Abstract: An apparatus for purifying waste liquids which includes (a) a mixing chamber for introducing and mixing a pressurized gasliquid phase, which substantially saturatedly dissolves a pressurized air into a waste liquid under the pressure, (b) a curved liquid chamber having a flat circular arcuate or curved spiral for separating the waste liquid into substances to be removed, such as flocs, etc., and a liquid, and (c) a scum outlet duct so disposed as to communicate with the curved liquid chamber at the upper portion of the chamber for discharging a scum of the substances to be removed floating on the surface of the liquid in the curved liquid chamber. The mixing chamber and the curved liquid chamber are separated from each other with partitions, but one of the partitions has an opening at the upper portion thereof so as to communicate the mixing chamber with the curved liquid chamber.

Abstract: A method of supplying weft yarns includes the steps of holding the free end of a predetermined length of yarn to be used for a weft yarn by suction and a portion of its length near the end along a fluid flow path and supplying the held yarn into the shed by means of a yarn carrier which grips the yarn end and traverses the shed. The apparatus for accomplishing the method includes a reserve pipe into which a predetermined length of yarn is placed from a supply and held for insertion into the shed and a fluid ejector to feed the free end of the yarn to a suction holding device across the path of the weft yarn carrier. The carrier is provided with a gripper for holding the free end of the weft yarn as the carrier is flown across the shed with the ejector assisting in the weft yarn feed.
