| 20120125076 | PORTABLE METERED FLOW APPARATUS FOR CALIBRATION/BUMP TESTING - A portable metered flow apparatus for accurately providing calibration gas from a calibration gas source to a gas monitoring instrument in order to permit calibration/bump testing of the instrument comprising a regulator and a gas delivery device that includes a solenoid valve, an electronic timing circuit, means for providing power to the solenoid valve and the electronic timing circuit, a power switch for activating the electronic timing circuit, means for activating the release of calibration gas; and optionally one or more LED lights. A method for calibration/bump testing of a gas monitoring device utilizing the portable metered flow apparatus is also provided. | 05-24-2012 |
| 20110000551 | Push Button Regulator Device with Sealing Element to Facilitate Easy Connection with Other Devices - A regulator device includes a first valve member and a second valve member disposed within a housing of the device. The first valve member regulates the pressure of fluid exiting the device, and the second valve member is biased to a closed position and is opened by manipulation of an actuator. A sealing element is connected at the housing outlet and has a transverse cross-sectional dimension that decreases from an inlet of the sealing element to an outlet of the sealing element. In addition, a guard is provided that extends around a periphery of the actuator and includes a cut-out section to permit easy access to the actuator during use of the device. | 01-06-2011 |
| 20090245319 | Burner/Injector Panel Apparatus - The present invention generally relates to an apparatus and method for use in metal melting, refining and/or other processing, such as, for example, steel making in an electric arc furnace (EAF), and more particularly, to improved burner/injector panels and related methods for the introduction of various energy sources, such as, for example, chemical energy, oxygen and particulates into an EAF. | 10-01-2009 |
