Abstract: A filter employed for the extraction of beverages is formed of a piece of material having two planar surfaces and a plurality of uniformly distributed openings extending through the piece. A plurality of nipples, equal in number to the number of openings, project from and out of at least one of the planar surfaces and extend for a distance substantially equal to the thickness between the planar surfaces of the piece of material, each nipple being associated with one of the openings through the piece of material, and each opening extends through each nipple. The openings have a shape of a truncated cone, a truncated pyramid, or a truncated tetrahedron, and each opening at the end of each nipple, which is disposed away from the planar surface from which the nipple projects, forms a minor base of the opening shape and each opening at the other planar surface forms a major base of the opening shape.

Abstract: A drainage system for expressing liquids and fluids from fibrous materials. The system includes a plurality of spaced apart compression elements each retained in juxaposition one to another so as to have a fluid escape slot between each adjacent compression element. Each compression element has a longitudinal passageway therethrough each having an inlet and an outlet which is inwardly tapered toward its outlet. The combination of passageways through each compression element forms a compression conduit whose inlet and outlet generally functionally coincide with the intake and exit, respectively, of the drainage system. The fibrous material to be expressed is introduced into the system's intake under pressure, the fibrous material being compressed as it is forcably urged through each tapered passageway, the expressed fluids exiting the compression conduit radially outwardly through fluid escape slots. The slots, which may be dynamically variable in width, are sized to facilitate fluid escape or discharge, but to contain the fibrous material within the compression conduit. The preferred embodiment of the shape of each taper is a truncated cone whose nominal diameter may also vary along the length of the compression conduit to prevent build-up and cloging of the fibrous material as it passes through the drainage system. This concept of fluid discharge slot variability during operation is also applied to improvements in conventional screw press cage screen bars.
Abstract translation: 用于从纤维材料表达液体和流体的排水系统。 该系统包括多个间隔开的压缩元件，每个压缩元件彼此并置地保持彼此并排，以便在每个相邻的压缩元件之间具有流体逸出槽。 每个压缩元件具有穿过其中的纵向通道，每个具有入口和朝向其出口向内逐渐变细的出口。 通过每个压缩元件的通道的组合形成压缩导管，其压力管道的入口和出口通常在功能上与排水系统的进出口重合。 要被表达的纤维材料在压力下被引入系统的入口中，纤维材料被压缩，因为它被可塑性地推压通过每个锥形通道，表达的流体通过流体逸出槽径向向外排出压缩导管。 可以在宽度上动态变化的狭槽的尺寸被设计成便于流体逸出或排出，但是在压缩管道内容纳纤维材料。 每个锥形的形状的优选实施例是截头圆锥体，其标称直径也可以沿着压缩管道的长度变化，以防止纤维材料在通过排水系统时的积聚和堵塞。 这种在操作过程中流体排放槽变化的概念也适用于常规螺杆压网笼筛网的改进。

Abstract: The invention relates to a sieve for a paper pulp scrubber or similar equipment, and to a method for fabricating such a sieve. The sieve is produced by mechanical interfit of bars with support members, the bars carrying notches, the lips of which engage at least one V-shaped lateral groove formed in each support member, while the support members present, on their face receiving the bars, a first set of notches for positioning the bars. The cross-section of the support members at the level of the first notches has the same configuration and dimensions as the cross-section of the second notches and the cross-section of bars at the level of notches has the same configuration as the cross-section of notches formed in the support members. Assembling is made by bending a bar by an angle of about 20-25.degree. for widening a second notch and inserting a support member therein. The bar is then straightened back, so that the support member will be firmly clamped in the notch.

Abstract: An apparatus for screening pulp comprises a vessel, a cylindrical screen within the vessel, a rotating element moving in the vicinity of the screen at a predetermined speed, an inlet for the unscreened pulp, an outlet for the screened pulp in the vessel. The rotating element has a contour surface, for instance grooves formed of a first bottom plane parallel to the envelope surface, an inclined plane, an upper plane and a side plane, the side plane being essentially perpendicular to the first bottom plane, the inclined plane forming an angle between 5 degrees-60 degrees with the first plane, the upper plane being parallel to the first plane. The rotating element may be a rotor or blade type segments. The rotor is located on the inlet side of the screen but the contour surface of the screen may be the outer or the inner surface of the screen drum. Also the screen has a contour surface which may have different configurations.

Abstract: A screen plate with grooves is described. The grooves are provided at the bottom with perforations. The direction of the grooves substantially deviates from the flow direction of the pulp to be screened. By different inclination of the side planes of the grooves the turbulance force on the pulp can be varied to meet the different needs of various screening applications.
