The rigid support section may include a flange and the strain relief zone may extend around the rigid support section to encapsulate the flange in addition to providing additional support to the screen cloth. The rigid support section and the strain relief zone may be co-formed in a molding process. Alternatively the rigid support section may be a molded member and the strain relief zone may be an extrusion to be assembled to the rigid support member. The screen cloth is affixed to the peripheral frame.Type: GrantFiled: May 13, 2005Date of Patent: July 31, 2007Assignee: M-I L.L.C.Inventors: Eric Cady, Brian Carr

Patent number: 7090083Abstract: A module is provided for screening or diverting particulate material. A method for producing a module for screening or diverting particulate material is also provided. Each module comprises either a screening member having an array of sieve apertures of a predetermined size defined therein for allowing particulate material up to the predetermined size to pass through the module or a diverting member or redirecting the flow path of the particulate material. A plurality of posts removably and interlockingly supports at least one reinforcing support frame and at least one module. Each reinforcing support frame is interlockably mounted onto the posts, and is readily detachable therefrom. Each module is disposed on the interlocking posts and is mounted onto, and readily detachable from, the reinforcing support frame. Each module is further positioned on the frame such that any particulate material passing through the module passes through the frame.Type: GrantFiled: October 2, 2003Date of Patent: August 15, 2006Assignee: Western Wire Works, Inc.Inventors: Lynn A. Russell, Terry R. Askew, Jack Coleman Gold
