Abstract: The running up device for an exhaust gas turbo charger works by the alternative feeding of steam or compressed air to the turbine. For this purpose use is made of the separation of an internal and an external feed duct, an assigned control slide valve isolating the internal feed duct and being used to feed in the pressure medium during operation of the running up device. By virtue of this design in the turbine is brought up to a high speed by the fed-in pressure medium with the engine idling, so that the engine has a complete filling and thereby delivers an engine torque. <IMAGE>

Abstract: A three-phase a.c. uninterruptible power supply includes a transformer needing insulation, a single-phase inverter (2), and a cycloconverter (4). The uninterruptible power supply operates to convert a d.c. voltage into a high-frequncy a.c. voltage in the single-phase inverter (2), transmit the output voltage of the single-phase inverter (2) in an insulating state, and convert the output of the transformer into a three-phase voltage having a lower frequency such as 50 or 60 Hz than the frequency of the output voltage of the single-phase inverter (2). It results in allowing the transformer needing insulation to use a high-frequency signal, thereby reducing the transformer itself in size.

Abstract: A computer system firstly comprises a single-chip central processor interfaced to its DRAM main store by a standard DRAM bundle interface. The CPU has cache and memory management unit provisions and a plurality of DMA provisions. By these DMA operations are feasible with respect to a plurality of peripheral control units that are also attached to the DRAM bundle. In this way a separate I/O bus is made superfluous while still allowing fast processor/DRAM dialog. Secondarily, type-two DMA control units may also be connected directly to the bundle while having their DMA control executed locally.

Abstract: A terminal of a packet switched CDMA telecommunication network includes a transceiver. The terminals of network users (Ui,j) communicate with other terminals (U j,i ) via a CDMA channel, and the terminal of each user is assigned a receiver code (r i,j ) and a transmitter code (t i,j ) used by the terminals for encoding packets to the other terminals of the network. To improve the performance of the network, the terminals sense the channel for the presence of the receiver codes (r i,j ) and/or the transmitter codes (t i,j ) at the different stages of the connection establishment, and the transmitting terminal (TER i ) transmits encoded request packets (REQ) and data packets (DAT) to the channel on the basis of the sensing procedure, and the other communicating party, i.e. the receiving terminal (TER j ), receives said encoded packets and transmits encoded acknowledgement packets (ACK) and busy tone packets to the channel.

Abstract: A process is described for the operation of a multiple zone batch treatment system for biological or biophysical treatment of wastewater. The system comprises two or more batch treatment zones (10,12) with wastewater passing sequentially through all treatment zones. After the mix and settle batch steps occur for all zones, influent wastewater flows into the first zone (10) and displaces clarified wastewater in a plug flow mode through each treatment zone and ultimately from the last zone (12). The combining of the decant and fill steps for all or most of the zones provides for shorter cycle times and greater capacity for the system.

Abstract: Disclosed are a printer and a method of switching ribbon tracks of an ink ribbon. The printer uses an ink ribbon (5) having a plurality of ribbon tracks (T₁, T₂, T₃, T₄) of the same color and properly switches the ribbon tracks (T₁, T₂, T₃, T₄) from one to another in a printing operation. This ribbon-track switching method switches the ribbon tracks (T₁, T₂, T₃, T₄) from one to another when a printing page is changed or an equivalent operation is executed. It is therefore possible to suppress a decrease in printing density to thereby prolong the service life of the ink-ribbon cartridge. Since the ribbon tracks (T₁, T₂, T₃, T₄) are switched from one to another when a printing page is changed or an equivalent operation is executed, thus inhibiting the switching of the ribbon tracks (T₁, T₂, T₃, T₄) on the same page, the printing density on the same page becomes even and the printing quality can be improved.

Abstract: The engine has first and second intake ports (102, 103) for one cylinder (combustion chamber) (104). The intake ports (102, 103) are formed in a cylinder head (101) and extend substantially parallel to each other. Downstream ends (107, 105) of the first and second ports (102, 103) open to a combustion chamber defined in the cylinder upon a compression stroke. The first intake port (102) is a helical port to generate and supply a first swirl into the combustion chamber (104). The second intake port (103) has a recess (109) in its wall near its downstream end (105) to reverse a flow direction of the air in the second intake port (103) so as to generate and supply a second swirl into the combustion chamber (104). The recess (109) in the second intake port (103) reverses the air flow direction before the intake air in the second intake port (103) enters the combustion chamber (104), so that the second swirl flows in the same direction as the first swirl in the combustion chamber (104). Therefore, a single strong swirl (S) is obtained in the combustion chamber (104).
