DEFINITION

Classification: 226/11

(under subclass 10) Device wherein the detector is caused to be in a first state by reason of the material being in the device, and is caused to be in a second state by reason of the material not being in the device, and is responsive to a change of state, from first to second, caused by rupture or exhaustion of the material.

(1) Note. Usually, the feed mechanism is prevented from being operated by the regulating means.

(2) Note. See Lines With Other Classes and Within This Class, Relationship to Classes Which Include Subcombinations Utilizable in Advancing Indeterminate Length* Material, for the locus of similar apparatus in other classes.
