.~> Variable periods or intervals between controlling operations
DEFINITION
Classification: 318/443
(under the class definition) Subject matter in which means are provided for effecting a motor operation two or more times in succession at regular or irregular intervals of time.
(1) Note. This subclass includes those systems of repetitious, periodic, or successive operations of a motor in which once the operation of the motor is initiated, either manually or automatically, the operation will take place a plurality of times by virtue of the inherent law or mode of operation of the control means.
(2) Note. Where the operation is controlled by some condition-sensitive device and the operation is effected each time a predetermined condition exists but where the condition may or may not exist so that as a result the operation may or may not occur or take place, classification is not herein but in some other appropriate subclass. See subclass 445 herein below, and the subclasses listed in the Search Notes thereto.
SEE OR SEARCH THIS CLASS, SUBCLASS:
102, for motor systems having means for successively starting and/or stopping or for periodically or repeatedly starting and/or stopping two or more electric motors.
119, for this subject matter where the motor is a reciprocating or oscillating electric motor which is periodic or repetitious in its operation by virtue of its normal mode of operation (i.e., its working or useful output member periodically stops and reverses). 162, for pattern, template, perforated sheet or other predetermined schedule means which can be operated to give repeated or cyclic motor operation controls.
281, for motor systems having means for periodically reversing a motor.
431, for motor systems having means for repeatedly applying starting impulses to a motor to overcome starting friction.
