    摘要: An improved electromagnetic induction method and apparatus therefor for simultaneously collapsing and propelling a deformable annular-shaped workpiece of relatively lightweight construction in a direction outwardly of the apparatus and along its axis wherein the apparatus is made up of seven different embodiments for carrying out the method. Each apparatus is generally comprised of a framework. The framework includes at least one pulse coil means; and a power supply circuit is connected to the pulse coil means. Annular-shaped surface portions of various embodiments of the apparatus define part of an aperture or passageway for receiving a workpiece and function to position the workpiece in mutual inductance relation to the coil means. The pulse coil means, when energized after positioning of a workpiece in an apparatus, causes the formation of a series of magnetic forces acting on the workpiece that causes progressive collapsing of the workpiece in a direction towards the axis of the apparatus so as to form a slug of solid-like construction and approximately cylindrical or spherical shape. At the same time, the positioned workpiece is accelerated and propelled at a relatively high velocity in a direction outwardly of the coil means and along the apparatus axis. The magnitude of the apex angle, as defined between surface or mandrel portions of an apparatus and the apparatus axis can be varied within limits and is relevant to the magnitudes of the magnetic force components that are generated by a coil means for collapsing, accelerating and propelling a workpiece.

    摘要: A carrying device for electroplating and method for improving the delivery of current therein. The carrying device comprises a core of a high conductivity material and a cladding shrunk around and sealing the core, the cladding having a second, moderate conductivity material which, however, has a high resistance to acidic corrosion. The device further comprises a plurality of electrically conductive clamping members of the second material for clamping an article to be electroplated and for delivering current thereto. Current flow to the clamping members is improved by respective pins consisting essentially of the second material, the pins being forced into respective undersized apertures provided near the clamping members.

    摘要: A new class of composites results from a matrix of fibers, such as fibers of carbon, alumina, ceramics, and aluminosilicates, interwined in a network of fused metal fibers. The composites can be fabricated to have varying surface area, void volume, and pore size while maintaining high electrical conductivity. Composites are readily prepared from a preform of a dispersion of the metal fibers, other fibers, and an organic binder such as cellulose, by heating the preform at a temperature sufficient to fuse the metal fibers and to volatilize at least 90% of the binder. Where a carbon fiber is used, the metal fibers are fused at a temperature causing a loss of less than about 25%, and usually under 15%, by weight of carbon fiber.

    摘要: Improved gun-firing system for electrically augmenting the energy releasedy ignited propellant of the system so as to increase the velocity of the projectile as it launches from the system thereby increasing the probability that it will strike a fast-moving target. The system is generally made up of a barrel and a breech. The breech is provided with a firing chamber for receiving a projectile and an ignitable propellant. In one embodiment, the breech of the system is generally comprised of a detonator, a pair of relatively spaced pressure-responsive switches and a helically wound electromagnetic coil. A power supply is connected by an interlock to the switches and coil such that the coil is not energized until both switches close. These switches close in response to the pressure of the plasma that has been progressively formed from igniting the propellant in the breech chamber. Upon coil energization, eddy currents are induced in the plasma so as to cause further heating and pressurizing of the plasma and resulting in the projectile exiting from the barrel at a greater velocity. In another embodiment, a pair of opposed and relatively spaced electrodes of different and special construction are mounted in the breech and in relation to the chamber. Upon ignition of the propellant by the detonator in the chamber, plasma is formed therein thereby creating a sustained and expanding arc discharge between the electrodes. The arc discharge augments the plasma by ohmically heating and further pressurizing same within the chamber in the projectile velocity.
