    摘要： An interlocking support structure has an array of rectangular cells arranged in at least one layer, each cell having four sides, opposite ends, and eight corners, and sharing common sides and corners with any adjacent cells. The cells are formed by sets of spaced, parallel elongate members extending in x, y and z directions, with the x, y and z members interlocked with one another at the corners of the cells to form interlocking corner joints. Each structural member is hollow at least in the vicinity of each corner joint with which it intersects, and communicates with the other structural members at the respective corner joints. A plug of hardened, initially flowable material fills the hollow interior of the interlocking structural members at least at the corner joints and adheres to the internal surfaces of the members at the corner joints to secure the members together at each corner in the rectangular array.

    摘要： A gear switching mechanism for a printing machine comprises at least one pair of input and driven gears, each pair rotationally mounted on a corresponding common axle. The input gear of each pair may be coupled to a common drive, while each driven gear is coupled to a separate output. A rotational gear coupling is mounted to translate along each axle to selectively engage and disengage the corresponding pair of input and driven gears. The rotational gear coupling includes a cam follower that slides along a cam profile of a cam shuttle. The shuttle defines a cam profile that is normal to the common axles. In one embodiment, the cam shuttle translates linearly, while in another embodiment, the shuttle rotates. The cam profile is configured to selectively engage and disengage the rotational couplings of each pair of input and driven gears.

    摘要： A method of manufacturing a composite panel includes manufacturing a composite panel having a first skin, a second skin, a core, and a plurality of distinct groupings of Z-axis fibers that extend through the core from the first skin to the second skin, wherein the Z-axis fibers include opposite ends respectively terminating at and integrated into the first skin and the second skin; and creating structural stringers in the composite panel by removing the second skin and substantially all of the core and the Z-axis fibers down to or adjacent to the first skin.

    摘要： A method of inserting z-axis reinforcing fibers into a multi-layer composite laminate. Layers of material made up of z-axis fiber and y-axis fibers are automatically transported into a z-fiber deposition machine having a housing with upper and lower surfaces. Z-axis apertures are formed in the respective upper and lower surfaces. An elongated solid rod having a tapered front tip is aligned in close proximity to the aperture n the bottom surface. The rod is first rotated by a motor and then actuated upwardly completely through the thickness of the layer of x-y material by an actuator. A first hollow tube having a z-axis is axially aligned with the aperture in the top surface and a fiber bundle is threaded downwardly through a first hollow tube to a position adjacent its bottom end. The z-fiber deposition machine has structure to feed a predetermined length of the fiber bundle downwardly through the first hollow tube so that it follows the pathway in the x-y material formed by the rod which is now withdrawn downwardly through the aperture in the bottom wall. The z-axis fiber is thus deposited into the x-y material. The top end of the z-fiber is then severed and the x-y material is then advanced a predetermined distance to complete the cycle and is thus set to be repeated.
