Patent number: 5119535Abstract: A fluid such as a fluidized bed or a molten bath, is heated to a temperature sufficiently high to soften a substantially rigid body of material and sufficiently low to avoid damage to the material. While maintaining the fluid at this temperature, the body is immersed in the fluid to heat the body uniformly. Pressure is applied to the heated body to form it into a desired three-dimensional configuration. The heated body is removed from the fluid either before, after, and/or while the pressure is applied. The body is allowed to cool and harden into its desired configuration. The body is preferably formed between a flexible member and a mold surface. The method may be used to form various types of material, including honeycomb core, laminated sheets of plastic, plastic tubing, and titanium. The body may be precut and indexed and secured to a mold which is immersed in the fluid with the body.Type: GrantFiled: September 18, 1989Date of Patent: June 9, 1992Assignee: The Boeing CompanyInventors: Clayton C. Gnagy, William L. Rodman, Ralph R. Welsh

Patent number: 4951377Abstract: A method for predeterminately sizing a core using a pair of generally opposed die means operable for compressing only an outer circumferential section of the core defined generally axially between a pair of opposite end faces of the core at least generally adjacent an outer circumferential surface thereof, respectively. A pair of sizing means are operable for disposition in confronting and predetermined radially spaced apart relation with the outer circumferential surface and a plurality of tooth tip rows defining an inner circumferential surface of the core between the opposite end faces thereof, and the outer circumferential surface and the tooth tip rows of the core are displaced generally radially inwardly thereof into sizing engagement with the sizing means thereby to effect the predetermined sizing of the inner and outer circumferential surfaces of the core in response to the compressing of only the outer circumferential section of the core by the opposed die means, respectively.Type: GrantFiled: August 4, 1989Date of Patent: August 28, 1990Assignee: General Electric CompanyInventor: Harold L. Fritzsche

Patent number: 4881430Abstract: The method of making a heterogeneous, Damascus-type cutting blade, comprising forming an open metal enclosure, placing a stack of metal foils in the enclosure, placing a metal plate in the enclosure on top of the stack of foils, folding in portions of the enclosure on said plate to compress the latter and stack of foils, heating and hammering the enclosure and foils to bond the same together, removing the enclosure from the bonded foils, and finish-griding the bonded foils.Type: GrantFiled: September 6, 1988Date of Patent: November 21, 1989Inventor: Arthur J. Hubbard

Patent number: 4856162Abstract: Bonding pressure is uniformly applied to the lay-up (70) of a bonded product (10) by the disposition of flexible, compressible, perforated sheet material (85) between the lay-up and a pair of molds (75 and 80) during the manufacture of the product by diffusion bonding.Type: GrantFiled: August 8, 1988Date of Patent: August 15, 1989Assignee: United Technologies CorporationInventors: John M. Graff, Harry A. Nutter, Jr., Leon Stoltze

Patent number: 4732031Abstract: A method of forming a deep-drawn and ironed container having a bottom profile wherein a cup is formed by drawing an inverted cup and reverse drawing the cup and simultaneously imparting a bottom profile thereto while controlling the thickness of the material in the bottom. The method also includes providing support to the profiled bottom while ironing the cup thus formed. The method is accomplished by a system which includes a draw-redraw station wherein the inverted cup is adjustably held by a fluidly actuated lift out ring and draw pad in the bottom area against a punch during reverse drawing to control metal thickness in the bottom. A separate pressure sleeve is also engaged with the profiled bottom during ironing to prevent pulling material from the bottom.Type: GrantFiled: April 20, 1987Date of Patent: March 22, 1988Assignee: Redicon CorporationInventors: Joseph D. Bulso, Jr., James A. McClung

Patent number: 4482334Abstract: A method of making a mask arrangement including two (2) or more of masks for a mask-focusing color picture tube and the mask arrangement formed by the method. A plurality of apertured flat masks, each mask comprising an effective portion having apertures and a non-effective portion surrounding the effective portion, are prepared. The flat masks are aligned and stacked, then filling material is poured into the apertures. The filling material is solidified thereby fixing the flat masks together. The fixed masks are pressed into a predetermined curved shape. Then, the filling material is removed from the apertures and the masks are separated.Type: GrantFiled: August 19, 1982Date of Patent: November 13, 1984Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventors: Yasuhisa Ohtake, Kazuyuki Seino, Eiji Kamohara
