The invention relates to a mixer reactor of the rotor-stator type. This mixer reactor comprises a substantially rotationally symmetric housing which has a distributing chamber, a mixing chamber, a front plate that modifies the cross-section of the housing between these two chambers, and there are separate inlets into the mixing chamber for at least two substances and an outlet for removing the mixed material or product. The inlet for the first substance is provided in the axis of rotation of the mixing chamber. Two or more channels are aligned radially outward from this inlet, and the first substance is transported through these channels and into the mixing chamber. The inlet for the at least second substance is constructed in the form of a plurality of openings in the front plate, these inlet openings being are arranged rotationally symmetrically to the axis of rotation. Each of these inlet openings for the at least second substance has a corresponding pin which can be displaced in the axial direction.

The present invention relates to a reactor (10) and a process for continuous polymerization, where the reactor (10) has an essentially tubular reactor housing (16). The reactor housing (16) has a drive (38) which runs along the geometric central axis (12) in the flow direction (22) and is configured as a central shaft. A rotatably arranged scraper or wiper (36) is provided within the reactor housing (16); the scraper or wiper (36) has at least one scraper or wiper blade (42) to run along an interior side (44) of the reactor housing (16). The rotational movement of the scraper or wiper (36) results in radial mixing of a stream within the reactor housing (16) which dominates gravity effects and, by virtue of shaping of the scrapers or wipers, optionally makes plug flow or a loop flow or backflow within the reactor (10) or else via an additional external pumped circulation system (23) possible. This allows the reaction conditions in the axial direction of the reactor housing (16) to be predicted and individually suitable reaction conditions to be set and controlled along the reactor housing, so that, in particular, a desired molecular weight distribution can be set.

An integrated circuit for an asynchronous serial data transfer comprises a sampler to sample the asynchronous serial data using a sampling clock. A bit length counter determines a bit time by counting a number (m) of predetermined clock cycles, where the bit length terminal variably adjusts the number (m) of clock cycles of the bit length counter.

The invention relates to an integrated circuit arrangement with connection contacts for the serial exchange of data and/or signals with external components and apparatuses and with a control apparatus and/or a serial interface for the clocked receiving of data by means of a signal voltage on such a connection contact, which voltage is modulated between at least one low, one middle and one high voltage state. The control apparatus and/or the interface are designed in such a manner that data is sent in a sending mode via the connection contact in that the switching apparatus, after having received a slope changing in particular from the middle voltage state into in particular the higher or the lower voltage state, pulls the voltage state into the in particular opposite lower or higher voltage state. Furthermore, the invention relates to an apparatus and a process for operating such a circuit arrangement.

A memory device containing data to be protected is integrated with a microprocessor and includes a first and a second memory portion with different accessibilities. The integration of the memory device on the same integrated circuit (IC) or chip as the microprocessor permits a combination of protective hardware and software measures that are not possible with a memory device that is on a different IC than the microprocessor. The first memory portion holds an initialization program that also serves as a boot program during decryption, and the second memory portion holds a user program, for example, a program for decrypting and/or decoding received data. Such data may be, for example, audio data encoded according to the MP3 standard and encrypted with a secret or public password against unauthorized reception.
