Abstract: OIL RECOVERY BY WATERFLOODING EMPLOYING HYDROPHILIC CARBON OXIDE FOR MOBILITY CONTROL            Abstract of the Disclosure A method for the recovery of oil from an oil-containing subterranean formation by waterflooding employing as an injection medium an aqueous dispersion of a hydrophilic carbon oxide.  According to a preferred form of the invention, particulate graphite oxide characterized by a surface layer in which the molar carbon to oxygen ratio is from about 2 to about 3 is utilized as a viscosifier to decrease the mobility ratio between the injected water and oil, thereby improving the efficiency of the waterflood.  The graphite oxide may be characterized by a surface substantially free of -COOH groups, thereby being insensitive to divalent metal ions present in the subterranean formation.  According to another form of the invention, the graphite oxide is reactive with the divalent metal ions within the subterranean formation to  form a plug-ging deposit and thereby to function as a sealant for highly permeable strata within the formation.

Abstract: METHOD AND APPARATUS FOR ULTRASONIC       MATERIAL LEVEL CONTROL     Abstract of the Disclosure A method and apparatus for material level control in which an ultrasonic transducer is mounted at the top of a material tank and is directed to transmit pulses downwardly toward and receive echo pulses reflected upwardly from the upper surface of a stored material.  The echo signals from eight suc-cessive long-range pulses are digitized and then integrated according to apparent surface distance so that the sum of the true echo signals returned from the material surface is substantially greater than the sum of random noise signals for each transmitted pulse.          An ultrasonic transducer is also disclosed in which a piezoelectric crystal is bonded to a flat diaphragm with the neutral bending axis of the crystal/diaphragm combination being within the bond-ing agent.  The diaphragm is then pressed into the open end of a hollow shell to tune transducer resonant frequency, and a mixture of RTV and sand is cured with-in the shell to tune the transducer Q.

Abstract: TITLE      COOLING SYSTEM FOR A VEHICLE CLUTCH              ABSTRACT OF THE DISCLOSURE A cooling system for  a vehicle clutch including a cooling fluid distribution means and a heat exchange means.  A bell housing encloses the clutch assembly and provides a sump for containing cooling fluid.  A clutch pressure plate has a plurality of pickup tubes formed on its periphery which are passed through the cooling fluid as the pressure plate rotates with the engine flywheel.  The cooling fluid id forced through  the pickup tubes into the interior of the clutch assembly where the cooling fluid draws heat from the clutch elements and then drains back into the sump.  The inlet openings of adjacent pickup tubes are offset with respect to one another to increase the flow of cooling fluid.  The rotation of the flywheel and the pressure plate generates a flow of the cooling fluid in the pool.  A sump pan is connected to the bell housing and includes a baffle for diverting the flow of cooling fluid into the sump pan which is formedwith a corrugated bottom and finned sides to function as a heat exchange means.

Abstract: ABSTRACT OF THE DISCLOSURE            The disclosure is directed to improvement in stretch reducing mills utilized in the manufacture of seamless and welded tubing.  The stretch reducing mill is well known in its general-ities, and the disclosure is directed to improvements in the con-struction of such mills in the interest of increasing the effi-ciency of operation and performance of the mill.  The disclosure is directed in part to the construction of a multi-stand stretch reducing mill with improved arrangements for removably securing the individual mill stands in position.  This includes a heavy, massive structural beam from which all of the individual mill stands are suspended and which additionally serves, when the mill is ready for operation, as a means for holding the mill stands in position.  In the latter capacity, the beam contributes both in terms of its great weight and in terms of distributing clamping forces to the individual mill stands from a limited number of clamps.  The mill also includes an improved arrangement for longi-tudinally clamping together a series of consecutive mill stands, using a combination of hydraulic clamping cylinders and a mechani-cal fail-safe system, enabling the advantages of hydraulic clamp-ing to be enjoyed while avoiding any serious consequences from untimely failure of hydraulic pressure.  An additional feature of advantage included in the disclosure is an improved mechanism for effecting simultaneous coupling and decoupling of the indivi-dual mill stands to their respective individual drive motors.

Abstract: METHOD OF GETTERING USING BACKSIDE POLYCRYSTALLINE SILICON          Abstract An integrated circuit structure and method for manu-facturing same which provides for gettering with a back-side layer of polycrystalline silicon. The gettering of unwanted impurities from the integrated circuits involves the deposition of a polycrystalline silicon film on a semi-conductor wafer prior to any or some high temperature pro-cessing steps.  The semiconductor body is then subjected to the normal semiconductor processing steps to form semi-conductor devices on the surface opposite to the surface having the polycrystalline silicon layer.  During these high temperature processing steps, unwanted impurities such as copper, iron, nickel, sodium and potassium ions move toward and into the polycrystalline silicon layer and thereby away from the semiconductor devices.  This produces improved yield in the integrated circuit process.
