  • Patent number: 11059959
    Abstract: A tire includes a radio frequency identification (RFID) system and a rubber patch including a topping rubber topping the RFID system, wherein the topping rubber includes a raw material rubber and a reinforcing filler including a boron nitride. In the tire including a RFID system, since the RFID system is covered with a rubber similar to a nearby rubber, generation of a boundary therebetween is suppressed to lower a possibility of the occurrence of initial cracking at a portion where the RFID system is applied, thus increasing durability and safety, and since insulating properties of the rubber covering the RFID system are enhanced, a recognition distance of the RFID system is increased to further facilitate management of distribution and history.

  • Patent number: 8969472
    Abstract: The present invention is directed to ready to use (wet) and setting (dry) repair products with antistatic additives having reduced persistent airborne dust particulates upon sanding thereof. Such wet and dry repair products include, in part, an antistatic additive(s) that can reduce or eliminate the static charge that forms in dust particulates when dried repair products, such as spackling compounds, cementitious materials, and joint compounds, are sanded, for example. In turn, this can help reduce the quantity of airborne dust particulates, the time in which they are suspended, and the distance they travel in a given room or job site. In one example, a repair product for use as a dry repair compound can include an anti-static additive, which can include a cationic charge, and optionally a metal complex. In another example, the repair product further includes water to define a wet or ready to use repair product.

  • Publication number: 20140057048
    Abstract: Ionic liquid (IL)-mediated sol-gel hybrid organic-inorganic materials present enormous potential for effective use in analytical microextraction. One obstacle to materializing this prospect arises from high viscosity of ILs significantly slowing down sol-gel reactions. A method was developed which provides phosphonium-based, pyridinium-based, and imidazolium-based IL-mediated advanced sol-gel organic-inorganic hybrid materials for capillary microextraction. Scanning electron microscopy results demonstrate that ILs can serve as porogenic agents in sol-gel reactions. IL-mediated sol-gel coatings prepared with silanol-terminated polymers provided up to 28 times higher extractions compared to analogous sol-gel coatings prepared without any IL in the sol solution.

    Abstract: An abrasive that can impart a mirror finish, glossiness, or the like to a surface of a workpiece by blasting is provided. A crosslinked polyrotaxane compound having a network structure where crosslinking points are circular molecules of polyrotaxane and also having abrasive grains dispersedly mixed therein is obtained by causing chemical bonding between the circular molecules of the polyrotaxane in a state where the abrasive grains and the polyrotaxane are mixed. Then, the crosslinked polyrotaxane compound is granulated to a predetermined grain diameter to obtain a gel-like abrasive where a part of the dispersedly mixed abrasive grain is exposed at the surface. By using the thus-obtained gel-like abrasive in blasting by projecting the abrasive at an angle tilted with respect to a surface of a workpiece, mirror finishing or the like is possible without making the surface of the workpiece pearskin-like.

  • Patent number: 6077885
    Abstract: The invention provides chromate-free coating mixtures, and coatings formed from these mixtures, that protect an underlying aluminum or aluminum alloy substrate from corrosion. The coating mixtures include a continuous phase selected from organic polymeric compositions, or sol-gels, and a distributed phase, dispersed or dissolved throughout the continuous phase. The distributed phase includes the corrosion-inhibiting chromate-free salts. In accordance with the invention, the mixture of salts includes (1) a first salt selected from (a) the esters of rare earth metals, such as cerium and lanthanum oxalates and acetates, and (b) the vanadate salts of alkali and alkali earth metals, such as sodium metavanadate and calcium metavanadate; and (2) a second salt that is a borate salt of alkali earth metals, such as barium metaborate. In certain embodiments, the coatings of the invention include both (a), and (b), in conjunction with the borate salt (2).
