Abstract: A beam intensity monitor for monitoring high energy particle beams by placing the monitor across the path of a particle beam to intercept a small portion of the particle beam as it passes therethrough. The monitor comprises primarily a four resistor bridge arrangement driven by a power source and utilizing a voltmeter as a detector for changes in bridge voltage. One of the four resistors functions as the sensor for the monitor. The sensor comprises an elongated wire resistance that is folded, coiled or otherwise shaped to encompass an area or region through which the neutral particle beam is directed to pass. The resistance wire is heated by passage of the particle beam therethrough, being impacted by approximately 0.1% of the beam, causing the bridge to become unbalanced. The magnitude of the voltage produced is proportional to the power in the beam. Simultaneously, phosphor beads attached to the elongated wire are also struck by the particles in the beam.

Abstract: An optically bistable, nonlinear optical device that produces an output that follows two hysteresis loops for an optical intensity variation input at a given frequency. One hysteresis loop follows a clockwise path of development, the other follows a counterclockwise path when the input field or optical intensity is ramped to a large value and returned again to a small value. These features of the device are effectively engineered by controlling the temperature of the input and output faces of the device, allowing optical logic gating and multiplex operation.

Abstract: A method of generating reactive crosslinking sites on the surface of the onium perchlorate particles contained in a Catocene-catalyzed, high-burning rate solid propellant composition by a processing agent which also results in a major improvement in the processibility thereof. The fluid state of the propellant is retained during mixing as a result of interaction between the processing agent prepared prior to incorporating it or when the processing agent is prepared in situ during the propellant mix cycle. There are two alternates available toward improving the processibility of Catocene-catalyzed, high-burning rate propellants. These are: a. The synthesis of a condensation product (processing agent) by the interaction at room temperature of 1,3,5,7,9-pentaazanonane, acrylonitrile, oxiranylmethanol and octadecyl isocyanate in predetermined ratios; or b.

Abstract: A system for measuring the density of certain ions or neutrals within a plasma without probe intervention. When cylindrical symmetry is present, the system also provides measurement of spatial distribution of excited ionic states within the plasma. The system allows spatial distribution of contaminant ions in magnetic confinement thermonuclear fusion devices to be monitored. These functions are accomplished by directing two laser beams through a region containing a plasma. The laser means are at respective wavelengths chosen to be in and closely adjacent to a spectral region near the electronic transition frequency of the ionic species of interest in the plasma. The intensities of the two wavelengths are then measured and compared to obtain the desired data and characterization.

Abstract: A metallographic preparation technique employs a grinding and polishing in our stages, and with multiple steps of each stage, to produce a flat, scratch-free representative sample of a pressed and sintered powder metallurgy material comprised of tungsten, lead, copper, and columbium.The constituents, both hard and soft and in a predetermined weight percent range, are the hard constituents of tungsten and columbium and the soft constituents of lead and copper are finished to yield a sample suitable for microscopic and photomicrograph evaluations since the flatness of the sample and scratch-free surface permits viewing of the shape and size of the individual constituents. The standard prior art metallographic preparation procedure did not produce acceptable results because of the polishing procedure which rounded the refractory constituents and left them in relief. The soft constituents were not scratch free.

Abstract: Poly(diethylene glycol-4,7-dinitrazadecane-dioate), P-DEND), is synthesized y the Michael addition of ethylene dinitramine to methyl acrylate to yield the intermediate compound dimethyl-4,7-dinitrazadecane-dioate (DMDND). DMDND is reacted for a period of about 18 hours with diethylene glycol (DEG) at about 85.degree. C. in presence of a p-toluenesulfonic acid catalyst to yield P-DEND. The product (P-DEND) is purified by passing it through a silica gel column using methylene chloride as solvent. The average molecular weight of P-DEND ranges from about 1500-2000. P-DEND is shown to be compatible with stabilized nitroglycerin for use as an energetic polymer binder for high performance propellants.

