Abstract: A splice kit is provided for repairing a cable having a central conductor, an insulator surrounding the central conductor, an outer conductive sheath surrounding the insulator, and a jacket surrounding the outer conductive sheath. The splice kit includes a central conductor joint that is electrically conductive and is configured to engage the central conductor of the cable such that the central conductor joint defines a portion of an electrical path of the central conductor. The splice kit also includes a dielectric insert configured to at least partially surround the central conductive joint and the central conductor of the cable, and an outer sheath joint that is electrically conductive and is configured to at least partially surround the dielectric insert. The outer sheath joint is configured to be electrically connected to the outer conductive sheath of the cable such that the outer sheath joint defines a portion of an electrical path of the outer conductive sheath.

Abstract: In a composite electrical circuit protection device, thermal coupling between a planar PPTC element and a planar MOV element is controlled by insertion of a thermal mass material for regulating heat transfer from the MOV element to the PPTC element, such that a PPTC resistor hot zone forms consistently away from the planar major foil electrode confronting the MOV thereby regulating heat transfer from the MOV to the PPTC resistor.

Abstract: A shroud for surrounding a portion of a turbine flow path having improved cooling and durability is disclosed. The shroud includes a plurality of generally axial cooling holes spaced a substantially equal distance apart and a plurality of generally circumferential cooling holes oriented generally perpendicular to the generally axial cooling holes. The generally circumferentially cooling holes are spaced a non-uniform distance apart so as to provide cooling to selected portions of shroud sidewalls to lower shroud operating temperatures and improve shroud durability.

Abstract: There is provided a gas turbine vane with an airfoil cooling circuit incorporating multiple generally radially extending rows of pedestals generally bisected by a plurality of axially extending ribs with the ribs containing a plurality of recessed cavities. The recessed cavities are positioned immediately adjacent pedestals located closest to the ribs such that a cavity passageway is formed to pass sufficient cooling air between the rib and pedestal to increase overall heat transfer and reduce pressure loss of the cooling fluid.

Abstract: A missile guidance system utilizing a single microwave radiometric sensor for both terrain correlation and target homing. Terrain correlation is used to get the missile within the acquisition range of the homing system, and the homing system is used in the terminal phase of operation.

Abstract: A telephone security system for providing an alarm system connected to the telephone. The telephone security system includes a telephone being adapted to be connected to a telephone line and having a housing and a face plate member being removably disposed upon a top of the housing; and also includes a control member being adapted to be connected to the telephone line: and further includes a detection assembly being connected to the ringer-inducer member for sensing an emergency; and also includes a user notification assembly being connected to the telephone for notifying a user of an emergency.

Abstract: An internally cooled airfoil for a gas turbine engine includes a leading edge region, a mid-chord region, a transition region, and a trailing edge region. The mid-chord region has a double wall configuration with the two outer walls and two inner walls. The trailing edge region has a conventional single wall configuration. The transition region has a three wall configuration designed to provide a gradual transition from the four wall configuration to the two wall configuration and to minimize high stresses therein.

Abstract: The heat exchange rate in a passage in indirect heat exchange with a fluid medium is tailored to match its temperature gradient by "short circuiting" the flow in the passage to minimize heat transfer in regions requiring less heat exchange and maximizing heat transfer in regions requiring more heat exchange. The serpentine passageways of an air cooled turbine blade for a gas turbine engine is short circuited to match the temperature profile of the gas path passing by the blade.

Abstract: A film cooling passage through the external wall of a hollow airfoil having in serial flow relation a metering section and a diffusing section, the diffusing section characterized in that it has four inward facing surfaces that define a passage having a generally rectangular cross-section and an outlet over which a hot gas stream flows in a "downstream" direction. One of the surfaces of the diffusing section is generally "downstream" of the other surfaces, and this surface defines a section of a circular cylinder.

Abstract: A switch structure detects acceleration in a preselected direction such as, for example, along the pitch axis of an aircraft. The switch has a spring supported mass urged toward a stable centered position within the switch housing. Acceleration displaces the mass such that it trips a spring wire switch mechanism for controlling such avionic devices as the autopilot system of the aircraft. A pair of solenoid coils are wound around the spring mass system on opposite sides of the centered position of the mass. The switch may be preflight tested by successively energizing the solenoid coils to attract the mass toward the centers of the solenoid fields, thereby artifically displacing the mass against the spring wire switches.
