Abstract: A system to provide an efficient, faster, and consistent slurry material application through utilizing a digital positioning receiver and micro controller as means for adjusting output flow rates and percentages of the individual materials within the slurry recipe. This slurry control system consists of a digital positioning receiver for means of sensing vehicle speed, a hydraulically motor controlling the aggregate and emulsion, an electronic liquid additive flow meter, an electronically controlled water flow meter, a dry additive hydraulic motor, an adjustable display, a dedicated prime mover and pump, and a programmed micro controller to proportionally control each material of the slurry recipe to accomplish each of their target output flow rates and percentages.

Abstract: The present invention is directed to a swimming pool cover assembly useful to facilitate the installation of a cover having the tendency to sink when placed on the surface of the pool. The cover assembly comprises a plastic sheet and a flotation device. The sheet has a size and configuration generally adapted to cover the water surface of the pool, a top side, and a bottom side provided with one or more fasteners. The flotation device has one or more complimentary fasteners to permit assembly to and disassembly from the bottom side of the sheet. The floatation device also has sufficient buoyancy to maintain the sheet at or near the water surface when the sheet and attached floatation device are placed on the water during installation of the cover over the pool.
