Abstract: The process according to the present invention relates to the treatment of wastewater discharged from a bleach plant and more particularly treatment of bleach plant alkaline wash filtrate from treatment-steps and/or delignification/bleaching-steps of pulp. Further improvements of known processes are needed for solving the problems associated with the recovery of alkaline filtrates into the chemical recovery system. According to the process of the present invention, alkaline wash filtrate from treatment steps and/or delignification/bleaching-steps of pulp is treated in a process by the following steps: i) treating at least a part of the alkaline filtrate in order to produce an alkaline concentrate enriched in high molecular weight dissolved organic compounds and a stream depleted in organic compounds, where the share of the alkaline concentrate to the total amount of the alkaline filtrate corresponds to a volume reduction factor (VRF) in the range of from about 2.0 up to about 7.5; ii) withdrawing the depleted stream; iii) collecting at least a part of the alkaline concentrate from step i) and using the concentrate as wash or dilution water in brownstock washing fiberline with a dilution factor of up to about 4.0, where at least a part of said washing filtrate is brought to the chemical recovery system.

Title: Method and apparatus of producing liquid disperse systems in liquid
Inventor: KOZYUK OLEG VYACHESLAVOVICH
IPC: B01F5/06
Filed: 1999-02-05
Abstract: A method and apparatus for producing a liquid disperse system in a flow-through channel is described. The flow-through channel (1) has first and second chambers (4, 5). The liquid in the first chamber (4) is maintained at a steady pressure P1-. The liquid is passed through a localized flow constriction (2) creating cavitation liquid jets that flow into the second chamber (5). The dynamic pressure of the liquid jets is govern by the equation pv2/2>=0.15 P1 where p is the density of the cavitation liquid jet and v is the velocity of the cavitation jet. Cavitation bubbles are produced in the cavitation liquid jets between 1 x 10-6 m and 1 x 10-2 m. The pressure in the second chamber P2 is maintained such that P1/P2 is <=9.8. The liquid disperse system is produced by the collapsing of the cavitation bubbles under static pressure P2 an the second chamber. The pressure P2 in the second chamber is maintained by a localized resistance at an outlet of the second chamber (5). The localized flow contraction may be shaped to produce cavitation liquid jets which are cylindrical, ring-shaped, or flat shaped. The liquid flow may be passed through the flow-through channel a number of times to further increase the production of liquid disperse systems.

Abstract: A retracting needle syringe includes a barrel having a chamber, an open proximal end and an open distal end. A plunger is slidabiy positioned in fluid-tight engagement with an inside surface of the barrel. The plunger has an elongated cavity in its distal end and a cover element sealing the cavity. A needle assembly at the distal end of the  barrel includes a needle cannula having an inner hub having an open proximal end and a dista l end connected to the needle cannula so that the lumen of the cannula is in fluid  communication with the chamber. A flange on the inner hub is connected to a proximal end o f an outer hub so that the needle cannula projects distally outwardly from a distal end of the outer hub. A spring is contained between the inner hub and the outer hub. A circular release element is movably connected to a proximal end of the flange. The release element has a  distal end and a sharp proximal end projecting into the chamber, wherein distal motion of the plunger will cause the sharp proximal end to cut through the cover element and the distal end of the release element to dissociate an outer portion of the flange from an inner portion of the flange allowing the spring to expand and move the needle cannula into the cavity.

Inventor: SOANE DAVID S
IPC: C08B3/12
Filed: 1999-03-23
Abstract: La présente invention concerne des composés et des procédés permettant de modifier une matière pour en changer les propriétés. L'invention concerne également divers produits obtenus grâce à ces procédés. Selon une réalisation, le procédé consiste à prendre une matière comprenant au moins un groupe fonctionnel modifiable et à la faire réagir en présence d'une base contrariée avec un groupe acyle hydrophobe activé de façon à le lier par covalence aux groupes fonctionnels modifiables présents sur la matière. Le matériau modifié peut ainsi être un glucide, les groupes fonctionnels modifiables présents sur la matière étant des hydroxyles. On peut ainsi modifier des matières telles que la cellulose en les faisant réagir, en présence d'une base contrariée telle que la tripentylamine, avec un chlorure acide ou un anhydride acide comprenant un groupe acyle hydrophobe. On recherche alors à lier aux hydroxyles présents sur la cellulose les groupes acyles hydrophobes de façon à augmenter l'hydrophobie de la cellulose. L'invention concerne également des procédés et des composés convenant pour modifier des matières de façon à en améliorer des qualités telles que la résistance, la répulsion des graisses, la résistance à la salissure, et l'infroissabilité.

IPC: H02M7/5383
Filed: 2001-01-12
Abstract: An electronic transformer consisting of a square wave power oscillator having a diode reverse capacitance serving as frequency tuning, wherein said power oscillator connected to a dc source typicly derived from the ac outlet and said generator is driving a transformer having substantial leakage inductance and the primary of said transformer is connected through a capacitor that forms a resonant circuit with said leakage inductance.    A second capacitor is connected to the junction of said first capacitor and transformer primary and a resistor are in series with said second capacitor . The voltage developed on said first resistor is proportional to the current in the transformer primary and after rectified it is fed to a diode with apritiable reverse capacitance. This capacitance then will decrease in response to the current and will increase the frequency of said power oscillator and in turn will limit said current to a safe value.
