THE METHOD OF THAWING FROZEN LIQUID WHICH COMPRISES PLACING THE FROZEN LIQUID IN AN ENCLOSURE AND SUBJECTING IT TO A HIGH FREQUENCY ELECTRONMAGNETIC FIELD TO PRODUCE DIELECTRIC HEATING AND PROGRESSIVE MELTING OF THE FROZEN LIQUID, AND CONTINUALLY WITHDRAWING THE LIQUID FROM THE ENCLOSURE SUBJECTED TO THE HIGH FREQUENCY FIELD AS IT IS PRODUCED BY MELTING.
Claim 2
Independent Claim
55 words
THE METHOD OF THAWING FROZEN LIQUID WHICH COMPRISES PLACING THE FROZEN LIQUID IN AN ENCLOSURE AND SUBJECTING IT TO A HIGH FREQUENCY ELECTRONMAGNETIC FIELD TO PRODUCE DIELECTRIC HEATING AND PROGRESSIVE MELTING OF THE FROZEN LIQUID, AND CONTINUALLY WITHDRAWING THE LIQUID FROM THE ENCLOSURE SUBJECTED TO THE HIGH FREQUENCY FIELD AS IT IS PRODUCED BY MELTING.
Claim 3
Dependent Claim
72 words
APPARATUS FOR MELTING A FROZEN LIQUID COMPRISING AN ENCLOSURE PROVIDING ELECTROMAGNETIC SHIELDING, MEANS COUPLING ELECTROMAGNETIC ENERGY TO THE INTERIOR OF SAID ENCLOSURE, AND MEANS DEFINING AT LEAST ONE DRAINAGE PASSAGE IN THE FLOOR OF SAID ENCLOSURE HAVING A DIMENSION WHICH IS SMALL COMPARED TO THE WAVELENGTH OF THE HIGH FREQUENCY ELECTROMAGNETIC ENERGY TO DRAN LIQUID FROM SAID ENCLOSURE AS IT IS FORMED BY THE MELTING OF THE FROZEN LIQUID WITHIN SAID ENCLOSURE.
Claim 4
Dependent Claim
72 words
