20090250118 | SELF-CLEANING LOW EMISSION BLEEDER VALVE TYPE LIQUID LEVEL GAUGE - A self-cleaning bleeder valve comprises an annular housing that is mounted in an opening in a pressure vessel, and a valve member that screws into the housing for movement toward and away from an orifice opening in the housing. The valve member includes a gasket seal and orifice drill at an inner end of the valve member. The orifice is positioned such that when the valve member is screwed into the annular housing, the drill extends through the orifice, automatically cleaning the orifice while restricting the rate of gas flow out of the orifice to the space between the drill and the orifice. | 10-08-2009 |
20100078084 | VALVE ASSEMBLY - A valve assembly includes a housing having a first chamber, a second chamber, and a valve seat disposed therebetween. A valve head disposed in the housing and is moveable between an open position and a closed position. The valve head defines a bore extending along an axis from the first chamber to the second chamber when the valve head is in the closed position. A valve stem is disposed in the bore and is coupled to the valve head in the bore for moving the valve head between the open and closed positions. The valve assembly allows for selective fluid communication between the first and second chambers to alleviate pressure differences between the first and second chambers. In one embodiment, the valve stem moves in the bore between a sealed position and an unsealed position. In another embodiment, a check valve is disposed in the bore. | 04-01-2010 |
20100252349 | NOZZLE ACTUATED SYSTEM FOR DISABLING A VEHICLE - A system for disabling a vehicle carrying a substance in a storage tank includes a holster defining a cavity for receiving a nozzle in fluidic connection to the storage tank when not in use. The holster includes a main body and a bracket. The bracket is affixable to the vehicle and engagable with the main body at a plurality of positions along the main body. The system further includes a sensor for sensing whether the nozzle is received in the holster. The sensor is also in communication with at least one drive element of the vehicle to disable the at least one drive element when the nozzle is not received within the holster. | 10-07-2010 |
20100252352 | SYSTEM AND METHOD FOR DISABLING A VEHICLE - A system for disabling a vehicle carrying a storage tank includes a coupler component supported by the vehicle for receiving a connection from a delivery line. A cap is attachable to an end of the coupler component for preventing connection of the delivery line when the cap is attached. A proximity sensor is disposed outside of the coupler component and senses whether the cap is attached without making contact with the cap. A switch is in electrically connected to the sensor and disables at least one drive element of the vehicle, e.g., the transmission, when the cap is not attached to the coupler component. | 10-07-2010 |
20100327575 | QUICK FILL FLUID CONNECTOR - A fluid connector having a longitudinal axis and selective open and closed conditions, the connector only in its closed condition adapted to threadedly engage a mating fluid fitting. The fluid connector includes an elongate conduit member extending along the longitudinal axis, an annular collar disposed about and having axial movement relative to the conduit member between the connector open and closed conditions, and a plurality of split nut members circumferentially distributed about the conduit member and having axial movement relative to the collar between the connector open and closed conditions. The plurality of split nut members and the collar are jointly rotatably about the longitudinal axis, and each split nut member has a distal end defining a threaded nut segment. The split nut member distal ends in the connector closed condition are constrained by the collar against radially separating movement relative to the longitudinal axis and cooperatively define a nut configured to threadedly engage a mating fluid fitting. The split nut member distal ends in the connector open condition have an expanded configuration in which, relative to the connector closed condition, they are radially separated from the longitudinal axis and not cooperatively positioned to threadedly engage a mating fluid fitting. | 12-30-2010 |
20110308633 | GAS CONVENIENCE OUTLET - A gas convenience outlet is provided for connecting an outdoor grill or other outdoor gas fired appliance to a home gas supply or other fixed position source of fuel gas, such as natural gas or liquid petroleum gas. The outlet includes a case having an open interior and an openable cover with a manifold mounted in the interior. The manifold has an inlet operatively connected with the supply of fuel gas and has one or more outlets. A primary manual shutoff valve located in the interior of the case is operatively connected with the manifold outlet. The outlet includes an outlet connector extending outside the case. The connector has a standardized fitting that releasably couples in gas tight engagement with one or more gas fired appliances by means of standardized appliance connectors, without the need for adaptors and without a loss of performance due to restriction of the gas supply. | 12-22-2011 |
20140137969 | VALVE ASSEMBLY - A valve assembly includes a housing having a first chamber, a second chamber, and a valve seat disposed therebetween. A valve head disposed in the housing and is moveable between an open position and a closed position. The valve head defines a bore extending along an axis from the first chamber to the second chamber when the valve head is in the closed position. A valve stem is disposed in the bore and is coupled to the valve head in the bore for moving the valve head between the open and closed positions. The valve assembly allows for selective fluid communication between the first and second chambers to alleviate pressure differences between the first and second chambers. In one embodiment, the valve stem moves in the bore between a sealed position and an unsealed position. In another embodiment, a check valve is disposed in the bore. | 05-22-2014 |
20140261787 | PRESSURE REGULATOR - A pressure regulator includes a housing having an upper housing portion and a lower housing portion, the lower housing portion defining an annular recess and the upper housing portion having a bottom surface, an annular protrusion extending from the bottom surface, a diaphragm disposed between the upper housing portion and the lower housing portion, the diaphragm including an outer lip having a first thickness, a flexible connecting section connected to the outer lip and having a second thickness smaller than the first thickness, and an annular inner section connected to the flexible connecting section, the outer lip having a bottom surface disposed in the annular recess and a top surface, and the protrusion being pressed into the top surface so that the outer lip seals between the upper housing portion and the lower housing portion. | 09-18-2014 |
