Abstract: A closed loop current controller for an electromagnetic rail gun. It is necessary to control the muzzle velocity of a rail gun accurately for the gun to be a good artillery device. The present invention provides a closed loop control system to accurately regulate the energy transfer to a rail gun projectile and control its muzzle velocity. The rail gun control system includes a state space (state domain) control concept adapted to discrete control events that transition the system from one state to another until the final desired state (i.e., muzzle velocity) is reached. The control regulator preferably generates state transition functions that transition the projectile from state to state according to a defined current profile to provide a specified projectile muzzle velocity. The rail gun closed loop current controller also includes current reference compensation to correct for errors in previous state transitions.

Abstract: A linear cavity is provided on the leading edge of an object that is subject to the flow of liquids or gasses, where said cavity preferably has a wall that follows the curvature of a diminishing sine wave, although other configurations are possible that do not follow a specific sine wave. The cavity accepts the flow of liquids or gasses that enter into the cavity, and where the dimensions of the cavity cause the flow of liquids or gases within it to form a pressure node that extends forward of the cavity. The pressure node provides a wedge means to cause oncoming gasses or liquids to divert around the object body ahead of the object body itself, decreasing turbulence around the periphery of the object. The cavity may be spherical, in the instance of a missile, plane, or underwater transportation means, or may be linear, in the instance of an automobile grill that is subject to wind, or a bridge support, where the bridge support has to maintain position against the flow of current.

Abstract: A counting mechanism for detecting and registering the number of rounds fired from a recoil gun includes a housing that can be mounted to a component of the gun that exhibits recoil motion upon firing of a round. A counting device is contained within the housing and includes an actuator that is activated by the recoil motion of the gun component upon a round being discharged. A weighted mass is movable within the housing with the recoil motion of the gun component, and the actuator is operably configured with the mass such that movement of the mass resulting from the recoil motion actuates the actuator and increments the counting device.

Abstract: A firearm barrel assembly having a gun barrel with a muzzle opening on a distal end, a shroud coaxially surrounding at least a portion of the barrel, the shroud having a distal portion extending beyond the muzzle opening defining a shroud front region having a distal end portion, a proximal portion extending proximally from the muzzle opening defining an annular region between the barrel and shroud, the shroud front region and annular region in fluid communication with substantially no obstruction between the shroud front region and the annular region, and a front wall disposed at the distal end portion of the shroud. The wall has an opening to allow passage of a projectile fired from the firearm.

Abstract: A device for monitoring tiltable flaps on aircraft wings including rotary sensors at the rotary axis of the flap and associated with each actuating element. A rotation sensor is connected to the actuating elements by a spring band. The band is a coupled for angle transmission and the band is connected at a distance from the rotary axis. The spring band is stiff in the direction of rotation, while in the lateral direction, for the purpose of compensating for transverse movements of the actuating elements, the spring band is soft. For each flap, the signals of the rotary sensors, at decentralized monitoring devices to locate errors, are transmitted to an evaluation unit.

A second chamber is coupled to the processing chamber and features an electron source which produces a high energy electron beam. The high energy electron beam is injected into the processing chamber where it is shaped and confined by a means for shaping and confining the high energy electron beam. The high energy electron beam produced in the second chamber when injected into the processing chamber ionizes the halogen gas creating a dense, ion-ion plasma in the processing chamber that is continuous in time. A method for creating an ion-ion plasma continuous in time.

Abstract: For use in estimating or predicting bioaccumulation of a chemical analyte, even a surfactant, log Pow values for the analyte may be determined by calculating the log of the ratio of the concentrations of the analyte in n-octanol and in water, equilibrated using a slow-stir method. In this method, samples of the analyte are prepared and stirred in n-octanol and water (or other largely immiscible solvents) at a rate sufficiently low to avoid emulsions over time at a constant temperature. After stirring, the n-octanol layer and the water layer are sampled and the quantity of analyte in each measured.
