摘要： An improved liquid filtration system is provided which comprises, in combination, a tank or other vessel having a central cavity and a liquid inlet tube and liquid outlet tube spaced apart. A porous self-supporting filter is arched over the liquid outlet tube and forms part of the system. The filter comprises granules cemented together by organic resin. For example, fine aggregate stone particles are cemented together by an epoxy resin so that the filter is both porous and strong. Preferably, the upstream portion of the filter contains a first layer of fine aggregate while the downstream portion of the filter contains a layer of larger aggregate. The system also includes a connector releasably securing the filter over the outlet tube. The filter is relatively small, occupies only a small portion of the bottom of the tank, can be removed for cleaning and replacement and is light in weight. Preferably, the filter has an upstream cover portion of a porous metal plate material in domed configuration. The filter is inexpensive, durable and efficient. A mass of loose particles of filtering medium is disposed in the tank above the rigid filter and the tank is supported on depending legs.
摘要翻译：提供了一种改进的液体过滤系统，其组合包括具有中心空腔和间隔开的液体入口管和液体出口管的罐或其他容器。多孔自支撑过滤器在液体出口管上拱形形成系统的一部分。过滤器包括用有机树脂胶合在一起的颗粒。例如，细骨料石颗粒通过环氧树脂粘合在一起，使得过滤器既多孔又坚固。优选地，过滤器的上游部分包含第一层细骨料，而过滤器的下游部分包含较大聚集体的层。该系统还包括可释放地将过滤器固定在出口管上的连接器。过滤器相对较小，仅占据罐底部的一小部分，可以拆卸清洗和更换，重量轻。优选地，过滤器具有圆顶形状的多孔金属板材料的上游盖部分。过滤器便宜，耐用和高效。过滤介质的松散颗粒的质量被布置在刚性过滤器上方的罐中，并且罐被支撑在悬垂的腿上。

摘要： An air filter includes a hollow container with an air inlet, an air outlet, and a filter element in the container between the inlet and outlet. The filter element is made of a mass of polystyrene beads fused into a rigid block, the air passing through the interstices between the beads, which are electrostatically charged and collect the contaminants from the air. The filter element has a large number of overlapping fingerlike passages extending from the opposite sides of the filter to increase the effective filtering area for a given filter size.

摘要： There is disclosed a filtering method comprising using a filter-press-type device in the chambers whereof filtering means divide a compartment for material to be filtered from a filtrate-collecting compartment, compressing the possibly-washed material to be filtered by reducing the volume of the compartments for material to be filtered, discharging washing solute and filtrate which have passed through the filtering means, and dismantling said filter-press. The method makes use of filter means which are resistant and undistortable under the method conditions, and retains the filtering means in a relative position to the filtering chamber axis which is identical during all the filtering steps.

摘要： This invention relates to an infusion filter, in particular for use in coffee percolators, which includes a first rigid disc having an open space therein and a second rigid disc having an open space therein. The infusion filter includes a filter element having an inclined edge and a circular part having an open space therein. The filter element and the circular part are disposed between the first and second discs. The inclined edge of the filter element abuts the inclined edge of the circular part. The first and second rigid disc are molded such that the inclined edge of the filter element and the inclined edge of the circular part extend beyond the discs.

摘要： A filter has a plurality of cylindrical filter elements (5) supported exteriorly over holes (4) in a hollow filter cage (3). A backwash pipe (11) is disposed axially of the filter cage (3) and has ducts (12) which are arranged, on rotation of the backwash pipe, to register with the holes (4) in the filter cage (3) to allow backwashing of the filter elements. The filter cage (3) has retaining portions (7) in the form of a T-slot or spaced abutments. The filter elements (5) each have a circumferential flange (8) provided with at least one flat (9) so that, in a first angular orientation of a filter element (5) the filter element is held firmly by engagement of the flange (8) under the retaining portions (7) and, in a second angular orientation, it is free for removal.
