Edge bead removal apparatus
An edge bead removal apparatus is provided. The edge bead removal apparatus includes a clamping unit configured to clamp a cylindrical reticle and cause the cylindrical reticle to incline with a pre-determined angle and to rotate around a central axis. The edge bead removal apparatus also includes an edge bead removal solvent nozzle configured to spray an edge bead removal solvent to remove edge beads on both edges of the cylindrical reticle.
Non-Thermal Drying Systems with Vacuum Throttle Flash Generators and Processing Vessels
A system is disclosed for drying a material to liberate a substance such as a liquid having a vapor pressure from solids and/or dissolved substances in the material. The system includes a plenum chamber and a blower providing a stream of air to the plenum chamber. An outlet communicates with the plenum chamber and a velocity accelerator is disposed downstream of the outlet. The velocity accelerator is arranged to receive air from the outlet of the plenum chamber into a progressively narrowing interior passageway terminating at a downstream choke point orifice. The choke point orifice discharges into a larger diameter discharge region. A throttle body is disposed in the discharge region and is selectively movable toward and away from the choke point orifice to decrease or increase the volume of the discharge region. A passageway is formed through the throttle body for receiving flashed material from the discharge region and conveying the material in a downstream direction. Also disclosed is a system for drying materials contained within a processing vessel wherein flash generators with vacuum throttles are used to maintain drying conditions within the vessel and to remove liberated substance from the processing vessel.
APPARATUS FOR MAKING A FILM
Apparatus for making a film includes a container for holding a quantity of flowable polymeric material. A die in fluid communication with the container receives polymeric material from the container and extrudes the polymeric material into a thin and flat web. A chill roll adjacent to the die receives the web exiting the die, and is cooled to a temperature that promotes curing of the polymeric material into a solid state. An air knife located adjacent to the chill roll is configured to direct air from the air knife onto the web on the chill roll. The air knife is arranged with respect to the chill roll so that at the location where air exiting the air knife impinges upon the chill roll air from the air knife is prevented from getting under the web on the chill roll.
DISTRIBUTION PLATE FOR FORMING FLUIDIZED BED, AND FLUIDIZED BED DRYER
Provided is a distribution plate used for forming a fluidized bed in a reactor such as a dryer or incinerator, the distribution plate exhibiting enhanced drying efficiency and operational efficiency, by achieving both dischargeability at the end of operation, and stable fluidized bed formation during operation. A distribution plate for forming a fluidized bed is made up of a base plate, a plurality of small holes provided in the base plate, and a chimney deck in which respective chimneys are disposed in the small holes. Each chimney has a slit-shaped first opening portion opened in a predetermined direction, and a second opening portion opened in a different direction at a height position above the first opening portion.
Surface dryers producing uniform exit velocity profiles, and associated systems and methods
Surface dryers having uniform exit velocity profiles, and associated systems and methods are disclosed. Surface dryers in accordance with certain embodiments include a housing, a gas driver positioned in the housing, an inlet aperture formed in the housing and positioned upstream of the gas driver, and a nozzle carried by the housing and positioned downstream of the gas driver. The nozzle can have an indentation forming a convergent portion positioned to accelerate the flow of air and a divergent portion positioned to decelerate the flow of air.
Laundry treatment apparatus
A laundry treatment apparatus includes a connection duct into which air inside a drum, which provides a laundry accommodation space, is discharged. The laundry treatment apparatus also includes a discharge duct configured to extend in a longitudinal direction of the drum and connected to the connection duct and a filter assembly including a filter unit located in the discharge duct to filter air and an impurity remover unit configured to remove and compress impurities remaining on the filter unit. The laundry treatment apparatus further includes a drive unit secured to the impurity remover unit. The drive unit is configured to reciprocate in a longitudinal direction of the filter unit to allow the impurity remover unit to reciprocate over a predetermined area of the filter unit.
Device and methods for rapid drying of porous materials
An apparatus and method for quickly drying porous materials. A sealable chamber is connected to a cold trap which is connected to a vacuum pump. A sample is placed inside the sealable chamber. The vacuum pump is turned on and air is evacuated through the cold trap to the vacuum pump. An infrared lamp may be used to heat the chamber and sample therein directly or heated air may be allowed to enter the sealable chamber. Air may be drawn directly from the sealable chamber to the vacuum pump bypassing the cold trap. Various parameters may be used to determine if the drying process is complete, including the degree of vacuum achieved in the chamber.

METHOD OF PIPELINE INTERIOR DRYING
Pipeline transport of hydrocarbons detect the moisture accumulation location along the pipeline and increase effectiveness of the drying process. Drying air moisture content reduction is obtained by the installing additional intermediate air drying devices in by-pass lines at block valve station along the pipeline to be dried. Purging is proceeded until normalized dew point temperature value of the outcoming air being achieved. Purging is interrupted for 12 hours or more, both upstream and downstream ends of pipeline leaving hermetically closed, and resumed with intermediate air drying devices disabled, continuously measuring the moisture content of the outcoming drying air, fixing the moment when the moisture accumulation in the surrounding air.
Solvent scavenger for a desolventizer toaster using a vapor recovery system
An improved desolventizer-toaster (DT) unit is used for removing traces of a hydrocarbon solvent from a mass of vegetable particles of oil. A conventional DT unit has within a housing, a set of solvent removal trays and a main ejector transporting solvent vapor and steam from below the tray set to between a pair of the trays in the set. The improved DT unit has a further scavenger tray between an inlet of the main ejector and the housing floor. A scavenger ejector transports solvent vapor from between the scavenger tray and the housing floor before it exits from the unit, to the space between the tray set and the scavenger tray.
