  • Patent number: 6637079
    Abstract: The present invention provides a female component for engaging a complementary hook component in a refastenable fastening device. The female component of the present invention is capable of engaging a hook component that has flexible, resilient individual hook elements. The female component comprises at least two, and preferably three zones or layers. Each zone has certain of the desired individual characteristics for entangling and holding the hooks of the mating hook component. These include a first zone for admitting and engaging at least some of the hooks of the complementary hook component (the “entanglement” zone), a second zone for providing space for the hooks to occupy after they have been admitted by the entanglement zone (referred to as the “spacing” zone), and a backing adjacent to the spacing zone for providing a foundation for the entanglement and spacing zones.

  • Publication number: 20020046183
    Abstract: Methods and apparatus for authentication of postage indicia are disclosed. A secret key is read from store and modified in dependence upon postage data to be printed in a postage indicium. The modified key is then utilised to generate an authentication code dependent upon the postage data to be printed. Authentication of the indicium is effected by reading the authentication code and postage data from the printed indicium and repeating the process of generating an authentication code. The generated authentication code is compared with the authentication code read from the indicium. A control code based on a value in an accounting register may be included in the indicium. The value may be a value of postage dispensed in a determined expired period.

  • Patent number: 6306810
    Abstract: Provided are aqueous hard surface cleaning and disinfecting composition which comprises the following constituents: (a) at lease one cationic surfactant having germicidal properties; and (b) a fluorosurfactant selected from the group of nonionic fluorosurfactant, cationic fluorosurfactant, and mixtures thereof, and (c) a film-forming, organosilicone quaternary ammonium compound. Optionally the compositions may further include (d) one or more detersive surfactants particularly selected from carboxylate surfactants, as well as nonionic, cationic and amphoteric surfactants, (e) one or more organic solvents, and further conventional additives. The compositions provide good sanitization of hard surfaces, and good cleaning notwithstanding the surprisingly low amount of fluorosurfactant present.
