Disclosed are a method and apparatus for laying down, abandoning and/or recovering a pipe on the sea floor. During lay-down and abandonment, the pipe is lowered by a high capacity winch to an intermediate depth, at which the loading exerted by the pipe has dropped to within the rated capacity of a low capacity winch, to which the loading is then transferred. The high capacity winch line is then recovered to the attendant vessel and the pipe lowered to the sea floor using the low capacity winch. Pipe recovery is essentially a reversal of the above procedure. In this way, the length of the line of the high capacity winch is considerably reduced, which reduces the winch size and hence cost.

The invention includes an ear or nose plug and a method of forming such an ear or nose plugs. The method may include providing silicone rubber base and catalyst materials and mixing about equal parts of the silicone rubber base and catalyst materials to form a homogeneous putty. The method may further include forming a bullet shaped and sized module of the homogeneous putty. The method may further include inserting the module within an ear or nose cavity using enough gentle pressure to allow the module to conform to the ear or nose cavity and leaving enough of the module outside of the cavity to grasp for removal. The method may further include waiting a predetermined amount of time to cure and removing a custom shaped ear or nose plug. Embodiments of an ear or nose plug formed by the above method are also disclosed. The ear or nose plugs are formed in situ and quickly cure according to the methods of the present invention.

Buoys are used for mooring purposes and as navigational marks. An embodiment of the invention is be explained in relation to catenary anchor leg mooring (CALM) buoys.Conventional CALM buoys generally have a hull constructed of steel plate by traditional ship building techniques requiring plate benders. Webs, beams and girders are welded inside the hull which is divided into several tanks. The buoy has a central moonpool and a steel turntable. Bending plate, in effect, doubles its cost.A method of constructing a buoy is disclosed, comprising: constructing a framework and affixing flat steel plate to it.

An Electro-mechanical device utilizing a fiber optic based sensor (Fiber Optic strand) for the purpose of detecting and extinguishing a fire momentarily after ignition. A light signal transmitted through the sensor (Fiber Optic strand) is used as a means to urge a spring loaded valve (Firing Valve) against its established position, thus blocking the dispersal of fire suppressing agents. This condition will persist until the sensor (Fiber Optic strand) is damaged by the presence of open flame in close proximity.

The present invention relates to genetically attenuated superantigen toxin vaccines altered such that superantigen attributes are absent, however the superantigen is effectively recognized and an appropriate immune response is produced. The attenuated superantigen toxins are shown to protect animals against challenge with wild type toxin. Methods of producing and using the altered superantigen toxins are described.

The present invention provides methods for stabilizing proteins, preventing protein aggregation, renaturation of previously-denatured proteins, reactivating a protein that has been inactivated by denaturation, preserving enzyme activities under conditions of elevated temperatures, inducing thermotolerance in bacteria, increasing the temperature optimum for the activity of an enzyme, and preventing formation of inclusion bodies by bacterially-expressed recombinant proteins.
摘要:
Disclosed herein are polypeptides and variants thereof comprising a polypeptide sequence having substantial identity to ricin A chain (RTA) that lack detectable N-glycosidase-rRNA activity or exhibit reduced N-glycosidase-rRNA activity as compared to controls and methods of making and using thereof. The polypeptides and variants have a greater solubility in aqueous solutions of physiological pH and ionic strength than RTA and also retain the integrity of the neutralizing immunological epitope of wild type RTA. Also disclosed are immunogenic compositions that may be used to immunize a subject against ricin intoxication. Methods of immunizing against, treating, and preventing ricin intoxication are disclosed.
