Abstract: A frame apparatus for holding a flexible lance positioning mechanism adjacent to and spaced from a heat exchanger tube sheet includes an upper guide rail, a lower guide rail, a positioner rail supported from one of the upper and lower guide rails and guided by the other of the upper and lower guide rails, and a rail clamp assembly fastened to a portion of a tube sheet. This rail clamp assembly has a flat plate member fastened to the tube sheet, a base plate spaced from the flat plate by one or more threaded shafts, and one or more clamp fingers rotatably fastened to the base plate. Each clamp fingers is operable to rotate toward the base plate when the base plate is drawn against the flat plate or beam member by rotating the threaded shaft, thus drawing the rail securely to the flat plate of the clamp assembly.

Abstract: A guide tube pitch adjustment apparatus for aligning distal ends of lance guide tubes in registry with tube openings in a heat exchanger tube sheet is disclosed. A guide tube pitch clamp assembly carried within and supported from a housing. The pitch clamp assembly has at least two V-blocks fastened to a threaded rod. One V-block is fastened to a portion of the threaded rod having right hand threads, and another V-block is fastened to another portion of the threaded rod having left hand threads. Each of the V-blocks supports a portion of one of the guide tubes, and a cross bar clamp within the housing is oriented to span across the V-blocks and adjustably hold the portions of the guide tubes in a spaced relationship such that spacing between the distal ends of adjacent guide tubes may be adjusted by rotation of the threaded rod.

Abstract: A method and system for providing distributed network access point installation and management. A network provider installs and/or operates a plurality of access points at locations of a retail entity. Each access point may provide services such as Internet access, and/or content such as audio, video, text, and/or graphics, among other types of services. A carrier, such as a telephone or cable company, may compensate the network service provider for installation and operation of the access points. The carrier may in turn charge its subscribers for network access at the retail entity locations. A plurality of different carriers may provide compensation and allow respective subscriber access. The network access points may be configured to allow each carrier to present a point of presence to its subscribers at the retail entity locations. The installed network may also provide service for retail entity back office functions.
