Abstract: A lightweight flexible air supported enclosure which may be used as a shelter for covering storage areas, greenhouses and various other uses which may be erected inexpensively on site from strips of flexible sheet material attached together at seams using adjacent pairs of reinforcing cords or cables with the seams being sealed by internally hanging edge flaps of the sheet material. The seal is created by the flaps being held in surface to surface contact by the internal pressure of the envelope. This enclosure is especially suited for assembly on uneven surfaces without preparing the surface of the perimeter on which the enclosure is to be mounted.

Abstract: An apparatus for rapidly filling a pressure vessel such as a fuel storage tank with highly pressurized gas by initially inserting into the tank, a measured quantity of liquefied natural gas (LNG) or some other type of cryogenic liquid and permitting the temperature of the liquid to rise within the tank to vaporize it into a gas under a pressure which at least approaches the design working pressure of the tank. The storage tank maintains the gas under sufficiently high pressure that automotive fuel tanks or other small tanks can be rapidly filled from the storage tank without compressors due to the high internal pressure of the storage tank.

Abstract: A composite tread has at least a low hysteresis component and a high hysteresis component therein. The components are geometrically arranged such that upon wear, generally more of the high hysteresis compound is exposed as wear progresses which imparts good traction to the life of the tread.

Abstract: This invention relates to a method of forming shaped articles utilizing liquid functional group polymers compounded with suitable compounding agents to produce mixtures of extremely viscous nature and moving these viscous mixtures to a shaping device without the entrapment of air.

Abstract: A method of polymerization of butadiene to form polymers with a high (greater than 90 percent) content of cis-1,4 configuration wherein a mixed fluoride bearing catalyst system is utilized to control the polymerization rate and the molecular weight.
