US Patent:

40260798, May 31, 1977

Filed:

Oct 3, 1975

Appl. No.:

5/619529

Inventors:

Ronald G. Morris - Beaver Falls PA

Assignee:

Beaver-Advance Corporation - Ellwood City PA

International Classification:

E04H 1218

US Classification:

52122

Abstract:

A skeletonized, adjustable, high-rise scaffold assembly employs stacked sections, each made-up of a pair of opposed end frames or panels. The end frames of cooperating upper and lower sections are each provided with a pair of main or outer, supporting side legs and retained latching pin means for vertically adjustably connecting the sections together. Side legs of each end frame have a pin connector extending inwardly within a plane of the frame to removably receive ends of cross brace members that are mounted to extend from an end frame of one section diagonally across in a connected relation with an opposed end frame of the other section. The cross brace members have spaced-apart latching hole portions at at least one of their ends to enable a selection of a proper hole portion that is related to or compatible with an up or down adjustment of the frames of an upper section with respect to frames of a cooperating lower section. In one embodiment, the section bracing connections are made between inner or secondary leg members of the opposed frames, and in another embodiment, the connections are between main or outer leg members of the opposed frames.

Abstract:

A shoring or scaffold for construction, maintenance and other work, using stacked scaffold sections of a demountable type and having a heighth adjusting construction is provided. Each section has a pair of spaced-apart end frames that are demountably cross-connected with respect to each other and the end frames of upper and lower sections have a telescopic adjustable relation to meet heighth requirements. To provide strength and support rigidity, dual-tire bracing members are utilized to extend from the end frame of a lower section across and in an interconnecting relation with an opposed end frame of an upper section. A simple adjustment of the bracing members in conformance with vertical adjustments made between upper and lower sections is accomplished by utilizing members that at one end have a gooser pivot mounting on a horizontally extending connecting member of a frame of one section and that at the other end have a latching arm which is provided with a group of spaced-apart latching hole portions whose spacing is proportioned to vertical adjustment positions between the upper and lower sections. The latching hole portions are adapted to selectively detachably latch with a single latching pin means which is carried in a protected relation on an inwardly offset, short length or secondary leg member of the opposed frame of the other section. This enables the use of a single brace member for different heighth adjustments of stacked sections.

Abstract:

Method and apparatus for enhancing removal of corrosion products from a nuclear reactor piping system. A reagent is supplied into a multi-part reactor piping system to react with the corrosion products therein. The corrosion products dissolve into the reagent to define a contaminated solution. The contaminated solution is brought into contact with an ion exchange resin bed that absorbs the corrosion products from the contaminated solution to define a reagent-containing contaminant-free solution. In this regard, a circulation pump having a predetermined net positive suction head (NPSH) interconnects the system with the resin bed for pumping the contaminated solution from one part of the reactor piping system and into contact with the resin bed and thereafter pumping the contaminant-free solution from the resin bed and to another part of the reactor piping system to remove the corrosion products. Moreover, a gas injector injects a pressurized gas into the reactor system to pressurize the reactor system to a predetermined pressure necessary to maintain the NPSH during transfer of the contaminant-free solution from one part of the piping system to another part of the piping system. During each transfer, the pump brings substantially all contaminated solution into contact with the resin bed as it removes substantially all the corrosion products from the piping system.
