  • Patent number: 6330954
    Abstract: A can end for a two-piece beverage can including a generally flat radially extending portion; a score panel defined in the generally flat radially extending portion by an arcuate score, the score panel having a central, longitudinal axis projecting in a first axial direction and a second axial direction opposite the first direction; an annular emboss bead formed in the score panel and projecting in a first axial direction; and an annular deboss bead formed in the score panel and projecting in the second axial direction.
    Type: Grant
    Filed: August 20, 1999
    Date of Patent: December 18, 2001
    Assignee: Rexam Beverage Can Company
    Inventors: Tim L. Turner, Robert L. Hurst
  • Patent number: 5964366
    Abstract: A can end for a two-piece beverage can including a score panel defined by an arcuate score line which comprises a score groove and a score residual portion. In order to control the opening speed of the score panel, the thickness of the score residual is varied along the score line. A thickened score residual area or areas may generally be located opposite the rivet area of the can end. The remainder of the score residual may be formed having a relatively smaller thickness, thus allowing opening of the end to be accomplished without the need for excessive force.

  • Patent number: 5664009
    Abstract: A method and system is provided for performing voice mail services in conjunction with a telecommunication service network. The invention specifically discloses a method and system of updating a message count representing the number of pending voice mail messages directed to a telecommunication service subscriber. The invention also discloses a method and system of automatically notifying a telecommunication service subscriber of the number of pending voice mail messages based on the value of the message count. The invention further discloses a method and system of automatically assigning a voice mail box number to a telecommunication service subscriber upon the request of the subscriber.
    Type: Grant

  • Patent number: 4170193
    Abstract: Apparatus generates and substantially uniformly electrostatically deposits very finely divided lubricating particles onto the surface of an electrically conducting substrate. A lubricant material is sheared into droplets of various sizes. The larger particles are filtered out of a flow of particles by gravity, baffles, and other forces leaving only a cloud of extremely small particles to be deposited. Deposition occurs within a housing that includes a plurality of sections arranged longitudinally on at least one side of the substrate and includes electrode means transversely positioned in each such section. The cloud of particles is uniformly provided to each of a plurality of longitudinal sections of the substrate and permitted to drift or migrate relatively slowly between the electrodes and the substrate. The particles in the cloud are electrostatically charged by high voltage applied to the electrodes and deposited on the surface of the substrate as a uniform dispersion of spaced particles of lubricant.

  • Patent number: 4066803
    Abstract: Method for generating and substantially uniformly electrostatically dispersing very finely divided spheroidally shaped lubricating particles onto the moving surface of metal or other electrically conducting substrate. A lubricant material in its liquid state is drawn by airflow through a small venturi orifice where it is sheared into droplets of various sizes. Larger droplets are filtered out of the continuing post-venturi airflow by gravity, baffles, airflow forces and/or inertia effects, leaving only a mist cloud of extremely small spheroid particles which are then migrated within a charged plasma so as to transfer electrical charge thereto in sufficient quantities to achieve a desired uniform high charge/mass ratio and thus insure a uniform eventual electrostatic dispersion of substantially all the spheroids over the substrate surface.
