Abstract: Abstract Optoelectronic Assembly Including Light Transmissive Window An optoelectronic assembly obtains substan-tially improved coupling efficiency between small core optical fibers and small area detectors and emitters.  The assembly includes a housing contain-ing an active optoelectronic device and a light transmissive window.  The light transmissive window seals the housing and physically protects the device from the environment.  The light trans-missive window is thin, preferably less than 6 mils, and has an index of refraction higher than conventional glass windows, preferably greater than 2, in order to reduce beam spreading between the optical fiber and small area detectors or emitters.  The window material is preferably single crystal GaP.

Abstract: ABSTRACT         There is provided a self-sealing threaded assembly which includes a threaded fastener and a resilient washer.  The threaded fastener has a head with hexagonal faces or other means by which torque can be applied to the head.  An undersurface is provided by the head, and a shoulder portion extends downwardly beneath this under-surface, the shoulder portion having a smaller diameter than the undersurface.  A threaded shank extends downwardly from the shoulder portion, the shank being sized diametrally such that an opening engageable by the threaded shank is too small to accept the shoulder portion.  The resilient washer has a maximum thickness greater than the axial dimension of the shoulder portion, so that when the threaded shank is screwed into an opening in a wall, the shoulder portion will abut the wall and cause the resilient washer to be squeezed between the wall and the undersurface.

Abstract: ABSTRACT OF THE DISCLOSURE    A method of exfoliating the coating of a coated optical fiber, which method has the steps of producing a crack in the coating layer of the optical fiber by bending means, cleaving the coating into a plurality of cleaved strip pieces while longitudinally growing the crack, and then cutting the strip pieces with an advantageous exfoliating tool.  The exfoliating tool thus used is constructed to conveniently cleave the coating layer of the optical fiber and to cut the cleaved strip pieces.          Thus, it does not damage the optical fiber upon exfoliating of the coating layer from the coated optical fiber, and can efficiently exfoliate the coating of the optical fiber.

Abstract: ABSTRACT A magnetically  operated  valve  having  a resilient flat-surfaced valve member cooperating with a valve seat is disclosed.   The resilient member is preferably mounted on an armature in a manner to permit relative motion therebetween to allow the armature to gain a predetermined inertia prior to engaging the resilient member so as to aid in overcoming the pressure differential  across  the resilient member.    Additionally,  the electromagnet thereof acts unevenly on the armature so as to cause a "prying" movement of the resilient member from the valve seat.  The valve may be operated in the normally-opened or the  normally-closed mode.  The armature is provided with a non-magnetic covering or coating,  thereby forming a non-magnetic gap therein.

Abstract: ABSTRACT          An electronic timing circuit to be used in conjunction with photographic cameras using electronic exposure sensing and electrically actuated signal lights responsive to the exposure sensing causes automatic total electrical power shutdown if the camera is left unattended.  No separate manual operation is necessary, the shut-down occurring within approximately half a minute after releasing the exposure button.  Run-down of the camera battery via inadvertent failure of the operator to turn off the system is eliminated. The timer is turned on and system loads are connected in a latched state to the camera battery by partial depression of the exposure button. Adequate ambient illumination of the subject scene causes a photosensor to actuate a green signal light.  Inadequate ambient illumination causes the photosensor to automatically actuate instead a red warning light and a flash tube charging circuit for a built-in flash tube, full charge being evidenced by reappearance of the green light.  If the camera is pointed at a new scene of adequate ambient illumination during or after the charging process, charging stops automatically, and the flash trigger circuit is automatically disabled.  An inexpensive trigger disabling circuit is disclosed.  Two versions of the system are disclosed, one using bipolar comparators and cap-able of operation from a battery voltage of three volts, the other using CMOS comparators and requiring six volts.  Both versions, in the shut-down state, place a total load of less than one microampere on the system battery, resulting in a battery life equal the shelf life if the camera is not used.

The cam following member and first cam track are also operative to release the cam following member from the first cam track and support the first arm on the rocker arm cam follower portion and prevent closing the contacts when the rocker arm cam follower portion is riding on the arcuate segment having the longest radius length.  The cam following member and first cam track further being operative to release the cam following member from the first cam track and close the contact when the rocker arm cam follower portion is riding on the arcuate segment having the second longest radius length.  The rocker arm and second cam track being operative to pivot the rocker arm when the cam follower portion is riding on the arcuate segment having the shortest radius length and the lifter portion engages the lateral projection of the second arm and opens the contacts.  In addition, there is means to reset the timer for subsequent cycling as mentioned above.

Abstract: Abstract Electrically polarizable material (e.g., PVDP film) is poled by applying an electric field across the film.  In the inventive technique, insulation is provided on the surface of the film.   In a typical embodiment, a compliant dielectric annulus insulates the polarized region from the edges of the film.  This substantially eliminates breakdown at the edges of the film, allowing increased poling voltages.  The technique can reduce poling time to typically a few seconds at room temperature, as compared to minutes or hours by prior art techniques, some of which required elevated temperatures.  (FIG. 1)
