Method of treating fibrous material utilizing a radio-frequency field which extends predominantly at right angles to the length of said material

Claim 1

THE METHOD OF TREATING FIBROUS MATERIAL WHICH INCLUDES APPLYING THERETO A SUFFICIENT QUANTITY OF BONDING SOLUTION TO MECHANICALLY IMPREGNATE THE FIBERS THROUGHOUT; AND IMMEDIATELY APPLYING TO THE FIBROUS MATERIAL OVER A SUBSTANTIAL AREA THEREOF A RADIO-FREQUENCY FIELD WHICH EXTENDS PREDOMINANTLY AT RIGHT ANGLES TO THE LARGEST SURFACE OF SAID MATERIAL TO THEREBY CREATE SUCH A UNIFORM FIELD WHICH WILL CAUSE THE SOLUTION BINDER SOLIDS TO BECOME FLUID TO THE EXTENT OF PRACTICALLY NULLIFYING THE VISCOSITY OF SAID BINDER SOLIDS UNIFORMLY THROUGHOUT WHEREUPON SAID FIELD WILL FORCE THEM INTO THE INTERSTICES BETWEEN THE FIBERS TO THE EXTENT OF PRODUCING SUBSTANTIALLY COMPLETE INTERPENETRATION AND ADSORPTION OF ALL AVAILABLE FIBER SURFACES UNIFORMLY, THUS COMPLETING AND PERFECTING ANY AFOREMENTIONED MECHANICAL IMPREGNATION BEFORE THE SETTING OF THE BINDER OF THE SOLUTION, AND THEN, BY THE CUMULATIVE UNIFORM HEATING ACTION OF SAID FIELD UPON LY SET THE BINDER IN PLACE IN THE FIBROUS MASS; WHEREBY WHEN DRY, THE TENSILE STRENGTH OF THE FIBROUS MASS IS INCREASED OVER THAT WHICH WOULD BE OBTAINED BY ANY MECHANICAL IMPREGNATION AND SUBSEQUENT DRYING WITHOUT THE USE OF THE AFOREMENTIONED SPECIFICALLY APPLIED RADIOFREQUENCY FIELD.

Claim 2

THE METHOD OF TREATING FIBROUS MATERIAL WHICH INCLUDES APPLYING THERETO A SUFFICIENT QUANTITY OF BONDING SOLUTION TO MECHANICALLY IMPREGNATE THE FIBERS THROUGHOUT; AND IMMEDIATELY APPLYING TO THE FIBROUS MATERIAL OVER A SUBSTANTIAL AREA THEREOF A RADIO-FREQUENCY FIELD WHICH EXTENDS PREDOMINANTLY AT RIGHT ANGLES TO THE LARGEST SURFACE OF SAID MATERIAL TO THEREBY CREATE SUCH A UNIFORM FIELD WHICH WILL CAUSE THE SOLUTION BINDER SOLIDS TO BECOME FLUID TO THE EXTENT OF PRACTICALLY NULLIFYING THE VISCOSITY OF SAID BINDER SOLIDS UNIFORMLY THROUGHOUT WHEREUPON SAID FIELD WILL FORCE THEM INTO THE INTERSTICES BETWEEN THE FIBERS TO THE EXTENT OF PRODUCING SUBSTANTIALLY COMPLETE INTERPENETRATION AND ADSORPTION OF ALL AVAILABLE FIBER SURFACES UNIFORMLY, THUS COMPLETING AND PERFECTING ANY AFOREMENTIONED MECHANICAL IMPREGNATION BEFORE THE SETTING OF THE BINDER OF THE SOLUTION, AND THEN, BY THE CUMULATIVE UNIFORM HEATING ACTION OF SAID FIELD UPON LY SET THE BINDER IN PLACE IN THE FIBROUS MASS; WHEREBY WHEN DRY, THE TENSILE STRENGTH OF THE FIBROUS MASS IS INCREASED OVER THAT WHICH WOULD BE OBTAINED BY ANY MECHANICAL IMPREGNATION AND SUBSEQUENT DRYING WITHOUT THE USE OF THE AFOREMENTIONED SPECIFICALLY APPLIED RADIOFREQUENCY FIELD.
