Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
103 words
An inductor for shaping parts by pulsed magnetic field pressure comprising: a concentrator having an axial opening extending throughout its length, a portion of said opening serving to receive a part to be shaped therein; a winding for inducing current in said concentrator and disposed on a portion of the outer side surface of said concentrator around said part of the axial opening with said part to be shaped placed therein, the other portion of said outer side surface of said concentrator extending in a radial direction, in the form of fins to ensure cooling of the concentrator through contact with cooling means.
Claim 2
Dependent Claim
103 words
An inductor for shaping parts by pulsed magnetic field pressure comprising: a concentrator having an axial opening extending throughout its length, a portion of said opening serving to receive a part to be shaped therein; a winding for inducing current in said concentrator and disposed on a portion of the outer side surface of said concentrator around said part of the axial opening with said part to be shaped placed therein, the other portion of said outer side surface of said concentrator extending in a radial direction, in the form of fins to ensure cooling of the concentrator through contact with cooling means.
Claim 3
Dependent Claim
40 words
An inductor for shaping parts by pulsed magnetic field pressure as claimed in claim 1, wherein said portion of the outer side surface of the concentrator extending in the radial direction is held in a vessel filled with cooling means.
