System And Method For Pump Control And Fault Detection
US Patent:
6092992, Jul 25, 2000
Filed:
Oct 24, 1996
Appl. No.:
8/736466
Inventors:
Gregory G. Imblum - Monroeville PA
Charles H. Etheridge - Pittsburgh PA
William R. Frank - Pittsburgh PA
Charles H. Etheridge - Pittsburgh PA
William R. Frank - Pittsburgh PA
International Classification:
F04B 4900
US Classification:
417 42
Abstract:
The present invention provides a system and a method for controlling and detecting faults in a pump system for use in a gas detection device. The system comprises a power source and a switch in operative or electrical connection with the power source. The system further comprises a pump motor in operative connection with the switch such that the pump motor receives energy from the power source when the switch in a first state, and the pump motor does not receive energy from the power source when the switch in a second state. The system preferably also comprises regeneration circuitry in operative connection with the pump motor. The regeneration circuitry operates to redirect energy produced from momentum of the pump motor while the switch is in the second state back to the pump motor. Transmitting circuitry is preferably provided to transmit a motor signal proportional to the speed of the pump motor during the second state of the switch. Preferably, the switch is modulated between the first state and the second state using a processing or control unit such as a microprocessor.
Devices, Systems And Methods For Testing Of Gas Detectors
US Patent:
7530255, May 12, 2009
Filed:
Jun 30, 2005
Appl. No.:
11/171861
Inventors:
William R. Frank - Pittsburgh PA, US
Daniel E. Bruce - Murrysville PA, US
Jon K. Haverstick - Butler PA, US

Assignee:
Mine Safety Appliances Company - Pittsburgh PA
International Classification:
G01N 37/00
US Classification:
73 103, 73 106
Abstract:
A testing module for use with a gas detector, includes a plurality of gas inlets and outlets, each outlet being in fluid connection with one of the inlets. Each of the outlets is adapted to mate with and form a fluid connection with one of the inlets of a second like testing module. Gases can then flow from the outlets of the testing module into the inlets of the second like testing module. A gas container module for use with a gas container, includes a plurality of gas inlets and outlets, each inlet being in fluid connection with one of the outlets. Each of the inlets is adapted to mate with and form a fluid connection with one of a the outlets on a second like gas container module. Gases can then flow from the outlets of the second like gas container module into the inlets of the gas container module.
