    摘要: Compounds of the general formula (I) are described: wherein each of R1, R2, R3, R4, R5 and R6 independently represents a substituent selected from the group consisting of hydrogen, methyl, ethyl, n-propyl, and isopropyl; an wherein x represents either 0 or 1. The compounds are useful as fragrances and as added components in fragrance blends. Methods of improving the harmony, emanation, naturalness an staying power of other fragrance ingredients by the addition of such compounds are also described.

    摘要: An electrical surface acoustic wave filter with a wafershaped substrate (1) of monocrystalline, piezoelectric material, in particular lithium niobate, wherein one substrate side supports interdigital transducers (IW 1, IW 2) with metallic electrodes mutually engaging in comblike fashion for the stimulation and coupling out of the surface waves and with plastic and/or elastic damping compounds (10, 11) for the suppression of disturbing wave reflections. The damping compound (10, 11) is applied indirectly or directly to the substrate surface between the active interdigital transducer area "b" and the adjacent long substrate edges (4, 5) of at least one interdigital transducer (IW 1), and that at least in the inactive interdigital transducer areas (a, a).

    摘要: The invention relates to silicic acid ester mixtures containing silicic acid esters of formulae (I) and (II), all ‘R’s being selected, independently of each other, from the following group: H, the straight-chained or branched, saturated or unsaturated, substituted or unsubstituted C1–6-hydrocarbon radicals and fragrance alcohol radicals and biocide alcohol radicals, m taking on values of 1 to 20 and n taking on values from 2 to 100. These esters of oligosilicic acid with fragrance alcohols or biocide alcohols are characterised by a good hydrolysis stability and can also be used in aqueous media or in processes for producing granulates without undergoing excessive losses of activity
