Abstract: This application relates to intermediates useful for the preparation of fiber-reactive dyes, said intermediates having the formulae ##STR1## in which B is a --(CH.sub.2).sub.n -- or --O--(CH.sub.2).sub.n -- radical, where n is 1 to 6; Q is selected from the group consisting of hydrogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, halogen, carboxyl and sulfo; and A is an amino substituent of the formula ##STR2## and Z and Z', independently of one another, are .beta.-sulfatoethyl, .beta.-thiosulfatoethyl, .beta.-phosphatoethyl, .beta.-acyloxyethyl, .beta.-haloethyl or vinyl.

Abstract: The invention relates to a process for the preparation of concentrated storage-stable aqueous solutions of yellow azo- and azoxystilbene dyes which are obtained by self-condensation of 4-nitrotoluene-2-sulfonic acid in the presence of an alkali metal hydroxide, by converting the sparingly soluble alkali metal salt of the dye into a water-soluble ammonium salt by double cation exchange via a lipophilic ammonium salt, which process comprises carrying out the double ion exchange in a two-phase system of nitrobenzene/water and using, for the first ion exchange a di- or trialkylamine containing a total of 12 to 40 carbon atoms and, for the second ion exchange, a mono-, di- or trialkanolamine containing 2 to 4 carbon atoms in each alkyl moiety.The concentrated storage-stable dye solutions so obtained are particularly suitable for dyeing paper.

Abstract: An apparatus for supporting an object includes a member having a plurality of connected bent portions. The portions include pair of generally horizontally extending, spaced apart, generally parallel lower legs each having a free end and an opposite end connected a lower end of one of a pair of vertically extending first uprights each connected at an upper end to a generally horizontally extending first cross beam. A pair of generally horizontally extending arms are each connected at one end to one of the first uprights between the upper and lower ends and at an opposite end to a lower end of one of a pair of generally vertically extending second uprights each connected at an upper end to a generally horizontally extending second cross beam. A pair of upper legs each have one end connected to one of the first uprights and extend generally horizontally parallel to and spaced above the lower legs a distance generally corresponding to a thickness of carpet in a vehicle.

Abstract: The reactive dyes are useful, in particular, for dyeing or printing cellulose-containing fiber materials by the cold pad-batch method and produce, with a high dyeing yield, dyeings and prints having good fastness properties.

Abstract: A two-pole inductorless monolithic crystal filter device comprising first and second spaced electrodes mounted on one face of the device, third and fourth spaced electrodes mounted on the opposite face of the device in superimposed relationship with the first and second electrodes, a first capacitor coupled between the first and fourth electrodes, means electrically coupling the second and third electrodes, and a second capacitor coupling the second and third electrodes to a point of reference potential with the first electrode and point of reference potential being designated as input terminals and the fourth electrode and point of reference potential being designated as output terminals.
