Abstract: A radial stabilizer is provided for stabilizing levitation passive bearing elements against lateral displacements. The stabilizer provides a means to introduce anisotropy in the radial stiffness of the stabilizer. The presence of anisotropic stiffness has a strongly stabilizing effect on whirl-type rotor-dynamic instabilities. The stabilizer design also provides a means for continuously monitoring the state of health of the rotor by signaling the onset of changes of balance that would be expected to precede any major failure.

Abstract: A fishing reel configured to forwardly release a fishing line includes a reel unit, a spool rotatably supported by the reel unit, an electric power generator that generates an electric power upon a rotation of the spool, an electric component including a controller, an overvoltage protection circuit, and a bypass circuit. The controller operates using the electric power generated by the electric power generator. The overvoltage protection circuit is electrically connected to the electric power generator and the electric component, the overvoltage protection circuit limits a voltage of the electric power output from the electric power generator to a predetermined magnitude. The bypass circuit supplies the electric power generated by the electric power generator to the electric component by bypassing the overvoltage protection circuit upon a determination that the voltage of the electric power generated by the electric power is less than or equal to a predetermined value.

Abstract: Systems and methods for monitoring temperature distribution in downhole equipment using magnetostrictive probes. In one embodiment, an ESP motor has a stator with a rotor and shaft rotatably positioned within the stator. Magnetostrictive sensors are positioned within the motor. Each magnetostrictive sensor has a transducer, a probe, and electronic circuitry coupled to the transducer. The circuitry generates an initial electrical signal that is conveyed to the transducer. The signal passes through one or more coils in the transducer, generating magnetic fields that induce an acoustic signal in the probe. The acoustic signal propagates through the probe and waves are reflected from reflection points in the probe. The transducer senses the reflected acoustic waves and provides corresponding electrical signals to the circuitry, which determines timing intervals associated with the reflected waves and uses this information to determine temperatures at one or more locations in the probe (hence in the monitored equipment).

Abstract: An audible warning system for a generator system is provided. The generator system includes a surge suppressor and a rectifier assembly. The rectifier assembly rotates along with the rotor of the generator system, and generates airflow. The surge suppressor includes a face portion. The audible warning system includes a mounting plate and an acoustic alarm device. The mounting plate is attached to the rectifier assembly to mount the surge suppressor and the acoustic alarm device. The acoustic alarm device includes an air inlet portion in engagement with a face portion of the surge suppressor. In operation, this arrangement blocks fluid communication of the airflow into the air inlet portion, in an operational state. A failure of the surge suppressor allows the airflow to pass through the air inlet portion to generate an audible alarm for an operator.

Abstract: The present invention features a surge-protected cable for use in the wire leads and wire-wound stators of electrical motors. The cable of the invention is of the "filter line" type. This invention reduces failures in the stator windings of variable frequency drive (VFD) motors by attenuating peak voltages and transient voltage spikes. The "filter line" type of cable insulation prevents "dirty" power from unabated travel along the axis. This invention's type of filter line cable features a core member of one or more strands of conductive material overlaid with a primary insulation layer containing ferrites and/or magnetites; this layer is then further overlaid with a flame-retardant insulation jacket layer made of high-temperature material. Both the primary insulation and the outer jacket layer are cross-linked.
