摘要： A rotating electric machine in which the armature winding thereof and other parts are supported by a liquid to withstand the mechanical stresses applied during transient overloads and the like. In particular, a narrow gap is provided between the armature winding and the stator which supports it and this gap is filled with an externally pressurized viscous liquid. The liquid is externally pressurized sufficiently to balance the static loads on the armature winding. Transient mechanical loads which deform the armature winding alter the gap dimensions and thereby additionally pressurize the viscous liquid to oppose the armature winding deformation and more nearly uniformly to distribute the resulting mechanical stresses.

摘要： The present invention provides a variable reluctance actuator system and method that can be adapted for simultaneous rotation and translation of a moving element by applying a normal-direction magnetic flux on the moving element. In a beneficial example arrangement, the moving element includes a swing arm that carries a cutting tool at a set radius from an axis of rotation so as to produce a rotary fast tool servo that provides a tool motion in a direction substantially parallel to the surface-normal of a workpiece at the point of contact between the cutting tool and workpiece. An actuator rotates a swing arm such that a cutting tool moves toward and away from a mounted rotating workpiece in a controlled manner in order to machine the workpiece. Position sensors provide rotation and displacement information for a swing arm to a control system. A control system commands and coordinates motion of the fast tool servo with the motion of a spindle, rotating table, cross-feed slide, and in feed slide of a precision lathe.

摘要： The speaker system consists of a single housing containing a tweeter, mid-range and woofer transducer units. The tweeter unit consists of an elongated, aluminum ribbon positioned vertically and connected to the top and bottom of a rigid elongated frame. The ribbon is located between sets of split magnets which are designed to provide a shaped magnetic field that helps center the ribbon in a direction perpendicular to its length. Additional electromagnetic centering is provided by flat ribbon conductors located on the surfaces of the magnets sets which return the current carried by the ribbon. The mid-range transducer is similar to the tweeter transducer in construction except that the edges of the mid-range ribbon are mechanically attached to the frame by foam strips. In addition, the mid-range ribbon is transversely corrugated at variable slant angles relative to ribbon longitudinal axis. The woofer transducer consists of an elongated, trapezoidal, corrugated aluminum ribbon attached to a non-vibrating frame. In order to provide a single electrical path, the ribbon is divided into a serpentine path by a series of cuts. To prevent undesirable auto effects, the ribbon is tensioned in a transverse direction.

摘要： In an induction generator, an additional set of stator windings is provided, separate from and secondary to the main stator windings upon which the generator's output voltage is generated and supplied to the load. This separate stator winding is provided for the purpose of supplying the generator with the reactive electrical power it needs to maintain the rotating stator field and supplying any reactive power needed by the load. Thus, there is no need to use a capacitor assembly, for supplying the reactive power needed by the generator. Currents are injected into this separate winding in such a way that only reactive power is supplied to the generator. Specifically, a power measuring circuit measures the power in the additional set of stator windings, and a power error signal is formed by algebraically adding the outputs of the power measuring circuit. The power error signal is further processed and supplied as a timing control signal for generating the injected currents, which are maintained 90 degrees out of phase with an excitation voltage curve.
