Patent MX-PA05012173-A (MX)
Title: Mixing device.
Inventor: SCHMALFELD JORG
IPC: B01F7/04
Filed: 2004-04-05
Abstract: The aim of the invention is to improve an existing mixing device in such a manner that for a predetermined reactor length retention time is increased and the material which is to be processed is transported at essentially the same speed irrespective of the radial distance thereof from the rotational axis. As a result, at least one row of blades is arranged on each shaft and each row of blades comprises at least two individual blades and the blades are fixed to the shaft at an incidence angle a in relation to the longitudinal axis of the shaft. The blades are curved in themselves such that the blades form an angle of incidence a on the fixing point of the shaft and an angle of incidence ß on the outer diameter D<SB>A</SB>. By virtue of the fact that a row of individual blades is used instead of a continuous screw, efficient mixing of charging material and coke can be achieved, the angle of incidence is reduced from the inside to the outside and the axial speed of the particles which are to be mixed is evened out on the total cross-section of the reactor, thereby enabling a stop-type flow to be obtained.

Title: Coding and modulation for broadcast and multicast services in a wireless communication system.
Inventor: AGRAWAL AVNEESH
IPC: H04W92/10
Filed: 2005-06-03
Abstract: Techniques for transmitting data in a wireless communication system are described. Physical channels to be sent in a super-frame are identified and allocated time slots in the super-frame. The coding and modulation for each physical channel are selected based on its capacity. The data for each physical channel is selectively encoded based on an outer code rate, e.g., for a Reed-Solomon code, and further encoded based on an inner code rate, e.g., for a Turbo code. The encoded data for each physical channel is mapped to modulation symbols based on a selected modulation scheme. The modulation symbols for each physical channel are further processed (e.g., OFDM modulated) and multiplexed onto the time slots allocated to the physical channel. Data to be sent using another radio technology (e.g., W-CDMA) is also processed and multiplexed onto time slots allocated for this radio technology.
