Patent Number Title Of Patent Date Issued
5070566 Hybrid bridge structure December 10, 1991
A hybrid bridge construction comprises a pair of piers enclosed in the earth at a fixed predetermined distance apart with a cantilever section supported on each pier. Each cantilever section comprises one or more vertical towers with a pair of inner and outer rigid compression members
5058330 Self-supporting membrane structure for use on the moon October 22, 1991
A self-supporting pressurized or unpressurized membrane structure for lunar habitation and operation. The pressurized membrane is made up of continuous and leak-proof fabric membrane that encapsulates the entire structure and is capable of withstanding temperatures of about -190.degr
4907312 Bridge and method of installing prefabricated bridges and bridge structure March 13, 1990
A bridge and a method of constructing the bridge over water. A bridge span is positioned longitudinally in portion through a slot in a bridge pier; then the span is moved laterally through the slot to a position in the center of the pier at a low level. Then the span is hoisted up to its
4702052 Prestressed concrete pressure vessel and method for making such a vessel October 27, 1987
A pressure vessel and a method for distributing the stresses in a thick-walled high-pressure vessel, so that they lie within allowable limits, by constructing the wall in a series of generally concentric layers, at least one intermediate layer of which is to be constructed before the
4389825 Prestressed concrete pressure vessels with increased pressure-retaining capability June 28, 1983
A prestressed concrete pressure vessel capable of containing extremely high pressures in an internal cavity, 10,000 psi and higher, is constructed in such a way as to enable the application of extremely high circumferential prestressing force at the outer cylindrical surface. The extreme
4373837 Pier with prestressed resiliant integral deck to absorb docking forces of ships February 15, 1983
In a pier having a series of spaced-apart horizontal pile caps surmounting and connecting the supporting piles together transversely of said pier, there is an integrated one-piece deck supported atop the pile caps so that it can slide thereon. A series of prestressing tendons connect the
4313902 Prestressed concrete pressure vessels February 2, 1982
A prestressed concrete pressure-containment vessel having one or more cavities within its external shell. The cavities, whether cylindrical or other shape, are totally contained by prestressing tendons, which apply forces to contain various pressures within the structure. By permitting
4265066 Prestressed concrete pressure vessels May 5, 1981
A prestressed concrete pressure-containment vessel having one or more cavities within its external shell. The cavities, whether cylindrical or other shape, are totally contained by prestressing tendons, which apply forces to contain various pressures within the structure. By permitting
4112697 Method of producing and installing offshore structures September 12, 1978
The method uses a construction and launch barge having a shallow draft hull with a construction deck supporting at its center a floatable offshore structure both during construction thereof and during the towing of the barge to the site where the offshore structure is to be installed. In
4015554 Construction and launch barge and method of producing and installing offshore structures April 5, 1977
A construction and launch barge having a shallow draft hull with a construction deck supporting at its center a floatable offshore structure both during construction thereof and during the towing of the barge to the site where the offshore structure is to be installed. In order to mainta
4000624 Multi-component offshore platform January 4, 1977
A multi-component offshore platform having a floatable and ballastable central column with a base that is adapted to rest on the bottom of the sea. The column is towed to its site while floating and then upended and ballasted to sink the base to the proper site. A hitch collar is slidabl
