Abstract: An apparatus is disclosed for the resilient spinwelding of two (thermoplastic) body portions to one another. The incorporation of resilient members between the prior art "hard surfaced" spinweld apparatus and the body portions to be welded together significantly decreases the spinweld time, and in the case of container/lid systems used for food packaging, increases the burst pressure of the container/lid.

Abstract: Oil recovery method using polymer solutions in which highly permeable strata are made significantly less permeable while less permeable strata are not made significantly less permeable. This is accomplished by heating more permeable strata by injection of hot fluids, and then injection of a crosslinkable vinyl aromatic-conjugated diolefin polymer and a temperature activated crosslinking agent. A crosslinked gel is formed in the initially more permeable strata, permitting recovery of oil from the initially less permeable strata.

Abstract: Improved compositions comprise polymer blends of a linear alternating polymer of carbon monoxide and at least one ethylenically unsaturated hydrocarbon with an amorphous polyamide, and, optionally, an acidic polymer containing moieties of an .alpha.-olefin and an .alpha..beta.-ethylenically unsaturated carboxylic acid. The blends demonstrate improved transparency.

Abstract: This invention discloses a method of fabrication of a shelf stable, dimensionally heat stable, impact resistant, retortable, hot fillable container apparatus which is suitable for oven use. The container apparatus has a shaped first material layer formed from a linear alternating polymer of carbon monoxide, ethylene and propylene, and a cooperatively shaped second material layer formed by coating a copolymer of vinylidene chloride material on at least one untreated side of the first material layer, preferably by impact spraying. The thicknesses of the material layers are selected such that the water percent weight loss per year of any contents stored in the container is less than 3% per year.

Abstract: Laminated billets are made by extruding a plurality of sheets, cooling and stacking said sheets to form a stack, laminating a portion of said stack using radio frequency radiation, cutting out at least the laminated portion from the stack and returning the resulting individual webs to their respective sheet extrusion process.

Abstract: A method for the design of a pressure vessel which incorporates two ends of a straight wall cylinder which are capped and sealed to form a container capable of holding the vessel contents under pressure. This method is applicable to metal as well as non-metal vessels and to vessels having unusual shapes or combinations of such geometries, such as square, oval, triangular, complex and irregular curves or combinations. The vessel may be made on a continuous basis from endless lengths of vessel stock continuously cut to length.
