摘要： Device which serves to atomize a solid or liquid medium with the aid of a standing ultrasonic wave that is generated between two ultrasonic transmitters. This allows one to tune the standing ultrasonic wave automatically when the temperature of the medium or other process parameters should change.

摘要： An ultrasonic atomizer for liquids comprises a piezoelectric transducer (16) mechanically coupled to an amplitude transformer (20), an atomizing disk (21) mounted to the free end of the amplitude transformer (20), a housing (22) enclosing at least the amplitude transformer (20) and a cap (30) supporting a sieve-like diaphragm (31). The cap (30) is so mounted to the housing (22) that the diaphragm (31) rests on the atomizing disk (21). The cap (30) consists of two mutually concentric cap parts (32, 33) of which one (32) supports the diaphragm (31) and the second (33) serves to mount the entire cap (30) on the housing (22). A spring (36) is so mounted between the two cap parts (32, 33) that the sieve-like diaphragm (31) is held elastically against the atomizing disk (21) and that the opposing force from the spring (36) thereby is transmitted into the second cap part (33) fixed in the housing.Such a liquid-atomizer is characterized in that the diaphragm (31) always rests with a precisely defined prestressing on the atomizing disk (21), whereby operational reliablity heretofore not yet achieved with the previous ultrasonic liquid atomizers is obtained.

摘要： The invention pertains to a method and device for testing the permeability of membrane filters by submitting a wetted membrane filter on its inlet side to a predetermined testing gas pressure within a first closed system and by measuring pressure variation over time within the closed system. The object of the method of the invention is a sensitive testing method permitting permeability, and thus pore size, of a membrane filter to be determined exclusively by measurements performed on the inlet side of the membrane filter. Such measurement is performed by measuring a pressure differential with respect to a reference pressure, or by measuring the quantity of gas per unit of time flowing with respect to a reference pressure system, or else by measuring the pressure differential twice and draining, during the second measurement, a predetermined quantity of gas from the space being tested.
