Title: Method (variants) and device for transmitting signals in a wireless communication system
IPC: H04W84/04
Filed: 2002-11-07
Abstract: A method for controlling the transmission of signals in a communications system uses a polling trigger which prevents a deadlock condition from occurring between a transmitter and receiver. The method includes selecting a protocol data unit from a buffer, determining whether the data unit is located at a last position within a transmission window, and then transmitting polling information with the data unit if the data unit is located at the last position of the transmission window. If the data unit is not in a last position of the transmission window, additional steps of the method include determining whether the data unit is last-stored data unit in a transmission buffer. If so, polling information is transmitted with the data unit. If neither pulling trigger is satisfied, the data unit is transmitted.

Abstract: FIELD: settlement and industrial water supply; devices for preparation of the water for the drinking and industrial water supply systems. 
     SUBSTANCE: the invention is pertaining to the installation of the reagentless treatment of the water for the potable and industrial water supply. The installation contains: the hydrocyclone (1), the water clarifying screen (2), the pump (3), the hydrodynamic impulse generator (4) of the rotor type with the electrical drive (5), the cavitation reactor-cyclone (CRC) (6), two ejectors (7), the skip screen (8). The hydrodynamic impulse generator (4) contains the horizontally arranged cylindrical hollow body, which one has the diametrically located two holes with the accelerating injectors interposed into them. The cylindrical body also contains the cylindrical hollow rotor with two diametrically located similar holes. At that the holes of the accelerating injectors and the holes of the rotor are arranged on the same diametrical axis. At the water entering the accelerating injectors at the average pressure of 0.15 MPa the pressure of the counter pulsing sprays reaches up to 3.2 MPa, which promotes elimination of the spores of the funguses and the bacteria. After passing the hydrodynamic impulse generator the processed water enters the ejectors (7), where it is intensively admixed with the oxygen of the air or ozone, is oxidized and through the tangential fitting pipes enters the cavitation reactor-cyclone (6.) CRC (6) is made in the form of the upright located hollow body (21), which have been fulfilled in the form of the truncated cone mounted with its greatest diameter upward. Inside this body on the same vertical axis there is the accelerating cone and the aligned with it the accelerating cylinder. The being purified water rotating around of the accelerating cylinder goes upward into the collector of the purified water withdrawal, further -into the purified water reservoir and then - to the customer. The solid particles are discarded from the center to the periphery of the CRC body and through the discharge pipe are removed into the sewage. The technical result of the invention is improvement of the quality of the drinking water and profitability at its treatment. 
     EFFECT: the invention ensures the improved quality of the drinking water and profitability at its treatment.

Filed: 1991-06-28
Abstract: An adsorbent in granular or lump form is introduced into a reaction chamber (14) and taken out of it through a grid of channels formed by a multiplicity of separate feed and discharge hoppers (18 and 20). Most of the waste gas is fed into the reaction chamber from one side, so that it spreads out over the whole of that side of the chamber, while a small proportion is fed in through the bulk material distributor cone (17). The flow of waste gas through the reaction chamber (14) is distributed so that the adsorbent in almost all parts of the reaction chamber participates uniformly in the adsorption process. Several reaction chambers with several reaction layers are arranged in series in the gas line. After leaving the first reaction chamber (14), the partly cleaned gas is fed back under the discharge plate (9) in such a way that it passes round, and thus heats, the discharge hoopers (20) and the discharge tubes (21, 22), hence preventing the formation of condensation. The adsorption unit (1) can be used to clean waste gases in refuse-incineration plants, different undesirable constituents being removed separately in different adsorption layers (25, 27 and 26, 28) and further processed.
