Publication number: 20090127791Abstract: A seal assembly seals a gap between a fixed member and a rotating member housed therein, to prevent flow of oil from a first environment to a second environment of the gap. The assembly includes a first ring fitted to the rotating member, a second ring fitted to the fixed member, an elastically deformable seal attached to the second ring and comprising a first lip cooperating in a fluid-tight manner with a first mating portion of the first ring, and a spiral groove on the first lip to generate, during rotation of the rotating member, a fluid-dynamic pumping action to pump oil from a sealing area to the first environment. A second lip of the seal forms a contact seal with a second mating portion of the first ring when the rotating member is stopped, and a configuration detached from the second mating portion during rotation of the rotating member.Type: ApplicationFiled: November 5, 2008Publication date: May 21, 2009Applicant: CORCOS INDUSTRIALE DI FREUDENBERG & COSSO S.R.L.

Publication number: 20090113651Abstract: A cleaning implement that includes a connector for connecting a handle to a base block. The connector prevents the handle from rotating relative to the base block and, thus, the connector prevents the handle from unscrewing or otherwise loosening or disconnecting from the base block. The base block can include a headpiece supported between oppositely arranged shoulders, a generally cylindrical flange projecting from the headpiece, and a generally cylindrical opening extending through the cylindrical flange. A slot may be formed in an inner surface of the cylindrical flange. A ferrule that can have a generally dovetail-shaped projection provided on its outer surface can be secured to an end of the handle. The projection and the slot can form a joint when the handle is connected to the base block. This joint substantially prevents the handle from rotating relative to the base block.Type: ApplicationFiled: July 3, 2008Publication date: May 7, 2009Applicant: Freudenberg Household Products LPInventors: Robert Giacolo, Norbert Weis, David McKnight
