Abstract: A decorative surface for the exposed welt of a footlet-type sock is formed by knitting a plurality of successive courses of an elastic yarn and a synthetic or natural yarn in plated relationship. Each of the courses includes stitches formed and cast off in selected wales thereof separated by at least two successive float stitches, whereby the combination of the elastic yarn and the aforementioned knitting technique cause relatively wide bands or walewise ribs of raised or high relief fabric separated by relatively narrow bands of base fabric which exhibits a low relief area.

Abstract: The exposed welt of a footlet-type sock is divided by knit construction into a rear portion and a front portion. The rear portion, which is substantially the rear half, is of a substantially freely and outwardly rolled construction. The rolled rear portion is not tacked down and encircles the lower ankle area when emplaced on the foot. The remainder or front portion includes an upper edge which is tacked down in a controlled folded construction. The rear portion is thus left free to roll upon itself into a relatively heavy, thick mass of material. The front portion, on the other hand is folded across the instep of the wearer minimizing the thickness of material beneath the shoe tongue. The rear half is a knitted fabric formed with a combination of body yarn and elastic yarn. The elastic yarn forms the backing fabric for the body yarn, which itself is formed into terry loops.

Abstract: This invention relates to a modular insulating article for insulating the interior of a high temperature furnace. The article comprises an outer shell-like form made of a ceramic fiber blanket, and interior layers made of ceramic fiber blanket material. The interior layers are disposed in planes which are parallel to the walls of the furnace. The layers are joined to each other and to the outer shell by means of an anchor pin and/or cement. The module is attached to the furnace wall by a mechanical anchor, preferably a "T" shaped stud, or refractory cement. The module has improved insulating value because of the disposition of the blankets and provides for the use of a high heat resistant blanket near the hot face and of lower cost high insulation blankets adjacent to the furnace wall.
