Abstract

489,704. Wireless signalling. CORK, E. C., and PAWSEY, J. L. Jan. 30, 1937, No. 2760. [Classes 40 (iii) and 40 (v)] A high-frequency transmission line 3 feeding signals from a source 4 is matched to a load 5 by means of a section of auxiliary line 6 of such impedance Z0 and length as to produce a partial match, a loading impedance Z being associated with the auxiliary line in such a manner as to afford a substantially accurate impedance match between the line and load. The Specification contains formulµ relating the characteristic impedance and length between terminals A, B, C, D of the auxiliary line and the position (#1, #2) and dimensions of the lumped impedance which may be a series or shunt element. The impedance Z may be formed by a length of line connected at the junction of the lengths #1, #2, and its position and magnitude may be varied to compensate for reactive components of the load impedance. Specification 356,085 is referred to.
