Expandable endovascular stent

InactiveUS20050080479A1Minimize amount of materialSubstantial longitudinal flexibility longitudinalStentsBlood vesselsStress concentrationPercent Diameter Stenosis
Disclosed herein is a tubular endovascular stent comprising a plurality of annular segments connected by one or more bridging elements. Each annular segment takes forms of periodic wavelets with a plurality of alternating symmetric peaks and valleys, preferably consisting of circular arc segments of large radii connected tangentially with straight segments to minimize stress concentration when the stent undergoes radial deformation, transverse to the longitudinal axis of the stent. The points of connection between the bridging elements and adjacent annular segments are so designed that deformations of the bridging elements remain negligible as the stent deforms radially, namely, the longitudinal dimension of the stent does not vary during the radial expansion or contraction of the stent. Hence, the radial strength and the longitudinal flexibility of the stent made according to the principles disclosed by the present invention can be independently controlled by the design parameters for the annular segments and bridging elements, without compromising the longitudinal dimensional stability of the stent. Since stress concentration and deformation in the stent can lead to restenosis, stent made from the invention disclosed here can reduce the probability of restenosis.

Method and apparatus for molding a laminated trim component without use of slip frame

An apparatus for producing a molded product from a sheet-form raw material blank has first and second mold tools that each respectively include a respective inner core mold and a respective outer edge mold laterally adjacent thereto. Drive elements drive the outer edge molds relative to a machine frame, and drive the inner core molds relative to the outer edge molds. A molding process involves closing the outer edge molds to hold an edge rim of the material blank while allowing slippage thereof, and then closing the inner core molds to three-dimensionally deform and mold a central portion of the material blank while pulling required additional material by slippage through the outer edge molds. A separate slip frame is not used. The edge rim held by the outer edge molds remains as a permanent mounting rim or flange of the finished molded product. Edge waste is minimized.

Efficient food wraps

InactiveUS20090285950A1Efficiently enclosesReduce amountBakery productsPackage designEngineering
A more-efficient edible food wrap eliminates the excess material of conventional wrap food products, providing effective containment while reducing the amount of raw materials used in production. Unused materials are thus available for additional production, extending quantities and thereby lowering producer costs. Easily fabricated on an automated or manual, multiple or individual basis, these improved structures provide easier assembly by hand or machine and selectable control of contained fluids. Further, these wrapper structures reduce collections of unconsumed food waster by including less of the often-discarded overlapped portions of wrap food products. These wrap designs are also applicable to egg rolls, pizza-like products, and other dough-based comestibles.

Leg protector

A leg protector sized to fold over the wearer's leg to cover the front side of the wearer's leg while leaving the backside of the wearer's leg exposed for easily placement and removal of the leg protector. Unlike conventional gaiters and half chaps that effectively operate as a second pant leg positioned over the pants, the adjustable strap of the insulated leg protector extends across the rear side of the wearer's leg to retain the leg protector without fully covering the backside of the wearer's leg. The arrangement allows the leg protector to be quickly put on by the wearer by draping the leg protector over the wearer's leg and secured with the adjustable strap. Similarly, the leg protector can also be removed by simply undoing the adjustable strap.

Method of manufacturing a pipe coupling component, method of manufacutring a casing structural member, and pipe coupling sturcture for a hollow part

In a first step of this method, a first intermediate product 42 having a coupling portion forming portion 16d and flat portions 21 is produced. In a second step, there is produced a second intermediate product 44 which is larger in the bending depth of the coupling portion forming portion 16d and is smaller in width of the flat portions 21 than the first intermediate product 42. In a third step, a third intermediate product 36 having the coupling portion forming portion 16d, sloping flat portions 34, and narrow flat portions 35 is produced. In a fourth step, the sloping flat portions 34 of the third intermediate product 36 are pressed obliquely upward so as to cause the material to move to the boundaries between the sloping flat portions 35 and the side walls of the coupling portion forming portion 16d, to thereby produce a fourth intermediate product 37. In a fifth step, the side walls of the coupling portion forming portion 16d, the sloping flat portions 34 and the narrow flat portions 35 of the fourth intermediate product 37 are pressed from the upper and lower sides, to thereby form a fifth intermediate product 39 in which burrs 38 are formed at the opening-side end portions of the side walls of the coupling portion forming portion 16d. In a sixth step, the burrs 38 are removed, whereby a casing structural member 16 produced. This method enables manufacture of casing structural members which can prevent leakage of fluid.
