    Abstract: A non-woven fabric web is converted to a tubular shape by forming the web between a cylindrical mandrel and surrounding sleeve, and passing reciprocating barbed needles through the region where the sides of the web abut each other, to form a butt joint thereat. The apparatus includes a pair of rollers for drawing the tubular shaped web between the mandrel and sleeve, as well as a motor and control circuit for operating the reciprocating needles.

    Abstract: A system for regenerating a system filter in a fluid flow line where the filter normally retains particulate matter entrained in the fluid flow in one direction is disclosed. The system involves a filter structure in which reverse or back flow through the filter will dislodge particulate matter from a filter element in the filter. Entrained particulate in the fluid back flow is passed to a vortex separator which separates by centrifugal forces and densities, the particulate from the fluid. The cleansed fluid is passed through a separate filter and can be returned to the system. The system for using the separator and separate filter in conjunction with the system filter can take the various forms including: (1) embodiments where an independent pump is employed and the system filter is releasably coupled with separator, the separate filter and the pump in a closed loop, and (2) embodiments where the fluid from the system is diverted by valves to reverse through the system filter and output to the system from the separate filter.

    Abstract: A filter assembly for filtering fluid returning to a reservoir including a filter housing, a base closing one end of the housing, an outlet port in the base, and a perforated fluiddiffusing member enclosing said base together with the housing in an axially stacked arrangement therewith to disperse the discharge of fluid from the outlet port in a relatively wide flow pattern in order to minimize surface turbulence and resultant aeration of the fluid within the reservoir.

    Abstract: A filter having a plurality of axially aligned and axially spaced flat annular disks of filtering material separated by inner and outer support members alternating axially with the respective disks and having radial spokes providing axial support for the central portions of the disks intermediate their peripheries and terminating in circumferentially widened portions cooperating with adjacent support members to define inlet and outlet openings communicating with the spaces between the disks for the flow of fluid axially through the disks.
