  • Patent number: 10715475
    Abstract: A system and method for dynamic email addressing is disclosed. A proprietary mail transfer agent and processors within a proprietary environment including a persona processor enable email users to define email addresses, both in terms of which email addresses are recognized or not, and which email addresses should be organized according to persona. In another aspect, email users choose to be conditionally notified of the arrival of a new message via push notifications. Users choose to receive push notifications only for personas users deem important enough to interrupt current activity. According to an embodiment, push notifications are generated and sent via any current user communication channel.

  • Patent number: 5557950
    Abstract: A velvet fabric is produced by warp knitting on a three-bar warp knitting machine by knitting ground yarns on the machine's middle bar to provide structural and dimensional integrity to the fabric and pile yarns on the machine's top bar in extended underlaps which are shearable, nappable, brushable, or otherwise raisable to produce an upstanding raised pile. In order to resist any tendency of the pile yarn to be pulled from the fabric, the present invention contemplates that the pile yarns should be microdenier multifilament synthetic yarns while the ground yarns should also be multifilament synthetic yarns of a relatively low denier per filament not exceeding approximately 1.5 denier per filament and of a total collective denier approaching but not exceeding that of the pile yarns, preferably in excess of about 75 percent of the total denier of the pile yarns.

  • Patent number: 5542269
    Abstract: A three-bar warp knitted fabric whose technical back has both a satin-like surface and a walewise ribbed effect is produced on a three-bar warp knitting machine by knitting ground yarns on the machine's middle bar to provide structural and dimensional integrity to the fabric, knitting satin-effect yarns on the machine's top bar in extended underlaps to produce a satin-like technical back of the fabric, and inlaying elastic yarns from the machine's bottom bar in a two-in, one-out alternating pattern to create the appearance of walewise ribs in the satin-like technical back surface.

  • Patent number: 4786549
    Abstract: A warp knit Raschel fabric having unidirectional stretch characteristics and ravel resistant laid-in elastic yarns is produced by laying in two sets of spandex yarns with a set of inelastic knitted yarns. The two sets of spandex yarns cross one another at a multiplicity of contact points. The knitted fabric is subjected to dry heat in a temperature range between 385 and 400 degrees Fahrenheit with causes the two sets of spandex yarns to fuse at the contact points.
