Abstract: A liquid chemical delivery system automatically delivers viscous chemicals to a number of destinations, such as a number of industrial clothes washers. Several distinct chemicals are pumped, one at a time, into a manifold. The chemical being pumped is mixed with water in the manifold and then transported through a distribution line to its specified destination. By mixing the chemicals with water, viscous chemicals are diluted and delivered using a low pressure delivery system. A single flow meter is used to calibrate all the chemical metering pumps and to recalibrate those pumps periodically, thereby providing accurate chemical metering. The manifold and distribution tube are automatically flushed with water after every chemical delivery so as to reduce corrosion and maintenance costs. In addition, potentially reactive chemicals are kept separate from one another despite the use of only a single distribution line.

Abstract: In the textile industry there is a constant need for processes where the textile material to be treated can be treated in a simple form, for example in rope form instead of in the open-width state, and continuously. According to the invention, this need is met when the textile material is introduced via pressure seal elements into a specially constructed jet dyeing machine, is impregnated there with treating liquor during entry or immediately thereafter and is conveyed further in the machine by means of at least one jet operated by means of a gas stream, the treating agent applied, preferably dye, having advantageously been subjected to fixation in the course of the presence in the gas atmosphere. The necessary physical conditions (pressure, temperature) for this are created by the driving gas. Moreover, in the course of the passage of the textile material it is possible to carry out a further, including a completely different, impregnation.

Abstract: The washing machine functions according to a new principle and contains the washable items, particularly washable textiles, in stacked layers in a mesh cage which is fixed in position at a drum rotatably mounted in a casing. Wash water as well as drying air flows through the preferably stationary or slowly rotating drum containing the washable items, is pumped off at an outlet of the casing, and returns again by way of a recirculation pipe to an inlet of the casing. Intermittent rotation of the drum, for example, by 180.degree., is also possible. In this manner, the wash water or drying air passes through the washable items first from one side and then from the opposite side. All switching procedures are electronically controlled according to a preselected program schedule. The washable items no longer can be damaged by catching on the drum, the wash cycle is more effective and thus shorter than before, and electric energy and chemicals are saved.

Abstract: Textile fabrics are dyed in open widths in a closed, heated environment by spraying a heated dye composition containing a dyestuff dispersed in a non-aqueous, high-boiling solvent, without the dye applicator directly contacting the fabric, directly onto the fabric.

F.) environment and further heated while the sprayed dye dispersion migrates, penetrates thoroughly through the fabric and levels substantially evenly across the width of the fabric. Fabrics are thus simultaneously uniformly dyed and uniformly heatset. Apparatus for conducting the process is also disclosed.
