Title: Permanent magnet motor requiring no power supply - utilising repulsion energy of like magnetic poles involves magnets slanted at angle to radial direction
Inventor: HAAS EDUARD
IPC: H02K53/00
Filed: 1975-01-17
Abstract: A rotor (A) and a stator (B) are separated by a small airgap (C). Both carry an equally pitched number of permanent magnets which are placed at an angle to the radial and are separated from each other by impermeable layers (E). All magnets are arranged in the same pole direction so that at the gap only like poles appear, that is either all north or all south in the stator at least one magnet is omitted and replaced by an impermeable block (D). The angled magnets repell at an angle (2) to the tangential and thus produce a tangential component of torque (3) causing motion (4) of the rotor.

Title: Signal dependent distance meter - uses optical or other grating image superimposed on reference grating
Inventor: WITTE WOLFGANG DIPL PHYS DR
IPC: G01B11/14
Filed: 1975-03-19
Abstract: A distance meter is such that a signal depending on the distance of the object is used to generate a grating image which is projected on to a second similar grating, the image being shifted laterally between one position in which similar elements are superimposed and one in which dissimilar elements are superimposed. The two positions may be presented in alternating sequence. This permits an unambiguous measurement of the distance, independent of optical structures in the field of view. The grating elements may consist of any dissimilar elements, such as transparent/opaque, reflecting/absorbing, polarising in different planes etc. and the radiation passed by the superimposed and oscillating gratings, generates an alternating signal on meeting a suitable detector.
