    • Optionally metallized azo dyestuffs which in the form of the free acid correspond to the formula ##STR1## wherein K is the radical of a benzene, naphthalene, pyrazolone, pyridone, pyrimidone, acetoacetic acid arylide or aminopyrazole coupling component;A is a non-ionic substituent;X is ##STR2## wherein W is a direct bond or a bridge member to a C atom of the benzene or naphthalene nucleus or the coupling component K;R is hydrogen or C.sub.1 -C.sub.4 -alkyl;B is a direct bond or a bridge member, especially -CO- or -SO.sub.2 -, to a C atom of Q;Q is a reactive radical;m is 0, 1 or 2;n is 0, 1 or 2;p is 0 or 1;q is 0, 1 or 2; andr is 0 or 1;and their use for the dyeing and printing of natural and regenerated cellulose fibre materials such as cotton and rayon, as well as natural and synthetic polyamide fibre materials, for example those of wool, silk, poly-.epsilon.-caprolactam or polycondensate of hexamethylene-diamine and adipic acid. The dyeings obtained, espeically those on cotton and rayon, are distinguished by good fastness properties, especially fastness to wet processing and to light.

    • A method of and apparatus for supplying pulverulent material includes a fluidizing unit which is introduced into a transport container containing the pulverulent material. The fluidizing unit causes suspension or floating of the pulveulent material in the transport container. A suction unit and a discharge unit such as an injector withdraws fluidized pulverulent material and conveys it to the processing device. The fluidizing unit and the discharge unit are preferably combined to a constructional unit which is adjustable relative to the fluidizing unit. Thus, the use of separate powder containers is avoided as the transport container in which the pulverulent material is contained is directly used as a powder container.
    • 用于供应粉状材料的方法和设备包括流入单元,该流化单元被引入含有粉状材料的运输容器中。 流化单元导致冲洗物质在运输容器中的悬浮或浮动。 抽吸单元和诸如喷射器的排出单元退出流化的粉状材料并将其输送到处理装置。 流化单元和排出单元优选地结合到相对于流化单元可调节的结构单元。 因此,作为粉末容器直接使用含有粉状物质的运输容器,因此避免使用分开的粉末容器。
