Abstract: Albarran modules have an Albarran lever at a distal end of a shaft. The Albarran lever is actuatable via a toggle on a main body of the Albarran module. For this purpose, the lever is coupled mechanically to the toggle by pull wires along the shaft. In known Albarran modules, the fitting and bracing of these pull wires proves complicated and laborious. Exemplary embodiments include an Albarran module (10), a drive body (17), and a method for bracing a pull wire (21), by which method at least one pull wire (21) can be braced in a particularly simple and reliable manner. This is achieved by the fact that a tensioning means for bracing the at least one pull wire (21) is connectable to a drive body (17) of the Albarran module (10) parallel to a longitudinal axis of a shaft (12).

Abstract: An implant that can be used for the treatment of the urinary tract in a manner which is more efficient and gentler on the body. This is achieved by virtue of the fact that an implant for expanding a urethra of a person by applying a local ischemic pressure to the tissue of the urethra has a pressure means structure. This pressure means structure has at least two pressure means, wherein the implant can be introduced into the urethra with a distal end in front. In this case, each of the pressure means has a spreading element and two bracing elements, namely a proximal and a distal bracing element, and wherein the bracing elements are each articulated movably at a first end to the spreading element and movably at a second end to a central bracing means.

Abstract: A process for preparing methanol by a methanol synthesis reaction of carbon dioxide with hydrogen may involve a distillation step and a condensation step following the synthesis of a crude methanol. A volatile component and water may be separated off from a methanol-containing product stream, and a gas stream containing a volatile component that has been separated off may be discharged at least partially as offgas. At least part of the gas stream that has been separated off may be recirculated into the methanol synthesis reaction. A plant for preparing methanol can store or utilize electric power generated from renewable energy sources and provide facilities for discharging the offgas stream, which can be purified by catalytic after-combustion. Alternatively, the plant can be configured without discharge of an offgas substream, or the offgas streams are so small that they can be released without treatment into the environment at a suitable position.

Abstract: A method for operating a plant for synthesizing methanol, wherein a synthesis gas flow having hydrogen and carbon oxides is supplied to a synthesis gas compressor of the plant to increase the pressure of the synthesis gas flow. The pressure-increased synthesis gas flow is supplied to a methanol reactor arrangement of the plant for partial conversion to methanol. The plant has a hydrogen recovery arrangement which obtains an H-recycling flow including hydrogen from a recovery flow supplied from the methanol reactor arrangement, which hydrogen is converted at least in part to methanol. Upon failure of the synthesis gas compressor, the synthesis gas flow continues to be supplied to the methanol reactor arrangement for partial conversion to methanol. Following failure of the synthesis gas compressor, a line arrangement of the plant is switched such that the H-recycling flow is adjusted to compensate for a pressure loss in the methanol reactor arrangement.
