  • Apparatuses and methods for forming wireless RF labels
    Patent number: 7559486
    Abstract: Apparatuses and methods for forming wireless RF labels are claimed. In one embodiment, a flexible layer may be made to receive an array of integrated circuit chips The integrated circuit chips may be powered by a signal from a transmitter which beams the information to the wireless RF labels. The method includes coupling a plurality of integrated circuit chips to a flexible web material and advancing the flexible web material through a web processing apparatus. A metallization material is patterned on the flexible web material. The flexible web material can be coupled to a second web material.

  • Rail-tie fastening method for concrete tie
    Patent number: 5494212
    Abstract: A rail-tie fastening assembly for fastening a rail to a concrete tie comprising a rail seat assembly and a rail anchor. The rail seat assembly includes a rail seat basin and a rail seat wherein the rail seat is disposed in the rail seat basin and bonded thereto with an elastomeric material having a void formed therein between the bottom of the rail seat and the bottom of the rail seat basin so as to produce a shear spring which transfers applied vertical load from the rail to the tie. The rail seat assembly is embedded in the tie and the rail anchor is adapted to engage a portion of the rail and to interlock with the rail seat assembly so as to cooperate with the rail seat assembly to fasten the rail to the tie.
