Abstract: 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.

Abstract: 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.

Abstract: A quick connect fuel hose connector for connecting an LP fuel hose to a threaded inlet fitting on a vehicle or appliance fuel tank comprises an annular body having an inlet for fuel at an inner end and an outlet for fuel at a recessed opening in an outer end. Latch members pivotally mounted in slots on opposite sides of the body engage and latch the connector to the fuel tank inlet fitting when the connector is fitted over the inlet fitting. A lost motion spring seal maintains a tight seal between the connector and the inlet fitting. A replaceable nose seal on an outlet valve in the connector provides an improved sealing connection between the connector outlet valve and the fuel tank inlet valve.

Abstract: An improved fuel line connector for connecting a fuel line connection valve to a fuel cylinder outlet valve includes an improved, replaceable tip seal mounted on the tip or nose of the connector valve. The tip seal provides an additional, effective face seal between the connector body and the cylinder outlet valve. The tip seal, being on the fuel line connector, can be maintained and replaced by the party using the vehicle or filling the fuel cylinder.

Abstract: 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.

Abstract: A gas convenience outlet for connecting an outdoor grill or other gas fired appliance to a home gas supply or other fixed position source of natural gas or liquid petroleum gas comprises 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 a supply of fuel gas and one or more outlets. A primary manual shutoff valve located in the interior is operatively connected with the manifold outlet. The outlet includes an outlet connector extending outside the interior. 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 adaptors and without loss of performance.

Abstract: An adjustable floating seal piston type pressure regulator valve of the type wherein a spring biased piston engages a floating seal in a regulator body valve chamber to open and close a valve seat outlet in the valve chamber. The valve seat comprises a separate member from the regulator body and is adjustably movable in the valve chamber toward and away from the piston, such that movement of the valve seat toward the piston serves to lower a regulated outlet pressure and movement of the valve seat away from the piston serves to increase the regulated outlet pressure. The valve seat member is moved by an adjustment screw that is externally accessible by an adjustment tool. A tubular expansion chamber surrounds the regulator body and provides an enlarged expansion chamber that reduces valve recycle time. Convolutions or ribs in the expansion chamber housing enhance heat through transfer to the valve gases.

Abstract: An appliance end fitting for connecting a gas operated appliance to a pressurized gas cylinder includes a simplified interior valve that acts as both a thermal valve and an excess flow control valve. The end fitting has an elongated body formed in two telescoping sections, an inner section, and an outer section. An interior opening extends through both sections and includes an enlarged center portion. A floating valve member in the center portion is movable toward a valve seat at an outer end of the center section. A spring urges the valve member away from the valve seat but excessive gas flow moves the valve member toward the valve seat and restricts the valve. The two sections of the body are held in an extended axial position by a heat activated material, such as fusible solder, where the nipple opens the cylinder shutoff valve when the body is connected to the cylinder outlet.

Abstract: A piston pressure regulator has a body, a corresponding piston, and a floating seal. The body includes an interior piston cavity, a low pressure port connected with the piston cavity, and a high pressure port connected with the piston cavity. Further, the piston cavity has a length. The corresponding piston is located in the piston cavity and cooperates with the piston cavity to define low pressure and high pressure portions of the piston cavity and low pressure and high pressure sides of the piston. The piston also slides along the piston cavity length, between the low and high pressure ports. The seal is a wafer member that is interposed between the piston and the high pressure port. The seal is separate from each of the piston and the high pressure port to "float" between the piston and the high pressure port. Seals of different thicknesses may be substituted to adjust the operating pressure.
