Abstract: TITLE          COMBINED WET SCRUBBER-CLARIFIER UNIT            ABSTRACT OF THE DISCLOSURE      A combined scrubber-clarifier unit is disclosed adapted to remove particulate solids from a gas stream, the unit having improved scrubbing capability.  The unit is designed to reduce the tendency of deposits of particu-late solids to build up on interior surfaces of the scrub-ber unit tending to plug the unit.  The wets scrubber is mounted atop a scaled sludge-clarification tank, the tank being large enough to provide a retention time of about 30 minutes for the slurry.  The scrubber unit is one where-in the particulate-laden gas stream is directed through a verturi and directly impinged against the water held in the sealed sludge-clarification tank.  The scrubber unit has a central, hollow chamber therein through which the gases exit from the scrubber unit after passage through the water in the tank.  Mounted in the upper portion of the central chamber is a de-mister unit comprised of numerous slanted vanes which impart a swirling motion to moisture-laden gas passing there-through to centrifugally separate the water and residual particulate solids from the gas on passage through the vanes.           The water and particulate solids separated by the de-mister are collected and returned to the clarifying tank by a sump and drain pipes.  Plugging of the drain pipes and build-up of particulate solids on the vanes of the de-mister unit are prevented by direct spraying of water adjacent the openings leading to the drains and against the vane surfaces at all times.  The level of the water in the sludge clarification tank is maintained substantially constant by control means to assure optimum scrubbing capability.

Abstract: "INLET ASSEMBLY FOR AN OIL SEPARATOR"                 ABSTRACT OF THE DISCLOSURE           The inlet assembly is mounted within a separator vessel and comprises a housing similar in shape to that of a snail shell. This housing has a generally spiral side wall closed in by top and bottom end walls.  A feed pipe delivers pressurized crude oil tangentially to the inner end of the spiral side wall so that it rotates outwardly, following the length of said wall, to an outlet communicating with the interior of the separator vessel.  Gas is separated by centrifugation in the smaller radius central portion of the housing and then the liquid flow velocity is reduced by expansion of the stream in the larger radius outer portion.  Improvements in gas separation and emulsion reduction have been observed from use of the assembly.

Abstract: ABRIDGEMENT         This application relates to a method for making a precursor fuel composition, a prefuel liquid composition and a fuel composition, as well as the compositions per se. The method for producing a prefuel composition includes the steps of forming a non-homogeneous mixture of carbon, water, and petroleum oil and heating said mixture for a period of time and separating the resulting liquid from the solids of the mixture and burning said liquid in the presence of air for a period of time, and then removing the source of air to extinguish the flame.  The prefuel composition is made by taking the thus obtained precursor fuel composition and adding a certain amount of water and petroleum oil thereto to form a homogeneous mixture.  The fuel composition of the present invention is produced by adding to an oxidation resistant tank, from ?0% to 60%, by volume, of an aqueous solution of potassium hydroxide, sodium hydroxide, sodium bicarbonate, or mixtures thereof, and also adding a lower alkyl alcohol to said tank and transferring said prefuel composition (as defined hereinabove) from a separate container to said tank so that said prefuel composition mixes with said lower alkyl alcohol and aqueous solution, and continuing to add such prefuel composition to said tank until the tank overflows, and recovering thus obtained liquid fuel solution which has overflowed from the top of the tank.

Abstract: SYSTEM AND METHOD FOR SHARING MEMORY     Abstract A system and method for sharing memory are described wherein a plurality of time-shared buses are utilized.  A memory subsystem is connected to an addressable port on one bus and a non-memory subsystem is connected to an addressable port on another bus.  Access to the memory is achieved by the non-memory subsystem by generating a message having a destination code indicating an address on its own bus.  An inter-bus communication adapter is connected between the buses and intercepts the request-ing message.  The message is transmitted by the adapter while the destination code is altered to indicate the address of the memory subsystem on the other bus.  The receiving memory subsystem responds by generating a response message and placing the source address into the destination address position of the message.  The message is transmitted on the bus to which the memory is connected and is intercepted by a second inter-bus communications adapter.  The second adapter transmits the response message to the first bus for application to the requesting subsystem.

Abstract: ABSTRACT OF THE DISCLOSURE     A cutter pin for mounting on a mower disc having a keyed radial socket with a curved backstop adjacent thereto, the pin being tapered from shank to tip portion in the vertical plane but with the tip portion having substantially the same maximum width as the shank in the horizontal plane to provide a flattened blade-like structure with generally parallel lateral edges.  The pin is formed integrally of durable plastic having substantially the characteristics of nylon so that it stands out from the periphery in radially self-supporting position with sufficient stiffness for the cutting of grass as the disc rotates.  The tip portion has a sufficiently high width-to-thickness ratio and is smoothly merged with the shank so that when the pin strikes a weighty or fixed obstruction with a force having a random vertical component it bends backwardly engaging the backstop with distributed curvature accompanied by resilient twisting of the tip portion about the pin axis so that the engaged cutting edge turns away from the obstruction and so that a relatively flat side of the tip portion is presented for idly wiping-by the obstruction.  In the preferred form of the invention the pin is tapered substantially uniformly in the vertical plane from head to tip, with the tip portion being of lenticular cross section.  Also in the preferred embodiment the shank is formed with longitudinal ribs of tapering height defining flutes of tapering depth between them.

Abstract: METALWORKING FLUID COMPOSITIONS AND METHODS OF STABILIZING SAME          Abstract of the Disclosure Stabilized metalworking fluid compositions are dis-closed comprising an oil and water dispersion and, as a stabilizer therefor, a metal complex of a metal ion and a polyfunctional organic ligand.  The metal complexes have an aqueous proton induced dissociation property represented by a sigmoidally-shaped curve on a cartesian coordinate plot of the negative log of the metal ion concentration versus the negative log of hydrogen ion concentration.  This dissociation property causes a controlled release of metal ion into the oil and water dispersion to impart metal working stability to the dispersion.          Metal working emulsions of oil and water are stabilized by the addition thereto of minor amounts of a metal complex, e.g., disodium monocopper(II) citrate, which at alkaline pH metalworking conditions above about 7 to about 9 releases metal cations to the emulsions imparting stabilizing characteristics which prevent emulsion degradation by a number of factors commonly encountered in metalworking operations.  The stabilized compositions of this invention have greatly improved service life and offer signifi-cant economies in metalworking operations.
