摘要： The invention relates to a method for determining small quantities of carbon monoxide and nitrogen oxides in gaseous mixtures containing oxygen with the aid of a sensor whose electrical resistance changes at a higher temperature with the carbon monoxide and nitrogen oxide concentrations. It makes use of the fact that, with suitable sensors, on the one hand the resistance-temperature curve of the one of the gases to be determined is clearly different from that of the reference mixture over a broad temperature range (gaseous mixture without the two gases to be determined) and, on the other hand, the resistance-temperature curves of the two gases to be determined approach one another in one part of this temperature range, or coincide, and maintain a clear distance from one another in another part of this temperature range.

摘要： Tin oxide doped with magnesium oxide or niobium pentoxide and prepared as a sintered material is found to be highly sensitive to oxygen partial pressure both in the presence of free oxygen and in the presence of oxidizable gases, such as carbon monoxide or the lower oxides of nitrogen, and even in the presence of mixtures of both, such as in the exhaust gas of an internal combustion engine. The electrical conductivity varies by substantially more than an order of magnitude in response to a change in the oxygen partial pressure of about one-half an order of magnitude. The doped oxides operate as poor catalysts for the oxidation of oxidizable components of the exhaust gases. Chromium oxide doped with tin oxide shows the effect of an excessively good catalysis from the point of view of range of measurement, but is usable to give a sharp indication of the appearance or disappearance of free oxygen in a gas mixture. Zinc oxide doped with aluminum oxide has a conductivity that is good for measuring the content of free oxygen, but is of questionable value in the presence of a substantial concentration of carbon monoxide.

摘要： The present invention provides a catalyst for converting the noxous CO, NO.sub.x and hydrocarbons found in the exhaust gases from internal combustion engines into less harmful gases, and to the method of treating said exhaust gases. The catalyst consists essentially of a solid solution of Fe.sub.2 O.sub.3, Cr.sub.2 O.sub.3, and Fe.sub.3 O.sub.4. The catalyst may be extended on a porous carrier such as aluminum oxide or aluminum silicate. The catalyst is particularly suited for treating the exhaust gas from internal combustion engines of motor vehicles.

摘要： A rotor (11) with a squirrel cage and permanent magnets (19) mounted on and distributed around the circumference of the rotor, including a core stack extending over the entire rotor region with longitudinally continuous rotor slots extending over the length of the core stack. The squirrel cage is constructed with cage bars disposed, and preferably cast, in the rotor slots; short circuit rings connect the cage bars at both end faces of the core; and the radius of the rotor region is reduced by at least the radial thickness of the magnets. The radius of rotor (11) is reduced over the entire length between short circuit rings (17) such that the radial height of cage bars (15, 29) or cage webs (27) connected thereto is reduced. Also an electric motor or a radial pump having such a rotor, and methods of producing or operating such devices.
