Abstract: 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, a device for providing power to the solenoid valve and the electronic timing circuit, a power switch for activating the electronic timing circuit, a device 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.

Abstract: The present invention generally relates to apparatuses and methods 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 panels and related methods for the introduction of various energy sources, such as, for example, chemical energy and particulates.

Abstract: 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.

Abstract: A non-refillable valve device includes a housing with an axially extending internal cavity, where the internal cavity includes a chamber extending to an end of the housing. The housing is securable to a container to facilitate fluid communication between the container and the housing chamber. A plug member is secured within the housing chamber to provide a fluid flow passage between the container and the housing chamber when the housing is secured to the container, and an elastic sealing member is also disposed within the chamber. The sealing member is displaceable from a first position to a second position within the chamber, where the sealing member in the first position permits fluid flowing into the valve device to flow through the fluid flow passage and into the container, and the sealing member in the second position substantially prevents fluid flow through the fluid flow passage and into the container.