Abstract: Refractive elements typically have ground glass edges in areas where the perly-transmitted laser beam does not impinge. Defects on either incident optical surface or the exit optical will produce wide-angle scattering. Some of this scattered radiation will impinge directly upon the ground glass; other scattered radiation will reach it after one or more internal reflections in the optical element: An optical fiber abutted to an edge transfers scattered light to a detector. If a threshold is exceeded, a visual or auditory signal may be generated to alert the operator and/or an interlock may be activated to disable the laser. One photodetector is used to detect returns from several elements. Fibers of different lengths are used to couple the different components into the detector. In this way, a pulsed laser with a pulse length short compared with the delay difference between fibers may be used to identify the individual element which contains the defect.

Abstract: A process for determining the electrical characteristics of a material whin a probe is inserted into the material and an electrical pulse is transmitted to generate a reflected wave which will have a shape which will depend on the electrical characteristics of the material. The probe used has coaxial inner and outer conductors, with an exposed one of the inner conductor extending beyond the outer conductor to establish an electric field between the exposed end of the inner conductor and the outer surface of the outer conductor when an electrical pulse reaches the end of the probe.

Abstract: This device is a modification to the basic auto-tracker function in missile uidance systems, and consist of three new auto-tracker functions. First the gunner has control of an extra set of crosshairs in the tracker output imagery. The gunner will position this crosshair on the desired impact point of the target while the auto-tracker is tracking the target and issuing guidance commands to the missile. The second part is a discrete command issued by the gunner to the auto-tracker. If the gunner decides his impact point selection is better than the auto-trackers impact point selection he simply commands the auto-tracker to enter the aimpoint bias mode. At this time the auto-tracker will stop tracking the old track point and start tracking the part of the image defined by the gunner controlled crosshair. The third part is the filtered transition of the auto-tracker error signal from the old track point to the new track point.

Abstract: Recovery and disposing of waste materials containing inorganic chemicals not be effected by incineration to meet environmental regulations as is the situation with waste organic materials. As long as the inorganic toxic materials are in some soluble form, they can pollute the environment, and, also, end up in the water supplies. Two different disposal methods are disclosed wherein one method is effective for removing the insoluble inorganic salts by converting them into mesylates by reaction with methanesulfonic acid or with methanedisulfonic acid. Most mesylate salts are highly soluble in aqueous and certain organic systems. As an illustration, 1.0 part of silver mesylate or 2.0 parts of stannous mesylate or lead(II) mesylate will dissolve in 1.0 part of water at room temperature. This unique solubilizing property offers the ability of leaching such toxic metal contaminants as lead, cadmium, etc. from sewage sludge. The metal salts can thus be recovered and recycled.

In operation the magazine portion and carrousel portion are aligned and vertically positioned to provide a calculated transit time for the steel ball bearing to drop by gravity to the propellant in the sample cup. Subsequent rotation of the carrousel of about 22.

Abstract: Rate aiding tracking prevents or dampens the effect of large scale target tion on a missile borne tracker during transition of a missile from prelaunch tracking to post launch tracking. Rate aided tracking includes a feedback network responsive to existing stable platforms for combining a tracker output signal with a rate signal that is itself responsive to torques present on a stable platform due to target sensor motion. The feedback network includes an integrator and a transformation circuit and is active only during the missile launching phase of operation when transient effects are manifest.

Abstract: Cadmium sulfide is formed successfully from the reactants hydrogen sulfide md the representative dialkylcadmium, dimethylcadmium, spontaneously when mixed in the gas phase. Reactions are monitored using fourier transform infrared spectroscopy which also permits the identification of gaseous products. The gaseous products of this reaction are identified as methane and ethene. The stoichiometry of the cadmium sulfide depends upon the reactant pressure ratios. The process procedure and sample handling is accomplished using standard vacuum line techniques. This particular process is extremely useful, as the stoichiometry of the product cadmium sulfide can be controlled by the purity of the starting materials and the ratios of reactant pressures. Typical reaction mixtures range from about 14 to 32 torr of dimethylcadmium and from about 30 to about 279 torr of hydrogen sulfide. The cadmium sulfide is formed as a reddish orange powder which is used as a precursor for a single crystal production for detector use.
