Abstract
Abstract A device for heating dielectric materials coating an electricity conducting element by means of hyperfrequency waves comprising a tubular conducting casing closed at both ends by conducting members, two aligned tubular conducting cores separated by a space coaxially disposed inside said tubular casing thus forming a coaxial guide, the dielectric material covering the conductive element being made to pass inside said two spaced tubular cores, a generator connected to said coaxial guide producing hyperfrequence waves applied on the dielectric element on the space between said tubular cores.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
176 words
Device for curing by means of hyperfrequency waves a dielectric material of an insulated wire or cable which is moved continuously, comprising, in combination: a tubular casing made of an electrically conductive material and at least partially closed at both of its ends by electrically conductive rings; at least two aligned tubes made of electrically conductive material which are disposed in a parallel fashion inside of said tubular casing and which are separated by a predetermined space; at least two insulating rings substantially parallel to said electrically conductive rings and being made of a material which is pervious to hyperfrequency waves, said insulating rings cooperating with said electrically conductive rings to support said tubes whereby said tubes form a coaxial guide with said tubular casing; and a generator of hyperfrequency waves operatively connected to said coaxial guide for producing an electric field therein, whereby said dielectric material of said insulated wire or cable when moving through said tubes and guided therein is subjected to said electric field only in said predetermined space which separates said tubes.
Claim 2
Dependent Claim
176 words
Device for curing by means of hyperfrequency waves a dielectric material of an insulated wire or cable which is moved continuously, comprising, in combination: a tubular casing made of an electrically conductive material and at least partially closed at both of its ends by electrically conductive rings; at least two aligned tubes made of electrically conductive material which are disposed in a parallel fashion inside of said tubular casing and which are separated by a predetermined space; at least two insulating rings substantially parallel to said electrically conductive rings and being made of a material which is pervious to hyperfrequency waves, said insulating rings cooperating with said electrically conductive rings to support said tubes whereby said tubes form a coaxial guide with said tubular casing; and a generator of hyperfrequency waves operatively connected to said coaxial guide for producing an electric field therein, whereby said dielectric material of said insulated wire or cable when moving through said tubes and guided therein is subjected to said electric field only in said predetermined space which separates said tubes.
Claim 3
Dependent Claim
47 words
Device according to claim 1, including a rectangular wave guide which is connected to said tubular casing; and an antenna operatively connected to said generator and being at least partially disposed within said rectangular wave guide to facilitate transmission of said electric field to said coaxial guide.
Claim 4
Dependent Claim
37 words
Device according to claim 1, wherein the internal surfaces of said aligned tubes are covered with a material which is pervious to said hyperfrequency waves and which has a substantially low coefficient of friction, such as polytetrafluorethylene.
Claim 5
Dependent Claim
33 words
Device according to claim 1, including two sections of coaxial conductors connected to said tubular casing and one of said aligned tubes to facilitate transmission of said electric field to said coaxial guide.
Claim 6
Dependent Claim
38 words
Device according to claim 2, wherein said rectangular wave guide is provided at its ends with short circuit buttons for effecting an electronic matching or adaptation of the device to the impedence of said generator of hyperfrequency waves.
Claim 7
Dependent Claim
55 words
Device according to claim 1 in which means are provide to move said insulating rings of material pervious to hyperfrequency waves for effecting the adaptation of the impedence of the load, formed by the portion of said dielectric material which is subjected to said electric field, to the impedence of said generator of hyperfrequency waves.
Claim 8
Dependent Claim
17 words
Device according to claim 6 in which said insulating rings are made at least partially of polytetrafluorethylene.
