Abstract: An assembly for securing and sealing a dispenser to a flanged container is provided. The assembly includes a sealing collet formed from a resilient deformable molded polymeric material. The sealing collet has an outer surface having an outer diameter, and also has a continuous downwardly extending skirt having a bottom portion thereof extending radially outwardly. The assembly also includes a retaining collar formed from a substantially rigid material, which has a sleeve about its periphery having an inner surface with a diameter sized to encase the skirt of the sealing collet. The retaining collar is slideable through a path of movement over the sealing collet to an assembled position. The sleeve deforms the bottom portion of the skirt radially inwardly to a position under the flange as the retaining collar is slid to the assembled position in order to maintain the sealing collet and the retaining collar in the assembled position and to maintain the seal between the sealing collet and the flange.

Abstract: A multi-pole circuit breaker assembly for interrupting AC power to a load upon the detection of an earth leakage fault or an overcurrent condition includes a pair of circuit breaker units mounted adjacent to an earth leakage module. The earth leakage module includes an electronic circuit that senses a current imbalance between the power line lead and the neutral line lead using a differential transformer. In response to a current imbalance greater than a predetermined value, the electronic circuit periodically energizes a switching circuit that provides power across a solenoid. The solenoid, when actuated, engages a common trip mechanism to open concurrently the contacts of the circuit breakers units. The common trip mechanism includes an elongated bar that extends through the casing of the earth leakage module and the circuit breaker units. The elongated bar engages a U-shaped trip member pivotally disposed in each circuit breaker.
