Patent number: 10821684Abstract: A method of producing an FRP molded article, the method being suitable for producing a thick FRP molded article, includes: placing a reinforced fiber base material in a cavity of a forming mold, such that a direction in which fiber sheets are laminated together (a sheet lamination direction) is a horizontal direction; impregnating a resin into the reinforced fiber base material by injecting the resin into the cavity in an anti-gravitational direction from an injection port provided below the reinforced fiber base material placed in the cavity; applying pressure in the sheet lamination direction to the reinforced fiber base material impregnated with the resin; and curing the resin impregnated in the reinforced fiber base material.Type: GrantFiled: September 4, 2017Date of Patent: November 3, 2020Assignee: KAWASAKI JUKOGYO KABUSHIKI KAISHAInventors: Takeshi Takagi, Takahiro Ichinose, Osamu Hisamatsu, Yoshimitsu Takasugi, Shota Kida

Patent number: 10821635Abstract: A molding tool and method for producing an interior trim part. A cavity is embodied between a first element and a second element, and a slide is displaceably connected to the first element. A decorative layer is arranged on the first element and a backing is arranged on the second element. A foamable mixture is added to the hollow area between the backing and a reverse side of the decorative layer, such that a foam layer fills the hollow area. A distance between the first element and the second element is increased to enlarge the hollow area. During this process, the slide is pressed against a side facing away from the reverse side of the decorative layer, such that the hollow area is sealed with the reverse side of the decorative layer pressed against a lateral surface of the backing and/or against a lateral surface of the second element.Type: GrantFiled: May 25, 2017Date of Patent: November 3, 2020Assignee: Faurecia Innenraum Systeme GmbHInventors: Bernhard Baumann, Hugo Bonvalet, Othmane Faik, Lionel Hafer, Alain Julien, Jean Ruiz, Michael Walter

Patent number: 10799815Abstract: A filter cartridge constructed to prevent an enclosed pleated filter from collapsing into the through-bores formed in a rigid core in high differential pressure applications. The core is modified with reduced-dimension bores to reduce the area of filter material not supported by the core. Alternatively, or in addition, a semi-rigid or rigid core wrap is superposed about the core to add further structural support to the pleated filter. The wrap is formed as a webbed structure with the thickness and spacing of the webbing segments adjusted to partially occlude the underlying core though-bores. This reduces the effective cross-sectional diameter of the through-bores to reduce the overall area of the pleated filter unsupported by the core. The through-bores may have modified shapes to maintain the area of the through-bore and reduce the distance of the through-bore center point from portions of the core wall defining the through-bore. The core also may be modified with clustered through-bores regions.Type: GrantFiled: June 6, 2016Date of Patent: October 13, 2020Assignee: SAINT_GOBAIN PERFORMANCE PLASTICS CORPORATIONInventors: ZhenWu Lin, Jacob Andrews

Patent number: 10787781Abstract: A thin erosion control mattress system and method of protecting coastal structures and riverbanks against bearing failure and erosion from waves and current is disclosed. The thin mattress system includes geotextile fabric bonded to a tensile element (such as geogrid) and sand/gravel or other fill material confined in the mattress with connection elements (such as rivets) at specific intervals. The geogrid, which can be biaxial or multi-axial, provides tensile strength for picking during installation, improving foundation support and rigidity to the mattress system. The rivets function as spacers and tension elements to prevent bulging of the mattress, and are designed and spaced to temporarily secure the mattress in place for uniform filling and installation. The bonded geotextile-geogrid mat is typically sewn on all sides and filled with sand or gravel at designated fill ports. Further, a method of fabricating the thin mattress system is provided.Type: GrantFiled: September 14, 2017Date of Patent: September 29, 2020Assignee: Tensar International CorporationInventors: Jeffrey Fiske, Kord J. Wissmann
