Title: Mfr. of pulse source with alternating magnetisable and non-magnetisable fields - involves deformation process subjecting source made of austenitic steel having face-centred cubic lattice
Inventor: RITTER JOACHIM DIPL ING
IPC: G01R33/02
Filed: 1991-07-26
Abstract: Method for manufacturing a pulse source with alternating magnetizable and non-magnetisable fields, esp. for use in sensors, consists of making this source initially of an austenitic steel with a face-centred cubic lattice. The alternating fields (which are to be magnetisable) of this source are then subjected to deformations which are sufficient to transform the face-centred cubic lattice into a tetragonally distorted body-centred cubic lattice. The fields which are to become magnetisable are subjected to an impact loading process. Before deformation the body undergoes a normalisation treatment. Such a body is basically a flat strip which after normalisation and impact loading is bent into a ring and its ends are joined. USE/ADVANTAGE - Used in transducer and instrument (speed indicators for example) mfr. In comparison with the known methods in this field, it constitutes a considerable simplification of the manufacturing technology
