Abstract: An electric circuit breaker containing electromagnetic-assist means for opposing the contact-repulsion forces developed when a high current flows through the breaker. The electromagneticassist means comprises a rigid support member which when restrained in a fixed position renders the assist means capable of transmitting closing force to the movable contact but which, when released, disable the assist means. Releasable latching means restrains the support member in said fixed position when the contacts are engaged. This latching means is controlled by the motion of a contact-operating member that is coupled to the movable contact through a suitable wipe mechanism.

Abstract: A ring latch for releasably restraining a piston in a preselected position within a cylinder employs about the piston periphery a split ring that is maintained in an expanded latching condition by a key which fits between the ends of the split ring. Latch release is effected by withdrawing the key from its position between the ends of the split ring. Between said ends and the key, rollers are provided that are capable of rolling with respect to said ends in response to withdrawal of the key and of resetting each time the key is withdrawn.
