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 mixing apparatus, puncturing mechanism, and cartridge are disclosed. The mixing apparatus has a housing and a drawer with a recess. Corresponding cartridges may be inserted into the drawer and slid into the housing to facilitate mixing a liquid with contents of the cartridge. The liquid may originate from a reservoir in the mixing apparatus or a direct line. Also inside the housing of the mixing apparatus is the puncturing mechanism. The puncturing mechanism has a nozzle configured to puncture a lid of a cartridge and inject liquid to mix with the contents of the cartridge. The puncturing mechanism is further configured to drive an internal puncturing unit inside of the cartridge through a lower portion of the cartridge to allow liquid from the nozzle and contents of the cartridge to be dispensed into a receptacle.

The Drain Free Applicator is an invention that prevents the buildup of mold and algae in pipes that drain condensation produced by evaporation coils within an air conditioning unit. This invention does so by holding treating tablets that are dissolved by the draining condensation and swept into the draining pipelines. This invention prevents the drain pan from filling up and overflowing with subsequent water damage to floors and ceilings. In newer units, it prevents triggering the water level sensor and shutting down the air conditioning unit.

An AC drain line, anti-contaminant device includes a housing unit comprising a volume to receive an anti-contaminant agent, a housing inlet coupled to a drain line to allow a flow of a drained fluid to enter the housing unit, and a housing outlet to allow the drained fluid to exit the housing unit upon conditioning by the anti-contaminant agent. The drain line couples to and extends from a drip pan of an AC system, and subsequently couples to the device. The anti-contaminant agent comprises anti-algae, anti-mold, or other anti-deleterious material agent comprising a high concentration of [OH.sup.] dissociative ions wherein the pOH is less than or about 5. The housing may include an internal support to space the anti-contaminant agent apart from the bottom. The anti-contaminant agent may comprise a solid form for placement in the housing, or as part of a removable and replaceable cartridge assembly for the device.

A method and apparatus for obtaining a product chemistry from a slid block of caustic material is provided. The product is housed within a capsule which is positioned inside a turbulent flow dispenser, which utilizes fluid to erode the block and produce a concentrated solution. The fluid characteristics can be adjusted in the field to achieve a predetermined concentrate level of the solution. The capsule provides a safe and convenient means for handling, storing and shipping the caustic block without exposing the operator or handler to the hazardous material. The capsule includes nested components which can be rotated between a closed or sealed position and an open use position.

A system, a cartridge and a dispensing valve for eliminating a drift or sag in BCDMH output from an inline dispensing valve containing a dispensing cartridge mountable within the inline dispensing valve with the dispensing cartridge containing a batch of water erodible cluster inhibiting BCDMH particles to provide a linear output flow of BCDMH which is responsive to flow of water though a cartridge in the dispensing valve and a method of obtaining a linear output in a dispensing system by increasing the size of particles in a dispensing cartridge in the system.

A chemical feeder includes a housing having a housing chamber, a sieve plate within the housing chamber, and a cartridge on an upper surface of the sieve plate. The cartridge includes a tubular member with a sidewall outer surface and a plurality of partitions extending from the sidewall outer surface to define a plurality of pockets, at least one of which contains a solid chemical material. The sieve plate includes a plurality of sieve plate inlet apertures, at least a portion of which are in fluid communication with at least one of the plurality of pockets. During operation, a feed liquid passes up through at least a portion of the sieve inlet plate apertures and into at least one pocket where it contacts a solid chemical material, so as to form a treated liquid that includes dissolved chemical material, at least a portion of which is removed through an outlet.

A mixing apparatus for reconstituting a powdered cell culture media. The apparatus includes at least one fluid chamber, an influent port at a lower portion of the fluid chamber. The apparatus further includes a geometric fluid flow aid positioned in the fluid chamber and an effluent port at the top of the fluid chamber. A powdered cell culture media is provided in the fluid to be mixed with a fluid provided by the influent port. The effluent port is configured to allow reconstituted media to exit the fluid chamber.

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.

In some embodiments, a water straining and chemical additive device may include a filter body having a wall inflow surface, a central aperture, and a peripheral aperture. A return water tube having a tube outflow surface and a tube inflow surface may be coupled to the filter body. An inflow conduit may be in fluid communication with the peripheral aperture, and the inflow conduit may be formed by the wall inflow surface and the tube inflow surface. An inflow filter screen may be coupled to the peripheral aperture. A filter cap forming a primary cavity in fluid communication with the central aperture and the peripheral aperture may be coupled to the filter body. An outflow filter screen may be coupled to the central aperture. An outflow conduit may be in fluid communication with the central aperture, and the outflow conduit may be formed by the tube outflow surface.
