Abstract: A tissue rehabilitation treatment apparatus including a base power unit, hand unit, drive cable, and massage head unit. An extended drive shaft communicates rotational energy from the power unit to the drive cable, which in turn causes rotational and linear vibrating movement in the massage head unit. The cable is immersed in lubricant within a protective'sheath to provide strain relief along the drive cable. The apparatus includes a means for adjusting the vibrating frequency for treating a variety of ailments.

Abstract: A radial pump has a housing with a cylinder ring pivotally mounted therein. The cylinder ring has a circular aperture within which a cam surface is formed. A cylinder block rotates within the cylinder ring aperture and has a plurality of radially extending cylinders each having port which selectively communicates with a fluid inlet and a fluid outlet as the cylinder block rotates. A plurality of pistons is slideably received within the cylinders and engages the cam surface. The movement of the pistons within the cylinders is directly related to the magnitude of fluid flow delivered by the pump and moving the cylinder ring thereby controls the fluid flow.

Abstract: A multi-component system to feed two fluid materials, water and a cleaning agent, from a fluid tank to a spraygun is described. The fluid tank comprises a separation wall within the tank, to separate the two fluids from each other. A rechargeable battery-powered pump creates the pressure and the fluid components are drawn through their respective tube into a central tube, where the components combine before entering the spraygun.
