Appeal 2007-0881
Application 10/250,972
We reverse the decision of the Primary Examiner.
Claim 11 illustrates Appellant’s invention of a device which is useful
for braking a flow of molten metal in a device for continuous or semi-
continuous casting of metals in a generally vertically arranged mold with
opposite broad sides and short sides, and is representative of the claims on
appeal.
11. A device for braking a flow of molten metal in a device for
continuous or semi-continuous casting of metals in a mold which is provided
with opposite broad sides and opposite short sides, the device comprising:
two magnet cores facing a respective one of the short sides of the
mold for generating a magnetic field and an induced current in a region of
the molten metal adjacent to each respective short side, the cores being
arranged such that the magnetic field generally has a direction perpendicular
from the respective short side of the mold towards the center of the latter,
wherein the mold is generally vertically arranged and at least one of the
cores is arranged in or below a region wherein a flow of molten metal
impinges the inner surface of an short side of the mold in a direction
obliquely downwards; and
a winding comprising an electric conductor wound around each
magnet core.
