Abstract: A method for allowing a correlation function to be applied to binary codes f length 3 to length 128. A user may specify the desired length of the binary codes for correlation processing; whether the binary code is to use a phase sidelobe level as the threshold or a sidelobe amplitude as the threshold. The user will also be asked to specify the threshold as well as an in phase coefficient referred to as alpha and an out of phase coefficient referred to as a beta. The user may also specify that the codes be expanded which results in correlated compounds having a length twice that of the specified length being displayed to the user. When the user has specified the parameters for correlation processing of the binary code length selected by the user, the program of the present invention will process the binary codes eliminating allomorphic and symmetrical forms of the codes from correlation and then display the results to the user.

Abstract: An accelerometer or seismometer has a pair of flat spirals of optical fiber and has one or more elastic disks bearing a mass and supported for flexure. Each spiral is fixedly attached to a corresponding disk side so that disk flexure lengthens a spiral on one disk side and shortens a spiral on an oppositely facing disk side, the spirals being connected as legs of a fiber optic interferometer so that the interferometer provides an output corresponding to the flexure. A pair of the disks may be mounted oppositely of a sealed body with a pair of the spirals arranged to minimize the effect of pressure changes on the sensor, and a pair of the spirals may be mounted oppositely of a thermally conducting disk to minimize temperature differences between the spirals. The mass may be centrally mounted on a disk with the disk peripherally supported, or the mass may be distributed around the disk periphery with the disk centrally supported for isolation from mounting strain.

The two FMG units produce the bi-directional roll torque characteristic necessary to develop roll-dampening torques for the missile system roll control autopilot.

Abstract: An apparatus for measuring the length of fiber optic cable being deployed om a winch to an underwater environment. The cable deployment measuring apparatus of the present invention comprises a constant current generator for generating a direct current, a resistor array having a plurality of series connected resistors and a plurality of trip wires with one of the trip wires being connected across each of the resistors. The trip wires which function as short circuits are also attached to the cable at predetermined locations along the length of the cable. When the fiber optic cable is being deployed, each trip wire will break when the location at which the trip wire is positioned is unwound from the winch for deployment in the underwater environment. This, in turn, will cause flow through the resistor array with a resulting voltage drop across the array.

Abstract: An electro-rheological fluid damped actuator having an actuator housing w a moveable element such as a piston and rod assembly disposed within the housing. The actuator further comprises a hydraulic circuit with an electro-rheological fluid disposed in the hydraulic circuit. The hydraulic circuit and rheological fluid provides an active and variable damping force on the moveable element. The damping force is controlled by the output of an electrical circuit which creates an electric field within the hydraulic circuit. The electric field will cause the viscosity of the electro-rheological fluid which is exposed to the electric field to increase or decrease in accordance with the magnitude of the electric field. The increase in viscosity of the electro-rheological fluid as it flows through the actuator provides an active damping force on the actuator which allows a more precise control of the output motions of the actuator.

Abstract: 5,7-Diamino-4,6-dinitrobenzofuroxan is synthesized in high yield by aminan of 7-amino-4,6-dinitrobenzofuroxan with hydroxylamine in the presence of strong base such as potassium hydroxide. Acidification of the potassium salt produces a fine powder. Recrystallization of the powder by an extraction process under vacuum in solvents such as dimethylformamide results in large, cube-like crystals which can be pressed to high density explosive formulations. These explosive formulations show high performance as explosives.

Abstract: A biodegradation apparatus comprising an enclosed vessel for holding a large volume of soil contaminated with hydrocarbons. Air diffusers uniformly within the vessel force moistened air through the vessel thereby removing volatile hydrocarbons from the contaminated soil. Outgoing air is supplied to vapor phase bioreactor for the removal of hydrocarbon contaminants from outgoing air. The outgoing air is next supplied to a granular activated carbon filter system which absorbs remaining hydrocarbons and then expels non-polluted air into the atmosphere concluding phase one treatment of the hydrocarbon contaminated soil. Phase two treatment of the hydrocarbon contaminated soil is initiated by utilizing high pressure injection nozzles to force water with surfactant additives through the soil thereby forming at the upper portion of the enclosed vessel a supernatant which includes hydrocarbon contaminants.
