  • Publication number: 20050137200
    Abstract: This invention encompasses anthranilamides with heteroarylsulfonyl side chain, process for their preparation, their use as medicament or diagnostic aid, and pharmaceutical preparations containing them. Compounds of formula I, in which R1 to R7 have the meanings stated in the claims, act on the Kv1.5 potassium channel and inhibit a potassium current which is referred to as the ultra-rapidly activating delayed rectifier in the atrium of the human heart. They are therefore suitable as novel antiarrhythmic ingredients, such as for the treatment and prophylaxis of atrial arrhythmias, e.g. atrial fibrillation (AF) or atrial flutter.

  • Publication number: 20050124681
    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.
