Patent number: 7942167Abstract: An expandable pipe (20) for restoring a damaged conduit (22) includes a liner (24) formed of polypropylene material. The liner (24) presents exterior surface (26) defining a plurality of grooves (28) and surrounding a center opening (32). The grooves (28) contain a grout material (30) and provide for controlled placement of the grout material (30). The grooves (28) maintain the placement of the grout material (30) when sliding the expandable pipe (20) into the conduit (22). The grout material (30) includes urethane and recycled fibers (36), and expands in volume upon contact with moisture. The grout material (30) expands to fill cracks in the conduit (22). The grooves (28) also render the expandable pipe (20) bendable in width (W) at the groves for folding and transporting the expandable pipe (20) and for maneuvering around bends of the conduit (22).Type: GrantFiled: April 13, 2010Date of Patent: May 17, 2011Inventor: Clinton Edward Llewellyn

Patent number: 7942169Abstract: A folding type cable protection and guide device is provided in which a cable is accommodated into a cable accommodating space. The cable accomodating space can be easily adapted to accommodate the cable, even if the cable is a long body. The assembly load is decreased. Further, the use of many different sized metal molds is not required. The form stability of the cable accommodating space is sufficiently ensured during both linear movement and flexion movement, so that smooth linear movement and flexion movement can be attained. The rectangularly shaped cable accommodating space is formed by folding a pair of right and left folded sections 110, 110 extending in a longitudinal direction of the extruded synthetic resin tape 100 along the longitudinal direction of the tape.Type: GrantFiled: July 20, 2007Date of Patent: May 17, 2011Assignee: Tsubakimoto Chain Co.Inventors: Shoichiro Komiya, Takayuki Matsuda

Patent number: 7942171Abstract: An implement for mechanically filling multiple sandbags at a time is used on a loader bucket of loader-type equipment. The implement has a planar surface in which a plurality of filler apertures are formed in a plurality of rows evenly spaced over its surface area. Each filler aperture has a tensioner ring around the aperture for holding a drawstring held in a sleeve around an open end of the sandbag. A trigger mechanism is movable to a locked position in which the drawstring of the sandbag is pulled tight so that the open end of the sandbag is held in place on the tensioner ring, to an unlocked position in which the trigger mechanism lifts the drawstring off the tensioner ring to allow the sandbag filled with filler material to pull on and cinch the open end of the sandbag closed, and to a release position in which the cinched sandbag is released to the ground.Type: GrantFiled: July 9, 2009Date of Patent: May 17, 2011Assignee: Barrier Systems, LLCInventor: Joseph W. Hartley, III

Patent number: 7942172Abstract: A bottle refilling device that allows an individual to fill a number of bottles at the same time, with the number of bottles preferably being between 12 to 24 bottles. The device has the shape of a flat panel and has an inlet on the top surface of the flat panel to which a funnel can be attached. A series of disbursement nipples are attached to the bottom surface of the flat panel, to which a number of containers can be attached. Each of the containers can be attached to a particular nipple through engagement with a two-part clamp associated with each nipple. A locking slide system is attached to each of the clamps, allowing the clamps to remain in either a closed position or an open position.Type: GrantFiled: July 17, 2008Date of Patent: May 17, 2011Inventor: Saul E.
