Abstract: A tape wrap system adapted for protecting metal tubular articles, particularly pipes, from corrosion comprising in order, a primer coating covering the surface of the article, an innerwrap over the primer coating and an outerwrap placed over the innerwrap, the innerwrap comprising a polyolefin layer carrying an adhesive layer on its inner surface and a layer comprising a heat fusible material on its outer surface, or a single layer comprising a blend of a polyolefin and a heat fusible moiety carrying an adhesive layer on its inner surface, the outerwrap comprising an impact-resistant polyolefin layer having a heat fusible layer on both surfaces or the inner surface thereof, or a single layer comprising a blend of an impact resistant polyolefin and a heat fusible material; the tape wrap system fusing the innerwrap and outerwrap together when heated and thereafter cooled to form a uniform, continuous and completely closed protective coating which fully protects the article against corrosion and other external d

Abstract: An apparatus which provides for servo regulation of a yarn furnisher for a circular knitting machine which permits the knitting machine to operate at a higher speed, controls and varies the tension of the yarn supplied to a knitting machine, and provides a two-bagging unit receptacle for the directing and receiving of the knitted products.

Abstract: A foldable walker that includes a single latch operator connected with each of left and right latches for the walker's left and right side frames, the left and right latches functioning to latch the left and right side frames open in the use position. Use of the single operator by only one of the user's hands allows both the left and right latches to unlatch the side frames from their open or use position, thereby allowing both those side frames to pivot closed into a collapsed or storage position against the front frame. In preferred form, the left and right latches also function to latch the left and right side frames closed in the storage position. In that preferred form, use of the single operator again by only one of the user's hands allows both the left and right latches to unlatch the side frames from their storage position, thereby allowing both the left and right side frames to pivot back open into the use position relative to the front frame.

Abstract: Novel breathable disposable diapers of per se known configuration comprising a back sheet having a crotch portion and corner portions or wings adapted for engaging the waist and stomach of the wearer, the corner portions being both air-and liquid-permeable, the crotch portion of the back sheet comprising a a liquid-impermeable sheet material carrying an absorbent pad for receiving and retaining body waste materials with the side edges of the sheet material extending around and over the side edges of the pad, whereby to provide a barrier preventing the waste material from escaping through the back of the diaper or through the side edges of the pad.Preferably, a permeable cover or front sheet, is also provided, the absorbent pad in the crotch portion being sandwiched between the cover and liquid-impermeable sheets.

Abstract: A disposable diaper having a backing sheet having a crotch portion, an absorbent pad having a pair of opposed side edges, and a liquid impervious barrier sheet having side margins extending around the side edges of the pad, such that the barrier sheet provides a barrier preventing waste material from escaping through the back of the diaper or through the side edges of the pad.

Abstract: Disclosed is a compression device and method for applying compressive pressure against a patient's limb in periodic compression cycles, wherein an elongated sleeve having a plurality of inflatable chambers is placed over the foot and a portion of the leg, the chambers being sequentially inflated starting with the foot and then form a distal portion of the leg toward a proximal portion of the leg relative to the heart until all of the chambers are inflated.

Abstract: Novel finger-tearable industrial tapes comprising:(1) a lightweight nonwoven synthetic cloth;(2) a polymeric backing layer from about 3 to about 5 mils thick bonded to one surface of said cloth with additional amounts of said polymeric backing material at least partially filling the voids or interstices within said cloth, at least the free outer surface of said backing layer comprising a polyolefinic material; and (3) a layer of a pressure-sensitive adhesive material at least 1.0 mils thick bonded to the opposed surface of said cloth with a portion of the adhesive material on the inner surface of the adhesive layer laminated to the polymeric material of said backing layer within the interstices of said cloth, thereby forming a unitary laminar structure in which the nonwoven cloth is characterized as being sandwiched between the respective polymeric backing layer and adhesive layer materials.
