Patent CA-2246922-A1 (CA)
Inventor: DESROCHERS DARREL J
IPC: F16K3/02
Filed: 1998-09-09
Abstract: A knife gate valve is constructed of two body members bolted together about a resilient gate seat. The two body members and the resilient gate seat include sets of axially aligned bolt holes through which machine bolts extend. Matching flanges on the body members form a recess for receiving the resilient gate seat, thereby constraining its movement and preventing its deformation when the knife gate is closed. The matching flanges also facilitate the uniform tightening of the machine bolts during gate valve assembly. The resilient gate seat includes tab portions at its ends for improved retention and rib portions along its length for improved sealing. The resilient gate seat includes a seating contact area that has a width that is less than the thickness of the knife gate for reducing friction between the knife gate and the gate seat.

Title: Kraft pulping process
Inventor: BERRY RICHARD MCKINNON
IPC: D21C7/14
Filed: 1999-01-18
Abstract: Sodium chloride is removed from pulping chemicals used in a Kraft pulping process by the use of a snake-cage polyelectrolyte ion exchange resin, coupled with removal of sulfide prior to treatment, or treatment of chemicals which are already low in sulfide. In one aspect of the invention, dust is collected from exhaust gases produced in the black liquor recovery cycle and is dissolved in water to produce a solution containing sodium chloride and sodium sulfate. The solution is filtered to yield a solid product and a filtrate solution. The filtrate solution is fed to an ion exchange unit which removes chloride and produces a purified sodium sulfate product. The sodium chloride is removed from the ion exchange resin by water elution, and useful recovered chemicals are recycled to the recovery cycle of the Kraft process. In one embodiment, only a portion of the dust is dissolved so that the solid product produced by filtering is primarily sodium sulfate, and that sodium sulfate is recycled to the recovery cycle of the Kraft process. In another aspect of the invention, white liquor from the pulping process is treated directly after oxidizing sulfide to sulfate. After removal of sodium chloride in the ion exchange unit, the treated white liquor can be used as a source of sodium hydroxide for oxygen delignification, and the effluent from the oxygen delignification stage can be returned to the process.

Abstract: A system and method for providing computerized, knowledge-based medical diagnostic advice. The medical advice is provided to the general public over a network, such as a telephone network with the use of a telephone or the Internet with the use of an Internet access device. Alternatively, the medical advice can be provided to a patient in a stand-alone mode by use of a computer. The invention utilizes a list-based processing method of generating and executing diagnostic scripts. For the purpose of diagnosing a health problem of a patient, medical knowledge is organized into a list of the diseases to be considered. Each disease on the disease list includes a list of symptoms that is checked in a patient. Each symptom on the symptom list is then further described as a response to a list of one or more questions asked of the patient about the symptom. This triply-nested list structure is converted by suitable data structure transformations into a script that is stored. When a patient requires diagnosis, the script is played back as a sequence of questions. The responses of the patient are analyzed and converted into symptoms. The symptoms are accumulated into diseases. Finally the diseases are selected and reported as a diagnosis.

Abstract: In a chamber R1 which accommodates a transmission device comprising a drive pulley 8, a driven pulley 9 and a belt 10, a cover 51 is provided to cover the lower peripheral portion of the drive pulley 8 along the periphery. The drive pulley is positioned below the driven pulley, and raised portions 52 which are used for the detection of the rotational speed of the drive pulley are provided on the periphery of the drive pulley. The end surface 51bs of the cover facing the inner wall 54 of the pulley chamber is positioned away from the inner wall with a clearance V therebetween. In a vehicular transmission which is constructed in this arrangement, the amount of lubrication oil that flows near to the periphery of the pulley which is positioned lower is comparatively small. Thus, this arrangement restricts agitation of the lubrication oil, which may be caused by the raised portions of the rotating pulley. Therefore, loss in the rotation of the pulley and oxidation and degradation of the lubrication oil are effectively prevented.
