A method and apparatus for obtaining a product chemistry from a product and a fluid is provided. A product is housed within a dispenser. A fluid is introduced through a manifold diffuse member having a plurality of ports. A cover is positioned adjacent the manifold diffuse member and includes a plurality of ports. The cover is able to be adjusted, for example, by rotating the cover, to align and un-align the manifold diffuse ports and the cover ports. This adjustment controls the flow characteristics of the fluid through the manifold diffuse member and cover to control the characteristics of the fluid in contact with the product. The adjustment of the cover to control the flow will provide a generally consistent concentration and erosion rate based upon known relationships between a characteristic of the fluid and the flow of the fluid in relation to the product.

An inline dispersal valve that can be used with or without a base. One embodiment includes a rotatable member that is rotatable from a fluid stream obstructing condition to an out-of-the-way condition to prevent fluid diversion into the dispersal valve. Another embodiment includes a lever handle for quickly setting the amount of fluid being diverted into the inline dispersal valve. Another embodiment includes an indicator that can be viewed from a position above the inline dispersal valve. Another embodiment includes a cap that can be secured or removed without the aid of tools. Another embodiment includes a clip that allows one to disassemble the inline dispersal valve for servicing. Another embodiment includes a dispensing valve that can be reversed and still properly divert fluid into a dispersant chamber. Another embodiment includes an inline dispersal valve with a bleed valve positioned to allow one to bring the air volume in the dispersant chamber to the proper level.

A water discharge dechlorinator unit includes a body having a first end adapted to be removably coupled to a water hydrant, such as a fire hydrant. The body defines a water passageway between an inlet and an outlet thereof. A chamber is in fluid communication with the water passageway and configured for reception of dechlorinating material therein, such as chlorine neutralizing tablets, whereby water from the fire hydrant passes from the water passageway and over the dechlorinating material in the chamber so as to neutralize chlorine in the water before it is discharged from the unit.

According to one embodiment, a liquid crystal display device includes an array substrate, a counter-substrate, a negative liquid crystal layer including liquid crystal molecules, a retardation film attached to a surface of the array substrate, a first polarizer attached to the retardation film and having a first absorption axis, a second polarizer attached to a surface of the counter-substrate, and having a second absorption axis which is parallel to a direction of initial alignment of the liquid crystal molecules and perpendicular to the first absorption axis, a cover member located opposite to the second polarizer, and ultraviolet curing resin which bonds the second polarizer and the cover member to each other.

A low flow apparatus for creating a solution in water of a solid chemical is provided. Also provided is a cartridge containing a solid chemical which may be placed into the apparatus. Further provided is a method of using the apparatus to create a chemical solution form a solid chemical.

A dispensing system for delivery of a dispersant from a canister containing an erodible but cakeable water dispersant wherein the cakeable water dispersant in a one piece caked condition falls to a bottom of a divergent walled canister so the water flowing through a bottom portion of the canister continues to maintain erodible contact with the dispersant as the water disperant is consumed.

A fluid injection system includes a container and fluid injection device. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and has a first end and a second end defining a ramped surface therebetween. The shroud redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives product from the container. The first end of the shroud includes a step defining a notch in fluid communication with the diverter port. The second end defines a recess in fluid communication with the injection port.

A fluid injection system includes a container, fluid injection device and a fertigation basket. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives an injection tube. The fertigation basket holds dry product which is dissolved into the container to be drawn out of outlet end via the injection tube.

A method of reconstituting a powdered cell culture media includes providing a mixing apparatus and providing a powdered cell culture media to the fluid chamber of the mixing apparatus, prior to introducing fluid to the chamber. The method further includes introducing fluid to the chamber through an influent port, wherein the influent port is tangentially oriented relative to an inner wall of the fluid chamber to thereby cause the fluid to follow the wall of the fluid chamber in a circular motion, creating a vortex flow in the fluid chamber by introducing fluid at a sufficient flow rate, and enhancing the vortex flow with a geometric fluid flow aid by further channeling the water around the wall of the fluid chamber, around the geometric flow aid. The method further includes continuing to introduce fluid to the chamber and collecting reconstituted fluid that exits the chamber through the effluent port.

A method and apparatus for obtaining a solution from a solid product in contact with a liquid is provided. A solid product is housed within a dispenser. A liquid is introduced into contact with the solid product. The solution formed between the solid product and the liquid is collected, and a makeup liquid can be added thereto to further dilute or control the concentration of the formed solution. The amount of makeup liquid added to the solution can be controlled based on the temperature of the liquid to provide an automatic, continuously variable amount of liquid added to the solution. In addition, a method of providing a pressure independent control of the makeup liquid is also provided.
