摘要:
A temperature sensitive paint comprises a binder for forming a polymer matrix, a transition metal complex embedded in the binder and displaying a temperature dependent fluorescence, the fluorescence of the transition metal complex showing a maximum relative temperature sensitivity per Kelvin at a first temperature, and a rare earth complex also embedded in the binder and displaying a temperature dependent fluorescence, the fluorescence of the rare earth complex showing a maximum relative temperature sensitivity per Kelvin at a second temperature. The second temperature is higher than the first temperature by 50 to 150 Kelvin so that the overall temperature range covered by both complexes as temperature probes is extended.

This invention relates to a process and an appliance for drying byproducts from the processing of starch-containing and sugar-containing raw materials, in particular, after their fermentation and distillation, where the byproduct is fractionated in a purification phase with a high liquid proportion and a thick phase, whereby the thick phase is shaped into particles in a conditioning procedure and whereby these particles are dried in a fluidized-bed drying system with a relative gap volume, in the fluidized-bed layer, between 0.5 and 0.92.
摘要:
For monitoring a sensor using differential voltage evaluation for detecting a short circuit to ground and/or to supply voltage UB, a first resistor and a second resistor R1, R2 are assigned to the sensor, a sum voltage is determined from voltages UP, UM at terminals of the sensor, the sum voltage is compared to supply voltage UB, a ratio a of determined sum voltage to supply voltage UB is then calculated, and depending on the value for the ratio a, the occurrence of a shunt at the positive terminal and/or negative terminal of the sensor is detected.

摘要:
A buffer circuit with slow output edges is described. Pulsed higher value currents are driven from one shot timing circuits to inject a pulse of current into the control gate of the buffer's output MOSFET to speed up the beginning of the turning on or the turning off of the output MOSFT. When the beginning and turning on and off is reached lower value current sources continue to drive the gate of the output MOSFET. In one embodiment, one shots are triggered from the rising and falling edges of the input signal. The effect of the higher value current pulses is to reduce the circuit delay through the buffer. Also, the pulse width can be designed as temperature sensitive, and supply voltage sensitive so as to maintain the buffer circuit delay as substantially constant as temperature, supply voltage and process variation occur.
摘要:
In a method for improving cold starting of a catalytically active component in gas generation systems for a mobile fuel cell system, a temporary store is arranged directly in the starting-material gas stream. During cold starting, the temporary store stores gaseous constituents from the gaseous starting material, which constituents cause problems when starting, and releases such constituents (which have been stored during the cold-start phase) again as a result of the heating which takes place as operation of the system continues.
摘要:
A method is disclosed for obtaining and/or immunologically detecting an analyte contained in a gas phase by immunologically binding the analyte to a binding partner thereof contained in a gas- and liquid-permeable first carrier matrix. Said method is characterized in that a) the analyte-containing gas phase is brought into contact with the first carrier matrix (immune adsorber), b) the analyte is bound to the first binding partner which is contained in the first matrix and not bound to the matrix, and c) the complex of analyte and first binding partner and the free first binding partner are eluted from the first matrix, d) the eluted complex or the free first binding partner is determined as a measure for the amount of analyte present.
摘要:
The invention concerns an analytical test element containing an absorbent material with a sample application and detection zone and a blister filled with liquid on a support, wherein the support has a notch within the support surface such that a spike forms there when the support is bent with which the blister can be opened so that liquid escapes and comes into contact with the absorbent material as well as a process for the production of such an analytical test element and a method for determining an analyte by means of such an analytical test element.
