Patent number: 6138704Abstract: Skin friction reduction on a surface moving relative to a fluid can be obtained by ejecting a polymer-water mixture/solution into the boundary layer. The efficacy of the ejected polymer-water mixture/solution is closely related to polymer dissipation out of the boundary layer and conditioning (i.e, lengthening, unwinding or stretching) of the polymer molecules by liquid shear forces immediately before ejection. The invention is a method and apparatus for conditioning and ejecting a polymer-water mixture/solution that improves drag reduction characteristics of the mixture/solution and maintains the mixture/solution in the boundary layer for as long as possible. By improving the drag-reduction characteristics of the polymer-water mixture/solution and by extending the time it remains in the near-wall region, the ejector can increase the performance and reduce the volume and storage requirements of a drag-reduction system.Type: GrantFiled: December 31, 1998Date of Patent: October 31, 2000Assignee: Cortana CorporationInventor: Victor V.

Patent number: 6138739Abstract: An improved roll-up closure utilizing a flexible cover selected from a material suitable to effect the type of closure sought. The cover is at least as wide as the portal to be covered and is typically longer than the portal. Each lateral margin of the cover has a strip of hook or loop fastener material affixed thereto, with the complementary strip affixed to either the respective lateral margin defining the portal or to a "floating" edge of an elongated strip of flexible material attached at its opposite edge to the respective lateral margin. A first end of the cover is rigidly affixed across a first margin of the portal. The opposite end of the cover can be upturned about a transverse rod and connected to a take-up roller mounted adjacent the first margin of the portal, or it can be attached to the rod such that as the cover is raised or lowered, the cover is wound or unwound around the rod. Channel members prevent movement of the rod in a direction normal to the plane of the portal.Type: GrantFiled: January 15, 1999Date of Patent: October 31, 2000Assignee: Grant W.

Patent number: 6138740Abstract: An improved bearing mechanism with both a relative larger axial force adjustment mechanism and a relatively smaller axial force adjustment mechanism, works in conjunction with the control rod of a vertical blind system or a roller shade system to provide superior bearing and load handling capability. A primary adjustment mechanism provides a first magnitude range of urging force of a bearing structure toward a housing as by the use of an axial bolt or the like. Inasmuch as this is difficult to adjust without removal of the roller shade and such adjustment is difficult gauge physically, a secondary adjustment structure enables tension adjustment over a second magnitude range of urging force and which is accessible without having to remove the roller. The secondary adjustment structure is a wedge which operates adjacent the main tension member.Type: GrantFiled: January 8, 1999Date of Patent: October 31, 2000Inventor: Tser-Wen Chou

Patent number: 6138742Abstract: An apparatus for and method of pouring molten metal from a refractory vessel into the sprue of a mold where the vessel is in contact with the sprue. Molten metal is poured through the orifice of a nozzle in the bottom of the vessel. Laminar flow and velocity of the molten metal through the orifice are controlled by a stopper that extends from the orifice and also displaces molten metal in the sprue of the mold when the stopper is in the closed position to minimize excess buildup of solidified metal in the volume of the sprue. Filtering of dross can be accomplished in the refractory vessel and heating means can be provided to hold the molten metal at the appropriate temperature.Type: GrantFiled: December 16, 1998Date of Patent: October 31, 2000Assignee: Inductotherm Corp.Inventor: Montgomery W.
