Title: An improved wall insulation system and a method of installing the same
Inventor: WESTRA GREGORY
IPC: E04C2/288
Filed: 2012-01-13
Abstract: The embodiments of the invention includes a retrofitting system for the insulation of existing interior walls such as basements; a retrofitting system for the insulation of exterior walls of a structure such as a home needing further insulation without a convenient or economical method to do so within the interior walls, the inclusion of insulation within the concrete walls of a structure constructed by the tilt-up construction method and a use of elements of the insulated wall system to effectively insulate and provide continuous studding in a conventional "cast-in-place"  concrete wall assembly, subsequent to placing concrete.. The insulated wall systems of these embodiments provide an economical and efficient method of providing the installation of insulation panels to each of the walls described. The insulation panels are generally of a foam structure supported by connecting and/or corner studs. The connecting studs and corner studs are of a unique design that are easily fastened to an existing wall or made part of a Tilt-up Wall system or a "cast-in-place"  system. In addition to supporting the Insulation panels, the studs are structured to provide a moisture gap between the insulation and the exiting wall to which they are mounted. The connecting stud and corner studs also provide for wire chase areas for power distribution with a wall system.

IPC: A61B17/062
Filed: 2010-07-28
Abstract: A system for forming a purse string suture, including a suture applicator having a proximal handle having a suture spool mounted thereon or in an internal chamber. A length of suture is partly wound on the spool, and a hollow suture needle extends from a distal end of the handle and contains a free end of the length of suture. The suture needle projects distally from the handle in a helical shape and terminates in a sharp distal tip with an opening in one side close to the distal tip. The free end of the length of suture may extend out of the distal tip and back into the hollow suture needle through the opening. The suture needle may have a deflection segment adjacent the distal tip that is more flexible than the rest of the helical distal portion of the suture needle. A linear hollow pivot shaft extends from a distal end of the handle substantially along an axis of the helical distal portion of the suture needle. The pivot shaft has a blunt tip with a substantially larger radial profile than the shaft to prevent puncturing tissue.

La commande par MLI est modifiée pour rendre conducteurs successivement et sans commutation les interrupteurs de puissance de cette ou chaque autre branche (101a) lorsque, en valeur absolue, l'intensité du courant de phase concernée (Ia) est supérieure ou égale à un seuil compris entre 80 % et 120 % de (n-1) Imax/n où n est le nombre d'onduleurs et Imax est (Intensité maximale du courant de phase. On peut ainsi conserver une génération de tension sensiblement sinusoïdale sur chaque phase tout en évitant un surdimensionnement des interrupteurs de puissance pour qu'en cas de défaut ils puissent commuter des courants d'amplitude plus élevée qu'en fonctionnement normal.
