Abstract: Abstract A method is provided for reducing the oxygen demand of waste water having a partial organic composition, especially a solution commonly known as mostos which is the waste effluent of a molasses fermentation and distillation process.  The waste water is fed into an anaerobic digester near the top thereof so as to flow downwardly through the interior of the digester.  The digester is at least partially filled with a high surface area media.  The digester contains a microorganism which preferentially produces methane when in contact with the organic material in the waste water and also reduces the oxygen demand of mater-ials therein.  Also preferentially, the microorganisms tend to grow on the media surface.  Nitrogen and phosphorous containing materials are added as necessary to promote growth of the microorganisms.  As the waste water flows downwardly through the digester, methane is released therefrom which bubbles to the surface whereupon the methane is collected for combusting to produce energy,  A pH con-trol component may be added to the digester so as to produce an optimum pH for the process.  Preferred temperatures of the digesting process are 95 degrees F. and the range of 125 degrees to 130 degrees F.  During the process a portion of the biomass of the microorganisms growing on the media surface is sloughed there-from and settles to the floor of the digester.  The sloughed biomass along with a portion of the waste water is recirculated from the bottom of the digester to the top thereof, preferably at a rate of five times the flow of the influent to the digester.  An effluent flow is removed from the digester in such a manner as to overflow the top thereof without allowing atmospheric air therein.  When necessary to aid in removing biomass from the filter media, the collected methane may be selectively recirculated into the bottom of the digester and bubbled up through the waste water therein.  A pressure of approximately one pound per square inch is preferably maintained on the digester to urge carbon dioxide pro-duced during the process to remain in solution with the effluent.

Abstract: ABSTRACT OF THE DISCLOSURE    A plate grid, and a fluidized bed reactor incorporating the plate grid, are disclosed.  The plate grid includes air distri-bution apertures for delivering pressurized air to the reactor, and conduits for removing refuse, such as tramp material and/or agglomerated material, from the fluidized bed.  The conduits include downwardly diverging walls extending from the lower face of the plate grid support surface.  The fluidized bed reactor incorporating the plate grid further includes a chamber located below the plate grid support surface in communication at its upper end with both the air distribution apertures and conduits and at its lower end with a discharge port.  The method of operating the fluidized bed reactor includes filling the reactor, and consequently the chamber and conduits, with granular material to form a space between the top surface of the granular material in the chamber and the lower face of the support surface.          Pressurized gas is then introduced into this space and is discharged upwardly through the air distribution apertures. As refuse falls through the conduits, refuse and/or granular material is discharged through the discharge port at a rate to maintain the bed of granular material at a desired level.

Abstract: PHN. 9970                 13 ABSTRACT:              A system for the quantization of signals compris-ing in a transmitter section (IR) quantizing means (KW), a difference producer (DF1) and filter means (G1, H1).  An in-put signal (X) and a quantized output signal (Y) which is derived from the quantizing means and acts as a feedback signal are applied to the difference producer.  The output signal of the difference producer is applied by a network (G1) to the quantizing means having for  its object to quan-tize the level of the filtered output signal of the differ-ence producer.  Filter means (G1) are connected into the path of the input signal for relatively influencing the spectrum of the quantizing noise.  When digital signals are used the indispensable D/A-converters form a source of noise owing to threshold inaccuracy.  Here, the quantizing means (KW) are arranged to provide a second quantized output sig-nal (V).  In the receiver section RC a first recevied signal (Y') is applied to a first network (H1') and a second received signal (V') is applied to a second network (1/G1'). The output signals of the two networks are combined to one output signal.  The number of quantizing levels of the feed-back signal (Y) may in principle amount to two, in which case the relevant D/A-converter is free from noise caused by threshold inaccuracy.

Abstract: ABSTRACT OF THE DISCLOSURE            Many petroleum formations contain water having excessive quantities of salt or divalent ions such as calcium or magnesium dissolved therein, and are additionally at a temperature from about 70 to about 300°F. Most surfactants otherwise usable for oil recovery operations are either ineffective in high salinity or hard water, or decompose or precipitate at the higher temperatures encountered in formations.  An aqueous saline solution containing a sulfonate, ethoxylated alcohol or alkylphenol surfactant, either as the sole surfactant species, or as a co-surfactant with a more conventional anionic surfactant such as petroleum sulfonate, alkyl sulfonate, or alkylaryl sulfonate, is effective for use in formations containing water having substantial amounts of salt and/or divalent ion salts such as calcium or magnesium dissolved therein, and which additionally may be hotter than 120°F.

Abstract: ROBOT TEACHING INTERPOSER CONFIGURATION AND METHOD           ABSTRACT          A drillhole centerline determining interposer having a central pocket enables a robot to probe the interposer to learn the location and orientation of the desired drillhole.  The interposer is a mushroom shaped device with a planar head and a stem dimensioned to fit snugly in the hole to be drilled.  The interposer, in addition to the planar head from which the perpendicular can be calculated through multiple probes, has a central pocket concentric to the interposer stem.            The method of using the drillhole centerline determining interposer is to place a number of such interposers manually in position in holes in a master part located in the work envelope of the robot.  The robot operator prepositions the probe at an initial position facing the pocket of the interposer for a drillhole locating sequence for the related drill hole.  In sequence, the robot moves the probe from the initial position sufficient to clear the edge of the pocket and by multiple probes determines the plane of the interposer surface platform.  The robot then adjusts the yaw and pitch of the probe to orient the probe orthogonal to the platform plane (a vector parallel to the desired drillhole center-line axis).  The robot, with orientation vector stored, now locates the XYZ coordinates of the drillhole by pocket probing actions determining the epicenter of the pocket.            With orientation vector (pitch and yaw) known, and with coordinates (XYZ) known, the drillhole is determined.
