  • Random coil ultrasonic seal
    Patent number: 4467935
    Abstract: The seal consists of a hollow stud member which is welded to the enclosure to be secured and a cap member which holds the enclosure cover in place when secured to the stud. The cap member has a body section and a pin element extending from it. The pin element has an end portion that is shaped so as to be permanently secured once it enters a receiving element in the stud member. The cap member further has a random identity element, such as a randomly wound coil mounted in a cavity within the cap body. One end of the identity element is fixed to the cap member body section and the other end is fixed to the pin element end portion; such that the identity of the identity element is altered when the end portion is broken away from the pin element.
