IPC: F16H25/16
Filed: 1985-04-27
Abstract: PURPOSE:To form a uniform ink film surface to a printing surface by eliminating the lateral-shaking shock of each kneading roller, by mounting a cylindrical groove cam making the central part of a kneading roller group rotatable to the outer side surface of a frame and further allowing each kneading roller to cooperate with the cylindrical groove cam through a shaking lever to freely shake the kneading roller group to the lateral direction. CONSTITUTION:A cylindrical groove cam 1 has an oblique surface like groove formed thereto and is mounted to one outer side surface of a frame so as to make the central part of a kneading roller group rotatable. A drive motor is operated to rotate the cylindrical groove cam 1 through intermediate gears 7, 8. Shaking rollers 11 are successively rotated laterally through shaking levers 10 by the rotation of the cylindrical groove cam 1. When a motor other than the drive motor of a printing press main body is used as the drive motor of said cam 1, the lateral shaking of the kneading roller 11 can be arbitrarily adjusted apart from the rotation of the main body. By this method, the acceleration at the beginning of the start of each kneading roller 11 and at the final point thereof can be brought to 0 and shock generated at the time of lateral shaking can be relieved.

Title: Method and device for contact aeration of waste water
Inventor: TSUBOKAWA TSUNEO
IPC: C02F3/06
Filed: 1981-06-17
Abstract: PURPOSE: To give repetitive circulating flow and to obtain high purification efficiency with less supply rates of air by diffusing air from the bottom surface of a part of contact filter media segmented in a contact aeration tank, and allowing the ascending flow flowing in the filter media to descend from the top surface of the other filter media.  
     CONSTITUTION: Segmented contact filter media 22A, 22B are disposed in an aeration tank 21, and an air diffuser 28 is provided below a part of the media 22A. The diffused air ascends as bubbles, and the ascending flow generated by this passes through the inside of the media 22A and arrives at the water surface. It is interrupted by a partition plate 25, goes to the opposite direction, flows into the medial 22B from the top surface and arrives at the bottom part of the media 22B. This flow is induced by the air lift effect by the air diffusion and ascends again in the media 22. By this mechanism, sufficient velocity of circulation flow is obtained with less supply rates of air. The water in the tank contacts the biomembranes of the filter media frequently at sufficient flow of velocity, by which purification efficiency is improved and the thickness of the biomembranes is decreased.
