Title: Two wire electrical measurement transducer - has main analogue path and digital correction path, enabling continuous measurement and rapid parameter change tracking
Inventor: POPP WERNER
IPC: G01D5/14
Filed: 1990-05-25
Abstract: An electrical measurement transducer contains a sensor for the measurement parameter.

Title: Shunt wound permanent magnet motor - generates mechanical energy from field energy of permanent magnet within motor from difference in field strength in two motor halves
Inventor: PFAUTSCH EMIL
IPC: H02K53/00
Filed: 1990-11-22
Abstract: The motor has halves (1A, 1B) of identical construction. Both halves contain a horseshoe magnet (1) and a rod magnet (4) rotatably located at the poles.
