Abstract: The strength properties of chemical cellulose pulp (particularly kraft pulp) are improved by substituting a cold impregnation soak for conventional impregnation procedures. After steaming, wood chips are soaked in an alkaline liquid at a temperature of about 80-110° C. (preferably 80-100° C., or 90-105° C.) for between one-half-72 hours (typically about 2-4 hours) at a pressure of about 0-15 bar (preferably about 1-5 bar), to dissolve at least about 8% of the wood (preferably about 10-20%) and at least about 15% of the lignin. The alkaline liquid used preferably contains sulfide (e.g. black liquor, green liquor, white liquor, or mixtures thereof), but almost any alkaline liquid having an alkali concentration of about 1.0 mole of NaOH/liter or less (typically about 0.75 m/l or less) is suitable. The wood chips are then raised to a cooking temperature of about 145-180° C. and cooked to produce the cellulose chemical pulp.

Abstract: A method and apparatus for reducing a number of calculations during equalization is disclosed. A burst is processed using weak equalization and with strong equalization when a predetermined criteria is met. By performing weak equalization rather than strong equalization when a predetermined condition is met the number of calculation may be reduced for most bursts. In addition, in one embodiment of the present invention, if strong equalization fails, then turbo equalization is used. Equalizer selection for subsequent bursts in block may occur after review of the equalization results of the first burst in a block.

After steaming, wood chips are soaked in an alkaline liquid at a temperature of about 80-110° C. (preferably 80-100° C., or 90-105° C.) for between one-half-72 hours (typically about 2-4 hours) at a pressure of about 0-15 bar (preferably about 1-5 bar), to dissolve at least about 8% of the wood (preferably about 10-20%) and at least about 15% of the lignin. The alkaline liquid used preferably contains sulfide (e.g. black liquor, green liquor, white liquor, or mixtures thereof), but almost any alkaline liquid having an alkali concentration of about 1.0 mole of NaOH/liter or less (typically about 0.75 m/l or less) is suitable. The wood chips are then raised to a cooking temperature of about 145-180° C. and cooked to produce the cellulose chemical pulp.

Abstract: A method and an arrangement are presented for processing received data blocks in a digital radio receiver. Received data blocks are equalized (306) and channel decoded, (309) after which they are checked (310) for errors. Additionally there is monitored (303) the amount of received but not yet equalized and channel decoded data. As a response to a finding indicating that an equalized and channel decoded data block contains errors (310), it is checked (313) whether the amount of received but not yet equalized and channel decoded data is below a certain threshold. As a response to a finding indicating that the amount of received but not yet equalized and channel decoded data is below said threshold, the data block which was found to contain errors is iteratively equalized and channel decoded. By adaptively allowing iterative equalization and channel decoding, retransmissions may be avoided.
