  • Patent number: 4436190
    Abstract: A drum-type apparatus for feeding and retrieving electrical signal cable, having an intermediary reel and cable arrangement for preventing torsional cable stresses anywhere between the drum and the output circuitry. The reel is coaxially mounted with the drum, and rotates simultaneously therewith. A ribbon cable is coiled in layers around the reel, and has one end connected to the tail end of the signal cable such that the connection rotates in unison with the drum and reel. Preferably, a housing is provided around the reel to maintain the concentricity of the ribbon cable layers. As the drum rotates, the average effective diameter of the ribbon cable coil changes without causing torsional stresses.

  • Patent number: 4432271
    Abstract: A locomotion unit is remotely controlled to advance stepwise through a passageway by frictional engagement with the surfaces of the passageway walls. A support section is mounted on the locomotion device to bring special tools to bear at predetermined positions within the passageway to which the support is brought by the locomotion unit.

  • Patent number: 4368644
    Abstract: A tool for manipulating an ultrasonic inspection transducer is actuated to move the transducer over the surface of an irregular weld body. The weld body disclosed, joins the nozzle of a reactor vessel to its vessel, the irregularity of the weld body defined by the intersection of the two cylinders. The transducer is moved over the surface of the weld body and actuated to scan through a predetermined angle in relation to the changing aspect of the geometry of the weld body by a cam mounted at the pivoting center of the tool.
