after doing a little more patent digging i found that is a vibration mount and is not the earliest such device the method for ultrasonic welding seems to be first mentioned in in feb raytheon has a patent for a general vibration device from nov which they claim can be used for bonding plastics and other materials by localized heating among other things the first patent to use ultrasonic welding with respect to metals was aeroprojects sonobond in april but they do not seem to be the first to pioneer this process in any other regard i will continue to read up on patent searches and let you know how it goes
