  • Publication number: 20210020975
    Abstract: Described herein are systems and methods for the management and control of electrolyte within confined electrochemical cells or groups (e.g. stacks) of connected electrochemical cells, for example, in an electrolyzer. Various embodiments of systems and methods provide for the elimination of parasitic conductive paths between cells, and/or precise passive control of fluid pressures within cells. In some embodiments, a fixed volume of electrolyte is substantially retained within each cell while efficiently collecting and removing produced gases or other products from the cell.

  • Patent number: 6891695
    Abstract: A compact tape drive for reading and writing data on single reel magnetic tape cartridges. The compact tape drive has a tape threading mechanism that extracts the leader block from the magnetic tape cartridge and threads the leader block into a takeup reel that is located juxtaposed to the loaded magnetic tape cartridge. A separate magnetic tape wrap mechanism having a plurality of cooperatively operative tape wrap arms is also provided to position the magnetic tape around a set of tape guides and the read/write head. The magnetic tape wrap mechanism functions both to thread the magnetic around the takeup reel, spanning the space in front of the read/write head, and then to wrap the magnetic tape around the read/write head. In addition, the tape elevator, electronics and other standard tape drive assemblies are included in a predefined volume.

  • Patent number: 6441990
    Abstract: The present compact tape drive for reading and writing data on single reel magnetic tape cartridges that functions to implement the tape drive in a minimum predefined volume. The compact tape drive comprises a tape threading mechanism that extracts the leader block from the magnetic tape cartridge and threads the leader block into a takeup reel that is located juxtaposed to the loaded magnetic tape cartridge. The read/write head is located adjacent to the takeup reel and the loaded magnetic tape cartridge. A separate magnetic tape wrap mechanism comprising a plurality of cooperatively operative tape wrap arms is also provided to position the magnetic tape around a set of tape guides and the read/write head. The magnetic tape wrap mechanism functions both to thread the magnetic tape around the takeup reel, spanning the space in front of the read/write head, and then to wrap the magnetic tape around the read/write head.
