The mold includes a die defining a cylindrical cavity having an inner diameter substantially equal to an outer diameter of the flanges. A pair of die inserts are movable in an orthogonal direction relative to the cylindrical cavity and define a diameter of the coil winding core portion of the drum shaped magnetic core. The diameter of the coil winding core portion is smaller than the outer diameter of the flanges. An upper punch and a lower punch are inserted into the cylindrical cavity from a corresponding end opening of the mold such that each forms a flange. A central punch is disposed coaxially within one of the punches to form the coil winding core portion.Type: GrantFiled: May 23, 1997Date of Patent: September 5, 2000Assignee: Minebea Co., Ltd.Inventors: Hiroshi Tsuboi, Toshinori Okamoto, Kunio Kojima

Patent number: 6103179Abstract: The invention relates to a method and an arrangement for manufacturing a fiber product. The method and the process are characterized in that a first male mold (6) is immersed in stock in a molding tank (2a). By means of a vacuum, fibers are induced to form a fiber layer of predetermined thickness on the male mold (6). The male mold (6) is thereafter removed from the molding tank (2a) and a female mold (8) is brought under force against the male mold (6) in order to express the stock water, following which the fiber product (P) is transferred to the female mold (8). A second male mold (10) is brought under force against the female mold (8) so that the fiber is subjected to pressing in order to increase the dry solids content of the fiber product and give this a predetermined external structure, following which the fiber product (P) is released and subjected to final drying under the effect of microwave or IR radiation.Type: GrantFiled: June 12, 1998Date of Patent: August 15, 2000Assignee: Celtec Development ABInventor: Johan Peter Larsson

Patent number: 6004120Abstract: An apparatus for manufacturing a pressed powder body has a die assembly comprising an upper die and a lower die, for pressing an unpressed powder body of a material powder filled on a pressing surface of the lower die, into a pressed powder body between the upper die and the lower die, at least one of the upper die and the lower die being vertically movable to press the unpressed body, and a powder increasing mechanism for increasing an amount of the material powder locally in the unpressed powder body. The powder increasing mechanism comprises at least one of the upper die and the lower die, the at least one of the upper die and the lower die comprising a first die member for pressing a first portion of the unpressed powder body at a first time and a second die member for pressing a second portion of the unpressed powder body at a second time which is different from the first time.Type: GrantFiled: April 29, 1996Date of Patent: December 21, 1999Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Sadao Matsubara, Noboru Sugiura

Patent number: 5976599Abstract: An apparatus for the preparation of bread dough rolls is provided. The apparatus includes a first press for spreading the bread dough blank across the top surface of the mold and forcing a portion of the bread dough blank at least partially into the at least two depressions; and a second press for further spreading the bread dough blank across the top surface of the mold and forcing a portion of the bread dough blank completely into the at least two depressions. This provides a bread dough roll which can have a cross-section of intentionally varying thickness.Type: GrantFiled: March 17, 1998Date of Patent: November 2, 1999Assignee: Campagna Turano Bakeries, Inc.Inventor: Frank R. Biernacki

Patent number: 5939104Abstract: A mold box assembly includes a rectangular mold box frame having a substantially vertical divider plate mounted on the frame and extended part-way into it from an the upper side of the frame. A pair of rectangular restrictor plates are disposed vertically in the mold box from side to side and extend to the same depth as the divider plate. Wet product mix is dropped onto the box and is thereafter compressed with a shoe assembly. The shoe assembly includes a pair of shoes that extend from one side of the mold box to the other and have a thickness that allows them to be interleaved with the restrictor plates. The shoes are lowered to the lower edge of the restrictor plates. Simultaneously, another shoe mounted on the head plate compresses product on the other side of the divider plate so a higher level thus forming a header block having a first lower height formed beneath the restrictor plates and a second higher height formed on the other side of the divider plate.Type: GrantFiled: February 11, 1998Date of Patent: August 17, 1999Assignee: Columbia Machine, Inc.Inventor: Llewellyn L. Johnston

Patent number: 5851568Abstract: A method for consolidating powdered material to near net shape and full density is provided. The method includes the steps of: mixing a particulate material with an organic or inorganic binder to form a mold material; shaping the mold material into a mold having a shape and including an external surface and an interior cavity and being of sufficient solidity to maintain its shape yet being compressible under pressure; filling the interior cavity with a powdered material to be consolidated; heating the mold with the powdered material therein to form a heated filled mold; applying pressure to the external surface of the mold sufficient to compress the mold material and transfer a pressurizing force to the powdered material within the mold cavity so as to consolidate the powder and form an article; and removing the article from the mold. In an alternative method, the mold material is made of a particulate material which is held in the shape of the mold by a vacuum.Type: GrantFiled: July 2, 1996Date of Patent: December 22, 1998Inventor: Xiaodi Huang

Patent number: 5637332Abstract: A simple apparatus for forming a fill line in a paper beverage container such as a paper cup is disclosed. The apparatus includes no moving parts. A fill line is formed by forcing a punch of a mating ring into a finished cup positioned in a die which includes an annular recess spaced below the rim of the finished cup, the annular recess terminating in a bottom edge which serves as an anvil surface for forming the fill line. The fill line provides a user of the beverage container with a reference point for establishing a consistent measure of volume. The advantage is a simple apparatus adapted to be fitted to most paper cup finishing machines. The apparatus has no moving parts and is therefore not prone to requiring maintenance or replacement.Type: GrantFiled: November 17, 1995Date of Patent: June 10, 1997Inventor: John Ridout
