Abstract: A robotic spray coating assembly is used in a method for spraying a coating. The assembly may include a robotic arm having a remote end region and a coating head mounted on the remote end region. The coating head emits a coating material within a defined coating delivery region via at least one first orifice located in the coating delivery region, the at least one first orifice connected to a coating supply. One or more second orifices are positioned in a pattern beyond the periphery of the coating delivery region, and a fluid supply is connected to the one or more second orifices. Fluid emitted from the one or more second orifices forms a fluid curtain that at least partially encircles the coating delivery region, thereby minimizing overspray emerging therefrom. The present invention also discloses a vehicle spray painting system and a method of spray painting a vehicle.

Abstract: In an electrostatic precipitator for filtering particulate matter from a gas, a fan (10) draws the gas (5) through an ioniser section (7) and a collector section (6). Ioniser blades (3) with sawtooth spikes (8) create a corona discharge (4) when charged to a high voltage, so that gas-borne particles are charged when passing through the corona area. The collector section (6) consists of a set of metallic plates (1, 2) of which every other plate (1) is connected to ground, while the remaining plates (2) receive a charge by induction from the ioniser blades (3), and act as repeller plates, pushing charged particles in the gas flow (5) over to the grounded plates (1).

Abstract: An apparatus for filtering particulate matter from a gas. The apparatus includes at least one tube with a substantially axially located ionizer structure, and a fan for propelling the gas through the at least one tube. The ionizer structure includes a flat blade extending axially along at least a substantial part of the tube and having a saw tooth shape with a high number of sharp teeth placed regularly along the blade edges. The blade is twisted about its own longitudinal centerline to provide rotation for a gas stream flowing along the tube.

Abstract: The present invention concerns an apparatus for filtering particulate matter from a gas. The apparatus comprises at least one tube with a substantially axially located ioniser structure, and a fan for propelling the gas through said at least one tube. The ioniser structure comprises a flat blade extending axially along at least a substantial part of the tube and having a saw tooth shape with a high number of sharp teeth placed regularly along the blade edges. The blade is twisted about its own longitudinal centreline in order to provide rotation for a gas stream flowing along said tube.
