  • Publication number: 20220000528
    Abstract: A modular head compression screw system is disclosed and has a cannulated compression screw component with a modular head. The compression screw component includes a tubular body and penetrating tip having a first and second end, and an exterior thread on the tubular body which extends to the second end of the tubular body or penetrating tip. A second exterior thread is positioned around the diameter of the first end to create a posted compression screw. Further, a modular head is removably secured at the first end via the second exterior thread and configured to engage with a driver to advance the compression screw in to the bone. Each modular head component may have a threaded head component which removably secures to the first end of the tubular body, and a fixation component which acts to engage tendons and/or bones.

  • Patent number: 4964873
    Abstract: A method of laundering fabrics includes treating the fabrics with a fabric softening agent, which may be a cationic or nonionic material, and a drape imparting agent, such as a vinyl acetate/vinyl chloride copolymer, in the form of positively charged water-insoluble thermoplastic particles having a softening point of 25.degree.-200.degree. C., especially above 50.degree. C. When selected fabrics are ironed above this softening temperature, the particles coalesce to form a drape imparting film on the fabric while the remaining non-ironed fabrics exhibit a softening benefit.

  • Patent number: 4950412
    Abstract: A fabric conditioning composition contains a fabric softening agent, which may be a cationic or nonionic material, and a polymeric drape-imparting agent, such as a vinyl acetate/vinyl chloride copolymer, in the form of positively charged thermoplastic particles having a softening point of 25.degree.-200.degree. C., especially above 50.degree. C. When treated fabrics are ironed above this softening temperature, the particles coalesce to form a drape imparting film on the fabric. Non-ironed fabrics exhibit a softening benefit.
