Patent CA-2405118-C (CA)
Title: Procede pour adapter la durete de la cire de fischer-tropsch par malaxage
Inventor: WITTENBRINK ROBERT JAY
IPC: C10G73/00
Filed: 2001-03-13
Granted: 2011-11-01
Abstract: L'invention concerne un procédé de malaxage de la cire, qui conserve les propriétés désirées d'une cire de Fischer-Tropsch tout en adaptant la dureté de la cire selon une plage désirée. Le procédé utilise un effet synergique entre de la cire vierge dure de Fischer-Tropsch et de la cire de Fischer-Tropsch plus molle, à moitié isomérisée, dans un procédé de malaxage qui permet à l'artisan d'adapter la dureté d'un produit à base de cire selon des plages désirées. Le procédé consiste à passer de la cire de Fischer-Tropsch sur un catalyseur d'hydro-isomérisation dans des conditions préétablies, y compris à des températures relativement douces, telles que des conversions chimiques (p. ex. hydrogénation et isomérisation douce) s'effectuent à un point d'ébullition inférieur à 10 % (hydrocraquage), ce qui empêche de produire de la cire complètement isomérisée. Au moins une partie de la cire isomérisée obtenue est ensuite mélangée avec de la cire vierge dure non traitée.

Inventor: HUANG XINPING
IPC: H04L27/36
Filed: 2003-03-26
Granted: 2010-07-13
Abstract: (57) Abstract: This invention is about a novel estimation technique for generating a predistortion function to compensate for the AM-AM and AM-PM non-linear conversion distortions of non-linear power amplifiers or non-linear circuits. Based on the cumu-lative type of power amplifier output envelope, a non-parametric baseband predistortion function is derived. The non-parametric approach avoids any model mismatch. In addition, the technique does not need to demodulate the input signal. Furthermore, it minimizes the effect of the power amplifier non-linearity and significantly improves the system performance

Abstract: A method and system is provided for splitting a print job lacking page independence into selected job portions wherein the job portions can be independently processed in a plurality of processing nodes into a printer dependent format for printing by a printer. The print job is searched for selected tokens/idioms known to normally generate a fault upon the independent processing if the print job were to be split into the selected job portions that were intended to be handled independently. The selected tokens found in the search are saved. The print job is then split into the selected portions and the tokens are then associated with the split job portions for guaranteeing processing independence during the processing by the processing nodes.
