Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
93 words
In a superconductive switch for use at the terminals of a superconductive storage winding; said switch comprising: a main superconductive winding wound round an axis of symmetry and, in the vicinity of the said main winding, magnetic control windings wound around the same axis for making the said main winding change over to a normal state, the improvement wherein: at least one of the said main and control windings consists of turns having a variable radius and whose number of turns centered on the said axis, increases from one end to the other.
Claim 2
Dependent Claim
93 words
In a superconductive switch for use at the terminals of a superconductive storage winding; said switch comprising: a main superconductive winding wound round an axis of symmetry and, in the vicinity of the said main winding, magnetic control windings wound around the same axis for making the said main winding change over to a normal state, the improvement wherein: at least one of the said main and control windings consists of turns having a variable radius and whose number of turns centered on the said axis, increases from one end to the other.
Claim 3
Dependent Claim
81 words
The switch according to claim 1, wherein: a section passing through the said axis of symmetry has the cross-sections of the turns of thE said main winding contained in a rectangle having a small side perpendicular to said axis of symmetry which is arranged on the outside of the said rectangle, and the cross-sections of the turns of said control windings contained in two right-angled triangles whose right-angle has one of its sides parallel to the large side of said rectangle.
Claim 4
Dependent Claim
81 words
The switch according to claim 1, wherein: a section passing through the said axis of symmetry has the cross-sections of the turns of said main winding contained in an isosceles trapezium whose bases are perpendicular to said axis of symmetry, which is arranged on the outside of the said trapezium, and the cross-sections of the turns of said control windings contained in two parallelograms one of whose large sides is parallel to one of the non parallel sides of said trapezium.
Claim 5
Dependent Claim
81 words
The switch according to claim 1, wherein: a section passing through the said axis of symmetry has the cross-sections of the turns of the said main winding contained in an isoceles trapezium having a base perpendicular to said axis of symmetry, which is arranged outside the said trapezium and the cross-sections of the turns of said control windings contained in two triangles whose obtuse angle has one of its sides parallel to one of the non parallel sides of said trapezium.
