  • Patent number: 7984934
    Abstract: Copper purge fittings for brazing components of a special gas delivery line together are provided. An orifice is located on the top or end portion of each fitting to create a continuous flow of inert purging gas through the delivery line under construction while brazing. Each fitting will reach temperatures exceeding 1500 degrees. By having a continuous flow of inert gas while brazing, the protection of the interior portion of the system remains intact. Without a purge in place, the intense heat would create a rapid immediate buildup of carbon and other contaminates. Brazing is only commenced after the elimination of harmful oxygen and proper flow of purging gas is measured. The purging gas pressure is lowered if it becomes high enough to potentially cause separation of tubular sections from the purge fittings and is raised if a low flow rate is detected indicating potential insufficient flow of purging gas.

    Abstract: A clampless coupling which attaches a hose to a nipple without need of a clamp at the end of the hose to ensure sealing, including a connector and a nipple of a fluid system component. The connector is sealingly pre-connected at one end with a hose; the opposite end is in the form of a sleeve. The sleeve features a notch at its forward end, a boss on a resilient lock arm, and an O-ring seal. The nipple has a pocket depressionally formed on its outside nipple surface and an alignment tab. In operation, a user slides the sleeve over the nipple by pressing the connector toward the near end of the nipple. As the sleeve slides over the nipple, the tab is received by the notch to align the connector with the nipple, the boss drops abuttably into the pocket, and the O-ring seal sealingly compresses between the nipple and the connector. A seal assurance feature reveals improper connection when a pressure test is undertaken.

  • Patent number: 6298881
    Abstract: A modular fluid handling assembly includes a plurality of fluid handling units. Each fluid handling unit includes a fluid passage and associated port, a vacuum passage and associated port, a vacuum pressure source, and a containment seal. The fluid passage ports and vacuum passage ports of adjacent fluid handling units respectively communicate. The containment seal is disposed between adjacent fluid handling units and surrounds the communicating fluid passage ports and vacuum passage ports. The vacuum pressure source is in continuous communication with the vacuum passages of the fluid handling units, generates an urging force which aids in sealing adjacent fluid handling units together, and draws off any fluid that may leak from a fluid passage port. A sensor can be tapped into the vacuum line to sense whether any fluid has leaked from a fluid passage port.

  • Patent number: 6047994
    Abstract: A blocking arrangement serves for securing prevention of a spear (1) being unscrewed from a corresponding neck ring (3) in a container for a liquid, for example, beer, being under pressure by a drive gas in the container. The blocking arrangement consists of a split spring ring (8) which is placed in a groove (5) constructed in the corresponding neck ring (3). This groove is so deep that the spring ring is allowed to be squeezed radially into the groove. The expansion for the spring ring radially outwardly is limited, however, by in inwardly turning cylinder face (22) on the spear (1). Furthermore, the spear has an upwardly turning blocking face (12) which adjoins the cylinder face (22). When dismounting of the spear is attempted, its blocking face (12) adjoins the spring ring (8) which is retained axially by the downwardly turning upper side (16) of the groove.
