Abstract: ABSTRACT OF THE DISCLOSURE An override process control system for regulating a process with a single final control element, such as a valve, from two or more process variables that are interdependent and must not exceed acceptable minimum and maximum limits.  The system includes a like number of electronic controllers each acting to compare a respective process variable with a set point to produce an output signal reflecting the deviation of the process variable from the set point.  The primary controller responsive to the process variable directly influenced by the setting of the final control element has its output signal applied thereto to regulate this element, whereas the other controllers which are responsive to secondary process variables operate on a standby basis. Coupled by individual lines to the several controllers is an override selector station which monitors the operation of the controllers, and in the event an unsafe signal is received from one of the standby controllers, forces the primary controller to respond to the unsafe signal until such time as the signal is again safe.

Abstract: METHOD OF TREATING ORGANIC WASTE WATER            Abstract of the Disclosure:       Method of treating organic waste water in an aeration tank is disclosed herein.  Said method is characterized by the fact that (1) the dissolved oxygen content in the aeration tank is adjusted to be within the range of 1.5 - 4.5 ppm;          (2) the temperature of the waste water is controlled to be within the range of 15 - 40°C and the residence time of the waste water in the aeration tank is set at ten or more days if the ratio of the total carbon content to the nitrogen content of the organic materials contained in the waste water (TOC/N) is not less than 5, and the temperature of the waste water is controlled to be within the range of 20 - 40°C and the residence time of the waste water in the aeration tank is set at ten or more days if the TOC/N is less than 5 and not less than 2.5, and (3) the activated sludge content in the aeration tank is kept constant by controlling the amount of COD to be removed according to the equation:                  ? T = 33.5 x 1.058(T-20) wherein T is a temperature (°C) of the waste water to be treated, and ?T is COD(Cr) to be removed (Kg)/ATP content in the aeration tank (Kg)/day at T°C.

Abstract: ABSTRACT OF THE DISCLOSURE     A gun drill for forming a hole in a metal workpiece consist-ing of a generally cylindrical body having a shank portion and a tip portion.  The body has a longitudinally extending groove formed in its outer surface which extends the full length of the tip portion, and the terminal end of the tip portion has a single cutting edge which extends radially through the axis of the tip portion adjacent the terminal end of the groove.  The tip portion is formed interme-diate its ends with a wall section located to one side of the groove and in substantial alignment with the cutting edge in a direction longitudinally of the body.  A pair of fluid passages are formed in the body, one terminating at the wall section in an orifice directed toward the cutting edge, and the other terminating in an orifice located in the terminal end of the tip portion in a spaced relation with the cutting edge.  Fluid discharged through the orifices acts to flush metal chips removed from the workpiece by the cutting edge into the groove for reverse flow out of the hole being drilled.  An inclined surface is formed on the tip portion extending in a direction axially of the drill from the wall section rearwardly toward the shank portion to further facilitate fluid flow and chip flushing at the tip portion of the drill.

Abstract: ABSTRACT Information is stored, using a relatively low-power light beam, by redistributing the material in a deformable film.  In a disc configuration, positioning of the light beam is achieved by referencing to a previously re-corded track.  In a document storage and retrieval system the document is scanned with the resultant scanned signal modulating the writing light beam producing a recorded track.  This track is optically read with the resultant signal applied to a printer.  For optimum utilization of the area, the re-cording and readout take place at constant velocity.

Abstract: PRODUCTION OF PURIFIED SYNTHESIS GAS AND CARBON MONOXIDE       (D#76,169-F) ABSTRACT         A continuous process for simultaneously producing (1) a stream of purified synthesis gas having a controlled mole ratio H2/CO, and (2) a separate stream of CO-rich gas.  Methanol may be synthesized from the purified synthesis gas and reacted with CO to produce acetic acid. In the process, raw synthesis gas from a noncatalytic partial-oxidation gas generator is cleaned (if necessary), cooled, and dehumidified.  At least a portion of the resulting gas stream is then partially purified by removing H2S and COS if present, and at least a portion of the CO2 in a first gas purification zone.  The remainder of the clean dehumidified gas stream if any, by-passes the first gas purification zone.  Partially purified gas from the first gas purification zone is introduced into a second gas-purification or separation zone and at least a portion of the remainder if any, by-passes the second gas purification zone.  A product stream of CO-rich gas and a separate stream of H2-rich gas is removed from the second gas purification zone.  The product stream of purified synthesis gas may be then produced by mixing together at least a portion of said H2-rich gas stream with at least a portion of at least one of the following by-pass gas streams: (a) gas processed in the first gas purification zone that by-passes the second gas purification zone; (b) clean dehumidified gas that by-passes the first gas purification zone.

Abstract: ABSTRACT OF THE DISCLOSURE     A portable, or travel-type, oral hygiene appliance is provided with simplified and effective means for producing a pulsating, or intermittent, liquid jet; and optionally in-cluding a light stick for obtaining locally-concentrated illumination of areas within the mouth.  The appliance is of lightweight and compact construction, in the form of an appli-ance casing having reduced vertical thickness and with a fold-able water container carried on a portion of the upper surface of the casing.  The pump for propelling a pulsating liquid jet uses a rotating member carrying spaced roller elements that move against a resilient, flexible, hose with a water column therein, to compress the hose between each roller and an abutment, thereby applying impeller force to spaced seg-ments of the liquid column, so as to obtain an intermittent high pressure, liquid jet, discharge.  Aspirated air is intro-duced into the water column upstream of the pump to aid in the interruption, or chopping, of the liquid column by the pump into pressurized pulses of liquid.  A manually actuatable controller downstream of the pump operates to control volume discharge from the pump.  A lighting stick, may be provided as an optional attachment, and is energized by the electrical supply for the appliance.

The sponge wringer is rotated essentially 360° so that it is aligned with the mop handle when the sponge is fully wrung out.  When the mop is in the mopping position, the handle can be lowered or raised with respect to the surface being mopped, while the sponge remains flush on that surface, by insertion of tabs on the sponge wringer in selected openings provided in the base plate for different handle orientations.
