Abstract: In accordance with the present invention, there is provided an increased efficiency strainer system which is particularly suited for use in the emergency core cooling system of a nuclear power plant. In certain embodiments of the present invention, the strainer system includes one or more strainer cassettes or cartridges, with each such cassette or cartridge including a plurality of strainer pockets disposed in side-by-side relation to each other. In these embodiments, multiple cassettes or cartridges may be assembled together to form a strainer module of the strainer system. The strainer pockets of the cartridge each define an inflow end. Within the cartridge, or the module including multiple cartridges, the inflow ends of one or more of the strainer pockets may be enclosed by an elastic metal membrane. When in a closed position, the membrane prevents liquid flow into the corresponding strainer pocket via the inflow end thereof.

Abstract: Electronic systems, such as printing systems, often use components that have integral memory. The integral memory can be used to store information about the component. In some printing systems this memory includes a portion that stores a value indicative of a print yield. Disclosed is a method and system for allowing the memory to have data indicative of an increased print yield.

Abstract: In accordance with the present invention, there is provided a fluid or liquid barrier packing system which is adapted to minimize VOC emissions, while also providing live-loading and continuous load monitoring functions. The components of the packing system (including the liquid barrier) are adapted to be installed in a traditional stuffing box of a valve utilizing a top entry method, and without the necessity of having to inject the liquid through any side ports of the valve. The packing system reduces leakage levels as required by low emission leakage specifications by creating a reverse osmosis effect, limiting the diffusivity of a gas through the packing elements of the system. Thus, the packing system of the present invention provides a simplified method to load and monitor a barrier in the stuffing box of the valve to slightly higher pressure than processed fluid pressure.

Abstract: Image recording devices, such as electrophotographic devices, laser printers, copiers, and fax machines, often have a cartridge that utilizes an encoder wheel assembly in addition to or instead of a chip for determining toner load. It may be desirable to alter the encoder wheel or part of the cartridge, either by the printer or the cartridge, to permit a deliberate end of life function situation that requires the replacement of the cartridge, encoder wheel, or encoder wheel assembly components. This thereby controls the remanufacture or replacement of the toner cartridge in a way that is desirable to the manufacturer and prevents unauthorized refilling of the cartridge.

Abstract: A cartridge drive gear assembly for holding a drum coupling includes a drive gear having an outer surface and an inner surface, the inner surface including inner projections which extend into the interior of the drive gear and includes at least two voids disposed on opposing sides of the inner projections, and at least one slot disposed in the inner surface

Abstract: A linear displacement control valve comprising a valve body having a valve bonnet cooperatively engage thereto. The body and the bonnet collectively accommodate a valve trim which comprises a flow control element and a complementary spindle. The spindle is preferably attached to a reciprocally movable valve stem of the control valve via a stem adaptor. The stem adaptor is adapted to allow for some measure of “float” between the spindle and the flow control element as may be needed to accommodate any misalignment therebetween. The spindle is uniquely configured such that when used in conjunction with the flow control element, the trim is capable of providing low end flow control at a higher level of accuracy and/or wider rangeability.

Abstract: An anti-surge system capable of anticipating a surge event in a compressor for readying the actuator to quickly actuate the anti-surge valve from the closed position to the open position. The control system includes a compressor surge controller configured to transmit a signal to the valve positioner when the operating point of the valve is approaching the surge control line. The compressor surge controller may monitor an operating margin equal to the difference between the operating point and the surge control line, and when the operating margin falls below a prescribed threshold, the compressor surge controller may send a signal to the positioner. In turn, the positioner may vent some pressure from the actuator. In this way, the dead time of the anti-surge valve on the valve seat is minimized and the valve will react more promptly to an opening signal.

Abstract: Image recording devices, such as electrophotographic devices, laser printers, copiers, and fax machines, often have a cartridge that utilizes a drive gear to transmit rotational force from the printer to the print cartridge. Also, it is desirable to remanufacture print cartridge both to reduce waste and to save resources. Therefore, it may be desirable to provide a drive gear mechanism that is easily replaced or reused when a print cartridge is remanufactured.

Abstract: A method of operating a cartridge chip installed in an imaging device includes: causing, by the cartridge chip, the imaging device to enter an error condition; monitoring the timing or sequence of communication signals received from the imaging device during at least a portion of the error condition; and operating, based on the timing or sequence of the communication signals received from the imaging device during at least a portion of the error condition, in a first mode of operation compatible with a first type of imaging device or in a second mode of operation compatible with a second type of imaging device.

Abstract: A drive gear for a generally cylindrical imaging component. The drive gear includes a body for engaging the generally cylindrical imaging component; a cylindrical shaft attached to the body, the cylindrical shaft having an end surface; and three prongs extending longitudinally outward from the end surface. Each prong may include an extension member extending perpendicular to the prongs and the cross-sectional area of the extension members may be less than the cross-sectional area of the prongs.

Abstract: A method of operating a cartridge chip installed in an imaging device includes: causing, by the cartridge chip, the imaging device to enter an error condition; monitoring the timing or sequence of communication signals received from the imaging device during at least a portion of the error condition; and operating, based on the timing or sequence of the communication signals received from the imaging device during at least a portion of the error condition, in a first mode of operation compatible with a first type of imaging device not having a list of banned serial numbers or in a second mode of operation compatible with a second type of imaging device having a list of banned serial numbers.

Abstract: In accordance with the present invention, there is provided a steam desuperheater which is integrated into a steam line. The steam desuperheater comprises a segment of steam pipe having one or more spring loaded spray nozzles attached thereto.

Abstract: A control valve which includes a uniquely configured seat ring outfitted with flow passages adapted to operatively interact with a valve plug in a manner providing prescribed pressure reduction characteristics in a fluid flowing through the flow passages. The seat ring of the control valve of the present invention is preferably fabricated through the use of a direct metal laser sintering (DMLS) process. The use of the DMLS process to facilitate the fabrication of the seat ring in the control valve allows for the creation of more intricate and complex flow passages therein. Such increased intricacy/complexity provides better flow range/rangeability within the control valve.
