  • Patent number: 10765973
    Abstract: In one example, a filter core includes a body with a generally cylindrical shape and a substantially hollow interior. The body includes a first annular wall disposed proximate a first end of the body, and a second annular wall disposed proximate a second end of the body such that the second annular wall is axially spaced apart from the first annular wall, and the second annular wall and the first annular wall extend toward each other. As well, the filter core includes a framework connected to the first annular wall and the second annular wall. The framework and the first and second annular walls cooperate with each other to define a group of openings, each of which communicates with the substantially hollow interior of the body, and the openings collectively define an open space of the filter core.

  • Patent number: 10691022
    Abstract: Provided are a processing method and a processing apparatus in which a concentration of a solid content of a development fatigue liquid is low and a moisture content of a discharged solid substance is small. The processing method is a method for removing a first solid substance having a smaller specific gravity than the washout liquid and a second solid substance having a larger specific gravity than the washout liquid from a development fatigue liquid including a solid substance generated by removal of a non-exposed portion of a photosensitive resin plate that has been exposed in an image shape by development using the washout liquid.

  • Patent number: 10682594
    Abstract: A filter element for filtering fluid has a filter medium surrounding an inner cavity extending axially in the filter element. An axially extending sealing connecting piece is arranged at an axial end of the filter element. The sealing connecting piece has an opening fluidically connecting the inner cavity to a fluid channel of a filter housing and also has a seal holder structure. A double concentric seal is arranged at the sealing connecting piece and closes a drainage channel of the filter housing. The double concentric seal has radially inner and radially outer sealing elements. One of the sealing elements has an elastically deformable sealing lip that extends away from the sealing connecting piece radially and axially toward the filter medium and can be pressed against a sidewall of the drainage channel of the filter housing. The other sealing element is an oil seal arranged in the seal holder structure.

  • Patent number: 10661204
    Abstract: A method of sealing a filter bag at the stitched joints of the filtration material, consisting in forming the filter bag out of at least one filtration material piece, whereupon the surface of at least one filtration material edge being joined is covered with a liquid or semi-liquid layer of a sealant in such a way that the filtration material edges being joined are in contact with one another at least on the surface covered with the sealant. After the sealant layer has been applied, the filter bag elements prepared beforehand are combined together permanently by sewing them with a thread. A filter bag formed of at least one filtration material piece whose edges (2) and (3) are joined together with a thread (5), with at least one stitch, is characterised by the fact that at the stitched places between the adjoining surfaces of the filtration material edges (2) and (3) being combined there is a sealant layer (4), applied before sewing.
