Abstract: A fabric for use by a papermaking machine, the fabric including a plurality of weft yarns, a plurality of warp yarns, and a woven fabric resulting from a repeating pattern of the weft yarns and warp yarns. Each of the weft yarn in the repeating pattern having a sequence of starting at a starting point then sequentially going over three adjacent warp yarns, under one warp yarn, over one warp yarn, under three warp yarns, over one warp yarn and under one warp yarn, the sequence then repeating.

Abstract: A composite papermaking fabric comprising an upper support fabric and a lower contact fabric. The upper fabric is formed of warp yarns, fabric born warp yarns and weft yarns interwoven to provide the upper fabric with a support surface forming a one up, one down weave. The lower fabric is formed of the fabric born warp yarns interwoven with weft yarns in a weave pattern which provides a weft yarn dominated contact surface. Each of the fabric born warp yarns also weaves over at least one of the upper fabric weft yarns during each repeat of the weave pattern forming binding points which bind the upper and lower fabrics together.

Abstract: A forming fabric is formed by repeat units, being determined by a paper side weave and a wear side weave, the paper side weave having first yarns being interwoven with second yarns extending in cross direction relative to the first yarns. The first yarns passing over one or more consecutive second yarns define over-floats and first yarns passing under one or more consecutive second yarns define under-floats. Each weave repeat unit has at least two like floats having different lengths and forming part of the paper side weave, wherein floats are like floats if all of the floats are either over-floats or under-floats.

Abstract: A watercraft arresting system and method including an entanglement subsystem including at least two arms in a V-configuration. A deployment subsystem deploys the entanglement subsystem so the arms are spread apart in the water in the path of the watercraft to arrest it.

Abstract: The invention relates to a forming fabric, with a paper side fabric having paper side threads and with a wear side fabric having wear side threads. The paper side fabric and the wear side fabric are superimposed to one another and connected by binding threads weaving with both the paper side threads and the wear side threads, both extending in cross direction relative to the binding threads. The binding threads form part of the weave pattern of the paper side fabric and form part of the weave pattern of the wear side fabric, and alternate from weaving with the paper side fabric to weave with the wear side fabric and vice versa, thereby crossing each other forming crossing points.

Abstract: A composite forming fabric (10) comprising a paper side layer (12) having a paper side surface, a machine side layer (14) having a bottom wear side surface, and a plurality of pairs of first and second intrinsic, interchanging weft binder yarns (16, 18, 20, . . . 34) for binding together the paper side layer (12) and the machine side layer (14). At least of said plurality of pairs of first and second intrinsic, interchanging weft binder yarns have at least four segments (S1-S4) in the paper side layer (12) within each repeat of the weave pattern in the fabric, and these segments provide an unbroken weft path in the paper side surface. Each of the first and second intrinsic, interchanging weft binder yarns (16, 18, 20, . . . 34) of each binder pair having at least four segments (S1-S4) in the paper side layer (12) within each repeat of the weave pattern binds to at least one warp yarn (2-20) in the machine side layer (14) vertically underlying one of the segments (S1-S4).

Abstract: A flow through pressure regulator apparatus and method for directing a flow of fuel and reducing noise generation within a fuel system. Present invention includes a lower housing having fuel inlet where fuel flows through the fuel inlet and communicates with a valve biasing member through a fuel chamber. The valve biasing member permits or inhibits fuel flow through the fuel chamber by opening and closing a valve element. The valve biasing member comprises a flat disk having at least two reticulated concentric rings coupled by at least one bridge. As fuel flows past an open valve element, the valve biasing member diffuses the flow of fuel. A fuel cover directs the flow of fuel from the valve biasing member to the fuel outlet.

Abstract: A papermaker's fabric, usable in the forming section of a paper machine, having two layers of cross-machine-direction (CD) yarns. Interwoven with the CD yarns is a system of MD yarns. At least some of the MD yarns are grouped into alternating pairs comprising a crossing pair having a first MD yarn and a second MD yarn and a second pair having a third MD yarn and a fourth MD yarn. The first MD yarn and the second MD yarn combine to weave each CD yarn in the first layer and cross between the first layer and the second layer. The left and right warp yarns in the pairs are aligned in such a way that like adjacent yarns from adjacent pairs have MD cell lengths greater than or less than the MD cell lengths from non-like adjacent yarns from adjacent pairs. The third MD yarn is interwoven with the first layer of CD yarns and the fourth MD yarn is interwoven with the second layer of CD yarns.
