    Abstract: An aluminum clad multiplex superconductor comprises an aluminum alloy cladding and a multiplex superconductor inserted into the cladding and is constructed with a plurality of unit superconductors twisted or braided with each other, each of which unit superconductors is constructed with a strand of a plurality of superconductive wires, an intermediate aluminum layer and a relatively hard aluminum alloy layer surrounding the intermediate layer. The intermediate aluminum layer serves to prevent the flowing phenomenon during the withdrawing of the unit superconductor.

    Abstract: THE PH OF SULFITE SPENT LIQUOR TO BE TREATED IS FIRST ADJUSTED TO NEUTRALITY OR WEAK ACIDITY. TO THE RESULTING LIQUOR IS ADDED A WATER-MISCIBLE ORGANIC SOLVENT HAVING A SOLUBILITY PARAMETER VALUE OF 9.0 TO 12.5 IN AN AMOUNT SUCH THAT THE WEIGHT RATIO OF THE SOLVENT TO WATER PRESENT IN THE SPENT LIQUOR WILL FALL IN THE RANGE OF FROM 6:4 TO 4:6 THUS CAUSING HEMICELLULOSES TO BE PRECIPITATED FIRST. THE HEMICELLULOSES ARE REMOVED FROM THE LIQUOR. THEN, THE ORGANIC SOLVENT IS ADDED AGAIN TO THE RESIDUAL LIQUOR AFTER THE REMOVAL OF HEMICELLULOSES SO AS TO CAUSE FORMATION OF A HEAVY LIQUID PHASE CONTAINING LIGNOSULFONATES AND A LIGHT LIQUID PHASE CNTAINING MONOSACCHARIDES. THE TWO PHASES THUS FORMED ARE SEPARATED AND REFINED TO PRODUCE LIGNOSULFONATES AND MONOSACCHARIDES. THE ORGANIC SOLVENT USED IN THE PRESENT TRETMENT IS RECOVERED FROM THE LIGHT LIQUID PHASE.

    Abstract: In a vacuum vessel, a pipe and a bar which have the same outside diameter and are made of the same material are disposed parallelly to each other, with the ends thereof fixedly fastened to the side walls of the vessel. Said pipe and bar are provided with vibrating means which cause the pipe and the bar to vibrate. The pipe is first vibrated when the pipe interior is devoid of matter. The inside diameter of the pipe is determined indirectly from the consequent frequencies of the pipe and the bar. The pipe is then filled with a fluid whose density is to be determined and it is thereafter vibrated. The absolute density of the fluid contained in the pipe is directly determined with high accuracy on the basis of the frequency of the pipe in the packed state and the former frequency of the pipe in the empty state.

    Abstract: Sulfite pulp cooking liquor is produced from sulfite pulp spent liquor by combusting condensed sodium-based spent liquor in an oxidizing atmosphere, adding lime to and blowing sulfur dioxide gas into an aqueous solution of the ash so obtained as to produce an aqueous solution of sodium bisulfite containing calcium sulfate and separating out the calcium sulfate. Alternately, the condensed spent liquor is combusted in a reducing atmosphere, sulfuric acid is added to the resultant smelt to produce an acid solution to which lime is added and into which sulfur dioxide gas is blown and the calcium sulfate produced is separated.

    Abstract: A twisted yarn is spun by pressing a strand of fibers against a rapidly rotating roller to separate the fibers, pressing the separated fibers against the wall of a main rotary drum, allowing the fibers pressed against the drum wall to be moved in the direction of a fiber condensing portion of the drum, and causing the fibers at this drum portion to be twisted and intertwined with the end of a preceding yarn portion spun in this manner.
