Capacitive rotatable coupler

TL;DR: In this paper, a tuned split coaxial ring rotary joint for a single channel or multichannel RF transmission line is described, which has a stator half in operable association with a rotatable rotor half.

TL;DR: An electromagnetic interference shield isolator as mentioned in this paper is a coupling device for coupling the shielded cables having a capacitor built into the coupler assembly to isolate the shield cables from each other with respect to both DC and RF interferences.

TL;DR: In this paper, an assembly for electrically coupling a first coaxial cable to a second cable for rotation relative to one another is described and generally comprises a pair of sub-assemblies which electrically connect the inner and outer conductors of the first cable to respective inner and inner conductors on the second cable while substantially eliminating frictional wear therebetween.

TL;DR: In this paper, the authors present a phase shifting device which enables the phase of a wave to be readily and rapidly varied without altering the magnitude of the wave's phase. But it is an object of the invention to provide a phase shift device which shall permit the phase shift without altering a wave's magnitude.

TL;DR: In this article, a radio receiving device arranged to receive horizontally polarized waves is described, which is a continuation in part of an earlier application, Ser. No. 354,539, filed August 28, 1940, now Patent No. 2,266,630, issued December...

TL;DR: In this article, the directional antenna items for ultra high frequency operation for use with both transmitting and receiving sets are described. But their main purpose is to improve the performance of directional antenna for UHF wave length operation.

TL;DR: In this article, the authors introduced the concept of electrical devices of the type adapted to operate at frequencies so high that the dimensions of the devices are greater than or not very much less than the wavelength corresponding to the frequency of operation.
