The punch includes a tapered upper portion and a cylindrical lower portion for forming the hole in molded parts of varying thicknesses. The punch includes a tapered upper section defining an upper opening of a first radius in a top surface of the molded part and a cylindrical lower section defining an opening of a second radius in a bottom surface of the molded part. The cylindrical lower portion is sufficiently long that the bottom opening in the hole in each part formed will have the same second radius.Type: GrantFiled: July 31, 2000Date of Patent: January 18, 2005Assignee: GFP Strandwood Corp.Inventor: Bruce A. Haataja

Patent number: 6838024Abstract: The invention relates to a simplified production process with which it is possible to obtain carbon blocks, in particular anodes intended for aluminium production using the Hall-Héroult electrolysis process, which have high thermal shock resistance. This process comprises a grain size distribution adjustment operation of a carbon aggregate which includes: a) separating an initial ungraded carbon aggregate AC into a first fraction F1 made up of grains whose sizes are smaller than X, and into a second fraction F2 made up of grains whose sizes are X or greater, X lying between 0.2 and 2 mm; b) crushing B1 the first fraction F1 and part P1 of the second fraction F2 such as to obtain a powder F comprising a controlled proportion of ultra-fine grains; c) mixing the remaining part P2 of fraction F2 and said powder F in proportions with which it is possible to obtain crude carbon blocks whose so-called “Gr/S” ratio between the proportion PGr of grains larger than 0.Type: GrantFiled: November 21, 2000Date of Patent: January 4, 2005Assignees: Aluminium Pechiney, FCB AluminiumInventors: Christian Dreyer, Bernard Samanos

Patent number: 6833097Abstract: Disclosed is a novel biodegradable block for models, which has excellent workability and machinability and has mechanical properties suitable for models, while surely ensuring its biodegradability. The block is made of a biodegradable plastic material comprising a biodegradable polymer as the base polymer. The biodegradable polymer is a mixture comprising an esterified starch having a degree of substitution (DS) of about 0.4 or more and an esterified cellulose having a DS of about 0.4 or more, in ratio by weight, the former/the latter, of being from 10/0 to 1/9. The plastic material may further contain any of ester plasticizer and organic or inorganic fillers to make the block have desired physical properties.Type: GrantFiled: October 29, 2001Date of Patent: December 21, 2004Assignee: Japan Corn Starch Co. Ltd.Inventor: Nubuo Miyachi

Publication number: 20040247870Abstract: The present invention relates to a method for preparing an injectable composition of microparticles for the sustained release of a biologically active agent. The microparticles include a biocompatible polymer and a biologically active agent. The invention provides an improved process for the preparation of microparticles, wherein the physical characteristics of the microparticles, for example, the morphology, density and size, are independent of the process used to prepare the initially formed polymer/drug matrix. The method includes the steps of (a) providing a polymer/biologically active agent matrix; (b) compressing the polymer/biologically active agent matrix, thereby forming a compressed matrix; and (c) fragmenting the compressed matrix, thereby forming an injectable microparticle composition. The polymer/drug matrix can be provided by any suitable method.Type: ApplicationFiled: January 21, 2004Publication date: December 9, 2004Inventors: Josiah Brown, Warren E. Jaworowicz, Gregory C.

Patent number: 6824715Abstract: A method for forming a laminated sheet material from a slurry having a liquid component. The method comprising the steps of: applying the slurry to a substrate in successive layers to form a wet sheet of predetermined thickness; applying at least one of the layers by spattering; removing the wet sheet from the substrate; and drying or curing the wet sheet so as to remove at least a substantial proportion of the liquid component and thereby forming the sheet material.Type: GrantFiled: March 4, 2002Date of Patent: November 30, 2004Assignee: James Hardie Research PTY LimitedInventors: John Sydney Cottier, Greg Brunton, Robert Lyons
