  • n. In experimental psychology, the device which secures uniform change of pitch in Stern's tone-variator; in the old pattern of the instrument, the mercury trough; in the new pattern, a metal cam. See tone-variator.
  • n. A device for producing desired variations, usually in power or in speed; specifically, in the practice of motor-drawn trains of vehicles on the highway, each unit of which has its own propelling motor, a device attached to the leading and guiding vehicle, by which the limits of speed in each change-gear of the following vehicles may be reduced between determined limits without a resetting of the change-gear lever on each.
  • n. A joint used in underground electrical mains to allow for the expansion or contraction of the metal with changes of temperature.
