A shower plate adapted to be installed in a plasma deposition apparatus including a gas inlet port, a shower head, a reaction chamber and an exhaust duct, the shower plate being adapted to be attached to the showerhead and having: a front surface adapted to face the gas inlet port; and a rear surface opposite to the front surface, wherein the shower plate has multiple apertures each extending from the front surface to the rear surface, and wherein the shower plate further has at least one aperture extending from the front surface side of the shower plate to the exhaust duct.

A system is provided for utilizing a track for moving doors into position to be coated and subsequently removing the doors once coated.

A dry powder coating apparatus for coating pharmaceutical solid dosage forms includes a housing; a drum coater; a powder coating system; a liquid spray system; a ventilation system; a heating system; a touch screen control panel; and an operation box. The drum coater may have a truncated cone on both sides, in which one side is opened and another side is closed. The drum coater is horizontally placed inside the operation box along its axis and fixed on a rotatable shaft and a motor drives the rotatable shaft and rotates the drum coater about its own axis.

An improved mobile paint booth system and method for applying paint to a vehicle is herein disclosed. An improved mobile paint booth can comprise a plurality of vertical supports, a base support, a first upper beam, and a second upper beam. The plurality of vertical supports can comprise a corner support at each corner, and a middle support along a first wall. The base support can be substantially in the shape of a U that can connect each of the vertical supports. The base of the U can be along the bottom of the first wall. The first upper beam that can connect a first set of the corner support and the middle support. The second upper beam that can connect a second set of the corner support.

An installation for coating objects, more particularly vehicle bodies and/or vehicle body parts, having a coating booth having an air supply chamber and an application area which are spatially separated by a flow-permeable booth ceiling. An air system is set up in such a way that conditioned air can be supplied to the air supply chamber and said conditioned air flows further through the application area as booth air. In the application area, at least one application unit is arranged, wherein in the application area overspray occurs that is taken up by and carried in the booth air. The air system includes a flow guiding unit having a flow rectifier structure that is set up in such a way that the flow of the air supplied to the air supply chamber is homogenised. A method for coating objects with an installation of this kind is also provided.

A filter includes filter media and defines an inner plenum. The inner plenum has a cross-sectional dimension extending crosswise of the filter. The cross-sectional dimension decreases from adjacent the upstream side toward to downstream wall to a location disposed intermediate the upstream side and the downstream wall. The cross-sectional dimension of the inner plenum increases from adjacent the intermediate location toward the downstream wall.

The powder coating system according to the invention for coating workpieces with coating powder has a coating cubicle (3) and a cyclone separator (5), the coating cubicle (3) being connected to the cyclone separator (5) via a residual powder pipe (4). The cyclone separator (5) comprises in its inlet region an outlet tube (23) in which there is disposed a guide apparatus (50) that has multiple blades (51). These are designed so that the air vortex (28) impinging on the blades (51) can be deflected into a vertical air stream (30).
