    摘要： An opening assist mechanism is for the cradle assembly of a circuit breaker including a housing enclosing separable contacts, and an operating mechanism for opening and closing the separable contacts. The operating mechanism includes a trip bar and a cradle assembly. The cradle assembly includes a first toggle link, a second toggle link pivotally coupled to the first toggle link by a first pivot, and a cradle member pivotally coupled to the second toggle link by a second pivot. The cradle member includes a third pivot and a latching portion structured to engage the trip bar when the cradle assembly is disposed in a position corresponding to the separable contacts being closed or otherwise closeable. The opening assist mechanism comprises an actuator, such as a kicker pin, disposed on the cradle member and structured to engage and move at least one of the first and second toggle links in response to an actuation of the operating mechanism. In this manner, the opening assist mechanism resists the tendency of the first and second toggle links to jam in an over-center configuration.

    摘要： An assist mechanism is for a handle attachment of a circuit breaker having a housing with an operating member operable among a plurality of positions. The handle attachment includes a casing coupled to the circuit breaker housing and enclosing an actuating assembly which interconnects the circuit breaker operating member with a handle that is operable from the exterior of the casing. The assist mechanism is a wave spring having a first end coupled to the casing, and a second end having a wave bend that divides the second end into three sections having three corresponding tangential vector forces. The tangential vector forces provide a bias to the actuating assembly of the handle attachment that differs depending on the position of the circuit breaker operating member. In this manner, the assist mechanism augments energy generated by movement of the operating member and translates it into a corresponding handle attachment movement.

    摘要： An auxiliary switch actuating mechanism is for a circuit breaker including a housing, separable contacts, an operating mechanism with an operating handle interconnected to the separable contacts by a linkage assembly, and an auxiliary switch having a contact member. The auxiliary switch actuating mechanism includes an actuating lever with first and second ends and a pivot portion engaging the housing proximate the auxiliary switch. A torsion spring biases the actuating lever towards engaging and actuating the contact member of the auxiliary switch. The contact member is actuated when the separable contacts are not tripped open and the linkage assembly is not collapsed. When the circuit breaker trips, the linkage assembly collapses, engaging and pivoting the actuating lever, in order to overcome the bias and disengage and deactivate the contact member.

    摘要： A method of making a molecularly imprinted porous structure makes use of a surfactant analog of the molecule to be imprinted that has the imprint molecule portion serving as the surfactant headgroup. The surfactant analog is allowed to self-assemble in a mixture to create at least one supramolecular structure having exposed imprint groups. The imprinted porous structure is formed by adding reactive monomers to the mixture and allowing the monomers to polymerize, with the supramolecular structure serving as a template. The resulting solid structure has a shape that is complementary to the shape of the supramolecular structure and has cavities that are the mirror image of the imprint group. Similarly, molecularly imprinted particles may be made by using the surfactant to create a water-in-oil microemulsion wherein the imprint groups are exposed to the water phase. When reactive monomers are allowed to polymerize in the water phase to form particles, the surface of the particles have cavities that are the mirror image of the imprint group.

    摘要： An improved remote actuator for use with a circuit breaker includes a handle assembly that can be disposed at the exterior of a cabinet and an actuation assembly that is operatively connected with the handle assembly and with the circuit breaker. The remote actuator includes a spring that is connected with a transfer link of the handle assembly and that biases a handle of the handle assembly to either an ON position or an OFF position. The remote actuator includes a fulcrum member on a bracket of the actuation assembly that at least partially overcomes the bias of the spring to facilitate assembly of the remote actuator.
