The meter is operated according to a method for the determination of meter readings and for the wireless transmission of electrical energy. The shape of the readout unit antenna is identical to the shape of the metering unit antenna, wherein the congruent and predefined positioning of the readout unit antenna ensures an effective wireless energy supply to the metering unit by electromagnetic radiation through the readout unit, and, independently thereof, a stable wireless data coupling for the determination of meter readings between the metering unit and the readout unit.

Abstract: An apparatus for the mixing conveying of fluids with heat exchange includes a housing with installations that each include a first hollow structure for conveying a first fluid while a second fluid is able to flow around the first hollow structure. The second fluid flows along a main flow direction which is substantially disposed along the longitudinal axis of the housing. A second hollow structure is provided through which the first fluid can flow and which can be flowed around by the second fluid with the second hollow structure being arranged cross-wise with respect to the first hollow structure. The hollow structures have a flow cross-section with a first width B1 and a second width B2, with B1/B2 being larger than one and B1 oriented normally to a plane which contains the longitudinal axis of the housing or a line parallel to the longitudinal axis and an axis of the hollow structure.

Abstract: The static mixer for a low viscosity fluid contains inbuilt devices effective for mixing, which are arranged in a pipe or in a container conducting the fluid. The inbuilt devices include structure elements in the form of flat, folded or curved sheet metal-like flow obstacles to form primary flow obstacles to achieve a flow of the first order. The structure elements are geometrically modified at surfaces and/or at edges so that local flows of the second order can be induced which are superimposed on the flow of the first order and so improve the mixing quality. Radial and axial inhomogeneities in the fluid are namely better compensated than by the flow of the first order.

Abstract: The pipe member (1) having an infeed point (2) for an additive (20) includes a pipe wall (11) and a static mixing element (12). The infeed points are provided for introducing the additives into a flowing, low viscosity fluid (10). The static mixing element consists of a pair of vanes (5a, 5) and of a third vane (6). The vane pair (5), which forms a restriction deflecting the flow (10′) of the fluid, is formed with substantially mirror symmetry with respect to a central plane (15) extending in the direction of the flow. The third vane is arranged in a crossing manner with respect to the vane pair and in a lying manner in the region of the central plane. It has a rear side (60) with respect to the flow which extends from a base at the pipe wall to a downstream end. Each infeed point is arranged at the rear side of the third vane.

Abstract: The mixing element (2) is provided for a flange transition (10) in a pipeline (1) and can be mounted between two flanges (11, 12) of the pipeline. It comprises a mixing-active structure (25) which is formed by one or two vanes (25a, 25b) within a ring (20). Two mutually inclined planes (21, 22) can be defined, with the one vane being arranged on the one plane or the two vanes being arranged on the two planes. The two planes intersect at a crossing axis (23). Closed sub-surfaces (52, 51′) as well as open pieces of surface (51, 520, 521, 522) of vanes form a surface pattern (5) which is formed asymmetrically with respect to the crossing axis.

Abstract: A telecommunication system provides voice and data communications over a conventional telephone line that can be dynamically switched from voice mode to data mode during a single conversation. Each station includes a telephone for voice communications and bypass relay means for selectively connecting the telephone to the telephone line in voice mode and disconnecting the telephone while operating in data mode. Prior to transmitting data, the originating station first transmits a start signal over the telephone line that includes a rate signal indicating one of the several possible data transmission rates. If a station detects a start signal transmitted by a remote station, a microcontroller directs the bypass relay means and modem to automatically switch from voice mode to data mode in preparation for receiving data from the originating station.

Abstract: Disclosed herein is a surgical stockinette for covering and encasing a body extremity such as an armor leg to isolate and protect the extremity during surgery. The stockinette has a generally tubular-shape and is made from a composite material defining a length and a width with the length being longer than the width. The stockinette defines an interior surface and an exterior surface with the tubular-shaped structure defining an open end and a closed end separated by the length. The interior and exterior surfaces are joined circumferentially to one another along substantially the entire length of the tubular-shaped structure. The interior surface is formed from a fibrous material and the overall structure is liquid impervious and circumferentially expandable from a first circumference to a second and larger circumference. Due to the materials and nature of construction, the stockinette of the present invention provides a form-fitting design which is easy to don and remove.
