Abstract: An apparatus (10) for welding materials has a flat anvil (12) having a width of at least two inches and a length of at least eighteen inches. A welding apparatus (14) having at least one welding head (22) is mounted on a rail (16) which is parallel to said anvil (12). The apparatus (10) may be mobile. In an illustrated embodiment, welding apparatus (14) is an ultrasonic welding unit, and apparatus (10) is used to weld thermoset materials. As illustrated, the method is used to weld thermoset plastic monofilament fabric (34) to provide a continuous method of treating the monofilament fabric (34).

Abstract: The invention relates to an apparatus and method for testing the properties of chemicals in a reaction flow stream. In the method, chemicals from the reaction flow stream are directed to the apparatus for testing the physical properties of the chemicals, which is an indication of the state of the chemical reaction. Data measured by the apparatus is stored in a computer, and the computer may be used to analyze the data and to control the reaction parameters based on the analysis of the data. The apparatus used for the analysis comprises a rheometer having an actuated shaft and a concentric container, wherein the shear properties of the material sampled in the apparatus are measured when the actuator shaft is oscillated within the container. Various unique configurations of the apparatus are described.
Abstract: A rubber tire component (10, 20, 30, 40) is laden with a mixture of fibers (12). The fibers (12) being sensitive to induction heating can be rapidly cured using a variety of methods. The preferred method permits a selective induction curing of the fiber laden component (10, 20, 30, 40) in combination with conventional curing presses.
