Abstract: The present disclosure relates to a tape that comprises a weft-inserted warp knit fabric, which utilizes a combination stitch to secure the wales of the fabric. The combination stitch comprises a majority of successive chain stitches that are used with a minority of subsequent successive tricot stitches, such that the stitch follows the expression x+y, where x is the number of successive chain stitches and y is the number of subsequent successive tricot stitches. Contemplated x values are in the range of 5 to 15, and contemplated y values are in the range of 1 to 4. Multiple stitch formations can also be used (e.g., following an x+y/m+n/etc. configuration). The resulting weft-inserted warp knit fabric possesses superior dimensional stability and internal geometry, while maintaining the tearability requisite for a hand-tearable tape product.

Abstract: An architecture for dynamically repairing a semiconductor memory, such as a Dynamic Random Access Memory (DRAM), includes circuitry for dynamically storing memory element remapping information. Memory is tested for errors by writing, then reading a plurality of memory blocks, such as rows or columns, in parallel. Memory is dynamically reprogrammed in order to remap unused spare memory elements for failed memory elements when errors are detected. Unused spare memory elements are remapped utilizing a circuit that overrides unblown fuses or antifuses.

Abstract: A voltage generation circuit includes a voltage pump that receives a supply voltage and develops an output voltage responsive to a pump activation signal. A level detection circuit receives a pump-boost signal and is coupled to the voltage pump to receive the output voltage. The level detection circuit operates in a normal mode responsive to the pump-boost signal being inactive to develop the pump activation signal to activate the voltage pump responsive to the output voltage being less than or equal to a first low threshold value. The level detection circuit operates in a demand-controlled mode responsive to the pump-boost signal being active to develop the pump activation signal to activate the voltage pump responsive to the output voltage being less than or equal to a second low threshold value.

Abstract: Roofing membrane comprises reinforcing scrim fabric and a polymeric material, such as EPDM or TPO. The fabric is preferably a polyester tri-directional laid scrim fabric made from continuous yarns, which is held together by an adhesive, such as polyvinyl alcohol (PVOH) or styrene butadiene rubber (SBR), or any other suitable adhesive such as plastisol polyvinyl chloride. The polyester scrim fabric includes a central area and selvage areas on opposing edges thereof. The selvage areas of the fabric include more strands of yam than the central area, to provide additional strength along the sides of the fabric. Further, the continuous yarns that make up the selvage are not cut along the edges, so that the continuous yarns form loops along the edge portions of the selvage areas.

Abstract: A 2-warp knit, weft inserted fabric having the face thereof calendered to produce a fabric when a PVC film is laminated thereto that has a surface roughness of 2.0 microns or below.

Abstract: A composite structure manufactured on a knit stitch machine and including a pair of preformed substrates joined together by a knitted yarn system while being separated by portions of the yarn system. Preferably the yarn is bulked after knitting and defines a plurality of supports between the substrates. The composite is produced by feeding the substrates through a knit stitch machine, on opposite sides of a spacer bar and developing the knit stitches of the yarn system through and about the substrates while located on opposite sides of the spacer bar. After the composite is produced it preferably is subjected to heat to cause yarn of the yarn system to bulk and form supports between the substrates. The composites may be enclosed in sealed polymeric envelopes to form a cushioning pad, or may be used for filtration, insulation or other uses. The process of producing the composite and the spacer bar are also disclosed and claimed.

Abstract: A 3-bar Raschel warp knit fabric for use in grasscatcher bags which has an additional high tenacity yarn knit in to provide a lower elongation yarn in the course direction to prevent the grasscatcher bag from dragging the ground as it is being filled. The fabric also has a second textured needle lap stitch yarn to provide cover and to prevent the exhaust of dust to the atmosphere from the interior of the bag.

Abstract: A method of making a roofing membrane having a reinforcing fabric saturated with a bituminous material. The reinforcing fabric comprises a first fiberglass scrim layer to which is stitched a non-woven polyester mat.

Abstract: A warp knit fabric having loops projecting outwardly therefrom on both the face and back of the fabric which can be used as a wiping cloth, female connector fabric, etc. The fabric is a three-bar fabric having bar movements of (1) 1-0, 0-1, 1-0, 0-1; (2) 6--6, 0-1, 4--4, 0-1; and (3) 4--4, 3--3, 4--4, 1--1.

Abstract: A wallcovering material having a paper backing being color and/or design printed face to which substantially parallel warp and fill yarns are tricot stitched thereto to provide an aesthetic structure through which the color and/or design shows through. The warp and weft yarns are knit to the paper backing material and held firmly in place by the polyethylene film on the face of the paper backing. The warp and weft yarns are openly spaced so that the color and/or design printed on the paper shows through and provides a pleasant view to the area in which the wallcovering is installed.
