the booth which receive powder coating materials from the powder kitchen and supply it to automatically or manually manipulated powder spray guns associated with the booth.

TL;DR: In this paper, a rotary distributor with a non-rotating flow tube and a gap between it and the spindle of a rotatable spindle is shown to provide rotary seal between the tube and spindle.

TL;DR: In this paper, a powder spray gun is mounted in the open forward end of a barrel and includes a sleeve (46) located on the centre axis of the barrel for directing a flow of a pressurised gas, e.g. air, through the center of the nozzle assembly, a nozzle (58) surrounding the sleeve defining an annular flow path for powder spray coating material encircling the flow of pressurized air and an air deflector cap (64) for directing the pressurisation air radially outwardly and into the flow being emitted from the nozzle

TL;DR: An electrostatic powder coating system for selectively spraying any one of a plurality of different pulverant powder materials from a common spray gun without the necessity for physically disconnecting or reconnecting the spray source of the different powder materials to the common gun is described in this paper.

TL;DR: An apparatus for applying powder coating material onto large objects such as automotive, truck or other vehicle bodies as mentioned in this paper includes a powder spray booth (12) defining a controlled area within which to apply powder coating materials onto the vehicle bodies.
