specification of letters l'atent. Patented Apr. 19, 1910. Application filed July 14, 1909. Serial No. 507,473.
To all whom. it may concern:
Beit known that I, MINOR M. DAVIS, a citizen of the United States, residing in the city of New York, boron h of Brooklyn, county of Kings, State of dlew York, have made certain new and useful Improvements in Anti-Induction Devices for Electrical Conductors, of which the following is a This invention relates to means for preventing induction between separated, substantiall parallel conductors.
The ject of this invention is to prevent the harmful action of conductors carrying alternating impulses of considerable strength,
' such as are used for power purposes, upon conductors within inductive distance of such conductors employed for signaling purposes,
' this reaction so as to compensate or neutralize the action ofthe disturbing source on Stated specifically a positive impulse in the disturbing conductor induces a negative impulse in the circuit conductor and the idle conductor, the negative impulse in the idle conductor re-acts tending to enerate a positive impulse in the circuit con uctor. By varying the constants of the idle conductor that is, the resistance or capacity or both, the im ulses from the idle conductor may be me e to counteract the disturbing impulses in the circuit conductor.
The accompanying drawing illustrates the from each other, theconductors k are used attained.
for signaling purposes as, in telegraphing; and are included in circuit with telegra h instruments t. There are also a series 0 what may be called idle conductors w, these are substantially like the conductors is but are used for compensating purposes. They are connected together, as shown, at one end, and to a grounded adjustable resistance '1'. At the opposite terminal they are connected through. an adjustable condenser a and may be connected directly with the ground Let us assume a positive impulse in the conductor (1, this induces a ne ative impulse in the conductors in and w. I the resistance or capacity, or both, of the conductors w 1 pro erly adjusted said negative impulse in con uctors w is so lncreased in its efiect ,upon the conductor k as to neutralize the inductive impulse'of the conductor a5. To secure this result the resistance of the conductor w is varied ,by moving the switcharm 8 over the contacts 6, 7, 8, etc., and the capacity of the condenser n is varied by moving switch-arm a over the contacts 11 to 15 until the ropcr resistance and capacity is he conductor 70 may he say, 100 miles lon and the conductor 'w maybe 20 miles or less but y establishing the con stants of conductors 'w, that is the resistance, or capacity, of said conductors at a determinable point an effect is produced in conductors 'w that is efficient-to compensate for the eifect of the disturbing cause on conductor k. In other words the induction of conductor d on conductor to and conductor k is neutralized by making the constants of 10 effective forgsuch purpose.
What I claim and desire to secure by Letters Patent is:
1. Ananti-inductive arrangement of conductors in inductive relation with respect to a conductor carrying disturbing current 1 impulses, consisting of the combination of an insulated conductor in circuit with suit-
