DEFINITION

Classification: 100/43

(under the class definition) Apparatus having (1) means to detect a condition or change of condition and to cause, in response to the detected condition or change of condition, a control operation modifying the action of the apparatus, or (2) means which when contacted or moved by the material causes such a control operation.

(1) Note. The condition sensed may be a condition of the material treated, of the treating means, or of the apparatus.

(2) Note. Mere periodic, cyclic or sequential operation, that is, that in which the same series of operations in the material are repeated unchanged, in the absence of adjustment of the machine, under a particular stimulus such as the presence of material or the application of power to the drive shaft is not considered automatic control.

(3) Note. In this subclass, for example, are patents in which a condition is sensed during the operation of a press which conveys material while compressing it and in response to such sensed condition controls the size of an adjustable

choke through which the material is conveyed by the press.

72, Metal Deforming,

6+, for a condition-responsive plastic metal shaping machine.

131, Tobacco,

280+, for apparatus relating to the manufacture of cigars and cigarettes or like tobacco articles and in which there are means responsive to a condition to automatically control the operation of the cigarette or cigar apparatus or a part thereof.

33+, for comminutors with means to sense a condition which means causes operation of a control device.

408, Cutting by Use of Rotating Axially Moving Tool,

8+, for drilling machines having means to feed a tool relative to the work and having a control which initiates a change of speed or direction of tool movement in response to the sensing of a condition, or in response to the distance the tool has traveled from a datum position.
