Abstract:
A system for storing an ammonia precursor including a tank configured to hold the ammonia precursor; a filler opening closed by a cap, the cap being removable for refilling the tank; and a semi-permeable membrane positioned within the cap. The semi-permeable membrane is configured to block liquid from the ammonia precursor and configured to allow air and vapors from the ammonia precursor to pass therethrough when the cap is closing the filler opening. When the cap is closing the filler opening, a pathway allowing a substantial amount of vapors to escape from the tank to the atmosphere is provided so that the total internal volume of the reservoir in liters divided by the flow rate in liters per hour through the membrane at 10 mbar is lower than 20 hours.
Abstract:
This invention relates to a container for use with an endoscope. More particularly, this invention relates to a container for storing and delivering sterile water to an endoscope. A container for storing sterile water for supply to an endoscope comprises a substantially rigid receptacle providing an internal volume for storing said water, the receptacle having opposing first and second end walls, in use said first end wall forming a base of the receptacle and said second end wall forming a top of the receptacle such that a vertical axis of the receptacle extends substantially perpendicular to the first and second end walls; a first port for connection to an air line of an endoscope; a second port for connection to a water line of an endoscope; a first fluid conduit extending between the receptacle and the first port; and a second fluid conduit extending between the receptacle and the second port, wherein, in use, the first and second ports are located in a fixed position with respect to the receptacle such that the first and second ports lie in the same vertical plane as the centre of gravity of the container when the receptacle is filled with water.
Abstract:
A coolant reservoir and associated multi-functional unit for a thermal sub-system of a fuel cell system. The coolant reservoir includes a flame arrester positioned in a gas region of the reservoir. The multi-functional unit includes a first pressure relief valve that automatically opens if the pressure within the gas region goes above a first predetermined pressure. The multi-functional unit may also include a second pressure release valve that quickly releases pressure in the coolant reservoir if the pressure within the gas region goes above a second higher predetermined pressure. The multi-functional unit also includes an air-line and a check valve for allowing ambient air to enter the gas region if the pressure within the gas region falls below ambient pressure. The multi-functional unit also includes a cooling fluid fill line having plumbing that causes the coolant reservoir to vent prior to a cooling fluid cap being removed.
Abstract:
A drop separator for the bleeding line of a fuel container, comprising a drop separator housing that is connected to a space surrounded by the filler tube of the fuel container, preferably directly to the refueling channel of the filler tube, and at least two bleeding line connections, wherein the housing is divided by at least one partition into at least two separate gas paths, wherein a first gas path is designed as a gas inlet channel and a second gas path as a gas outlet channel. The gas inlet channel is closed on the end face by a lid and communicates via a passage of a surrounding wall of the drop separator housing with the filler tube.
Abstract:
A fuel-filling aperture open-closing device provided in a filler pipe communicated with a fuel tank includes a tube member forming a pathway and connected to one end of the filler pipe, and a valve body rotatably provided inside the pathway, blocking the pathway by an urging member, and opening the pathway when rotating to an inner end side of the pathway by being pressed by a fuel-filling nozzle inserted into the pathway. The tube member includes a discharge hole communicating an outer surface with an inner surface of the tube member in a portion in which an outer surface of a lateral circumferential portion thereof faces downward, and corresponding to a portion on the outer end side in a closed position of the valve body. The valve body includes a plurality of discharge grooves extending toward the discharge hole in a portion on the outer end side.
Abstract:
The present invention provides an underground tank having a vessel assembly and a generally spaced access assembly. That is, the access assembly includes a fuel line, a withdrawal line, and a dome assembly. The fuel line and the withdrawal line have a first end disposed outside the vessel assembly and a second end disposed adjacent to or within the vessel assembly. The first end extends upwardly from the vessel assembly toward the ground surface. The dome assembly is coupled adjacent to the fuel and withdrawal line first end. As such, the vessel assembly may be buried at any depth as the fuel and withdrawal lines may have any length.
Abstract:
A delivering tap (1), for delivering liquids from a container, comprising at least one body (3) made in a single piece and integral with at least one elastic, flexible thrusting pushbutton (17) and at least one flexible sealing lip (25), and at least one valve member (5) with integrated spring inside the body (3), the body (3) comprising at least one head (11) equipped with at least one delivering beak (12) for delivering liquids, the delivering beak (12) communicating with one and only one internal chamber (13) of the body (3) into which, during the delivery of liquid, a lower space for passing liquid (L) and an upper space for passing air (A) are naturally defined.
Abstract:
A valve assembly (10) able to be mounted with a liquid container, the valve assembly comprising: a housing (20) having a passageway (60) that extends through the housing; a breather float valve (80) mounted within the housing, the breather float valve movable between an open position to allow gas to pass through the passageway and a closed position that prevents liquid from passing through the passageway; a liquid inlet (30), forming part of the housing, the liquid inlet allowing fluid to pass into the housing; and an inlet float valve (41) mounted within the housing, the inlet float valve movable between an open position that permits the flow of liquid through the liquid inlet and a closed position that prevents the flow of fluid through the liquid inlet.
Abstract:
A valve assembly includes a housing. A membrane supported by the housing such that the membrane covers a vapor passage defined by the housing. The membrane allows the passage of vapor through the membrane and prevents the passage of liquid through the membrane. A flow control feature is supported by the housing and at least partially controls flow of a vapor to the vapor passage. The flow control feature enables variable flow of vapor to the vapor passage.
