Abstract: The present invention provides greater than 99% pure bis(triorganosilyl)hydroxycarboxylates of the general formulae:R.sub.3 SiO--CHR.sup.1 --COO--SiR.sub.3R.sub.3 SiO--CHR.sup.1 --R.sup.2 COO--SiR.sub.3wherein each R is independently a monovalent straight or branched chain alkyl or alkenyl group having from 1 to about 6 carbon atoms, or an aryl group, R.sup.1 may be hydrogen, a monovalent straight or branched chain alkyl group having from 1 to about 18 carbon atoms, or an aryl group, and R.sup.

Abstract: A method and apparatus for homogenizing and micronizing aerosol formulations. The method includes the steps of homogenizing and micronizing an aerosol formulation at ambient temperature in a closed apparatus where the entire apparatus is maintained under elevated pressure. The apparatus includes a closed loop containing a reaction vessel, a homogenizer and a fluid conduit interconnecting the reaction vessel and the homogenizer. The homogenizer includes an interaction chamber and an intensifier pump. The interaction chamber includes a stream splitter for separating a stream of aerosol formulation components into two streams and an impaction chamber for recombining the stream.

Abstract: Composition for coloring ceramic articles obtained from ceramic mass containing TiO.sub.2 as such, in shades ranging from yellow to orange, consisting of an aqueous or hydroalcoholic solution to be applied to the surface to colored before final firing and containing soluble compounds of chromium/antimony or of chromium/zinc or chromium/zirconium or chromium/manganese mixtures.

C. at a temperature within a range from -50.degree. C. to +70.degree. C. and surface roughness (Ra) after polishing of 3 .ANG.-9 .ANG..

Abstract: Articles of manufacture are provided with a low surface energy, permanently non-stick, non-fouling and ice-phobic surface by a system of coating comprising applying a primary coating having a surface energy of 22-28 dynes/cm.sup.2 comprising a novel polymeric material having non-stick and hardness properties and then applying a top coating having lower surface energy of from about 18-21 dynes/cm.sup.2 comprising a siliconic polymer and interdigitating means to make the top coating permanent, the means preferably comprising a bi- or polyfunctional organic compound adapted to wet the surface of the primary coating and chemically or physically bond thereto and to couple to the siliconic polymeric substance in the top coating. The coated substrates are resistant to marking by graffiti, to adherence by marine fouling organisms, and frozen ice on the surface is easily removed.

Abstract: The invention relates to a device for treatment of drilling mud and cuttings, comprising a screen, a centrifuge (10), a degassing system (6), a discharge system directing the drilling mud back to the active drilling mud system (13, 14), a transport system (17) transporting the cuttings. The screen is a rotating drum (3), and the drum is situated in a mainly enclosed housing (1) with the housing being connected to a vacuum suction system. The solid material discharge from the rotating drum (3) is connected to a downstream centrifuge (10), by a mainly enclosed pipe system (9). A weighing cell (16) for cuttings is connected to the centrifuge (10).
