Patent number: 4390569Abstract: Disclosed is a process for coating the outside surface of a length of tubing comprising the steps of coating the outside surface of the tubing with an initial layer of coating liquid, transporting the coated tubing along its longitudinal axis in a substantially vertically upward direction; passing the coated tubing through a constriction of predetermined width to reduce the thickness of the initial layer and form a thin layer of desired thickness on the outside of the tubing; leveling the thin layer without reducing the weight per unit area of the thin layer to form a layer of uniform thickness; and exposing the tubing to heat of a sufficient temperature to solidify the coating liquid and form an uninterrupted film of uniform thickness on the outside of the tubing.Type: GrantFiled: March 26, 1981Date of Patent: June 28, 1983Assignee: Hoechst AktiengesellschaftInventors: Wolfgang Heinrich, Klaus-Dieter Hammer, Max Bytzek

Patent number: 4368240Abstract: A highly glossy skin of silicone rubber is produced on a roller body. The resultant rollers are adapted for use in the calendering of sheets and films of synthetic resinous material to produce a mirror-like finish thereon.Type: GrantFiled: July 27, 1981Date of Patent: January 11, 1983Assignee: Nauta Roll CorporationInventors: Jan P. Nauta, Jacob J. Kos

Patent number: 4353949Abstract: A method for producing a decorative design on a substrate by applying to the substrate an embossable coating comprising a filler, a binder, a release agent, a moisture control agent, and a liquid; drying the applied coating to remove a major portion of the liquid therefrom, sufficient liquid being retained to make the coating pliable and readily impressible by an embossing means; and subjecting the pliable coating to pressure contact with the embossing means, which is at ambient or an elevated temperature, to impress a decorative design into the coating; and the embossed coated substrate produced by the method.Type: GrantFiled: April 8, 1981Date of Patent: October 12, 1982Assignee: The Celotex CorporationInventors: Stanley C. Kyminas, Bernard J. Einhaus, Stephen G. Hinds

Patent number: 4341839Abstract: The present invention resides broadly in a method for the preparation of paper having improved water and/or solvent resistance which comprises applying to a base paper a plastic particle containing formulation, and then wetting the formed coating with a solvent to which the plastic particles are sensitive. The present invention is particularly applicable to the preparation of electrostatic paper masters of improved water resistance for lithographic printing having a photoconductive layer and a barrier coat to which the photoconductive layer is applied. The barrier coat contains a binding amount of a binder resin and filler at least a portion of which is an amount of said plastic particles sensitive to the solvent system of the photoconductive layer, the amount of plastic particles and sensitivity being sufficient to materially increase water resistance.Type: GrantFiled: December 17, 1980Date of Patent: July 27, 1982Assignee: Allied Paper IncorporatedInventors: Michael J. Shaw, Robert J. Thiessen

Patent number: 4339472Abstract: A method and an apparatus for fabricating gravure printing cylinders of synthetic resin in which a solution of a photosetting polyamide resin used as a coating resin is applied over the surface of a cylindrical base spirally as successively overlaid layers and thereafter the applied resin in subjected to drying by a heater and to photosetting by irradiation with ultraviolet rays, electron rays or the like. The resin layer surface thus obtained is mechanically engraved by an electronic engraver for forming gravure cells. The irradiation of ultraviolet ray, electron ray, or the like may be effected during or after application of the polyamide resin over the cylindrical base.Type: GrantFiled: July 18, 1980Date of Patent: July 13, 1982Assignee: Dai Nippon Insatsu Kabushiki KaishaInventors: Eiichi Tachibana, Shinichi Hikosaka

Patent number: 4324832Abstract: What is disclosed is a method for making a synthetic veneer, which method comprises impregnating a fibrous web structure with an aqueous dispersion of a finely divided synthetic resin, said dispersion further containing a water-soluble aminoplast resin dissolved therein, and then drying the impregnated web structure by heating it, said synthetic resin being thermoplastically deformable and in a non-crosslinked condition at the beginning of the drying step, but comprising a plurality of groups capable of external crosslinking and which do crosslink during the drying step.Type: GrantFiled: January 18, 1980Date of Patent: April 13, 1982Assignee: Rohm GmbHInventors: Helmut Moroff, Hanns Boessler, Hans Hauser, Gerhard Ladisich
