A modular barrier includes a plurality of identical barrier sections. Each section 10 includes a base portion 12 surmounted by an upright portion 14. The upright portion has projections 16, 18 with substantially semicylindrical outer surfaces at its ends. Correspondingly shaped recesses 20, 22 are also provided. At a female end, the base portion 12 includes a nose 28. The surface of the nose is a surface of rotation of the profile of the base portion 12. At the male end, the base portion 12 includes a correspondingly shaped cavity 30. The first and second projections 16, 18 and nose 28 are provided with bores 32, 34, 36. When the female end of the barrier section 10 is brought up to a male end of a similar section, the projections mate with one another and the nose 28 is received in the cavity 30 of the similar section. A hinge pin (not shown) may then be passed through the bores 32, 34, and 36. By means of this device, one barrier section can be articulated to the next and the joint between the two base portions of adjacent barrier sections presents an essentially smooth profile irrespective of the angle between the two.

A polymer of siloxanes as flexibility monomers and strength monomers is provided. It is also provided a polymer blend that contains a polymer formed of siloxane monomers and strength monomers and another biocompatible polymer. The biocompatible polymer or polymer blend described herein and optionally a bioactive agent can form a coating on an implantable device such as a drug-delivery stent. The implantable device can be used for treating or preventing a disorder such as atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, or combinations thereof.

Disclosed are product (e.g., panels), slurry, and methods relating to an uncooked starch having a mid-range peak viscosity (i.e., from about 120 Brabender Units to about 900 Brabender Units).

A method for constructing a structure, preferably a swimming pool, includes the steps of excavating a cavity, applying a sub-base such as sand along at least a portion of the cavity, forming the sub-base into the desired shape of the structure, and applying a solidifier solution to the sub-base. The solidifier solution comprises a polymer in solution. The solidifier solution and the sub-base harden to form a smooth, hard composite layer in the base of the cavity, with the composite layer containing at least some of the polymer and at least some of the sub-base in a polymer lattice. After the solidifier solution has been applied, a liner may be installed, and the swimming pool may be filled.

A method of laser spot welding a workpiece stack-up (10) that includes at least two overlapping steel workpieces (12, 14, 150) is disclosed. The method includes directing a plurality of laser beams (24, 24′, 24″) at the top surface (20) of the workpiece stack-up to create a molten steel weld pool (92) that penetrates into the stack-up. The molten steel weld pool is then grown to penetrate further into the stack-up by increasing an overall combined irradiance of the laser beams while reducing the total projected sectional area (88) of the laser beams at a plane of the top surface of the workpiece stack-up. Increasing the overall combined irradiance of the laser beams may be accomplished by moving the focal points (66, 66′, 66″) of the laser beams closer to the top surface or by reducing the mean angle of incidence (86) of the laser beams so as to reduce the eccentricity of the individual projected sectional areas of the laser beams.

A sealing assembly has an expansion band having an arcuate band portion and a pair of threaded end portions formed at opposing ends of the arcuate band, in which the arcuate band and threaded end portions are monolithically formed as a single piece. Fixed within respective threaded end portions are a pair of oppositely threaded nuts adapted to receive a bolt having correspondingly oppositely threaded ends. Rotation of the bolt causes the threaded end portions to be simultaneously driven apart or drawn toward one another (depending on the rotation direction of the bolt) to thereby expand or contract the overall outer profile of the arcuate band portion. The monolithically formed expansion band may be made of an inexpensive, non-rusting material such as nylon 66, and glass fibers and / or additives may be employed to impart strength and flexibility.

A plasma display panel has a plasma display panel assembly for displaying an image, a chassis base coupled to the panel assembly and supporting the panel assembly, and a reinforcing member integrally formed in the chassis base so as to improve the rigidity of the chassis base. The reinforcing member is integrally manufactured with the chassis base. This structure provide improved operation efficiency and lower manufacturing cost, while maintaining the rigidity of the chassis base.

The present invention relates to a double-sided pressure-sensitive adhesive tape excellent in good balance of both flame retardance and pressure-sensitive adhesive properties, comprising a layer structure of a pressure-sensitive adhesive layer (I), a substrate, and a pressure-sensitive adhesive layer (II) in this order, in which a proportion (Y / X) of a thickness (X) of the pressure-sensitive adhesive layer (I) and a thickness (Y) of the pressure-sensitive adhesive layer (II) is more than 1.00 and less than 2.00.

A method of laser spot welding a workpiece stack-up (10) that includes at least two overlapping steel workpieces (12,14), at least one of which includes a surface coating (40), is disclosed. The method includes directing a laser beam (24) at the top surface (20) of the workpiece stack-up (10) to create a molten steel weld pool (90) that penetrates into the stack-up (10). The molten steel weld pool (90) is then grown to penetrate further into the stack-up (10) by increasing an irradiance of the laser beam (24) while reducing the projected sectional area (86) of the laser beam (24) at a plane of the top surface (20) of the workpiece stack-up (10). Increasing the irradiance of the laser beam (24) may be accomplished by moving a focal point (62) of the laser beam (24) closer to the top surface (20) or by reducing an angle of incidence (82) of the laser beam (24) so as to reduce the eccentricity of the projected sectional area (86) of the laser beam (24).

A partition panel is made of two overlaying sheets of high density polyethylene or other plastic material which have been bonded together around a perimeter and at selected regions such that the partition panel contains bonded regions where the two sheets are bonded together and hollow regions where the two sheets are spaced apart from one another. The partition panel is preferably made by thermoforming.

A dental shaping strip includes a base portion and a shaping portion. The base portion has a first base surface and a second base surface facing in an opposite direction from the first base surface. The first and second base surfaces have prescribed longitudinal lengths and prescribed widths transverse to the prescribed longitudinal lengths. The shaping portion is connected to a longitudinal edge of the base portion. The shaping portion has a first shaping surface connected to the first base surface, with at least part of the first shaping surface being abrasive. The first and second base surfaces are at least partially non-abrasive. Preferably, the first shaping surface and the first base surface diverge from each other as they approach longitudinal free edges of the dental shaping strip. Preferably, the first and second base surfaces are non-abrasive along their prescribed longitudinal lengths.
