DEFINITION

Classification: 310/15

(under subclass 10) Subject matter in which the movable element of the dynamoelectric device moves to and fro along a straight line path or along an arcuate path which is so short as to be substantially a straight line.

(1) Note. The term reciprocating, as used in this subclass, is limited to straight line motion or nonstraight line motion which is of such short extent that the interrelationship between the moving elements of the dynamoelectric device is substantially the same as if the motion were only along a straight line path.

SEE OR SEARCH THIS CLASS, SUBCLASS:

12, for straight line motion which is unidirectional and does not produce to-and-fro motion.

36+, for dynamoelectric devices which constrain the elements to oscillate to-and-fro motion and in which the extent of motion is such that some provision must be made for the nonlinear interaction between the relatively moving elements

of the dynamoelectric device.
