Title: Field installable electrical operator for a circuit breaker
Inventor: ETSCHEIDT RONALD J
IPC: H01H3/58
Filed: 1990-01-24
Abstract: ABSTRACT OF THE DISCLOSURE            A field installable motor operator for a circuit breaker includes a bidirectionally controllable motor that is coupled through a torque limited module to a circuit breaker operating mechanism.  The motor is bidirectionally driven by a transistor switching bridge that supplies output current in reversible flow directions through one of the windings of the motor to the input of a rectifier bridge that supplies the other winding with currents that flow in the same direction. The torque limited module includes a centering and spacing ring which precisely confines the clutch elements to provide consistent torque.  The motor is supplied with a current pulse of 250 milliseconds duration that is longer than the time required to fully operate the breaker. The clutch slips when breaker operation is completed and permits the motor to overrun without damage.

Abstract: ABSTRACT    The floating guitar bridge is a common mechanical device attached  to a guitars' strings and body which allows the guitar player to raise or lower the pitch of the guitar strings.  This type of bridge is generally called a floating bridge because it is not stable.  In other words, the floating bridge has a tendency to move while playing the guitar which can cause many problems.  The BRIDGE LOCKER is a guitar bridge locking mechanism which locks floating type mechanical string bending guitar bridges thus disabling the floating bridges' ability to move forwards or backwards, thus making the bridge stable or locked in position. the object of the BRIDGE LOCKER device is to allow the guitar player to lock and un-lock the floating function of the floating guitar bridge without hindering the guitarist's playing style. the novelty of the BRIDGE LOCKER is that it locks the bridge to the body of the guitar.  Prior art relative to this subject matter teaches a guitar having a bridge with locking mechanisms which lock the strings to the bridge or the position of the tremolo arm.
