Abstract: This invention relates to corrosion inhibiting compositions for aqueous systems comprising (a) polyaspartic acid or salts therefore, and (b) a water soluble phosphonated oligomer. The compositions are effective corrosion inhibitors, but are also advantageous from an environmental standpoint because they are non-toxic, contain no heavy metals, and have little or no phosphorus. They also have significant calcium/hardness tolerance, are chlorine/bromine stable, and are effective corrosion inhibitors.

Abstract: A gas impermeable vessel carrying a molten metal bath within the vessel bottom includes a downwardly directed baffle from a top wall of the vessel, which penetrates the bath to separate the vessel into a burner feed chamber and an outlet chamber with gas spaces above the level of the molten metal bath. A burner having a combustion chamber receiving an oxidant under pressure and fuel gas and pitch, combusts the pitch and passes the products of combustion at high velocity through a nozzle which opens directly or indirectly to the gas space above in the burner feed chamber such that a stream of carbon soot impinges against the surface of the molten metal bath and penetrates the same, thereby dissolving the carbon soot and disassociating gases such as carbon monoxide in the molten metal. Water may be supplied to the stream to effect disassociation of the hydrogen content in the molten metal.
Abstract: The subject invention relates to a foundry binder system that cures in the presence of a volatile amine curing catalyst. The binder system comprises a Part I component comprising (1) a phenolic resin component, and (2) a free radical initiator, and a Part II component comprising (1) a polyisocyanate, and (2) a multifunctional acrylate. The foundry binders are used for making foundry mixes. The foundry mixes are used to make foundry shapes that are used to make metal castings.

Abstract: This invention relates to foundry binder compositions that contain a divalent sulfur compound, and/or foundry mixes where the aggregate contains a divalent sulfur compound. The foundry binders and foundry mixes are used to make foundry shapes, e.g. molds and cores. The presence of sulfur in the foundry shape facilitates the removal of foundry shapes (particularly internal cores) from the metal casting which is made by pouring molten metal into a casting assembly in which the foundry shapes are arranged. The invention also relates to a method of preparing foundry shapes, the shapes prepared, a method of making a metal casting, and metal castings by this process.
Abstract: This invention relates to a defoamer composition comprising (a) hydrophobic silica; (b) a linear polysiloxane having end-blocked polyoxypropylene groups; (c) a polysiloxane having a pendant polyoxypropylene group; (d) a nonionic surfactant; and preferably (e) an inert diluent. The defoamer compositions are used in paints and coatings.
Abstract: A process and apparatus for preparation of custom blended fuels is disclosed. A bar code on a fuel tank or vehicle, such as an automobile, is scanned by a bar code reader operatively associated with a fuel dispensing means to convey information about a fuel required or desired to a computer controlled customized blender associated with the fuel dispensing means. Multiple fuel components, such as gasoline and replenishable fuel components such as methanol and ethanol may be custom mixed at the point of purchase. Preferably an octane analyzer and other fuel property analyzers, such as RVP analyzers, are associated with individual component or blended gasoline streams.
Abstract: An aqueous, plasticizer-retardant pressure sensitive adhesive (PSA) is made from an aqueous latex emulsion having an average particle size diameter of not substantially above about 100 nm and made from a mixture of ethylenically-unsaturated monomers and oligomers that include one or more of N-(iso-butoxymethyl) acrylamide, N-(n-butoxymethyl) acrylamide, N-methylol acrylamide; and emulsified in the presence of an emulsifier consisting essentially of:
In structure I, R1 is an alkyl, alkenyl, or aralkyl group containing between 6 and 18 carbon atoms, R2 is H or R1, R3 is H or a propenyl group; A is an alkylene group of 2 to 4 carbon atoms, n is an integer ranging from 1 to 200, X is H or SO3M, where M is an alkali metal, an ammonium ion, or an alkanolamine cation. Preferably, the ethylenically-unsaturated monomers include 2-ethylhexyl acrylate.

Abstract: A window securing device (36) for use in a double-hung sash window assembly having upper and lower sash window frames (14,16) installed for relative overlapping vertical sliding movement, said upper sash frame (14) having a recess into the interior of a vertical facial member of the window. The device (36) includes a housing (38) having a front faceplate opening (51) into a cavity (50) therein and a means for retaining the housing (38) in the recess with the faceplate (42) covering the edges of the recess. A pawl (40) mounted in the cavity (50) of the housing (38) is spring biased into an extended position where the lowermost arresting edge protrudes through the opening (51). In effect, the extended pawl (40) blocks the pathway of a top portion of the lower sash (16) for preventing further upward movement thereof.

Abstract: Used Motor Oil is re-refined by direct injection of a superheated, non-hydrogenating recycle vapor. The process operates at low pressures, preferably from atmospheric—10 atmospheres absolute. Preferably a significant amount of the energy required to vapor used motor oil is supplied in the form of increased sensible heat of a recycle vapor stream. Direct injection of superheated vapor reduces or eliminates fouling which can occur when indirect heat exchange is used to supply the heat needed to vaporize used motor oil.

Abstract: A process for the direct contact heating and vaporization of UMO is disclosed. A superheated, but condensable, vapor heats and vaporizes distillable liquid hydrocarbons from a waste motor oil stream, producing an overhead vapor fraction of injected superheated vapor and vaporized boiling range components. This material is cooled and partially condensed to produce lube boiling range liquid hydrocarbons and a vapor phase, which is condensed to produce a recycle liquid phase. Recycle liquid is pumped and then heated to produce superheated vapor for recycle to contact the UMO.
