Abstract: A scraper adjustment mechanism and method for a filter that permits an operator to adjust the distance between the scraper and a filter surface without the need to have access to the filter/scraper interface, or fasteners within the filter.

Abstract: A self-cleaning water filter, coupled to a water flow having particulates therein, that includes a pair of canisters, each having a cylindrical wedge wire water filter screen. An elongated brush running the length of the screen is disposed between two confining walls also running the length of the screen to form a chamber. A elongated partition, including two sets of apertures, is used, along with the elongated brush, to divide the chamber into two particulate dislodge chambers and a drain subchamber. A drain is in fluid communication with the drain subchamber. During cleaning, the drain is opened and the screen is rotated against the brush for liberating the particulate contaminants and a limited amount of the water flow into the two dislodge subchambers. The particulate contaminants and the limited amount of water then pass through the apertures at a high velocity and into the drain subchamber which exits through the drain.

Abstract: A self-cleaning fuel oil strainer, coupled to a continuous fuel flow, that includes a pair of canisters, each having a cylindrical wedge wire fuel oil filter screen. An elongated brush running the length of the screen is disposed between two confining walls also running the length of the screen to form a chamber. A elongated partition, including two sets of apertures, is used, along with the elongated brush, to divide the chamber into two particulate dislodge chambers and a drain subchamber.

Abstract: A method for reducing the amount of cleaned water required in cleaning a particulate strainer using a reverse flow system is disclosed herein. The method includes the steps of: disposing a stationary cylindrical strainer in a first fluid flow to capture particulates against a first upstream surface of the strainer; positioning a single self-contained ultrasonic energy source within an inner region of the stationary cylindrical strainer defined by a downstream second surface the second surface permitting passage of a cleaned fluid flow; stopping the first flow; activating the ultrasonic energy source to dislodge particulates from the first surface; sending a reverse flow of the cleaned fluid flow through the second surface and through the first surface to evacuate the dislodged particulates from returning to the first surface; and restoring the passage of the first flow through the strainer.

Abstract: A locker door and frame assembly including a one-piece locker door having integral box beam supports at the extreme side edges of a central rectangular panel of the door and including hinge means directly connected to one marginal area of one of the integral box beam supports and to an adjacent side frame member of the frame for pivotally connecting the locker door to the frame through one of the integral box beam supports. A single-point latch system is located adjacent the side edge of the door remote from the hinge side for use in locking the door to the frame at only a single point spaced intermediate the opposed end edges of the door. The box beam supports can be of a number of different cross-sections, and most preferably the box beam support adjacent the hinge side of the door is wider than the box beam support adjacent the latch side of the door.
