IPC: C07C45/00
Filed: 1985-08-14
Abstract: PURPOSE:To produce formalin almost free from metallic ion and reusable as a refrigerant, etc., from formalin contaminated with metallic ions such as iron ion, with simple procedure, by controlling the crude formalin to a specific pH, adding a coagulant thereto, and separating the precipitate by filtration. CONSTITUTION:Formalin contaminated with coloring metallic ions such as iron ion, etc., is added with the hydroxide or carbonate of preferably an alkali metal, especially sodium hydroxide to adjust the pH of the formalin to 7.5-9.0 and precipitate the above metallic ions as hydroxides. The treated formalin is further added with >=0.8ppm, usually 1.0-1.5ppm of a coagulant based on the formalin to effect the coagulation of the metal hydroxide such as iron hydroxide which is difficult to separate by filtration. Clear formalin almost free from metallic ions and usable as a raw meterial of urea resin, etc., can be produced from the above crude formalin which has been hitherto difficult to be, and, economically by a simple procedure without loss of the formalin.

Title: Method for removing defective yarn in picking
Inventor: AZUMA SATOSHI
IPC: D03D51/00
Filed: 1992-06-12
Abstract: PURPOSE:To carry out the proper removing operation by sensing whether weft yarn is pulled through a yarn guide or not in the initial stage for pulling the loopy weft yarn inserted into a shed to the side of the yarn feed in removing defective picking yarn. CONSTITUTION:In an air jet loom, defective picking occurs and a loom is stopped. The loom is then reversely rotated to pick the end of defective weft yarn (1a) in its state connected to weft yarn 1 in a main nozzle. The weft yarn 1, unwound from a length measuring and storing device and having a length required for the treatment is then inserted into a warp yarn shed in the folded back form of a hair pin by the jetting action of the nozzle. A pin- shaped weft yarn guide 20 equipped with an optical type or a pressure type yarn sensor 36 is subsequently admitted into the loop and the loopy weft yarn is then pulled to the side of the yarn feed. In its initial stage, whether the defective yarn (1a) is pulled through the yarn guide 20 or not is sensed from the presence of a yarn signal from the yarn sensor 20. The removing operation is properly set according to the sensing.
