Granted: 1993-08-25
Abstract: This inventive FBT places a magnet (14) in the  core  GAB  of the ferrite core (10). Polar direction of the magnet (N,S)  should be in the direction of  reducing theφ0  due  to  the  direction current (Idc), and this magnet also functions as the core gap.  As above mentioned, magnet field Hb  exists  in  fact,  however  zero magnet field effect is acquired in the view of ferrite  core  (10) usage. This effect is produced by placing the magnet having magnet field Hb in the ferrite core in  the  direction  of  reducing  the magnet flux  0 by the magnet field H0.

Abstract: PCT No. PCT/FR91/00776 Sec. 371 Date Sep. 17, 1993 Sec. 102(e) Date Sep. 17, 1993 PCT Filed Oct. 3, 1991 PCT Pub. No. WO92/06222 PCT Pub. Date Apr. 16, 1992.The invention relates to the field of metallurgy and to a method and a device for the extraction of zinc in solution in a liquid iron bath (2) held in a container (3), such as a crucible for the casting of foundry parts. It is characterized in that, before utilizing the bath for the casting of parts, in a first phase, the gas volume (7) situated in the container (3) is sealingly confined in the east iron bath (2) and, in a second phase, a variable partial vacuum is created in the confined atmosphere in a controlled way in order to constantly adjust it to a predetermined value as a function of the time evolution of the pressure of vapor saturating zinc in solution in the melt at the bath temperature; and said zinc is trapped.
