Title: Method of determining the surface area of metal powders
Inventor: FOERSTER HELMUT DIPL CHEM DR S
IPC: G01N15/08
Filed: 1988-05-19
Abstract: The invention relates to an oxidimetric rapid method for determining the surface area of metal powders and is used for the characterisation or quality control thereof, using, in place of the complicated measurement of the adsorbed inert gas volume, the more rapid and more sensitive determination of the surface oxygen content by activation analysis. The method of the invention is characterised in that a strongly adhering oxide film comprising few atomic layers is produced on the surface of the metal powder under the action of atmospheric oxygen, the excess unbound oxygen is removed after the oxidation is finished by flushing with inert gas, a BET calibration measurement is carried out to determine the specific oxygen covering, the surface oxygen content is determined by activation analysis and the true surface area of the powder is determined therefrom.

Title: Mixing device
Inventor: HOLZER FRANZ DIPL ING
IPC: A62C5/02
Filed: 1988-09-29
Abstract: This is a mixing device for the metered addition of an additive into the extinguishing agent conveyed by a fire-extinguishing pump. It has a measuring and control device (6) which contains a housing (18) through which the conveyed extinguishing agent flows. Arranged in said housing in the flow path of the extinguishing agent is a swivel flap (20) whose respective swivel position depends on the respective throughflow of extinguishing agent. Depending on the swivel position, a greater or lesser throughflow aperture for the extinguishing agent is set. The measuring and control device (6) is operatively connected to a metering device (7) which meters the addition of the additive. Arranged between the swivel flap (20) and the housing (18) containing it is a sealing membrane (31) which seals off the region between the swivel flap (20) and the housing (18) at least for the most part tightly against extinguishing agent except in the region of the throughflow aperture. <IMAGE>

Patent DE-3837432-A1 (DE)
Title: Chemical composition generating oxygen for respirators
Inventor: SMISSEN CARL ERNST VAN DER DR
IPC: C01B13/02
Filed: 1988-11-04
Abstract: It is known to use chemical compositions based on alkali metal peroxides and dioxides as the oxygen source in respirators. The known chemical compositions have the drawback, however, that at the beginning of breathing through the respirator the oxygen generation starts up only very hesitantly. In order to avoid this initial oxygen deficiency, it is proposed, on the basis of the present invention, not to use the peroxides on their own, but in a mixture with strong oxidants such as permanganates and periodates. Mixtures of peroxides with strong oxidants react, under the influence of the humidity from the exhaled air of the person wearing the respirator, to release oxygen, whereas dry mixtures do not react. If such mixtures are granulated and filled into the chemical cartridge of a respirator, sufficient oxygen for breathing is available to the person wearing the respirator right from the beginning of breathing through the respirator.
