A method for making a setting accelerator, especially for binders based on calcium sulfate, wherein gypsum together with at least one polycarboxylate is subjected to a dry grinding. The system can provide increased availability, reduced internal latencies, and reduced data processing and transfer. The parametric array of audio transducers operates by employing the nonlinear interaction between high frequency sound components and the propagation medium to generate at least one highly directional beam of lower frequency sounds within the propagation medium. Since the volume of the phase change region is not changed, an electric current level required for rewriting is constant. A DC control module receives a plurality of the codewords from the data dependent scrambler, selectively inverts selected ones of the plurality of codewords to reduce a difference between a total number of zeroes and total number of ones in the plurality of codewords and outputs an encoded data stream. The hybrid gas generator contains a pyrotechnic gas generator produced using a body, which contains an igniter and which is provided with first and second ends, and a flexible element, which contains a pyrotechnic charge and which is attached to the second end of the body; and a pressurized gas reservoir attached to the pyrotechnic gas generator at the first end of the body.
