Title: Rotary drive for advertising panels - uses stored energy in twisted wire for one direction of rotation and motor for other direction
Inventor: MEUB WALTER
IPC: G09F19/02
Filed: 1978-09-11
Abstract: An electric motor drive is designed to allow a hanging advertising panel to rotate a number of times in alternate directions.
