Abstract: a water softening system includes a water softening resin tank, an anion resin tank in flow communication with the water softening resin tank, an in-line water heater in flow communication with the water softening resin tank and a heat exchanger in flow communication with the in-line heater. A water heater is in flow communication with the heat exchanger and the in-line heater. A plurality of flow control valves are operatively connected to the water heater heat exchanger, in-line water heater, anion resin tank, and water softening resin tank. The flow control valves are configured to control the flow of water through the water softening system.

Abstract: An improvement in vehicle power take-off equipment is disclosed wherein a generator is affixed to the rear of the housing of a rotary air compressor of the type that is driven from a vehicle power take-off to an input shaft at its front end. The generator's housing is attached to the rear end of the air compressor's housing and the generator includes an armature mounted for rotation in the generator's housing. A rotary shaft extension projects from the rear of the air compressor. The armature receives the extension shaft and is coupled thereto by a friction fit and a threaded stud therebetween so that the armature turns with the extension shaft. The extension shaft is coupled for operation by the input shaft of the compressor so that both compressor and generator are directly operated by the input shaft of the compressor.
