Abstract
Abstract An inductor for shaping parts by pulsed magnetic field pressure comprising a concentrator having an axial opening for placing a part to be shaped therein, a winding disposed at the outer surface of said concentrator wherein a radial slot is made along a portion of the length of the concentrator forming laterial surface, the slot having at its end an electric circuit whose inductance is considerably higher than that of the circuit of the axial opening with a part being shaped therein.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
114 words
An inductor for shaping parts by pulsed magnetic field pressure comprising: a concentrator having an outer surface and being provided with an axial opening for placing a part to be shaped therein; a winding disposed at the outer surface of said concentrator; said concentrator having a radial slot extending axially along only a portion of the length of said concentrator, said slot having an end with an electric circuit at said end of the slot, said electric circuit having an inductance considerably higher than that of the circuit of said axial opening said electric circuit extending axially from said slot over only a portion of the concentrator remaining beyond said end of the slot.
Claim 2
Dependent Claim
114 words
An inductor for shaping parts by pulsed magnetic field pressure comprising: a concentrator having an outer surface and being provided with an axial opening for placing a part to be shaped therein; a winding disposed at the outer surface of said concentrator; said concentrator having a radial slot extending axially along only a portion of the length of said concentrator, said slot having an end with an electric circuit at said end of the slot, said electric circuit having an inductance considerably higher than that of the circuit of said axial opening said electric circuit extending axially from said slot over only a portion of the concentrator remaining beyond said end of the slot.
Claim 3
Dependent Claim
35 words
An inductor as claimed in claim 1 wherein said electric circuit is constituted by a radial opening in said concentrator at said end of the slot, said radial opening being substantially wider than said slot.
Claim 4
Dependent Claim
33 words
An inductor as claimed in claim 2 wherein said concentrator includes a solid portion extending beyond said radial opening in a direction away from said slot, and means for cooling said solid portion.
Claim 5
Dependent Claim
34 words
An inductor as claimed in claim 2 wherein said axial opening has a smaller diameter portion for receiving the part to be shaped, and a larger diameter portion in the remainder of the concentrator.
