Abstract: A process for recovering glycols from used glycol-containing technical fluids, especially from used antifreeze comprises adding to the used glycol-containing technical fluids an organic solvent which forms with the glycol to be separated off an azeotropic mixture which has a lower boiling point than the glycol itself and distilling off this azeotropic mixture.

Abstract: The invention relates to cleaning compositions in the form of microemulsions for cleansing the skin or for the manual cleaning of hard surfaces. These cleaning compositions consist of oil, water, surfactant and cosolvent. As surfactant, use is made of a surfactant system consisting of 80-100% alkylpolyglycoside and 0-20% auxiliary surfactant, of anionic, nonionic or betaine type, whose choice is largely arbitrary. The cosolvent is an oligoester of polybasic carboxylic or hydroxycarboxylic acids with C.sub.1 to C.sub.4 alcohols. The microemulsions are highly stable and can be diluted in water without problems.

Abstract: Low-foaming, liquid or pulverulent machine detergents today consist, in the surfactant portion, mainly of surfactants based on petrochemicals; the biodegradability and ecotoxicity frequently does not reach the level of surfactants based on natural materials. Accordingly, a surfactant combination for low-foaming machine detergents is proposed, which is predominantly prepared from renewable raw materials; washing results and biodegradability are excellent. The surfactant portion of these machine detergents consists of fatty alcohol ethoxylates, soaps and alkyl polyglycosides which consist at least of a mixture of alkylglycosides of varying chain length and varying degrees of glycosylation.

Abstract: The invention provides a device for applying a fluid medium onto the surface of an article. It comprises a tightly sealed, preferably metallic storage container and a fluid application assembly including a sleeve member and an application member which latter is laterally covered by the sleeve member when the device is in its inoperative position. Upon executing a relative movement between sleeve member and storage container, a locking member is destroyed, a seal of the container is broken and the application member is exposed such that the device is ready to use. It is particularly suitable for storing and applying small amounts of moisture-sensitive liquids, e.g. primers for adhesive joints.

Abstract: The invention describes a process for carrying out a sewing operation with a sewing machine having a needle feed.In present sewing operations with a sewing machine having needle feed, defective stitches are often formed at the beginning, because the initial threads are not sufficiently clamped in the needle plate as a consequence of the elongated stitch hole. In the new process, the position of the needle prior to the beginning of sewing is displaced into an end zone of the stitch hole for performing a preselected number of initial stitches.
