  • Abrasive polishing method
    Patent number: 4512859
    Abstract: A novel method of polishing a workpiece surface comprises passing over the surface in elastically compressive abrasive contact therewith a mass of discrete, elastically deformable pieces each individually consisting of a matrix of elastomeric material containing finely divided abrasive particles substantially uniformly distributed at least along a surface region of the individual piece.

  • Method for the initiation of chemical reactions by low pressure optical pumping
    Patent number: 4142955
    Abstract: When using CO as the absorbing and lasing species for vibration-vibration energy transfer and subsequent vibration-vibration pumping, CO can be made to dissociate and subsequently form C.sub.2 with isotope separation, or CO may be made to chemically react with N.sub.2 to produce CN with isotope separation.
