Abstract: The invention relates to the use of ethoxylated derivatives of amidoamines corresponding to general formula (I): R1—OC—NR2—[(CH2)n—NR3]m—CO—R4 ??(I) In which R1, R2, R3 and R4 independently of one another represent a hydrogen atom, a branched or unbranched alkyl or alkenyl group containing 5 to 23 carbon atoms or a CO—CH=CH—COOH group and n is a number of 1 to 6 and m is a number of 1 to 8, as an emulsifier in drilling fluids which contain at least one continuous oil phase, an aqueous phase and typical additives.

Abstract: The present application concerns methods for the improvement of the tolerance of certain genetically modified plants towards the use of glyphosate.

Abstract: The invention relates to the use of surfactant mixtures containing alkyl oligoglycosides and alkenyl oligoglycosides (APG) of formula (1), RO-[G]p, in which R represents an alkyl and/or alkenyl radical comprising between 4 and 22 carbon atoms, G represents a sugar radical comprising 5 or 6 carbon atoms and p represents numbers from 1 to 10, mixed with free fatty acids comprising between 6 and 22 C atoms. Preferably, said mixtures are suitable for use as emulsifiers for invert drilling-fluid systems.

Abstract: The invention relates to use of surfactant mixtures in drilling fluids, the mixtures are produced by reacting an aqueous solution of at least one alkyl oligoglycoside and/or alkenyl oligoglycoside with an omega haloacid, or its salts or esters in the presence of an alkali. The mixtures are suitable for use as emulsifiers for invert drilling-fluid systems and improve the filtration characteristics of the systems.

Abstract: A drilling fluid containing an aqueous phase and an oil phase and an ether carboxylic acid of the formula: RO(CH2CH2O)x(CH2CHR1O)yCH2—COOX wherein, R is a saturated or unsaturated, branched or unbranched alkyl or alkenyl group containing 6 to 22 carbon atoms, x is a number from 1 to 20 and y is 0 or a number from 1 to 20, provided that the sum of x and y is at least 1 and at most 25, R1 is an alkyl group containing 1 to 4 carbon atoms and X comprises at least one member selected from the group consisting of a hydrogen atom, monovalent anions and polyvalent anions.

Abstract: The invention relates to a temperature measuring system (1) with a temperature sensor (2), which generates a temperature measurement signal in dependence of a temperature to be measured in accordance with a sensor-specific measurement characteristic curve, and a corrective element (4), which is arranged downstream from the temperature sensor (2) and, from the temperature measurement signal according to a correction characteristic curve, determines a corrected temperature measurement signal that lies in a tolerance range of a specified standard characteristic curve.
