Abstract: A device for reversed operation of a first handle is provided. The first handle is of a circuit breaker. The device includes a housing that is attachable to the circuit breaker, and a lever that is rotatably attached to the housing. The lever includes a body, and an arm and a second handle each extending away from the body. The lever is movable in a first direction relative to the housing in response to a force at the second handle, such that when the housing is attached to the circuit breaker and the lever moves in the first direction relative to the housing, the first arm is configured to press against and move the first handle of the circuit breaker in a second direction relative to the housing, the second direction being away from the first direction.

Abstract: A circuit breaker accessory for reverse handle operation of a circuit breaker installed in a vertically inverse orientation includes a housing configured for attachment to a face of a circuit breaker on which a switching handle of the circuit breaker is arranged. A reverse switching handle is configured with a transverse sleeve for a pivot axis of operation between a down position and an up position with a top to protrude through the housing. An extension arm has a pivoting connector at a first end for coupling with the bottom end of the reverse switching handle, and a collar at a second end for coupling with the switching handle of the circuit breaker. A pivot shaft couples the transverse sleeve of reverse switching handle with the housing, arranged to fit through the transverse sleeve. The reverse switching handle operates in a direction opposite to the switching handle of the circuit breaker due to extension by the extension arm.

Abstract: A molding tool comprises a mold component having a body, a molding surface thereon, and at least one passage internal to the body for conducting a heat transfer fluid from an inlet thereto to an outlet therefrom, the passage comprising a roof spaced from and located proximate the molding surface, a floor spaced from the roof and located farther from the molding surface than the roof, the roof and floor being joined to define a passage cross section, wherein the roof extends within the tooling body so as to substantially conform in size and shape to one or more contours of the molding surface and at least one of the area of the passage cross section and the offset distance of the passage from the molding surface varies between the inlet and outlet. Advantageously, the passage comprises at least one support pillar to constrain deflection of the molding surface during molding.
