摘要:
A needle cannula with a first end and a second end wherein a section near said second end must be shaped into a coiled spring and then pulled into a biased spring needle cannula without destorting the inside surface of said spring needle cannula. A wire of suitable section is inserted into said cannula of said spring needle cannula and wherein said first end of said spring needle cannula is inserted into a hole formed in a retainer plate and wherein a portion of said spring needle cannula with said wire in said cannula is wrapped or coiled about a coil bar wherein said needle cannula is formed into a spring needle cannula and wherein the inside walls of said cannula cannot deform due to said wire disposed in said cannula. The coiled spring needle cannula with said wire inside is removed from said coil bar and further installed into a modullar hub chamber and further stretched to a suitable length wherein said stretched spring needle cannula becomes a biased spring needle cannula wherein said biased spring needle cannula is inserted into a hub chamber and wherein said biased spring needle cannula is suitably fixed to said hub chamber wherein said first end of said biased spring needle cannula extends forward froming a straight needle cannula and wherein said wire is removed from said biased spring needle cannula.
摘要:
A cutter-coiler device that economically cuts and coils cylindrical piles, casings and conductor pipes to a depth below the surface of the sea floor. Although the device will cut and coil cylindrical piles, casings and conductor pipes above the sea floor, it is most effective for use where casings, conductors and piles must be cut, and pushed or coiled below the sea floor. Further, although the device is effective in cutting and coiling casings, conductors and piles that are cut below the sea floor, it is also effective on cutting and coiling cylindrical piles casings and conductor pipes that must be cut above the sea floor. The device includes a conventional pile driver or hammer, an anvil, a helmet, a spreader coiler, a coiler, cutter blades and a guide. The guide directs the cutter blades into the casing where the cutter blades cut the casing into sections and the spreader coiler pushes out on the sections causing the cut sections to flatten out and the coiler forces the section to roll up into a coil.

A disposable hypodermic syringe having a needle cannula fixed to a piston assembly. The piston assembly is held within the elongated hollow barrel of said hypodermic syringe by a compressed spring and a trigger. When said trigger is disengaged with said piston assembly said spring pushes said piston assembly and said needle cannula into said barrel of said hypodermic syringe and holds said needle cannula fixed to said piston assembly within said barrel and is further prevented from being pushed out of said elongated hollow barrel by a rim in said elongated hollow barrel thus preventing any accidental injection of bacteria, virus or other undesirable material into others. The disengagement of said trigger with said piston assembly is accomplished with only one and the same hand that is used to inject the needle cannula and medicament into a body.

摘要:
A method and apparatus for transporting a marine superstructure on a vessel floating in a body of water to a working site, placing the semi submersible part of the apparatus into a body of water, lowering the semi submersible into a stable position, moving the marine superstructure from the vessel and onto the semi submersible, elevating the semi submersible with the marine superstructure over the marine structure, lowering the semi submersible vessel and the marine superstructure, causing the marine superstructure to rest on the marine structure, pulling the semi submersible away from the marine structure and marine superstructure and placing the semi submersible back onto the vessel. To remove the marine superstructure from the marine structure and place the marine superstructure onto the vessel the same method is used in reverse.

摘要:
A structure for use in supporting a platform above a body of water is disclosed. The structure includes a leg extending between the bed of the body of water, the seabed, and the platform. The overall cross-sectional area of the leg is greatest near the seabed and decreases moving upwardly away from the seabed.

A recoverable or permanent rigid subsea form having retaining walls to contain fill material to stabilize, raise and/or provide a level surface above the sea floor. Portions of the retaining walls comprise hollow tanks that are alternately flooded and emptied to control the buoyancy of selected portions of the form. Alternatively, the retaining walls comprise solid plates. Means are provided in the retaining walls for allowing offshore equipment to pass into and out of the form.The form is set in place on or below the sea floor and the fill material is placed in the form. The fill material is leveled by gravity or other means to form a level surface at the desired elevation. Drilling and/or production equipment can then be placed on the level subsea surface.

A retractable needle cannula module for connecting to a conventional syringe has a biased spring needle cannula. The spring needle cannula is biased and locked to prevent the spring needle cannula from pulling the needle into the hub chamber. After medicament has been injected into a body, the spring needle cannula is released and trapped inside the hub chamber.
