Abstract: The invention describes a multistage process, for producing particles with an average particle size from 50 nm to 1000 nm in a very effective and gentle manner, wherein the solid substance (active substance) is dissolved in a solvent, this liquid containing the solid substance (active substance) in dissolved form is then frozen very rapidly, the solvent/solvents used are optionally removed from the frozen matrix obtained in a (freeze-)drying process (lyophilization) or the frozen matrix is further processed directly, the solid matrix (frozen or lyophilized) is dispersed in an external phase, a liquid medium, which can be water, a mixture of water with water-miscible liquids or a non-aqueous liquid, and the resulting dispersion is then immediately exposed to high shear and/or cavitation forces, and the forces applied result in stabilization or comminution of the resulting particles in the nanometer range.

Abstract: A circuit arrangement for the time-delayed startup of electronic modules (20) connected to a module carrier (1) comprises a comparator (28) provided with a reference voltage applied thereto and an operating voltage which is applied via charging capacitors (35 to 38) with different capacitances. The terminals (4c-f to 19c-f) for the charging capacitors are integrated in different combinations into the terminals (4a,b to 19a,b) on the module carrier for the operating voltage. The startup time-delay is determined on the basis of the different time intervals resulting from the different values of the capacitances and lasting until a voltage exceeding the reference voltage is achieved, whereupon the respective electronic module is connected to the voltage source by means of the comparator in a time-delayed manner.

Abstract: A circuit arrangement with a multi-wire line for supplying current to a sensor and for emitting a signal that corresponds to a measured value to an evaluation module via a signal line. To eliminate measuring errors caused by short circuits, first and second resistors, with the second resistor provided with a current tap, and a transistor, which is connected to a clock-pulse generator that bridges the first resistor in a clocked manner, are connected in series to the signal emission line. A comparator for comparing the values obtained via the resistors in the successive switching positions of the transistor and for emitting a short-circuit error message to the evaluation module, if the measured values differ in the successive clock pulses, is connected downstream of the resistors.
