Abstract: A dew point sensor arrangement includes sensing and dry gas source conduits coupled to a dew point sensor. A sensing valve with a sensing valve member couples the sensing conduit to the dew point sensor. A drying valve with a drying valve member couples the dry gas source conduit to the dew point sensor. The sensing valve member fluidly separates the sensing conduit from the dew point sensor in a sensing valve member closed position, the drying valve fluidly couples the dry gas source conduit to the dew point sensor in a drying valve member open position, and the drying valve member moves to the drying valve member open position when the sensing valve member moves to the sensing valve member closed position to dry the dew point sensor using dry gas provided through the dry gas source conduit. Semiconductor processing systems and dew point sensing methods are also described.

Abstract: As-mined oil sand is crushed to −5 inch by a sequentially arranged pair of double roll crushers. The crushed oil sand is fed into a hopper feeding a jet pump. Water or recycled slurry is fed under pressure as motive fluid to the jet pump. The motive fluid jet(s) produced internally by the jet pump are operative to fluidize the oil sand and the components of the slurry mix turbulently in the jet pump's tubular mixer. It is found that the slurry issuing from the jet pump is aerated and largely free of lumps.
