  • Publication number: 20190152167
    Abstract: A tool and its method of use, where a plurality of grooves and/or a channel are formed into the tool surface of the tool. The grooves and/or channel distribute and deliver resin supplied to the tool surface throughout a dry fiber composite layup positioned on the tool surface in resin infusion and resin transfer molding. The grooves are formed in the tool surface extending to discrete areas on the tool surface to direct a flow of liquid resin to the discrete areas and infuse the dry fiber composite layup with the liquid resin at those discrete areas of the tool surface. When a channel is formed in the tool surface, a perforated plate extends over the channel to prevent fibers from the preform from being pulled from the preform and into the liquid resin flowing through the channel.

  • Patent number: 6676233
    Abstract: A storage lift includes two vertically extending tracks mounted to a wall surface such as a garage wall. The tracks guide associated sliding members through vertical motion up and down adjacent the wall. The sliding members are in turn hinged to a platform that serves in alternative embodiments as a storage platform base or a variable-height work surface, and which may also be folded compactly when not in use or during shipping. A full box framework is provided for most applications, and panels are slidable within framework grooves or brackets to fully enclose the platform. A cover may optionally be provided as required. In the preferred embodiment, an electric motor is provided within the storage platform base for motive power, and a key switch control is provided to safely actuate the motor. The electric motor in the preferred embodiment is attached to the tracks through a combination of cables and pulleys, though other techniques are contemplated.
