Abstract: 635,707. Secret transmission. PATELHOLD PATENTVERWERTUNGS- & ELEKTROHOLDING AKT.-GES. Feb. 4, 1947, No. 3319. Convention date, Feb. 4, 1946. [Class 40 (iv)] The voice frequency spectrum from each of a number of circuits GK1, 2, &c. is divided into a number of sub-bands which are distributed according to a predetermined plan over a number of transmission channels VK1, 2, &c. so that each channel includes a complete spectrum. Signals, e.g. 250-2750 cycles, applied to GK1, GK2, &c. are fed into the modulators Me, the local oscillators of which have frequencies varying in 500 cycle steps and portions of the lower sidebands are selected by filters Fe having a common pass band of 2750-3250 cycles. The sub-bands thus obtained after cross switching in the permutating switch PS are modulated in the modulators Ma which have their associated oscillators arranged to shift the sub-bands to again occupy the normal speech frequency range. Signals which have been scrambled' in the same manner by similar apparatus at the distant end are unscrambled in their passage through the equipment in the reverse direction to that described. Noise frequencies may be sent over any speech channel not in use.

Abstract: 572,981. Thermionic valves. BULL, C: S. March. 5, 1940, No. 4072. [Classes 39 (i) and 40 (iii)] Conductors passing through the wall of a high-frequency valve are altered in shape when they pass through the wall to neutralize changes in capacity produced by the difference between the dielectric constant of the material of the envelope and that of air or vacuum. Fig. 1 shows a strip conductor connected to a valve grid 11 and to the interior conductor 16 of a coaxial line, the cathode and the outer conductor being connected by a similar parallel strip. When these strips pass through the wall of the envelope they are narrowed, as shown at 18, for the purpose described. Alternatively, they may be bent outwards where they pass through the wall 8. Fig. 5 shows coaxial conductors 19, 20, thinned where they pass through the walls. Fig. 6 shows coaxial conduotors connected by a conical seal 22 and thinned in the portions opposite the seal. As the effect of the seal is not uniform at different points, the reduction in the conductors is varied accordingly or the thickness of the seal may be varied to compensate for the change in its diameter.
