Abstract: Methods and compositions for modulating development and defense responses are provided. Nucleotide sequences encoding defensin proteins are provided. The sequences can be used in expression cassettes for modulating development, developmental pathways, and defense responses. Transformed plants, plant cells, tissues, and seed are also provided.

Abstract: A molded case circuit breaker that includes a double headed calibration screw. The calibration screw has a first and second end with identical convex tip surfaces and screw driver engagement surfaces. The convex tip surface is suitable for engaging a bi-metal thermal overload element. The screw driver engagement surface is suitable for applying a screw driver to adjust the calibration screw position in order to adjust the deflection of the bimetal and calibrate the thermal overload protection. At least one calibration screw planar surface allows for improved sealant injection to permanently fix the screw position and associated calibration setting following adjustment.

Abstract: A latching system for a circuit breaker is arranged to actuate a trip unit and interrupt circuit current upon occurrence of a short circuit or an overcurrent condition. The latching system employs an armature having a recess formed therein and a cradle having a cradle tip arranged to releasably engage the recess. A thermal magnetic trip unit is depicted within the circuit breaker for the purposes of detecting overcurrent conditions through the electric path. During current transport through the circuit breaker, the current is thermally sensed by means of the bimetal and magnetically sensed by means of the magnet. The armature rotates against the return bias of a compression spring to release the cradle tip from the recess and allow counterclockwise rotation of the contact arm. The rotation of the contact arm causes the separation of the movable and fixed contacts under the urgence of a mechanism spring.
