Multi-Layer Visor System for Surgical Hood
A multi-layer visor system for a surgical hood or garment is provided. The system includes a base film layer and one or more removable film layers that are coextruded at high temperature to form a sterile surface between each of the film layers should the surgeon elect to peel away a soiled or splattered removable film layer during the course of a surgical procedure so that an unobstructed view can be maintained. Thus, no separate sterilization step is required in order to sterilize the layers of the visor system. Each of the removable film layers can additionally include a tab having distinctive features in order to enable a wearer to easily distinguish between the tabs in order to make it easier for a wearer to know which tab to pull first to remove the outermost removable film layer. Further, because the tabs are located about the perimeter of the removable films, viewing is not obscured, yet the film layers are held securely in place until easily removed from the underlying removable film layer or base film layer.

The sealing tube may comprise at least one inlet for inserting a substance into the sealing tube. Each of the plurality of straps may have two ends that are both attached to the top edge of the apron wall on opposing sides of the apron wall.
METHOD FOR PROTECTING LOW-E GLASS PLATE, METHOD FOR PRODUCING GLASS UNIT, LAMINATE AND PROTECTIVE SHEET FOR LOW-E GLASS PLATE

Method of producing metal member, method of producing resin member, and method of producing exterior part
Provided are a method of producing a metal member, a method of producing a resin member, and a method of producing an exterior part of a vehicle, each using a laminated body including a paint substitute film that includes a thermoplastic resin film, a colored layer, and a semi-cured hard coat layer, in this order, and a protective film that is bonded to a surface of the semi-cured hard coat layer. (1) The method of producing a metal member uses a steel plate together with the laminated body, and includes: a molding step of performing thermocompression bonding on the laminated body and the heated steel plate and performing press-molding while curing the semi-cured hard coat layer. (2) The method of producing a resin member uses a molten resin together with the laminated body, and includes: inserting the laminated body into a mold; performing in-mold molding by performing injection-molding using the molten resin; and curing the semi-cured hard coat layer after the insertion into the mold and until the in-mold molding ends. (3) The method of producing an exterior part of a vehicle includes combining the metal member produced by the above-described method, and the resin member produced by the above-described method.
Protective film
A protective film of the present invention is used at the time of performing heat bending on the resin substrate, and includes a base material layer and a pressure sensitive adhesive layer adhered to a resin substrate, in which the base material layer includes a first layer which is positioned on an opposite side of the pressure sensitive adhesive layer and has a melting point of 150° C. or higher, and includes a second layer which is positioned on a pressure sensitive adhesive layer side and has a melting point of lower than 150° C., the pressure sensitive adhesive layer has a melting point of lower than 150° C., and MFR of a thermoplastic resin contained in the second layer, which is measured in conformity with JIS K7210, is in a range of 0.5 g/10 min to 4.0 g/10 min.
Personal armor resistant to sharp or pointed weaponry
According to exemplary inventive practice, a personal armor system includes a textile-based layer not exceeding ½-half-inch thickness, and an elastomeric coating not exceeding ⅛-inch thickness. The textile-based layer includes a fiber reinforcement and a resin binder. The combined areal density of the textile-based layer and the elastomeric coating does not exceed 2.5 psf. According to a first mode of inventive practice, the elastomeric coating is essentially a strain-rate-sensitivity-hardening elastomer, and the areal density of the textile-based layer does not exceed 2.3 psf. According to a second mode of inventive practice, the elastomeric coating is essentially a microparticle-filled strain-rate-sensitivity-hardening elastomeric matrix material, and the areal density of the textile-based layer does not exceed 1.7 psf. The microparticles (e.g., spherical glass microparticles) do not exceed, by weight, 30 percent of the strain-rate-sensitivity-hardening elastomeric matrix material. The textile-based layer affords ballistic protection; the elastomeric coating affords protection against sharp/pointed objects.
