Patent number: 7722762Abstract: A horizontally traveling water screen for filtering debris from a wide flowing stream. The water screen, which may be realized by a foraminous modular plastic conveyor belt, is formed in an endless loop trained between drive and idle sprockets rotatable on generally vertical shafts. The upstream face of the water screen is oriented transverse to the flow and advances horizontally across the stream to drag debris to a cleaning and discharge station. Horizontally spaced hold down tabs extending outward of the inner surface of the loop hook onto and ride along a horizontal guide attached to a support frame for the water screen to prevent the screen from sagging.Type: GrantFiled: July 22, 2005Date of Patent: May 25, 2010Assignee: Laitram, L.L.C.Inventor: Omair Zubair

Patent number: 7527145Abstract: A low-friction conveyor (10) including a conveyor belt (12) supported on self-contained rollers (32) riding along a carryway (22). The conveyor includes a modular conveyor belt constructed of a series of rows of belt modules (24, 25) connected into a loop by hinge joints between adjacent rows (26). The belt is supported on a carryway. Drive surfaces are accessible from the interior side (28) of the belt loop. Drive elements, such as sprockets (16), drive on the drive surfaces to move the belt along the carryway. The belt rollers are recessod inward of the outer side (29) of the belt loop and extend past the interior side of the belt loop. In this way, the rollers engage the carryway in low-friction, rolling contact.Type: GrantFiled: May 30, 2003Date of Patent: May 5, 2009Assignee: Laitram, L.L.C.Inventors: Omair Zubair, Gerald O'Connor, Kyle Sedlacek

Patent number: 7300572Abstract: A traveling water screen comprising an endless foraminous belt with flights. The foraminous belt forms a water screen extending from a lower end in a flowing stream to an upper end above the surface of the stream. The stream flows through openings in the foraminous screen. The flights, which may be scoops, are arranged in spaced apart relation on the outer surface of the water screen. The water screen is driven in a direction so that its upstream portion advances upward and its downstream portion downward. The flights form inclined surfaces across the width of the screen from a point of highest elevation to one or more points of lowest elevation at one or both side edges of the screen. As the screen moves, the flights lift fish toward the surface. As a flight breaks the surface, fish slide down the inclined flights toward one or both side edges of the screen to be diverted safely.Type: GrantFiled: May 23, 2006Date of Patent: November 27, 2007Assignee: Laitram, L.L.C.Inventors: Joseph M. DePaso, Omair Zubair, Kyle J. Sedlacek
