Abstract: An endless belt filtering system for separating solid particles from a flow of contaminated liquid to produce a generally clean liquid. The system having a continuous loop belt extending between a first end and a second end and being formed by a plurality of plates pivotably joined to one another about space horizontal axes. The plurality of plates together forming an outwardly facing side and an inwardly facing side, the belt further including an upper section wherein the outward side generally faces up and moves from the first end toward the second end and an opposite lower section wherein the outward side generally faces down and moves from the second end toward the first end. The system having a housing forming a tank with a bottom, an end wall near the first end and a pair of side walls extending from the end wall.

Abstract: The difficulties and drawbacks of previous-type systems are overcome by the present invention which includes a locking device for a firing spring housing in a firearm. A main housing is provided including an internal cylindrical portion for receiving a firing spring. A lock rod is received in the main housing, for selectively engaging the firing spring. The lock rod is movable between an engagement position and a disengagement position with the firing spring. A combination disk is provided for engaging the lock rod, to selectively fix the lock rod in one of the engagement position and the disengagement position.
