  • Speed control of variable speed pump
    Patent number: 6739840
    Abstract: Method, article of manufacture and apparatus for monitoring operating characteristics of a system comprising a variable speed vacuum pump. Operating characteristics reflective of gas load on the pump are observed for behavior indicating a change in the gas load. In one embodiment, the operating characteristic is the current in a power signal being provided to the pump.
    Type: Grant

  • Variable speed pump control
    Publication number: 20040013531
    Abstract: A method and apparatus for monitoring operating characteristics and/or control signals of a system comprising a variable speed vacuum pump. Operating characteristics and/or control signals of the system may be monitored, and the pumping speed of the variable speed vacuum pump may be altered responsive to the monitored operating characteristics and/or control signals.

  • System for protecting telecommunications equipment from transient voltages
    Patent number: 6298134
    Abstract: A system that protects telecommunications equipment from AC power faults and voltage transients comprising (1) a high-energy foldback device between the current-carrying lines of a telephone system and ground; (2) a voltage clamping device between the current-carrying lines; (3) a foldback device between the current-carrying lines and ground; (4) a first overcurrent protection device connected in series with the above foldback device; and (5) a second overcurrent protection device in the lines between the high-energy foldback device and the above mentioned serially connected foldback device and first overcurrent protection device. The system may be used, for example, with standard telephone lines, PBX out-of-building lines, special service lines such as carrier, pair-gain, and high speed data, and dedicated voice-band services such as pay phones and traffic-control communication lines.
