Abstract: A method and apparatus to repair dents formed by a golf ball impacting the surface of a golf green. A restoring tool is mounted to the top of the handle of a putter, and this tool comprises a base member and a ground penetrating portion which is formed as a pair of tines and which is rotatably mounted to move from a stowed position flush against the base, to an operating position where it extends at right angles to the base. The putter is inverted so that the end of the handle can be positioned against the raised edge of the dent. The tines (outwardly extending) are moved to penetrate into the soil at a location outwardly of the raised edge of the dent, and the compression surface of the base member presses the sod layer downwardly and displaces the underlying ground layer laterally to fill into the recess portion of the dent. This also causes the displaced portion of the sod laterally over the dent.

Abstract: A parts washing method which utilizes a centrifugal filter to substantially reduce the need to replace its solvent. Solvent in a washing basin flows down a drain in the parts washing basin, through a screen to a centrifugal filter assembly, with a disposable filter in the filter receptacle of the centrifugal filter assembly. Thus the contaminated solvent flows from the drain, into a disposable filter element located in a spinning filter receptacle, where centrifugal force draws the solvent back into the solvent container while the materials washed from the part remain in the disposable filter element. The clean solvent is collected in a reservoir and recirculated back to the wash basin.

Abstract: A system for separating construction debris into low density debris and high density debris. The construction debris is delivered into a rotating drum having front and rear discharge openings. The lower portion of the drum is filled with water, and the debris is deposited onto the water, with the low density debris floating at the surface and the high density debris descending to the bottom of the drum. A plurality of high velocity water jets are positioned forwardly of the debris receiving location to create a turbulent high velocity water flow at an upper zone of the water in the drum to move the wood and other low density material toward a rear converging passageway that leads into the rear discharge opening. The higher density material is carried by a scroll type conveyor forwardly in the drum to a forward discharge location where rotating paddles lift the high density debris upwardly and thence move it into the front discharge opening.
