Abstract: Rainwater collected from roof gutters is poured into the vertical portion of an “ell” shaped perforated drainage pipe. The horizontal leaching pipe portion of the drainage pipe discharges the rainwater into a catch basin. Water from the catch basin flows into another perforated leaching pipe that is set in the bottom of a trench. In turn, the lower part of the trench is filled with crushed rock to a height of about three quarters of the trench depth. A water impermeable barrier of asphalt shingles or thirty pound asphalt roofing felt is placed over the top of the crushed rock and the balance of the trench is filled with soil up to the ground level.

Abstract: A housing has open and closed ends, an interior and exterior surface between the ends, the exterior surface having front and rear faces with upper and lower faces. A drive screw within the housing has distal and proximal ends with a threaded surface. A drop leg has an exterior surface in sliding contact with the interior surface of the housing and an interior surface with threads operatively coupled with the threads of the drive screw.

Abstract: A pneumatic collet control system has a pneumatic cylinder subassembly with an internal shuttle subassembly with a central cylinder portion having an internal surface and a plurality of passageway holes on opposite ends of the cylinder communicating with the internal surface. The internal shuttle subassembly having a ram and a piston. A collet arm coupler is threadedly received into the external end of the ram. A valve body subassembly has a pair of valves and a pair of passageways for the valves for allowing and controlling the flow of actuating fluid into the cylinder with the passageways aligning with and coupling to the passageway holes of the cylinder. A central actuating fluid passageway connects with the two valves. A rotatable flow direction arm with a pivotable operator controlled handle controls the flow of actuating fluid into the cylinder.
