Abstract: A heat sink is for an integrally fused low-voltage power air circuit breaker including a line terminal and electrical bus work coupled to a current limiter. The line terminal, electrical bus work, and current limiter contribute to the formation of a thermal dam. The heat sink includes a heat exchanger structured to be coupled to the line terminal at or about the current limiter in order to expel heat from the thermal dam. The heat exchanger comprises at least one conductive member having a first end, a second end, and a plurality of bends therebetween. The heat exchanger includes heat reduction features, such as, for example, two conductive members having a number of air gaps therebetween to facilitate heat convection, a dark coating to expel heat, materials having a high thermal conductivity, and surface-enlarging mechanisms such as fins, flanges and apertures.

Abstract: A molded case circuit breaker is provided with rubber stop assemblies disposed between the contact assemblies adjacent the outside poles and the cover portion of the housing. The rubber stop assemblies are disposed such that they prevent the contact assemblies from damaging the cover. The stop assemblies include a dual purpose U-shaped bracket having two parallel sets of arms. One set of arms is provided with aligned apertures at the free ends for receiving a pin which defines a pivot point for the crossbar assembly. The other set of arms is also provided with aligned apertures at the free end for receiving a metal pin for carrying a cylindrical shock absorber assembly. The shock absorber assembly is mounted adjacent outside poles above the contact carrier but spaced away from the inside of the cover of the circuit breaker. Thus, when the contact arm is opened, it will stop against the shock absorber and not damage the circuit breaker cover.

Abstract: A closure device for a container comprising a closure member adapted to close the opening of a container and through which is provided an opening, smaller than the container opening, which allows the outflow of material from within the container, a lid member adapted to close the opening in the closure member, and a spout extending from a peripheral portion of the closure member which is adapted to controllably conduct away from the container material flowing through the opening in the closure member and out of the container.In another embodiment of the invention a container with a top having a preformed access opening is provided with a spouted closure device. The closure device comprises a closure member through which is provided a similar preformed access opening, a lip which provides fluid-tight contact with the top of the container, and a spout extending from a peripheral portion of the closure member.
