Abstract: A method of operating a distributed storage system, the method includes identifying missing chunks of a file. The file is divided into stripes that include data chunks and non-data chunks. The method also includes identifying non-missing chunks available for reconstructing the missing chunks and reconstructing missing data chunks before reconstructing missing non-data chunks using the available non-missing chunks.

Abstract: Organosilicon emulsions of improved quality are prepared batchwise in a circulating loop containing a high shear mixer, while controlling the temperature and pressure within the loop.

Abstract: A process for the preparation of multiphase formulations of organosilicon compounds by (A) formation of a mixture containing organic compound(s) (1) containing at least two aliphatic double bonds and of the general formula R2(CR1═CH2)x,  (1) in which R1 are a hydrogen atom or an alkyl radical having 1 to 6 carbon atoms per radical, R2 is a divalent, trivalent or tetravalent hydrocarbon radical having 1 to 25 carbon atoms per radical; and x denotes 2, 3 or 4 corresponding to the valence of R2; and an organopolysiloxane (2) having on average more than one Si-bonded hydrogen atom per molecule; a catalyst (3) promoting the addition of Si-bonded hydrogen at an aliphatic double bond; an emulsifier (4); and an agent (5) immiscible with (1) and (2); and (B) emulsification of the mixture, with the proviso that the ratio of aliphatic double bond in organic compound (1) to Si-bonded hydrogen in the organopolysiloxane (2) in (A) is such that toluene-soluble siloxane copolymers are obtained.

Abstract: The gas flow in water-containing natural gas wells and natural gas storage wells is improved if a homogeneous phase comprising a water-repellent, solvolysis-resistant active compound is injected into the water-bearing rock.

Abstract: Novel organopolysiloxane compositions comprising (A) organopolysiloxanes which contain at least one SiC-bonded organic radical containing basic nitrogen, where the basic nitrogen is optionally present in part as a salt of a water-soluble organic acid, water-soluble inorganic acid, or water-insoluble organic acid, (B) anionic, cationic, nonionic or amphoteric surfactants, which are in soluble or soluble in (A) (C) substituted or unsubstituted diacrylates and/or oligoacrylates, and optionally, (C′) substituted or unsubstituted acrylates, and (D) water are described.

Abstract: Organosilicon compounds with amino-alkylene oxide functional groups containing amino groups are disclosed.

Abstract: Organosiloxane compounds bearing nitrogen-containing heterocycles, in which the heterocycles are bonded to a silicon atom via divalent radicals containing a unit of the general formula (I) ##STR1## in which E is one of the radicals --O--, --S--, --NR.sup.1 -- or --N.dbd., where R and R.sup.1 are each a C.sub.1 - to C.sub.20 -hydrocarbon radical which is optionally substituted by halogen, amine, ammonium or mercapto groups and may optionally be interrupted by groups chosen from --C(O)--, --C(O)--O--, --C(O)--NR.sup.3 --, --NR.sup.3 --, --O--, --S--, and--N.dbd. is a constituent of a heterocycle,can be used for the treatment of textile fibers, textile sheet materials and leather and as stabilizers in synthetic polymers.

Abstract: A portable dental apparatus. A main housing includes a plurality of wheels mounted therebeneath. A control panel on the main housing includes a variety of controls for operating a plurality of dental tools removably and suspendedly mounted to a holder in turn movably mounted to the main housing. A storage cavity formed in the housing allows storage of the holder and tools when the portable dental apparatus is in a transport state. The tools are connected by a plurality of lines to a plurality of drive and power components located in the interior of the main housing. A lid hingedly mounted atop the control panel may be opened revealing the controls for the tools. An X-ray display screen and amalgamator are provided respectively on the lid and control panel.A modular vacuum unit with a built in cooling fan and thermo protector is also provided. Additionally, the portable dentist apparatus includes an improved pressurized air and water distribution manifold and an improved waste water storage receptacle.
