  • Patent number: 4153331
    Abstract: A fiber optic interface junction assembly in which an unsheathed end portion of a floating buffer optical fiber is held in perpendicular biased abutment with an optical interface surface by a constrained terminator for such end portion and a continuous coiled portion of the buffered fiber. The interface surface may be active, as in light transmission to the abutting fiber end, or passive, as in reflection of light backwardly into the fiber at such end, according to the particular function needed to be served by the assembly. The end of the optical fiber abutting the interface surface is made square to the fiber axis by cleaving, for efficient optical coupling with such surface, and chamber means are provided for retention of index matching fluid in encirclement of such end, for added assurance of coupling efficiency and protection against contamination by light-obstructing foreign substances that may be present in the surrounding environment.

  • Patent number: 4124272
    Abstract: A rotary fiber optic waveguide coupling. Bared ends of two fiber optic waveguide cable sections are held in mutually-aligned end-to-end adjacent positions in opposite extension along a common rotary axis by a pair of ferrules having central through-openings in which such ends coextend and are bonded in close fit. The ferrules are held in precise axial position by abutment at their inner ends with annular shoulder in a pair of alignment caps mounted in two members movable relatively about such rotary axis. Retaining sleeves screwed into the relatively turnable members cooperate with washer members on the ferrules to obtain such abutment, and the ferrules project through openings in the alignment caps to obtain precise radial positioning. A friction-free rotary bearing interconnects the two relatively turnable members. The bearing is preloaded along the axis of rotation to give precise axial and radial positions of the one turnable member relative to the other.

  • Patent number: 4057104
    Abstract: A streamlined electronic-component-containing pod is mounted on the exterior of a military aircraft in subjection to the airflow past the aircraft during flight. An evaporator in the pod is close coupled thermally to the electronic components for cooling. The outer skin of the pod acts as a condenser for return of liquid refrigerant to the evaporator during normal flight operations. During short-term high-speed dash operation the outer skin of the pod becomes too hot for condensing refrigerant vapor, which then becomes condensed by a heat sink. At this time the refrigerant at the outer skin remaining in the vapor phase acts as thermal insulation.

  • Patent number: 4055906
    Abstract: An automatic self-administered interrogating apparatus that projects a series of film-frame-recorded images onto a rear projection screen. At least many of such images simultaneously present to the viewer both a question and a list of multiple choice answers, any or all of which answers may be selected by actuation of respective response buttons before a new question-answer image is brought into view on the screen. Each question has a serial number that is recorded together with the several answers, and each answer is coded on the basis of branching logic to control the number of film frames to be advanced for presentation of the next question-answer image. A selection device is included for determining which of the several film advancement codes is honored when the choice of answers necessitates such selection.

  • Patent number: 3995944
    Abstract: Apparatus is disclosed for digitally deflecting a line-of-sight (LOS) axis of an energy beam, or an optical LOS axis of an optical train, in each of two mutually orthogonal directions of deflective sweep. The apparatus utilizes a series of mirrors, each of which is independently pivotable about two orthogonally related linear pivot axes. Each of the mirrors doubles the deflection movement of the preceding mirror so that binary values of deflection of the LOS are generated by selective control of the mirrors of the series. Positioning of each mirror is provided by a "four position-two orthogonal axis actuator" which forcibly drives the mirror between any one to any other of four positions consisting of combinations of two pivotal deflection positions about each of two mutually orthogonal linear pivot axes.
