Abstract: Resilient battery separator media, especially adapted for use as battery separators for starved electrolyte batteries, are formed from air laid, fibrous mats of randomly oriented, entangled microfibers which may be needled to further entangle the fibers. The fibrous mats may be essentially uniform in density throughout their thickness or may include one or two relatively high density, high tensile strength fibrous surface layer(s) and a relatively low density, more resilient fibrous layer integral with and, in one embodiment, intermediate the two surface layers wherein the fibers in the surface layer(s) of the mats are more entangled than the fibers in the resilient layer. The fibrous mats, with one or two surface layers, are formed from the air laid fibrous mats by further entangling the fibers at and adjacent one or both surfaces of the mats, e.g. through hydroentanglement, relative to the entanglement of the fibers in the resilient fibrous layer.

Abstract: Glass compositions displaying decreased far infrared radiation transmission, high biosolubility, and excellent moisture resistance are capable of fiberization by the rotary process, and may be used to prepare thermal insulation products exhibiting high thermal insulation efficiency as reflected by low thermal index values. The insulation products also exhibit excellent stiffness and recovery properties.

Abstract: A fibrous work piece, e.g. a glass fiber mat or blanket, is simultaneously cut, sealed and encapsulated using a focused, high energy liquid jet containing a sealant. The sealant in the focused, high energy liquid jet is deposited on and seals the edges of the kerf formed by the cutting operation to encapsulate dust and short length fibers formed by the cutting of the fibrous work piece. The focused, high energy liquid jet is emitted from a nozzle and the sealant is introduced into and mixed with the liquid before the liquid exits the nozzle. Portions of the fibrous work piece can be compressed by hold down shoes or by one or more high pressure air streams directed onto the work piece adjacent where the work piece is being cut to facilitate the formation of a cleaner edge on the kerf being cut in the fibrous work piece.

Abstract: A fibrous insulation blanket is pre-cut for custom fitting the insulation blanket into structural framework building cavities of different widths. The width of the blanket is substantially equal to the width of a standard cavity to be insulated by the blanket and the blanket has one or more longitudinally extending cuts in a first major surface of the blanket. The cut(s) have a depth greater than one half of the thickness of the blanket and less than the thickness of the blanket whereby the blanket can be handled as a unit for insulating a cavity having a standard cavity width or easily torn apart at a cut by hand for insulating a cavity having less than a standard cavity width. The second major surface of the blanket may have a facing bonded thereto with one or more perforated lines in the facing aligned with the cut(s) to facilitate tearing apart the blanket by hand if required.

Abstract: A new type of multi-chopper for cutting strands or ribbon shaped material such as strands of glass fibers, and a method of using this chopper, is disclosed. The chopper has at least two chopper assemblies on a rotating frame. When one chopper assembly needs repair, the frame is rotated which brings a rebuilt or repaired chopper assembly into operating position quickly and also brings the assembly needing repair into a position where it can be worked on while the other chopper is operating resulting in much reduced downtime. The frame of the chopper can rotate around a vertical or horizontal line, or around a line passing through two opposite corners of a frame.

Abstract: A resilient battery separator, especially suited for use in a starved electrolyte battery, is made of an air laid fibrous mat of randomly oriented, entangled microfibers having a mean diameter between 0.5 and 2.0 microns. The air laid mat weighs between 50 and 450 g/m.sup.2 and has a thickness between 0.01 and 0.5 inches. The fibrous mat may be essentially uniform in density throughout its thickness or may include one or two relatively high density, high tensile strength fibrous surface layer(s) and a relatively low density, more resilient fibrous layer integral with and, in one embodiment, intermediate the two surface layers. The microfibers in the surface layer(s) are more entangled than the microfibers in the resilient layer. In a starved electrolyte battery, the separator has a thickness, when subjected to a loading of 1.5 psi, that is equal to or greater than the spacing between the electrode plates of the battery and, preferably, at least 110% of the spacing between the electrode plates of the battery.

Abstract: A composite filter media includes a fibrous filtration layer of randomly oriented fibers and one or more pleatable stiffening layers which enable the composite filter media to be pleated and hold or retain its pleats. The pleatable stiffening layer(s) may enhance the dirt holding capacity of the composite filter media especially when positioned upstream of the fibrous filtration layer. The composite filter media may also include a flexible covering layer which functions to block the loss of fibers from the fibrous filtration layer. Preferably, the mean fiber diameter of the fibers in fibrous filtration layer increases and the density of the fibrous filtration layer decreases throughout the thickness of the fibrous filtration layer from one major surface to the other major surface of the fibrous filtration layer.

Abstract: A movable retaining wall is used in a first position in a compression baler to retain a compressed mass, such as microfibers, and is then moved to a second position into an opening in a wall of a packaging chamber filling the opening such that a gap between the edges of the interior surface of the retaining wall and the edges of the opening is too small to allow the compressed material to enter the gap when it passes through the packaging chamber and past the gap. To accomplish this requires the use of hidden hinges to guide the retaining wall as it moves from the first position to the second position and back to the first position. The hidden hinges allow the retaining wall to move essentially straight out of the opening in the wall of the packaging chamber before it begins to pivot towards the second position, thus allowing the tight fit.
