Patent number: 6811810Abstract: The forming of shapes using cement and/or concrete is an old art. In this process a form is removed, leaving the shape of the pattern which is the result of the form designed. Fluid concrete and/or cement can then be poured into the cavity to form the object. To increase the life of the forms, and to make removal of the form easier, the form must be coated with a protective material. Despite many available form release compounds, mineral seal oil, and a mixture of mineral seal and oleic acid, have been the commercial choices. A biodegradable form release composition including vegetable oil with a petroleum oil and/or an alcohol and a method of utilizing such a release composition to reduce adhesion between concrete and formwork or a mold is disclosed. The form release composition is biodegradable with a low VOC content.Type: GrantFiled: February 7, 2002Date of Patent: November 2, 2004Assignee: The Hill and Griffith CompanyInventors: Victor Steven LaFay, Stephen Louis Neltner

Patent number: 6749787Abstract: A mold used to form a magnetic member includes a mold body having a mold opening, a mold support that supports the mold cavity, and a mold insert. The mold insert is disposed in the mold opening of the mold body to form a mold cavity. The mold insert is coated with a coating to protect the mold body from chemical attack and abrasive wear of the mold material. The coating comprises an electroless nickel layer formed on or over the mold insert, and a chromium nitride layer formed on or over the electroless nickel layer. The mold insert can be formed of beryllium-copper (Be—Cu).Type: GrantFiled: February 28, 2001Date of Patent: June 15, 2004Assignee: Xerox CorporationInventors: Paul F. Mastro, Christopher D. Blair, Jennifer R. Wagner, Jay Schneider

Patent number: 6676872Abstract: A device for stamping a detergent bar, i.e. a bar comprising soap, a synthetic detergent active or a mixture thereof, includes a die. The die has at least one bar stamping surface provided with at least one elastomeric coating which includes a conductive filler such as stainless steel powder. Good release of the detergent bars from the die is possible particularly when the dies are chilled. Use of the conductive filler facilitates chilling of the dies.Type: GrantFiled: December 30, 1997Date of Patent: January 13, 2004Assignee: Lever Brothers Company, division of Conopco, Inc.Inventors: Edward Ross Story, Daniel John Heinz, Pasquale Michael Buzzeo

Patent number: 6659161Abstract: The present invention provides diamond tools, and a method for the formation thereof, using CVD techniques. In one aspect, an ephemeral mold is provided which has a diamond interface surface configured to inversely correspond to the desired shape for the working surface of a diamond layer in a tool. After the mold is provided, various CVD techniques may be used to deposit diamond layers upon the diamond interface surface of the mold. Following diamond deposition upon the diamond interface surface, the mold may be removed by various means, such as chemical etching, etc. Thus, the working surface of the diamond receives a shape which inversely corresponds to the configuration of the mold's diamond interface surface. The diamond mass may then be incorporated into a tool, if such incorporation has not yet taken place.Type: GrantFiled: October 13, 2000Date of Patent: December 9, 2003Inventor: Chien-Min Sung

Publication number: 20030178547Abstract: A process for producing an article with a microstructure includes the steps of forming a primary relief structure on a surface of a substrate, applying a photo resist on the substrate, exposing part of the photo resist using a photo mask so as to form a microstructure pattern, developing the microstructure pattern in the exposed photo resist, thereby allowing access to a part of the primary relief structure from the photo resist, and thereby forming a patterned surface with a microstructure relief that is bounded by the exposed part of the primary relief structure and by remainder of the photo resist on the substrate, and forming a metal layer on the patterned surface to form the article having the microstructure with a profile corresponding to the microstructure relief on the patterned surface.Type: ApplicationFiled: March 31, 2003Publication date: September 25, 2003Applicant: Taiwan Nano Electro-Optical Technology Co., Ltd.Inventors: Ying-Fu Wang, Yi-Tang Wang

Patent number: 6508961Abstract: A method for molding an optical disk includes applying a thermally insulative mold insert onto a thermally conductive mold form by coating the mold insert on the mold form. The mold insert has a coefficient of thermal expansion compatible with the coefficient of thermal expansion of the mold form and includes an adhesion promoting material. The method further includes positioning the coated mold form in a thermally conductive mold apparatus with the mold insert positioned between the mold form and the mold apparatus; injecting a molten thermoplastic material into the mold apparatus; retaining the molten thermoplastic material in the mold apparatus for a time sufficient for the molten thermoplastic material to cool below its glass transition temperature to form the optical disk; and ejecting the optical disk from the mold apparatus.Type: GrantFiled: August 4, 2000Date of Patent: January 21, 2003Assignee: General Electric CompanyInventors: Thomas Paul Feist, Thomas Bert Gorczyca
