Filed: 1990-02-27
Abstract: PURPOSE:To increase the traverse speed at both end parts of a traverse without reducing the radius of curvature at a cam groove turning back part by forming a guide groove at the cam groove turning back part for inclining a yarn guide outward in the traverse direction. CONSTITUTION:A yarn guide 9 is connected to a traverse shoe 7 through a plate spring 11 to be freely inclined. An endless spiral cam groove 4 engraved in a traverse drum 5 is a double groove consisting of a lower cam groove 4a engaged with the shoe 7, and an upper cam groove 4b engaged with a yarn guide 9. The cam groove 4b is formed eccentrically to left in relation to the cam groove 4a on a left side turning back part 10a of the cam groove 4, while it is formed reversely on a right side turning back part 10b. The quantity of eccentricity is set to be the maximum at the turning back parts 10a, 10b. The yarn guide 9 is thus inclined outward as it gets closer to the turning back part, so the radius of curvature of yarn 8 becomes small without reducing the radius of curvature of the groove 4 at the turning back part, thereby the traverse speed at the turning back part can be increased.

Abstract: PURPOSE: To reduce the scale of aeration facilities and to simplify mechanical equipment by feeding air by a fan into an internal space from the aperture of a hermetic structure and effecting contact aeration with the particulate surfaces of the sewage sprayed from spray nozzles. CONSTITUTION: The spray nozzles 10 are installed at the piping in a structure 1 and the sewage is sprayed in a particulate form into the structure 1. On the other hand, the fan 12 is installed in the inlet in the aperture of the structure 1 to feed the air into the structure and to aerate the particulates of the sprayed sewage by bringing the air into contact therewith. Any kinds of spray nozzles are usable for such spray nozzles 10 and a fountain type is equally well. A fan for blasting the air from other places is usable for the fan 12 and the number of the fans to be used may be made into a plurality to deal with the large quantity of blasting.  As a result, the sprayed particles of the sewage come into direct contact with the air and, therefore, the points where the aeration is not possible do not exist and the aeration efficiency is high, unlike from the stirring and mixing system in the sewage. A biological film purification treatment is possible as well if carriers, such as pebbles, are arranged on the floor of the structure 1.
