During the '70s energy crisis Sylvania came up with the idea of using a current limiting capacitor in a slightly short 48" fluorescent. The cap and a small transformer were housed in a plastic shell. The two halves were assembled with an ultrasonic welder. Ultrasonic my aching ass. Later my dentist had a ultrasonic device for removing calculus from teeth. Besides the whine there was enough cooling water to drown you. Their use was discontinued several years back. When I asked her about it she said everybody, patients and techs, hated the things. Back to the traditional scraping with assorted torture instruments. The ranch supply used to have a jar full of assorted dental instruments for $1 apiece so I have a collection. They certainly are handy for removing fork seals or getting the crud out of firearm nook and crannies.
