Patent DE-4230300-A1 (DE)
Inventor: KUEHNLE GOETZ DR
IPC: G02F1/335
Filed: 1992-09-10
Abstract: The proposal is for an integrated opto-acoustic component to shift light frequencies, in which two separated light guides (11, 12) have an optical coupling region (13) formed in the manner of a directive coupler in which the two light guides (11, 12) are at a short distance from each other to generate an optical coupling. The acoustic waves (19) from a sound generator extend longitudinally over the coupling region (13). The two light guides (11, 12) have different diffusion constants for light. If, for example, light in mode a is radiated into light guide (11) and if the sound generator (14) is switched on, the photons of mode a are scattered on the photons of the sound waves and converted into mode b of light guide (12), where they can diffuse. This produces a frequency shift. The opto-acoustic component thus contains a frequency shifter and also a coupler which can be used as a beam divider and/or optical switch.

Title: Balanced line for UHF one to four impedance transformation - modifies half wave phasing line to quarter wave line for insertion into symmetric antenna system to provide linear impedance transformation for all antennae
Inventor: MENZLEWSKI VICTOR
IPC: H01Q5/335
Filed: 1992-07-13
Abstract: The line has two stretched parallel quarter wavelength coaxial conductors open on two sides. The conductors are of the same resistance and their inner conductors are connected in series. The tubes are mechanically connected and can be embedded in a carrier mast. Instead of tubular conductors with air dielectrics, loss adjusted coaxial cables can be used.

The same function is carried out by a screen around a quarter wave phasing line in the form of a round or rectangular outer conductor with air insulator or the cladding of a two-line cable. Using a flexible parallel three-line flat cable, the inner conductor and coax. supply cable are connected. ADVANTAGE - Has low loss and is simple to install.
