Abstract: A seal for a centrifuge for preventing material from leaking out of an effluent portion into a drive portion where the seal is disposed between a basket carrier and a drive portion, and the basket carrier is disposed between the effluent portion and the drive portion. The seal can also be disposed on a stiffener, the stiffener disposed between the basket carrier and the drive portion. A sealing arrangement for a centrifuge including a contact seal and a labyrinth disc, for preventing liquid from leaking out of an effluent portion into a product discharge outlet and for preventing material from entering into the effluent portion through the product discharge outlet. Also provided is a centrifuge incorporating the seal and/or the sealing arrangement.

Abstract: A scroll screen centrifugal separator includes a distributor that is configured to receive slurry received from a feed conduit. The distributor is configured to deflect the received slurry to a screen of the scroll screen centrifugal separator. In some embodiments, the distributor may include a distributor that has a flat surface encircled by a lip or having one or more lips positioned on the flat surface, an inclined surface, or a declined surface that faces the mouth of the feed conduit. In other embodiments, the distributor may include a plurality of dam members for defining passageways through which slurry is passable through the distributor prior to being ejected to a screen of the separator. In other embodiments, the distributor may include a distributor plate that has a plurality of radial arms attached thereto that are configured to direct slurry to the basket with a rotational velocity.

Abstract: A cigarette is equipped with a filter incorporating nanofibers. The nanofibers can be used either alone or in conjunction with other filtering media such as larger fibers, paper, activated charcoal, etc. With a nanofiber filter, the filter need not be as dense as the molecules of the smoke become attracted to the nanofiber due to quantum mechanics instead of being sieved out. The efficacy of the filter is better than filters with larger diameter fibers.
