Patent number: 4389611Abstract: An apparatus for sending a sensor, such as an eddy current sensor, into a condenser, heat exchanger or steam generator tube. The apparatus first sends the sensor, which is attached to a cable, into the tube by means of a pressurized fluid which pushes the sensor along tube interior. At the extreme of the sensor's travel into the tube, a first ferrule attached to the rear of the cable blocks a first hydraulic passage in the apparatus. By virtue of slidable control pistons in the apparatus, this blocking cuts off the pushing pressure behind the sensor and then causes wheels to frictionally engage the cable to pull the sensor back to its starting position. At this time, another ferrule, carried near the sensor end of the cable, blocks a second hydraulic passage to thereby disengage the wheels from the cable. The cycle of (1) sensor pushed into the tube (2) sensor withdrawn from the tube, is now complete.Type: GrantFiled: September 25, 1980Date of Patent: June 21, 1983Assignee: Commissariate a l'Energie AtomiqueInventors: Michel Pigeon, Claude Vienot, Robert Saglio

Patent number: 3948425Abstract: A web handling mechanism is described for incrementally feeding a web of stretchable material (e.g., plastic film) to a processing station. The web feed rollers are driven by a motor incorporated in a servo system which electronically controls the feed rate, length of increment, dwell at processing station, etc. Variations in the speed and elasticity of a moving web are accommodated by means of a vacuum box adapted to accumulate a loop of the web material in the box and maintain proper tension on the web as supplied to the feed rollers. A detector in the vacuum box responds to a predetermined length of web accumulated in the box to trip a control circuit which actuates the feed roller motor to move the desired length of web through the processing station and then stop for a preselected interval. The circuit also controls the processing station to synchronize its operation with that of the web feed and the entire sequence is repetitive at high speed.Type: GrantFiled: June 21, 1974Date of Patent: April 6, 1976Assignee: Packaging Industries, Inc.Inventor: John L.

Patent number: 3946921Abstract: An automatic apparatus for feeding packaging strap, including a strap feeding mechanism having a pair of reversibly rotatable feed rolls for feeding and returning the strap and a detector for detecting the amount of strap fed and returned. Strap is fed to the feeding mechanism by a prefeeding mechanism having unidirectionally rotatable prefeed rolls and a detector for detecting the amount of strap prefed. A control mechanism determines the difference between the amount of strap fed and returned by the feeding mechanism and controls the prefeeding mechanism to prefeed an amount of strap equal to the difference.Type: GrantFiled: March 25, 1974Date of Patent: March 30, 1976Inventor: Atushi Noguchi
