A deflection member that includes a reinforcing member and a plurality of tiles fastened to the reinforcing member.

A stitchless highly oriented polypropylene fabric bulk bag of the type that can hold 500 to 5000 pounds (226.7 to 2268 kilograms) of bulk material includes a highly oriented polypropylene fabric top, body and bottom, with a heat fused joint providing an air tight connection between the top and body, and another air tight heat fused joint connecting the body and bottom. A fill spout and discharge tube may also be provided with an air tight heat fused joint connecting the fill spout to the top and another air tight heat fused joint connecting the discharge spout to the bottom. Heat sealing machinery include heat seal bar assemblies that can self-align during heat-sealing to apply even pressure to all areas being heat sealed. A heating element is of single piece construction and can include end coupler portions as part of the single piece construction. Carrier plates used in a heat-sealing assembly line guide parts placement, provide quality checks for parts placement, and tooling set-up for machinery.

A composite article has an interior layer comprising a natural fiber and an exterior layer injection molded onto the interior layer. The exterior layer forms an outer surface over the interior layer. A method of forming the composite article includes providing a base layer comprising a natural fiber and providing a first tool and a second tool. The first and second tools are configured to cooperate to form a cavity therebetween. The first tool has an injection molding channel formed therein. The base layer is inserted into the cavity between the first and second tools and pressed into a desired shape. A liquid polymeric material is inserted through the injection molding channel of the first tool and onto a surface of the base layer to form an injection molded layer of the polymeric material on the base layer.

Protective coverings herein have a coated woven material with a first edge parallel with a warp direction and a second edge opposite the first edge, and have a first edge band proximate the first edge and a second edge band proximate the second edge. The coated woven material has a woven scrim made of a plurality of weft tapes and a plurality of warp tapes, but the warp tapes positioned in the first and second edge bands are high-shrinkage warp tapes and the warp tapes positioned in between the first and second edge bands have a shrinkage that is less than a shrinkage of the high-shrinkage warp tapes, and has a coating on at least one major surface of the woven scrim. The plurality of high-shrinkage warp tapes shrink upon application of heat. Methods of covering a load, such as stacked lumber, with the protective covering are also disclosed.

Crown reinforcement of an aircraft tire comprises a working reinforcement (2) radially inside of tread (3) and radially outside of carcass reinforcement (4). Working reinforcement (2) comprises two working bi-plies (21, 22) radially superposed with respective axial widths (L.sub.1, L.sub.2), from first axial end (I.sub.1, I.sub.2) to second axial end (I.sub.1, I.sub.2). Each working bi-ply (21, 22) comprises two working layers (211, 212; 221, 222) radially superposed and respectively made up of axially juxtaposed portions of strip (5) of axial width W extending circumferentially in periodic curve (6) that forms, in the equatorial plane (XZ) of the tire and with the circumferential direction (XX) of the tire, a non-zero angle A and has a radius of curvature R at its extrema (7). The difference DL between the respective axial widths (L.sub.1, L.sub.2) of the radially superposed working bi-plies (21, 22) is at least equal to 2(W+(RW/2)(1cos A)).

A life ring includes a cover formed of a knitted back polyester fabric with a top vinyl coating, and a urethane foam core within the cover. The cover and the urethane foam core are formed into a ring shape. By using the noted cover material, the life ring can be manufactured without a painting step, thereby reducing manufacturing costs and improving the consistency of the finished product.

A high-ageing-stable planar sheet for the building sector and to the use of a high-ageing-stable planar sheet in the building sector, in particular as a sarking sheet, underlay sheet and/or sheathing sheet in a roof construction and/or a faade sheet in a wall construction.

Radiation shielding performs a range of functions determined by the type and number of layers of materials used, thickness, weight, and structural support afforded by the radiation shielding. A radiation shield laminate stack may be constructed consisting of a plurality of layers of ultra-high molecular weight (UHMW) polyethylene, polyethylene film, and carbon fiber, which is held together with an epoxy. The carbon fiber lay may be coated with nanoparticles of Boron (B) or Boron Nitride (BN), Boron Oxide (B.sub.2O.sub.3) or Boron Carbide (B.sub.4C) or a combination thereof to increase the shielding properties of the laminate stack. The radiation shield is lighter than aluminum, structurally sound, and thus may be used in the space environment to effectively block Galactic Cosmic Rays, atomic oxygen and UV radiation.
