    Abstract: In a bicycle frame comprising a plurality of frame members which are selectively joined together at the ends thereof, each of the joints which support the head tube, the seat and the crank housing is a lug joint comprising a plurality of organic fiber layers partially wrapping the joined end portions of the frame members, the fibers composing each layer being oriented at different angles from the fibers in the adjacent layers, and all of these sheets being impregnated with resin which hardens to secure the sheets to the frame members. Web portions of these fiber layers also enclose a portion of the space between wrapped portions of the frame members, and each of these spaces is filled with a suspension of microballoons in hardended resin which cooperates with the web portions of the fibers layers to brace the joined frame members against movement toward each other during use of the bicycle. The production of bicycle frame in accordance with the invention is expedited by utilizing, as the resin component of each joint, a two-part resin which sets by exothermic reaction at room temperature and thus eleminates need for heat treatments such as are required in the case of thermosetting resins, brazing and other such manufacturing procedures.

    Abstract: A polycondensation reactor for processing low viscosity polyester or another polymer into relatively highly viscosity polymer comprises a substantially cylindrical horizontal reactor vessel with a polymer inlet and a polymer outlet adjacent its opposite ends and a vapor exhaust opening in the upper side of the vessel at its outlet end. A polymer agitator is rotated axially within the chamber and includes plural alternating annular overflow and underflow baffles and multiple perforated film-forming screens disposed therebetween in parallel spaced relation to one another. The overflow baffles are in peripheral polymer-sealing relation to the vessel while the underflow baffles have multiple underflow recesses in their outer peripheries, whereby the baffles define a tortuous polymer flow path alternately through their respective polymer overflow and underflow openings to control residence time, distribution and viscosity growth as the polymer flows between the baffles. The baffles and screens are integrally fixed coaxially at their outer peripheries by axially extending wiper bars. Aligned openings in the baffles and screens along the rotational axis of the agitator provide for free flow of volatiles to the exhaust opening.
