Abstract: PURPOSE: To remove air header pipes arranged in a water channel and thereby to maximize a water flow region in the water channel by communicating each air duct block with an underdrain lateral and further by communicating adjacent air duct blocks with each other. CONSTITUTION: An apparatus for discharging and backwashing filtering media in an air/water underdrain systems of a gravity filter comprises a row of plural interconnected air duct blocks 25 arranged below the filtering media and extending transversely to the underdrain laterals. Each air duct block 25 is in communication with an adjacent underdrain filter block via a regular polyhedron 30 in order to supply backwash gas thereto, thereby supplying the backwash gas to its associated lateral. Each air duct block 25 is in further communication with adjacent air duct block 25 so that the backwash gas flows between the interconnected air duct blocks 25 and along the row of air duct blocks 25. This system supplies the backwash gas to the entire underdrain system via a single pipe from a source of gas supply.

Filed: 1981-03-13
Abstract: PURPOSE: To transfer long materials without causing any deformation including bending by a method in which feeding and idling are optionally combined during the feeding of the materials by moving a mobile beam in longwise direction during one cycle of its rotation.  
     CONSTITUTION: When main shaft 31 is turned clockwise by a motor M 1 , the rotation is transmitted through a connecting plate 34 and a drive shaft 35 to a mobile part 41 which makes a turning movement at a radius of l 3 . The turning movement of the part 41 is transmitted through rollers 43 and 44 to a mobile beam 11 to deliver long materials. In the idling, when long materials are present on a fixed beam 21, a rotary shaft 6k is turned through k80° by a motor M 2  and a pin 63 is turned through 180° through a disc 62. As a result, the pin 63 is displaced by 2l 4  sideways, whereby the beam 11 is moved by 2l 4  to make the concavities 12 and 22 of both beams 11 and 21 coincide. When the main shaft M 1  turns continuously, the materials turn while rotating in the same concavity. To return it to feeding again, the pin 63 is turned through 180° by the motor M 2 .
