A synthetic nonwoven fabric having bonded fibers forming channels surrounding unbonded fibers forming raised slip resistant spots. The fabric is made by extruding hot polymer through a spinneret die onto a moving belt to form a sheet of random fibers, which sheet undergoes a calendering process between a pair of heated rollers, one of which rollers having a plurality of cavities defined in its surface. The resulting fabric can be laminated and otherwise combined with other layers as desired to provide an end product having good slip resistant properties.

The present invention relates to a pig for use in a system for lining ducts such as water or sewage pipes or electrical ducts or gas pipes. The pig is insertable at least partly within a fabric liner sleeve located in a duct such as a water or sewage pipe and is capable of heating the liner sleeve in situ in the duct to melt or soften thermoplastic material of the liner sleeve to subsequently form, on cooling of the melted thermoplastic material, a rigid liner in the duct. A pig for fitting a liner to the inside of a pipe, comprising a pig body defining a longitudinal axis in a longitudinal direction from a front portion to a rear portion; a gas supply port in the front portion; a gas outlet diffuser forming part of the rear portion; a heating chamber in the pig body forming a flow path from the fluid inlet to the outlet diffuser; and a heater within the heating chamber, wherein the outlet diffuser comprises a plurality of channels, each channel comprising an inlet facing the front portion in the longitudinal direction and an outlet extending radially outwardly from the longitudinal axis.

A layered sheet 10 includes a substrate layer 1, and surface layers 2 and 3 configured to be layered on at least one surface of the substrate layer 1. The substrate layer 1 contains a first thermoplastic resin and inorganic fillers. The surface layers 2 and 3 contain a second thermoplastic resin and a conductive material. A content of the inorganic fillers in the substrate layer 1 is 0.3 to 28 mass % based on a total amount of the substrate layer.

A repulpable insulated container assembly having a container formed of paper such as corrugated cardboard or varying paper materials and defining an interior; and a repulpable insert placed within the interior of the container and formed of a first paper layer; and a paper fiber pad coupled to the first paper layer.

This invention relates to tufted floorcovering articles that are washable in commercial, industrial, and/or residential washing machines. In particular, this invention relates to modular carpet tiles that are constructed in such a way as to withstand exposure to at least one wash cycle in an automatic washing machine. The carpet tiles are designed to be soiled, washed, and re-used, thereby providing ideal end-use applications such as entryway floorcovering articles. A further advantage includes the ability to print advertising logos on the carpet tiles and easily change out the advertising logos as desired. Both features of the carpet tile of the present invention are achievable, at least in part, because the surface of the tile that contacts the floor does not require any type of adhesive in order to use the carpet tile for its intended function.

A method may comprise: laying up a first plurality of plies of material comprising thermoplastic resin and fiber to form an inner skin preform, the inner skin preform being a continuous sheet including alternating peaks and valleys; laying up a second plurality of plies of material comprising thermoplastic resin and fiber to form an outer skin preform; and joining the inner skin preform to the outer skin preform.

A method for forming a fiber-reinforced thermoplastic control surface may comprise: stacking plies of thermoplastic composite sheets to a first desired thickness to form a first skin; stacking plies of thermoplastic composite sheets to a second desired thickness to form a second skin; forming the first skin in a first contour; forming the second skin in a second contour; forming a stiffening member including a thermoplastic resin, the stiffening member including a shape having a plurality of peaks and troughs; assembling the stiffening member between the first skin and the second skin; and joining the stiffening member to the first skin and the second skin.

A device for laminating a substrate with a thermoplastic coating material has an IR heating device for melting a surface of the coating material, an opposite cooling apparatus which actively cools the opposite surface of the coating material, and at least one press-roller assembly, which presses together the substrate web and the coating material to produce a hot-melt adhesive bond. In order to prevent any irregularities in the finished product, the cooling apparatus is designed as a rotatably driven cooling roller, over the circumference of which the following are arranged in succession: a feed apparatus for the thermoplastic coating material, one or more IR radiant heaters for heating the surface of the thermoplastic coating material resting on the cooling roller, a feed apparatus for the substrate web, one or more press rollers for pressing the substrate web against the coating material, and a removal apparatus for the laminated product.

A method to provide for an enameled glazing including, a glass sheet, an enamel coating on at least a part of a first surface of the glass sheet, a multilayer coating on at least a part of a first surface of the glass sheet and at least partially on top of the enamel coating, such that the enamel coating either comprises no Bi.sub.4Si.sub.3O.sub.12, or, if it comprises Bi.sub.4Si.sub.3O.sub.12, the enamel coating exhibits a crystallinity ratio <5, as measured by XRD, where the crystallinity ratio is the ratio of Bi.sub.4Si.sub.3O.sub.12/Cr.sub.2CuO.sub.4.
