Abstract: ABSTRACT OF THE DISCLOSURE      A electrical system for controlling energy output within an enclosed space, such as a motel room, a hotel room, an apartment, a mobile home, a residential home, or an office, including a door switch adapted to be controlled by the opening and closing of the door and a latch switch adapted to be controlled by the operation of a door latch.  The system may control several types of electrical devices, such as a heating and air-conditioning unit, illuminating devices and electrical outlets within the room.           The system is so designed that when the door is closed and latched from the inside all electrical devices will function normally.  When the room is unoccupied, with the door closed and the inside latch unlatched, the electrical devices will be turned off or switched to a low-energy background level.

Abstract: OPTICAL FIBER SPLICING TECHNIQUE     Abstract  of the Disclosure Splicing of one or more pairs of mating optical fibers is facilitated by a loose-fitting optical fiber receiving tube having a uniform interior or cross section with at least one corner; the corner forms a fiber-aligning groove substantially parallel to the longitudinal axis of the tube.  Mating fibers, introduced into opposite ends of the tube, are bent at an angle with respect to the longitudinal  axis sufficient to bias the fibers against the tube's interior surfaces.   In  response to forces generated by the bent fiber the tube rotates to align itself until the mating fiber ends are lodged against the fiber-aligning groove.  This procedure effects transverse alignment of the mating fibers, after which the fibers, still bent, are moved toward each other into abutment.     - i -

Abstract: THERMAL PROCESS FOR RECOVERING VISCOUS PETROLEUM                ABSTRACT OF THE DISCLOSURE          A thermal process for recovering heavy viscous petroleum from a subterranean hydrocarbon formation having low relative permeabilities to water and oil wherein a well bore penetrating the formation and surrounding subterranean strata are initially heated by injecting a heated fluid containing steam into the well and simultaneously venting a portion of the fluid at the surface to lift any condensed liquids forming in the well bore towards the surface to keep the well essentially free of condensed fluids.  The well injection and venting are continued until the well and surrounding subterranean strata are heated sufficiently for the heated fluid to be injected into the formation without condensed liquids forming in the well at a rate greater than the formation can accept.  The heated fluid is then injected directly into the formation at a high injection rate to raise the formation temperature to a desired level, followed by withdrawing the resulting heated petroleum therefrom through the well.

Abstract: FABRICATING PROCESS FOR HIGH STRENGTH, LOW DUCTILITY NICKEL BASE ALLOYS     ABSTRACT OF THE DISCLOSURE    The present invention provides an improved process for fabricating shaped articles from high strength, low ductility nickel base alloys, especially modified IN100.          According to the process, the alloy in prealloyed powdered form is hot isostatically pressed to provide a homogeneous, solid billet.  The pressed, low ductility billet is then isothermally forged to shape in hot dies in a single forging pass which includes an initial slow strain rate stage to effect a minor reduction in thick-ness sufficient to refine the alloy grain structure and place the billet in a temporary condition of low strength and high ductility followed by a high strain rate stage for effecting a major reduction in thickness to the final desired shape while the billet is in said temporary condition.  In the initial slow strain rate stage, the strain rate is selected in relation to the isothermal forging temperature such that the rate is sufficiently slow to prevent cracking of the alloy billet during the initial minor reduction.  In the high strain rate stage, the strain rate employed is generally significantly higher than that used in the initial stage to assure attainment of desirable mechanical properties in the heat treated article.
