摘要： The invention provides intimate physical mixtures of macrocyclic polyester oligomer (MPO) and filler, as well as methods for their preparation and use. Improved dispersion of filler in a polymer matrix is achieved upon polymerization, and larger amounts of filler with high aspect ratio can be used. In one aspect, the invention provides mixtures of MPO with magnesium silicate. In another aspect, the invention provides a mixture of MPO, filler, and polymerization catalyst as a one-part, ready-to-polymerize material with a long shelf life. The one-part material can be used, for example, in the manufacture of parts without modification of existing processing equipment.

摘要： The vehicle (10) includes a frame (12) having at least three non-circular wheels (20, 22, 24) secured to a frame (12), wherein the wheels are mechanically secured to each other so that whenever one non-circular wheel moves, the other wheels (20, 22, 24) move. An offset arm (76) powered by a motor (78) rotates a weight (84) around a geometric center adjacent the wheels to sequentially tip them so that their sequential tipping moves the vehicle (10). The non-circular wheels (20, 22, 24) are sequentially aligned with respect to each other so that whenever one wheel is tipped from a collapse alignment (32) into a contact alignment (34), sequentially the next non-circular wheel (20, 22, 24) is moved into a collapse alignment (32). Any driving force may be used to sequentially tip the non-circular wheels (20, 22, 24, 26), instead of the rotating weight (84).

摘要： Large composite structures are produced using a vacuum assisted resin transfer molding process. The structures incorporate cores, which may be hollow cells or foam blocks. A plurality of cores, each of which may be wrapped with a fiber material, is arranged in a layer on a mold with a fiber material arranged to form face skins. The assembly is sealed under a vacuum bag to a mold surface. One or more main feeder conduits are provided in communication with a resin distribution network of smaller channels which facilitates flow of uncured resin into and through the fiber material. The resin distribution network may comprise a network of grooves formed in the surfaces or the cores and/or rounded corners of the cores. The network of smaller channels may also be provided between the vacuum bag and the fiber material, either integrally in the vacuum bag or via a separate distribution medium. Resin, introduced under vacuum, travels relatively quickly through the main feeder channel(s) and the network of smaller channels. After penetrating the fiber material to reach the surface of the cores, the resin again travels relatively quickly along the cores via the grooves in the cores or the spaces provided by the rounded corners to penetrate the fiber material between the cores, if present, and between the cores and the mold.

摘要： In one aspect, the invention relates to processes for producing substantially free-flowing shapes of macrocyclic oligoester, wherein the freshly-shaped macrocyclic oligoester is maintained at elevated temperature for a sufficient time. In certain embodiments, the shapes are heated in water, thereby avoiding agglomeration during the heating process itself. In another aspect, the invention relates to processes for removing solvent from a solution of macrocyclic oligoester using elevated temperature, reduced pressure, or both, thereby obviating the need for an anti-solvent to precipitate the macrocyclic oligoester from the solution. Other aspects of the invention related to shaping of macrocyclic oligoesters are presented as well.

摘要： The invention provides blends of macrocyclic polyester oligomer (MPO) with high-molecular-weight polymer and polymerization catalyst as friable, one-component, ready-to-polymerize materials with long shelf life. The invention also provides methods for preparation and use of the blend materials. The blends are used, for example, in the production of thermoplastics via low-pressure processes, such as rotational molding and powder coating, without modification of existing equipment. The blends are particularly useful where it is desired to exploit the ability to polymerize and crystallize MPO isothermally, but where the melt viscosity of unfilled MPO is too low for use in existing equipment.

摘要： A method for reducing broken fibers on the surface of a carbon fiber bundle involves passing the yarn past a suction nozzle having an extended trailing edge which impacts the broken fibers as they pass the slot breaking off the fibers. The broken fibers are transported to a disposal station. The differential in elevation of the leading and trailing edges of the intake slot of the nozzle provide an exposed impacting edge.
