Abstract: ABSTRACT OF THE DISCLOSURE     The operation of an electronic appliance, such as a casette tape deck, is controlled completely or partially by switch operation.  The appliance includes a memory for storage of control information, setting devices, such as switches, for entering the control information, a memory lock or latch for controlling the operating state of the appliance based on the control information supplied from the memory or from the setting devices to the memory lock, and for locking the appliance into such operating state, a display arrangement adapted for display of the setting information and for display of the information in the memory lock, and a setting change display indicator.  The setting information stored in the memory can be checked by actuating a check switch, which causes the setting information stored in the memory to be displayed without affecting the operating state in which the appliance is locked.  When the operating state is changed by a setting operation while the information previously stored in the memory has been transferred to the memory lock to control the operating state of the appliance, so that the contents of the memory lock (i.e., the operating state in which the appliance is locked) are not coincident with the corresponding information stored in the memory, the fact of such change is displayed on the setting change display indicator.  This notifies an operator that the information is being changed, and assists the operator in avoiding unintentional errors.

Abstract: A METHOD OF RECOVERING OIL FROM A VISCOUS    OIL-CONTAINING SUBSURFACE FORMATION            Abstract Oil is recovered from a viscous oil-containing formation, including a tar sand deposit, by first establishing a fluid communication path 18 in the lower portion of the formation 10 intermediate at least one injection well 12 and a production well 14.          A hydrocarbon solvent having a density less than oil contained in the formation and a viscosity not greater than 1/100 the viscosity of the oil contained in the formation under formation conditions is injected into the communication path 18 and fluids including oil are recovered from the production well 14 until the fluid recovered contains an unfavorable ratio of oil to solvent.  The production well 14 is then shut-in and an additional quantity of the hydrocarbon solvent is injected into the fluid communication path 18, preferably until a total amount of between 0.05 to 0.30 pore volume.  The injection well 12 is then shut-in along with the production well 14 to permit the formation to undergo a soak period for a variable time, preferably for a time of between 2 to 20 days per vertical thickness in feet of oil-containing formation 10.  A driving fluid such as water is then injected into the formation 10 via the injection well 12 and the oil is produced until there is an unfavorable ratio of oil to driving fluid.  During the fluid drive recovery phase, the injection well 12 and production well 14 may be completed to be in fluid communication with the entire portion of the formation to obtain a more uniform displacement of the upgraded formation oil by the driving fluid.

Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus (10) for applying polymerized coatings to can bodies (12) has a means (13) for apply-ing the coating as a liquid containing a polymerizable or polymer coating material in one or more vacuum liquifiable solvents.   The coated can bodies (12) are heated in a confined space (22) a sufficient extent by induction coils (20) to substantially exclude air at entrance (16) to vacuum chamber (18).  Second induction coils (28) heat the can bodies (12) further to flash evaporate the remaining vacuum condensable solvent from the coatings and to cure the coatings.  The solvent vapor is condensed in the vacuum chamber (18) and condensers (68, 72, 76).  A means (50) supplies a sufficient quantity of water at exit (42) from the vacuum chamber (18) to substantially exclude air at the exit (42).  The can bodies (12) vaporize the water and the water vapor excludes the air.  The water vapor is condensed under the vacuum of the chamber (18) by condenser (52).  Because only the vacuum condensable solvent vapor is introduced to the vacuum chamber (18) at entrance 16 and only the water vapor is introduced to the vacuum chamber (18) at the exit (42), and both vapors are condensed in the vacuum, only a small vacuum pump (50) is required to maintain the vacuum in the chamber (18), and the pump is operated only when the vacuum decreases.  Curing the coat-ings under vacuum makes them very high quality over a wide thickness range.
