Abstract: A rail-tie fastening assembly for connecting a rail having a rail flange to a tie comprising a rail seat assembly and a rail anchor. Th rail seat assembly is connectable to the tie and includes an anchor slot and a seat hook assembly. The seat hook assembly is adapted to extend a distance over an upper surface of the rail flange. The rail anchor includes an anchor hook assembly adapted to extend over on the upper surface of the rail flange in an assembled position of the rail anchor to the rail seat assembly. The rail anchor is insertable through the anchor slot in the rail seat assembly to the assembled position. The seat hook assembly is spaced a distance from the upper surface of the rail in the assembled position of the rail anchor to the rail seat assembly. The anchor hook assembly engages one side of the rail flange and the seat hook assembly engages the opposite side of the rail flange to restrain lateral movement.

Abstract: A venting system for allowing the escape of harmful water vapors trapped in the roof system. The system includes a roof deck forming the base of the roof system, a roofing membrane positioned over the roof deck, and a channel network positioned between said roof deck and said roofing membrane to form a plurality of venting passages below said membrane. The channel network comprises a plurality of integrally formed channel members arranged to form a grid covering the roof deck. The cross section of the channels is shaped as an inverted trough, thereby providing sufficient strength to the network's surface to support the outer roof treatment and/or to permit an installer to walk across the surface of said network without collapsing it. Roof vents pierce the roofing membrane and provide a relief passage communicating with the venting passages. Water vapor trapped beneath the roofing membrane is channeled through the venting passages to the roof vents where it evaporates into the atmosphere.
