  • Publication number: 20130146597
    Abstract: An easy-open metal end and a method for making same, in which a pre-score coining operation is performed, followed by an operation to form a score line. The coining step uses gentle-radius tooling designed not to crack or cut a protective coating on the metal end. Between the coining step and the score line-forming step, a paneling step is performed to pull out the loose metal generated in the coining step, such that end tension can be controlled more easily than in a conventional process. The coining operation thins the metal, so the score line can have less penetration than, and therefore can be narrower than, a conventional score line. Consequently, even if the score line does rust, it will be very small in width and thus relatively unnoticeable.

  • Patent number: 6004262
    Abstract: A visually-positioned electrical monitoring apparatus includes an electrical assembly comprising an elongate, flaccid dielectric body having at least one electrical contact, a passage and an open distal end. An endoscope extends through the passage and has its distal end substantially in registry with the distal end of the body. A method for placing an electrical monitoring assembly to coact with human tissue at a target site includes providing the aforedescribed monitoring assembly, extending an endoscope into the passage, aligning the distal end of the endoscope with the distal end of the body and visually guiding the assembly to the site.
