Title: Werner Appel: Innovator in Electrotechnical Solutions
Introduction
Werner Appel is a notable inventor based in München, Germany. He has made significant contributions to the field of electrotechnical solutions, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is a Bandpass Filter. This invention includes a series of waveguide resonators positioned along a common longitudinal axis, defining at least a first resonator and a last resonator. Adjacent resonators are mechanically linked by a common coupling plate made of sheet metal, which features coupling slots for electrically coupling the resonators. The first and last resonators are closed by an end plate of sheet metal. Each resonator is formed from a longitudinally welded sheet metal, and the end plates and the common coupling plate are equipped with circumferentially spaced tabs that are bent to extend along the adjoining waveguide. These tabs are welded to the waveguide, while the joints between the end plates and the common coupling plate, and the adjacent waveguides, are soldered.
Another significant patent is the Sealed Cable Connector. This invention includes a plug or coupler with a sleeve that extends over the cable end and surrounds a strain relief ring, contoured annular seal, and a thrust collar. The seal consists of an outer ring and an inner ring connected by a radial bridge. During assembly, the thrust collar and the strain relief ring work together so that when the thrust collar is axially displaced toward the strain relief ring by a screw plug turned into the sleeve, the bridge is sheared off. This action compresses the inner and outer rings within their respective spaces while the thrust collar presses the outer cable conductor against a contacting face of the sleeve.
