摘要： A method of filtering and a filter having a housing in which a filtering screen having a bag-shaped configuration is located. A removable floatable container is located within the filter housing, inside the filter screen. The container includes parts which are spacedly positioned from the screen so as to enable liquid flow through the filter to pass around the container and through portions of the screen.

摘要： A method and apparatus for filtering a material that flows through a filter housing having a housing chamber, a material inlet port, a material outlet port, and an annular shoulder disposed in the housing chamber. A non-sealing filter element having a fluid pervious filter bag fixed to a non-sealing shape retaining filter collar assembly including an annular sleeve, an outturned annular flange, and a fluid pervious annular filter element disposed on the annular shoulder of the housing chamber. The fluid pervious annular filter element may be a separate element interposing the outturned annular flange of the non-sealing shape retaining filter collar assembly and the annular shoulder of the filter housing to filter material not filtered by the fluid pervious filter bag. Alternatively, the outturned annular flange and the annular sleeve of the non-sealing shape retaining filter collar assembly may be comprised of a fluid pervious material to filter material not filtered by the fluid pervious filter bag.
摘要翻译： 一种用于过滤流过具有容纳室，材料入口，材料出口和设置在容纳室中的环形肩部的过滤器壳体的材料的方法和装置。 一种非密封过滤元件，其具有固定到非密封形状的非密封形状的过滤器滤芯，该过滤器套环组件包括环形套筒，出口的环形凸缘以及设置在容纳室的环形肩部上的流体可透过的环形过滤元件。 流体可透过的环形过滤器元件可以是插入非密封形状保持过滤器套环组件的翻转的环形凸缘和过滤器壳体的环形肩部的单独元件，以过滤未被流体透过过滤袋过滤的材料。 或者，推出的环形凸缘和非密封形状保持过滤器套环组件的环形套筒可以由流体可透过的材料组成，以过滤未被流体可透过滤袋过滤的材料。

摘要： An extension kit for adaptation to an existing filter housing provides a two-fold increase in filtering surface area, while inducing a vibration into a resultant filter housing structure which resultantly loosens entrapped impurities to extend the life and frequency between filter change-outs.
