A method for quick filling a vehicle hydrogen storage vessel with hydrogen, the key component of which is an algorithm used to control the fill process, which interacts with the hydrogen dispensing apparatus to determine the vehicle hydrogen storage vessel capacity.

An apparatus for rapidly filling a hydrogen tank with a hydrogen gas comprises a hydrogen source; a hydrogen tank; a passage which connects the hydrogen source and said hydrogen tank; and a mechanism for varying the hydrogen-filling rate. The mechanism for varying the hydrogen-filling rate changes the hydrogen-filling rate depending upon the pressure within said hydrogen tank. The apparatus can suppress heat generation at the initial filling stage where the temperature is easily increased. Also, even if it takes longer time for increasing the pressure within the hydrogen tank at the initial filling state, the delayed time can be caught up and, the apparatus and the process of the present invention can totally attain a rapidly filling with hydrogen.

An apparatus for metering a urea or a urea-water solution for delivery to a catalytic converter assembly for removing nitrogen oxides from the exhaust gases of a Diesel engine, includes a housing block supporting function components communicating via a line, formed by recesses in the housing block, for transporting the reducing agent, and the walls of the line are formed by the housing block. This apparatus assures a simple line layout for reducing agent with a minimum number of sealing points that is accordingly appropriate for large-scale mass production.

An automatic vaccinator of eggs, consisting of a system for applying vaccine with a vaccine chamber in which vaccine bags are hung and with an air bag that, when expanded, forces the vaccine from the bags and through tubing to a distribution manifold and the injectors, so that the vaccine is delivered to the eggs, is disclosed. A pressure sensor is installed in the distribution manifold and connected to a regulator, measuring the pressure in the distribution manifold at the point farthest from the vaccine chamber and controlling the pressure in the air bag to maintain a uniform quantity of vaccine being injected into the eggs and turning off the vaccinator if the pressure falls below a critical level, signaling that the vaccine bags are empty. The mechanical unit includes a system to support, align and secure the injectors over the egg tray, composed of two plates that work independently, a support plate and an alignment plate.

A fiber-reinforced composite structure has two molded outer polymeric layers spaced apart from each other and defining a cavity therebetween. Each molded outer polymeric layer defines a sealing surface extending about a periphery of the respective layer, and the opposing sealing surfaces cooperate to define a hermetic seal extending about a periphery of the cavity. One or more multi-directional fiber reinforcement layers are adhesively attached in a discontinuous manner to each outer polymeric layer, and define a first region of the cavity extending between each respective outer polymeric layer and adjacent fiber reinforcement layer, and a second region of the cavity extending between the fiber reinforcement layers. A core is located between the two outer polymeric layers, and is made of a resinous core material capable of exhibiting a foamed character and a resinous character. The resinous core material has a blowing agent activatable upon exposure to a predetermined vacuum pressure within the cavity to convert the core material within the second region of the cavity from a resinous character to a foamed character and thereby fill the second region of the cavity with the foamed core material. Each multi-directional fiber reinforcement layer is impregnated with the core material exhibiting a relatively dense, resinous character, and each first region of the cavity is substantially filled with the core material exhibiting a resinous character to fixedly secure the multi-directional fiber reinforcement layers to the outer polymeric layers. A structural insert, such as a rigid plate adapted to receive fasteners, is embedded within the core material for attaching other devices or structures thereto.

An improved valve assembly for use in a pressurized dispenser is disclosed. The disclosed valve assembly may include a valve housing and a blocking member operatively associated with the valve housing, wherein the wall of the valve housing includes at least one transverse primary opening and at least one transverse secondary opening thereon. The blocking member is slidable from a filling position, in which fluid communication between the interior and exterior of the valve housing is established through both primary and secondary openings, to a dispensing position, in which fluid communication between the interior and exterior of the valve housing is established only through the primary opening and not through the secondary opening. The blocking member may include a slidable sleeve, a slidable piston plate, or a combination of both. In operation, the disclosed valve member may provide an increased flow rate during product and / or propellant filling while retaining a regular flow rate during dispensing.
