Abstract: The present invention is directed to a transformer having a stacked core, which includes top and bottom yokes and first and second outer legs. The core also includes an inner leg that is formed from a pair of stacked plates, which abut each along a seam that extends in the longitudinal direction of the inner leg. Each of the upper and lower yokes may be formed from a single stack of plates, or a plurality of stacks of plates. Each of the inner and outer legs may also be formed from a single stack of plates, or a plurality of stacks of plates. The cross-section of the core may be rectangular or cruciform.

Abstract: The invention contemplates a technique for providing loop control on a faulted overhead or underground loop system, while preventing restored current from being fed or back fed into the fault. In particular, the invention provides a method, device, and system for restoring power to a faulted loop distribution system. The inventive method includes detecting a fault on the loop distribution system, interrupting current on the faulted part of the loop distribution system, isolating the faulted part of the loop distribution system from an unfaulted part of the loop distribution system, restoring current to the unfaulted part of the loop distribution system, and preventing the current from flowing to the faulted part of the loop distribution system. The method may further include providing the current to a load.

Abstract: The present invention is directed to a system for modifying a circuit breaker for removable installation in a cell of switchgear system, wherein the unmodified circuit breaker is not adapted for mounting in the cell. The system includes an adapter frame to which the circuit breaker is mounted and gear assemblies mounted to opposing sides of the circuit breaker. The gear assemblies adapt a racking device of the circuit breaker so as to be operable to rack the circuit breaker within the cell of the switchgear system.
Abstract: The present invention is directed to a system and method for monitoring the performance of a heat exchanger. In accordance with the system and method, baseline values of a performance factor (E) for baseline sets of heat exchanger operating values are calculated and stored. A current value of E is calculated for a current set of the operating values and is compared to a retrieved baseline value of E for a baseline set of the operating values that at least substantially matches the current set of the operating values. E provides a measure of the performance of the heat exchanger and is calculated using differential temperatures across the heat exchanger and without using any information concerning the physical construction of the heat exchanger.
Abstract: An electromagnetic actuator is provided that comprises a housing, a solenoid coil, and an armature. The armature is movably disposed in an interior cavity defined by the housing. Irregular gaps are formed between the armature and the housing to increase the initial force of the actuator and to improve the latching force of the actuator after the actuator has been actuated.

Abstract: A fuel cell is placed in parallel with a battery via a mechanical switch. The voltage is held nearly constant by the battery and the power flow is controlled by adjusting the fuel cell operating parameters (such as temperature or air flow) and by opening and closing the mechanical switch. The result is a system that operates at nearly constant voltage without the need for an expensive power conditioning system. The output of the system can then be processed via a traditional power conditioning system such as an inverter or dc-to-dc converter without the need for a wide range of input operating voltages. This reduces the cost and size of the fuel cell power conditioning system.
Abstract: A system and methods that enable a restoration scheme for power distribution systems that is independent of power distribution system component configuration, the number of power distribution system components, and component settings are provided. In a power distribution system, a number of intelligent reclosers having restoration control modules are deployed that execute a restoration scheme. The intelligent reclosers constantly poll cooperating power distribution lines to determine changes in current or voltage provided by the power distribution lines. In the event of a power distribution system fault, the reclosers act in accordance to a predefined restoration scheme to reanimate the unaffected portions of the failing power distribution system.

The in-mold coating composition is curable at a temperature below 300° F. and includes a polymerizable resin, a promoted peroxide that includes a tertiary organic perester, a polymer-bound catalyst that includes a transition metal physically bound to a polymeric composition, and an amine synergist that includes at least one aromatic tertiary amine.
Abstract: Apparatus and method for mixing a fluid dispersion disposed in a container having either a cylindrical or a square shape. The apparatus includes a holding structure having a retaining structure connected to a base. The retaining structure prevents lateral movement of the container both when the container has a cylindrical shape and when the container has a generally square shape with a width substantially equal to the diameter of the cylindrical shape. The apparatus rotates the container about at least one axis.
