  • Electrode passivation
    Publication number: 20100304012
    Abstract: A coating providing high abrasion and chemical resistance composed of a barrier layer from vanadium, molybdenum, niobium, tantalum and the like, and an outer layer of diamond-like carbon. The coating is especially applicable for acoustic wave device (AWD) based sensors, and for passivating an electrode such as an electrode deposited on the AWD sensing area. The coating provides excellent mechanical and acoustical characteristics for coating acoustic wave devices allowing the sensor to operate in harsh environments.
    Type: Application
    Filed: August 12, 2010
    Publication date: December 2, 2010
    Applicant: DELAWARE CAPITAL FORMATION, INC.
    Inventors: Jeffrey C. Andle, Reichl B. Haskell, John H. Bradshaw

  • Pressure testing apparatus
    Patent number: 4366715
    Abstract: Apparatus for testing internal pressure of a pressurized container having a ball partially extending outwardly from a ball seat includes a vise for holding the container in a fixed position and a force generating transducer arranged to provide a force proportional to the internal pressure for moving an end of a lever arm against the ball and statically holding the ball in a position substantially midway between first and second extremities of the ball seat.
