Abstract

An electrical conducting apparatus comprising an envelope, or in an alternative embodiment, a brother-pair of envelopes, in which said envelope encompasses a magnetic field whereby fluctuations in the magnetic field may be sensed or tapped-off by two half-turn type conducting circuits. The conducting envelope provides a cross-sectional area for encompassing the magnetic field and has a longitudinal severance line or slit which divides the envelope into two sections symmetrical to each other. At a location of 180° from the severance line is a center-tap terminal, while two output terminals are provided on each side of the severance line thus to provide two half-turn winding circuits in relationship to the center-tap terminal. Useful configurations of said envelope may include a rectangular shape, a tubular shape, a spiral shape, which may be arranged into symmetrical pairs of envelopes which are oriented at a 180° relationship to each other to form a brother-pair of two sets of two half-turn windings having a center tap.

Claims

1. An electrical conductor apparatus for encompassing a magnetic field comprising:

(a) a first pair of spiral shaped electrical strip conductors which are aligned along the longitudinal axis of said magnetic field, and wherein a first one of said conductors spirals clockwise and the other conductor spirals counterclockwise around said axis of said magnetic field,

(b) a second pair of spiral shaped conductors longitudinally aligned along said axis of said magnetic field and wherein a first one of said conductors spirals clockwise and a second one of said conductors spirals counterclockwise around said axis of said magnetic field,

(c) and wherein each of said pair of spiral conductors is insulated from the other and electrically connected such that each spiral pair of conductors forms a balanced pair of half-turn windings via output terminals at one end relative to a center tap at the opposite end which electrically connects said pair of spiral conductors.

2. An electrical conductor apparatus for encompassing a magnetic field running therethrough and forming two half-turn circuits relative to a center-tap terminal, said conductor apparatus comprising:

(a) a first electrically conducting envelope encompassing said magnetic field, said envelope having a longitudinal slit dividing said envelope symmetrically into two sections, said envelope including;

(a1) an electrically conductive center-tap terminal located at a point 180°

from said longitudinal slit and residing equidistant from said slit measured along either one of said two sections;

(a2) a first and a second electrical output terminal located respectively on each side of said longitudinal slit at the same end thereof;

(b) a second electrically conducting envelope which symmetrically duplicates said first envelope and has a longitudinal slit dividing said envelope symmetrically into two sections, said second envelope including;

(b1) an electrically conductive center-tap terminal located at a point 180°

from said longitudinal slit and residing equidistant from said slit measured along either one of said two sections;

(b2) a first and second electrical output terminal located respectively on each side of said longitudinal slit at the same end thereof;

(c) wherein said second envelope encompasses said first envelope concentrically and the envelopes are insulated from each other while being oriented such that the longitudinal slit of said first envelope is located 180°

from the said longitudinal slit of said second envelope.

3. The conductor apparatus of claim 2 wherein said first and second envelopes form a brother-pair of envelopes which encompass approximately the same cross section area of magnetic field passing therethrough.

4. The conductor apparatus of claim 3 wherein said brother-pair of envelopes include a common electrical connection between the center-tap terminals of said first and second envelopes.

5. The conductor apparatus of claim 3 wherein each of said envelopes is formed of a hollow tube of rectangular cross-section and said second envelope is of a slightly larger cross-section than said first envelope to provide insulative separation from said first envelope.

6. The conductor apparatus of claim 3 wherein each of said envelopes is formed of a hollow tube of circular cross-section and said second envelope is of a slightly larger cross-section than said first envelope to provide insulative separation therefrom.
