Abstract: ABSTRACT OF THE DISCLOSURE           Ghost phenomenon on a screen of a television receiver is removed by supplying an intermediate frequency video signal including a desired signal and a ghost signal to a pair of parallel circuits, each including a synchronous or multi-plication detection circuit.  The detection axis or reference phase of the first detection circuit differs from the second detection axis or reference phase by an amount equal to the phase difference between the desired signal and the ghost signal.  Either the detected video signal in one of the parallel circuits or the intermediate frequency signal applied to one of the parallel circuits is delayed an amount equal to the delay time between the desired signal and ghost signal, and the signals from both circuits are combined in a suitable ratio to cancel the ghost signal.

Abstract: ABSTRACT           A biological cell analyzing system which is capable of automatically categorizing unstained biological cells as normal or non-normal.  The cells are made to flow through a transparent tube in single file and are scanned with a mixture of ultra-violet and visible light.  The cytoplasm and nucleus of each cell absorb ultra-violet radiation to different degrees, and the emergent light signal, as modulated by the scanned cells, is detected, amplified, and extended to a data processor which logically analyzes the signal from each cell on a real-time basis.  The visible light signal is subtracted from the ultra-violet light signal to improve the signal/noise ratio of the latter, and to automatically cancel out non-biological debris.          A number of acceptance tests are electronically performed on each cell, and if any of the tests is failed the cell is cate-gorized as non-normal.  Ambiguous conditions, resulting for example from the clumping of cells, are identified and sepa-rately counted.  The system can process up to several thousand cells from a single sample during a one-minute run.

Abstract: HIGH VERTICAL CONFORMANCE STEAM INJECTION PETROLEUM RECOVERY METHOD             (D#73,335-F) ABSTRACT OF THE DISCLOSURE           Viscous oil recovery methods employing well-to-well throughput steam injection are frequently less success-ful than anticipated because the process experiences poor vertical conformance, meaning that only a portion of the full vertical thickness of the oil saturated reservoir is contacted by the injected steam.  Because the specific gravity of the vapor phase portion of saturated steam is substantially less than the specific gravity of formation petroleum fluids, the vapor phase steam channels across the upper portion of the formation and only contacts and dis-places petroleum present in said upper portion of the formation, bypassing substantial amounts of petroleum in the lower portion of the formation.  By separating saturated steam into two components, one predominantly liquid phase and one predominantly gaseous phase, and injecting the hot liquid into the upper portion of the formation and the vapor into the lower portion of the formation, substantially greater amounts of formation petroleum are contacted and recovered by steam.  Steam may be separated into liquid and vapor phase components on the surface and injected by a separate flow path into separately completed intervals, or the separation may be accomplished in a downhole separator.     The process may be applied using steam alone, or other gaseous and/or liquid phase additives to steam may be injected in the same manner.            I

Abstract: ABSTRACT            A method for producing isotopically enriched material by photoexcitation of gaseous formaldehyde molecules in which at least one element is present as two or more isotopes, and in which the molecules which contain one of the isotopes have a greater tendency to absorb a given spectrum range of light than do the molecules of another of the isotopes.  Gaseous formaldehyde molecules are submitted to light in the given spectrum range in the presence of a stable paramagnetic gas.  The molecules are thus raised to an excited electronic state and those containing the first isotope are dissociated permitting the first isotope to enter into a different stable chemical state.  The matter constituting the first isotope can then be physically separated from the remainder.  The paramagnetic gas enhances the yield of such matter containing the first isotope.  Suitable paramagnetic gases are NO and O2. The technique is suitable for example in separating out 12C from other carbon isotopes.

Abstract: DISCONNECT SWITCH AND DRIVE MECHANISM THEREFOR              ABSTRACT OF THE DISCLOSURE         A disconnect switch and drive mechanism therefor particularly adapted for use in gas insulated substations.          The disconnect switch comprises a sealed tank having op-posing ends through which electrical conductors enter the tank, and within the tank is disposed an electrically in-sulating gas.  Also disposed within the tank are a pair of longitudinally spaced apart electrodes, and the electrical conductors are coupled to, and terminate at, the electrodes.          A reciprocating switch blade is disposed within one of the conductors and is capable of being in two positions; one position in contact with both electrodes to permit the flow of electric current therebetween; and a second position spaced apart from one electrode to prohibit the flow of electric current.  A drive mechanism is utilized for posi-tioning the switch blade.  The drive mechanism comprises a pair of parallel support members having a plurality of gear teeth at one arcuate end section thereof, first and second crank members pivotally coupled to the support members and having aligned openings therein, and a connecting rod ex-tending through the aligned openings and rotatable with respect thereto.  A crank gear is rotatably coupled to the first crank element and cooperates with the gear teeth of the support member, and a rod gear is fixedly secured to the connecting rod and cooperates with the crank gear, so that upon pivotal movement of the crank elements, the support member gear teeth cause the crank gear to rotate which causes a rotation of the rod gear and the connecting rod attached thereto.  A drive arm fixedly secured to the con-necting rod rotates with the connecting rod.  The connecting rod experiences both an arcuate and a rotational movement upon pivotal movement of the crank elements, and results in a straight line movement of the distal end of the drive arm.

Abstract: CAST ANNULAR LAMINATES AND METHOD AND APPARATUS FOR MAKING SAME               Abstract of the Disclosure A laminated product such as a tire is cast from chemically extending liquids which form a laminated solid in a mold.  The mold cavity is closed in preparation for use except for casting fluid inlet ports and exhaust vents.  The mold cavity defines the shape of the product to be cast.  Two or more chemically extendable liquids are injected into the mold without mixing through the inlet ports.  Each liquid is injected through a different port.  After injection, the liquids are arranged in alternate circumferential segments within the annular space.  At least one of the inner and outer surfaces which define the mold cavity is then rotated about the common axis to impart a spiral configuration to each of the injected liquids.  The liquids are then allowed to chemically extend to solids and form a laminated product such as a tire.  The products, when they comprise alternate layers of high and low elastic modulus materials, have better resistance to flex cracking than non-layered materials of similar composition having similar average stiffness.

This is accom-plished by providing voice frequency gain, a higher voltage talking battery, and supervisory and signaling circuitry for increasing the level of supervisory and signaling currents at the central office end.  The range extender requires no adjustment for loops of different lengths.  A          .pi. configuration negative impedance amplifier includes an adjustable gain circuit responsive to the resistance of the connected loop to automatically adjust the gain of the amplifier to the length of the loop.  At the same time, an impedance matching circuit is transformer-coupled to the loop.  The frequency shaping of the negative resistance amplifier and the impedance matching network, when reflected through the transformer, provides acceptable impedance matching for a wide range of loop lengths and wire gauges.  For stability, the gain of the amplifier is forced to a low value when the central office termina-tion becomes an open circuit.
