Abstract: A cutting apparatus and method wherein a blade holder includes two blades which are each designed for cutting web material (e.g., dry film photoresist) in a reverse manner prior to application of the material to a substrate (e.g., dielectric-conductor structure) designed for eventual usage as a printed circuit board or as part thereof (e.g., if laminated up with other, similarly formed substrate members).

Abstract: Back-to back hydraulically linked pistons are mechanically coupled to contact probes and measurement sensors. The pistons are hydraulically linked by small diameter flexible conduits which enable the contact probes and the measurement sensors to be mounted and moved independently of each other without affecting the ability of the measurement instrument to simultaneously measure a plurality of points on a selected predefined surface, such as a human tooth. The present invention overcomes the problems associated with the complex mechanical linkages heretofore required in such instruments.
