Title: Electronic axle measuring device - measures wheel plane deviation from vertical and car longitudinal axis
Inventor: HESS BRUNO
IPC: G01B7/315
Filed: 1973-11-23
Abstract: Measurements are made of distances between a reference plane and a disc mounted on the wheel. The disc is mounted on the wheel without adjustments. Two pairs of feelers are placed crosswise in front of the disc. A store is allocated to each feeler, in which the smallest distance between the disc and feeler during one wheel revolution is stored. Differences between these minima in the vertical and horizontal planes are formed, and directly displayed for camber and alinement. After first wheel revolution and when it is stationary again, instantaneous values of all feelers are determined, compared with previously obtained values, and the differences stored as correction values. After dynamic measurement the wheel is stopped in a position in which the disc inclination is minimum.

Title: Round workpiece axis or centre measuring device - measures and compensates the workpiece axis or centre eccentricity
Inventor: HEIDER HANS-JUERGEN
IPC: G01B7/312
Filed: 1974-03-18
Abstract: The workpiece surface is interrupted in one or several large sections. A trigger responds at a beginning of the periphery discontinuity. It disconnects the integrator inputs and simulates a signal corresponding to an ideal circle.
