Abstract: A coupling element connectable to a string of one or more pipes, for example, a drill string of one or more pipes or drill pipes is provided. The coupling element is configured to excite, responsive to a data signal fed to the coupling element, an electromagnetic wave in the string. The coupling element comprises a feed portion at a first end of the coupling element, the feed portion to receive the data signal, a first electrically conductive portion extending from the feed portion towards a second end of the coupling element, the second end to be connected to the string for forming an electrically conductive connection between the first electrically conductive portion and the string, and a second electrically conductive portion extending from the feed portion towards the second end of the coupling element. The first and second electrically conductive portions are arranged so as to define a waveguide. The waveguide expands in a direction from the first end towards the second end.

Abstract: A method of making a spunbond fleece from continuous filaments wherein at least some of the filaments produced have natural crimp. The filaments are deposited in the deposition station of a conveyor creating a filament mass and the conveyor transports the filament mass toward a consolidating device. A gas stream is produced that flows along the upper surface of the filament mass in the travel direction of the filament mass.

Abstract: An epoxy resin composition prepared from a dihydroxydiphenyl-cycloalkane compound to form a diglycidyl ether of dihydroxydiphenyl cycloalkane compound which may be useful for making various products including, for example, powder coatings, composites and electrical laminates.

Abstract: A construction concept for high-pressure sensors is provided, which enables simple and economical production of reliable high-pressure sensors even for pressure ranges above 2200 bar. A high-pressure sensor of this kind encompasses a sensor element for pressure sensing and a connector piece for coupling the sensor element to a system to be measured. A diaphragm is embodied in the base element of the sensor element, and a pressure conduit is embodied in the base element of the connector piece. The sensor element is mounted on the connector piece so that the pressure to be measured is able to act upon the diaphragm via the pressure conduit. Firstly the base element of the sensor element is mounted on the base element of the connector piece, a full-area connection being generated between the mounting surfaces of the two base elements. Only thereafter is the pressure conduit configured in the connector piece, and the diaphragm of the sensor element exposed.

A high-pressure sensor of this kind encompasses a sensor element for pressure sensing and a connector piece for coupling the sensor element to a measured system, a diaphragm being embodied over a blind opening in the base element of the sensor element, a pressure conduit being embodied in the base element of the connector piece, and the sensor element being mounted on the connector piece in such a way that the diaphragm can be impinged upon, through the pressure conduit that opens into the blind opening, by a measured pressure. The blind opening in the base element of the sensor element is embodied, at least in one portion, in a manner tapering conically toward the diaphragm, and that end of the pressure conduit which faces toward the sensor element is tubular in shape.
