A system to produce a high pressure stream of deionized water, for cleaning a body or bodies, comprising, in combination, a deionization bed within a first vessel, a first conduit or conduits to conduct non-deionized water at a relatively low pressure or pressures to pass through the bed to deionize
A system to produce a high pressure stream of deionized water, for cleaning a body or bodies, comprising, in combination, a deionization bed within a first vessel, a first conduit or conduits to conduct non-deionized water at a relatively low pressure or pressures to pass through the bed to deionize the water, a primary sensor to measure the deionization level of water that has passed through the bed, a second conduit or conduits to conduct water from the bed, a pump to receive water passed by the second conduit or conduits and to pressurize said received water to a level of at least about 1,200 PSI, a nozzle connected to the pump and operable to controllably dispense a high pressure stream of deionized water for highly effective cleaning of said bodies, and a hand truck carrying said vessel, conduits, pump and nozzle for transporting same to the location of said body or bodies.

A damper as set forth in claim 3, further including inner and outer skirt portions connected to the respective inner and outer damper members, the outer skirt portion guiding the movement of the inner skirt portion to maintain the respective inner and outer damper members in coaxial relationship when the damper members are moved relative to one another axially along the axis of the damper. 6. A damper as set forth in claim 2, wherein the funnel shape damper members are relatively movable rotationally about the axis of the damper. 7. A damper as set forth in claim 6, wherein the degree to which the inner and outer damper members are angularly displaced and the degree to which the apertures thereof are in registry is determinative of the amount of air flow through the damper. 8. A damper as set forth in claim 6, further including inner and outer skirt portions connected to the respective inner and outer damper members, the outer skirt portion guiding the movement of the inner skirt portion to maintain the respective inner and outer damper members in coaxial relationship when the damper members are moved relative to one another rotationally about the axis of the damper. 9. A damper as set forth in claim 2, further including inner and outer skirt portions connected to the respective inner and outer damper members, the outer skirt portion being sized to fit into a first duct. 10. A damper as set forth in claim 9, wherein the damper and first duct together form a damper assembly, the damper assembly being sized to fit into a second duct having a slightly larger cross section than that of the first duct. 11. A damper as set forth in claim 10, wherein the second duct comprises a flexible duct and the first duct is securely engaged therein by friction. 12. A damper as set forth in claim 1, wherein the apertures of the respective damper members are arranged in matching patterns. 13. A damper as set forth in claim 1, wherein the apertures of the respective damper members are substantially similar in shape. 14. A damper as set forth in claim 1, wherein the apertures are circular in shape. 15. A damper as set forth in claim 1, wherein when the damper members are in an open position, the respective apertures thereof align in a direction substantially perpendicular to the at least one wall of each member. 16. A damper as set forth in claim 1, wherein the damper members are frustopyramidal in shape. 17. A damper as set forth in claim 1, wherein the damper members are frustoconical in shape. 18. A damper as set forth in claim 17, wherein the axis with respect to which the respective at least one walls are inclined is coincident with the center axes of the frustoconical shape damper members. 19. A damper as set forth in claim 18, wherein the frustoconical shape damper members are relatively movable rotationally about the axis. 20. A damper as set forth in claim 18, wherein the frustoconical shape damper members are relatively movable axially along the axis. 21. A damper as set forth in claim 17, wherein the degree to which the at least one walls of the respective damper members are angularly displaced is determinative of the amount of air flow through the damper. 22. A damper as set forth in claim 21, further including an actuating assembly for relatively moving the damper members rotationally about the axis. 23. A damper as set forth in claim 21, wherein when the inclined walls are in the closed position, the apertures of the inclined wall of one of the damper members are fully blocked by the imperforate portions of the inclined wall of the other damper member. 24. A damper as set forth in claim 1, wherein the axis of the damper is defined by a direction of flow through the damper and the at least one walls of the respective damper members are relatively
