119
.~.~ Utilizing capillary tube or bore means
DEFINITION
Classification: 337/119
(under subclass 114) Subject matter including significant details of a capillary tube or bore at least partially filled by a vaporizable liquid conductor the bore being of such caliber that the liquid is either caused to vaporize at a predetermined current value or to shift its position within the bore thereby disconnecting the contacts of the device. Generally the devices act in a similar manner to a conventional fuse, acting to open a circuit between contacts upon the vaporization of the liquid.
