    摘要： A molding process and apparatus suitable for use in molding processes, including rapid prototyping processes and short run production processes. The molding process and apparatus entail the use of a reconfigurable screen tool having a housing defining a manifold cavity and a plurality of substantially parallel pins, each having a head protruding from the housing and a shank protruding into the housing. The heads of the pins define a screen surface through which air is able to flow, for example, through gaps between adjacent heads or through internal passages within the pins. The process further includes axially moving the pins to configure the screen surface, preventing further axial movement of the pins relative to each other, and then drawing a vacuum within the manifold cavity and creating a vacuum at the screen surface.

    摘要： Annular brake disc preform (15), wherein 40 to 80 layers of reinforcement fibers of at least two different lengths (11, 19) ranging from 10–60 mm are distributed in a planar gradient throughout the body of the preform, with the reinforcement fibers located near the exterior planes of the disc being predominately shorter fibers (11) and with the reinforcement fibers located in the central planes of the disc being predominately longer fibers (19). Also, process of making carbon-carbon composite preforms by: providing chopped pitch or PAN fibers (11, 19) of at least two different lengths; directing a robotic spraying apparatus to spray the chopped fibers into an annular mold (5) in 40 to 80 concentric iterations of chopped fiber deposition to provide a matrix of fibers in the mold; depositing a curable binder into the mold to intermix the binder with the fiber matrix; compressing the fiber matrix and curable binder within the mold; curing the binder to form a preform matrix; filling the preform matrix with pitch to form a pitch matrix; and subjecting the pitch matrix to chemical vapor deposition to form a carbon-carbon composite preform (15).

    摘要： A single endless series of steps for up and down flights has inboard end spacing control links, each operated by a gear arrangement at transitions between curved and straight paths of step travel. Steps are molded plastic cores with top mounted tread caps, both the cores and caps being of colors as desired, and with light transmission characteristics from opaque to transparent, as desired. Inter-engaging edges on treads and risers are of curved shape facilitating the transition from straight to curved runs of steps. Break-away stripper comb fingers at landings terminate escalator operation when an object becomes jammed between a step and a finger and breaks a finger. Spring-loaded skirt guards at the sides of steps, and step spacing monitors, include wear indicators. The ascending and descending flights of steps are supported by structural tubes extending between floors, with no other support for the flights. Stabilizer legs, rollers and tracks under the steps maintain the horizontal attitude of the steps. Escalator drive is by belt and rack through the links in one embodiment, and by individual motor-gear sets in the steps driving on stationary curved racks in the other embodiment.
