Abstract: A display system includes a display panel, a backlight and a reinforced reflective polarizer disposed between the display panel and the backlight. The reinforced reflective polarizer includes a first layer formed from a polymer matrix embedded with inorganic fibers. The reinforced reflective polarizer also includes a second layer attached to the first layer. The second layer comprises a reflective polarizing layer.

Abstract: Radiation curable thermal transfer elements including a substrate and a light-to-heat conversion layer overlaying the substrate, and processes to make the thermal transfer elements. The light-to-heat conversion layer is derived from a radiation curable material capable of being cured by exposure to radiation at a curing wavelength and an imaging radiation absorber material not substantially increasing radiation absorbance at the curing wavelength. The radiation curable transfer elements can be used in processes for making organic microelectronic devices.

Abstract: Inkjet printing apparatus for use with radiation curable ink includes a sensor for sensing the amount of radiation emitted by a source of radiation. A controller is connected to the sensor and is operable to vary the amount of radiation emitted by the radiation source in accordance with a signal received from the sensor. A drive mechanism moves the source of radiation to a location laterally offset from the substrate where the sensor is positioned.

Abstract: An apparatus for classifying a mixture of fine and coarse particles in a fluid stream by size or density comprises a housing, a boundary layer momentum transfer device, and an inlet flow control mechanism. The housing comprises an inlet, an interior chamber, and a fine particle outlet. The boundary layer momentum transfer device comprises a plurality of disks stacked in spaced, parallel relation in the interior chamber. The disks are rotatable about a disk axis. The disks have respective central openings cooperatively defining a plenum having a closed axial end and an opposing open axial end. The plenum communicates with spaces defined between each adjacent disk to cooperatively define a fine particle flow path from the interior chamber, through the spaces, through the plenum and the open axial end thereof, and to the fine particle outlet. The inlet flow control mechanism communicates with the interior chamber and provides an adjustable inlet flow path into the interior chamber.

Abstract: A radial inflow centrifugal filter device for separating fine particulates from a fluid flow, including a rotatable plurality of hollow parallel disks mounted in spaced apart relationship and attached via spacers to a tube. The hollow drive tube is in flow communication with the interior hollow plenum of the disks which is at a lower pressure relative to the open space between the disks. Rotating the tube causes the disks to rotate. Particulate-laden fluid is allowed to enter the filter device at the perimeter of the rotating disks and experiences a change in momentum due to the interaction of boundary layers of fluid established on each side of every disk. The centrifugal force imparted to both the fluid and particulates causes them to be separated in opposite directions.
