Granted: 1999-05-18
Abstract: Cooking liquors of significantly different sulphidity (e.g. one having a sulphidity about 30-40% and the other a sulphidity of above 40%, e.g. about 60-70%) may be produced in a simple energy-efficient manner. Black liquor is treated to recover chemicals, and the chemicals are dissolved to produce green liquor, which is clarified, as is conventional. The temperature of a firstportion of the green liquor is decreased to effect crystallization of sodium carbonate in the green liquor by expanding the green liquor in at least two (andtypically more than three) stages with vapor being produced during expansion. The sodium carbonate crystals produced are separated from the first portion of green liquor to produce a green liquor with high sulphidity (greater than about 40%) and this high sulphidity liquor may be heated by bringing it into direct heat exchange relationship with at least part of the expansion vapor (in a number of different stages). The separated sodium carbonate crystals are dissolved to produce a low sulphide content alkaline solution, which may be heated by bringing it into indirect heat exchange relationship with a second part of the expansion vapor. Heat recovered from the last expansion stage may be used to assist in dissolving the sodium carbonate crystals, as by using a heat pump system. The second portion of the clarified green liquor is used to produce a second green liquor having a sulphidity at least 10% lower than the high sulphidity green liquor.

Title: Laser scanning system and scanning method for scanning bar codes
Inventor: DVORKIS PAUL
IPC: G06K7/14
Filed: 1995-10-25
Granted: 2007-05-29
Abstract: A scanner determines whether a target is a bar code symbol and, if so, whether that symbol is one-dimensional or two-dimensional. For two-dimensional symbols, the scanner aligns a scanning pattern with the symbol and expands the scanning pattern to reach only to the top and bottom edges of the symbol, not beyond. The scanner also has a microprocessor-control scanning engine that uses a coil to drive a scanning element and pick up feed back signals from the scanning element. A pulse-width-modulated regulator also provides fast and efficient operation for driving the coil. The scanning engine can also be designed to generate a pattern that precesses across the target, and a powerful interface to the scanning engine allows decoding and control logic to work efficiently with and independently of the scan engine.

Title: Instant-on valve construction for high pressure gas
Inventor: KHADIM NEIL
IPC: F17C13/04
Filed: 1996-07-15
Granted: 2002-01-15
Abstract: A valve construction  for high pressure gases, allowing rapid opening and closing, includes a main body with inlet and outlet passages, and a guide sleevehaving a primary and a secondary piston slidably mounted within the sleeve, the primary piston being adjacent a closure at one end of the sleeve, and the secondary piston being at the end of the primary piston which is remote from the closure.  The secondary piston supports a seal for closing the gas outlet passage when the secondary piston is remote from the closure.  The secondary piston has an axial passage with an elongate member movable therein, the elongate member being fixed to the primary piston.  A valve means is provided between the axial passage and  the  elongate member, the valve means being open when the bleed orifice is closed.  A peripheral seal between the secondary piston and the sleeve acts to restrain the axial movement of gas.  An access passage connects the periphery  of the secondary piston with a location on the axial passage, while a passageway  in the secondary piston connects the region between the first and second pistons with the bleed orifice chamber.  An electrical coil acts to generate a magnetic field.  The valve construction  thus defined is in equilibrium  when the coil is de-energized, the seal means closing the gas outlet passage, the closure portion closing the bleed orifice, and the primary piston being furthest remote from the closure.  When the coil is energized,  the  primary  piston moves toward the closure until the valve means closes, lifting the closure portion off the bleed orifice and permitting gas  to  escape from  around the  primary  piston, through said passageway, and out the bleed orifice, thus resulting in an increase in the pressure differential across the peripheral seal.

Title: Operation right interlinking method and cooperative working method for shared application programs
Inventor: MIZUNO HIROMI
IPC: G06F9/46
Filed: 1997-01-07
Granted: 2002-08-20
Abstract: The invention provides an operation right interlinking method and a cooperative working method wherein, when a plurality of shared application programs operate cooperatively with each other to effect a cooperative work, operation rights of the shared application programs are always possessed by a same terminal so that a work can be performed efficiently without an inconsistency.  To this end, the operation rights of the shared application programs are controlled in an interlinking relationship with each other.  When a request for an operation right is issued to a first application program of a first terminal, the first application program requests a first application program of a second terminal for transmission of the operation right and sends an operation right change notification to a second application program of the first terminal whose operation right is to be interlinked with the first application program.  Upon reception of the operation right change notification, the second application program of the first terminal requests a second application program of the second terminal based on the operation right change notification.
