Title: Method and apparatus for performing priority control for cells in output buffer type atm switch
Inventor: IRIE YASUHITO
IPC: H04L47/6275
Filed: 1995-04-27
Granted: 2001-01-02
Abstract: There is provided a method of performing priority control for cells in an output buffer type ATM switch including a switching unit, having a plurality of input ports and a plurality of output ports, for switching/outputting the cells input from the input ports to the output ports, and a plurality of output buffer units, connected to the output ports of the switching unit, for temporarily storing the cells output from the output ports to perform output control of the cells.  A loss quality class and a delay quality class are added to each cell.  A plurality of logical queues for temporarily storing the cells are vertically set in a buffer memory in accordance with the delay quality classes and routing information.  The input cells are selectively written in the logical queues on the basis of the delay quality classes and the routing information added to the cells.  A transition process is performed for all the logical queues to change the delay quality class of each of the logical queues into one of upper and lower classes depending on a cell storage amount in the logical queue.  Upon completion of the transition process, the cells are read from the logical queue having the delay quality class which is a lowest class.

Filed: 1996-12-23
Granted: 2005-10-18
Abstract: The coffee machine for different coffee types requires no preheating ti me and consumes no energy in the standby mode. It essentially comprises a water supply chamber (1), a pump (5), a continuous flow heater (8) for heating the water and a brewing chamber (10) for receiving the coffee (10'). The continuous flow heater (8) has a low heats capacity and can therefore perfor m large temperature changes within a short time. In order to obtain the desired water starting temperature, use is made of a control loop. The unheated parts (9-12) along the water path between the continuous flow heate r (8) and the coffee (10') are so designed that a minimum amount of heat energ y is abstracted from the hot water, but at the same time the parts have an adequate strength.

Abstract: A linear compressor motor comprising a piston assembly and a cylinder assembly mounted together for relative axial movement along an axis by a pair of spiral springs. The piston assembly includes a piston and the cylinder assembly including a cylinder, there being a low clearance between the cylinder and the piston to enable a pumping action to be achieved without seals. Mounted on the exterior of the cylinder is a magnet and associated polepiece. Forming part of the cylinder assembly is a cylindrical housing in which the cylinder itself is mounted by means of a radially-extending flange. The coil for interaction with the magnet is positioned in an annular air gap between the polepiece and the housing.    The coil is wound on a coil holder which is itself mounted on the piston by way of a radially-extending flange. The other radial end of the coil holder is formed with radially extending wings which mount a cylindrical hub which is a clearance fit on the cylinder. The end of the coil holder is castellated to pass across the flange, through suitable apertures in flange. An AC current is applied to the coil to cause relative reciprocatory motion between the piston and cylinder to achieve a pumping action.

Title: Process for producing a reduction gas for reduction of metal ore
Inventor: WURM JOHANN
IPC: C21B13/14
Filed: 1997-07-09
Granted: 2002-11-19
Abstract: In a method for producing a hot CO- and H2-containing reducing gas serving for the reduction of lumpy metal ore, in particular iron ore, the reducing gas is formed in a gasification zone (8) by a gasification of carbon carriers, in particular coal, taking place under the supply of oxygen and subsequently is cooled down to a reducing-gas temperature favorable to the reduction process. In order to produce a thermodynamically more stable reducing gas, the reducing gas by the addition of H2O and/or CO2 - in order to prevent the Boudouard and heterogeneous water-gas reaction and a resultant heating of the reducing gas - is converted to a reducing gas that is thermodynamically more stable at the reducing-gas temperature.

Abstract: A CDMA communication system is disclosed offering a near continuum of data rates up to a maximum rate. The disclosed CDMA communication system increases the data rate variability, without disturbing the orthogonality between users. An increased number of data rates is obtained by time multiplexing the data rates achievable with conventional CDMA systems to provide additional data rates for various multimedia applications. If a user is assigned a specific orthogonal code sequence, such as a Walsh sequence, which permits a maximum data rate, n R, with conventional systems, the user can obtain additional desired data rates up to the maximum rate n R, by time multiplexing the specific orthogonal code set.  Desired bit rates are achievable for applications requiring bit rates that are not an integer multiple of the rates provided by conventional techniques. A fundamental rate of R or "fat pipe" rates of powers-of-two multiples of the fundamental rate can be achieved in a conventional manner. A desired rate up to the maximum "fat pipe" rate is achieved by time multiplexing the codes w k n to achieve rates between R and nR, where w k n, denotes the first nth of the spread spectrum code w k. The transmitter of the present invention achieves a rate conversion to match the appropriate codeword to the appropriate data rate, by employing buffering and reclocking of the data, with time multiplexing of the orthogonal Walsh codes corresponding to the available lower and upper rates. The rate conversion must be synchronized with the selection of the orthogonal Walsh code (corresponding to the lower and upper rates).
