Abstract: A servicing machine for a steam generator is accurately set up in the generator channel head with a pivoted arm mounted for rotation in a plane parallel to the tubesheet. The angular position of the arm, the longitudinal position of a carriage mounted on the arm and the vertical position of a platform on the carriage are remotely controlled to maneuver a probe used in mapping the precise location of the thousands of holes in the tubesheet. Various operations are then performed at each precise hole location by tools carried by the arm mounted carriage to prepare for installation of new tubing. The operation of a pair of remotely controlled pivoted arms, one on each side of the channel head divider plate, is coordinated to automatically position the ends of U-shaped tubes in corresponding holes in the tubesheet on opposite sides of the divider plate and to secure the same in place.

Abstract: A closure mechanism for an injection molding machine or extrusion press having a frame, a number of parallel extending rods, a first tool support fixedly connected with the frame and a second tool support displaceable along said rods. There is also provided a hydraulic mechanism or device for displacing the second tool support along the rods. According to the invention the rods possess engaging means and the second tool support possesses engaging elements which can be engaged in the engaging means of the rods. The rods are displaceably connected with the first tool support and the hydraulic device possesses at least one displacement mechanism serving to displace the second tool support with respect to the rods and for each rod possesses an additional displacement mechanism fixedly connected with the first tool support which serves to displace the relevant rod with respect to the first tool support.
