Patent number: 5520896Abstract: The effluent stream from the treatment of glass with vapor-phase coating materials contains tin residues. By washing that effluent stream, in an apparatus having a scrubber bed and flow-control and -recycling means, with an acidic solution having a limited concentration of the tin residue, recovery efficiency of the post-coating treatment is improved, and process emissions are reduced.Type: GrantFiled: July 9, 1994Date of Patent: May 28, 1996Assignee: Elf Atochem North America, Inc.Inventors: Aart P. de Graaf, Georg H.

Patent number: 5002635Abstract: A method for producing a novel pulp, primarily wood pulp, from chips using pre-treatment with stabilizers and alkaline peroxide prior to mechanical fiberization (refining) to increase the brightness of the resulting fibers and the papermaking strength achievable with the fibers. The novel aspect of the pretreatment prior to refining is that it reuslts in the "in situ" formation within the chips of a stabilizing flock or sol.Type: GrantFiled: June 19, 1989Date of Patent: March 26, 1991Assignee: Scott Paper CompanyInventors: Victor M. Gentile, Jr., Harry D. Wilder

Patent number: 4389965Abstract: Heat activated, fabric conditioning products are made by impregnating a thick, absorbent substrate with fabric-conditioner chemicals. Such products are designed for use at elevated temperatures encountered in laundry dryers. This invention provides an improved process for making such products and an apparatus for applying liquids to the substrate. Previously a doctor blade was used in combination with a roller to limit the volume of liquid being applied to the substrate during compression of the substrate in a nip. The present invention concerns a thin wire drawn under tension which can function as the doctor to obtain a smooth thin film of liquid on the lower roller of the nip used for applying the liquid to the substrate.Type: GrantFiled: February 27, 1978Date of Patent: June 28, 1983Assignee: Scott Paper CompanyInventor: Rolf E. Christensen

Patent number: 4340386Abstract: Bleed-fast, dyed cellulosics particularly absorbent papers have been obtained with a particular class of water-soluble, cationic dyes reacted with a water-soluble aldehyde, preferably formaldehyde, glyoxal or glutaraldehyde. An aqueous printing fluid containing the water-soluble cationic dye and the aldehyde, upon drying, produces a water-resistant dyestuff having improved bleed fastness upon cellulosic fibers.Type: GrantFiled: November 14, 1980Date of Patent: July 20, 1982Assignee: Scott Paper CompanyInventor: Alex Pociluyko

Patent number: 4259082Abstract: Sodium sulfate crystals, also known as salt cake, are obtained as a side stream in the manufacture of chlorine dioxide by the reduction of sodium chlorate with chloride ions in an aqueous, acidic medium containing sulfate ions. The sodium sulfate crystals are contained in a mother liquor saturated with sodium sulfate and contaminated with chloride ions. The process provided by the present invention purifies the salt cake crystals by separating the crystals from the mother liquor without evaporation of the mother liquor until a critical dryness level is achieved and then the remaining mother liquor is evaporated to result in purified salt cake crystals having substantially reduced chloride ion content.Type: GrantFiled: June 7, 1979Date of Patent: March 31, 1981Assignee: Scott Paper CompanyInventors: Gregory J. Gianforcaro, Robert E. Lighton, Jerald M. Dougherty

Patent number: 4250005Abstract: Polyurethane foams having modified properties, such as increased tensile strength, tear strength and improved compression-deflection characteristics are prepared by incorporating in a foam-forming composition, an effective amount of a cross-link promoter, selected from the group consisting of polyfunctional, polyunsaturated acrylates; polyfunctional, polyunsaturated methacrylates; triallyl cyanurate; methyl methacrylate; 1,5-cyclooctadiene and bis (.beta.-chloroethyl) vinyl phosphonate. After a foam is prepared from the composition, it is exposed to a radiation dosage sufficient to modify the properties of said foam.Type: GrantFiled: August 20, 1976Date of Patent: February 10, 1981Assignee: Scott Paper CompanyInventor: Roland J. Lamplugh

Patent number: 4221562Abstract: Bleed-fast, dyed cellulosics particularly absorbent papers have been obtained with a particular class of water-soluble, cationic dyes reacted with a water-soluble dialdehyde, preferably glyoxal or glutaraldehyde. An aqueous printing fluid containing the water-soluble cationic dye and the dialdehyde, upon drying, produces a water-resistant dyestuff having improved bleed fastness upon cellulosic fibers.Type: GrantFiled: May 4, 1978Date of Patent: September 9, 1980Assignee: Scott Paper CompanyInventor: Alex Pociluyko
-
Patent number: 4196043Abstract: A Kraft pulp bleaching process comprising from one to about three treatments with ozone and a final treatment with an alkaline peroxide solution, the treatments being separated by an alkaline extraction, wherein effluent from the bleach treatments is utilized in subsequent bleaching operations or in the chemical recovery system of a Kraft pulping process.Type: GrantFiled: October 21, 1974Date of Patent: April 1, 1980Assignee: Scott Paper CompanyInventor: Rudra P. Singh

-
Patent number: 4159223Abstract: Chemicals produced during pulping operations are recovered and separated by passing chemical-containing liquors from said operations through one or more units containing activated carbon. The chemicals are recovered from said units by introducing a solvent into said unit and separating the materials removed therefrom in a fractionating column.Type: GrantFiled: October 16, 1975Date of Patent: June 26, 1979Assignee: Scott Paper CompanyInventor: Kenneth W. Baierl

Patent number: 4121960Abstract: An embossed film-to-foam laminate is provided having minute perforations through the film selectively distributed essentially along the sidewalls and valleys of the embossed pattern. The integrity of the laminated film material is retained on the crowns of the embossed patterned surface, since the perforations in the film material are mainly distributed on the sidewalls and valleys of the embossed pattern. The laminated product has a water-resistant and abrasion-resistant upper surface imparted by the film material on the crowns while the small perforations in the sidewalls and valleys permit sound to pass through the film and be exposed to the acoustical matrix of the open cell foam component of the laminate while impeding the penetration of liquids (e.g. water) through the film into the foam under the action of gravity. The film and/or the foam material are heated to supply adhesive material by melting or softening which serves to bond the film material to the foam.Type: GrantFiled: November 19, 1976Date of Patent: October 24, 1978Assignee: Scott Paper CompanyInventor: Bruce E. Focht

Patent number: 4096311Abstract: Wipe-dry characteristics of non-woven, dry-formed webs are improved by a post-treatment process that adds water and a surfactant to the web followed by wet-working the web. The effectiveness of the surfactant for improving the wipe-dry capability is noticeably enhanced by working the web while it is still wet with the water and the surfactant. Preferred surfactant addition is from about 0.5% to about 3% by weight surfactant based upon the weight of the web.Type: GrantFiled: October 31, 1975Date of Patent: June 20, 1978Assignee: Scott Paper CompanyInventor: Eugene J. Pietreniak

Patent number: 4076581Abstract: Wet-lay papermaking processes employing urea-formaldehyde resin in a papermaking slurry for imparting wet strength to the paper, are improved by addition of a water soluble salt of carboxymethylcellulose to the papermaking slurry, preferably when the urea-formaldehyde resin is dispersed in the slurry. The carboxymethylcellulose salt substantially increases the wet strength cure rate of the paper without significantly affecting the ultimate wet strength properties imparted to the paper by the cured urea-formaldehyde resin.Type: GrantFiled: January 16, 1976Date of Patent: February 28, 1978Assignee: Scott Paper CompanyInventor: Robert P. Avis
