摘要： A current limiting circuit breaker mechanism having two pairs of separable contacts closely spaced for electrodynamic repulsion upon the occurrence of a short circuit overload condition utilizes a pair of arc chute assemblies to cool and extinguish the arc that occurs when the contacts become separated. The arc chute assemblies contain a plurality of arc chute plates supported by side supports. The arc chute plates are aerodynamically designed to facilitate the easy flow of the arc plasma gases into and out of the chute and provide minimal reflection of the arc plasma wave against the contact arm.

摘要： A steam turbine includes a diffuser that has a bearing cone and an inner plate of a steam guide that define a passage through which steam flows. An outer plate is disposed with respect to the inner plate such that an opening is located between the inner and outer plates. At least one hole is located in the inner plate. A water tube is disposed in the opening, the water tube having water flowing therethrough which condenses at least a portion of a flow of steam flowing in the passage thereby creating at least a partial vacuum within the opening. The vacuum creates a suction effect through the at least one hole in the inner plate that can cause at least a portion of the flow of steam in the passage to attach itself to an inner surface of the inner plate.

摘要： A lamp having a lighting source, integral electronics, and a thermal distribution mechanism disposed in a housing. The thermal distribution mechanism may include a variety of insulative, radiative, conductive, and convective heat distribution techniques. For example, the lamp may include a thermal shield between the lighting source and the integral electronics. The lamp also may have a forced convection mechanism, such as an air-moving device, disposed adjacent the integral electronics. A heat pipe, a heat sink, or another conductive heat transfer member also may be disposed in thermal communication with one or more of the integral electronics. For example, the integral electronics may be mounted to a thermally conductive board. The housing itself also may be thermally conductive to conductively spread the heat and convect/radiate the heat away from the lamp.
