Abstract: A METHOD AND APPARATUS FOR INDEPENDENTLY TRANSMITTING AND RECAPTURING CLOCK RECOVERY BURST AND DC RESTORATION                 SIGNALS IN A MAC SYSTEM            ABSTRACT OF THE DISCLOSURE    The present invention is directed to improving immunity to channel distortions of multiplexed analog component television signals by independently transmitting a clock recovery signal and a DC restoration signal during the horizontal blanking interval of a video line.  More particularly, the clock recovery signal and the DC restoration signal are transmitted on independent lines.  The integrity of the television receiver's system is not compromised if the clock recovery signal is not transmitted on every line. Accordingly, the problems inherent in the prior art are avoided by independently transmitting the clock recovery signal and the DC restoration signal on separate lines during a portion of th horizontal blanking interval of the respective lines.  The clock recovery signal and the DC restoration signal could be transmitted on alternate lines or the clock recovery signal could be sent every Nth line with the DC restoration signal transmitted on lines therebetween.

Abstract: LARGE COMPACT CUTTER ROTARY DRILL BIT UTILIZING             DIRECTED HYDRAULICS FOR EACH CUTTER                 Abstract of the Disclosure An improved rotating drag bit for cutting plastic, sticky, water reactive and shale formations is devised by providing a plurality of large diamond cutters having a circular cutting face in excess of three-quarter inch in diameter. Each large cutter is provided with at least one hydraulic nozzle which in turn provides a directed hydraulic flow at the corresponding cutter face.  The directed hydraulic flow is positioned to apply a force to the chip which tends to peel the chip away from the cutter face.  In addition, the hydraulic flow is positioned with respect to the chip so as to apply an off-center torque to the chip which is used to peel the chip away from the cutter face and toward the gage of the bit.  In particular, the nozzle defines a jet which is characterized by a direction and velocity of hydraulic fluid determined by the jet characteristics.  The core is generally symmetric about its longitudinal axis and has a length along the longitudinal axis and width perpendicular thereto.  The point of the jet most distant from the nozzle defines an impact point of the jet against the chip and cutter face.  The longitudinal axis of the jet is chosen so that at least a portion of the jet  lies between the cutter face and the chip as it is being peeled from the cutter.          Hydraulic removal of the chips is further facilitated by a plurality of junk slots having a contoured compound surface.          The junk slot is characterized by having at least two distinct cross-sectional profiles, namely an asymmetric profile at its lower portion nearest the bit face and a symmetric profile along its upper portion.  The asymmetric and symmetric profiles are connected by a surface providing a smooth hydrodynamic transition.

Inventor: MICHIE MICHAEL M
IPC: C03B37/018
Filed: 1988-07-28
Granted: 1993-10-12
Abstract: Abstract An improved multimode optical fiber having substantially higher bandwidth and lower loss is made by varying the volume of the silica which is deposited in passes of a torch assembly along a substrate tube to form a preform tube which is collapsed to provide a preform from which the optical fiber is drawn. As a result, the thicknesses of the outermost deposited glassy layers in the preform tube are greater and those of the innermost layers are less than those of layers in a preform tube made by prior art MCVD processes. This causes the difference in the index of refraction across each glassy layer to be reduced thereby enhancing the bandwidth and reducing the loss of the drawn optical fiber over those properties of optical fiber drawn from preforms made by prior art MCVD processes. Inasmuch as the inventive process also allows a higher deposition rate than before, it may be used to produce single-mode optical fiber at lower costs than before achieved.
