  • Patent number: 8141442
    Abstract: A pipe scanner for non-destructively scanning an extended length of the circumference of a pipe along an axial dimension. The pipe scanner includes a collar sized to fit around the outer circumference of the pipe. Wheels supported on the collar ride on the surface of the pipe while maintaining a space between the inner surface of the collar and the outer surface of the pipe. A track extends circumferentially around the collar for guiding a circumferential drive unit that rides on the track and carries a non-destructive sensor for monitoring the surface of the pipe as the circumferential drive unit moves around the track. An axial drive unit is connected to the collar, having a plurality of circumferentially spaced drive wheels in contact with the pipe for moving the collar along the extended length.

  • Patent number: 8061208
    Abstract: A non-destructive examination pipe scanner that employs a main carriage on which a sensor is mounted, a tensioner carriage and an idler carriage. The main carriage and the tensioner carriage are positioned around the pipe at spaced locations and connected on either side by a spring band. The idler carriage is slidably supported by the spring band in between the main carriage and the tensioner carriage. The sensor on the main carriage collects data about a circumferential weld on the pipe as the main carriage drives the tensioner carriage and the idler carriage around the circumference. The tensioner carriage has a variable length connection that adjusts the tension on the spring band to urge the main carriage, idler carriage and tensioner carriage into contact with the surface of the pipe.

  • Patent number: 5974835
    Abstract: An I.S. machine has a plurality of individual sections each having a blank station for forming a parison from a gob of molten glass in opposed pairs of blankmold halves supported by opposed mold carriers displaceable between retracted and advanced positions and a blow station for forming a parison into a bottle in opposed pairs of blowmold halves supported by opposed mold carriers displaceable between retracted and advanced positions. The drive assemblies for the four mold carriers are identical having the same transmission for converting a rotary input into a linear output, and motor having a rotary output connected to the rotary input of the transmission.
