Abstract: Method of continuously treating planar textile structures by applying thereto a treatment medium in the form of foam, which includes subsequently applying underpressure to the planar textile structures at a magnitude at which the foam is completely destroyed without any appreciable flow through the material of the planar textile structures.

Abstract: Method of continuously applying a foamed treatment medium to a planar textile structure which includes applying the foam directly to a planar follower guidable synchronously into areal contact with the planar textile structure, and transfering the foam from the planar follower into the planar textile structure by applying vacuum, and apparatus for carrying out the method.

Abstract: Turning machine tool includes a workpiece spindle, a cantilevered longitudinal guide adjacent the workpiece spindle and movable parallel to the rotary axis thereof, at least one tool support mounted on the free end of the cantilevered longitudinal guide and being movable in a horizontal plane perpendicularly to the rotary axis of the workpiece spindle within a work space for the turning machine tool, guide means for the cantilevered longitudinal guide, and a round guide system which includes two transverse guides movable perpendicularly to the rotary axis of the workpiece spindle, the cantilevered longitudinal guide being supported outside the work space through the intermediary of the guide means in the round guide system.

Abstract: A turning machine tool having a workpiece spindle and a tool turret shaft extending parallel thereto and including a transmission and drive means, a single free-standing front plate for supporting and bearing the spindle and the turret shaft, the front plate having a front side at which a working space is provided and a rear side on which the transmission and the drive means are mounted, the transmission having a housing and the spindle and the turret shaft being supported in bearing parts, the transmission housing and the spindle and turret-shaft bearing parts being mutually braced at a spacing from the rear side of the front plate so that in the working space at the front side of the front plate, coordination of a workpiece placed on the spindle to the tools of the turret, is stabilized.

Abstract: Method of producing an entrainer for squeezing or dyeing textile fabric webs with the aid of a foulard which includes inserting a spread-out endless textile web into an annular mold both the web and the annular mold having a periphery and a width corresponding to the periphery and width of the entrainer to be formed and thereafter filling the annular mold with a material that hardens to form a sponge; and endless entrainer produced by the foregoing method.

Abstract: A fluidic oscillator assembly including a fluidic oscillator having an inlet and two outlets, and a piezoelectric element for picking-up frequency oscillations induced in the fluid oscillator, the piezoelectric element being located at and closing one of the outlets of the fluidic oscillator.

Abstract: Device for determining the mixing ratio of binary gases in a mixture thereof by measuring the velocity of sound in the gas mixture, the value of the velocity of sound in the gas mixture determined by the oscillating frequency of a fluidic oscillator, the absolute temperature (T.sub.r) of the gas mixture in the feedback means of the oscillator, a correction factor proportional to the difference between the absolute temperature (T.sub.r) and the predetermined temperature (T.sub.o).

Abstract: Method of dyeing a textile web having a relatively large volume or relief-like construction which includes immersing the web in a dye solution having a dye concentration corresponding to the quantity of liquid to be squeezed from the web in a subsequent dewatering step, passing the web between two absorbent endless entrainer members of a squeeze foulard that are continuously saturated with the dye solution prior to engagement of the endless entrainer members with the web, and squeezing the web in the foulard so as to dewater it to less than substantially 40% moisture with respect to dry weight of the web, then passing the web through an infra-red channel at an adjusted relatively low drying velocity so as to prevent the formation of cloudiness in the dye distribution and drying the web to a final moisture content of at most 5% with respect to dry weight of the web, and subsequently completing the steps of the dyeing process per se.
