Abstract: A method of inhibiting hydrates in a fluid comprising water and gas comprising adding to the fluid an effective hydrate-inhibiting amount of a composition comprising one or more homo- or co-polymers of N-alkyl(alkyl)acrylamide synthesized by polymerizing one or more N-alkyl(alkyl)acrylamide monomers in a solvent comprising a glycol ether of formula CH3—(CH2)m—(O—CH2—CH2)n—OH where m is an integer of 0-1, and n is an integer ?1.

Abstract: Disclosed herein are corrosion inhibiting compounds and compositions useful in applications relating to the production, transportation, storage, and separation of crude oil and natural gas. Also disclosed herein are methods of using the compounds and compositions as corrosion inhibitors, particularly in applications relating to the production, transportation, storage, and separation of crude oil and natural gas.

Abstract: A method of inhibiting hydrates in a fluid comprising water and gas comprising adding to the fluid an effective hydrate-inhibiting amount of a composition comprising one or more copolymers of N-alkyl (alkyl)acrylamide monomers and one or more cationic monomers selected from acid and alkyl chloride quaternary salts of N,N-dialkylaminoalkyl (meth)acrylates and N,N-dialkylaminoalkyl (meth)acrylamides.

Abstract: Disclosed and claimed is a composition and method of inhibiting the formation of hydrate agglomerates in a fluid comprising water, gas, and optionally liquid hydrocarbon. The composition comprises the following formula and the method comprises adding to the fluid an effective anti-agglomerant amount of any of the following formula and optionally salts thereof. R1, R2, and R3 are each independently CnH2n+1 or benzyl. R4 is C4-C20 alkyl or alkenyl. n is an integer from 0 to 10. X? is a counterion.

Abstract: A phototriggerable composition and method for use in crosslinking protein such as collagen comprising application of a tethered diazopyruvate composition followed by irradiation, whereby the composition results in the sutureless wound closure of, for example, a tendon or cornea.

Abstract: A method for thread laying and a thread laying machine; thread laying has been achieved by a machine that has a vacuum table and above it a gantry with a thread dispensing device on a shuttle operating in an x- and y- direction; the gantry may be fixed to a pair of carriage on the x-axis driven in unison or each of the carriages may be independently driven; curved threads as well as threads on a mold may be laid down on a substrate; typical material produced is sail material of considerable thread pattern complexity; single threads or a multiple of threads may be laid down through one thread head with an adhesive properly coating the threads; multiple thread heads as well associated apparatus such as laser cutters and the like are mounted on the gantry.

Abstract: A spinnaker wherein the head section of the spinnaker incorporates a novel panel and sub-panel layout which improves the control of the spinnaker in use and allows projection of a greater sail area.

Abstract: An improved sail of thread and polymer film construction including for panels and at corners of sail foam layers; novel batten pocket construction includes foam-film combinations.

Abstract: A sail wherein the loads thereon in use are carried predominantly by structural members properly disposed within the sail.

Abstract: An improved structural sail with stress bearing members specifically oriented along the leech to eliminate and/or minimize "hard" leech or leech "fall-off".

Abstract: Sails made with threads running in the direction of principal stresses in a laminate made of the threads laminated to a film material, such as Mylar.

Abstract: An improved structural sail with grid members appropriately positioned to resist aerodynamic loads.

Abstract: A sail and a method for constructing a sail or any pliable lifting surface where the lift for or the motive power therefor is wind.
