20130015632 | WHEELCHAIR WITH LEVER DRIVETRAIN - A manually powered wheelchair includes a first lever associated with a first rear wheel and demountably coupled to a first drivetrain, the first lever having a first brake thereon. The wheelchair also includes a second lever associated with a second rear wheel and demountably coupled to a second drivetrain, the second lever having a second brake thereon. Each drivetrain includes a chainring, a chain, and a freewheel, and each drivetrain has a fixed gear ratio. The freewheel of each drivetrain is actuated by manual pivoting of the lever associated therewith. In use, the wheelchair achieves changes in mechanical advantage when a user shifts the user's hands up and down the first and second levers. | 01-17-2013 |

20090143527 | Glycerol Ester-Free Functionalized Vegetable Oil Derivatives and Their Latex Compounds - The present invention is directed to a fatty amide (meth)acrylate monomer, methods of making the monomer, and latex polymers comprising the fatty amide (meth)acrylate monomer. The monomers are derived by reacting unsaturated vegetable oils with ethanolamine or substituted ethanolamine. The vegetable oil derivative is then reacted with either (meth)acryloyl chloride or (meth)acrylic acid to form a fatty amide (meth)acrylate monomer or the product of the reaction of hydroxyethyl (meth)acrylate reacted with isophorone diisocyanate to form a urethane fatty amide (meth)acrylate monomer. The increased hydrophilicity of the fatty amide (meth)acrylate monomer facilitates the diffusion through the aqueous phase. The monomer synthesis is designed to be glycerol ester-free to increase long term stability for monomers and polymers. | 06-04-2009 |
