Patent number: 5536763Abstract: A method of preparing a stainable resin material includes compounding 100 parts by weight of a resin material with from about 10 to about 30 parts by weight of a filler material being a plurality of individual filler particulate; and, heat polishing the surface of the material at a temperature sufficient to remove a portion of the material surface such that at least a portion of the filler particulate proximate to the surface is at least partially exposed. The filler material is selected from the group consisting of stainable materials. Products made using such a material may include striations to simulate the appearance of wood.Type: GrantFiled: June 5, 1995Date of Patent: July 16, 1996Assignee: Rubbermaid Office Products Inc.Inventor: Kenneth C. Foran

Patent number: 5262103Abstract: Disclosed is a cold molding process for the production of a unitary article from a plurality of plastic particles. The process may be conducted without the addition of heat. A plurality of homogeneous or heterogeneous plastic particles are introduced into a mold, softened by exposure to a softening agent, and thereafter compressed to form the unitary article. Preferred softening agents comprise an organic component and an aqueous component. One preferred softening agent-plastic combination comprises aqueous methylethylketone and polystyrene.Type: GrantFiled: November 21, 1991Date of Patent: November 16, 1993Assignee: Versi-CorpInventor: James P.

Patent number: 5244942Abstract: The invention concerns a homogenous, in particular multicolored plastic sheet or panel, based on ethylene vinyl acetate copolymer (EVA) as binder with a filler content of 30 to 80 wt. % and a process for producing it. In other embodiments the binder contains, in addition to the 70 to 85 wt. % of EVA, polypropylenes to improve the processability (tendency to adhere), EPDM to improve the flexibility, and polyethylenes to reduce the tendency to soiling. In the process described, several additives, each consisting of a binder containing at least some ethylene vinyl acetate copolymer, up to 80 wt. % of fillers and up to 5 wt. % of pigments, are mixed, plasticized and granulated or comminuted to form granules or chips of assorted colours which are mixed and, possibly after other processing operations, pressed to form the plastic web or plates.Type: GrantFiled: August 31, 1992Date of Patent: September 14, 1993Assignee: Huels Troisdorf AGInventors: Alexander Hover, Manfred Simon, Herbert Schulte, Josef Becker, Richard Weiss, Hans-Joachim Kaseler

Patent number: 5230852Abstract: In a method of feeding a plastic material to a using apparatus such as a molding press or an extruder, a moldable or extrudable plastic material in elongated strand form is provided. The moldable or extrudable plastic material is arranged such as in a package comprising a plurality of convolutions. The package is supported adjacent to the using apparatus and successive increments of length of the elongated strand material are payed out and fed into the using apparatus.Type: GrantFiled: December 11, 1991Date of Patent: July 27, 1993Assignee: AT&T Bell LaboratoriesInventor: Jerald L. Golmanavich

Patent number: 5229439Abstract: According to the invention a moulding is produced by compression and extrusion at a temperature between 120.degree. and 160.degree. of a mixture of heat-setting resin and at the most 30% related to the total weight of mixture of a filler with a grain size between 50 micrometers and 4 mm. The filler is a mineral filler and/or natural fibres.Type: GrantFiled: May 8, 1992Date of Patent: July 20, 1993Assignee: L'OrealInventor: Jean-Louis H. Gueret

Patent number: 5213854Abstract: The invention discloses a method of making articles and items with one or more surfaces with a solid stone-like appearance by filling a space with two materials, one of which is a finely cut-up material and the other of which is a filler. The method includes steps which eliminate the apparent thickness of the transparent medium through which the finely cut-up material is seen, thus enhancing the stone-like appearance.Type: GrantFiled: March 26, 1990Date of Patent: May 25, 1993Inventors: Michael J. Williams, Anna P. Williams

Patent number: 5154868Abstract: A method of manufacturing a randomly patterned floor covering having contrastingly-colored zones from a preform of rubber in which the preform is cut in pieces, each of which are molded into a blank having projections extending from a top side of the blank in relief-like fashion, solidified by vulcanization and then machined by cutting only in the region of the projections. The rubber forming the contrastingly-colored zones is mixed with contrastingly-colored particles in an amount of at least ten percent by weight. These particles are substantially free of flat surfaces and are in, at least, an advanced state of vulcanization. The particles located in the projections extending from the top side of the blank are exposed during the cutting step.Type: GrantFiled: November 28, 1990Date of Patent: October 13, 1992Assignee: Firma Carl FreudenbergInventors: Klaus Heckel, Herbert Arnold, Dieter Rischer
