    Abstract: A pulper for pulping a fiber suspension includes a vessel, an extraction plate assembly and a rotor. The extraction plate assembly is disposed within the vessel and includes a metal plate with a plurality of holes extending therethrough. A plurality of metal inserts are respectively disposed within the holes and project from the plate. Each insert is removably attached to the plate. A rotor is disposed within the vessel adjacent to the extraction plate assembly. The inserts are removably attached to the plate by brazing the inserts within the holes, or slightly shrinking the inserts using liquid nitrogen and placing the inserts in the holes.

    Abstract: The present invention is a dual-stage, gravity continuously-backwashed filtering system for filtering contaminants from wastewater. This filtering system has a first sand-filter unit that is loaded with wastewater influent. The filtering sytem has injection points for coagulation chemicals and disinfection chemicals. The first sand-filter unit is connected in series to a second sand-filter unit of similar design. The first sand-filter unit is made up of large-grained sand, the second sand-filter unit fine-grained sand. The second sand-filter unit receives its influent from the effluent weir of the first sand-filter unit. The reject water from the second filter unit is re-introduced into the influent that is fed to the first filter unit. The reject matter from the first filter unit is passed to waste.

    Abstract: This invention pertains to a filter in general and particularly to a filter for use in filtering hydraulic oil circulating in a hydraulic system provided for a hydraulic machine. The filter is formed in a loop and includes at least two filtering materials having different filtration porosities. Those filtering materials are arranged in the circumferential direction of the loop. Since filtering materials are arranged in the circumferential direction, the filter can be manufactured at the same size as the existing filters so that it can be accommodated in the existing filter cases. Also, since the filter has more than one filtration accuracies, it is capable of catching impurities of various sizes. In operation, most of the liquid to be filtered tends to pass through the less fine filtration martial. Thus, the filter creates a small pressure loss.

    Abstract translation: 本发明一般涉及一种过滤器，特别涉及用于过滤在设置在液压机器上的液压系统中循环的液压油的过滤器。 过滤器形成环路并且包括具有不同过滤孔隙率的至少两种过滤材料。 这些过滤材料沿环的圆周方向排列。 由于过滤材料沿圆周方向布置，所以可以将过滤器制造成与现有过滤器相同的尺寸，使得可以将其容纳在现有的过滤器壳体中。 此外，由于过滤器具有多于一个的过滤精度，因此能够捕获各种尺寸的杂质。 在操作中，要被过滤的大部分液体倾向于通过较少的过滤器。 因此，过滤器产生小的压力损失。
