    摘要: Hydrophobic silica aerogels obtainable by reacting a waterglass solution with an acid at a pH of from 7.5 to 11, substantially removing ionic constituents from the resulting silica hydrogels by washing with water or dilute aqueous solutions of inorganic bases, while the pH of the hydrogels is kept in the range from 7.5 to 11, displacing the aqueous phase contained in the hydrogel by an alcohol, and subsequent supercritical drying of the resulting alcogels.

    摘要: In a process for drying microporous, fluid-containing particles, the fluid-containing particles to be dried are fed as a moving bed countercurrently to a drying fluid, the interfacial tension of the fluid being reduced in comparison with the interfacial tension of the fluid at room temperature, at near-critical to supercritical pressure of the fluid, preferably to a value in the range from 0 to {fraction (1/10)}, in particular from 0 to {fraction (1/20)}, of the interfacial tension at room temperature. Furthermore, microporous, three-dimensionally networked particles are prepared by a process comprising preparation of microporous particles containing pore liquid, exchange of the pore liquid in the particles for a fluid and drying of the fluid-containing particles, the exchange and drying being carried out in the moving bed by the countercurrent method.

    摘要: In a process for drying microporous, fluid-containing particles, the heat required for increasing the temperature is supplied by convection by reducing the interfacial tension of the fluid, preferably to 0 to 1/10, in particular to 0 to 1/20, of the interfacial tension of the fluid at room temperature, by appropriately increasing the temperature at from close to the critical pressure to supercritical pressure of the fluid. Furthermore, microporous, three-dimensionally networked particles are prepared by a process in which the drying process is used. In addition, an apparatus is used for carrying out the drying process, the apparatus comprising a pressure container having an inner container and pressure-withstanding outer container and suitable measuring and control apparatuses and pump apparatuses and heat exchangers, the inner container being provided for holding the particles to be dried and a gap being provided between the inner container and the outer container.

    摘要: A method to monitor the current of a handheld power tool (3) operated by a battery (2), by at least one counter (5), includes the following steps: measuring (S1) the electric current (I) drawn from the battery during the operation of the electric tool; incrementing (S2) a reading (Z, Z1, Z2) of the counter (5) by a certain increment (IN) whenever the measured current (I) is higher than a specified upper limit value (G1, G2) during a given counting interval; decrementing (S3) the reading of the counter by a certain decrement (DE) whenever the measured current is lower than the specified upper limit value during the given counting interval; and switching off (S4) the electric tool when the reading (Z, Z1, Z2) of the counter is higher than a specified limit value (T1, T2) for the counter.
