Filed: 2001-01-03
Abstract: The process steam from the last evaporation stage and the unclean condensate are introduced into the first unit of a combined stripper/condenser while the rest of the steam flows to another condensers. The process steam and unclean condensate are brought to flow in opposite directions to cause a direct heat exchange resulting to the separation of volatile compounds from the condensate.        Purification of unclean condensate emanated from pulp production of chemical or semichemical pulp including evaporation of spent liquor under utilization of a cleaning plant having series coupled condensers comprises: (a) the process steam from the last evaporation stage and the unclean condensate are introduced into a combined stripper/condenser in opposite directions to cause a direct heat exchange, resulting separation of volatile compounds from the condensate; (b) the rest of the process steam flows to another condensers while the remaining process steam is cooled down indirectly leading to the contaminated water and turpentine to be condensed and collected together. Methanol is condensed from the first collected condensate that separates from the turpentine content. Turpentine is removed from the plant and the residual condensate leads back to the combined stripper/condenser. Methanol and primary cleaned condensate is collected at the bottom and is removed from the plant or will be further purified. An Independent claim is also included for a plant for purifying of unclean condensate emanated from pulp production.

Abstract: A method of processing wood oil which is generated during pulping. In the method, low molecular weight carboxyl acid that is approximately 0.5-5.0% of the wood oil quantity (weight) is added to that wood oil early in its separation stage, in order to esterify the alcohol groups present in the wood oil, by the said acid. The protective esterification according to the present invention prevents the esterification of the alcohol groups by the fatty acids naturally present in the wood oil.

Abstract: 1480863 Pneumatic tools ATLAS COPCO AB 8 Aug 1975 [8 Aug 1974] 33148/75 Heading B4C A pneumatic impact tool comprises a differential hammer piston with a head 27 and reduced shank portion 26 which slides in a constricted cylinder portion 30 thus forming a chamber 37, a further chamber 36 being formed between the piston head 27 and the tool 23 and slidable sleeve 18 surrounding it. In use chamber 37 is constantly pressurized from supply 46 and chamber 43. As the piston moves forwards holes 33 in the shank 26 allow pressure air into the shank at 31 and this passes through bore 34 to chamber 36 and an accumulator 42. Due to the differential shape of the piston it is forced backwards until holes 33 in the shank pass constriction 30 and vent the space 36 to atmosphere through outlet 40. The pressure in chamber 37 can again force the piston forwards. A cushioning spring may be provided between sleeve 18 and end cap 17 to absorb vibration. A catch 25 retains the drill steel.

Abstract: A method and an apparatus for metering a flow of a liquid, such as a milk flow in a milking system. The liquid is passed into a metering or measuring chamber from which it is discharged in portions having substantially the same mass or weight, and the total number of liquid portions discharged is counted whereafter the total mass or weight of the liquid flow may be calculated on the basis of that count. The discharge operation is controlled by a float member arranged within the metering chamber and containing a magnet which may actuate reed switches positioned at different levels along the metering chamber. Each liquid portion is discharged from the metering chamber by exposing the chamber to a gas pressure substantially exceeding the pressure at the discharge end of a metering chamber outlet. The metering chamber is preferably partly defined by a bell-shaped valve body controlling the metering chamber inlet and being movable to its closed position under the influence of said gas pressure. The apparatus may contain special means for metering a last fraction of a liquid portion as well as means for reducing formation of foam within the metering chamber.

Abstract: For cleaning hot soldering iron bits which are contaminated or soiled by tin oxides and soldering residues a flat felt or sponge has often been heretofore used. This cleaning technique is impractical, incomplete and frequently causes spatters of soldering tin or pewter at the place of work. This is unacceptable, especially when precision soldering electronic devices. This problem is solved by using an apparatus driven by an electric motor. The hot soldering iron bit or tip is momentarily placed between two cleaning bodies which rotate towards each other. These two rotating cleaning bodies thus enclose the soldering iron bit and protectively clean the same. The cleaning bodies are mounted in a removable holder or cage provided with a tin collection container or receptacle. For enhancing the self-cleaning action of the two cleaning bodies the spacing between the axes or shafts of the two cleaning bodies is smaller than the mean diameter of both cleaning bodies. Additionally, two strippers or scrapers engage into each cleaning body.
