Publication number: 20110178747Abstract: A system for detecting and locating a leak through a membrane that includes a detector array and computer. The detector array includes a boundary wire loop, sensors, and leads. The boundary wire loop surrounds the area to be tested and generates electrical tension on the surface of the membrane. The sensors are laid out in a sensor array and are placed on top of a membrane and within the boundary wire loop. The sensors are encased in a plastic covered cable or individual wires which have open ends for their terminations forming a cable so that the sensors made by the open terminations form a chain. Each sensor communicates individually with the computer and the signals from the sensors are used by the computer to perform vector mapping that detects and locates leaks through the membrane.Type: ApplicationFiled: January 19, 2011Publication date: July 21, 2011Inventor: Clark Robert Gunness

The device includes a plurality of segmented modules adapted to be quickly and releasably manually affixed to a drum or like device in a manner which establishes the range of obtainable diameters of the cylindrical working surface of the existing device. No material structural and/or operational modifications in the basic elements and/or operation of the drum are required. Rather, the existing structural and operational aspects of the existing drum are employed in combination with the present invention.Type: ApplicationFiled: October 23, 2008Publication date: April 29, 2010Inventors: Sean E.

Patent number: 6390166Abstract: A rotatable drum useful in the manufacture of vehicle tires. A plurality of segments collectively define the outer circumferential surface of the drum. These segments are divided into two sets, one set being disposed on each of the opposite sides of a transverse center plane of the drum, the center plane being oriented normal to the rotational axis of the drum. The two sets of segments are mounted for selective positioning thereof axially of the drum from a location external of the drum to adjust the overall working width of the drum. Further, the segments are selectively positionable between expanded positions radially of the rotational axis of the drum to provide a relatively continuous circumferential outer surface of the drum for the layup of a tire carcass thereon, and collapsed positions radially of the drum to permit the removal of a formed toroidal carcass from the drum.Type: GrantFiled: May 19, 2000Date of Patent: May 21, 2002Assignee: WYKO, Inc.Inventors: Clark A. Roberts, Mark S. Byerley

Patent number: 5746538Abstract: A concrete barrier having a plastic cladding that provides protection for the concrete against chemical deterioration. A cap assembly enables the barrier to be fitted with standard anchor sheets and made in standard jersey barrier forms. The cap assembly has a large radius so that anchor sheets can be easily bent and will fit snugly within the form to prevent wet concrete from leaking between the anchor sheet and the form. The invention can be used with all standard jersey barrier forms, both horizontal and upside-down type, for either full or half barriers.Type: GrantFiled: October 1, 1996Date of Patent: May 5, 1998Inventor: Clark Robert Gunness

Patent number: 5240315Abstract: A sewing machine cabinet for mounting a sewing machine and for housing and storing the machine when not being worked, which provides a drop platform interiorly of the cabinet below the top working surface thereof for lowering the machine into the interior of the cabinet maintaining the sewing machine in an upright position not tilting. The cabinet is well adapted to open-arm sewing machines. A hinged top cover when opened lifts the sewing machine up out of the interior of the cabinet by leverage action on a pivoting link attached to a guided sliding support arm which is attached to drop platform which supports the sewing machine and is guided by a rack. The rack is provided by one or a pair of guide columns. The hinged top cover when opened 180.degree. acts as a brake and lock for the moving drop shelf.Type: GrantFiled: March 9, 1992Date of Patent: August 31, 1993Assignee: Roberts Mfg., Inc.Inventors: Fredrick D.
