  • Patent number: 4873320
    Abstract: Water-soluble dyes which contain one or two fiber-reactive groups of the formula ##STR1## in which each R is a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, it being possible for both R to have a meaning which is identical to or different from one another, Y is the vinyl group or a group of the general formula --CH.sub.2 --CH.sub.2 --X in which X represents a substituent which can be eliminated as an anion, and m represents the number 2 or 3. These novel dyes can be used to dye hydroxy and/or carboxamide group-containing materials in particular fiber-materials, such as, in particular, cellulose fiber materials, in fast shades.

  • Patent number: 4745184
    Abstract: Method for preparation of dispersible, water-soluble polygalactomannans and polyglactomannan derivatives by crosslinking with borate ions, in which the polygalactomannan-containing endosperm of legumes is allowed to soak in an aqueous alkaline solution of a material containing borate ions in which the concentration of the borate ions, expressed as borax, is between 0.001 and 0.09 wt. % and the hydroxyl ion concentration, expressed as NaOH, is between 0.2 and 10 wt. % of the polygalactomannan and after taking up the solution, the cell structure of the splits is mechanically destroyed using high shear forces in a flaking, crushing or extruder process and then the product of the process is dried and ground in known fashion.

  • Patent number: 4312194
    Abstract: In a flat-knitting machine having a needle bed and a plurality of carriages which orbit the needle bed in a predetermined path, the needles which are to knit in accordance with a predetermined pattern are selected by advancing electromechanical controllers in a path other than the predetermined path and transmitting activating signals to them via trailing cables from a stationary control unit when the controllers move in the same direction as and parallel to the carriages.
