Abstract: A technique which facilitates cleaning of an interior of a pipe via access through a lateral hole in the pipe. The technique utilizes a control bar head coupled with a sweeper system which may be inserted into the pipe through the lateral hole. The sweeper system may comprise a plurality of shiftable sweeper heads which generally align for insertion through the lateral hole and then transition along the interior of the pipe to effectively sweep particles along the interior of the pipe. The sweeper system effectively clears an area of the interior of the pipe to facilitate a more effective seal with a subsequently inserted pipe isolation device.

Abstract: A spray booth especially adapted for painting operations having a dry filter module with features for allowing changing of the filters quickly and in a contained environment, which reduces exposure to non-authorized and non-properly-protected personnel. A carousel-like filter module flips a wall to move dirty filters into a containment space while placing clean filters in position to continue the painting process. The process and device in accordance with this invention is safe, repeatable, predictable, and capable of changing a large number of filters in a short period of time, for example, during lunch break or other short break in the painting operation.
