Abstract:
In an olefin series flooring material according to the present invention, a printed layer 4 containing synthetic resin is laminated on a lower surface of a surface resin layer 2 containing olefin series resin, and a base material layer 3 containing olefin series resin is integrally laminated on a lower surface of the printed layer 4 via an adhesive layer 5. The adhesive layer 5 contains carboxylic acid denaturation propylene-1-butene copolymer resin and carboxylic acid denaturation propylene-ethylene-1-butene copolymer resin, and a mass ratio of the carboxylic acid denaturation propylene-1-butene copolymer resin/the carboxylic acid denaturation propylene-ethylene-1-butene copolymer resin falls within the range of 55/45 to 95/5. According to this olefin series flooring material, sufficient adhesive strength for the printed layer can be obtained.

Abstract:
The present disclosure provides a contact lens package containing a contact lens in a compressed state. In one exemplary embodiment, the overall internal depth of the package is less than the natural sagittal depth of the contact lens. Different single-use contact lens package shapes and configurations may be used. In some embodiments, a spring disc is included in the packages to help present the contact lens to the user when the package is opened. The contact lens packages may be adhered or clipped to a card or other carrier sheet, and may be housed in a number of different secondary packages.
Abstract:
A ballistic and/or fire barrier for protecting objects in an interior of a vehicle due to projectile penetration and/or fire includes one or more layers of high strength fabric positioned towards an outer shell of the vehicle. The high strength fabric is substantially fixedly or fixedly positioned with respect to the outer shell of the vehicle. In another embodiment, the ballistic and/or fire barrier protects objects in a structure from damage due to projectile penetration. The ballistic and/or fire barrier includes at least one layer of high strength fabric positioned towards an outer housing of the structure. The high strength fabric is substantially fixedly positioned with respect to the structure towards either the inner or outer surface of the outer housing. In another embodiment of the present invention, a ballistic barrier protects a wearer of the ballistic barrier from damage due to projectile penetration. The ballistic barrier comprises first and second portions positioned generally parallel each other. The first portion includes one or more layers of high strength fabric while the second portion is generally impact-resistant. Preferably, the layer of high strength fabric comprise a plurality of plies. One of the plies can comprise woven fibers. Another of the plies can be a felt. Also preferably, the layer of high strength fabric in the ballistic barrier embodiments comprises a polymer material such as one or more of aramid material, polyethylene material, and polybenzoxazole material.
Abstract:
A synthetic grass assembly for installation on a supporting soil substrate includes a pile fabric with a flexible sheet backing and rows of upstanding synthetic ribbons representing grass blades, extending upwardly from an upper surface of the backing. An infill layer of two distinct graded courses of particulate material is disposed interstitially between the upstanding ribbons upon the upper surface of the backing and of a depth less than the length of the ribbons. A bottom course of intermixed hard sand and resilient rubber granules with substantially identical particle size distribution characteristics is installed upon the backing and a top course exclusively of resilient rubber granules is placed upon the bottom course.
Abstract:
A method of producing a polyurethane foam sheet, and a laminated sheet that uses such a foam sheet, that can be applied to artificial leather, synthetic leather, and cushioning materials used in all manner of applications. A polyurethane foam sheet is produced by applying a liquid mixture, obtained by mixing together a heated and melted hot melt urethane prepolymer (A) containing isocyanate groups at molecular terminals, and a compound (B) containing at least 2 active hydrogen atom-containing groups, onto a substrate in a sheet-like manner, and then water foaming the liquid mixture by bringing the sheet-like liquid mixture into contact with water vapor or moisture (water). A laminated sheet is produced by bonding a third substrate to the polyurethane foam sheet.

A method of manufacturing a low-density clad steel sheet, including: preparing a base material, a lightweight steel sheet including C: 0.3 to 1.0%, Mn: 4.0 to 16.0%, Al: 4.5 to 9.0%, and Fe; preparing cladding materials, each being martensitic carbon steel including C: 0.1 to 0.45%, Mn: 0.1 to 3.0%, and Fe; disposing the base material between the cladding materials to obtain a laminate; welding an edge of the laminate, and heating the welded laminate to 1050 to 1350° C.; finish-rolling the heated laminate to 750 to 1050° C. with a rolling reduction ratio of 30% or more in a first pass, to obtain a hot-rolled steel sheet; coiling the hot-rolled steel sheet at 400 to 700° C.; applying a cold-reduction ratio of 35 to 90% to obtain a cold-rolled steel sheet; and annealing the cold-rolled steel sheet at 550° C. or higher and A3+200° C. or lower of the cladding materials.
Abstract:
A system that receives nanomaterials, forms nanofibrous materials therefrom, and collects these nanofibrous materials for subsequent applications. The system include a housing coupled to a synthesis chamber within which nanotubes are produced. A spindle may extend from within the housing, across the inlet, and into the chamber for collecting nanotubes and twisting them into a yarn. A body portion may be positioned at an intake end of the spindle. The body portion may include a pathway for imparting a twisting force onto the flow of nanotubes and guide them into the spindle for collection and twisting into the nanofibrous yarn. Methods and apparatuses for forming nanofibrous are also disclosed.
