Abstract: The compositions for dyeing hair contains at least one 4'- amino-2-halogen-4-[bis-(.beta.-hydroxyethyl)amino]azobenzene. The hair dye compositions according to the invention have a good resistance to acids and provide a wide assortment of natural and fashion shades.

Abstract: A wire coiling apparatus with extraction device for a coiled wire reel (B) with a coiler basket, comprises two concentrical circular rows of basket rods (1, 4) which stand vertically upon a base plate (3). The base plate (3) can be rotatably driven around a stationary vertical bearing. A reel lifting plate (8) is arranged above the base plate (3) between the circular rows of the basket rods (1, 4) which plate can be moved up and down by means of a central lifting rod (7) in the direction of the central axis of the coiler basket. The basket rods of the outer and/or inner circular row are supported in the base plate so as to be rotatable around their longitudinal axis and they can be arrested in at least two rotational positions. The profile of the basket rods is herein designed in such a manner, that the wire contact faces (AF.sub.1, AF.sub.2) of the basket rods facing the central axis of the coiler basket in these different rotational positions, have different spacings (d.sub.1, d.sub.

Abstract: A wire coiling apparatus with a recovery device for a coiled wire reel, including a coiler basket, formed of basket rods arranged on a baseplate which is drivable rotatably around a stationary vertical bearing, and a reel support mandrel that can be lowered upon and lifted off of this baseplate. The reel support mandrel includes a starplate insertable into recesses of the baseplate, and mandrel rods standing on the starplate. The free ends of the mandrel rods are connected with a guide dome and stand between the basket rods of the coiler basket in the inserted position of the reel support mandrel, in which position, the upper free ends of the basket rods are also connectable with the guide dome. The basket rods are fixedly inserted with their lower ends in the baseplate and their outer boundary lines face the wire reel windings, which lines are stressed by the wire reel windings during the coiling process, and extend to be slightly inclined inwards from bottom to top with respect to vertical.

Abstract: Small bundles of elongated profile elements that arrive generally regularly at an intake station wherein the elements are first displaced in a transport direction generally perpendicular to their elongation direction from the intake station to a pickup station. There they are arrested in a pair of groups with the elements closely spaced in their respective groups and the groups widely spaced in the transport direction. The pair of spaced groups is then picked up without substantially changing its spacings and the pair of spaced groups is deposited in a takeoff station while further pairs of spaced groups are formed in the pickup station. These further pairs are then picked up and deposited on top of the respective groups in the takeoff station to form a pair of stacks each constituting a bundle. For nesting the elements it is possible to invert every other pair of spaced groups before depositing same in the takeoff station.

Abstract: 1,3-diamino-4-(2',2',2'-trifluoroethoxy)-benzene, as well as its acid addition salts, are used as new compounds to serve as coupler substance in hair dyeing compositions and yields with known developer substances 1,4-diaminobenzene and 2,5-diaminobenzylalcohol to stable blue tones without any red fraction. Moreover, the new compounds lead to exceptional black tones and ash tones.
