Patent CA-2115211-A1 (CA)
Inventor: AHMADI HAMID
IPC: H04J3/00
Filed: 1994-02-08
Abstract: A Medium Access (MAC) Protocol is utilized for wireless radio access for a plurality of remote stations to a base station on a LAN. The MAC protocol is based on a reservation scheme for user data traffic and a random access technique for control and signalling traffic. There is a time division fixed frame structure in which time is slotted, and time slots are grouped into fixed frames consisting of data and control subframes or periods. The fixed frame structure consists of three periods (A, B, and C) along with their respective headers. The first period, the A period, is the outbound channel which is used exclusively for data transfer from the base station to the remote stations. The following period, the B period, is the inbound channel that is used for contention-free data transfer from the remote stations to the base station. The allocation of the data slots in the A and B periods is performed by the base station. The last period of the frame, designated as the C period, is the control channel used for the transmission of reservation requests and data from the remote stations to the base station in a random-access contention mode using a slotted Aloha protocol. The duration of the three periods may be varied using a movable boundary technique. The base station estimates the number of actively transmitting remote stations utilizing feedback information from the remote stations. This estimate is broadcast to the remote stations as control indicia to control their transmission attempts in the C period, thus yielding high transmission efficiency. <IMAGE>

Title: Biogas reactor for the anaerobic treatment of waste water
Inventor: COENEN HUBERT
IPC: C02F3/28
Filed: 1994-06-17
Abstract: Abstract In UASB-type reactors, the biogas is separated from the rising waste water stream by collection hoods arranged in staggered fashion, in which a zero pressure level is maintained. at which the gas transition takes place.  In cross-section shapes of existing collection hoods, the zero pressure surface is sharply reduced when the water level is high, and the conversion to gas is correspondingly sharply reduces.  Therefore, in accordance with the invention, a rectangular section shape is employed in which the zero pressure surface remains unchanged. The topside of the collection hoods can be formed as a smooth sliding surface in the shape of a roof for the anaerobic sludge sediment.
