  • Patent number: 4532036
    Abstract: A self-cleaning filtering apparatus for use in a material treating system of the type in which treating fluid is recirculated through a treating vessel. The apparatus includes a filtering chamber through which treating fluid flows from a pump to a heat exchanger. A cylindrical perforated filter element in the chamber filters particulate contaminant, such as lint in a textile processing system, onto the element, and a reciprocating cleaning member cleans the contaminant from the surface of the filter element by drawing fluid through an annular slot in a head of the cleaning member, with the fluid being drawn across and through the filter element to remove contaminant therefrom. The contaminant containing fluid is conveyed from the cleaning member back into the treating vessel where it is discharged into a large fabric bag that allows the fluid to filter through into the vessel and obstructs the contaminant for collection in the bag.

  • Patent number: 4519114
    Abstract: Apparatus and method for supplementary cleaning of cotton fibers employing a housing having an interior dividing screen separating the housing into two chambers and a fan adapted to entrain the fibers in a moving airstream and direct them into the housing against the screen for passage of the airstream and debris through the screen into one chamber and retention of the fiber in the other chamber. Reciprocably pivoting vanes divert the airstream back and forth across the screen to prevent accumulation of the fiber on the wall under the force of the airstream and to permit the fiber to fall from the wall after impact thereagainst. Alternatively, the conveying conduit may be movably mounted for side-to-side emission of the airstream into the housing. Ion emitters may be located at strategic locations to eliminate electrical attractive forces between the fibers and the debris.

  • Patent number: 4510914
    Abstract: An apparatus and method of mixing liquid fuel and air for an internal combustion engine includes an assembly providing a plurality of venturi passageways for accelerative drawing of ambient air therethrough by the vacuum created by the engine and an associated fuel supply conduit system and apertures in the venturis for aspiration of fuel into the air. One of the venturis communicates unobstructedly with the engine to provide a fuel-air mixture for idling operation and a valve arrangement effects opening and closing of at least some of the other venturis to communication with the engine responsive to increases and decreases in the vacuum. An enlarged chamber intermediate the venturis and the engine receives the fuel entrained airstream from such some venturis, reduces the velocity thereof, and thereby gravitationally separates therefrom the larger fuel droplets which will not quickly and completely combust in the engine. A recycling arrangement returns the separated droplets to the atomizing assembly.
