摘要： A heat exchanger and electromagnetic pump assembly is disclosed as comprising a heat exchanger including a housing for defining an annularly shaped cavity and supporting therein a plurality of tubes. An electromagnetic pump is disposed beneath the heat exchanger and is comprised of a plurality of flow couplers disposed in a circular array. Each flow coupler is comprised of a pump duct for receiving primary liquid metal, and a generator duct for receiving an intermediate liquid metal. A downcomer tube is disposed centrally of the assembly and passes through the annularly shaped cavity and the array of flow couplers to discharge the intermediate fluid into a first plenum chamber. The first plenum chamber is disposed in communication with the generator ducts of all of the flow couplers, thus permitting the intermediate liquid metal to flow upward therethrough. The generator ducts exit their flows of the intermediate liquid metal in common to a second plenum chamber, which is disposed in communication with the annularly shaped cavity to permit the flow of the intermediate liquid metal therethrough, whereby the intermediate liquid metal is heated by the flow of the primary liquid metal through the tubes. A third plenum chamber receives collectively the flows of the primary liquid metals from the tube and for directing the primary liquid metal to the pump ducts of the flow couplers, whereby a force is exerted on the primary liquid metal, pumping it through the pump ducts.

摘要： A molded case circuit breaker having separable main contacts and an operating mechanism utilized to cause the separable main contacts to open and close. A trip unit is provided to actuate the operating mechanism in desirable circumstances. The circuit breaker has external terminals which are connectable with an external load and an external power supply. A collar is used to interconnect the circuit breaker terminals with the load and power supply. The terminal collar in this case is non-symmetrical. The non-symmetrical collar provides two functions: the first function is that the path of electrical continently between adjacent collars is enlarged for higher voltage applications because of the non-symmetrical nature of each collar; secondly, the circuit breaker case has a seat therein which has the same cross-section as the non-symmetrical collar, so that the collar can only be inserted therein in one cross-sectional orientation.

摘要： This concerns a molded case circuit breaker having separable main contacts and an operating mechanism utilized to cause the separable main contacts to open and close. A trip unit is provided to actuate the operating mechanism in desirable circumstances. The aforementioned trip unit has disposed on an outside surface thereof, dials for adjustment of the thermal and magnetic tripping characteristics of the circuit breaker. The face of the trip unit also has a set of hinge regions disposed therein into which a plastic, transparent, hinged cover may be inserted. The top of the trip unit has a convenient ridge around the outside of the dial regions. The cover after insertion is rotated downward on to the face of the dial region and then moved transversely to abut one of the ridges. Both the cover and the surface of the dial region have bridged openings therein through which a single wire may be fed and locked in place with a solder lock at the ends of the wires. Thus the trip unit has a non-removable cover which covers the dial settings but, because the cover is transparent, the dial settings can be viewed.

摘要： This concerns a four pole molded case circuit breaker having separable main contacts and an operating mechanism utilized to cause the separable main contacts to open and close. A trip unit is provided to actuate the operating mechanism in desirable circumstances. The circuit breaker in this case has four-poles, one of which is a neutral pole. The circuit breaker trip unit has rotatable trip bars therein, one of which is associated with the three-line terminals and one of which is associated with the neutral terminal. If the line terminal trip bar is actuated to move because of a fault to overload in one of the line terminals, only the line terminals will open because the neutral trip bar will not be moved. However, if the neutral trip bar is moved because of a predescribed neutral current value in the neutral conductor all of the contacts including the neutral contact will be opened because of the interlocking arrangement between the neutral trip bar and the line trip bar.
