  • Apparatus for fabricating pasted electrodes
    Patent number: 6623562
    Abstract: A slurry loading apparatus for automatically loading a slurry into a substrate. The apparatus includes a pasting head. The pasting head includes a cavity that fills with slurry creating a pressure that forces the slurry onto the surface of the substrate and into the voids of the substrate. The slurry loading apparatus may include a feedback control loop that controls the rate in which slurry is delivered to the pasting head.
    Type: Grant
    Filed: November 7, 2001
    Date of Patent: September 23, 2003
    Assignee: Ovonic Battery Company, Inc.
    Inventors: Edward F. Wood, Eric Willison, Jeffrey Key

  • Portable plug-in control module for use with the service modules of HVAC systems
    Patent number: 6179214
    Abstract: A portable, preferably hand held control module for use in a heating, ventilating or cooling (HVAC) system that includes at least one subsystem that may be controlled via a service module which is located in proximity to that subsystem. The portable control module includes a plurality of manually operated keys for enabling a user to apply to the subsystem commands which are generally the same as commands which may be applied via the manually operable keys of the service module. The portable control module also includes a display assembly having one or more displays for displaying to the user information concerning the subsystem that is generally the same as that which is displayed on the display assembly of the service module.

  • Powder delivery system for electrode production
    Patent number: 6139302
    Abstract: A powder delivery system for delivering an electrode powder to a compaction device where the powder is compressed onto an electrically conductive substrate, the powder delivery system comprises a powder feed channel which is vibrated to effect powder movement therethrough and delivery therefrom. An accelerometer is coupled to the powder feed channel for measuring the acceleration of the channel as it vibrates. The actual measured acceleration is used to control the vibration of the channel.
