Abstract: Water-jet cleaning system and a method of cleaning a heat exchanger. The equipment includes a rotary tool having a lance with at least two degrees of freedom. The lance's movements relative to openings defined in the heat exchanger face plate are controlled via a smart indexing controller. The controller includes an electronic communication device that is specifically programmed to selectively activate various components of the rotary tool and a water delivery system. The programming utilizes an observed, learned, or uploaded pattern of the heat exchanger tube openings to selectively rotate the lance relative to the rotary tool's mounting assembly or linearly move the lance towards or away from the mounting assembly. The controller moves the lance to align a nozzle thereon with a selected opening in the face plate and then delivers a high pressure water jet therethrough.

Abstract: Workpiece-holding tools and techniques are described. Workpiece-holding tools and techniques are usable to ensure consistent and durable alignment of various workpieces while providing access for performing attachment techniques thereon. In one example, the workpiece-holding tool is configured to allow objects to be held or removably affixed to an alignment surface. Holding objects with the workpiece-holding tool ensures that the alignment of objects with an alignment surface does not change while a user is operating upon a workpiece, e.g., as by joining aligned objects together, without interfering or obstructing access to the objects. The ability to hold objects is enhanced by the inclusion of cutouts that provide increased access to interior surfaces of the workpiece-holding tool, such as to increase the area available for use of clamps or other fastening devices.

Abstract: A method for mounting a guide rail in an elevator system elevator shaft first carries out mounting steps by a mounting device having a carrier component, an installation component and a control apparatus controlling the installation component. The control apparatus determines, on the basis of an actual position of the mounting device and a desired position of a guide rail to be installed, a position of a marking on a shaft wall of the elevator shaft relative to the actual position of the mounting device. Based on the marking, an installation step determines the desired position of the guide rail. The marking is applied to the shaft wall by the installation component. The previous steps are followed by the steps of alignment the guide rail in relation to the marking and fastening the guide rail to the shaft wall, which steps can be performed manually by an installer.
