  • Patent number: 10784812
    Abstract: Distributed energy storage within the distribution network of an electric power network at least partially supplied by time varying and unpredictable generation sources provides smoothing of energy flow within the distribution network. The distributed energy storage may include a plurality of distributed energy storage units operating under the control of a single controller or regional controllers. The distributed energy storage units may operate as groups of units or as separate units.
    Type: Grant
    Filed: June 12, 2013
    Date of Patent: September 22, 2020
    Assignee: S&C Electric Company
    Inventors: Donald Berkowitz, Thomas Walker

  • Publication number: 20070285857
    Abstract: A power distribution protection system and method uses communications to coordinate operation of fault protection devices. Communications may be prioritized wherein messages of a lower priority are held or discarded in favor of messages of a higher priority, for example, messages indicating a fault condition. The devices may use multiple channel access schemes in accordance with a priority of a message to be communicated.

  • Patent number: 4218454
    Abstract: Novel N-sec-alkyl derivatives of norcodeine and normorphine wherein the sec-alkyl group contains either four or five carbon atoms. Specifically included are those derivatives of norcodeine and normorphine wherein the sec-alkyl group is 2-butyl, 3-pentyl, .alpha.-methylallyl and .alpha.-methylcyclopropylmethyl. The normorphine derivatives have strong agonist potency combined with strong antagonist qualities and indicated low addiction potential. The norcodeine analogs are useful as intermediates in preparing the corresponding normorphine compounds.
