Patent BR-0315308-A (BR)
Inventor: AGRAWAL AVNEESH
IPC: H04L1/06
Filed: 2003-10-14
Abstract: A rate adaptive transmission scheme for MIMO systems, which can transmit a variable number of data symbol streams, provide transmit diversity for each data symbol stream, and fully utilize the total transmit power of the system and the full power of each antenna. In one method, at least one data symbol stream is received for transmission from a plurality of antennas. Each data symbol stream is scaled with a respective weight corresponding to the amount of transmit power allocated to that stream. The scaled data symbol stream(s) are multiplied with a transmit basis matrix to provide a plurality of transmit symbol streams for the plurality of antennas.; The transmit basis matrix (e.g., a Walsh-Hadamard matrix or a DFT matrix) is defined such that each data symbol stream is transmitted from all antennas and each transmit symbol stream is transmitted at (or near) the full power for the associated antenna.

Abstract: Liquefying of pulverulent batch materials (e.g., glass batch) is carried out in two stages. The first stage (10) utilizes extended gas/solid contact to heat the materials to an intermediate temperature, and may recover waste heat. The second stage (12) rapidly liquefies the material in a cavity lined with the batch material, and may employ substantially nitrogen-free heat sources. Another aspect involves maintaining a wet condition in the first stage to entrap particulates.

Abstract: Process for the preparation of a sweet wort from a cereal, in which previously mashed cereal flour is mixed with a hydrolyzing substance introducing enzymes to undergo a saccharification treatment. Before mashing, the cereal flour is subjected to a cooking-extrusion at a temperature above 100 DEG  C., by passage continuously in a screw-extrusion machine provided with heating means. The amount of water can be limited to that necessary for the bursting of the starch grain. The extruded cereal is then mashed and mixed with the hydrolyzing substance to undergo saccharification, and the latter can then be effected by infusion. The invention is especially applicable to the preparation of beer or of alcoholic beverages by fermentation of the sweet wort obtained.

Abstract: The motor (1) torque is transmitted through the flange (12) of a hub (11), keyed to the drive-shaft (2), to a plate (14) solidly connected to the torque limiter's input face (15). Flange and plate are connected by three equally spaced balls (16) retained, in holes (18) in the plate and in conical seats (17) in the flange, by a collar (19). A helical spring (20), seated in a grooved nut (21) on the threaded hub end, exerts pressure on the collar, adjustable by rotating the nut. If the torque, though below the limiter setting, exceeds a threshold dependent on this pressure, the balls, expelled from the seats, drive the collar towards the motor. A flange (9) on the collar approaches a proximity sensor (8), operates a contact-initiating an alarm, while torque transmission continues through contact of studs (22) on the plate with the sides of apertures (23) in the flange.
