Abstract: Abstract of the Disclosure In a disconnectable low-loss optical connection for optical fibers, each fiber in a pair of optical fibers is surrounded by a connector body to the conical frustu? mating end of which is applied a tiny, transparent, flexible index matching dome of silicone rubber or equivalent material.  The connector bodies are held together by mating to each other or to a common alignment receptacle having conically hollow receiving surfaces, so that the fiber ends are aligned and the domes touch and flex completing the optical connection.          The optical fiber connector is suitably manufactured by a method which includes making the connector body around a mandrel or around an optical fiber end in a supporting sleeve in a molding die.          The mandrel or fiber end is compressively centered by means of a deformable annulus.  Then the die is evacuated and a transfer molding compound of polyester or epoxy is forced around the mandrel or the fiber end.          After removal of the molded connector body and extraction of the mandrel, if used, the fiber end is prepared so as to be exposed only near the tip of the connector body.  Then the exposed face of the fiber end and the adjacent portion of the connector body are covered with a transparent dome by dipping an applicator tip in silicone rubber in liquid form, applying a drop from the applicator over the fiber end, and curing the silicone rubber as a dome.        The connector has a variety of applications.          For example, an optical fiber repeater module-to-rack connector is fabricated with guide pins for coarse alignment, and automatic dust cover, crown springs for retaining the connector bodies, and conical alignment receiving surfaces having grooves for self-cleaning.          When the repeater is placed in the rack, domes on the tips of the connector bodies touch and flex completing the optical connection.

Abstract: THRUST VECTORABLE EXHAUST NOZZLE                          Abstract A gas turbine engine flight maneuverable nozzle for installation within an aircraft wing or the like is provided with pivotably connected conver-gent and divergent flaps partially defining an exhaust stream flow path. A third flap, pivotably connected to the divergent flap, partially defines the wing control surface contour. In the cruise and flight maneuver modes, an actua-tion system provides synchronous movement of the convergent and divergent flaps to control, in a predetermined relationship, the areas of the exhaust stream flow path throat and exit. A vectoring actuator, carried by the main actuator, overrides the main actuator in the flight maneuvering mode and causes the divergent flap to pivot downward, thus deflecting the exhaust stream. Simultaneously, the control surface contour defining flap is reposi-tioned to increase the control surface camber thereby increasing lift. Flow separation from the wing control surface is prevented by the effect of super-circulation due to the exhaust stream. Flap actuator forces are reduced by providing the convergent flap with a pressure-balancing feature. Therein one surface of the flap is exposed to pressurized air from the compressor portion of the engine to create a moment about the flap pivot axis which is counter to the moment created by the pressure of the exhaust stream upon the flap exhaust stream flow path defining surface.

Abstract: Abstract of the Disclosure A sensor comprises a layer of an oxygen ion con-ductive solid electrolyte such as stabilized zirconia, two electrode layers of a catalytic metal such as platinum formed porously on both sides of the electro-lyte, only one of them formed on first side of the electrolyte layer being directly exposable to an exhaust gas stream, and a gas passage arranged to allow the exhaust gas to contact the other side of the electro-lyte layer with a time lag behind the contact of the gas stream with the first side.  A fluctuation in the air/fuel ratio of an air-fuel mixture fed to the engine across the stoichiometric ratio can be detected by this sensor since the fluctuation and the aforementioned time lag cause a difference between oxygen partial pressure on one side of the electrolyte layer and that on the other side, resulting in development of an output voltage of the sensor.

Abstract: ABSTRACT OF THE DISCLOSURE       The lower end of a crank from an internal combus-tion engine is pivoted on one side of the center of a small gear which in turn is mounted for rotation to one side of the center of a relatively large drive gear.  A stationary gear is concentric with the drive gear and an idler gear is mounted for rotation to the drive gear and engages the small gear and the stationary gear.  The drive gear engages a take-off gear to transmit power from the piston via the crank and gears.  The gear ratio of the small connecting rod gear and fixed gear is such that the small gear rotates at twice the speed of the large gear.  The connecting pin of the small gear is furthest from the center of the drive gear at top dead center and bottom dead center and nearest to the center at 90° from top dead center and bottom dead center so that when at top dead center, the crank has the highest mechanical advantage and at 90° therefrom, the low-est mechanical advantage.  This means that the piston is slowed down at the center of its stroke thus giving a change of ratio within the engine at each power stroke as well as during the other three strokes.
