Title: Multistage process for combusting fuel mixtures
Inventor: DALLA BETTA RALPH A
IPC: F23C6/04
Filed: 1991-11-26
Abstract: This invention is a combustion process having a series of stages in which a fuel/oxygen-gas-containing mixture (16, 18) is combusted stepwise using a series of specific catalysts and catalytic structures (figure 2) and, optionally, a final homogeneous combustion zone to produce a combusted gas at a selected temperature preferably between 1050· and 1700 ·C. Depending upon the pressure of operation, there may be two or three discrete catalytic stages (stages 1, 2 and 3). The choice of catalysts and the use of specific structures, including those employing integral heat exchange (44) results in a catalyst and its support which are stable due to their comparatively low temperature, do not deteriorate, and yet the product combustion gas is at a temperature suitable for use in a gas turbine, furnace, boiler, or the like, but has low NOx content. Neither fuel nor air is added to the combustion process except in the initial stage.

Title: Method for the automatic generation of a polling time instants table
Inventor: HARINK JOHANNES H A
IPC: H04M15/00
Filed: 1993-06-16
Abstract: ABSTRACT OF THE DISCLOSURE      Method  for  the  efficient  polling  of  queues  of unknown length, by the generation of a polling table. Using one or more queue characteristic values for the various  queues,  the polling sequence of the various queues is calculated.  Using one or more of said queue characteristic values, the time duration for polling each queue is calculated, taking a margin factor parameter into consideration.  Using the polling times per queue obtained in this way and the switchover time, the rela-tive polling time instants are calculated.   Finally, using a start time parameter, the absolute polling time instants are calculated and written into the polling table.   The polling table can be calculated once at initialisation or else recalculated periodically.     The method is in particular applicable when using a mediation  (2)  to  poll  call  records  from  subscriber exchanges  (1)  for the purpose of providing detailed invoices by a "billing centre" (3).

Title: Transmission system with increased sampling rate detection
Inventor: BERGMANS JOHANNES W M
IPC: H03M13/23
Filed: 1993-07-30
Abstract: ABSTRACT: Transmission system with increased sampling rate detection.   In a data receiver (6) a detection means (10) is used for determining a symbol value from the received signal. For reducing the effect of cyclostationary noise signals, a number of simultaneously operating detectors (12, 14) are used which derive a sequence of symbols from the input signal sampled at different instants. On the basis of a reliability measure simultaneously derived by the detectors, the symbol sequence whose associated reliability measure expresses the greatest reliability is conveyed to the output of the receiver with the aid of selection means.
