  • Method and means for managing citations in documents
    Patent number: 5097418
    Abstract: One of several processes is performed for the automatic management of footnote references in printed documents and a computer-controlled display shows bibliographically correct information in long form and short form in a processing system that provides for information to be enterd, stored, analyzed, merged, and transmitted to a printing device for the creation of a printed report that contains footnotes, endnotes or embedded notes which reference a source of information in correctly-reported style.
    Type: Grant
    Filed: April 14, 1989
    Date of Patent: March 17, 1992
    Assignee: Commsoft, Inc.
    Inventors: Howard L. Nurse, Herbert G. Drake, Jr.
  • Capacitive feed for plasma reactor
    Patent number: 5006760
    Abstract: A capacitive feed is disclosed for the lower electrode in a parallel plate plasma reactor. One plate of the capacitor comprises the lower electrode or a contact to the lower electrode. The other plate of the capacitor comprises an annular member insulated from the lower electrode, or the contact. There are no RF connections directly to the lower electrode.
