Ontology-Based Integration of Sensor Web Services in Disaster Management

A screw feed belt is used to hold a plurality of screws and includes an elongated strap, a plurality of positioning rings, and a plurality of connecting ribs. The strap is made of a flexible material and is formed with a plurality of spaced-apart and aligned openings, each of which is defined by an annular confining wall. The positioning rings are disposed respectively in the openings. Each of the positioning rings has an inner periphery that defines a positioning hole adapted to permit extension of the shank portion of one of the screws and that is adapted to be in frictional contact with the shank portion, and an outer periphery surrounded by and spaced-apart from the confining wall of the respective opening. The positioning hole has a size smaller than the head portion of the screws so that the positioning ring is adapted to permit the head portion to rest thereon when the screw extends through the positioning hole. The connecting ribs extend radially and integrally between the outer periphery of a respective positioning ring and the confining wall of a corresponding opening. The connecting ribs are breakable to permit the respective positioning ring and the screw that extends through the respective positioning ring to separate from the strap when the screw is rotated axially by a screw driving machine.
