Abstract: A tank gunner obscuration device is provided for automatically and selectively obscuring the view out of the tank seen by the gunner in response to the firing of the main gun of the tank so as to simulate the obscuration produced by smoke, heat and debris during an actual firing. The device comprises a movable shutter which is automatically pivoted between a blocking and unblocking position responsive to firing of the main gun. The control mechanism for the shutter includes an operating solenoid energized by an electrical timer which controls the duration of the obscuration provided. A series of replaceable panels, which are removably mounted in the shutter frame and provide different degrees of opacity, enable the amount of obscuration to be varied.

Abstract: Disclosed is a liquid chromatography process for the quantitative determination of nitro-amines and nitro-aromatics in liquid samples, which comprises directly injecting a liquid sample containing these compounds onto a liquid chromatography column, separating the compounds on the column by elution, and then monitoring the ultra-violet absorbance of the resulting eluant. The instant process finds particular application in the quantitative detection of munitions, such as HMX, RDX, TNT, and their degradation products, in aqueous effluent streams.

Abstract: A physiologic facsimile image of a biological target is obtained by: scang the target by transmitting a microwave signal through the target and measuring at least one of the amplitude and phase components of the complex microwave power transmission coefficient at each one of a plurality of sample locations which are spaced so as to define a two-dimensional array and such that a set of digital data for each of the measured components is obtained, and for at least one of the sets of data; sorting the set of data into column order; magnifying data derived from the sorting step so as to enhance the resolution of the image; mapping data derived from the magnifying step into further data using a predetermined mapping function so as to enhance the contrast between selected portions of the image; and obtaining the set of control signals by filtering data derived from the mapping step using a band pass function which rejects spatial frequencies below a predetermined first frequency and/or rejects spatial frequencies a

Abstract: A rapid and accurate method for calibrating an instrument for measuring the reflection coefficient and complex permittivity of unknown dielectric materials in a lumped capacitance method for an automatic network analyzer is described. The method includes the discovery that the capacitance of the instrument filled with air can be calculated by measuring only the reflection coefficients of the instrument filled with air and filled with a standard liquid of known permittivity, without the necessity of calculating the capacitance value from the dimensions of the instrument. The complex permittivity of the unknown can then be calculated by measuring the reflection coefficient of the instrument filled with the unknown dielectric. Complex permittivity measurements are useful in, for example, evaluating the time course of dielectric dispersions in biological samples.

Abstract: A method for electromagnetic analysis of cellular or cell ghost physiology and pharmacology without disrupting the physcial integrity of the cell membrane is described. The method utilizes the technique of multifrequency automatic network analysis and signal processing to derive complex permittivities from the error corrected complex reflection coefficient of cell containing samples at each measured frequency. Complex permittivity at each frequency is then related to the dispersion in dielectric conductivity (a term which includes ohmic and non-ohmic losses) thereby measuring the ion permeability barrier and transport functions of the cell membrane and ion distribution inside of and outside of the cell membrane. The method measures the complex reflection coefficient of a capacitive termination containing a cellular sample as high frequencies are applied.

Abstract: A portable target raising and lowering device system is disclosed which is used for gunnery practice. A remotely controlled motor arrangement moves the target from a lowered position to a raised position, and back again. The device system is capable of operation with specialized targets used for either simulated visible laser training guns or live fire. When live fire is used, a target is employed which does not engage a motor-actuated control arm on the return stroke and a magnet is used to hold the target in the raised position until the target is hit and knocked to the down position. If the target is not hit, a solenoid is used to move the target to the down position.

Abstract: A finlet injector for external burning fuel injection is provided to obtain a higher performance through a combination of more optimum air-to-fuel ratio and better air/fuel mixing. This is done by capturing (mixing with) a greater quantity of air for a given fuel injection pressure and flow rate. The device is thermally protected and for most flight regimes has minimum drag.

Abstract: Apparatus for measuring rocket motor thrust components and resolving small ector alignment errors. Apparatus includes a spherical air bearing which embodies gyrodynamic principles in order to provide three degrees of angular freedom and in order to achieve stiff, vibration free reactions against translational movement. Effects of thrust misalignment are seen as changes in angular rate which can be measured by encoding rotations of the floated rocket motor inner bearing assembly by use of built-in sensors and/or by motion with an external optical tracker.

Abstract: A video highlight attenuation processor is disclosed which comprises an it circuit from which first and second signals corresponding to an input signal are derived, a peak detecting and inverting circuit which detects and inverts peak portions of the first signal to produce an intermediate signal, and a mixer which combines the intermediate signal and the second signal such that an output signal is produced which corresponds to the input signal with the D.C. level of the peak portions attenuated.

Abstract: An apparatus and method for the recovery of small plastic tissue sections described. A container having parallel sides is rotatably supported on its ends. Slides are placed in the container at an angle. The container is filled with a liquid and the histologic specimens are floated on the liquid within the receptacle. The container is then tilted so that the slides are horizontal and the sections are floating over the slides. A valve allows release of the liquid from the container into a trough. When the water level falls just below the level of the slides the valve is closed and the slides are removed for further processing.

Abstract: A system for locating forward observation posts with respect to a base ston. A continuous electromagnetic wave with frequency f.sub.o is transmitted from an artillery projectile or missile in flight. In addition, a relative time code is transmitted on the same or a separate carrier frequency either from the projectile or from a ground station. The frequency f.sub.o of the electromagnetic wave from the projectile or missile is doppler shifted above or below its basic frequency due to the velocity of the projectile. This doppler signal f.sub.d always goes through its basic frequency f.sub.o or zero doppler at a point which is representative of and identifies an observer's position in the horizontal or subtrack direction of the projectile. This occurs regardless of the observer's distance away from the subtrack. Thus, all observers on a given perpendicular to the subtrack observe f.sub.o or zero doppler at the same time. To locate a specific observer, two projectiles or missiles must be fired.
