摘要： A process for the coating of the flow channels of a cylindrical, honeycomb form catalyst carrier with a dispersion coating through filling of the vertically oriented flow channels with a fill quantity of the coating dispersion through the bottom face of the catalyst carrier and subsequent downward emptying and clearance extraction of the flow channels, as well as drying and calcination of the catalyst carrier, by the following steps:a) filling of the flow channels with a fill quantity that is about 10% greater than the empty volume of the flow channels, so that the coating dispersion goes over the upper face of the catalyst carrier after completion of the filling cycle,b) removal of the excess coating dispersion at the top before emptying of the flow channels andc) emptying and clearance extraction of the flow channels through an extraction impulse, which is generated by connection of a vacuum tank with the bottom face of the catalyst carrier,whereby the time between the beginning of the fill cycle and the end of the emptying and clearance extraction amounts to no more than 5 seconds.

摘要： Calibration of sensors of the type used for the cutaneous determination of blood oxygen and carbon dioxide levels is facilitated by providing separate sensor units, alternatively and removably connectable to a calibration device and to the measuring devices with which they are used for such determinations. The sensor units contain, in addition to a sensor electrode, a data memory in which is stored calibration data generated when the sensor unit is connected to the calibration device. The calibration device can provide a plurality of calibration stations, each capable of supplying a standard gas to a connected sensor and, in response to signals from the sensor exposed to the standard gas, generating data signals representing the calibration of the sensor, which signals are transmitted to the data memory of the sensor unit. Upon connection of the sensor unit to the measuring device, the calibration data from the data memory of the sensor unit are used as a calibration base for measurements by the sensor.

摘要： There is described a method and device for measurement of the specific density of a gaseous or liquid medium, whereby a pulsed acoustic signal is injected into the measured medium by means of a transmitting transducer, the signal is detected by a receiver transducer, after passing over a measured path, whereupon the acoustic impedance Z is automatically determined in an analytical device by comparison of a curve for the currently measured received signal with reference curves, predetermined for various values of the acoustic impedances stored for each value of the acoustic impedance, whereby the propagation speed c of the acoustic signal in the medium is determined and the density p of the medium is calculated as the quotient from the acoustic impedance Z and the propagation speed c. The method is preferably of application to an ultrasound mass flow measurement device and hence has the advantage that no additional density sensor is required, nevertheless permitting a robust and precise measurement of density.

摘要： A fuel cell system that employs a purge valve, an accumulator and a bleed valve for selectively purging and bleeding anode exhaust gas. When the purge valve is opened, the anode exhaust gas purges to the accumulator where it is collected. The bleed valve provides a controlled release of the anode exhaust gas from the accumulator that allows the concentration of hydrogen bled from the accumulator to remain below its combustible limit. In one embodiment, the purged anode exhaust gas is combined with the cathode exhaust gas and released to atmosphere. In another embodiment, the purged anode exhaust gas is combined with a cathode input gas. In another embodiment, the purged anode exhaust gas is combined with an anode input gas.

摘要： This galvanic electrode of a flow sensor of an electromagnetic flowmeter for measuring the volumetric flow rate of an electrically conductive liquid flowing in a measuring tube is practically absolutely fluid-tight inserted in the wall of the measuring tube and has a highly constant wetting surface. The electrode comprises a shank having a first portion which is fitted fluid-tightly in a hole in the wall, an end face and a second portion having a smaller diameter than the hole and the first portion. A wetting surface formed by the end face and a second portion of the electrode shank. This second portion forms a gap between the surface of the hole. The gap is sufficiently wide and the surface of the hole has a low surface tension so that the liquid will penetrate into and fill the gap, and the wetting surface will remain constant under all operating conditions of the flowmeter.

摘要： A reinforcement-containing metal-matrix composite material is formed by dispersing pieces of reinforcement material throughout a melt of a bulk-solidifying amorphous metal and solidifying the mixture at a sufficiently high rate that the solid metal matrix is amorphous. Dispersing is typically accomplished either by melting the metal and mixing the pieces of reinforcement material into the melt, or by providing a mass of pieces of the reinforcement material and infiltration of the molten amorphous metal into the mass. The metal preferably has a composition of about that of a eutectic composition, and most preferably has a composition, in atomic percent, of from about 45 to about 67 percent total of zirconium plus titanium, from about 10 to about 35 percent beryllium, and from about 10 to about 38 percent total of copper plus nickel.
