Water soluble trisazo dyestuffs of the formula ##STR1## in which A is 1-amino-8-naphthol-3,6-disulfonic acid or 1-amino-8-naphthol-4,6-disulfonic acid, or a mixture of these two compounds, and B is 1-(3'- or 4'-aminophenyl)-3-methyl-5-pyrazolone, a process for their manufacture by diazotizing component A and coupling it with 3,3'-dihydroxy-diphenylamine to give a monoazo dyestuff, reacting this dyestuff with diazotized component B to give a disazo dyestuff, and converting this dyestuff to the trisazo dyestuff by uniting it with diazotized 4-nitro-4'-amino-diphenylamine-2-sulfonic acid, or by operating as described while, however, changing the sequence of reaction of component B and 4-nitro-4'-amino-diphenylamine-2-sulfonic acid, and use of these dyestuffs for the dyeing of leather and fur.

A container for storing cosmetics or cosmetics accessories includes a main body having an inner storage compartment. An upper cap portion is removably attached to an upper end of the main body and includes a plurality of shelves. Each of the shelves is rotatable to the left or right of a central axis of the container, independently of remaining ones of the shelves, between a closed position and a respective open position. When each of the shelves is in the closed position, shelves are substantially concentric with each other and with a first opening in the upper end of the main body. When the shelves are in the respective open positions, the shelves are not concentric with each other or with the first opening. When the shelves are in the respective open positions, the first opening is revealed to provide access to the inner storage compartment.

An energy-saving method and apparatus for boiling wort in a beer brewing process is easily implemented and managed. The wort (W) to be boiled is supplied to a wort kettle (2) in a batchwise and discontinuous manner, and each batch (C) of wort (W) supplied to the wort kettle (2) is boiled during a boiling phase, whereby the wort vapor (D) escaping during the boiling phase is supplied to a vertical column (10) connected on the steam side to the wort kettle (2), and is rectified in the vertical column.
摘要:
A process of dry dispersal of fine-grained particles on a specimen slide for the purpose of macroscopic or microscopic analysis, and a corresponding instrument for carrying out this process are described. The process permits random, homogeneous distribution of dry particles on a specimen slide in a unilayered, planar distribution, the particles not touching one another at all or only doing so to a negligible extent, i.e. being positioned on the speciment slide without agglomeration. The process steps are: metered input of the fine-grained substance into a sample container; aspiration of the substance by means of a defined partial vacuum, produced in a turbulence chamber, the substance reaching the turbulence chamber via an accelerator tube and then via a distributor tube, and deposition of the accelerated particles on a transparent speciment slide. The device can, in addition, contain a baffle, against which the powder-like sample substance is projected after rushing through the accelerator tube, in order to then pass through a distributor tube, from which the substance falls in deagglomerated form onto the specimen slide. The process and the device can be used for dry dispersal of a great variety of substances in mixed and pure form, for example foods, luxury foods and medicaments or the precursors thereof, mineral or industrial substances, medical or pharmaceutical preparations or precursors thereof, etc. The main area of application is the preparation of powder-like substances for automatic particle analysis.
