Patent CA-2136760-A1 (CA)
Inventor: TAVIS JOHN R
IPC: H02P25/02
Filed: 1993-05-17
Abstract: A variable reluctance transducer system incorporating digital control of parallel resonant circuits (L1C1, L2C1) including two inductive sensors (L1, L2) on each side of a flat diaphragm. The two parallel resonant circuits provide dual frequency signals for digital calculation to obtain a quotient of the frequencies, thereby substantially eliminating the resonant frequencies as a variable in the accuracy of the device. Manipulation of the produced quotient by a microcontroller (10) employing digital calibration tables stored in a programmable read only memory (14) allows calibration responsive to a temperature sensor (16), thereby substantially eliminating temperature induced error in the system.

Title: Completely concurrent cook continuous digester
Inventor: PROUGH J ROBERT
IPC: D21C3/24
Filed: 1993-09-28
Abstract: A conventional continuous digester is modified so as to provide a countercurrent cook throughout the entire height of the digester. Instead of connecting an upper mid-point extraction screen to a flash tank, that screen is closed off and extraction is provided at the top of the digester, utilizing an in-line drainer to remove some of the liquor and feed it to a flash tank. The liquor not removed recirculates through a pressure screen to an impregnation vessel, and then back to the digester. A cooling circulation is provided just below the top extraction. Valves are provided in the liquor discharged from the drainer and a conduit from the upper mid-point extraction which may be manipulated to return the digester to conventional operation, including the addition of white liquor to the bottom recirculation.

Title: Tubular elastomer damper
Inventor: CULLEN LAWRENCE I III
IPC: B64C27/51
Filed: 1993-10-18
Abstract: A tubular elastomer damper (11) has a central shaft (12) disposed within a housing (13) and surrounded by an elastomer member (14). Uniform strain is provided across the elastomer disposed between the central shaft and the housing by either tapering the length of the elastomer from an inner bonding surface (15) to an outer bonding surface (16) such that the radius times the length at each point along the elastomer is equal or by providing a first elastomer layer (28) adjacent the shaft (26) having a high fatigue strain/lower damping ability, a second elastomer layer (29) adjacent the housing (27) having a low strain higher damping ability and intermediate elastomer layer (30) of moderate strain and damping therebetween such that from the inner to the outer radius of the elastomer member, uniform strain is achieved. By providing uniform strain from the inner to the outer radius of the tubular elastomer damper,temperature increases due to localized high strains are avoided which are detrimental to damper performance. Optionally, axial cooling passages are provided within the elastomer member to dissipate heat to assure operation within design parameters,thus extending the life of the tubular elastomer damper.

Patent CA-2151541-A1 (CA)
Inventor: KOBAYASHI WILLIAM THORU
IPC: F23D11/38
Filed: 1995-06-12
Abstract: The invention relates to an improvement in atomizing methods and apparatus useful for combusting liquid fuel, such oil.  The atomizing methods and apparatus consistently produce liquid fuel streams having vary narrow spray angles.  The liquid fuel streams having very narrow spray angles can be produced even when a low liquid fuel flow rate is employed and even when a liquid fuel stream is atomized outside a liquid fuel passageway.  The production of the constant narrow spray angle liquid fuel stream allows the atomizing apparatus to operate for a long period without causing fouling problems even if they are sufficiently recessed from internal openings of refractory ports defined in the furnace wall.
