| This technology is supported by one U.S. patent: U.S. Patent Classes & Classifications Covered in this Patent: Class 524: Synthetic Resins Or Natural Rubbers -- Part Of The Class 520 Series. Part of the Class 520 Series - some general types of subject matter include: Solid synthetic resins, per se, regardless of utility; processes of preparing a synthetic resin involving a chemical reaction; reactable compositions which form a product; processes of purifying a solid synthetic resin or composition containing a synthetic resin by a chemical or physical process; process of reclaiming or recovering a solid synthetic resin; processes of treating a synthetic resin or specified intermediate condensation product with a reactant, or product thereof; blends of solid synthetic resins, processes of preparing or treating such blends; chemically reacted solid synthetic resins or processes of preparing; potentially reactable compositions which contain a solid synthetic resin or SICP and products of such a reaction, or processes of preparing; room vulcanizable potentially reactive compositions which merely require moisture and which are usually activated by heat and/or pressure to form a product; compositions of a nonreactant material and a solid synthetic resin or SICP; compositions containing a structurally defined material which is dispersed in a matrix which is not identified by overall dimension or some structure or processes of preparing; single-layered products containing a solid synthetic resin or composition thereof reciting no structure or dimension, or a fiber, filament, etc., which is no more than the material from which it is made, nonstructured single-layered web or sheet is encompassed; particles or a powder, per se, of a solid synthetic resin or composition thereof for which particles or powder no dimensions are recited; reactable compositions which form a product proper for this class and contain a photoinitiator or photosensitizer which are activated by wave energy or processes of preparing. Subclass 59: Coal, bituminous additive, extract, or derivative thereof; or oil shale; or fatty still residue DNRM Class 152: Resilient Tires And Wheels (1) spring wheels for land vehicles; (2) resilient tires for land vehicle wheels; (3) patches for pneumatic tires; (4) anti-skid devices for resilient tires; (5) devices for securing tires to wheels, and (6) pneumatic tire inflating devices combined with the vehicle or wheel or remaining with a particular tire between periods of inflation, or designed to fill one tire from another. Subclass 151: TIRES, RESILIENT Subclass 209.1: Tread Class 208: Mineral Oils: Processes And Products Processes for the recovery or treatment of natural occurring mineral oil which result in the production of a purified or modified mineral oil or of coke.
