Abstract: A combination drinking container and electronic audio amplification device includes a container for holding a beverage having a sidewall structure with an open top and an open bottom. A base assembly is connected to the container and includes a base holding a speaker isolated from the beverage adjacent the open bottom of the container and retaining a sound generating device and a source of electrical power in communication with the speaker and the sound device. The speaker converts electrical signals from the sound generating device and emits sound waves that are projected through and conducted by the sidewall structure for delivery through the open top of the container.

Abstract: An electrical device, such as a circuit breaker, for interrupting the flow of current, which includes a stationary contact, a blade having a movable contact, a releasably latchable trip lever, a bimetal, and a magnetic armature. The movable contact is movable into and out of engagement with the stationary contact. The trip lever is releasable from a latched position for movement to a tripped position to cause separation of the stationary and movable contacts. The bimetal causes the release of the trip lever from the latched position by having the armature drawn a predetermined distance in response to a predetermined short circuit current. The trip lever is held in the latched positioned by a hardened latch having a minimal surface area, which is positioned near an opening located in the armature. When the predetermined short circuit current flows through the bimetal, the trip lever moves to the tripped position.

Abstract: A reverse deflection prevention arrangement is provided for use in a circuit breaker for preventing a bimetal from bending in a direction opposite its normal thermal deflection. The reverse deflection prevention arrangement includes a tab portion extending from a yoke and a corresponding block member disposed on the inside surface of a circuit breaker cover. The tab portion engages the block member when the bimetal is forced to deflect in the direction opposite its normal deflection. An alternate embodiment of the reverse deflection prevention arrangement includes a reinforcement member secured to one end of the bimetal. The reinforcement member strengthens and supports the bimetal so that it is prevented from bending in the direction opposite its normal thermal deflection.
