Abstract: A well service pump system supplies high pressure working fluid to a well. The pump system includes a closed-loop hydraulic circuit for actuating a plurality of working pump assemblies. The pump system is powered by a motor, which transfers mechanical energy to a plurality of pumps, which, in turn, provide hydraulic fluid to operate hydraulic ram cylinders, and thereby operate the working pump assemblies. Each of the polished rods of the hydraulic ram cylinders is connected axially to a plunger rod end of the working fluid end cylinder to operate the working pump assembly.

Abstract: A plastic pallet and method of construction that permits plastic pallets of numerous different sizes and options to be easily produced from only a very small inventory of parts and without requiring a user to purchase or construct numerous different shapes and sizes of molds in order to produce a wide variety of pallets of various shapes, sizes and options.

Abstract: A fire resistant roofing tile which utilizes economical materials and is formed using an efficient manufacturing technique. The tile has components shaped to prevent fire spread significantly enough to achieve a Class A fire retardation rating. Recycled materials are used in a compression molding process for commercial appeal and benefit to the ecology.

Abstract: A compression molded pallet system which may be used as a single layer pallet or converted into a double layer rackable pallet when desired. The pallet is comprised of highly flame resistant materials which are formed from recycled rubber and plastic materials for benefit to the ecology. A novel reinforcing rib pattern is disclosed. Anti-skid elements are also disclosed as a part of the overall system.

Abstract: A curved roofing tile which is formed of strong materials so that it may be fabricated in an extra-width configuration. Strengthening ridges and connector ridges are compression molded so the roofing tile forms a one-piece unit. To help the ecology, recycled materials such as rubbers and plastics are combined into a novel formula of high strength, Class A flame retardancy and economy of manufacture.

Abstract: A pallet which is specially designed for use in combination with a particular manufacturing process. The pallet includes air ventilation apertures which allow an upper product-containing bag to breathe. Specially designed upper channels allow further ventilation and bag pick-up or deposit when desired during a manufacturing process. The underside of the pallet includes reinforced areas and multiple entry ports for use with a fork-lift truck.
