Patent CA-2238100-A1 (CA)
Inventor: GROUDININE ALEXANDRE VLADIMIRO
IPC: D21C3/04
Filed: 1996-11-13
Abstract: The invention relates to the paper pulp industry, specifically to a process for preparing a pulp cooking solution used for obtaining a fibrous semi-finished product. This involves saturating a solution of sodium carbonate in waste water obtained from the biological purification of paper industry effluent with a concentration of surplus active sludge of 18-40 g/l, having a sodium carbonate concentration of 1.55-2.5 wt.% in units of Na2O, or an alkaline hydrolysate obtained by treating waste water obtained from the biological purification of paper industry effluent with a concentration of surplus active sludge of 18-40 g/l with a mixed base containing 50-90 wt.%  sodium carbonate and 10-50 % calcium oxide, in a quantity of 1.55-2.50 wt.%  per unit Na2O at a temperature of 25-40 ~C with subsequent removal of the solid precipitate, at a temperature of 35-45 ~C until it accounts for 2.5-5.5 wt.% of the cooking mixture. The proposed process significantly increases the yield of fibrous semi-finished product and improves its physical and mechanical indicators. It also permits the use of waste obtained from the biological purification of paper industry effluent and widens the range of raw materials which can be used to produce pulp cooking solutions.

Title: Detecting abnormal reactions in a red blood cell agglutination
Inventor: SHEN JIAN
IPC: G01N33/53
Filed: 1998-07-30
Abstract: Abnormal reactions in a red blood cell classification by agglutination, are checked following centrifugation of a sample in a column of a cassette, the column containing microparticles. This is done by imaging the column on a detector array that is used to correlate the images with predefined red cell classes based upon the distribution of the images across the column. However, prior to the correlation step, abnormal reactions are checked for by detecting whether any of the following is present: i) errors that cause imaged features of the column or any pellet produced therein to be out of range; ii) hemolysis of the sample; iii) insufficient or too many blood cells present; iv) mixed field agglutination; and v) presence of fibrin at the top of the microparticles.

Patent CA-2249632-A1 (CA)
Inventor: AOKI HIROYUKI
IPC: B29K101/10
Filed: 1998-10-05
Abstract: An economical branch pipe liner bag is provided.  The branch pipe liner bag allows for a reduction in manufacturing cost, stabilized quality, and mass-production, and does not have any portion to be wasted when used.  One end of a tubular resin absorbent material impregnated with an unhardened hardenable resin is outwardly folded and pressed to form an extension which is sandwiched between separate flange forming members to form a flange at the one end of the tubular resin absorbent material, thus constructing the branch pipe liner bag.  Since the branch pipe liner bag has the flange formed at one end by integrally coupling the flange forming members, which are members separate from the tubular resin absorbent material, the flange forming members can be mechanically mass-produced independently of the tubular resin absorbent material, with the result that a manufacturing cost of these flange forming members is reduced, and consequently a manufacturing cost of the branch pipe liner bag is reduced.

Abstract: In a high speed multicast route searching method of searching information of a transmission port to which a received multicast packet is next transferred: a route address is formed by coupling a receiver address and a sender address in this order; one p-th power-of-2-branch tree node is configured by a collection of one two-branch tree node and two-branch tree nodes of p-1 stages totalling ((p-th power of 2) - 1) nodes just under the one two-branch tree node to form a p-th power-of-2-branch tree which is stored in a memory; not one bit but consecutive p bits of the route address coupling the receiver address and sender address in a received multicast packet in this order are checked at the same time; and in accordance with the values of the consecutive bits, a search tree stored in the memory is searched. In this manner, a search process can be completed by tracing nodes (the number of bits of a search key divided by p) times at a maximum, independently from the number of entries.
