Abstract: A microwave module 1 for a fill level measuring device 2 operating with the runtime method, has a chip for generating and/or receiving microwave signals and a carrier element. To provide an advantageous as possible microwave module, the chip is located in a cavity 9 of the carrier element 8.

Abstract: A method and device for determining a velocity of a flowing medium that allows an as high as possible measuring accuracy without requiring a complicated measuring construction is achieved in that a vortex is generated in the medium and an electromagnetic signal is emitted into the medium. Then, the permittivity of the medium is determined and the velocity of the medium is determined using the permittivity measurement.

Abstract: A method for determining the fill level of a medium, wherein a transmission signal is transmitted, a return signal is received, and the return signal is evaluated in view of the process variable in a manner which allows a general and flexible handling of interfering signals in the received signals. This result is obtained by filtering at least one of the return signal, a signal derived from the return signal and an envelope curve formed from the return signal into at least one sub-signal, and using said at least one sub-signal for evaluating the return signal for at least determining the fill level.

Abstract: A microwave window for the spatial, pressure-impervious and diffusion-impervious separation and microwave connection of a first space from/to a second space, and a level-measuring system that works according to the radar principle, is provided with a barrier that has two opposite sides and is at least partially permeable to microwaves. To provide a microwave window that makes possible a reliable sealing of a process space and exact measurement, the microwave window has the barrier designed as a disk on at least one side of which at least one plano-convex dielectric lens, which has an essentially homogenous body.

Abstract: A heat exchanger for cooling reaction gas. A cooled tube receives hot reaction gas from a hot, uncooled tube. The cooled tube comprises a cooled inner tube and a tubular jacket that extends about the inner tube. A tubular connection is disposed between the uncooled and the cooled tubes, and includes a fork-shaped inlet head via which the inner tube is in communication with the uncooled tube. The inlet head is provided with an outer tubular section and an inner tubular section between which is disposed an intermediate space filled with heat-insulating material. The outer tubular section is connected to the tubular jacket. The inner tubular section is spaced slightly axially from the inner tube and is provided with an edge region that juts outwardly and is spaced slightly axially from the inner tube, this slight axial spacing being equal to or less than a maximum thermal expansion of the inlet head.

Abstract: A brake actuating unit for actuating a motor vehicle braking system of the “brake-by-wire” type having a brake booster. In order to provide a brake actuating unit for actuating a motor vehicle braking system of the “brake-by-wire” type, which on the one hand fulfills the statutory requirements care and which on the other hand is inexpensive to produce, it is proposed according to aspects of the invention, that the brake booster be provided as a travel-controlled brake booster, so that when not in the “brake-by-wire” operating mode the brake pedal is decoupled from feedback forces of the brake actuating unit, and the return force is simulated by the pedal travel simulator even when not in the “brake-by-wire” operating mode.

Abstract: A lighting device (30) comprises a side-light light guide 1? located in a support (2) that has an elongate opening for the passage of light emitted by the light guide. The support (20) is shaped to provide contact edges (24) and the only physical engagement between the support and the light guide is along those contact edges. The support also has planar surfaces internal positioned adjacent, and parallel to, planar surfaces (15) in the light guide to retain the light guide in the required orientation in the support. To enhance the flexibility of the support, in some embodiments only part of the support is continuous along the whole length of the support.

Abstract: A float for displaying the fill level of a medium (3) in a container (2), wherein the float (1), in the intended use, is guided by the wall of the container (2, 4) and is suitable for reflecting electromagnetic waves emitted from a transmitter (5) toward a receiver (6). The float has improved electromagnetic wave reflecting characteristics regardless of whether or not the float is tilted in that, in the intended use, at least the end of the float facing the transmitter (5) is a reflector (20) for reflecting electromagnetic waves to the receiver (6) and that a field attenuation structure (8) is located behind the reflector (20) from the perspective of the transmitter (5) in such a manner that electromagnetic waves interacting with the field attenuation structure (8) are attenuated.
