Abstract: A portable electronic device may include a housing member, a rear cover coupled to the housing member, and a top module coupled to the housing member and including a front cover defining an exterior surface and an interior surface opposite to the exterior surface, a display stack attached to the interior surface of the front cover and comprising a flexible circuit element extending from a side of the display stack, a frame member attached to the interior surface of the front cover and extending at least partially around a periphery of the display stack, and an encapsulating structure positioned between the frame member and the display stack and at least partially encapsulating a portion of a peripheral side of the display stack and the flexible circuit element. The encapsulating structure may cover at least a portion of a bottom side of the display stack.

Abstract: A microparticle filter suitable for filtering microparticles from effluent from a textile treatment apparatus. The filter comprises a filter chamber comprising chamber walls, an inlet and an outlet. The filter also comprises a filter medium contained within the filter chamber. The filter medium is configured to filter microparticles from the effluent forming a filter residue and providing a filtered effluent to the outlet. The filter comprises a filter residue collection chamber located external to the filter chamber, and a filter residue removal apparatus. The chamber walls comprise an opening and a moveable member movable between a first and a second configuration; wherein: in the first configuration the moveable member cooperates with the chamber walls to seal the filter chamber so entry of the effluent into the filter chamber is through the inlet only and exit of the filtered effluent from the filter chamber is through the outlet only.

Abstract: This invention relates to a filter which is especially for filtering microfibres which can, for example, originate from the washing of textiles. The filter is rotatable around an axis of rotation. The filter provides good filtering efficiency and improved resistance to blocking.

Abstract: A laser projection system preferably for use in commercial motion picture theaters and other large screen venues, including home theater, uses optical fibers to project modulated laser beams for raster scanning on the screen. The emitting ends of the optical fibers are arranged in an array such that red, green and blue spots are simultaneously scanned onto the screen in multiple lines spaced one or more than one scan line apart. The use of optical fibers for laser beam projection eliminates the need to use complex optics, and enables the scanning of small, high resolution spots on the screen. The use of optical fiber also permits convenient packaging and permits replacement, upgrading or modification of the system components. The scanning of multiple lines simultaneously is accomplished by reordering the video signal with a microprocessor controller component to write lines in a sequence after repeated vertical sweeps to form a complete picture.

Emitting ends of optical fibers are arranged in an array such that red, green and blue spots are simultaneously scanned onto the screen in multiple lines spaced one or more scan lines apart. Use of optical fibers enables scanning of small, high resolution spots on screen, and permits convenient packaging and replacement, upgrading or modification of system components. Simultaneous raster scanning of multiple lines enables higher resolution, brightness, and frame rates with available economical components. Fiber-based beam coupling may be used to greatly enhance the flexibility of the system.

Abstract: A circuit board on which the electronic components providing power to a series of light sources is positioned as near as possible to light sources in order to minimize parasitic energy losses which would be introduced by lengths of wiring. The light sources are usually elongate tubular Cold Cathode Fluorescent Tubes arranged parallel to one another in a single plane and the circuit board may be mounted directly over the light sources, towards one end of the tubes. Standard PCB board-to-board connectors may be provided at an edge of the circuit board and a further circuit board provided with a series of conductive tracks may provide both a mechanical and electrical connection between the circuit board and the light sources. A power distribution method is also disclosed in which both current and temperature of the light sources are monitored and regulated in order to extend the lifetime of the light sources and to stabilize their brightness.

Abstract: In the preparation of poly(m-phenylene isophthalamide) filaments, hydrogen chloride is removed from as-produced amide solution of poly(m-phenylene isophthalamide) by contact with basic ion exchange resin.

Abstract: Hydrogen chloride is stripped from spent basic ion exchange resin by treatment with a solution of a tertiary amine in an amide solvent. The eluent solution is treated with anhydrous ammonia to precipitate ammonium chloride. The solution of tertiary amine in amide solvent is separated from the precipitate and may be used to regenerate spent resin.
