Silt Fence Configured for Capturing Pollutants and Fabric Forming the Same
A composite silt fence configured for capturing pollutants in one embodiment comprises a silt fence fabric including i) a polymeric geotextile fabric particulate filtering layer defining the hydraulic flow capacity for the silt fence, ii) a pollutant capturing layer coupled to the polymeric geotextile fabric particulate filtering layer and configured to capture some select pollutants in water from flow that has passed through the polymeric geotextile fabric particulate filtering layer, and iii) a backing layer coupled to the pollutant capturing layer; and a plurality of stakes secured to the silt fence fabric at spaced locations. The silt fence fabric yields higher hydraulic flow than existing fence constructions with greater sediment retention and pollutant containment features.
Roofing Shingles, Tiles and Shakes
The present disclosure relates generally to roofing elements and methods for making them. In one embodiment, the disclosure provides a roofing element in the form of a roofing shingle that includes a body of a foamed cured cross-linked polymer, the body having a top surface and a bottom surface, the body extending substantially in a plane and having a thickness in the range of 0.5 mm to 35 mm; and a layer of weather-resistant roofing granules disposed on and adhered at the top surface of roofing element. The roofing element can be made by providing a body of wet foamed curable composition, and allowing the curable composition to cure to provide the body of foamed cured cross-linked polymer.
FABRIC STRUCTURE
A fabric structure includes a first layer, which is breathable and adapted to be directed toward the body of the user, a second layer, which has preferential passages for sweat in the vapor phase leading outward from the first layer, a third layer, which is breathable and arranged opposite the first layer, the second layer being between the first layer and the third layer. The first layer includes fibers of heat-conducting material.
AIRCRAFT STRUCTURAL, ANTI-BALLISTIC FLOOR PANEL
There is provided an anti-ballistic aerospace structure, said structure comprising a strike layer defining an outwardly facing surface and an opposing capture layer defining an inwardly facing surface and an intermediate structural layer arranged between the strike layer and capture layer, wherein the intermediate structural layer is spaced relative to the strike layer to define a space between the intermediate structural layer and the strike layer, said space comprising one or more reinforcement elements, and wherein the strike layer is formed of a fiber reinforced plastic laminate comprising at least one metallic layer.
MEDICAL USE VENTING FILTER
The disclosure provides improved vent filters useful in single-use in-line transfusion systems. In a first aspect, the disclosure provides filter comprising (i) a layer comprising a fluoropolymer membrane and (ii) a layer comprising at least two air-permeable thermoplastic polymeric layers, the air-permeable thermoplastic polymeric layers comprised of a first polymeric layer and a second polymeric layer, wherein the first polymeric layer is in bonded contact with the fluoropolymer membrane, possesses a melting point of about 95° C. to about 180° C., and wherein the second polymeric layer is in bonded contact with the first polymeric layer and has a melting point of about 220° C. to about 265° C. These filters exhibit excellent bonding strength between the various layers while preserving a considerable amount of the original fluoropolymer membrane air flux.
Sterilizable multilayer material
Sterilizable multilayer material (1), in particular for packaging at least one device for medical use, comprising a non-thermofusible sheet (2) sandwiched between two lower and upper thicknesses (3, 4) of thermofusible material of at least one thermofusible sheet (F), these thicknesses of thermofusible material being welded together across the non-thermofusible sheet.
Fibre reinforcement of reactive foams obtained by a moulding foam method
The present invention relates to a molding made of reactive foam, wherein at least one fiber (F) is arranged partially inside the molding, i.e. is surrounded by the reactive foam. The two ends of the respective fiber (F) not surrounded by the reactive foam thus each project from one side of the corresponding molding. The reactive foam is produced by a mold foaming process. The present invention further provides a panel comprising at least one such molding and at least one further layer (S1). The present invention further provides processes for producing the moldings according to the invention from reactive foam/the panels according to the invention and also provides for the use thereof as a rotor blade in wind turbines for example.
Building membrane with porous pressure sensitive adhesive
A breathable multilayer spun bonded polypropylene membrane having a coated pressure sensitive adhesive capable of allowing air and moisture vapor to pass through it. The adhesive is formed of a copolymer comprising a backbone of n-butyl acrylate, 2-ethylhexyl acrylate, and vinyl acetate which is mixed with a surfactant and emulsified to produce bubbles which form pores when the copolymer is set with about 80% to about 90% of the pore sizes ranging from about 200 microns to about 300 microns and a pore density in the cured pressure sensitive adhesive ranging from about 4200 per inch.sup.2 to about 4600 per inch.sup.2, said pores being uniformly distributed to form a flow path through the adhesive.
ELASTIC NONWOVEN LAMINATE WITH INELASTIC PARALLEL STRIPS
The invention relates to a nonwoven laminated web (20) for making an elastic closure element (57) of a diaper (56) or an elastic shaping element (59) at the edge (58) of a diaper (56), having at least one laminate layer (21 and 22) of nonwoven textile (21 and 22) and a laminate layer (23) of an elastic film (23) adjacent thereto, the laminate layers (21 and 22, 23) being welded to one another at numerous spots (33) in a stretched state of the film (23). During welding, the film (23) is stretched in a central region (43) transverse to the longitudinal direction (L) of the nonwoven laminate (20) and is not stretched at the two longitudinal edge strips (50) in a width of 5-25% of the total width (G) of the film (23) in each case, so that, in the relaxed state of the film (23), the nonwoven laminate (20) forms folds (44) in the nonwoven layer (21 and 22) in the central region (43), which extend in the longitudinal direction (L) of the nonwoven laminate (20), and at the longitudinal edges (50, 51) has no folds in the nonwoven layer (21 and 22) but forms there two parallel, inelastic stiffening zones, the film (23) having a smooth, closed surface structure (49) at the longitudinal edge strips (50) and a wrinkled, furrowed surface structure (47) in the central region (43).
Multilayer substrate materials for application to textile fabrics
A multilayer substrate material configured to be applied to a back surface of an upholstery or mattress textile fabric and a front surface configured to contact a user of the upholstery or mattress textile fabric. The multilayer substrate material includes protector, adhesive, film and backcoat layers. The adhesive layer is applied to the protector layer and formed of a number of discrete and non-continuous regions. The film layer is applied to the adhesive layer. The number of discrete and non-continuous regions include an interface between the protector layer and the film layer such that the protector layer touches the film layer at the interface. The backcoat layer is applied to the film layer and includes a non-acrylic binder and a flame retardant material. The number of discrete and non-continuous regions form a number of non-adhesive regions therebetween configured to not resist flexing of the protector, film and backcoat layers.
