  • Patent number: 11155012
    Abstract: In a method of manufacturing a seal assembly, strips of material are extruded to form first and second bodies, and ends of the bodies are positioned into a mold cavity of a molding apparatus. An elastomeric material is injected into the mold cavity to form a locator device having a foot portion and a tab portion with the tab portion defining a first reference point. A thermoplastic elastomeric material is injected into the mold cavity to form a corner mold covering the body ends and the foot portion of the locator device with the corner mold defining a second reference point. The corner mold bonds the first body end, the second body end, and the locator device together to fix the locator device to the first body end at a locator position such that a predetermined distance between the reference points is maintained during injecting of the thermoplastic elastomeric material.

  • Patent number: 11130295
    Abstract: Presented are manufacturing control systems for fabricating composite-material structures, methods for making/operating such systems, and resin transfer molding techniques for ameliorating race-tracking effects in fiber-reinforced polymer panels. A method for forming a composite-material construction includes confirming, via a system electronic control unit (ECU), that a fiber-based preform is placed in a mold cavity and that opposing mold segments of the molding apparatus are sealed together. A filler, such as a compressible bladder, a cluster of spring-biased pins, or a spray-chopped fiber bed, is introduced into a void between the fiber-based preform and a tool face of one mold segment to thereby eliminate an unwanted resin race track. The system ECU commands a resin pump to inject resin through a primary gate of the molding apparatus and into the mold cavity to thereby impregnate the fiber-based preform with the resin. One or more vents operate to evacuate air from the mold.

  • Patent number: 11103395
    Abstract: A technique for capturing a three-dimensional digital image of a customized shape for a wheelchair seat and back and subsequently producing a seat and back from the image. The captured image may include one or more datum points therein to provide a reference plane for the seat and back. The datum points may be in a color-coded layer located relative to the bottom edge of the seat. The color code may indicate the size of the user and seat at a coarse level. The customized shape may be captured from a shape capture bag or bags that capture one or both of the shape of the user's back and bottom. The shape capture bag used to capture the shape of the user's bottom, for use in manufacturing the seat, may be enhanced by a pre-formed layer that contains a contour or one or more components that together form a contour that biases the shape capture bag toward the shape of the user's bottom when gravity is acting upon the user to sink into a cushioned seat.
