  • Patent number: 6059913
    Abstract: A process for the continuous production of transdermal therapeutic patches, wherein a laminate of an auxiliary layer (3) siliconized at least on one side, an active substance-containing, pressure-sensitive adhesive layer (4), and a supporting layer (9) is prepared as a strip-shaped web (1) first, and the active substance-containing sections (4') obtained by punching said layers (3) and (4) across the web direction are intermittently transferred onto a second web (2), the punching procedure taking place in the rest phase between the cycles and the transfer procedure onto the second web (2) being carried out preferably at equal distances by means of a transfer device (11, 12), is characterized by the fact that the supporting layer (9) is stripped from the active substance-containing sections (4') during the transfer first, and that then the sections (3') of the auxiliary layer are removed with the aid of a process layer (5) which has been rendered pressure-sensitive adhesive.

  • Patent number: 6004183
    Abstract: A high performance yo-yo incorporates an axle ball bearing comprising non-metallic inner and outer races mounted on the central axle. A full complement axle bearing including non-metallic inner and outer races with matching grooves for retaining a plurality of balls between the bearing races is disclosed. Applicants have found, unexpectedly, that this type of bearing has highly desirable low friction characteristics that provide a long spin time, yet permit retrieval of the yo-yo upon command by a simple flick of the wrist. The central axle mounted in one of the yo-yo components is removably engageable in a sleeve mounted in the other yo-yo component to provide a yo-yo that is easily and conveniently assembled and disassembled.

  • Patent number: 5970629
    Abstract: An improved footwear closure system and composite liner are provided. The composite liner includes a first component that conforms closely to the upper in the area of the heel, toe and side portions of the upper, and a second, stretchable component that extends across and underneath the area between the split of the upper. The second, stretchable component may form an enlarged fold aligned generally with the centerline of the split of the upper. Both components of the composite liner are preferably constructed from a water-repellant or water-proof, breathable material. The composite liner cooperates with an improved closure system having two complementary strips mounted between the split of the upper and underlying the fasteners. When the closure system is drawn tight, any excess portion of stretchable component is collected between and outside the complementary strips, leaving a smooth surface on the inside of the upper in the area of the split and adjacent the instep.
