Patent number: 7153119Abstract: An extruding apparatus for food materials having a filling material and a wrapping material extrudes and envelops the filling material with the wrapping material. An internal cylinder supplies the filling material while a concentrically arranged external cylinder creates an annular space for extruding and enveloping the material supplied. The wrapping material is fluidized by a fluidizer accommodated in the annular space. A driving mechanism is sealed from the fluidizer and drives the fluidizer in the annular space. The driving mechanism is driven by a transmission mechanism. A storage space section near the seals prevents wrapping material from penetrating the driving mechanism.Type: GrantFiled: May 13, 2003Date of Patent: December 26, 2006Assignee: Rheon Automatic Machinery Co., Ltd.Inventors: Shigeru Hashimoto, Kiyoshi Hasegawa

Patent number: 7153118Abstract: A tablet press machine (100) comprises: a hopper (1) for feeding a powder or granular product (2) to a first disc (3a) that rotates about an axis (X) and is equipped with evenly distributed holes or dies (3); a second and third disc (4, 6) that are positioned above and below the first disc (3a), respectively, rotate about the axis (X) and support respective pluralities of upper and lower reciprocating punches (5,7). The punches (5, 7) are driven towards and away from each other when they are aligned with the dies (3) in such a way as to compress the product (2). Each of the punches (5, 7) comprises a cylindrical shank (8), one end of which is equipped with a working head (10) and sealed protection means (11) acting on the cylindrical shank (8) itself.Type: GrantFiled: August 6, 2004Date of Patent: December 26, 2006Assignee: I.M.A. Industria Macchine Automatiche S.p.A.Inventors: Roberto Trebbi, Hans Kramer

Patent number: 7114943Abstract: A post processing apparatus for automated removal of support material from a three-dimensional objected formed from a build material by selective deposition modeling is provided. The apparatus includes a heated main chamber into which is placed the three-dimensional object with the support material attached and first and second liquid heat transfer medium storage reservoirs. The storage reservoirs reversibly provide liquid heat transfer medium to the main chamber to immerse the three-dimensional object and the attached support material for desired periods of time to meltingly separate the support material from the object.Type: GrantFiled: May 11, 2005Date of Patent: October 3, 2006Assignee: 3D Systems, Inc.Inventors: Jon Jody Fong, Raymond M. Soliz

Patent number: 7074029Abstract: A by-product waste material removal system for solid deposition modeling. As excess build and support material is removed during the build as a by-product waste the removal system accumulates, measures, and releases the by-product waste material into a waste receptacle for disposal. The by-product waste material removal system requires no mechanical vacuum systems and allows operator intervention to remove and replace waste receptacles without interrupting an ongoing build.Type: GrantFiled: July 23, 2003Date of Patent: July 11, 2006Assignee: 3D Systems, Inc.Inventors: John S. Stockwell, Raymond J. Bishop, Raymond Mathew Soliz, Jon Jody Fong
