    • A method for producing asphalt fibers includes supplying molten asphalt to a rotating asphalt spinner, centrifuging asphalt fibers from the asphalt spinner, and collecting the asphalt fibers. The molten asphalt is supplied to the asphalt spinner at a temperature within the range of from about 270.degree. to about 500.degree. F. Also disclosed is a method for integrating asphalt with reinforcement fibers including the steps of establishing a downwardly moving veil of reinforcement fibers, such as glass fibers, and centrifuging asphalt fibers from a rotating asphalt spinner positioned within the veil of reinforcement fibers to integrate the asphalt with the reinforcement fibers. A method for making an asphalt roofing shingle includes the steps of assembling together a mat of asphalt fibers with a mat of reinforcement fibers, coating the assembled mats to form an asphalt coated sheet, applying granules to the asphalt coated sheet, and cutting the asphalt coated sheet into roofing shingles. The invention also includes the asphalt roofing shingle made by this process. Further, the invention includes asphalt highway reinforcement products containing asphalt fibers, and the method of making such products.
    • 制造沥青纤维的方法包括将熔融沥青供给旋转式沥青旋转器,从沥青旋转器离心沥青纤维,收集沥青纤维。 熔融沥青在约270°至约500°F的温度范围内供应到沥青旋转器。还公开了一种将沥青与增强纤维整合的方法,包括以下步骤:建立向下移动的增强纤维面纱, 例如玻璃纤维,以及将位于增强纤维的面纱内的旋转沥青旋转器离心沥青纤维,以将沥青与增强纤维相结合。 制造沥青屋顶瓦的方法包括以下步骤:将沥青纤维垫与增强纤维垫组合在一起,涂覆组装的垫以形成沥青涂布的片材,将颗粒施加到沥青涂布的片材上,并切割涂覆有沥青的沥青 板材成屋顶板。 本发明还包括由该方法制成的沥青屋顶瓦。 此外,本发明包括含有沥青纤维的沥青路面增强材料及其制造方法。

    • A microwave transmit/receive terminal having an antenna and associated feed for receiving vertically and horizontally polarized signals and for transmitting a horizontally polarized signal employs a diplexer to be inserted between the feed and an orthomode coupler. The diplexer is formed of a cylindrical waveguide main body, a first port of which is coupled to the feed for receiving the orthogonally polarized receive signals and for coupling thereto the (horizontally polarized) transmit signal. A second port of the main body is coupled to the orthomode coupler for receiving the horizontally polarized signal to be transmitted and for coupling thereto the vertically polarized receive signals. A rectangular waveguide section is coupled to the cylindrical waveguide main body and forms a third port for coupling the horizontally polarized received signal away from said cylindrical waveguide main body. A first filter is disposed within the cylindrical waveguide main body between the first and second ports for preventing the coupling of horizontally polarized receive signals between the first and second ports. A second filter is coupled with the rectangular waveguide section for passing the horizontally polarized receive signal while preventing the coupling of the horizontally polarized transmit signal to the third port.
    • 具有用于接收垂直和水平极化信号的天线和相关馈电的微波发射/接收终端并且用于发射水平偏振信号采用双工器插入馈电和正射模耦合器之间。 双工器由圆柱形波导主体形成,其第一端口耦合到用于接收正交极化接收信号的馈电并用于与(水平极化的)发射信号耦合。 主体的第二端口耦合到正交模式耦合器,用于接收待传输的水平极化信号,并与其耦合垂直极化的接收信号。 矩形波导部分耦合到圆柱形波导主体并且形成用于将水平偏振的接收信号远离所述圆柱形波导主体耦合的第三端口。 第一滤波器设置在第一和第二端口之间的圆柱形波导主体内,用于防止第一和第二端口之间的水平极化接收信号的耦合。 第二滤波器与矩形波导部分耦合,用于使水平极化的接收信号通过,同时防止水平极化发射信号耦合到第三端口。
