Title: Turbo code interleaver using linear congruential sequences
Inventor: ROWITCH DOUGLAS N
IPC: H03M13/29
Filed: 1999-12-03
Abstract: A turbo code interleaver (100) using linear congruential sequences may be employed as a two-dimensional interleaver (16) in a turbo coder (10) that also includes first and second constituent encoders (12, 14). The interleaver (16) and the first encoder (12) are each configured to receive input bits. The first encoder (12) produces output symbols (22, 24) therefrom. The interleaver (16) receives the input bits (20) sequentially by row. A linear congruential sequence recursion algorithm within the interleaver (16) serves to pseudo-randomly rearrange, or shuffle, the bits within each row of the interleaver (16). The bits (26) are then output from the interleaver sequentially by column. The second encoder (14) is configured to receive the interleaved bits from the interleaver. The second encoder (14) produces output symbols (28) therefrom. The two streams of output symbols (22, 24) are multiplexed together, with appropriate puncturing. If desired, the linear congruential recursion sequence can be generated in reverse. Also if desired, a bit reversal technique can be used in the interleaver (16) to rearrange, or shuffle, the rows of the interleaver (16).

Patent CA-2358805-A1 (CA)
Title: Process and apparatus for recovering an oil-enriched product from an oil-bearing material
Inventor: LAVENDER WILLIAM J
IPC: E21C41/26
Filed: 2001-01-24
Abstract: The apparatus and the process are used for recovering an oil-enriched product from oil-bearing material or materials, such as tar sands. The oil-bearing material is mined using a mining equipment and is sent into the apparatus where an optimum amount of oil-enriched product is removed therefrom. Unlike conventional technologies, only a relatively small amount of solvent is used and most of it is recycled back into an earlier stage of the process. The process does not need a tailings pond since the tailings are substantially dewatered at the end of the process. Further, the tailings are deposited in an adjacent area once they come out of the apparatus. This significantly reduces the material handling and transport undertaking, thereby allowing the process and the apparatus to be operated at substantially lower costs compared to conventional technologies.
Patent CA-2361294-A1 (CA)
Inventor: SAIT CHRISTIAN
IPC: C08F2/00
Filed: 2000-03-09
Abstract: L'invention concerne un procédé utilisé pour polymériser, de façon continuelle, de l'isobutène tout en maintenant, à une valeur constante choisie, une propriété P (viscosité, ou masse moléculaire moyenne) du polymère produit. La polymérisation s'effectue dans un réacteur comprenant une phase de réaction d'un liquide en ébullition contenant le monomère et le polymère en formation, lesquels sont en équilibre avec une phase gazeuse à la surface de ladite phase liquide, en incorporant, de façon continue dans le réacteur, un catalyseur et un mélange enrichi en hydrocarbures C4 comprenant le monomère, et en retirant de façon continue du réacteur la phase de réaction du liquide, laquelle est par la suite soumise, de façon continue, à au moins une étape de purification qui a pour but d'isoler le polyisobutène ainsi produit. Le processus comprend l'analyse d'une valeur cible V de la pression partielle piC4 de l'isobutène dans la phase gazeuse du réacteur correspondant à la propriété P, en raison d'une relation empirique établie au préalable entre la propriété P du polyisobutène produit et piC4. Au cours de la polymérisation, piC4 est mesuré et maintenu à une valeur autour de la valeur cible V en intervenant sur le coefficient d'écoulement Qc du catalyseur introduit dans le réacteur et/ou sur le coefficient d'écoulement Qh du mélange enrichi en hydrocarbures C4.

Title: Monocarboxylic acid based antifreeze composition for diesel engines
Inventor: TURCOTTE DAVID E
IPC: C09K5/20
Filed: 2000-02-25
Abstract: The present invention relates to an acid based antifreeze coolant formulation for heavy duty applications such as for diesel engines which may be used for inhibition and prevention erosion and corrosion of aluminum and the corrosion of other metals exposed to an aqueous liquid in automotive coolant systems. The formulation further inhibits mineral scale. It may be packaged as an ethylene glycol based additive for use in new engines or in a concentrated inhibition package as an additive as for reinhibition of used coolant. The combination of a mixture of ethylene or propylene glycol, a monobasic aliphatic organic acid, azoles, low levels of molybdates, a combination of nitrite and/or nitrate salts, polyvinylpyrrolidone, a hydroxide salt, silicates and/or siloxane stabilized silicates with transition metal compounds provide a synergistic protective effect against the cavitation corrosion of aluminum in aqueous liquids reducing the corrosion rate and is effective at relatively low concentrations and varying pH ranges.
