Abstract: Technologies and techniques for operating an operating device for a motor vehicle, in which a first touchscreen user input is received, characterizing a selection of a selection level, wherein a first selection level provides different adjustable driving modes as list participants, and a second selection level provides different adjustable ambience modes as list participants, one arranged by turning a ring element which circumferentially encloses the screen device, a second user input represented about an axis of rotation is received, which characterizes a selection of a list participant from a plurality of list participants in the chosen selection level. Depending on the first user input and/or the second user input, a control signal is provided characterizing a driving mode to be set and/or an ambience mode to be set in which a display of the driving mode and/or the ambience mode is triggered using the screen device.

Abstract: The present invention provides dry mix compositions for use in making gypsum plasters or mortars comprising gypsum, preferably, phosphorous gypsum one or more retarder, and one or more crosslinked cellulose ethers containing polyether groups. The compositions enable the provision of gypsum dry mixes, such as those from phosphorus gypsum, that make gypsum mortars with less stickiness while reducing the amount of cellulose ether in the dry mix.

Abstract: A three-dimensionally printed article is comprised of a hydroxyethyl methylcellulose (HEMC) having a DS of 1.7 to 2.5 and an MS of at least 0.5, wherein DS is the degree of substitution of methoxyl groups and MS is the molar substitution of hydroxyethoxyl groups. The HEMC may advantageously be used as a support material when making a three-dimensionally printed article using a build material such as a different thermoplastic polymer such as a poly(acrylonitrile-butadiene-styrene), polylactic acid, polyethylene and polyprophylene. When the HEMC is a support material it may be easily removed from the build material by contacting the three dimensionally printed article with water, which may be at ambient temperatures and a pH that is neutral or close to neutral.

Abstract: A heat moldable composition which useful for preparing ceramic bodies comprises an inorganic material that sets as a result of baking or sintering, and a hydroxypropyl methylcellulose having a DS of at least 1.4 and an MS of at least 0.6, wherein DS is the degree of substitution of methoxyl groups and MS is the molar substitution of hydroxypropoxyl groups, and a viscosity of up to 80 mPa·s, determined as a 2% by weight solution in water at 20° C., wherein the heat moldable composition comprises at least 40 weight percent of the inorganic material and at least 10 weight percent of the hydroxypropyl methylcellulose, and wherein the composition does not comprise more than 5 weight percent of water, all percentages being based on the total weight of the composition.

Abstract: The present invention provides additives for dry mix or tape joint compound compositions comprising one or more cellulose ether powders containing on its surface one or more hydrophobic alkali swellable emulsion polymer (HASE), preferably, one that is not crosslinked or which comprises, in copolymerized form, no multi-ethylenically unsaturated monomer, and, optionally, an inorganic basic filler. The present invention also provides methods to make the additive comprising kneading at from 50 to 120° C. a wet cellulose ether mixture containing from 50 to 80 wt. % of water with from 0.5 to 25 wt. %, based on total cellulose ether solids, of the hydrophobic alkali swellable emulsion polymer; if desired, adding an inorganic basic filler, and drying and grinding. The additive can be combined with 0.1 to 20 wt. %, based on total cellulose ether solids, of a dry polyacrylamide.

Abstract: The present invention provides additives for dry mix or tape joint compound compositions comprising one or more cellulose ether powders containing on its surface a polymeric additive chosen from polymeric colloidal stabilizers, polymeric fluidizers and combinations thereof. The additive is formed by methods of kneading at from 50 to 120° C. a wet cellulose ether mixture containing from 60 to 80 wt. % of water with from 0.1 to 10 wt. %, based on total cellulose ether solids, of a polymeric additive chosen from polymeric colloidal stabilizers, and polymeric fluidizers, and combinations thereof to form the additive; drying and grinding the additive; and, combining the additive with 0.1 to 20 wt. %, based on total cellulose ether solids, of a dry polyacrylamide.

Abstract: The present invention provides aqueous compositions that are stable after at least a 24 hour period comprising a polysaccharide viscosity modifying additive and more than 60 wt. %, based on the weight of total solids in the compositions of one or more polycarboxylate ether, the compositions comprising an acid chosen from an organic acid having 1 hydroxy group or less, a strong acid containing a single hydrogen, an ascorbic acid, and mixtures thereof, the compositions having a pH of less than the pH of the polycarboxylate ether itself, or from 1.0 to 6.0. The present invention enables stable concentrates of aqueous polycarboxylate ethers and polysaccharide viscosity modifying agents for use in hydraulic binder applications, the compositions having a total solids content of 10 wt. % to as high as 65 wt. %.
