Abstract
Abstract An announcing system in which the time, temperature, and commercial weather message announcements are provided on a single mechanism with one record and the TTA system will operate in any spatial orientation including a horizontal position. A stepping motor is used for a magnetic detent of the recording system and operates to positively position the magnetic sound heat in the center of a magnetic record track. Completely automatic time and temperature services are provided with no daily maintenance or initial time setting to maintain accuracy by utilization of the National Bureau of Standard''s WWV Radio broadcasts.
