A unitary adaptor plate for determining static unbalance in a body. The plate includes an outer body, a middle body, and an inner body, and each of the inner and outer bodies is connected to the middle body by means of opposed torsion elements to provide a structure that defines a gimbal system capable of rotation about two mutually perpendicular axes of rotation defining two degrees of freedom of the adaptor plate. Deflection sensors sense the inclination of the adaptor plate caused by unbalance in a body placed on the adaptor plate, and force transducers operate to restore the plate to a horizontal position and provide an output indicative of the unbalance of the body.

Apparatus for determination of the static unbalance in a body

A method and an apparatus for determination of run-out of a rotating body, especially an automobile tire, without the need for mechanically contacting the rotating body. The apparatus includes a device for rotating the body, a scanning system with a transmitter for transmitting parallel rays directed toward the rotating body, a receiver to receive the residual rays not blocked by the rotating body, and an analyzer circuit for determination of variations in blockage on the basis of which run-out of the rotating body is determined.

Method and apparatus for non-contact determination of run-out of a

Apparatus for automatically inspecting and moving tires through an inspection system. The tire is placed in a pan of sand and is rotated by a device grasping the bead of the tire so that the tire becomes embedded in the sand in order to stabilize its position. A covering hood, with an attached mirror, is aligned upon lowering with the aid of conical centering guides. After the tire has been inspected and removed, a rotary shovel smooths the sand so that the pan is ready to accept another tire for inspection.
