The present invention is directed to a process of converting lipstatin to orlistat by catalytic hydrogenation. Further, the auxiliary winding has an admittance that is greater than the admittance of the primary winding thereby yielding an asymmetry in the admittances. The amount or degree of flattening and the radius of the U-bolt are variables which applicant controls to successfully cold bend a high-strength steel flattened rod into a U-bolt.
