Abstract: A patch comprising a lower layer of felt material, and an inner area stitched to the felt and having a desired shape. A first stitched border surrounds the central area, and a second stitched border surrounds the first border.

Abstract: In one embodiment, a method for forming a dry lamination for a composite fiber material structure, for example a wind turbine blade, includes cutting at least two plies of composite fiber material according to a predetermined pattern, arranging the at least two cut plies of composite fiber material in a predetermined arrangement relative to each other, stitching the at least two cut plies together using a thread to secure the at least two cut plies in the predetermined arrangement to form the dry lamination, and spooling the dry lamination into a single roll. The dry lamination can then be transported without misaligning the plies and placed into a resin infusion tool without requiring manual placement of individual plies of composite fiber material.

Abstract: An applique such as a lace-trimming is grafted onto a region of a textile product, such as a towel or a pair of blue-jeans. Previously, said region is marked by lockstitching on the product base material by means of an embroidering machine and removed therefrom, preferably by cutting or punching in a press. The applique is then bridged onto the removed portion of the base material with only a small overlap thereover and joined thereto by embroidering a seam all the way round the overlap with the machine. The seam is preferably about 4 mm wide and the overlap between 2 mm and 3 mm. A method is disclosed wherein the product is permanently retained in a hoop between the marking and joining steps, through the removing step, thus enabling the product to be uniquely placed relative to the embroidering machine before and after temporary removal to the press.

Abstract: A multi-layer article of manufacture includes an intermediate layer of a water-swellable colloidal clay, such as bentonite, sandwiched between two layers of flexible sheet or fabric material wherein the two flexible layers of sheet or fabric material are structurally interconnected through the intermediate clay layer, such as by quilting, with threads, fibers, filaments or strands of flexible material at spaced locations over essentially the entire outer surface areas of both sheet or fabric material layers.

Abstract: A covering layer of leather, textile or plastic sheet material is indirectly attached to a supporting structure, such as a seat or a dashboard, by a band-like insert which is affixed to the covering layer by one or more rows of decorative stitches and is secured to the supporting structure by a pair of rod-like securing elements and a thread, or by one or more pairs of complementary male and female detent elements.

Abstract: Tarpaulins (sometimes termed "tarps") are used to protect an underlying structure or material from wind, rain and the other effects of the weather. Some tarpaulins are insulating in nature. Such insulating tarpaulins in the past have comprised weatherproof membranes with a plastic foam or polyester fiberfill portion between the membranes. These prior membranes have been characterized by short useful life and marginal insulating and weatherproofing ability, either because of limitations of the insulating fill (foam or fiber) or difficulty in sealing the seams or edges between adjacent tarpaulins. The disclosed tarpaulin comprises a first and second membrane sandwiching an insulating batt of a highly resilient fibrous glass insulation. The tarpaulin includes a seam structure around all four edges of the tarpaulin which not only fastens the first and second membranes together but holds the highly resilient fibrous insulating batt in position.

Abstract: A secondary pattern 40 having a mirror image relationship to an applique design of a primary pattern is produced and adhered to the underside 20b of a background fabric 20. Crudely cut segments 42 of fabric material are positioned on the upperside 20a of the background fabric 20 and sewed thereto with a thread of contrasting color in accordance with the secondary pattern 40 on the underside of the background fabric 20. The stitches 44 produced with the contrasting thread are used as precision guides for trimming excess portions of the fabric segments 42 so that each piece assumes its desired shape in accordance with the primary pattern. The stitches 44 produced by sewing with the contrasting thread are also used as precision guides for final applique stitching 50 with a further thread to secure each design component fabric piece (22, 24, 26, 28) to the background fabric and, where desirable, to conceal stitches 44 made with the contrasting thread.

Abstract: The invention relates to a pad for concrete intended to appreciably reduce the setting time of concrete. This pad comprises an essentially water an air tight flexible cover enclosing a heat insulating cushion resting directly over a lower part intended to be laid in contact with the surface of concrete. This lower part is made up of ribbons woven together in the form of a network in such a manner as to have a good mechanical resistance to wear by friction and so as to create a zone between the heat insulating cushion and the surface of the concrete capable of allowing the excess water oozing through the concrete surface to flow only slowly away, thereby avoiding the need of water from an outside source, allowing also the heat resulting from the setting reaction of concrete to accumulate inside the interstices of said network thus to accelerate the setting of the concrete. This pad is particularly useful and efficient during the year's period of cold weather where the setting of concrete is particularly long.

Abstract: Individual plies of woven cloth having different fiber orientation patterns are prelocated with respect to each other and by continuous means, such plies are arranged into a stacked package and sewn together to secure the plies in a predetermined position with respect to each other.

Abstract: Disclosed is a fabrication technique for, and the structure of, a flexible self-sealing fuel tank having a preactivated sealant constructed by laying-up over an innerliner, positioned on a form, prefabricated panels having a self-sealant member stitched into a rubber-coated outer wrap.

Abstract: A cover for a luggage case, embodying decorative side panels of simulated multi-laminar construction. Portions of the periphery of the principal sheet of covering material are cut away and decorative strips fastened in overlying outwardly projecting relation to the cutaway portions to complete the outer contour of the principal sheet. The edge of a surrounding strip is attached, as by stitching, to the outer peripheral edge of the combined principal sheet and decorative strips. After securing the overlapping ends by stitching together, the surrounding strip is readily disposed at a right angle for attachment to the shell of the luggage case.

Abstract: A method of joining together a sheet or sheets of an organic polymer which is not normally melt-processable, e.g. polytetrafluoroethylene, the method comprising the steps of(a) contacting a strip of melt-processable organic polymer, e.g. fluorinated ethylene/propylene copolymer, with the faces of the sheet or sheets in the region of juxtaposed edges of the sheet or sheets,(b) stitching the strip to the sheet or sheets by means of a thread, and(c) heating the strip in order to fuse the strip and/or the thread to seal the holes created by the stitching step, and, where the strip has not previously been fused to the faces of the sheet or sheets, in order to fuse the strip to the faces of the sheet or sheets.Preferably, the thread is of a melt-processable fluorine-containing polymer and a gauze is placed in contact with and stitched to the faces of the sheets opposite from the faces contacted with the strip of melt-processable organic polymer.
