Abstract: An apparatus and method for an inspection apparatus for inspecting a component. The inspection apparatus including a robotic arm. A micro-XRF instrument having an instrument head coupled to the robotic arm. A seat supporting the component within a scanning area during inspection; and a computer in communication with the robotic arm and the micro-XRF instrument.

Abstract: A rearwardly tiltable chair set sturdily in a frame. The chair allows a user thereof to tilt back and thereby decompress the spine. The user may subsequently engage in exercises that flex, stretch, and strengthen the spine and its accompanying tendons, ligaments and muscles. The user is tilted back to a limited degree so that while the spine is allowed to decompress, blood does not rush to the head. The chair is pivotably held by the frame and tilts easily backward or forward so that the user can easily control his position. In an alternative embodiment, a resistive element is interposed between the back of the chair and the floor so that the user can exercise by pressing back upon the resistive element with the upper torso. A gauge may be coupled to the resistive element to measure the force applied by the user to the resistive element.

Abstract: Cylindrical water tanks, such as used for water softeners, inherently corrode at the bottom and herein is taught that the tanks are repaired by removing the bottom dish with the use of a novel tool that moves around the tank and bears there against with a substantially uniform force thereby readily following the tank's contour, by sandblasting the interior for cleaning, by installing a new bottom dish to the cylindrical body with the use of a novel tool that automatically stops further penetration of the dish into the tank when a predetermined overall height of the tank is obtained, by welding the bottom dish to the body, by coating the interior with a non-corrosive plastic with the use of a novel spray gun apparatus that radially sprays the liquid plastic onto the inner walls of the tank as the spray nozzle moves axially therein and then the spray nozzle is adjusted to cause the spray to form an upward diverging cone to coat the underside of the top cover, and finally by allowing the plastic to harden.
