Patent number: 7487796Abstract: A breakaway coupling for a fuel supply hose includes a male valve body interfitting with a female valve body for defining a fuel passage, and the valve bodies enclose axially movable spring biased poppet valve members. The valve bodies are connected by a permanent magnetic coupling system which provides for moving the valve bodies from a connected position to a disconnected position in response to a substantial axial tension force on the valve bodies. In one embodiment, the coupling system includes an annular strike member surrounding the fuel passage and a mating annular magnet member supporting a plurality of circumferentially spaced permanent magnets of rare earth materials. In another embodiment, the valve bodies define a vapor return passage with a poppet valve member and disposed either radially outboard or inboard of the fuel passage. The magnetic coupling system also simplifies reconnecting the valve bodies.Type: GrantFiled: July 31, 2007Date of Patent: February 10, 2009Assignee: Catlow, Inc.Inventors: David L. Imler, Paul D.

Patent number: 7476368Abstract: A system for microbially deactivating items. The system includes a circulation system for circulating a microbial decontamination fluid through a deactivation chamber that forms a part of the circulation system. A container for holding items to be deactivated is provided. The container has a sealable cavity in which the items to be deactivated may be placed, and at least one valve element that is movable between an open and a closed position to regulate fluid flow into the cavity. An actuator in the deactivation chamber is operable to move the valve element to an open position when the container is disposed within the deactivation chamber, wherein the cavity within the container is in fluid communication with the circulation system when the valve element is in the open position.Type: GrantFiled: August 1, 2003Date of Patent: January 13, 2009Assignee: American Sterilizer CompanyInventors: Donald A. Sargent, Christopher A. Jethrow, Jude A. Kral, Karl F. Ludwig, Victor Selig

Patent number: 7296782Abstract: A valve comprising an inlet housing, an outlet housing, an elastomeric valve element having a generally dome-shaped configuration with a central integral stem positioned substantially concentrically therewith, the inlet housing and outlet housing being fastened together at a joint with the elastomeric valve element positioned therein and the valve element including a plurality of longitudinal ribs formed along an outer annular periphery of a lower end of the dome-shaped configuration that define flow channels that allow fluid flow from across an upper surface of the dome-shaped configuration through the flow channels.Type: GrantFiled: September 29, 2005Date of Patent: November 20, 2007Assignee: Halkey-Roberts CorporationInventors: Jon R. Enerson, Gregory S. Jordan, Pavel T. Miller

Patent number: 7182108Abstract: An apparatus and method is provided for automatically venting a fluid from at least a portion of a pressurized system. An interconnection between two devices in the system contains an automatic bleed valve configured to automatically seal a vent hole when the two devices are coupled together and to automatically unseal the vent hole before the two devices are separated. In an embodiment, an adapter includes a ring that both screws a connector onto a device and seals a vent hole. A pin is pushed into the vent hole as the connector is screwed to the device. To remove the adapter from the device, the ring is turned to both unseal the vent hole and to unscrew the connector from the device. Turning the ring releases the pin before the connector is unscrewed.Type: GrantFiled: June 28, 2004Date of Patent: February 27, 2007Assignee: Submersible Systems, Inc.Inventor: Larry H. Williamson

Patent number: 7077176Abstract: A vial has a body defining a chamber for receiving a substance therein; and a valve assembly coupled in fluid communication with the chamber and defining (i) an open position permitting at least one of (a) passage of the substance through the valve assembly and into the chamber for storing the substance in the chamber, and (b) passage of the substance out of the chamber for dispensing the substance therefrom; and (ii) a closed position forming a fluid-tight seal between the chamber and exterior of the container. A filling member engages a flexible valve member of the valve assembly to move the valve member between the closed and open positions to fill and seal the vial, respectively. A syringe is connectable to the vial.Type: GrantFiled: April 28, 2004Date of Patent: July 18, 2006Assignee: Medical Instill Technologies, Inc.Inventor: Daniel Py

Patent number: 6981612Abstract: A pin valve assembly includes a spring biasing a piston against a seal to seal an opening of a gas cylinder. The spring compresses a length determined by a distance between the insert and the plunger. The insert is pressed into an opening opposite the plunger and held in place by at least one barb extending inward from an inner diameter of a body of the insert. The insert includes an opening to allow communication of gas pressure to a rear portion of the piston. The inner diameter of the pin valve assembly includes at least one barb to secure and prevent removal of the insert.Type: GrantFiled: December 19, 2003Date of Patent: January 3, 2006Assignee: Gas Cylinder TechnologiesInventors: Thomas S. Siimes, Timo Siimes
