摘要： Polar silane linkers are provided that attach to resins to form silane-functionalized resins. The functionalized resins can be bound to hydroxyl groups on the surface of silica particles to improve the dispersibility of the silica particles in rubber mixtures. Further disclosed are synthetic routes to provide the silane-functionalized resins, as well as various uses and end products that benefit from the unexpected properties of the silane-functionalized resins. Silane-functionalized resins impart remarkable properties on various rubber compositions, such as tires, belts, hoses, brakes, and the like. Automobile tires incorporating the silane-functionalized resins are shown to possess excellent results in balancing the properties of rolling resistance, tire wear, and wet braking performance.

摘要： An air inlet deflector for a structure having an air inlet. The deflector may be retractable within the structure, may be integrally formed with the structure, and may prevent the structure from ingesting foreign matter, such as birds. The deflector may include a series of ribs, spokes, or vanes that may vary in width and/or thickness from fore to aft, and/or may be curvilinear in one or more planes of view, and/or may serve double duty as inlet vanes for redirecting inlet air.
