摘要: Disclosed herein is a fibrous tissue sealant in the form of an anhydrous fibrous sheet comprising a first component which is a fibrous polymer containing electrophilic or nucleophilic groups and a second component capable of crosslinking the first component when the sheet is exposed to an aqueous medium, thereby forming a crosslinked hydrogel that is adhesive to biological tissue. The fibrous tissue sealant may be useful as a general tissue adhesive for medical and veterinary applications such as wound closure, supplementing or replacing sutures or staples in internal surgical procedures, tissue repair, and to prevent post-surgical adhesions. The fibrous tissue sealant may be particularly suitable for use as a hemostatic sealant to stanch bleeding from surgical or traumatic wounds.

摘要: A method for heating a composite comprising a nonconductive material that is a thermoplastic or a thermoset reinforced with conductive materials such as carbon fibers, by incorporating coupling particles in the structure. The structure is oriented in the plane of a magnetic field induced at frequencies from 3 kHz to 7 MHz, whereby the coupling particles respond as susceptors to the induced magnetic field and are preferentially heated (carbon fibers are not heated).

摘要: This invention concerns a process for imparting corrosion and creep resistance to a coating prepared from a particulate polymer composition and applied from a fluidized bed or by electrostatic spraying over metal substrates. The process of the present invention provides for maintaining the content of acid functionality of an acid-functionalized semicrystalline or acid-functionalized amorphous particulate polymer of the particulate polymer composition within a desired range. The acid functionality on the particulate polymer can be maintained, by crosslinking and/or neutralizing, within a desired range of the acid content which results in imparting corrosion and creep resistance to the coating applied over the metal substrates. Neutralizing the acid functionality of the polymer component results in hardening the coatings resulting therefrom. The process further provides for adding anticorrosive pigments to the composition for further improving corrosion resistance of the resultant coatings.

摘要: An apparatus for corona discharge treatment of an article, and in particular an article comprising a conductive composite, includes a first electrode, which is a rotating, high-frequency voltage electrode and a second electrode, which is preferably a translation table, disposed with respect to the high-frequency voltage electrode so as to provide a return path to ground. The translation table supports the article to be treated, and oscillates with respect to the first electrode. Since translation table supports the article to be treated, the article itself is grounded, which is important when treating conductive composite articles. An adjustment mechanism provides a constant gap between the high-frequency voltage electrode and the article, so that the voltage does not seek the article. This enhances the efficiency of the corona treatment of the article. The first electrode rotates continuously and independently of the motion of the article in order to dissipate heat from the high-frequency voltage electrode. This arrangement makes the apparatus particularly useful for treating articles comprising conductive fibers, since such articles have relatively high power requirements.
