20090218385	WIRE BONDER - A wire bonder comprises a bonding head with a rocker which is arranged on the bonding head and is rotatable about a horizontal axis. The rocker comprises at least three bores into which a piezoelectric element each is inserted, which element is used either as a sensor or as a piezoelectric drive in order to move a horn which is fastened to a body relative to the rocker. The body is tightly screwed onto the rocker by means of at least three screws, with at least two screws being tightly screwed in a resilient way. The body is pressed against the piezoelectric elements. A membrane is preferably arranged between the rocker and the body, which membrane prevents that shearing forces can act upon the piezoelectric elements.	09-03-2009

20100272883	METHODS FOR VOC-REDUCED PRETREATMENT OF SUBSTRATES AND DETECTION BY LUMINESCENCE - The present invention comprises methods for the pretreatment of substrates, including without limitation, metal or glass surfaces, with activators of reduced VOC content. Preferred embodiments of the invention comprise activators containing methyl acetate as a solvent, at least one adhesion promoter, and a luminescent agent responsive to light of specific wavelengths. In some embodiments, without limitation, an activator composition of reduced VOC content and also comprising a luminescent agent is applied to a substrate before application of additional adhesives or paints, and the substrate is examined under a controlled light source as required to excite the luminescent agent. The luminescent agent in the activator composition appears distinctly where the activator has been applied to the surface, allowing one to detect whether the activator has been properly applied.	10-28-2010
