  • Patent number: 11612264
    Abstract: A modular track system for hanging a curtain, the track system consisting of modules or sections with attachments and accessories designed to adjust to varying environments and specifications. Track shape and length are adjusted by specifying various combinations of the specialized components created as part of the system. Complementing the track system is a curtain with integrated loop fasteners which allows the curtain to be attached and removed without removing the track. The system further preferably includes a side support for use in attached the track to a fixed support in the environment, and a guiderail on the side of the track on one or more track sections, the track and curtain all being coordinated to form an efficient and improved curtain hanging system.

  • Patent number: 9511024
    Abstract: The present invention provides new amino lipids and a convenient method for synthesizing these compounds. These (cationic) amino lipids have good properties as transfection agents. The method is an economic versatile two step synthesis allowing the preparation of various amino lipids thus leading to the assembly of a combinatorial library of transfection agents. Moreover, the present invention provides lipid particles (liposomes) containing said amino lipids and their use for delivering bioactive agents into cells. The invention encompasses also the use of lipid particles containing the cationic amino lipids as medicament.
