Abstract: A powder facility used for spray coating includes at least one injection unit (6), at least two powder stations (2) and at least one cleaning unit (16) which are mutually displaceably in program-controlled manner in order to alternatively convey powder from one of the powder receptacles of the powder stations or to clean the powder-flow itineraries using compressed cleaning air.

Abstract: The invention relates to a powder facility used for spray coating and comprising at least one injection unit (6), at least two powder stations (2) and at least one cleaning unit (16) which are mutually displaceable in program-controlled manner in order to alternatively convey powder from one of the powder receptacles of the powder stations or to clean the powder-flow itineraries using compressed cleaning air.

Abstract: A spray booth for use in the spray coating of articles with coating powder. The spray booth forms a coating space which at a bottom is bounded by powder collection means. The powder collection means is divided into an inner collection means and a surrounding outer collection means for the separate collection of surplus powder and the separate removal of the entire surplus powder from the booth. The outer collection means collects surplus coating powder dropping off the inside surfaces of the booth walls. Since this powder may be contaminated with different color or different types of powder from previous spraying operations, it is discarded as waste. The inner collection means collects pure surplus powder which has not touched the booth wall surfaces. This pure surplus powder is recycled.

Abstract: A time fuse for a non-spinning projectile has a pivoted catch connecting a fuse setting member to a setting disc whereby rotation of the member rotates the disc to wind a clockwork spring. A plunger is locked in a housing in the setting member by a movable ball or spring held by a spring-urged inertia block. When the fuse is set, the plunger acts on the catch to disconnect the disc and member upon displacement of the inertia block in response to axial acceleration of the projectile in a piece of ordnance.
