A mobile chiropractic vehicle comprising a rectangular enclosure have two opposed end walls, two opposed lateral walls, a ceiling and a floor defining an interior area; at least one axle having a pair of wheels, each on opposite ends of the axle, the at least one axle being secured transversely to the rectangular enclosure adjacent the floor to enable movement of the rectangular enclosure; a first arrangement associated with one of the two opposed end walls to transport the rectangular enclosure to selected locations; a second arrangement associated with the other of the two opposed end walls to provide handicapped access to the rectangular enclosure; and a retractable arrangement disposed between the two opposed lateral walls in a spaced relationship with the two opposed end walls to divide the interior area into a patient waiting area adjacent the second arrangement and an examining, diagnostic and adjusting area adjacent the one of the two opposed end walls when the retractable arrangement is closed and a viewing area for a multimedia chiropractic presentation projected on a screen adjacent the one of the two opposed end walls when the retractable arrangement is open.

Power chuck for movable elements or opening and closing its jaws, characterized in that at least one such element is enclosed in or forms a boundary of an essentially sealed cavity which is at least temporarily connected through at least one supply channel with a source of lubricating fluid and at least temporarily connected through at least one discharge channel with a sink for the lubricating fluid. 8. Power chuck according to claim 7 characterized in that a slit of a bed track of at least one jaw of the chuck communicates with the cavity. 9. Power chuck according to claim 7, characterized in that the source and the sink for the lubricating fluid are stationary. 10. Power chuck according to claim 9, characterized in that a slit of a bed track of at least one jaw of the chuck communicates with the cavity. 11. Power chuck according to claim 7, where the jaws of the chuck are actuated by a hydraulic circuit he actuating circuit of which comprises an activating conduit which delivers the pressure for closing the jaws and a releasing conduit which delivers the pressure for opening the jaws, characterized in that either the activating conduit serves as the supply channel and the releasing conduit serves as the discharge channel, or vice-versa. 12. Power chuck according to claim 11, characterized in that the cavity is connected to the actuating conduit and/or to the releasing conduit through at least one passage in which fluid can flow towards the respective conduit when the pressure in the cavity exceeds that in said conduit. 13. Power chuck according to claim 12, characterized in that the actuating circuit comprises a cylinder and piston unit operating the jaws of the chuck, and that there is a return valve between said unit and the activating conduit, said return valve blocking the flow away from the unit unless it is released through the action of the pressure in the release conduit. 14. Power chuck according to claim 13, characterized in that a passage connects the cavity to a place in the activating circuit which lies on the side of the return valve facing away from the cylinder and piston unit, and that said passage contains a one-way valve which only allows a flow of fluid way from the cavity. 15. Power chuck according to claim 7, characterized in that the supply channel and/or the discharge channel contain a choking nozzle. 16. Power chuck according to claim 13, characterized in that the supply channel and/or the discharge channel contain a choking nozzle.
