  • Conventional brake pipe continuity test
    Patent number: 6626034
    Abstract: The method includes reducing pressure of a charged brake pipe to a predetermined pressure value. The brake pipe is then charged only from the head end unit. Each intermediate brake pipe monitoring and charging device sequentially reports on the network a pressure which is an increase if the brake pipe is continuous between it and the head end unit. Subsequent to receipt of a report of an increased pressure on the network from an intermediate unit, the head end unit commands that intermediate unit to participate in charging the brake pipe. The head end unit determines the brake pipe continuity from the pressure increases reported by the intermediate units.
    Type: Grant

  • Hand held dispenser for foamable compositions and dispensing system
    Patent number: 5709317
    Abstract: A hand held dispenser for dispensing foamable compositions is disclosed that is particularly useful for foam-in-place packaging systems. The hand held dispenser comprises a housing; a motor in the housing; a transmission in the housing and driven by the motor; and a valving cartridge in the housing and driven by the transmission for dispensing foamable compositions upon demand. The motor is positioned below the valving cartridge for providing a clear line of sight along the top of the housing.
