A rotary propulsion engine system designed to propel a craft. Such a rotary propulsion engine system comprises at least two reaction masses or armatures, at least two reaction mass driver assemblies, at least two travel pathways for said reaction masses or armatures, two counterrotating discs housing an equal number of the at least two said reaction mass driver assemblies, and a counterbalancing means used to maintain a balanced distribution of masses about the axis of rotation of each counterrotating disc in order to maintain a zero horizontal torque sum as each reaction mass or armature moves along its ballistic trajectory. Reaction masses are fired into a rotational environment wherein the kinetic energy of said reaction masses is recycled, thereby reducing or eliminating the need for chemical propellant-based propulsion systems, and transporting heavy, finite, and expensive fuels for combustion.

An electromagnetic launcher with a curved or spiral-shaped, open-ended guideway and conductors for launching a projectile. The projectile, movably retained on or within the guideway, is accelerated along the guideway using electromagnetic forces until it reaches an end of the guideway, then the projectile is launched in a desired direction. The direction of the launch of the projectile is determined by orienting the guideway in the desired direction using an actuator.

An electromagnetic impact drive includes two electroconductive helical springs in meshing relationship, with their fixed ends supported on an abutment and their movable ends joined to an electroconductive armature. Electric terminals connect the fixed ends to a electricity source for feeding a current to flow from one of the electric terminals via an associated one of the helical springs in a first direction towards the armature and from there in an opposite second direction via the other one of the helical springs to the other one of the electric terminals so that adjacent windings of the helical springs repel one another by an oppositely directed force pair when an electric circuit is closed. A control device is provided to open and close the electric circuit with the electricity source.

Systems and methods for electromagnetically controlling the muzzle velocity of a conventional gun using a coil gun on a barrel extension. This method can also provide an electromagnetically induced increase to muzzle velocity beyond that capable by conventional explosives. With higher muzzle velocity, the weapons will have longer range, higher penetrating power and stand-off distances. A section of coil gun can also be used to center the projectile in the barrel to control the exit trajectory. Using a coil gun to control muzzle velocity and center the projectile can be a retrofit to existing weapons that would greatly increase their down-range accuracy.

A jewelry display includes a ferromagnetic planar substrate having a front surface opposite a back surface. A bracket is configured to be attached to a wall, the bracket comprising at least one bracket magnet which is a permanent magnet.

A launch acceleration system can include a passage, a plurality of magnetic components, and a control system. The passage can include an entry region, a projectile acceleration pathway, and an exit region for a moving projectile having a magnetically susceptible portion. The magnetic components can be arranged around the projectile acceleration pathway such that the moving projectile travels through the magnetic components. The control system can be coupled to the magnetic components and can be configured to actuate the \magnetic components at one or more proper times to facilitate one or more applications of magnetic force from the magnetic components to the moving projectile as the moving projectile passes through the projectile acceleration pathway in a manner that accelerates the moving projectile.

A magnetic projectile launching system includes an accelerator having a plurality of electromagnets positioned around a circular accelerator pathway. Each electromagnet includes a frame supporting a core having a passageway surrounding the pathway. A conductive coil is wound around an outer surface of the core. A plurality of capacitors are mounted on the frame and electrically connected to the coil. The capacitors are operable to switch from an on-state to an off-state sequentially to form a moving magnetic field which accelerates a projectile around the pathway. At least one of the electromagnets is a movable electromagnet operable to be moved from a first position to a second position. When the movable electromagnet is in the first position, the accelerator is operable to accelerate the projectile around the pathway. When the movable electromagnet is in the second position, the accelerator is operable to launch the projectile tangentially from the pathway.
