摘要： Techniques for implementing and/or operating a system that includes a pipe fitting to be secured to a pipe segment, in which the pipe fitting includes a grab ring having a grab notch and a fitting jacket to be conformally deformed around tubing of the pipe segment to facilitate securing the pipe fitting to the pipe segment. Additionally, the system includes a swage machine, which includes a grab plate having a grab tab that matingly interlocks with the grab notch on the grab ring to facilitate securing the pipe fitting to the swage machine, a die plate in which a die is loaded, and a swaging actuator secured to the die plate. The swage machine operates the swaging actuator to push the die plate over the fitting jacket of the pipe fitting to facilitate conformally deforming the fitting jacket around the tubing of the pipe segment via a forward stroke.

摘要： This invention relates to an air valve which includes a deflector positioned inside a float chamber in order to improve the flow of air through the air valve. Further, the air valve includes an upper opening leading from the float chamber and having a transverse cross-section which increases away from the float chamber in order to smooth air flow. The invention further relates to an air valve accessory whereby an air valve can be modified in order to improve air flow therethrough.

摘要： The present specification relates generally to flow management devices and specifically to an adaptive fluid flow management device for water service pipes which includes a housing, which defines a passage for fluid to flow therethrough, a rod, at least one torsion spring, at least one flap gate, and at least one aperture. The at least one flap gate being of a dimension that substantially covers an end of the housing and is configured to pivot about the rod such that, at rest, it is positioned perpendicular to an end of the housing. The at least one flap gate and a perimeter of an end of the housing define the at least one aperture, to allow fluid to flow therethrough. Also disclosed are methods of reducing a measured volume of water passing through a water meter and calibrating a fluid flow management device.

摘要： The invention described herein is that of an outdoor drain filter useful for maintaining the operability of an outdoor drain despite the accumulation of debris that would otherwise obstruct the outdoor drain, resulting in flood prevention of surrounding areas. The outdoor drain filter of the present invention is placed above and around an existing outdoor drain or may be integral with a drain cover or drain reservoir. The outdoor drain filter comprises upper and side filtration means allowing the free flow of water therethrough. The outdoor drain filter further comprises a diverter comprising at least one air vent and at least one lateral pipe that defines a maximum water level to which water will accumulate around the outdoor drain before being diverted into the drain through the diverter. The outdoor drain filter may a manufactured unit or of modular construction.

摘要： L'embout (14) définit au moins un passage d'évacuation (60) d'un gaz. Il comprend un élément d'obturation sélective (62) disposé dans le passage d'évacuation (60), propre à permettre l'évacuation de gaz à travers le passage d'évacuation (60) dans le sens allant de l'intérieur vers l'extérieur de la ligne flexible et à empêcher la circulation de fluide à travers le passage d'évacuation (60) au-delà de l'élément d'obturation sélective (62) depuis l'extérieur vers l'intérieur. Au moins un organe de fermeture bidirectionnelle (66) du passage d'évacuation (60) est disposé dans le passage d'évacuation (60) et/ou à sa sortie. L'organe de fermeture bidirectionnelle (66) est propre à passer d'une configuration fermée d'obturation du passage d'évacuation (60) à une configuration ouverte d'évacuation d'une surpression de gaz dans le passage d'évacuation (60).

摘要： A system that automatically prevents freezing of a liquid in a plumbing network includes an electrical temperature sensor, an electromechanical shut-off valve, a pump (such as an air compressor pump and a vacuum pump) and an operatively connected computer. The computer determines if the temperature detected by the electrical temperature sensor is within a predetermined range of a threshold temperature. If so, the computer actuates the shut-off valve to prevent the liquid from flowing from a liquid source to a portion of the plumbing network, and actuates the pump to discharge the liquid from the portion of the plumbing network to the liquid drain. The computer may actuate additional electromechanical valves on the plumbing network to facilitate discharge of the liquid, and on a supply line to allow the liquid to continue circulating in the supply line.
