Abstract: HIGH VERTICAL CONFORMANCE STEAM DRIVE OIL RECOVERY METHOD          (D#77,093-F) ABSTRACT OF THE DISCLOSURE         The vertical or both vertical and horizontal conformance of a steam drive process is improved by employ-ing one or more infill wells between the injection well and production well, the infill well being in fluid com-munication with the bottom half or less of the formation.          In the first step, petroleum is recovered from the infill well after oil production at the production well has pro-ceeded to a predetermined point.  After water cut of fluids being produced from the infill well reaches a predetermined value, the production well is converted from a production well to an injection well and steam is injected into the converted well while continuing recovering fluids from the infill well.  When one infill well is employed in a more or less aligned arrangment between injection and production wells, the vertical conformance is improved.  When one or more infill wells are utilized in a pattern comprising one or more injectors and one or more producers, both horizontal and vertical conformance is improved.     I

Abstract: OVEN DOOR HINGE                    ABSTRACT OF THE DISCLOSURE           A pair of spring-loaded oven door hinge mechanisms, mounted on a domestic range body and located at the lower corners of a counterbalancing oven door lock in a partially open position upon removal of the oven door to preclude acci-dental tripping of the non-counterbalanced hinge mechanisms. Reinstallation of the counterbalancing oven door unlocks the spring-loaded hinge mechanisms to permit normal oven door movement between open and closed positions.  Each hinge mech-anism includes a fixed roller normally engageable with a hinge blade projection to provide a broil position detent mechanism.  The fixed roller snaps into a deep recess or notch in a movable hinge blade upon removal of the oven door to provide positive locking of the hinge blade to maintain the associated hinge mechanism in a partially open position, thereby facilitating oven door reinstallation.

Abstract: Abstract Of The Disclosure A method and apparatus for controlling electrode drive speed in a consumable electrode furnace.  The electrode drive speed is regulated at a base speed computed from measured changes in physical characteristics of the electrode or ingot, such as changes in weight, as the melt proceeds.  The base speed also takes into consideration the known geometry of the electrode, the furnace mold or crucible, the density of the ingot material, and the speed of movement of the bottom of the ingot if any.  This base speed is increased or decreased by a trim speed determined from measurement of an electrical phe-nomenon associated with the consumable electrode process, which electrical phenomenon has a relatively long term value related to the distance between the bottom surface of the electrode and the top surface of the ingot.

Abstract: MOLTEN TIN REPROCESSING OF SPENT NUCLEAR FUEL ELEMENTS                 Abstract of the Disclosure A method and apparatus for reprocessing spent nuclear fuel is described.  Within a containment vessel, a solid plug of tin and nitride precipitates supports a circulating bath of liquid tin therein.  Spent nuclear fuel is immersed in the liquid tin under an atmosphere of nitrogen, resulting in the formation of nitride precipitates.  The layer of liquid tin and nitride precipitates which interfaces the plug is solidified and integrated with the plug.  Part of the plug is melted, removing nitride precipitates from the containment vessel, while a portion of the plug remains solidified to support the liquid tin and nitride precipitates remaining in the containment vessel.  The process is practiced numerous times until substantially all of the precipitated nitrides are removed from the containment vessel.
