Title: Microwave and MM wave mixer - has pair of nonlinear solid state elements, bandpass filter for reactive loading of output terminals
Inventor: BERGMANN GUENTHER DIPL ING
IPC: H03B7/14
Filed: 1980-03-19
Abstract: A microwave and millimetre wave mixer consists of two non-linear elements connected back-to-back. The elements are formed by solid state dipoles, where the pump frequency is equal to half the difference between the input and output frequencies. The waveguide used has dimensions related to the frequency of the pump energy, the input and the output energy. The pump energy and the input energy can be propagated along the waveguide. The output energy is absorbed. The difference between the quadruple of the pump energy frequency and the frequency of the input energy or output energy is reactively loaded. The waveguide contains a bandpass filter upstream of the non-linear element.

Abstract: A main compressed-air jet nozzle (3) blows the weft thread (1) into a guide channel penetrating into a shed and consisting of slotted rings (7) arranged next to one another, from where it is then carried further into the warp shed (10) by air jets from a multiplicity of auxiliary nozzles (13a to 13i). At the same time, the conveying force of the air jets issuing from the auxiliary nozzles increases at an increasing distance from the main nozzle, in that the quantity of air issuing from the individual auxiliary nozzles is increased correspondingly. As a result, the consumption of compressed air can be reduced, whilst the highest possible efficiency is ensured. <IMAGE>

Title: Solar collector design
Inventor: HACHT GERHARD VON DIPL ING
IPC: F24S23/77
Filed: 1981-03-11
Abstract: The absorber in the compression solar collector with a four-fold solar plane mirror collecting surface consists of a housing made from glass or plastic plates which are transparent to solar rays and which are situated opposite one another in a plane-parallel fashion at the light-wave separation and form a "Fabry-Perot Resonator" liquid LASER. Solar elements sensitive to light on both sides are aligned in the absorber housing with their narrow edge towards the beam-capture path. They are illuminated on both sides on their wide surfaces by the LASER liquid, resulting by comparison with conventional solar elements in an increase in power given the use of the same solar element material, since the gains from the double-sided use of the solar plate material, the beam compression and the gain in the intensity of illumination by the liquid LASER are added together. In addition, the thermal circuit can be used in the normal way by the absorber.
