摘要:
The invention relates to compounds of formula (I) herein which are reaction products of alkylglycosides with aldehydes and/or diacetals of short-chain alcohols and aldehydes, the acetals obtained being alkoxylated. The invention further relates to a process for producing the above-mentioned compounds and to the use of these compounds for preparing surfactants, especially for industrial detergents and cleaners.
摘要:
The invention concerns amphiphilic compounds of general formula (I), in which R.sup.1 and R.sup.3 each represent a C.sub.1 -C.sub.22 hydrocarbon residue, R.sup.2 is a spacer and X and Y are functional groups. The proposed compounds have at least two hydrophilic and at least two hydrophobic groups based on dicarboxylic acid diamides. The amphiphilic compounds according to the invention are mostly surface-active and are especially suitable for use as emulsifiers, demulsifies, detergents, dispergents and hydrotropic agents in industry and households, for example, in the treatment of metals, ore processing, surface finishing, washing, cleaning, cosmetics, medicine and food processing and preparation.

摘要:
A sleigh having an inflatable body which is wedge-shaped at its forward portion and parallel-sided at its rear portion, the body being subdivided into three inflatable compartments by two spaced longitudinally extending interior webs which slant outwardly relative to one another in their downward directions. The forward ends of the upper edges of the webs are slightly higher than their rear ends. The upper surfaces of the two outer compartments bulge upwardly to a greater extent than the upper surface of the center compartment. Guide foils having longitudinally extending grooves are disposed below the three compartments at the rear end of the body, the foils associated with the outer two compartments being displaced inwardly relative to their respective compartment axes in the unloaded condition of the sleigh.

This invention relates to a process for producing polymerisates by anionic polymerization in an inert reaction medium using conjugated dienes and vinylaromatic compounds in the presence of a catalyst, co-catalyst, and randomizer. Further, the invention relates to the polymerisates produced thereby and their uses.

摘要:
In an electromotively adjustable focusing system for a microscope, a rotatable and axially moveable knob controls both the coarse and fine adjustments of the object stage. The knob is mechanically connected to a tacho-generator producing an output voltage responsive to the direction and amount of rotation of the knob. The knob is also mechanically joined to a switch, which is opened or closed by axial movement of the knob in opposite directions. The closing of the switch causes a focus control circuit to provide to the focusing motor a signal that causes coarse (rapid) focusing. When the switch is opened, however, the motor provides fine adjustment of the object stage.

The invention relates to amphiphilic, non-ionic oligoesters that are free-flowing at an ambient temperature. Said oligoesters are produced by reacting dicarboxylic acid compounds, polyol compounds of water-soluble alkylene oxide addition products and optionally diol compounds. The invention also relates to detergent formulations and concentrates containing the aforementioned oligoesters and the use of oligoesters as additives in detergents, in particular for cleaning hard surfaces.
