摘要： A locomotive diagnostic system. A first sensor outputs a measurement of a first state variable (such as vibration) of a first locomotive component, such as a blower fan bearing set, and a second sensor outputs a measurement of a second state variable (such as rotational speed) of a second locomotive component, such as a blower fan shaft. The first state variable is indicative of the operation of the first component and is dependent on the second state variable. Data represents, for each of a number of different values of the second state variable, first, second, and third ranges of values of the first state variable which indicate, respectively, normal, worn, and failed operation of the first component. A mechanism, such as a digital computer, determines if the measurement of the first state variable is within the first, second, or third range of values of the first state variable for the measurement of the second state variable.

摘要： A self-shielded gradient coil assembly for an MR imaging system has inner and outer gradient coil windings disposed in coaxial relationship and defining a hollow annular space therebetween. Inner and outer helical cooling tubes are affixed to the outer and inner surfaces of the inner and outer gradient coil windings, respectively, by a thermally conductive epoxy, and a concrete filler material substantially fills the remaining hollow annular space. The concrete filler material may be poured into the hollow annular space to fill the space, or a pre-formed hollow concrete cylinder may be inserted coaxially into the space, defining remaining inner and outer annular volumes which are then filled with a thermally conductive epoxy bonding together the inner and outer gradient coil windings, the cooling tubes and the hollow concrete cylinder.

摘要： An electrical transformer includes a housing, a transformer core and winding subassembly located in the housing, and a cooling fan subassembly. The cooling fan subassembly includes a variable speed fan located outside the housing, a temperature sensor located near the housing, and a controller having an output port connected to the variable speed fan and an input port connected to the temperature sensor. The controller reduces the fan speed (and hence the fan noise) when a lower fan speed can maintain the desired temperature as sensed by the temperature sensor. Preferably, the electrical transformer further includes an active mount subassembly and/or (when the housing includes a tank containing transformer fluid) a mechanism for varying the dynamic pressure of such transformer fluid.

摘要： A noise reducing clip device includes a clip body and a fulcrum-defining element. The clip body receives a washing machine wash tub wall and a fastener to secure the tub wall to the clip body and attach the clip body and tub wall therewith to a support leg disposed adjacent to the tub wall. The fulcrum-defining element is formed on and protrudes outwardly from the clip body for spacing the clip body from the support leg and providing only contact of the support leg with the fulcrum-defining element about which contact the support leg may undergo twisting and rocking motion induced by operation of a washing machine motor without imparting such motion to the tub wall via the clip body.

摘要： A method for making a rotor for an electric motor. An elastomeric ring loosely slides over a motor shaft and inside a flux ring. End plates are attached to the longitudinal ends of the flux ring so as to longitudinally compress the elastomeric ring which radially inwardly expands against the motor shaft and radially outwardly expands against the flux ring. In a modification, the flux ring has a smaller-diameter annular disk near each of its longitudinal ends, and each attaching end plate longitudinally compresses a longitudinally-shorter elastomeric ring against a corresponding smaller-diameter annular disk.
