Title: Guide system for non-contact guidance of parts moving against each other
Inventor: LOEFFLER HORST DIPL ING
IPC: F16F6/00
Filed: 1994-04-30
Abstract: The air gap widths are held at a constant value against the reaction of the external forces, by current alterations in the excitation coils (2). The inductance of the electromagnets varying with the air gap width, is used for the measurement of the air gap width. A test signal is superimposed on the coil current, required for holding the air gap width constant e.g. an AC voltage of constant amplitude and frequency, which at a measurement resistance lying in series with the excitation coil, produces a signal component proportional to the inductance of the excitation coil.

Patent DE-4424136-A1 (DE)
Title: Testing uniformity of motor vehicle tyres
Inventor: MOTZKUS ANDREAS
IPC: G01M17/02
Filed: 1994-07-08
Abstract: The tyre uniformity testing involves a rotationally mounted tyre which is pressed on and rotated by a pressure roller (2). A force measurement unit (20) measures the axial reaction force on the tyre due to irregularities, and a geometry measuring unit (10) scans the geometric contour of the tyre (1), for producing a geometric measurement signal (14), characterising the geometric dimensions of the tyre (2). The defect in the force signal, which results from the influence of the tyre deformation with the rolling on of the pressure wheel (2), is compensated, with the help of the determined force measuring signal (24). The force measurement signal is divided by a spring strength of the tyre and is subtracted from the geometric measuring signal. Whilst taking account of an angular displacement ( alpha ) of the geometry measuring unit compared to the pressure wheel.
