Abstract: A method for manufacturing a sensor. The sensor includes a sensing element and a housing, the housing including an interior space, which is accessible through a housing opening, and the sensing element being situated in the interior space and being designed to detect a property and/or a composition of an ambient medium of the sensor. The method includes filling the interior space with a protective medium through the housing opening, the protective medium being designed to transfer the property and/or the composition of the ambient medium to the sensing element; fixing a preferably flexible diaphragm at or in the housing opening preferably for sealing the housing opening, the diaphragm including at least one diaphragm opening; and sealing the at least one diaphragm opening. A sensor, which is manufactured according to this method, is also described.

Abstract: The invention relates to a method and a device (100) which are provided for the oxidative treatment of a liquid phase and/or a gas phase and/or a solid phase. According to the invention, ozone and at least one component, which is provided by the ozonization of at least one olefin, is used for the treatment. The method and the device can, for example, be used for waste water treatment.

Abstract: An apparatus for disinfecting an interior of a generally closed container having an opening has an elongated housing fittable through the opening, having a wall forming a reaction chamber, and having an inner end and an outer end longitudinally flanking the chamber. Thus when the outer end is tilted to the opening, the inner end is in the interior of the container. An ozone generator is provided in the chamber. A plurality of openings in the wall of the housing at the inner end conduct ozone from the chamber out into the interior of the container.

Abstract: The invention is directed to a procedure for disinfecting a toilet appliance in which water for flushing a toilet (1) is introduced from a cistern (9) into a flush pipe (7) and from there into the interior of the toilet (1). The water is channeled through an ozone generator (11), where it is enriched with ozone and flows on as ozone water containing dissolved ozone and ozone gas bubbles before it enters the cistern (9). The cistern (9) is filled with the ozone water up to a pre-determined water level (35) and the ozone gas bubbles in the ozone water rise into the gas space above the water level (35) so that when the cistern (9) is filled up to the pre-determined water level (35), a piston effect is exerted by the rising water level (35) which guides the ozone gas into the flush pipe (7) and from there into the interior of the toilet (1).

Abstract: The invention is concerned with a device of destroying ozone in gases by employing a recuperative plate heat exchanger (1) and an integrated electrical heating element (19, 21). The recuperative plate heat exchanger (1) is equipped with at least two planes, a preheating plane (11) and a recooling plane (13), whereby the flow direction of the gas treated in the recooling plane (13) is reversed relative to the ozone-containing gas in the preheating plane (11). Preferably, the flow directions of the preheating plane (11) and the recooling plane (13) cross over. The electrical heating element (19, 21) is situated in a reaction chamber (3) and heats up the ozone-containing gas preheated in the heat-exchanger up to temperatures of 350° C. or more, and thus destroys the ozone within the gas almost to completion. The plate heat exchanger (1) works almost without pressure losses.

Abstract: A process and apparatus for measuring the concentration of gases in a medium are provided in which the radiation absorption of the gas in the medium is determined with the aid of a sample measurement and reference measurement. The medium with the gas is continuously passed through a measuring cell, and a reference medium not containing the measured gas is continuously passed through a reference cell. Both cells are alternately brought into the optical path between a lamp and a photoreceiver. The results of the absorption measurement in the measuring cell and the reference cell are divided. The concentration of a gas in a liquid, or ozone in water, can be measured by passing the liquid through an exchange material in a packed tower, through which a reference gas stream is passed in counterflow manner. An exchange of the measured gas occurs from the liquid stream to the reference gas stream.
