Abstract: Provided is a process for catalytically reforming a hydrocarbon feedstock using a highly sulfur sensitive catalyst. The process comprises contacting the hydrocarbon in a reaction zone, with the hydrocarbon feed and catalyst flowing in opposite directions. Once the catalyst has passed through the reaction zone, it is then passed to a regeneration zone for regeneration. The process eliminates the need of passing the hydrocarbon feed through a sulfur sorber prior to entry into the reaction zone, as the spent catalyst which is leaving the reaction zone for regeneration acts as a sulfur sorber and removes the sulfur from the feed entering the reaction zone.

Abstract: The present invention provides a silo unloader which combines the advantages of both a single auger unloader and a double auger unloader and substantially eliminates the disadvantages of both, to create a silo unloader that is very efficient and effective. Only a portion of the unloader's auger arms has dual augers working therewith while the remaining portion has a single auger. The dual auger functionality is positioned at the end of the auger where most freezing and compaction occurs, thus creating a very aggressive auger at this point. Additionally, the blower of the present silo unloader is positioned at an angle above the augers. This allows for the use of an efficient closed bottom blower in a double auger system while also allowing the placement of the two augers substantially next to each other. By placing the two augers in close proximity to one another reduces the overall width of the auger arm, thus creating a more efficient auger arm.

Abstract: The invention concerns a method and a device for coding an audio signal by "forward" and "backward" LPC analysis, the coding being produced by "forward " LPC filtering for non-stationary zones and on a synthetic signal based on "backward" LPC filtering for stationary zones. For each current LPC block (B n) (10), the degree of stationarity of the digital audio signal is determined (11), and a "forward" or "backward" LPC analysis selection value is established (12) based on a decision function, according to the stationarity  parameter. A "forward" or "backward" LPC analysis criterion is applied (13) to the analysis selection value to produce the audio signal coding before proceeding to the next LPC block. The invention is applicable to mobile radiotelephony, to the production, memorisation of audio recordings, to the transmission by satellite and wideband telephony.
