  • Patent number: 9053403
    Abstract: A device for identifying a metal substrate present in a strongly metallic environment that may also be dusty. The device includes a passive radio-frequency identification (RFID) label, a label carrier suitable for being attached to the metal substrate and to position the label at a distance therefrom, and a RFID reader having an antenna that includes, as an induction loop, two sections of a coaxial cable having a substantially identical length and each including a metal core and a metal pleat surrounding the core, the two sections being linked together, on the one hand, at one end thereof by connecting the core of one to the pleat of the other and conversely and, on the other hand, at the other end thereof by connecting only the pleats together, the cores thereof being separated at said other end.

  • Publication number: 20110232111
    Abstract: This can opening machine comprises a lower guide ring to center the top of the single-piece can, comprising a centering chamfered face and an upper stop face. A piston arranged in the tool for cutting out the can lid is pushed downwards by a spring extending low enough to separate the cut out lid from the tool. The lid remains in the can during turning and content emptying operations.
