Abstract: Embodiments of the invention include a combiner for an RF amplifier comprising wiring and a transmission line transformer. The transmission line transformer may include a ferrite core having a hole defined therein; a coaxial cable having a first dielectric constant and routed through the hole of the ferrite core; and a stripline having a second dielectric constant and routed around the ferrite core. In some embodiments, an electrical length of the stripline is matched to an electrical length of the coaxial cable. The electrical length of the coaxial cable may be defined by the first dielectric constant and the electrical length of the stripline may be defined by the second dielectric constant.

Abstract: The present invention is directed to a method for the preparation of ruthenium indenylidene carbene catalysts of the type (L)(L?)X2Ru(II)(aryl-indenylidene). The method comprises the steps of reacting the precursor compound Ru(PPh3)nX2 (n=3-4) with a propargyl alcohol derivative in an cyclic diether solvent such as 1,4-dioxane at temperatures in the range of 80 to 130° C. and reaction times of 1 to 60 minutes. Optionally, additional neutral electron donor ligands such as PCy3, phobane ligands or NHC ligands are added to the reaction mixture for ligand exchange. The method includes a precipitation step for purification, after which the product is isolated. The ruthenium-indenylidene carbene catalysts are obtained in high purity and are used as catalysts for metathesis reactions (RCM, ROMP and CM) and as precursors for the synthesis of modified ruthenium carbene catalysts.

Abstract: A magnetic position sensor consisting of a non-electroconductive, non-magnetic carrier on which a resistive layer is arranged, in addition to a pick-off layer which is located at a distance from the resistive layer and at least partially overlaps the same. The distance between the two layers is selected in such a way that contact is established between the two layers by a magnetic device that can be moved along the overlapping regions of the resistive layer and the pick-off layer. The pick-off layer is a film which consists of a ferromagnetic material and is electroconductive at least on one side. The pick-off layer is a film which consists of a ferromagnetic material and is electroconductive at least on one side.

Abstract: The invention relates to a magnetic position sensor (1) consisting of an electrically non-conductive, non-magnetic carrier (2), on which a resistive layer (3) and a tapping layer (4), which lies at a distance from and at least partially overlaps said resistive layer, are arranged. The distance is selected in such a way that under the action of a magnetic unit (5) that is moved along the regions of the resistive layer (3) and the tapping layer (4) lying above one another, said layers (3, 4) come into contact with one another. According to the invention, the tapping layer (4) is a foil consisting of an amorphous metal, upon which the force of the magnetic unit (5) acts.
