  • Patent number: 11962578
    Abstract: A method includes receiving a first transaction request and a second transaction request including identification of a first trust action and a second trust action requested to be performed with respect to an electronic document. A first trust service provider and a second trust service provider, different from the first trust service provider, are selected to perform the requested first trust action and the second trust action, respectively. Performance of the first trust action and the second trust action on the same electronic document is coordinated with the selected first trust service provider and the second trust action provider. A first proof and a second proof are obtained confirming performance of the requested first trust action and the requested second trust action by the respective trust service providers.

  • Publication number: 20120083536
    Abstract: An adhesive composition having dispersed therein a broad spectrum antimicrobial agent for use in medical applications, such as an adhesive for surgical drapes, wound dressings and tapes, is provided. The adhesive is composed of acrylic polymers, tackifiers and a preferred antimicrobial agent, diiodomethyl-p-tolylsulfone. The subject adhesive composition may be formulated as either an essentially solventless hot melt, or as a solvent based system wherein an emulsion of the antimicrobial agent and the removal of excess solvent is avoided.

  • Publication number: 20040115274
    Abstract: An adhesive composition having dispersed therein a broad spectrum antimicrobial agent for use in medical applications, such as an adhesive for surgical drapes, wound dressings and tapes. The adhesive is composed of acrylic polymers, tackifiers and a preferred antimicrobial agent, diiodomethyl-p-tolylsulfone. The adhesive composition is essentially solventless and capable of application in a hot melt process while maintaining stability at elevated temperatures in the range of 275° F. to 350° F., which not only allows hot melt application, but allows for ethylene oxide sterilization under heat stress.
