  • Patent number: 4072791
    Abstract: A synthetic plastic sheet material having a multicolor striated pattern therein is disclosed. The synthetic plastic sheet material has a multiplicity of bands of differentially colored resin disposed within a matrix resin and the bands have striations extending longitudinally of the sheet material. Some of the bands extend angularly to others of the bands so as to provide a grid pattern. The bands of one angular orientation are disposed at a depth within the matrix material which is different from that of the bands of the other angular orientation. A multiplicity of bands of each orientation are provided across the width of the sheet material and the bands have relatively narrow striations extending longitudinally of the sheet material.

  • Patent number: 4057607
    Abstract: There is disclosed a process for preparing shear degradable particle-containing resin powders. This process comprises (a) preparing a first composition comprising shear degradable particles and molten resin in the absence of high shearing forces on the particles, (b) intimately blending the first composition with a second composition comprising molten resin and curing agent to form a shear degradable particle-containing molten resin mixture in the absence of high shearing forces on the shear degradable particles, (c) solidifying this shear degradable particle-containing molten resin mixture, and (d) grinding the solidified mixture to desired particle size. The particles may then be classified according to particle size.The final powder particles contain shear degradable particles or flakes in substantially undegraded form. The powder particles are especially useful in powder coating applications such as in automobile and appliance topcoats.

  • Patent number: 4048101
    Abstract: A foamed body having an annular ring pattern in cross-section is prepared by blending a powdery or particulate styrene resin A and a powdery or particulate styrene resin B and molding the blend by extrusion or injection molding. The resin A particles have foaming components incorporated on the surfaces thereof, prior to blending same with resin B. The resin B has a lower fluidity than that of resin A by a difference of melt index of 1 to 20, it has a particle size larger than that of the resin A powder or particles, it is free of foaming component, it has a color different from that of powdery or particulate resin A, and it is compatible with resin A.

  • Patent number: 4045529
    Abstract: Process for making producer-colored fibers, yarns, films and related products by extruding from a source, such as from an extruder, a flow of polymer to a spinneret placing in the path of flow between the polymer flow and the spinneret a dye solid or pigment solid having a predetermined shaped surface area, and flowing the polymer into contact against the exposed surface of the dye solid or pigment solid and by such contact dissolving at a predetermined rate a predetermined portion of the dye solid or pigment solid into the polymer flow and coloring the polymer flow for subsequent extrusion from the spinneret as colored filaments.

  • Patent number: 4017573
    Abstract: A process for making multicolored soap bars wherein a coloring agent is dispersed in a liquid oil vehicle and introduced into a base soap material before the base soap material is extruded in the form of a continuous log which is subsequently cut and pressed to form a multicolored soap bar.

  • Patent number: 4017574
    Abstract: A process for making multicolored soap bars wherein a coloring agent is dispersed in a meltable solid vehicle and introduced into a base soap material as a liquid colored material before the base soap material is extruded in the form of a continuous log which is subsequently cut and pressed to form a multicolored soap bar. The meltable solid material solidifies upon contact with the base soap material to form variegated, striated or marbleized colored regions in the final bar.

  • Patent number: 4011292
    Abstract: A method is disclosed for producing synthetic plastic sheet material having a multicolor striated pattern therein. The composite stream containing at least one band of differentially colored material in a matrix resin is passed through a perforated member having apertures therein separated by narrow solid segments which results in some interference with the lineal flow of the composite stream and effects striations of the differentially colored material within the matrix. A screen member supported in a perforated insert is specifically disclosed, and generally the bands of color extend diagonally across the sheet material.

  • Patent number: 3940220
    Abstract: Variegated detergent bars are made by mixing together pieces of soaps of contrasting colors in a vacuum zone and plodding the mixture in such manner as to fuse the different soaps together but maintain colors separate, thereby producing a desired pattern therein, preferably resembling marble. The pattern is controllable by variations of the proportions of material charged, plasticities thereof, speeds of the worms, design of the compression-extrusion head and preferably, by extruding the soaps through small openings in a plate after the final plodder worm, cutting the extrudates and imparting transverse or radial motions to them before final extrusion.Also described are plodding and extruding apparatuses utilized to practice the variegating process.
