Abstract
Abstract This invention related to effecting the movement of liquids by electromagnetic means. Liquids, as used herein, should be understood to include fluids, generally such as gases, vapors, and plasma. By the proper adjustments of temperature and pressure, materials may be handled as liquids, vapors, or plasma. Fluidized solids are also contemplated within the scope of the term liquid, as are magnetic fluids.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
99 words
Apparatus for casting metals comprising selectively shaped mold means adapted to receive a charge of electromagnetically displaceable liquid metal having a temperature above its solidification temperature means for subjecting the received charge of liquid metal to a selectively directed displacement inducing rotating magnetic field to effect displacement thereof within said mold means, means for subjecting the container charge of liquid metal to a selectively directed Lorentz force for supplementing the displacement of the charge within said mold means induced by said rotating magnetic field, whereby solidification thereof, while in contact with the contour defining mold surfaces, can be effected.
Claim 2
Dependent Claim
99 words
Apparatus for casting metals comprising selectively shaped mold means adapted to receive a charge of electromagnetically displaceable liquid metal having a temperature above its solidification temperature means for subjecting the received charge of liquid metal to a selectively directed displacement inducing rotating magnetic field to effect displacement thereof within said mold means, means for subjecting the container charge of liquid metal to a selectively directed Lorentz force for supplementing the displacement of the charge within said mold means induced by said rotating magnetic field, whereby solidification thereof, while in contact with the contour defining mold surfaces, can be effected.
Claim 3
Dependent Claim
24 words
Apparatus as set forth in claim 1 including means for effectinG electromagnetically-induced agitation of said charge prior to its introduction into said mold means.
Claim 4
Dependent Claim
24 words
Apparatus as set forth in claim 3 including means for effectively electromagnetically-inducing displacement of said charge from a source thereof into said mold means.
Claim 5
Dependent Claim
25 words
Apparatus as set forth in claim 1 wherein said means for creating said displacement inducing rotation magnetic field induces heat generation within the displaced charge.
Claim 6
Dependent Claim
33 words
Apparatus as set forth in claim 1 wherein said selectively shaped mold means is a moving liquid of greater density than said charge and whose displacement is induced by externally applied electromagnetic forces.
Claim 7
Independent Claim
64 words
A method of casting metals in a selectively shaped mold comprising introducing a charge of electromagnetically-displaceable liquid metal at a temperature above its solidification temperature into the mold, displacing the received charge in a selected direction by establishing a rotating magnetic field, and supplementing the displacement of the received charge by generating a selectively directed Lorentz force, whereby the solidification thereof can be effected.
Claim 8
Independent Claim
64 words
A method of casting metals in a selectively shaped mold comprising introducing a charge of electromagnetically-displaceable liquid metal at a temperature above its solidification temperature into the mold, displacing the received charge in a selected direction by establishing a rotating magnetic field, and supplementing the displacement of the received charge by generating a selectively directed Lorentz force, whereby the solidification thereof can be effected.
Claim 9
Dependent Claim
35 words
The method as set forth in claim 6 including the steps of introducing the charge of castable material into operative engagement with said contour defining mold surface by electromagnetically-induced displacement from a molten supply thereof.
Claim 10
Independent Claim
77 words
An apparatus for displacing electromagnetically displaceable bodily fluids comprising means for subjecting a bodily fluid flowing along a bodily conduit to a selectively oriented rotating electromagnetic field for inducing the displacemt thereof along the conduit, means for conjointly subjecting the bodily fluid to a selectively directed Lorentz force for supplementing the displacement thereof along the bodily conduit, and a source of electrical energy located exteriorly of the body for establishing said electomagnetic field and said Lorentz force.
Claim 11
Independent Claim
77 words
An apparatus for displacing electromagnetically displaceable bodily fluids comprising means for subjecting a bodily fluid flowing along a bodily conduit to a selectively oriented rotating electromagnetic field for inducing the displacemt thereof along the conduit, means for conjointly subjecting the bodily fluid to a selectively directed Lorentz force for supplementing the displacement thereof along the bodily conduit, and a source of electrical energy located exteriorly of the body for establishing said electomagnetic field and said Lorentz force.
