This invention relates to a transformer and more particularly, to a system and method for making a transformer utilizing dynamic magnetic compaction. A coil is placed in a conductive container, and a conductive powder material, such as ferrite, is placed in the container and surrounds the coil and the turns of the coil. A power supply energizes a capacitor which subsequently provides a high energizing current to a second, energizing coil within which the container, material and inner coil are situated, thereby causing the container, powder materials and coil to be compacted to provide an electrical component, such as a transformer, motor, commutator, rotor or choke.

This invention relates to a system and method for consolidating particulate material, such as particulate material, in order to achieve at least ninety-five percent (95%) or even ninety-eight percent (98%) of its maximum theoretical density using a relatively long duration, relatively low current density current flow through the material. In one embodiment, the consolidation system includes a feedback control for monitoring various characteristics associated with the particulate material being consolidated and providing feedback information to a power supply which controls the amount of current supplied to the particulate material in order to achieve the desired density. The consolidation system and method is characterized in that the duration of the current is greater than 0.1 second, but typically less than about 1 second, while the current is less than about 10 KA/cm.

System and method for consolidating powders

A method for using magnetic fields to heat magnetically susceptible materials within and/or adjacent to adhesives, so as to bond, bind, or fasten solid materials to one another. The system uses alternating magnetic fields that induce eddy currents and generate heat within susceptors. An induction heating tool is used to emit the magnetic field at its work coil, and an electronic controller measures the energy being used by a power converter that generates the alternating current driving the work coil which creates the magnetic field. The heating tool is used in a method of adhesive bonding in which the thickness of the conductive layer of the susceptor is in the range of 0.01-3.0 mils, or the heating event time interval is in the range of 0.05-10.0 seconds, or the average power density of the magnetic field at the susceptor is in the range of 10-5000 Watts per square inch.

Method of adhesive bonding by induction heating

An impact device ( ) employing a novel direct electric propulsion system. The device operates by placing a conductive piston ( ) adjacent to an electric coil ( ) then rapidly releasing electrical energy stored in a capacitor ( ) to energize the coil ( ) and propel the piston according to the Lorentz force principal. The system can be designed for a wide range of drive energy, and offers several performance advantages over known propulsion systems. These advantages include simple construction and operation, low manufacturing costs, low drive energy variation, and the ability to adjust drive energy while over a wide range while maintaining low energy variation at reduced levels. The system is adaptable to be powered by either corded electric, or battery, or fuel cell.

Impact device

An apparatus and system for using magnetic fields to heat magnetically susceptible materials within and/or adjacent to adhesives, resins, or composites so as to reversibly or irreversibly bond, bind, or fasten opaque or non-opaque solid materials to one another. The system makes use of the effect that alternating magnetic fields induce eddy currents and generate heat within susceptors, and the effect that alternating magnetic fields additionally induce magnetic hysteresis that occurs in magnetic materials and thereby generate heat. An induction heating tool is used to emit the magnetic field at its work coil, and an electronic controller measures the energy being used by a power converter that generates the alternating current driving the work coil which creates the magnetic field. The distance between the susceptor and work coil is repeatedly analyzed based upon the power converter's input energy, and the work coil is driven at a repeatedly corrected power level during the heating cycle. Once a sufficient accumulated energy has been delivered to the susceptor, the magnetic field is turned off automatically by the tool, thus preventing overheating of the susceptor.

System for consolidating powders

A particulate material heating system and method for heating particulate material having a core which is heated to a predetermined temperature. The core has a plurality of serpentine passages which receive particulate material from a metering device having a plurality of gears which meter the particulate material into the serpentine passages. Gravity causes the particulate material to pass through the serpentine passages such that the particulate material is agitated as it passes through the serpentine passages, thereby causing a substantial portion of the particulate material to come into contact with the core and become heated.

An electromagnetically energized railgun system in which nesting and segmenting of the primary rails is combined with augmenting rails and crossover bar conductors and an inductorless single power supply arrangement to provide a high efficiency hypervelocity capable railgun improvement over prior railgun arrangements. The disclosed railgun apparatus uses a single power supply or energy source and achieves the desired near zero muzzle energy storage through a combination of inductive and resistive primary rail commutation, power supply pulsing, and augmenting rail inductive energy storage.

Augmented hypervelocity railgun with single energy source and rail

An electrical machine which has a rotor positioned within a housing. The rotor has a pair of spaced-apart engagement portions, which, preferably, are tapered. The engagement portions are engaged by collectors or brushes which are arranged in annular configuration around the engagement portions. Retainer support the collectors and serve as electrical conductors with respect to the collectors. Wick elements engage the tapered portions of the rotor adjacent the collectors and provide lubrication and coolant fluid to the collectors and to the surfaces of the engagement portions of the rotor. Actuator mechanisms continuously urge the retainer members and the collectors in an axial direction upon the engagement portions to automatically compensate for wearing action between the collectors and the engagement portions of the rotor. A stator encompasses the rotor to create a magnetic field which encompasses the rotor.
