Title: Method for softening water
Inventor: MAEDA YUSUKE
IPC: C02F1/42
Filed: 1986-11-20
Abstract: PURPOSE:To enhance softening treatment capacity, by blowing air in a resin sedimentation bed formed by removing a supernatant liquid from the lower part of a column to uniformly stir said resin bed. CONSTITUTION:The softening treatment of water is performed by passing raw water through an Na-type strong acidic cation exchange resin from the upper part thereof. After the resin is regenerated by backwashing water, the resin is allowed to sediment and water is drawn out up to the upper part of the sedimented resin bed and the resin is regenerated by brine. Before and after this regeneration, air is blown in the resin sedimentation bed to uniformly stir said resin bed. By this method, the softening treatment capacity of water can be enhanced.

IPC: B01J20/14
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To reduce the scattering of dust when bagged diatomaceous earth is charged in a precoat tank immediately after opening by using diatomaceous earth as flaky wet diatomaceous earth and making a bag member moisture- impermeable. SOLUTION: A bag member is filled with diatomaceous earth used as a precoat agent for precoat filtration. At this time, diatomaceous earth is used as flaky wet diatomaceous earth.

CONSTITUTION:Films 88-91 are rewound out of original sheets 84-87, winding them on a drive roll 78 from the underside, and they are passed through between a drive roll 106 and a pressure roll 108 of tension devices 102-105 via main rolls 94-97. And, rewinders 72-75 and these tension devices 102-105 are driven at the same time, feeding these films 88-91. In this case, since the side of these tension devices 102-105 is speedier than these rewinders 72-75, these films 88-91 come into a tensile state. When a lap A is fused while feeding these films 88-91, if strain or slack exists in this lap A, speed of these rewinders 72-75 is finely adjusted. Thus, these films are spliceable without entailing any strain or slack.

Title: Rotary shearing device for metal strip welding machine
Inventor: OTOWA YOICHI
IPC: B23D19/04
Filed: 1989-10-26
Abstract: PURPOSE: To easily replace shears, easily adjust a gap and a lap, and maintain constant cutting accuracy at all times by lifting a rotary shear device by a swing of parallel links, and regulating an ascending position of a shear frame by a stopper device. CONSTITUTION: When a rotary shear device 2 is raised by swinging parallel links 5, 6 by a driving device 7 in a cutting process of strips 29, 30, an ascending position of the shear device 2 is regulated by a preset position of a stopper receiving piece 12. Here, a height of a cutting device of shears can be changed by adjusting this position since an adjusting metal fitting 14 having the receiving piece 12 can move in the lateral direction by an adjusting screw 15. That is, when a position of shears is changed in the vertical direction due to a plate thickness change and shear abrasion, a position of the shears ascends by a dimension (b) when the receiving piece 12 is moved rightward by a screw 15, and descends by a dimension (a) when the receiving piece is moved leftward. Thus, welding of both strips and then, trimming process of the welding part are performed after cutting a plate.
