Abstract: A directional borehole drilling system employs a controllable drill bit, which includes one or more conical drilling surfaces. Instrumentation located near the bit measures present position when the bit is static, and dynamic toolface when the bit is rotating. This data is processed to determine the error between the present position and a desired trajectory, and the position of one or more of the bit's leg assemblies is automatically changed as needed to make the bit bore in the direction necessary to reduce the error. The controllable drill bit preferably comprises three leg assemblies mounted about the bit's central axis, each leg having a “toed-out” axle. In response to a command signal, a lower leg translates along the bit axis to cause it to bear more of the bit weight, thus excavating more deeply over the commanded toolface sector and causing the bit to bore in a preferred direction.

Abstract: In one embodiment of the invention, a method of removing a key ring stud assembly comprising a key ring portion and a stud, from a threaded aperture of a gas turbine engine component is disclosed. The method comprises forming a tack weld on the key ring portion of the key ring stud assembly. The method also comprises welding an extractor to the tack weld; attaching a puller to the extractor welded to the tack weld; and removing the key ring portion by pulling on the puller, wherein the stud remains in the threaded aperture. The method further comprises assembling two nuts to the stud. Advantageously, the stud may be removed using a wrench or other suitable tool without damaging the threaded aperture of the gas turbine engine component.

Abstract: A directional borehole drilling system employs a controllable drill bit, which includes one or more drilling surfaces which are dynamically positionable in response to respective command signals. Instrumentation located near the bit measures present position when the bit is static, dynamic and drilling surface position information when the bit is rotating, and stores a desired trajectory. This data is processed to determine the error between the present position and the desired trajectory, and the position of one or more of the bit's drilling surfaces is automatically changed as needed to make the bit dig in the direction necessary to reduce the error. The controllable drill bit preferably comprises three cone assemblies mounted about the bit's central axis, each of which includes a cone and an eccentric cam that rotate about a common axle.

Abstract: A polarity reversal network is provided for a microwave filter that includes a plurality of resonators. The polarity reversal network has a magnetic coupling device that is positioned within an iris of the filter between a pair of the resonators. The coupling device is tunable to adjust its resonant frequency and is used to magnetically couple a signal from a first one of the pair of resonators to a second one of the pair of resonators. The coupling device also reverses the polarity of the magnetically-coupled signal upon the resonant frequency being tuned below a passband frequency of the microwave filter. As a result, the polarity of the signal resembles that of a capacitively-coupled signal.

Abstract: An inductive tuning disk for tuning a resonant frequency of a resonator of a microwave filter. The microwave filter includes a housing that encloses a cavity and a resonator therein. The resonator exhibits a magnetic field that appears in the cavity. The inductive tuning disk includes a dielectric base which is supported from a top wall of the housing by a support, and which is disposed within the cavity at an adjustable height above the resonator. The inductive tuning disk further includes an inductor ring which is disposed over a portion of a top surface of the dielectric base, and which is spaced apart from a center of the base. The inductor ring includes an electrically conductive material. The inductor ring interacts with the magnetic field to cause a resonant frequency of the resonator to vary as a function of the adjustable height. The disk may also be used to couple the magnetic energy between a pair of resonators of a filter.

Abstract: The RF coil and transmission line of a Magnetic Resonance Imaging (MRI) system are remotely tuned for variation from matched impedance conditions (e.g., as caused by variable loading of the RF coil by objects to be imaged which vary from an assumed median object) via a pair of series-connected over-coupled parallel-resonant circuits, each of which includes an adjustable capacitance.

Abstract: An electrostatic deep heating applicator deposits RF energy in a relatively uniform manor throughout a given cross-section of the human torso, thus resulting in a similar uniform heating of the region. The applicator uses a pair of identical, rectangular, flat or cylindrical applicators which generate a heat-producing electric field predominantly parallel to the major axis of the body so as to minimize excessive surface heating. The applicator finds particular use in the treatment of deep seated cancers in patients. It need only be placed near the torso for satisfactory operation, thus allowing a relatively large air gap between it and the patient. It requires very minimum set-up time, is convenient to use and is non-threatening to the patient.

The applicator uses a pair of identical, rectangular or cylindrical applicators which generate a heat-producing electric field predominantly parallel to the major axis of the body so as to minimize excessive surface heating. The applicator finds particular use in the treatment of deep seated cancers in patients. Its dimensions allow a relatively large circumferential air gap when placed around the torso so that it is convenient to use and is non-threatening to the patient.
