Publication number: 20040012112Abstract: A three-dimensional printer uses inkjet-type printheads to rapidly prototype, or print, a three-dimensional model. A powder feeder includes a conveyor system and a metering system to deliver powder to a build area in measured quantities. The powder feeder also includes a vacuum system for loading powder into a feed reservoir or chamber. The vacuum system can also be used to cleanup excess powder. Other powder control features include powder gutters and magnetic powder plows. During printing, a cleaning system operates to remove powder from the printheads. In the event of a printhead or jet failure, the failure can be detected and corrective measures taken automatically. After printing, the model can be depowdered and infiltrated in an enclosure.Type: ApplicationFiled: September 27, 2002Publication date: January 22, 2004Applicant: Z CorporationInventors: Thomas Davidson, Robert A. Phillips, Andres T. Hernandes, David B. Russell, Kevin Roche, Walter H. Zengerle, Andrew Berlin, Joshua P. Kinsley, Benjamin Daniel Sweet-Block, Darul Kisai

Patent number: 6530766Abstract: An auxiliary device is disclosed for use with an injection molding apparatus for manufacturing disc-like information carriers. The device includes a holding device for holding an insert plate in a desired position, and a transporter, with at least two heads, for transporting successive insert plates between a plate supply holder and the mold. Each head centers and properly positions each plate within the mold using a tapered centering pin which extends from the head and into the mold wall.Type: GrantFiled: January 30, 1998Date of Patent: March 11, 2003Assignee: Axxicon Moulds Eindhoven B.V.Inventor: Jan Leendert Johannes De Graaff

Patent number: 6375874Abstract: A printer forms three-dimensional objects from a powder by selectively applying a binder liquid to incremental layers of the powder. The binder binds layers of the powder into solid two-dimensional cross sections of the desired object provided from memory. The printer can use dithering and halftoning techniques to shade the object and can also print in color. A filtration system removes airborne powder and recirculates the clean air. The printer also includes additional features to manage excess and airborne powder.Type: GrantFiled: October 13, 1999Date of Patent: April 23, 2002Assignee: Z CorporationInventors: David B. Russell, Timothy Anderson, James F. Bredt, Michael J. Vogel, Walter J. Bornhorst

Patent number: 6250907Abstract: A method of treating parts (34) in a treatment chamber (33) by hot-isostatic pressing with an inert gas as pressure medium and in the presence of a purifying agent (25a) for the inert gas comprises the steps of reducing the pressure in the treatment chamber (33), increasing the pressure again by introducing the inert gas, increasing the temperature in the treatment chamber (33) by activating heating elements (9a), and, after a certain holding time, reducing the pressure and the temperature again. Especially if the purifying agent (25a) is of the same material as the parts (34) being treated, the purifying effect of the purifying agent becomes insufficient. The effect of the purifying agent (25a) is improved according to the invention by bringing the inert gas, at least when being introduced, to circulate such that it is heated, passes through the purifying agent and is thereafter cooled before contacting the parts. The invention also relates to a device for carrying out the method.Type: GrantFiled: July 29, 1998Date of Patent: June 26, 2001Assignee: Flow Holdings GmbH (SAGL), LLCInventor: Carl Bergman

Patent number: 6231326Abstract: Prophylactic devices are made in an inert atmosphere by cooling mandrels on which the devices are to be deposited, dipping the mandrels into a polymeric material in a solvent/carrier and a mold release agent, rotating the mandrels during and after the dipping, and evaporating the solvent after dipping. The apparatus includes an air lock between a section in which these functions are performed and a section located in an air atmosphere for removing the devices from the mandrels, followed by cleaning the mandrels for use in a subsequent production run for making devices.Type: GrantFiled: September 21, 1999Date of Patent: May 15, 2001Assignee: Carter-Wallace, Inc.Inventor: Frederick P.

Patent number: 6214282Abstract: A cross head mounted at an end portion of an extruder for extruding a parison between a pair of elements of a metallic mold and a filling nozzle lifting apparatus having a filling nozzle are provided in parallel, and opening and closing of the metallic mold by a mold clamping apparatus, back and forth movement of the mold clamping apparatus between a parison receiving position and a filling position by a metallic mold feeding apparatus, upward and downward movement of the filling nozzle and back and forth movement of a parison cutter of a parison cutting apparatus are electrically operated. Further, a metallic mold body of the metallic mold is formed from a ventilation material, through which air in the metallic mold is sucked by vacuum to expand the parison. Furthermore, a clean air box is constructed so that it can accommodate the filling nozzle, and clean air is jetted from a jetting hole provided in a lower wall of the clean air box so that a clean air atmosphere may be provided above the metallic mold.Type: GrantFiled: July 12, 1999Date of Patent: April 10, 2001Assignee: The Japan Steel Works, Ltd.Inventors: Takaaki Katou, Masayuki Kishi

Patent number: 6168412Abstract: The present invention relates to a casting apparatus for formation of a resin-made membrane, which comprises a temperature adjusting unit (a temperature sensor, a heating wire type heater and a temperature controller) whereby an inner wall surface temperature of a suction chamber can be set to a desired temperature. Thus, if a design is made to prevent the temperature of the inner wall surface of the suction chamber from dropping, no contamination of the inner wall of the suction chamber by a volatile matter occurs, so that it is possible to prevent the volatile matter from dropping onto a cooling roll to make a membrane dirty.Type: GrantFiled: December 17, 1998Date of Patent: January 2, 2001Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Hideo Kometani, Toshio Miki, Masahiro Bessho, Yoshitomo Sakakibara, Daisuke Ooi, Noritaka Hasegawa
