Abstract
Abstract A delay line device comprising a first group of coils arranged in a first straight row, and a second group of coils arranged in a second straight row which is parallel to the first row. The second group of coils are generally deviated toward the input side of the delay line with respect to the first group of coils. Electrical connection is provided between the successive coils in the first and second groups. An input is imparted to the first one of the coils in the first group as viewed from the input side, and an output is taken from the last one of the coils in the second group also as viewed from the input side. The axial direction of each of the coils in the first and second groups is so selected that the couplings between the most adjacent ones of the coils in the first and second groups are positive and that the couplings between the coils in each of the groups are negative. Furthermore, each of the coils in the first and second groups is provided with a tap, which is grounded through a capacitor.

Claim 1
Independent Claim
347 words
A delay line device comprising a first group of coils arrayed in a first straight row and equally spaced apart from each other, and a second group of coils arrayed in a second straight row and equally spaced apart from each other, said first and second straight rows being in substantially parallel spaced relationship with each other, such that one of the coils in said first group is located at one end of said first straight row and is adapted to serve as an input coil and one of the coils in said second group which is located at that end of said second group which corresponds to the other end of said first straight row is adapted to serve as an output coil, said first and second groups of coils being arranged so that said input coil in said first group is located at a position corresponding to a position between the coil in said second group which remotest from said output coil and the coil in said second group which is most adjacent to said coil remotest from said output coil and said output coil in said second group is located at a position corresponding to a position between the coil in said first group which is remotest from said input coil and the coil in said first group which is most adjacent to said coil remotest from said input coil, wherein electrical connection in zigzag form is provided between said first and second groups of coils so that said input coil in said first group is connected to that coil in said second group which is remotest from said output coil, the last-named remotest coil being connected to the coIl in said first group which is most adjacent to said input coil, and finally that one of the coils in said first group which is remotest from said input coil is connected to said output coil in said second group, a tap being provided on each of the coils in said first and second groups, each of said taps being grounded through a capacitor.
