    Abstract: Method and apparatus are presented for the generation, regeneration, and transplantation of field enhancing whiskers to provide for an improved cathode in flat panel displays in particular, and in other applications. Such applications comprise devices in which there is an emissive cathode structure for producing electrons. There are clear advantages for the instant invention in the case of a flat panel display which requires a relatively large cathode area, because the present invention avoids excessive power loss due to radiation and conduction loss by permitting operation of the cathode at a significantly lower temperature than if it operated solely as a thermionic emitter. The combination of moderately elevated temperature and enhanced electric field allows the advantages of thermo-field assisted emission.

    Abstract: A number of metal cores especially suitable for use in an electrical induction device such as a transformer are disclosed herein along with respective methods of making these cores. In accordance with each of these methods, the appropriate metal material is initially provided and thereafter formed into an unsolidified, preliminary shape. Thereafter, while the material is in its preliminary shape, it is densified, preferably by means of explosion bonding, whereby to improve its permeability and saturation field characteristics. In one embodiment, a metal material is initially provided as a continuous strip. In another embodiment, the metal material is initially provided as a number of plates and still in another, preferred embodiment, amorphous metal particulate material is utilized. In this latter embodiment, the orientation of the particulate material is controlled to further improve the permeability and saturation field characteristics of the ultimately formed core.

    Abstract: A cable for cryogenic use includes an inner conductor and a solid polymeric insulator loosely positioned about said inner conductor above 0.degree. C. A collapsible spacer can be positioned between the inner conductor and the polymeric insulator to further space the insulator away from the conductor and thereby accommodate greater shrinkage of the insulator. In fabricating the cable, the cable is sealed and pressure is applied to the cable to expand the insulation. The cable is placed inside a rigid cylinder having an inside diameter larger than the outside diameter of the cable. The cylinder is heated to facilitate expansion of the insulation, and the cylinder is subsequently cooled while maintaining pressure to the cable.

    Abstract: A cable such as used in cryogenic and superconductive applications includes an inner conductor, an outer conductor or shield, and a solid dielectric between the inner and outer conductors. The dielectric is introduced into the space between conductors in liquid or gaseous form, preferably under pressure, and the temperature of the dielectric is lowered to or below the freezing point for the material. Pressure relief should the solid dielectric suddenly vaporize by rapid heat rise is provided by holes in the outer conductor or by scoring the inner surface of the outer conductor to provide rupture points in the conductor.

    Abstract: A high-voltage DC transmission system and method is characterized by a minimum filtering requirement as to ripple as well as to surge and harmonics. Use of a superconducting generator directly coupled to rectifying means eliminates the requirement of a step-up transformer and allows operation at high frequency for minimizing ripple (and related filtering).

    Abstract: Optimized shielding configurations for longitudinally extended tiered insulators for electric power equipment is described. An insulator comprises a central core with a plurality of annular shields and radial partitions defining convoluted paths between the environment and the surface of the central core. An optimizing relationship of core diameter, tier separation, free path length and total path length between the outer surface and the inner core is disclosed for constructing insulators with maximum lifetime in contaminated environments. Selected generalized insulator configurations are disclosed which embody the invention. Also embodied in the invention is the addition of molecular sieve, insulating grease, or adhesives on the outer edges or lips to sorb out contaminants before they can reach the inner insulating surfaces.

    Abstract: Underground electrical equipment such as a transformer or cable is prevented from thermal runaway by back-filling the trench in which it is laid with a soil which includes water entrapped in highly water-absorbent hydrophilic polymeric gel particles soaked with water. The water-soaked particles preferably are coated with a water-impermeable film. The water may also be entrapped in liquid form in small balloon-like containers. Also, a water impermeable sheath may be formed around the back-fill soil to minimize evaporation from the particles.
