    Abstract: WHEREIN R AND R'' ARE INDEPENDENTLY AT EACH OCCURRENCE HYDROGEN, METHYL OR ETHYL AND R, S, AND T ARE INTEGERS FROM 31 TO ABOUT 200. HOWEVER, WITH INCORPORATION OF THIS ANTISTATIC ADDITIVE IN THE POLYAMIDE, SERIOUS PROBLEMS HAVE BEEN ENCOUNTERED IN MELT-SPINNING DUE TO THE FREQUENT OCCURRENCE OF "NUBS OR ENLARGED PLACES IN THE EXTRUDED POLAMIDE FILAMENT. IT HAS NOW BEEN FOUND THAT THE OCCURRENCE OF SAID NUBS IN THE ANTISTATIC POLYAMIDEFIBER CAN BE GREATLY REDUCED BY DISPERSING IN THE POLYMER AT LEAST 0.5% BY WEIGHT, BASED ON THE WEIGHT OF THE ANTISTATIC AGENT, OF A PHENOL COMPOUND REPRESENTED BY THE FORMULA: 2-R2,4-R1,6-R3-PHENOL WHERE R1 IS HYDROGEN OR AN ALKYL RADICAL CONTAINING 1 TO 5 CARBON ATOMS, R2 IS AN ALKYL RADICAL CONTAINING 12 TO 18 CARBON ATOMS, AND R3 IS AN ALKYL RADICAL CONTAINING 12 TO 18 CARBON ATOMS, AND AT LEAST 0.5% BY WEIGHT, BASED ON THE WEIGHT OF THE ANTISTATIC ADDITIVE, OF A SULFUR COMPOUND OF THE FORMULA. R4-OOC-CH2-CH2-S-CH2-CH2-COO-R5 WHERE R4 IS AN ALKYL CONTAINING 8 TO 18 CARBON ATOMS AND R5 IS AN ALKYL RADICAL CONTAINING 8 TO 18 CARBON ATOMS.

    Abstract: The rate of fading of dyed textiles due to ozone action is substantially reduced through the incorporation therein of: A. A COMPOUND CHOSEN FROM THE CLASS OF AMINES WITH ETHYLENEOXY SUBSTITUENTS HAVING THE STRUCTURAL FORMULAS:

    WHEREIN R is an alkyl or aralkyl radical with four to 25 carbon atoms, and x, y and z are integers such that x + y is equal to or less than 10 in A compounds and x + y + z is equal to or less than 10 in B compounds; and B. A PHENOLIC COMPOUND CHOSEN FROM THE GROUP CONSISTING OF 4,4''BUTYLIDENE BIS(6-TERT-BUTYL-M-CRESOL), P-NONYLPHENOL, 1,3,5 TRIMETHYL-2,4,6-TRIS (3,5 DI-TERT-BUTYL-4-HYDROXY BENZYL) BENZENE, AND 6-TERT-BUTYL-M-CRESOL.

    Abstract: A method of making an embossed panel including dual extruding a molding strip in the form of a composite duplex structure having a plastic support member with a first heat sealable plastic layer fused thereto and disposing a second heat sealable plastic layer onto a panel backing member. The first and second heat sealable layers are disposed adjacent one another and are heat sealed and fused together to conjoin the molding strip to the second heat sealable layer such that the support member projects from the panel.

    Abstract: Method for removing liquid from a non-absorbent article comprising immersing the article into a vigorously agitated solvent bath, transferring displaced liquid and solvent directly to a separation zone, withdrawing liquid which collects as one phase in the separation zone, removing solvent which collects as another phase in the separation zone, recycling this solvent to the solvent bath, and removing the article from the solvent bath. An alternative to the solvent bath is a spray treatment. Apparatus comprises various sumps and piping to accomplish the above, including at least one sump equipped with means for the vigorous agitation of liquid contained therein, such as ultrasonic vibration means if a solvent bath embodiment is employed, or at least one sump equipped with a spraying means if the spray treatment embodiment is employed. The above-described systems are particularly adapted for the removal of water from non-absorbent articles, and particularly articles with relatively inaccessible surfaces.
