Apparatus for continuously mechanically removing moisture from web-shaped porous material, includes a drum having a cylinder casing formed with holes therein, the drum being subjectible to negative pressure from within the cylinder casing, a cover layer of absorbent material formed with penetrating capillaries and uniformly disposed over the cylinder casing, means for guiding the web-shaped material about a part of the peripheral surface of the cylinder casing and the cover layer disposed thereon, whereby the moisture to be removed from the material is sucked through the holes and carried off with the aid of the negative pressure, an air-impermeable endless entrainer spaced from the cover layer and engageable with the web-shaped material guided about the part of the peripheral surface of the cylinder casing, for pressing the web-shaped material, in cooperation with the negative pressure from within the cylinder casing, against the cylinder casing covered by the cover layer of absorbent material.

Apparatus for mechanically removing moisture from web-formed material

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.

Fluidic oscillator assembly

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).
