摘要:
Substituted olefins of the formula (I) ##STR1## are prepared by reaction of a compound of the formula (II) ##STR2## with a compound of the formula (III)R--CH--CH.sub.2in the presence of an organic and/or inorganic palladium salt as a catalyst using water and/or an alcohol as a solvent, the substituents and indices being defined in the disclosure.
摘要:
A hydraulically curable composition, in particular for the production of concrete, mortar, screed, or render having improved freeze-thaw resistance, as well as a process for producing the composition. The composition includes the constituents cement, additional constituents, and organofunctional silicon compounds, and optionally aggregates and admixtures. The composition also contains the additional constituents fly ash and silica dust, in each case independently based on the weight of cement, in an amount of from 1 to 25% by weight and the organofunctional silicon compounds in an amount of from 0.1 to 5% by weight based on the weight of cement.
摘要:
The present invention relates to dye mixtures which comprise at least one dye of the formula (I), at least one dye of the formula (II) and optionally at least one dye of the formula (III) and/or optionally at least one dye of the formula (IV) in which D1 to D7, R201 to R203, R0, R* and R**, T, M, v and f are as defined in claim 1, to dyes of the formula (II), to processes for their preparation, and to their use for dyeing and printing hydroxyl- and carboxamido-containing materials.
摘要:
A method for access control to installation control systems of wind energy installations. The method includes receiving a requested user name and a requested password, wherein authorizations and checking information are coded in the requested password. The method further includes decoding the authorizations and the checking information from the requested password, checking the requested user name on the basis of the decoded checking information, checking the decoded authorizations if the check of the requested user name on the basis of the decoded checking information has a positive result, and allowing access to an installation control system of a wind energy installation when the decoded authorizations are sufficient. A wind energy installation for implementing the method includes an installation control system and a decoding unit.
摘要:
Reactive dye mixtures comprising one or more dyes of the general formula (I), one or more dyes of the general formula (II) and optionally one or more dyes of the general formula (III) where D1, D2, D3, D4, D5, R0, R*, R**, T, b, f, v, and M are as defined in claim 1, the dyes of the general formulae (I)-(III) containing at least one fiber-reactive group of the formula —SO2-Z or -Z2, are prepared and used for dyeing hydroxyl- and/or carboxamido-containing fiber material.
摘要:
The present invention relates to a dye mixture which comprises at least one dye of the general formula (I) and at least one dye of the general formula (II) in which D1, D2, W1, W2, Y1, Y2, R1 to R6, M, m and n are defined as indicated in claim 1, to processes for preparing them, to their use, and to inks comprising them for digital printing.

摘要:
An apparatus for the performance of the SNMS process, having a separate ion source, a sample holder, a system for the production of a radio-frequency plasma and a mass analyzer, in which the ion source and the mass analyzer are disposed side by side on the same side of the chamber provided for the radio-frequency plasma, and in which the sample mounted on the sample holder is situated within the chamber provided for the radio-frequency plasma. This apparatus can be used not only for the performance of the two kinds of SNMS operation (DMB and SBM) but also secondary ion mass spectroscopy (SIMS) under optimum spatial conditions.
摘要:
A method is disclosed, including identifying a preamble in a frame, where the preamble has a preamble length 1. M data items received in succession are stored. The m data items once divided into n portions, where the data items in each portion have respectively been received at successive times and where m and n are natural numbers and the following applies to m and n: m>n, m>1, n>1. The n portions are respectively correlated to the expected values to form component correlation results. Delaying the component correlation results, with at least two component correlation results being delayed by different lengths. The method also includes combining the delayed component correlation results to form a total correlation value. The total correlation value is used to determine whether the m received data items contain the preamble of a frame.
