Abstract: A non-catalytic process for the preparation of N-(tertiaryaminoalkyl)acrylamides is disclosed which comprises subjecting a corresponding .beta.-aminopropionamide to a pyrolysis temperature of about 180.degree. to 300.degree. C. after storage of the .beta.-aminopropionamide in an atmospheric holding tank at a temperature of about 150.degree. to 220.degree. C. from eight to seventy-two hours prior to pyrolysis. The corresponding .beta.-aminopropionamide compounds can be prepared by mixing and reacting at least two moles of a tertiaryaminoalkyl amine with an acrylic acid or ester compound. The inventive process provides the production of the N-(tertiaryaminoalkyl)acrylamides in high yields with minimal back addition or polymerization and greatly reduced acid impurity levels.

Abstract: Use of stannous halide alcohol complexes, typified by the complex of stannous chloride and triethylene glycol, as catalysts permits production of urethane elastomers characterized by freedom from bubbles. The novel complexes are particularly characterized by their properties; e.g. Mossbauer spectra shows a chemical shift relative to a standard and a quadrupole splitting which are not found in mere mixtures of e.g., stannous chloride and triethylene glycol.

Abstract: The hot raw synthesis gas stream leaving the reaction zone of a free flow partial oxidation gas generator at a temperature in the range of about 1800.degree. to 3000.degree. F. is passed through a first gas diversion and residue separation zone where the velocity of the gas stream is reduced and its direction is diverted into a side transfer line. Solid material and molten slag separate by gravity from the gas stream. The hot gas stream is then introduced into a second gas diversion and residue separation zone where additional residue is separated. About 0.5 to 20 vol. % of the hot gas stream may be passed through bottom outlets in said first and second gas diversion zones in order to prevent bridging. The hot gas stream from the second gas diversion zone is passed upwardly through a radiant cooler where additional solid matter is removed by gravity and the gas temperature is reduced to a temperature in the range of about 900.degree. to 1800.degree. F.

Abstract: Marine structure adapted to be fixed to the ocean floor for drilling wellbores into the latter. A drill conductor cage is removably positioned within the marine structure at a submerged position. The cage holds one or more drill string or conductor guides in a manner that a number of directionally oriented wells can be drilled without movement of the structure. The cage is readily disengaged from its underwater working position to permit it to be raised to the water's surface and is then swung outboard of the platform's working deck. In such a position the addition and removal of drilling cnductors is facilitated without undue use of limited deck space on the platform.
