DEFINITION

Classification: 72/31.01

WITH INDICATION OF CONDITION OR POSITION OF WORK, PRODUCT, OR MACHINE ELEMENT (E.G., BROKEN TOOL ALARM, ETC.):

(under the class definition) Subject matter comprising a step of, or means for visibly, audibly, or tacitly signaling

information related to a physical state or location of the work, a product, or component of a manufacturing means of this class.

(1) Note. This subclass (31.01) is the locus of patents directed to means for or method of signaling the occurrence of a give condition (e.g., absent or misaligned work, etc.) associated with a device or operation of the class type. The signal is generally of the off or on type; if measurement or counting is involved, the combination should be placed in the subclasses indented hereunder.

(2) Note. The provision of a gauge, mark, or scale on a machine table, against which the work is to be laid for direct measurement, comparison, or placement for an operation of the class type, is not deemed an "indicator" for this subclass; similarly, the step of visual inspection (for length, straightness, etc.) is not deemed detection or indication for this subclass. A patent claiming any of the above-noted features would be placed on the basis of its other claimed subject matter.
