Abstract: In methods of preparing asphalt and elastomeric polymer compositions crosslinked with phenol aldehyde resins and sulfur, such as polymer modified asphalt (PMA), it has been discovered that the MP1 compatibility may be improved by adding certain ionic metal salts. Suitable ionic metal salts include, but are not necessarily limited to, zinc oxide, cadmium oxide, and the like. Acceptable elastomeric polymers include, but are not necessarily limited to, styrene-butadiene copolymers. Additional sulfur-containing crosslinkers may also be used.

Abstract: A canalicular implant for insertion through the punctum of the eye and the method of manufacture. The implant is fabricated by cutting suture-like material, such as catgut, of the appropriate diameter to the desired length. The ends of the implant are rounded and polished after cutting by abrasive polishing to remove any sharp edges and burrs formed by the cutting process. This produces an implant with various degrees of rounding at the ends depending on the duration and type of abrasive polishing used. The method of abrasive polishing may comprise tumble polishing, vibratory polishing, or other methods of agitation utilizing dry or wet media comprised of beads, forms, abrasive powders, or other similar substances or combinations of these media.

Abstract: The module for a fuel cell battery comprises an electrochemically active plate which, on the one hand, consists of an oxide-ion-conducting solid electrolyte and, on the other hand, two electrode layers applied to both sides of the electrolyte layer. At least one of the electrode layers is electrically conductively and nondetachably connected to a supporting and electron conduction structure via a plurality of regularly disposed contact elements.
