Abstract: Dans un moteur a courant continu sans collecteur pourvu d'un rotor (11) a aimants permanents, on utilise une magnetisation des poles rotoriques (N, S) qui differe fortement de la forme sinusoidale. En plus de l'enroulement principal (35-47) qui sert a l'entrainement du moteur, le stator est en outre muni d'un enroulement de detection (80) agence de maniere a capter une harmonique de la tension induite dans le stator par les poles rotoriques (11), par exemple la deuxieme harmonique.

Title: Method and apparatus for testing metal tapes.
Inventor: WEISCHEDEL HERBERT R
IPC: G01N27/72
Filed: 1980-09-10
Abstract: Magnetic flux is induced in the tape (10) by applying a magnetic field to the tape. Where there is a perforation (12) or a crack (14) air gaps are created and magnetic flux (15, 18) radiates outwardly from the tape across these air gaps. The presence of the crack (14) is detected by sensing the radiating flux (15, 18) at two distances from the tape. At one distance (30), close to the tape, the total flux is the sum of the flux from the crack and the perforation. At the other distance (32), further from the tape, the flux is solely that produced by the perforation. A coil (36, 38) is placed at each position to sense the flux. The tape (10) is moved, which causes the flux (15, 18) to intersect the coils (36, 38). The intersection produces an output signal (40) from each coil (36, 38). The signal (40) produced by the coil (38) further from the tape is subtracted from the signal (40) produced by the coil (36) closer to the tape; the difference being a signal (58) caused by the additional flux produced by the crack (14). An alarm (94) is sounded and an indicator (88) lights when the signal is present.

Abstract: Apparatus for heating liquid foodstuffs has at least three electrodes 14 spaced along a pipe 10, 12, 13 to make contact with material flowing in the pipe. Power supply 15, 16 causes current to flow in the material between electrodes. The pipe lengths 12 and 13 between adjacent pairs of electrodes 14 are different lengths selected to make the electrical resistance in the material between the adjacent pairs of electrodes substantially equal. Since the resistivity normally falls for increasing temperature, the downstream pipelength 13 is longer.
