Abstract: A stabilizer composition useful as an additive for polyether polyols, particularly those employed in the manufacture of polyurethane foams, is provided which comprises a diarylamine, a sterically hindered phenol and a pentaerythritol diphosphite.

Abstract: The invention relates to the use of an acridans of Structure (I) as a stabilizer, preferably combined with hindered amine, phenolic, and phosphite stabilizers for stabilizing polyether polyols for polyurethane flexible foams and as stabilizers for the polyglycols, heat transfer fluids, lubricating additives.

Abstract: The invention relates to the use of certain styrenated diphenylamine and hindered phenol compositions for the stabilization of polyether polyols.

Abstract: Handles formed to fit various shapes, sizes, and designs of baby bottles available on the market. The handles aid in holding the bottle in proper feeding positions. The handles' unique design allows attachment and detachment, thus making the handles reusable. The attachment is by way of lugs positioned on the edge of the handles and various bottles will utilize different combinations of the lugs.

Abstract: There is provided a puzzle of nine basic geometric pieces, alternatively assemblable into a rectangle, square or five-pointed star, the nine pieces being subdividable and in their largest form being three right triangles, four isosceles triangles, and two quadrilaterals.

Abstract: Hydrocarbon products from viscous tar sands are recovered by continuously injecting a hot solvent containing relatively large amounts of aromatics into the formation. Alternatively, steam and solvent are cyclically and continuously injected into the formation to recover the values. The last stimulation is by steam so that solvent is recovered. A third alternative is to continuously inject a mixture of steam and solvent vapors and liquid into the formation. In all cases, the solvent, except perhaps for startup, is produced at the site, as in a conventional topping unit, which alternatively is combined with a conventional visbreaking or reforming unit to increase the volume and/or aromaticity of the solvent produced.
