System for orienting a rotating member
First Claim
Patent Images
1. A system for accurately orienting a member rotated by a motor in a desired orientation, said motor being responsive to a motor speed control means whereby said motor is controlled by said system through said motor speed control means, said system comprising:
- a slow down sensor and a stop sensor located in spaced relation to said member, actuating means arranged on said rotated member for passing in close proximity to said sensors whereby said slow down sensor and said stop sensor sequentially provide slow down and stop signals to a logic control means,said logic control means actuating said motor speed control means in response to said slow down and said stop signals whereby said motor is responsive to said slow down and said sensors; and
motor start control means responsive to said motor speed control means for delaying rotation of said motor for a predetermined time after said system is voltage actuated.

Abstract
A system for orienting a rotating member includes a slow down and a stop sensor. A logic circuit receives inputs from the sensors to slow and stop the rotating member. A slow down signal must be received before a stop signal can effect the rotations. Starting is delayed to enable the motor starting circuit to go through the necessary start up sequences.
