  • Chalcogenide glass-ceramics with photoelectric properties and method for the manufacture thereof
    Patent number: 9492815
    Abstract: Chalcogenide glass-ceramic having, for example, the following composition GeSe2—Sb2Se3—CuI, this glass-ceramic comprising at least one crystalline phase, characterised in that the crystallisation rate and the dimensions of the crystals in the crystalline phase are such that the crystals are substantially in contact with each other in such a way that this crystalline phase has an electrical conductivity greater than or equal to 10?4 s·cm?1 which increases under lighting due to the creation of charge carriers within the crystalline phase.
    Type: Grant
    Filed: June 19, 2013
    Date of Patent: November 15, 2016
    Assignees: Centre National de la Recherche Scientifique, Universite de Nantes, Universite de Rennes 1

  • Compressing device for plastic bottles
    Patent number: 7290486
    Abstract: A compressing device for plastic bottle uses a pair of plates which are strapped on each side of a bottle. The straps are tightened as the bottle's content is used up. The plates are shaped in such a way so as to reduce crimping on the bottle. Optional accessories such as a saddle to hold the plates on the side of the bottle while installing; a stand to hold the bottle upright; and a handle to facilitate pouring are available.
