Patent CA-2162939-A1 (CA)
Title: Terabit per second packet switch
Inventor: CLOONAN THOMAS JAY
IPC: H04L12/56
Filed: 1995-11-15
Abstract: A physically realizable one terabit or more ATM packet switch 10 A that has a large number of input interfaces connected to a single stage switching fabric 14A which is in turn connected to a number of output modules 160-16 m, accordingto the generic growable packet switch architecture. This ATM packet switch 10 A is different from other growable packet switches in that it has a single stage switch fabric (14A or 14B) controlled by an out-of-band controller 20, yet it has significantly reduced complexity with respect to comparably sized electronic crossbar switches or their isomorphs. This ATM packet switch architecture is so flexible, it can be extended to provide variable length packets, circuit switched connections and fault tolerant redundant circuits using the same switch fabric and out-of-band controller architectures.

Patent CA-2170594-A1 (CA)
Title: Minimum adverse environmental impact pulp mill
Inventor: NYKANEN TUOMO
IPC: C01B7/01
Filed: 1994-07-27
Abstract: Effluents are minimized from a cellulose pulp mill having a recovery boiler by concentrating liquid effluents from the bleach plant and/or liquid spills from process streams, incinerating the concentrated effluents in the recovery boiler, removing particles present in the flue gases from the recovery boiler to produce an ash including salts containing potassium and chloride, and sulfur compounds, and removing the potassium and chloride from the ash while returning the sulfur containing compounds to the recovery loop, so as to balance the sulfur, chloride and potassium levels in the mill. The sulfur is typically returned directly to a stream of black liquor just before entry into the recovery boiler. Green liquor is produced from the melt, which preferably is treated to remove metals from it prior to caustization (e.g. by sedimentation and/or filtration), and prior to green liquor crystallization to produce sodium hydroxide.

Title: Dual string assembly for gas wells
Inventor: MITCHELL BRYSON JAMES
IPC: E21B33/047
Filed: 1996-03-19
Abstract: A dual completion for gas wells includes a dual base with a primary hanger incorporated in the base. Primary and secondary coiled tubing strings extend through the base at a downwardly converging angle of 2° or less. The dual base is mounted on an annular blowout preventer. At the top of the annular blowout preventer is a tubing centralizer that aligns the two tubing strings parallel to one another. The blowout preventer has two side ports below the bladder allowing the operator to produce gas from the annulus, to flare gas to atmosphere or to pump in kill fluid in the event of an emergency. The alignment of the tubing strings allows production recorders to be run in either string.

Inventor: MIYAUTI SATOSI
IPC: G01N33/68
Filed: 1995-02-17
Abstract: A method for assay of normal aggrecan wherein normal aggre-can capable of binding hyaluronan is separated from proteoglycan incapable of binding hyaluronan so that only normal aggrecan can be detected, and a measurement kit used for the assay.   Normal aggrecan thus separated is detected with a means for detection of proteoglycan.     The specimen is preferably synovial  fluid from the joint to be examined.    A method for evaluation of information on a  joint wherein  information on the amount of normal  aggrecan and the amount of total proteoglycan  in the specimen is detected with said method and said measurement kit for assay of normal aggrecan, such information is compared with the  previously  obtained  information  on  the  amount  of  said substances  in  synovial  fluid  from  a  normal  joint,  and  the information is evaluated to be the one derived from a normal joint or a pathological joint based on the absence or presence of significant difference.    Presence of significant difference is considered to indicate a disease selected among a group of diseases  consisting  of  osteoarthritis,  rheumatoid  arthritis, traumatic arthritis, and gout.      This invention is usable for biochemical diagnosis of joint diseases in the field of orthopedics.    Determination of the concentration of normal aggrecan and the percentage of normal aggrecan  in total  proteoglycan  is  useful,  for differentiation between  a  normal   joint  and  a  pathological   joint,   for understanding of the pathological conditions, such as the type of the joint disease and estimation of the prognosis, and also for evaluation of the effect of therapies.

Title: Process for treating a waste material
Inventor: GOLLEY CHRISTOPHER ROBIN LANGD
IPC: B01D21/24
Filed: 1996-10-30
Abstract: A method of treating a dilute aqueous suspension of solid particulate material comprising waste material from a process for recovering petroleum from oil sand includes diluting the suspension with at least 75% of its own volume of water thereby to increase the settling rate of the particulate material and allowing the particulate material to settle to form a concentrated solid sediment.      The treated suspension may have been obtained from a process in which an alkaline solution is used to treat the oil sand.  The water from which the concentrated solid sediment is separated may be returned to the process for recovering petroleum from oil sand.  The solid sediment may be transferred to a separation vessel in which it is fractionated into a coarse particle fraction and a fine particle fraction.  The fine particle fraction may comprise essentially particles having an equivalent spherical diameter not greater than 3µm.      The concentrated solid material recovered may be calcined to form a pozzolanic material.

Abstract: La présente invention constitue un perfectionnement des étapes combinées de fractionnement de la déséthanisation et du passage en colonne de séparation C2 destinées à la séparation de l'éthylène et de l'éthane. On ajoute des étages théoriques (C200A) à la section de rectification d'un déséthaniseur au-dessus d'un dispositif de soutirage latéral (202) de liquide ou vapeur. Conformément à la présente invention, on obtient, dans un courant de tête, un produit éthylénique de qualité polymère comportant jusqu'à 30 % de l'éthylène présent dans l'alimentation du déséthaniseur. On parvient à une récupération moins importante à un même degré de pureté de l'éthylène ou à une récupération plus importante à un degré de pureté inférieur de l'éthylène en faisant varier le niveau de récupération ou le nombre d'étages supplémentaires dans la section de rectification. La mise en oeuvre de cette invention permet de parvenir à une réduction globale du nombre total d'unités auxiliaires froides destinées aux condenseurs de tête du déséthaniseur et de la colonne de séparation C2 située en aval.
