摘要:
When producing hydrocarbons from fatty acid esters contained in fats or fat oils, the fatty acid esters initially are split up by hydrolytic decomposition into a first stream containing crude alcohol and water and a second stream containing free fatty acids, and subsequently the free fatty acids of the second stream are hydrogenated with hydrogen to obtain saturated hydrocarbons.

Carboxylic anhydrides are highly suitable as additive for industrial materials, cosmetics, pharmaceutics and foodstuffs, in particular beverages, for protecting them against attack and/or destruction by microorganisms.
摘要:
A method for improving the permeability barrier against water vapor and gases for a flexible support material which includes at least one barrier layer consisting of a ceramic material. According to this method, the ceramic barrier layers are coated with a solution of perhydropolysilazane (PHPS), and then are cured to form a silicon oxide layer.
摘要:
A flexible packaging material for sterile items, made from a film, or a film composite (B) with barrier properties, comprises a support film made from polyamide, polyester, or polypropylene and a thin ceramic layer arranged thereon. A functional layer containing, or made from an inorganic/organic hybrid polymer is applied to the thin ceramic layer on the support film.
摘要:
A covering for lining acoustically excited surfaces includes an upper cover layer and a flush fitting lining that adheres to the rear side of the cover layer. The lining has sound deadening properties and is made of a plurality of lining modules. A method of manufacturing such a covering for acoustically excited surfaces includes the steps of forming a cover layer and lining the modules and applying the modules to the cover layer.
摘要:
A plug connector in which the cables are led out at an angle and a secondary lock, comprising a plug part (1) on which there are disposed at least two opposite tongues (2a, 2b) disposed parallel to the plug axis (3) and having outwardly pointing catches (4a, 4b), and a socket part with correspondingly arranged slots to receive the tongues (2a, 2b) and for engagement of the catches (4a, 4b) on correspondingly disposed shoulders. The tongues (2a, 2b) in the plug part (1) extend toward the back wall (5). The surfaces (6a, 2b) of the tongues (2a, 2b) oriented toward the plug axis (3) are bevelled away from the plug axis (3) toward the back wall (5). The tongues (2a, 2b) are arranged to pivot on the plug housing over substantially half their length. The back wall (5) is formed with slots (7a, 7b) in the region of the bevelled side surfaces of the tongues (2a, 2b), such that a U-shaped yoke (8), on insertion of its limbs (8a, 8b) into the slots, forces the tongues (2a, 2b) away from the plug axis (3) in this zone so that the opposite ends of the tongues (2a, 2b) are moved with the catches (4a, 4b) towards the plug axis (3).
摘要:
A hinge fitting for pivotably and selectively locking the back rest of a vehicle seat to the vehicle frame has two planetary gear sets, formed as mirror-images of one another. Both sets have the same reduction ratio and the eccentrics of the two planetary gear sets are rotated toward each other at most by a small angle.
摘要:
A method of producing molded articles from polyolefin molding compositions crosslinked by irradiation, to which molding composition is added, prior to irradiation, by mixing and/or copolymerizing, from 0.3 to 20 percent by weight of vinylacetate, optionally in a form as pre-copolymerized with a polyolefin. The occurence of undesirable accumulations and discharges of electrical charge concentrations and/or the undesirable foaming of the polyolefin molded articles will thus be suppressed.
摘要:
Method of stabilizing drinks which is characterized in that A) the drink is admixed with limonene or limonene-containing formulations and B) subsequently dialkyl dicarbonate, in particular dimethyl dicarbonate, is added to the drink.
