  • Patent number: 11208564
    Abstract: The present invention relates to an impregnation process for a functional fibrous substrate, a liquid composition for implementing this process and the obtained impregnated fibrous substrate. The impregnated functional fibrous substrate is suitable for manufacturing mechanical or structured parts or articles. In particular the present invention deals with an industrial process for impregnating a functional fibrous substrate or long functional fibers with a viscous liquid composition containing mainly monomer components. This viscous composition is called hereafter liquid monomer syrup. The invention concerns also a functional fibrous substrate pre-impregnated with said syrup which is useful for manufacturing mechanical or structured parts or articles. More particular the impregnation of functional fibrous substrate with the monomer syrup is achieved in a mould.

  • Patent number: 11157888
    Abstract: Embodiments of the disclosure enable a computing system to enhance one or more financial transactions. The computing system identifies a cardholder account used to enter into a financial transaction, identifies a merchant and/or a primary product associated with the financial transaction, analyzes cardholder data associated with the cardholder account and account data associated with the merchant and/or the primary product to determine a secondary product, generate presentation data for presenting product information associated with the secondary product, and receive selection data associated with the secondary product such that the financial transaction is enhanced with the secondary product. Aspects of the disclosure provide for enhancing the financial transaction with a secondary product tailored to the cardholder, provided or promoted by the merchant, and/or useable with the primary product in a constructive, complementary, and/or effective manner.
