Title: Process and apparatus for producing ozone
Inventor: HIRTH MICHAEL DIPL ING DR
IPC: C01B13/11
Filed: 1982-05-27
Abstract: Apart from a high ozone yield, an increase in the efficiency of the production of ozone by electrical discharge becomes increasingly important. It is proposed to increase the efficiency by selectively influencing the effective reaction temperature as a function of the ozone concentration of a volume element during passage through the ozoniser by reducing the electric power delivered to the electrode surface unit along the flow direction of the feed gas. Moreover, there are described ozonisers for carrying out this process in which, on the feed side, provisions in the design of the electrodes (1, 4), of the dielectric (3) and/or the discharge gap (2) for the desired power adjustment have been made. <IMAGE>

Title: Dosimeter for analytically determining pollutants in air
Inventor: WULF GERHARD DIPL CHEM DR RER
IPC: G01N30/00
Filed: 1983-04-11
Abstract: The invention relates to a dosimeter for determining the time-weighted mean of pollutants in the form of gases and vapours. The object of the invention is to provide a device which can be constructed by the user without a manufacturer and which is notable for particularly low cost and high accuracy. The solution according to the invention is to use a generally available, surface-compacted sized paper having known air permeability as diffusion-inhibiting membrane. Situated immediately behind the membrane is active carbon as a collecting medium. A known and readily available sealing frame is added to the membrane and collecting medium to form a dosimeter. The said membrane offers the prerequisite for a short response time, thereby ensuring an excellent integrating mode of operation of the dosimeter. As a result, the true average concentration of pollutants in the air is reproduced with high accuracy.
