Class Information
Number: 318/489
Name: Electricity: motive power systems > Automatic and/or with time-delay means (e.g., automatic starting and/or stopping) > Responsive to direction, inclination or angular position of bodies
Description: Subject matter in which the sensing means are responsive to direction, grade, inclination, angular position, or to a deviation or change from a predetermined value thereof. The systems included herein are "open-loop" controls and thus are not servomechanisms.
