  • Publication number: 20220010444
    Abstract: A device comprising an electrolyser, a compressor, and a membrane separating device, and to a method for changing the operating mode between normal and standby operation of said device, in the normal operation of which an electrolysis raw product comprising carbon dioxide is converted in the electrolyser into an electrolysis product containing carbon dioxide and carbon monoxide, at least one portion of which is conducted via the compressor and is fed at an increased pressure to the membrane separating device in order to obtain a retentate which is enriched in carbon monoxide and depleted of carbon dioxide compared with the electrolysis product. According to the invention, in order to change from the normal operation into the standby operation, the electrolyser is completely isolated from the membrane separating device in terms of flow and then shut down, wherein the pressure ratios in the membrane separating device are largely maintained.

  • Patent number: RE45130
    Abstract: This invention relates to a device for fastening and anchoring heart valve prostheses which is essentially formed of wire-shaped interconnected elements. The aim of the invention is to be able to be implant, in a minimally invasive manner, a device of this type via the aorta by compressing the device to make it smaller, and by extending the same at the site of implantation, whereby ensuring a secure retention and a secure sealing with regard to the aorta wall. To this end, the invention provides that for fastening and supporting a cardiac valve prosthesis, three identical pairs of arched elements are interconnected, with a configuration that is offset by 120°, by means of solid body articulations. These solid body articulations carry out the function of pivot bearings.
