Abstract: A method of manufacturing a free-standing electrode film for an electrode of an energy storage device includes providing a powder mixture of at least one electrode active material and at least one fibrillizable binder and feeding the powder mixture to a mill line including one or more presses. At least one press may include a pair of opposing working rolls and a backing roll associated with each working roll. An apparatus for manufacturing a free-standing electrode film includes a mill line including at least one press having a pair of opposing working rolls and a backing roll associated with each working roll, a barrel of at least one of the backing rolls having a diameter that is at least 1.5 times a diameter of a barrel of the associated working roll, the barrels of the opposing working rolls each having a total indicated runout (TIR) of less than 5 ?m.

Abstract: The zipper with removable slider includes two completely separable tooth rows each having opposite first and second end pins overlapping one another. The slider includes two tooth row passages extending therethrough, with an end pin receptacle overlying the tooth row passages. The tooth row passages accept passage of the two tooth rows therethrough and merge to selectively join or separate the tooth rows to form or separate the zipper chain, depending upon the direction of slider movement. The end pin receptacle accepts the end pins at adjacent ends of the first and second tooth rows, and selectively locks those end pins in place in the slider to secure the slider in position on the zipper assembly and hold the zipper closed. The slider may be completely removed from both tooth rows and the panels to which the tooth rows are attached may be separated, inverted or interchanged as desired.

Abstract: The covering system includes a plurality of cover members having releasable fasteners disposed on the periphery of the cover members for forming a case or cover for a pillow, cushion, or other article, such as a laptop computer. The releasable fastener may be a zipper fastener in which each cover member has a stringer attached about its periphery and a slider that is not permanently attached to a cover member, but which is temporarily locked to the teeth assemblies of two cover members so that the cover members can be zipped to form a case for the article. The two cover members may have different designs, and a single cover member may have different decorative designs on opposite sides to form a reversible cover member. The covering system permits panels to be interchanged or reversed to provide the case with any desired decorative appearance.
