Title: Process for the production of soluble high molecular weight polyurethanes which are free from isocyanate groups
IPC: C08G18/00
Filed: 1976-04-09
Abstract: This invention relates to an improved process for the production of high molecular weight polyurethanes which are free from isocyanate groups and are soluble in organic solvent in reduced reaction times. The reactants, polyol and isocyanate, for example, are mixed together with solvent and the temperature is permitted to rise under the effect of the heat of reaction. The reaction mixture is then cooled with solvent addition in such a way that the viscosity of the reaction mixture remains constant until the optimum temperature for the polyurethane formation reaction ("specific reaction temperature") is reached. The mixture is then gradually cooled until there is no residual isocyanate present and the polymer is recovered from the reaction mixture.

Patent ES-466097-A1 (ES)
Title: Apparatus for forming glass containers
IPC: C03B9/30
Filed: 1978-01-18
Abstract: Apparatus for forming glass containers by the blow and blow process in which a parison mold having a plurality of cavities is centrally positioned relative to a pair of blow molds having a plurality of cavities. The parisons are formed with their necks down in the parison mold from a charge of glass delivered to each cavity. Vacuum is applied to the neck area of the mold to form the finish portion of the container. A neck pin is pulled and air under pressure is fed to the interior of the area from which the neck pin is drawn to expand the glass within the parison mold at a continuous rate until the glass within the parison mold comes in contact with a baffle which closes the upper end of the parison mold. The parison mold is then opened and the parisons are transferred alternately from the parison mold to the blow molds where they are expanded into final shape. During the transfer of the parisons from the parison mold to the blow mold, air under pressure is maintained within the hollow interior of the parison. The parison transfer mechanism carries the neck molds with parison counterblow pressure delivering means as well as puff or low pressure means for either puffing the parison during its invert movement from the parison mold to the upright position at the blow mold or to help sustain the parison against collapse during invert. The ability to apply puffing air to the parison during transfer is a significant step in the forming process.

Abstract: 1-[ alpha -(Carboxy)-4-hydroxybenzyl]-3 beta -aminoazetidin-2-one esters are prepared by converting 2-acyl-3,3-dialkyl-7-oxo- alpha -[4-(benzyloxy)phenyl]-4-thia-2,6-diazabicyclo[3.2.0]-heptane-6-acetic acid esters with mercuric acetate in an aqueous organic solvent mixture, e.g., in aqueous methanol, to 7-oxo-3-phenyl- alpha -[4-(benzyloxy)phenyl]-4-oxa-2,6-diazabicyclo[3.2.0]hept-2-ene-1-acetic acid esters and the latter are reacted with PCl5 and pyridine to provide the monocyclic 1-[ alpha -(carboxy)-4-benzyloxybenzyl]-3 beta -( alpha -chlorobenzylideneamino)-4-chloroazetidin-2-one esters. Reduction of the dichloro azetidin-2-one with an organo tin hydride and azobisisobutyronitrile affords the deschloro, 1-[ alpha -(carboxy)-4-benzyloxybenzyl]-3 beta -benzylideneaminoazetidin-2-one ester. The latter is hydrolyzed and the 4-benzyloxy group is cleaved via catalytic hydrogenolysis to yield an ester of 1-[ alpha -(carboxy)-4-hydroxybenzyl]-3 beta -aminoazetidin-2-one. The 3 beta -amino ester is useful for the preparation of the antibiotic FR 1923 (nocardicin).

Title: A process for the stereo-specific or stereo-selective preparation of imidazolyl-oxime ether derivatives and imidazolyl-oxime derivatives.
IPC: A61P31/04
Filed: 1979-05-23
Abstract: 1-Aryl-2-(1H-imidazol-1-yl)-ethanone oxime ethers are known to exist as a mixture of isomers corresponding to the formulae: < IMAGE > To prepare such an isomer in a stereospecifically pure form, the pure stereoisomer of the corresponding ethanone oxime is first converted into an alkali salt in a polar solvent, such as acetone or dimethylformamide, using an alkali in an amount somewhat less than the equimolar amount with respect to the said ethanone oxime, and is then converted to the desired ether by reacting it at a temperature not higher than 40 DEG C. with a halogen compound capable of forming the desired ether. Isolation of the ether product is obtained as the free base or by precipitating it as an acid addition salt upon addition of a suitable organic or mineral acid, preferably nitric acid. A stereospecific ethanone oxime in either its trans- or cis-isomer form corresponding to the formula: < IMAGE > can be stereospecifically synthesized from the corresponding 2-halogen ethanone having the formula A-CO-CH2-Hal (IV) which, in making the cis oxime (IIc), is first converted with imidazole or a suitably substituted derivative thereof and subsequently oximated by reaction with hydroxylamine in the presence of a molar excess of an alkali at an elevated temperature or which, in preparing the trans oxime (IIt), is first oximated by reaction with hydroxyl-amine under mild conditions and subsequently converted in the cold with imidazole or a suitably substituted derivative thereof. The products are effective fungicides or bactericides and consequently useful as thermotherapeutic agents in combatting undesirable lower plant organisms in the fields of human as well as veterinary medicine and also as fungicides in agriculture and horticulture.
