  • Patent number: 7531569
    Abstract: A method and apparatus for preventing board warpage during the application and curing or drying of liquid epoxies, or the like, on printed circuit boards using a clamping fixture assembly, which includes at least one clamping fixture support and at least one clamping fixture overlay. If desired, a plurality of printed circuit boards may be processed using an appropriate clamping fixture assembly. Furthermore, the clamping fixture may be constructed so a slight bow or curvature thereof can counter either a convex or concave bow or curvature of the printed circuit board. In the method, at least one printed circuit board is mounted to a clamping fixture support whereby a clamping fixture overlay is placed on top of the first printed circuit board.

  • Publication number: 20050101654
    Abstract: An improved process for the preparation of N-amino nitrogen heterocyclic compounds is disclosed and claimed. In an embodiment of this invention, a compound of the formula (VI) is prepared starting from the corresponding indole derivative by way of N-amination and subsequently forming an hydrazone by the reaction with a keto compound in a single step. Further reduction of the hydrazone and subsequent coupling with a pyridine compound affords the compound of formula VI or a suitable salt thereof.
