A powdery ore is preheated with hot air in a preheating furnace (2) and sent into a fluidized-bed reaction furnace (1). Iron oxide particles contained in the gas discharged from the furnace (2) are recovered in a dust collector (3) and are reduced in a reduction furnace (4). The reduced iron particles are fed into the passage leading to the reaction furnace (1), where they act as a catalyst for accelerating iron carbide formation.

 Appl.No PCT/US1995/002946 Applicant AMOCO CORPORATION Inventor WARREN, Tommy, M.
A rotary drill bit (22) for drilling a curved subterranean borehole (26). In one embodiment, the drill bit comprises a side portion (40), a plurality of cutting elements (44) that produce a lateral force on the drill bit (22) in response to the rotation of the drill bit in the borehole, and bearing means (48). The bearing means is located on the side portion (40) of the drill bit (22) and contacts the borehole wall (28) during drilling to receive a reactive force that is from the borehole, that is in response to the lateral force and that is directed to a location adjacent to the uphole end of the side portion of the drill bit (22). The reactive force and the lateral force form a downhole-moment that is about the drill bit and that is opposed by an uphole-moment having a force component that is directed at the flexible joint (186). The uphole end of the bearing means (48) is located relatively close to the cutting elements (44) such that the magnitude of the downhole-moment and the magnitude of the uphole-moment are minimized.

 Appl.No PCT/GB1998/002726 Applicant ATLANTIC RICHFIELD COMPANY Inventor CRANE, Steven, D.
A method for producing a heavy crude oil from a subterranean formation through a wellbore and converting the heavy crude oil into a product distillate hydrocarbon stream and at least one of heat, steam, electricity and synthesis gas by separating distillable components of the heavy crude oil by distillation and solvent deasphalting and converting the asphaltic residual portion of the heavy crude oil in a fluidized bed to at least one of heat, steam, electricity or synthesis gas. In one embodiment, the heavy crude is diluted and the crude oil/diluent mixture is transported to a market location where the crude oil is subsequently converted. The method also produces diluent hydrocarbons useful as a separate product, a distillable hydrocarbon stream or in the production and transportation of the heavy crude oil.

 Appl.No PCT/FR2002/002242 Applicant TECHNIP FRANCE Inventor PARADOWSKI, Henri
A method for the liquifaction and denitrogenation of natural gas, a system for carrying out said method, and gases obtained by said separation. The invention relates to a method for the liquefaction and denitrogenation of natural gas (1) containing nitrogen, wherein said natural gas (1) is cooled, liquefied and separated into a first head fraction (9), which is relatively more volatile and enriched with nitrogen, and a first foot fraction (15). The method is characterized in that the first head fraction (9) is cooled and liquefied, separated into a second head fraction (11) which is relatively more volatile and which provides gaseous nitrogen (29), and a second foot fraction (12) which is re-treated, also characterized in that the first foot fraction (15) is cooled in order to provide liquefied natural gas which is essentially devoid of nitrogen (24). Other embodiments are also disclosed.

A process for the extraction of bitumen from bitumen froth generated from tar sands is presented. The deaerated bitumen froth (12) produced by deaerator (11) is fed to primary mixer (13) where it is mixed with secondary settler overflow produced from the secondary settler (22), containing a large proportion of diluted bitumen and solvent, fed through suitable conduit (15). During mixing in primary mixer (13), the secondary settler overflow (15), containing diluted bitumen and solvent, solvates a portion of the bitumen contained in the bitumen froth and precipitates a portion of the contained asphaltenes.

 Appl.No PCT/RU2000/000187 Applicant PELEVIN, Vadim Nikolaevich Inventor PELEVIN, Vadim Nikolaevich
The invention can be used for protecting human life from dangerous and especially dangerous phenomena (hurricanes, typhoons) provoked by cyclones and also for regulating the volume of simultaneous precipitation events, being important for the agricultural sector (controlling tropical cyclones). The weakening of cyclones (hurricanes, typhoons) by preventing the destructive effect thereof is carried out by creating an atmospheric motion wherein certain areas thereof are influenced upon. In order to identify the troposphere impact areas, a value of available potential energy in the troposphere is calculated and the results are compared with a rating value of the available potential energy which produces a breakdown wind velocity dangerous for the environment. If a measured value of the available potential energy reaches the rating value of the available potential energy, one or several impact areas are selected for transformation of the available potential energy into kinetic energy, thereby forming a cyclone having a power which dos not exceed a destructive level.
