Abstract: A METHOD OF IMPROVED OIL RECOVERY BY SIMULTANEOUS  INJECTION OF WATER WITH AN IN-SITU COMBUSTION PROCESS            ABSTRACT     In a method of recovering heavy oil from a subterranean, permeable, heavy oil-bearing reservoir, an oxygen-containing gas is injected into the lower portion of the reservoir to establish an in-situ combustion reaction therein and to form a combustion front near the injection well.  Injection of the oxygen-containing gas is continued to advance the combustion front that heats the oil and generates gas to displace the oil through the reservoir towards a producing well.  Water is injected into the upper portion of the reservoir during combustion to prevent gases from migrating into the upper portion of the reservoir, scavenge heat from the combustion-heated portion of the reservoir, and displace oil from the reservoir, particularly the lower region, towards the production well.  The areal sweep efficiency of the injected water may be improved by the addition of thickening agents and water-soluble polymers.

Abstract: METHOD FOR FORMING A PLANARIZED INTEGRATED CIRCUIT                           Abstract A method is given for forming a planarized integ-rated circuit structure just prior to the formation of metallurgy interconnection lines on the integrated cir-cuit.  The method begins with the integrated circuit intermediate product having devices formed therein but before interconnection metallurgy has been formed on the principal surface of the product.  A glass layer is deposited in a non-conformal way onto the principal surface of the integrated circuit.  The glass is chosen to have a thermal coefficient of expansion that approx-imates that silicon and has a softening temperature of less than about 1200°C.  The thermal coefficient of expansion approximates that of silicon to reduce stress problems in the integrated circuit structure.  The relatively low softening temperature is required for the next step of heating the structure to cause the flow of glass on the surface of the integrated circuit product to fill in the irregularities therein and to thereby planarize the integrated circuit surface. Openings are then formed through the glass down to the device elements of the integrated circuit.  The inter-connection metallurgy is formed over the surface of the glass and through the openings of the glass to inter-connect the device elements of the integrated circuit. The glass may be deposited by various methods which include the sedimentation methods of spraying, cen-trifuging and spin-on plus sputtering or evaporation methods.

Abstract: ABSTRACT     In a combined generating plant utilizing a fluidized bed combustor in which coal or other carbonaceous fuel is burned at substantially atmospheric pressure, an external heat transfer unit is provided through which a portion of the hot solids of the fluidized bed is circulated through tubular channels.  Clean air from an air compressor is passed through the heat exchanger unit around the outside of the tubular channels, so receiving heat through them from the hot solids circulating therethrough, and is expanded in a gas turbine.          The flow of hot solids through the tubular channels is con-trolled independently of the operation of the combustor so as to accomodate varying loads on the generating units.  Steam for a other uses is generated by a conventional boiler and superheater in the combustor.

Abstract: AUTOMATED DATA ACQUISITION AND ANALYSIS            Abstract A mechanized system distributing the access, test and communication functions to the point of testing, typically the centralized switching facility or wire center serving the customer loops to be tested.  Computer stores information about each customer loop in the geographical area served by a system.  Front-end computers interact with computer to retrieve pertinent data regarding loops to be tested.  Each switching facility in an area includes a loop testing system that implements the required functions.  The communication functions residing in front-end computers and loop testing systems are coupled via a data communication network in a manner that allows any front-end computer to communicate with any loop testing system.  Users of the system control access and test from consoles having the capability of establishing independent communication paths over the national dial network for interactive tests on loops accessed through standard test trunks.          Microprocessor-based circuitry is utilized for numerous system tasks such as signal generation, digital signal processing and controlling sensitive analog measurements.          Signal generation includes digital generating of analog waveforms.  Signal processing techniques incorporate various digital filters to analyze sample sequences derived from, for example, dial pulses and coin telephone signals.          Sensitive analog measurements of loop characteristics are effected with a magnetic current detector that operates over broad current and frequency ranges.  Frequency dependent measurements are coverted to DC using synchronous demodulation techniques to enhance resolution.

This process is repeated until each washing step has received a flow of washing liquid.  To utilize the concentration raising capacity of the washing process and apparatus, before discharging the pulp, part of the drained fluid pipe system is emptied and the drained fluid therefrom obtained is returned to an earlier washing step.
