In the production of a gypsum-based porous body of high strength by foaming a gypsum-water mixture, the improvement which comprises including in said mixture about 0.1 to 1 part of a water-soluble aluminum compound per 100 parts by weight of gypsum, calcium oxide or calcium hydroxide in such a quantity that the final mixture has a pH-value in the range of about 10 to 13, a decomposition catalyst, and about 0.5 to 5 parts of hydrogen peroxide, expressed as a 35% solution, per 100 parts by weight of mixture, the ratio of solids to liquid being about 1 : 0.4 - 1.The preferred aluminum compound is aluminum nitrate. The preferred decomposition catalysts are manganese compounds such as manganates or permanganates, e.g. potassium permanganate.

In the production of a gypsum-based porous body of high strength by foaming a gypsum-water mixture containing alkali, hydrogen peroxide and a decomposition catalyst therefor, the improvement which comprises including in said mixture an acid-reacting compound with active hydrogen atoms in a quantity insufficient for complete neutralization of the alkali. The alkali is preferably calcium and/or magnesium oxide and/or hydroxide and the preferred acid-reacting compounds are phosphates and/or sulfates, especially potassium hydrogen phosphates. The acid-reacting compound is employed in an amount sufficient to neutralize about 5 to 50% of the alkali, the final pH being about 12 to 12.5.

A method for producing an organic electronic component comprises, in particular, the following steps: A) producing at least one functional layer stack (10) with the following substeps: A1) providing a flexible first substrate (1), A2) applying at least one organic layer (2) in large-area fashion on the first substrate (1) by means of a coil coating plant (90), and A3) singulating the first substrate (1) with the at least one organic layer (2) into a plurality of functional layer stacks (10); B) providing a second substrate (5), which has a lower flexibility and a higher impermeability with respect to moisture and oxygen than the first substrate (1); and C) applying the at least one of the plurality of the functional layer stacks (10) with a surface (11) of the first substrate (1) remote from the organic layer (2) on the second substrate (5).

The invention relates to a method and device for the continuous polycondensation of polyester material in the solid phase, in particular in the form of partially crystalline granulate. The aim of the invention is to achieve a high product throughput on recrystallising and recondensation of polyester material with a low initial IV. Said aim is achieved, whereby on recrystallisation, a low residence time of 1-10 minutes is achieved, by means of a rapid heating of a thin product layer, followed by an SSP treatment.
摘要:
A real-time system for modeling a turbo-charged engine includes a model configured to estimate various exhaust states such as turbine inlet pressure, turbine outlet pressure, turbine outlet temperature, turbine mass flow rate and waste-gate valve mass flow rate. The model is dependent only on the availability of normal operating values available in a conventionally-configured automotive controller and one or more measured intake side parameters such as ambient pressure, boost pressure, ambient temperature and compressor mass flow rate. The model is constructed to reflect a high-level application of energy conservation between the turbine (generated power) and compressor (absorbed power). A method for the indirect measurement of turbine and waste-gate flow uses turbine inlet and outlet pressure, inlet temperature and engine mass air flow rate measurements. A method for the indirect measurement of turbine efficiency avoids the need for manufacturer's turbine data.

摘要:
An electric device comprising a plurality of operating elements which can be operated by a user. Said device is associated with a status display device, and it also comprises a control logic unit which is coupled to the operating elements in order to detect user operations and which is adjusted. Furthermore, the electric device has an operational state which corresponds to the user operations which are to be adjusted. In a first state, the control logic unit displaces the status display of each operational element, from which it is able to process a user operation, according to an adjusted operational state, and in a second state, said unit displaces the status display of each operational element, whereby it is not possible to process a user operation, according to an adjusted operational state.
