Title: Post-washing of textiles after dyeing with acid dyes - using acid wash liquor to prevent dye extraction
Inventor: SCHUIERER MANFRED
IPC: D06B3/10
Filed: 1977-08-30
Abstract: In the washing of textiles, esp. polyamide or wool carpets, after dyeing with acid dyes, the pH of the wash liquor is maintained at 6. Pref. the pH is controlled at a valve dependent on the textile material being washed, the dye used and the temp. For textiles dyed with weak acid dyes a less acid pH is used in washing, while for those dyed with strong acid dyes a more acid pH is used. The textile is pref. a polyamide velour or wool, esp. uni-dyed materials, dyed by differential-dyeing, pad-steam or cold dyeing processors. Hot-washing can be used to develop the yarn bulk and structure and hence improve its appearance and performance, esp. after cold dyeing, without causing re-diffusion of the dye into the wash liquour and the danger of a non-uniform prod.

Title: Cold shaping tube blank prior to welding - using tool with several sections having changing profiles to ensure continuous guidance
Inventor: HONISCH SIEGFRIED ING GRAD
IPC: B21C37/08
Filed: 1978-02-09
Abstract: The drawing tool is suitable for shaping strips into tubes with wall thickness/dia. ratio of >=1:10. The tool consists of several sections with changing profiles from the strip cross section at the inlet to a tube section at the outlet. Immediately after the inlet section the next profile deviates the edge parts and slightly upwards while the strip edges have a positive guidance along the side surfaces of the tool. At the same time a trough-like indentation is produced in the middle part of the strip as an initial shape for the tube. In the final stage of the shaping process the two edges of the strip are drawn together leaving a suitable gap for the subsequent welding process. In these parts a certain width of the strip remains flat. The amount of this flat width is depending on the wall thickness/dia. ratio and is usually 1/6 of the circumference.

Title: Compressed air purifier - with tank combining cyclone dewatering, cooling, filtering and vapour absorption
Inventor: PRIES HANS
IPC: B01D53/26
Filed: 1978-07-13
Abstract: Compressed air is cooled, purified and dried in a vertical cylindrical tank in which the air first descends in a coiled tube which runs in its top two-thirds in a cooling water jacket. In the lower third, the bulk of the condensate is expelled through perforations by cyclone action and is collected at the bottom for periodical discharge. The air enters an anti-turbulence chamber and ascends through an oil filter into a packing of Raschig rings, followed by a bed of water vapour absorbing tablets which become dissolved. The air finally passes through microfilters before it leaves the tank. This combines all necessary functions in one compact design. The cooling section, for example, can be by-passed by not filling the water jacket. Space is saved and maintenance simplified.
