Electrically Connecting to Pressure Vessels

Resilient conductive disk eliminates need for holes in vessel walls. Grounding disk made from wire and solder and sandwiched between electrical-component support and pressure-vessel wall. Emplaced in component support, disk squeezed to 66 percent of its thickness. Disk conforms to surfaces of support and vessel wall when support attached to wall with adhesive. Disk thus forms reliable electrical contact from support (and its electrical component) to wall.
