    摘要: An anti-siphon device for an inlet check valve includes a plurality of contoured ribs, which prevent a siphoning hose from entering a fuel tank interior through the inlet check valve. Moreover, the ribs permit liquid fuel to pass substantially unimpeded such that an adverse pressure change is not induced in the inlet check valve.

    摘要: A composition comprising a polymer comprising a repeat unit of Formula I: wherein R1 is independently in each occurrence H, C1-40 hydrocarbyl or C3-40 hydrocarbyl containing one or more S, N, O, P or Si atoms, or both of R1 together with the 9-carbon on the fluorene, may form a C5-20 ring structure which may contain one or more S, N, or O atoms; R2 is independently in each occurrence C1-20 hydrocarbyl, C1-20 hydrocarbyloxy, C1-20 thioether, C1-20 hydrocarbyloxycarbonyl, C1-20 hydrocarbylcarbonyloxy, or cyano; a is independently in each occurrence, 0 or 1; X is O, S, SO2, C(R3)2 or N—R3 wherein R3 is aryl or substituted aryl of C6 to C40, aralkyl of C6 to C24, or alkyl of C1 to C24. Preferably R3 is aryl of C6 to C24 and more preferably R3 is an alkylated aryl group of C6 to C24; Ar is an aryl or heteroaryl group of C6 to C40 or substituted aryl or heteroaryl group of C6 to C40, preferably C6-C24, and most preferably C6-C4. Y is a conjugated moiety that can vary in each occurrence of the repeat unit.
