The apparatus includes a cover assembly unit including a mounting rack with a plurality of level indicators, a measuring vessel, for storing a liquid for dispensing, including an opening at top to be covered with the cover assembly unit, and an overflow port on a sidewall to drain an excess amount of the liquid so that a liquid surface in the measuring vessel is defined; and a dip tube attached to the mounting rack having an intake opening to remove a specific amount of the liquid from the measuring vessel, an exit end to lead the amount of the liquid to a mixing container, wherein the specific amount of the liquid is determined from the level indicators.

Abstract: Techniques for mixing liquids in a specific ratio at synchronized flows are disclosed. According to one aspect of the present invention a dispensing system comprises a plurality of tanks, each of the tanks includes an overflow outlet to limit a liquid therein to a certain measurement, and an array of volumetric outlets spaced apart and vertically arranged. The corresponding overflow outlet and the volumetric outlets of the tanks are located at the same height. The dispensing system further comprises a dispensing assembly including a manifold coupled to the volume outlets of the tanks via respective pipes, and further a flow-regulating device in at least one but not all of the pipes to control a flow of the liquid coming downwards from each of the tanks through one of the volumetric outlets thereof.

Abstract: Techniques for dispensing a type of liquid in a specific amount or at a constant flow rate are disclosed. According to one aspect of the present invention, a height difference between an inlet and an outlet is maintained by an adjustable tubing assembly. An overflow assembly is provided to divert any overflow of the liquid from entering a reservoir and keep a specific level of the liquid. A valve is provided to the inlet and can be turned off when a sensor detects that there is an overflow of the liquid in the overflow assembly.

Abstract: A method and system of near saturation gas humidification by mixing a steam and a gas flow is disclosed. The steam is generated with a heating device at a controlled rate from a liquid contained in a vessel near the point of use of the humidified gas. The controlled rate results from a feedback loop that controllably heats the liquid while measuring the steam temperature and maintaining it around a set point. The humidification delivery rate is adjustable by adjusting the temperature set point and/or the gas pressure. Undesirable components from the humidified gas are removed with an in-line filter after its point of generation. Condensation from the humidified gas before its point of use is removed with a drain pipe in combination with a drain valve triggered by a condensation level sensor.

Abstract: A counter balanced effluence transfer system for the transfer of effluence from a source container into a receiving reservoir comprises a receiving reservoir having a cover plate and a reservoir top opening, and a counter balanced mechanism located above the receiving reservoir, which includes a pivot point, a source-side member attached to one side of the pivot point and a balance-side member attached to the other side of the pivot point. While the size and weight of the source-side member are made the same as those of the balance-side member, an angular asymmetry is built in between the source arm and the balance arm so that the gravitational source torque Ts and the gravitational balance torque Tb are made unequal. Upon release of the counter balanced mechanism with a latching starting mechanism, the counter balanced mechanism would automatically rotate and complete the pouring of source effluence into the receiving reservoir.

Abstract: A automatic effluence transfer system for the transfer of effluences from a source container into a receiving reservoir comprises a receiving reservoir having a cover plate and a reservoir top opening, and a mechanism located above the receiving reservoir, which includes a pivot point, and an actuated force mechanism that would, once activated, automatically rotate and complete the pouring of source effluence into the receiving reservoir.

Abstract: Waste slurry containing dissolved metal from e.g., CMP is subjected to sludge-free processing. Embodiments include separating the waste slurry with a solids filter into a solids-free dissolved metal-containing liquid filtrate portion and a concentrated solids-containing portion, removing the dissolved metal from the filtrate by means of an ion exchanger, back-washing the concentrated solids-containing portion with metal-free effluent from the ion exchanger to further reduce its dissolved metal content, discharging the washed concentrated solids-containing portion to a waste drain, removing the metal from the ion exchanger in solution form, and optionally extracting solid metal from the solution by electrowinning.

Abstract: The sealing device disclosed herein is designed for providing an air tight seal between a door casing and the sides of a vehicle positioned adjacent the casing. It comprises an elongated rigid angular profile having flanges which define a channel-shaped space therebetween and a resilient and collapsible pad structure fastened in the channel-shaped space between the flanges of the angular profile. The pad structure includes a collapsible spongy material enclosed in an air tight envelope, and the interior of the pad communicates with a vacuum source. In its distended position, the material inside the pad structure will cause the pad to expand a considerable distance beyond the flanges of the angular profile so as to abut the sides of the vehicle thereby providing an air tight seal. When a vacuum is applied to the collapsible material, the pad structure will collapse and be retracted almost completely into the channel-shaped space between the flanges of the profile.
