Title: Fluidized bed furnace
Inventor: BUCHMUELLER HORST
IPC: B01J8/38
Filed: 1989-09-25
Granted: 1993-07-27
Abstract: ABSTRACT   A fluidized bed furnace, used for example in the heating of boilers, has re-introduction of solids and includes a cyclone separator which is connected with its solids exit to a fluidized bed by a siphon and a gravity chute to which a raw coal feeding duct is connected.  An intermediate member connects the exit of the siphon with the gravity chute.  The cross-sectional area of the intermediate member firstly increases, starting on the siphon, and subsequently decreases to the cross-sectional area of the gravity chute.  The raw coal feeding duct is positioned above the enlarged cross-sectional area of the intermediate member.  The enlargement of the intermediate member together with the addition of raw coal to the solids within the intermediate member provides for stratification of the raw coal on top of the solids, thereby preventing caking of the raw coal onto the horizontal walls of the intermediate member and the gravity chute.

Abstract: The filter has a spiral of, or parallel, spaced lengths of, double-ply material whose plies are seamed together along spaced, longitudinal seams to provide an array of side-by-side tubes. The filter support material is highly flexible and has a thickness not greater than 1 mm. Due to the tubular formation, the filter support has an uninterrupted filter zone of substantial area relative to the total area of the filter support; during filtration (when the filter support is under the pressure of the feed) the tube walls bulge out and the filter zone is restrained solely by tensile forces in the filter support itself. Substantial movement of the filter support is possible in the direction at right angles to its face when the pressures on either side of the filter support are equal. The filter support has many applications, but one application is when the filter is connected downstream of an aeration vessel with no intervening vessel, the concentrate outlet of the filter being connected to the aeration vessel for sludge return.

Abstract: The invention relates to a system for transmitting packet data in the air interface of a digital cellular system based on TDMA, Time Division Multiple Access. The mobile terminated logical channels comprise information channels designated for transmitting information and control channels, which can be a fast paging (FP) channel and an acknowledgement (A) channel. The mobile originated logical channels comprise information channels designated for transmitting information and a reservation (R) channel, whereon the mobile station requests the system to reserve a connection for transmitting packet data. According to the invention, for the TDMA frames there is allocated a variable number of time slots for packet transmission, taking into account the symmetricity/asymmetricity of the packet transmission, as well as the total packet transmission demand of the cell. For fast paging (FP), acknowledgement (A) and reservation (R), there can be employed any of the time slots in the frame allocated for packet transmission. It is advantageous that in each time slot, the subscriber's data is subjected to the same interleaving and forward error coding algorithm, so that the respective time slots of consecutive frames form independent logical sub-channels, which are then reserved for one subscriber according to the needs, and to which the subscriber's data is multiplexed at the beginning of the transmission, and wherefrom it is again demultiplexed after the transmission. <IMAGE>
