Abstract: ABSTRACT OF THE DISCLOSURE    In a method and apparatus for controlling an AC power supply from a power source to a load having a con-siderably large inductance through electric valve means, the ignition phase angle of the valve means is limited to a value greater than the angle of the power factor.          The limiting value is calculated for each cycle based on the power source voltage and a turn-off period of the valve means in the cycle immediately preceding the aforementioned cycle.

Abstract: ABSTRACT OF THE DISCLOSURE      An arrangement for the emergency cooling of the steam generator unit of a pressurized-water nuclear power plant is disclosed.  Steam 18 passed through a blow-off pipe (ll) into a closed vessel (14) having a water space (12) and a gas space (13). A nest of heat exchanger tubes (15) extends through the water space (12) in a heat transfer relationship to cool the water space.  Steam is dumped under emergency conditions into the vessel via a steam distributor nozzle (18) operatively connected at the end of the blow-off pipe and 18 condensed in the water space.  The steam distributor nozzle 18 arranged essentially below and to the side of the nest of heat exchanger tubes to enhance mixing heat transfer.  The resulting condensate 18 returned to the steam gen-erator as condensate.

Abstract: A B S T R A C T Disclosed is an improved magnetic data transducer having a short gap with improved performance during writing, and substantially unaffected performance during reading.  This is accomplished by placing one or more of the turns of the winding in the gap, occupying a fraction of the gas adjacent the transducing face. This simulates increasing gap reluctance during writing, by causing increased flux fringing.

Abstract: ABSTRACT OF THE DISCLOSURE          A solvent extraction process for tar sands is dis-closed wherein a low boiling solvent having a normal boil-ing point of from 20 to 70°C is used to extract tar sands. Raw tar sands are prepared in feed preparation zone 11, and solvent is mixed with tar sands in dissolution zone 14 the solvent:bitumen weight ratio being maintained at from about 0.51:1 to 2:1.  This mixture is passed to a separation zone in which bitumen and inorganic fines are separated from ex-tracted sand, the separation zone containing sequentially a classifier 17 and countercurrent extraction column 24. The extracted sand is introduced into a first fluid-bed drying zone 27 fluidized by heated solvent vapors, so as to remove unbound solvent from extracted sand while at the same time lowering the water content of the sand to less than about 2 wt.%.  The so-treated sand is then passed into a second fluid-bed drying zone 34 fluidized by a heated inert gas to remove bound solvent.  Recovered solvent is recycled to the dissolution zone.
