Title: Synchronization and gain control circuit
Inventor: HARFORD JACK R
IPC: H04N5/53
Filed: 1979-08-07
Granted: 1982-08-31
Abstract: RCA 71,594 Abstract A circuit is provided for developing a television synchronization signal and an automatic gain control (AGC) signal.  A composite video signal is coupled to the input of a D.C. threshold noise inverter which inverts impulse noise above a predetermined threshold level.  The inverted noise signal and a delayed video signal are coupled to a peak detecting sync separator which generates a noise-free sync signal.  The noise-free sync signal is coupled to a latching circuit, where it is combined with a horizontal retrace (flyback) signal to produce an AGC keying signal of constant pulse width.  An AGC circuit is keyed by the AGC keying signal to generate an AGC control signal from the composite video signal.  The time constant of the peak detecting sync separator performs the dual functions of tracking the sync signal of the composite video signal and preventing lockout of the keyed AGC circuit.

Abstract: L. M. Borsuk-8 METHOD AND APPARATUS FOR DETECTING OPTIMUM ALIGNMENT     OF OPTICAL FIBERS IN A CONNECTOR ARRANGEMENT           .     ABSTRACT OF THE DISCLOSURE       A method and apparatus for detecting the lateral align-ment of abutting optical fibers in a connector arrangement. A connector assembly having eccentric sleeves for effecting lat-eral alignment is shown.  A light beam is introduced at an angle through the cladding of an optical fiber adjacent to its interface surface within one connector half.  The light beam is launched into the fiber cladding at a plurality of angles using a light scattering bead of resin.  The outside diameter of the ferrule assembly is concentric with the optical fiber and the connector shell externally, once the lateral alignment is effected.  A termination fixture includes an objective lens which projects a magnified image of the optical fiber interface surface onto an aperture plate having an opening or window therein substantially the same diameter as the magnified optical fiber core, transmits substantially only light emitted from the cladding interface surface.  A light-to-electric signal trans-ducer (photo-diode for example) detects the illuminated and magnified image of the optical fiber cladding,  A light inten-sity null detected by the transducer is indicative of proper alignment of the optical fiber with respect to the outside dia-meter of the connector shell and ferrule assembly.

Abstract: ABSTRACT OF THE DISCLOSURE A hardware interrupt apparatus for assigning the microprogrammed control system to the highest priority hardware interrupt requesting service.  In a microprogrammed control system having at least one hardware interrupt, the presence of a hardware interrupt request will cause the interruption of the currently executing microprogram at the end of the current microinstruction.  The address of the next microinstruction in the interrupted microprogram is saved in a hardware interrupt return address register and the next microinstruction address is generated as a function of the particular hardware interrupt to be serviced.  A microprogram dedicated to servicing the particular hardware interrupt is then entered at the hardware interrupt generated next microinstruction address.  Logic is provided within each microinstruction to inhibit hardware interrupts.  Logic is provided within each microinstruction to indicate that the address of the next microinstruction should be taken from the hardware interrupt return address register, thereby allowing for the resumption of the interrupted microprogram.  The hardware interrupt apparatus is further organized such that the entry to a second hard-ware interrupt service microprogram can be made upon the completion of a first hardware interrupt service micro-program without having to return to the original micro-program interrupted by the first hardware interrupt.  Upon completion of the second hardware interrupt microprogram service routine, return can be made to the original micro-program interrupted by the first hardware interrupt.

Abstract: ABSTRACT       A bowling bag for one or two bowling balls, as desired.  The bag includes a pair of hard shell similarly shaped bag sections each of a generally cup-shaped con-figuration having open sides mounted in confronting relation defining a cavity for receiving a bowling ball or balls. Hinge means joins the bag sections in assembly together along respective lower edges of the sections.          Handle means is cooperable with the sections for trans-porting the same.  Latch means joins the bag sections along upper margins of the bag sections.  Ball mounting means for securely positioning one or two bowling balls is disposed for coacting with the bowling ball inside the cavity defined by the sections.  The ball mounting means comprises three sets of longitudinally spaced sockets supported by opposed walls of the sections.  The sets of spaced sockets on the bag sections are positioned vertical-ly above the lower edges a sufficient distance for enabling opposite sides of a bowling ball to be positioned within anyone of the three sets of longitudinally spaced sockets to inhibit movement of the ball when so engaged while the bag sections are in a closed position relative to one another.  The sockets are so located to enable the ball to be engaged upon the lower edges of the bag sections when mounted inside of the cavity defined by the closed bag sections.  The handle means is positioned in a cen-tered position with respect to the sockets so that the load of the bowling ball when carried in a centermost of the sockets can be uniformly balanced relative to the handle means to facilitate ready transport of the ball. The handle means is so positioned with respect to opposite endmost of the longitudinally spaced sockets enabling bowling balls to be carried and supported in side-by-side relation within the endmost sockets so that the load of the bowling balls can be uniformly balanced with respect to the sections when the bag is transported by the handle means.

Abstract: Abstract A method of producing large objects from rapidly quenched non-equilibrium powders in which the powder is first slowly precompacted to a predetermined density without causing any substantial temperature rise. The powder is then rapidly compacted by a shock wave having a short rise time. In this way thin surface regions on the particles are rapidly brought to melting to cause interwelding of the particles. These thin surface regions are then rapidly quenched by conduction of heat to the interior of the particles. Because of the very rapid heat-ing and quenching, in the order of a few microseconds, degradation of the material is avoided.
