Abstract
Abstract A mutual inductance adjusting circuit employable with a network comprising at least two series-connected inductors and a shunt capacitor or capacitors. A compensating inductance element or elements are provided through which said shunt capacitor or capacitors are grounded, whereby the mutual inductance between the series inductors is changed by a value equal in magnitude but opposite in sign to the compensating inductance. Thus, the mutual inductance between the series inductors can be adjusted by shiftably selecting the value for the compensating inductance.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
A mutual inductance adjusting circuit for a network including at least one inductor-capacitor combination unit comprising: A. at least first, second, and third inductors connected in series with each other; B. at least first and second capacitors, said first capacitor being connected at one end to the connection point between said adjacent first and second inductors and said second capacitor being connected at one end to the connection point between said adjacent second and third inductors, and C. a compensating inductance element through which said capacitors are connected at the other ends thereof to a reference potential point, whereby the effective value of the mutual inductance at least between said first and third inductors is changed by a value equal in magnitude but opposite in sign to the inductance of said compensating inductance element.
Claim 2
Dependent Claim
134 words
A mutual inductance adjusting circuit for a network including at least one inductor-capacitor combination unit comprising: A. at least first, second, and third inductors connected in series with each other; B. at least first and second capacitors, said first capacitor being connected at one end to the connection point between said adjacent first and second inductors and said second capacitor being connected at one end to the connection point between said adjacent second and third inductors, and C. a compensating inductance element through which said capacitors are connected at the other ends thereof to a reference potential point, whereby the effective value of the mutual inductance at least between said first and third inductors is changed by a value equal in magnitude but opposite in sign to the inductance of said compensating inductance element.
Claim 3
Dependent Claim
86 words
A mutual inductance adjusting circuit according to claim 1, wherein said network constitutes a delay line comprising a plurality of said inductor-capacitor combination units which are connected in such a manner as to share one inductor between the respective adjacent inductors of said uniTs and wherein said inductors are inductively coupled to each other, characterized in that said compensating inductance elements are selected so as to make negative the effective value of the mutual inductance between said inductors between which an odd number of inductors exist.
Claim 4
Dependent Claim
34 words
A mutual inductance adjusting circuit according to claim 2, including a compensating inductance element for reducing the effective value of the mutual inductance between the inductors between which an even number of inductor exist.
Claim 5
Dependent Claim
15 words
A mutual inductance adjusting circuit according to claim 1, wherein said compensating element is variable.
Claim 6
Dependent Claim
26 words
A mutual inductance adjusting circuit according to claim 1, wherein said series-connected inductors are formed by a continuous length of wire wound on a coaxial bobbin.
