    Abstract: A maintenance screen for use in low-velocity, shallow or horizontal or slightly inclined wells is disclosed. The maintenance screen of the present invention utilizes a generally downwardly oriented portion through which fluid can pass and a generally upwardly oriented portion which does not allow sand or fluid to pass therethrough, so that sand naturally gravitates downward through the fluid and away from the portion of the screen through which the fluid may pass to enter the well tubing.

    Abstract: A wall means intended for apparatus for separation of a liquid-containing portion from a liquid-containing particle material which is fed through the apparatus in a predetermined direction (A). The wall means comprises a plurality of bar profiles defining continuous slots between them to allow through the liquid-containing portion. According to the invention each bar profile has on its inner side facing the liquid-containing particle material a ridge portion extending between the ends of the bar profile and being provided with two continuous guide surfaces which, as seen in a cross section of the rod profile, are inclined in relation to the drainage direction (B) of the liquid-containing portion through the adjacent slot. Furthermore, the inclined guide surfaces in their longitudinal direction are disposed to coincide with the predetermined direction of feed (A) of the liquid-containing particle material in order to influence the liquid-containing particle material to maintain this direction of feed (A).

    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 PRESENT INVENTION RELATES TO FILTERS, FOR EXAMPLE DISC TYPE FILTERS USEFUL IN THE PRODUCTION OF POLYMERS. MORE PARTICULARLY, IT RELATES TO DISC TYPE FILTER CORES WHICH SERVE AT LEAST TWO FUNCTIONS, (1) ADDING SUPPORT TO THE FILTER MEDIA, AND (2) PROVIDING CONTINUOUS FILTRATE FLOW PASSAGES DURING THE FILTERING PROCESS ATTENDANT TO SUCH PRODUCTION. EACH FILTER CORE COMPRISES AT LEAST TWO DISCS IN FACE-TO-FACE RELATION, AT LEAST ONE OF THE DISCS HAVING ELONGATED APERTURES THEREIN AND AT LEAST ONE OF OTHER DISC HAVING AT LEAST ONE ELONGATED FILTRATE CONDUIT MEANS

    THEREIN. THE APERTURES AND THE FILTRATE CONDUIT MEANS COOPERATIVELY FORM A CONTINUOUS FLUID PASSAGE SUCH THAT, FOR EXAMPLE, FOR A GIVEN FILTRATE FLOW VELOCITY, FILTER MEDIA SUPPORT MAY BE MAXIMIZED.
