  • Publication number: 20190338203
    Abstract: Systems and methods are provided for hydroconversion of a heavy oil feed under slurry hydroprocessing conditions and/or solvent assisted hydroprocessing conditions. The systems and methods for slurry hydroconversion can include the use of a configuration that can allow for improved separation of catalyst particles from the slurry hydroprocessing effluent. In addition to allowing for improved catalyst recycle, an amount of fines in the slurry hydroconversion effluent can be reduced or minimized. This can facilitate further processing or handling of any “pitch” generated during the slurry hydroconversion. The systems and methods for solvent assisted hydroprocessing can include processing of a heavy oil feed in conjunction with a high solvency dispersive power crude.

  • Publication number: 20180180141
    Abstract: A continuously variable clutch (CVT) is disclosed which is operable in a first direction to transfer power from a power source to ground engaging members of a vehicle, and in a second direction where the ground engaging members brake and/or drive the engine. The CVT has a braking assembly having a thrust member positioned over a drive clutch shaft and adjacent an outer sheave of the drive clutch. A flanged sleeve is operatively coupled to the drive clutch shaft and generally positioned intermediate the inner and outer sheaves of the drive clutch, with a portion of the flanged sleeve being adjacent the thrust member. The flanged sleeve is fixed relative to the drive clutch shaft when operating in the first direction and is cooperable with the thrust member to move the flanged member axially relative to the drive clutch shaft and towards the inner sheave when operating in the second direction.

  • Patent number: 8950290
    Abstract: A vehicle is described having a transmission driven through a propulsion unit such as an engine, and through a CVT. The transmission is comprised of an input shaft and an output shaft which are coaxially disposed. An idler shaft is driven by the input shaft, and the idler shaft drives the output shaft, through selected gear sets, to provide different gear ratios or drive directions. The CVT also has a fan on the driven side which feeds air through the CVT for cooling. The CVT comprises a drive side clutch and a driven side clutch with the output shaft of the extending through the CVT driven clutch.
