    Abstract: An erosion-resistant sand screen assembly is described for use in petroleum wells of the type in which sand tends to become entrained in the stream of petroleum entering the wellbore. The assembly is especially useful in cased holes in formations which consist of very find sand, such as have been encountered in the Gulf Coast region of the United States and off the east coast of Trinidad. The assembly uses a sleeve with an erosion-resistant wall at least one-fourth inch thick, positioned around the outside layer of wire screen. Preferably, the assembly has an outer surface of a resilient elastomeric material.

    Abstract: Apparatus for removal of solids from gaseous medium by the use of a filter surface in the form of filter tubes from which the filter cake is removed by a reverse burst of high pressure gas without stopping filter flow and in which the gaseous medium with suspended solids is baffled for introduction into the filter section in a manner not to interfere with the disposal of the removed filter cake and to enhance solids separation.

    Abstract: PROBLEM TO BE SOLVED: To improve moisture separation function inside of a fuel filter.
    SOLUTION: A protector case 8 covering an upper part outer circumference of a filter element 7, existing in a lower side of a inlet port 2 and partitioning a case 4 to upper part and a lower part liquid-tightly is provided. Fuel flowing in the case 4 from the inlet port 2 passes through a filter element 7 and flows into inside of the protector case 8 after flowing to an outer circumference side from an upper end surface inner circumference side of the filter element 7 through a plurality of slits 17 formed inner circumference side of a top part of the protector case 8.
