Abstract: ALCOHOL SEPARATION PROCESS                      ABSTRACT OF THE INVENTION          The process involves the separation of monohydric and polynydric products from a liquid homogeneous mixture obtained from the reaction of hydrogen and oxides of carbon in a solvent solution containing a Group VIII metal carbonyl complex catalyst by extracting said solvent solution with a liquid polyhydric alcohol having at least four carbon atoms and at least four hydroxyl moieties at a temperature of at least 50°C.  Further, the process is advantageous in that it can be effected under pressure in the presence of oxides of carbon.                S P E C I F I C A T I O N

Abstract: HOT MELT FOAM ADHESIVE SYSTEM            Abstract of the Disclosure A hot melt foam adhesive system including a gear pump wherein gas is mixed under pressure into the molten adhesive and is driven into solution with the adhesive.  The gas is supplied to the pump via a one-way check valve operative to prevent the back flow of molten adhesive to a gas flow control valve, regu-lator, and gauge.  The check valve is positioned above the level of the pump so that molten adhesive cannot flow by gravity into the check valve.  The check valve is so constructed that it is biased into a closed position by a spring on the gas side of the valve so that adhesive cannot collect around and foul the spring of the valve.

Abstract: TITLE OF THE INVENTION       METHOD AND APPARATUS FOR PREPARING EMULSIONS            ABSTRACT         Method and apparatus for continuously producing emulsions with particles of a disperse phase liquid in a continuous phase liquid, employing an emulsifying vessel which is interiorly provided with a gravitative flow surface and a feeder for supplying the continuous phase liquid to the flow surface for forming thereon a stream of the continuous phase liquid.  On the other hand, disposed within the emulsifying vessel is a rotary atomizing head which is connected to a disperse phase liquid source and a rotational drive means and maintained at a high voltage to stratify and form a spray of atomized particles of the disperse phase liquid flying toward the flow surface under the influence of centrifugal force and electrostatic action.          The disperse phase particles from the rotary atomizing head are entrained and dispersed in the stream of the continuous phase liquid on the flow surface of the emulsifying vessel to form an emulsion.  The resulting emulsion is collected in a receptacle.  In some case, the emulsifier is provided with a hot steam feed pipe for feeding hot steam to the rotary atomizing head to prevent solidification of atomized disperse phase particles on the atomizing head.

Abstract: ABSTRACT    The tamper has tamping tools intended for tamping the open track and the  switch gear.    Each tool is mounted on an oscillating and pivoting lever (6) and has a fixed pick (20) and a pick (21) displaceable by pivoting in a plane transverse to the track around a shaft (23) which is rigidly connected to the lever (6) and by means of a cylinder (26).    The tappets (22) of these picks are offset and partially cover one another in the close-together position and the picks are arched towards the outside so as to leave sufficient space between them for the flow of the ballast above the tappets.    The switch gear is  tamped in close-together position of the tappets over a reduced length (R) and the open track is tamped in spaced position over a greater length, the stroke of the cylinder (26) limiting and defining these two positions.

Abstract: Abstract of the Disclosure A machine for folding and gluing a continuous web in high speed operation.  A continuous web which has solidi-fied glue thereon in selected regions is folded.  Heat is applied to the folded web to melt the glue, particularly in specific areas of the folded web.  Pressure is applied to the specific areas to urge together the folded portions of the web and the melted glue therebetween.  Then the folded web travels between heat transfer members which rapidly cool the folded web and the glue between folded portions thereof.  Thus, the glue is solidified and the folded portions are firmly adhesively attached together.

Abstract: A VEHICLE-MOUNTED APPARATUS FOR SUPPORTING BALLAST WEIGHTS    AND FOR ELEVATING THE WEIGHTS                   Abstract of the Disclosure A tractor-mounted apparatus is disclosed for supporting ballast weights on the front or rear of the tractor and for elevating the weights relative to the ground.  The apparatus includes a pair of U-shaped channels fastened to frame members of the tractor in an upright position.  The channels are aligned with their open faces opposite to one another such that the ballast weights can be received therebetween.  A pair of hydraulic cylinders are each secured at one end to one of the U-shaped channels and each has an outwardly extending piston rod detachably coupled at its lower end to the ballast weights.  The piston rods are moved into and out of the hydraulic cylinders by a control mechanism thereby permitting the ballast weights to be raised and lowered in a substantially vertical fashion.  The apparatus also includes means for permanently locking the ballast weights to the U-shaped channels while the ends of the piston rods are connected to the lower links of an attached implement.  In such an arrangement, actuation of the piston rods permits the implement to be raised and lowered with respect to the tractor's frame.

Abstract: Abstract of the Disclosure A pivot hinge has two pivot members for engaging bores in two parts to be rotatably coupled to each other.          Each pivot member has a first portion sized for insertion into one of the bores.  Either a single continuous rib or a plurality of rib segments are formed on the outer surface of the first portion for gripping the inner surface of the bore.          Either one or both of the pivot members has a second portion which provides a thrust bearing between the two joined parts.          The two pivot members are coupled to each other by a bearing which allows each member to rotate independent of the other and a releasable lock mechanism which, when engaged, prohibits lateral separation of the two pivot members and, when disengaged, permits separation of the two members to allow separation of the parts.

Abstract: ABSTRACT OF THE DISCLOSURE       A method for predicting the optimum cycle time to schedule sootblowing using on line process measurements.  The optimum cycle times dynamically adjust to changing conditions resulting from boiler operation, fuel changes, or seasonal changes.  The optimum cycle time is calculated four times per second for each heat trap of a boiler.  The optimum conditions are based on economic criteria which account for heat trap fouling, rate of fouling of other heat traps within the boiler, and on line boiler incremental steam cost.

Abstract: ABSTRACT OF THE DISCLOSURE       A blind having an interior side an an exterior side and having a plurality of elongated slats.  The slats are made of a flexible and generally resilient polycarbonate plastic material having selected light-transmitting qualities.  Each slat has generally V-shaped transverse cross sectional configuration in which a first portion and a second portion of the slat correspond to the two sides of the V, intersecting at an angle of 90° to 160°.  Means are provided for suspending the slats in parallel relation, the suspension means being adapted to rotate the slats about their longitudinal axes between an inwardly facing position, in which the upper surfaces of the slats are presented at the interior side of the blind with the first portions of the slats substantially co-planar, and an outwardly facing portion, in which the upper surfaces are presented at the exterior side of the blind and the second portions of the slats are substantially co-planar.  The slats are held at a distance from each other such that when the slats are in one of the inwardly facing and outwardly facing positions, the portions of the slats not then co-planar extend sufficiently far toward the slat immediately adjacent thereto as to overlap the immediately adjacent slat, to prevent the passage of light in a direction generally normal to the co-planar portions of the slats without that light being interrupted by the slats.
