Abstract: A fuel tank joint includes a tubular joint body and an entry restriction member. The joint body includes a support portion. The entry restriction member includes a body tube, a groove, a guide, and an engagement hook. The body tube has opposite open ends in the flow direction of fuel. The groove extends upstream from the downstream end of the body tube and is engaged with the support portion. The guide is formed in part of the body tube that includes the downstream end of the body tube and guides the groove to the support portion by contacting the support portion when the body tube is inserted into the joint body. The engagement hook is formed in a downstream end section of the body tube and engaged with the support portion, from a downstream side, in a state in which the groove is engaged with the support portion.

Abstract: A filler valve unit (1) for feeding a preset amount of filling liquid (3) into a container (6) having an outlet (4) for feeding out filling liquid and an outlet (11) for injecting gaseous fluid. The filler valve unit (1) comprises at least one stop element (14) forming a stroke limiter acting on the container (6). According to the invention, the stop element (14) is mobile and moves between at least two operating positions consisting of a first operating position wherein the stop element holds the mouth (5) of a container (6) at a preset distance from the outlet (4) and a second operating position wherein the stop element (14) holds the mouth (5) of the container (6) at a distance from the outlet (4) which is less than the preset distance.

Abstract: Hydrogen filling station, in particular, for refilling vehicle tanks with hydrogen gas, comprising a source reservoir designed to hold liquid hydrogen (LH2), a pipe for withdrawing liquid hydrogen from the source reservoir to at least one user station, an electric cryogenic pump arranged within the withdrawing pipe and an electric power supply connected to the cryogenic pump to supply the same with electricity, characterized in that the electric energy supply comprises at least one fuel cell.

Abstract: A sprayer that delivers a pattern of paint that can be obtained from a container. The sprayer generally includes a sprayer body that emits the pattern with the paint. The sprayer also includes a reservoir including a cavity that when connected thereto provides the paint to the sprayer body. The reservoir includes a cylinder and a piston assembly manually movable in the cylinder to draw the paint into the cylinder when the reservoir is connected to the container.

Abstract: A manually operated wine vacuum device that evacuates air from a partially filled bottle of wine or other oxygen-sensitive liquid prior to storage includes: (a) a body that defines a chamber; (b) a one-way de-aeration valve, and (c) a stopper that is adapted to be inserted into the interior of the bottle through the bottle's opening such that the interior of the bottle becomes in communication with the de-aeration valve which is configured so that gas flows into the chamber when the pressure in the chamber is lower than that of the interior of the bottle but gas does not flow into the interior of the bottle when the chamber is at a higher pressure. An open bottle abuts a collar formed in a recess region of the body as the bottle is coupled to the stopper and a piston slidably disposed within the chamber removes gas from the interior of the chamber when the piston is activated.

Abstract: The fueling device has a fueling pipe adapted to supply fuel pumped from the inlet opening the fuel tank. A grating member is situated inside the fueling pipe. The grating member includes an annular body positioned substantially concentrically with the fuel passage; and a support body adapted to support the annular body on the inside wall of the flow passage. Gaps present between the inside wall of the passage-defining member and the annular body and the support body constitute part of the fuel passage.

Abstract: An apparatus for internally venting a product tank in a packaging machine is set forth. The apparatus includes a filling tube having a first end extending from a first opening of the product tank. The apparatus further includes an air collection mechanism having a filling tube opening adapted to receive a second end of the filling tube. The air collection mechanism extends below the second end of the filling tube. A vent pipe is connected to a second opening of the product tank and to a vent pipe opening in the air collection mechanism. The filling tube and the vent pipe are separately connected to both the product tank and the air collection mechanism. Air pressure, arising from operating the packaging machine, directs air from the air collection mechanism through the vent pipe and into the product tank. Such air proceeds through the vent pipe and replaces product in the product tank as the product is dispersed into the carton during filling.

Abstract: A receptacle includes a receiving chamber into which an injection fluid is to be injected. An injection unit includes a syringe having a needle adapted to pierce a diaphragm of the receptacle. The injection unit has a second needle [(28)] that may be advanced through a further diaphragm into a return chamber of the receptacle. The second needle is secured to a sliding pipe coupled to the syringe via a coupling means. Both needles are advanced simultaneously into the receptacle. Then, the syringe is ejected by moving the syringe plunger. The liquid volume displaced from the return chamber reaches the rear barrel chamber via the sliding pipe, the volume of the rear barrel chamber increasing by the amount in which the injection fluid has been ejected, subtracting the volume of the plunger rod. The exchange of liquid is supported by the suction effect of the partial vacuum generated by the lowering of the syringe plunger. The fluid of the injection device is sealed tight against the environment.

Abstract: a system and method are provided for transferring a liquid cryogen from a supply tank to a receiver tank by pressurizing the supply tank with cold vapor from the receiver tank. This method minimizes heat added to the transferred liquid and minimizes the temperature of the vapor returned to the supply tank, making it particularly useful for optimizing the transfer of liquid cryogens such as helium, hydrogen, nitrogen and oxygen which vaporize well below ambient temperatures. A cold vapor pump is provided which is insulated from ambient temperatures for pumping the cryogen vapor from the receiver tank to the supply tank with a minimum of heat input.
