  • Shear stress sensitive liposomes
    Patent number: 11904051
    Abstract: A liposome vesicle comprising a membrane consisting of 1,3-diheptadecanamidopropan-2-yl(2-(trimethylammonio)ethyl)phosphate surrounding a volume comprising a pharmaceutical drug or contrast agent. The vesicle is mechanosensitive at body temperature and at physiologically or pathophysiologically relevant shear stress.
    Type: Grant
    Filed: January 31, 2019
    Date of Patent: February 20, 2024
    Assignees: Universität Basel, Universität Freiburg

  • Connection area between housing parts of a vacuum interrupter, and a vacuum interrupter having a connection area of this type
    Patent number: 6930270
    Abstract: The aim of the invention is to optimize, in vacuum interrupters, the connection area (12, 13, 14) between housing parts (2, 3, 4, 5), which are coaxially assigned to one another, with regard to the complexity of production for centering measures and with regard to the execution of the soldering process. To this end, a ring-like discoidal centering means (15) is used, which is made of a silver-coated copper and which comprises centering lugs (18) located on a tubular flange (17) that is arranged on the inner periphery of the centering means. Said centering lugs extend in an axial direction of the coaxial assignment and are provided in the form of tabs that point toward the ring-like discoidal area (24) of the centering means. The centering means is thereby overlapped by a tubular copper part, which is joined to the centering means and which serves as a shielding (10) inside the vacuum interrupter.
