Abstract: A method in a mobile radio communication system for adapting the system and communication to prevailing traffic and performance requirement. According to the invention a mobile station inserts information on particular codes in its messages transmitted to a base station in response to an invitation message from the base station. The codes indicate whether a message is new or retransmitted and/or message age. The base station receives radio signals in time slots identified in its invitation message and estimates for each time slot based on radio signals received in the time slot whether the time slot is empty or busy, or whether the time slot is empty or correct. For each message received and understood the base station retrieves the code. The retrieved codes and the number of empty/busy/correct slots enable the base station to estimate prevailing system traffic and performance.

This makes it possible to apply with maximum uniformity and without web breaks and wrinkles, immediately successively, a second coating layer during the still wet condition of the first layer where, naturally, again a web guide roll (3) is provided.

Abstract: In a mechanical load brake for a hoist or other lifting device, a one-way device such as a helical wrap spring is fitted over the load brake shaft to automatically adjust for brake disc wear. A tang on the one-way device engages a drive hole in an input gear of the mechanical load brake. The diameter of the drive hole is selected so that the clearance of the tang in the drive hole corresponds to the optimal operating range. The one-way device moves around the shaft as the discs wear maintaining the optimal adjustment for the brake.

Abstract: A wagon for transporting grain and other particulate matter. The wagon is adapted to be attached to a tow vehicle. The wagon has a container which is provided with a forward wall. Within the container is a conduit. The conduit has a part which protrudes outwardly from the container and forwardly from the forward wall. Within the conduit is an auger. Pivotally attached to the part of the conduit which extends outwardly from the forward wall is a conduit extension member. The conduit extension member is pivotally movable to a position extending from the forward wall. Within the conduit extension member is an auger extension member. The auger extension member is operatively connected to the auger when the conduit extension member extends from the forward wall. Thus, a condition is established for discharging grain from the container of the wagon. The conduit extension member is pivotally movable to a position closely adjacent the forward wall.

Abstract: A tray for use with fan-folded paper fed to a printer or other paper processor at high speeds. The tray is adapted to be removably mounted on the open top of a paper carton to allow paper to be fed out of the carton along a predetermined path. The paper has a support plate which is adjacent to an opening defining the path of the paper out of the carton, and a support plate is positioned to allow the fan-folded paper to be returned in stacked relationship on the support plate without operator attention. The paper collected on the tray can be removed by hand at any time.

Abstract: A signal is transmitted to a receiver and is digitalized in signal points (S1). These points are viterbi analyzed in an analyzer with a path memory (PM) having a desired number of states (00, 01, 10, 11) with memory cells (MC). Bit sequences, corresponding to the signal points (S1), are generated and final metric values (m0, m1+g1, m1, m3) for the bit sequences are calculated. In an indicated bit position the best bit sequence, with the smallest final metric value (m2), has a "1", which is the decided bit value. An alternative bit sequence is generated, which is the best bit sequence with the smallest final metric value (m0+g0) under the condition that in the indicated bit position there is bit with the opposite bit value, a "0". The difference between both the final metric values (m0+m0-m2) is a quality factor for the decided bit value "1". The calculation is made in three steps. At a time point metric values (m0, m1, m2, m3) have been calculated for the different states (00, 01, 10, 11).

Abstract: A double-mass flywheel for installation between an internal combustion engine and a transmission. A first flywheel mass associated with the crankshaft of the engine has the shape of a first U which opens radially inward and each of the arms of the U forms a side disk. A second flywheel mass associated with the transmission has the shape of a second U which opens radially outward toward the circumference. The second U engages as a center disk between the two side disks. The two masses are turnable to a limited extent with respect to each other, with the interposition of elastic members which rest at least indirectly on the one side against the first mass and on the other side against the center disk. Damping elements are interposed between the two masses and extend parallel to the elastic members. The center disk is formed of three concentric, partial disks, comprising an inner partial disks and two outer partial disks.
