20020153671, Oct 24, 2002

Filed:

Apr 18, 2001

Appl. No.:

09/837003

Inventors:

Ronald Raymond - Chagrin Falls OH, US
William Andrick - Uniontown OH, US

Assignee:

Construction Polymers Company

International Classification:

F16L017/06

US Classification:

277/608000

Abstract:

A sealing member having an elongate body formed of an elastomeric material has a generally planar sealing surface adapted to provide an outward sealing force in a direction generally perpendicular to the sealing surface. The seal further includes a plurality of longitudinally extending hollow regions formed within the sealing member which are bounded at least in part by longitudinally extending and transversely spaced apart structural partitions. A layer of elastomeric material on a side opposite the sealing surface spans the structural partitions thus enclosing the hollow regions. The seals are useful in constructing segmented tunnels, ducts, and the like, and are particularly adapted to withstand high pressures.

International Classification:

E04C 134

US Classification:

52468

Abstract:

A resilient, pressure-locking filler strip is provided for closing a gap or joint of a wall panel assembly. The filler strip has a flange portion for enclosing the gap and a pressure-locking clip for compressive retention in the gap. The clip is selectively cooperable with the flange portion for ready interchange of a plurality of different size clips for retention in a plurality of different size gaps. The clip includes first and second opposed gripping portions for compressive engagement to associated side wall portions of the gap. In one embodiment the flange portion comprises a first flange and a second flange depending normally away from the first flange for enclosing a gap or joint at a wall corner. In another embodiment the flange portion comprises a first flange and a second flange coplanar with the first flange for enclosing a gap in a flat wall section of the wall assembly. Preferably, the pressure-locking filler strip is a plastic extrusion.

Abstract:

An embedded track construction for a transit railway including first and second parallel, spaced rails extending an indefinite length in a first longitudinal direction. A composite insert assembly extends along the indefinite length of the rails to electrically insulate the track rails from the surrounding ground surface. The composite insert also provides a positive water seal and allows lateral movement of the rail. The inserts include a first generally rigid channel and an elastomeric member received thereon. The rigid channel preferably defines an inverted, generally U-shaped configuration in which one leg is interposed between the top and bottom flanges of the rails. A second leg abuttingly engages conventional support ties that are perpendicularly disposed to the transit rails. Gauge side inserts include a cut-out formed in the elastomeric member to receive an associated wheel flange. The inserts facilitate crossing of the railway in a transverse direction, as well as travel in the longitudinal direction by emergency vehicles or the like.
