Abstract: A wafer carrier includes a base including a generally planar bottom surface and a top surface that includes a plurality of platforms extending above the top surface. The wafer carrier includes a thermal cover defining a plurality of pockets. The thermal cover is configured to be coupled to the base by at least one fastener and the plurality of pockets are arranged such that each pocket of the plurality of pockets is aligned with a corresponding platform of the plurality of the platforms when the thermal cover is supported by a plurality of first pedestals that extend from the top surface of the base. A plurality of second pedestals are located along the plurality of platforms for supporting the one or more wafers, wherein each platform includes at least one second pedestal that extends from a top surface of the platform for supporting one wafer.

Abstract: A high temperature paraffinic froth treatment (HTPFT) process utilizes an unheated flash vessel as a first stage of solvent recovery in a paraffinic solvent recovery unit (PSRU) to minimize asphaltene precipitation and fouling in subsequent stages of solvent recovery. The HTPFT may utilize a heat pump circuit for heat integration in the PSRU where a first stage of solvent recovery is at a lower temperature than a second stage of solvent recovery. Froth entering froth separation vessels can be heated using heat in a tailings stream using a heat pump. Froth separation vessels used to separate froth for collecting a bitumen-containing overflow utilize a collector pot and conventional feedwell combination, or a combination of a collection ring and nozzle arrangement for reducing disturbance in the vessel and improving collection of the overflow.

Abstract: Improved cathode cans, for use in electrochemical cells. Broadly, the cans comprise corrosion-susceptible core layers, and protective metal layers such as nickel overlying the core layer and disposed between the core layer and a, preferably electroless plated, duplex coating layer such as nickel, which overlies severed edges of the core layer, and also typically overlies the protective metal layers. Thickness of the duplex coating layer is less, preferably no more than 75%, of the thickness of the protective metal layer. Combined thickness of the protective metal layer and duplex coating layer is preferably about 75 microinches (0.002 mm) to 200 microinches (0.005 mm). Thickness of the duplex coating layer alone is preferably about 25 microinches (0.0006 mm) to 100 microinches (0.0025 mm). Combined thickness of the protective metal layer and the duplex coating layer is preferably at least 1.25 times, up to no more than 2 times, thickness of the protective metal layer.
