Abstract: An aerosol generating system for maintaining a constant concentration of aerosol in a chamber is disclosed. The system includes an aerosol generator in a closed chamber. A small fan in the chamber distributes the aerosol within the chamber. A particle analyzer connected to the chamber draws aerosol samples and analyses samples to monitor at least one characteristic property of the aerosol. Typically, these are particulate concentration and particulate size. The system includes a control responsive to signals from the analyzer representing changes in the monitored characteristic property to control operation of the aerosol generator. The control is such as to maintain the characteristic property substantially constant. The system may also be equipped with humidity and temperature control elements for maintaining these factors constant within the chamber.

Abstract: A process of making azidodeoxycellulose nitrate in yields as high as 90 pent. The process initially involves the conversion of cellulose to the mesylate or tosylate derivative. This is followed by reacting the above cellulose derivative with a metallic azide to produce azidodeoxycellulose. Thereafter, the azidodeoxycellulose is nitrated thereby producing azidodeoxycellulose nitrate which is a propellant.

Abstract: This invention relates to a system for detecting, identifying, and quanting hazardous chemicals and radioactive areas, gathering water and soil samples for later analysis and marking contaminated areas under battlefield condition.The invention is comprised of a laboratory enclosure, a viewing port, a non-contact sampling means, a non-contact testing means and a non-contact marking means. Because the system is installed in a protective environment which offers higher electrical power, a highly sophisticated mass spectrometer can be used having the capability to detect, measure and identify known and unknown hazardous chemicals. On-the-move analysis and marking is possible, and operator exposure is reduced. The enclosing of the system also prevents system operation detection.

Abstract: A method of detecting leaks within artillery shells, bombs and other munitions is disclosed which involves the permanent in situ insertion within the munition cavity of an electrically resistive surface which varies in resistance with the adsorption thereon of leaking chemical vapors. In a typical embodiment of the invention, the electrically resistive surface is serially connected with an identical surface with an inert coating and the voltage drops across both the coated and uncoated surfaces are measured. Thereby, any changes in the resistance of the exposed surface due to factors other than adsorption thereon of leaking gases, e.g., temperature changes, are appropriately offset.

Abstract: The invention is an adjustable cheek rest for a hand-held weapon, mounted a stock support tube. Specifically, the invention comprises two adjustable tubes with eccentric bores, mounted about the stock support tube so that the stock support tube fits the bore of the inner adjustable tube and the inner adjustable tube fits the bore of the outer adjustable tube. The outer tube functions as the cheek rest. Each adjustable tube may be rotated about its eccentric bore and reversibly locked so as to vary the position of the cheek rest relative to the line of sight.

Abstract: This invention pertains to end constraints for torsion members applicable r use in cannon breech closing mechanisms, vehicle suspensions, etc. To provide torsion members with greater load carrying ability when subjected to large magnitudes of twist, special end constraints are required. The instant invention features end constraints with substantially square or rectangular cavities having a pair of opposing surfaces contoured such as to eliminate or minimize transverse shear within the ends of the torsion member at the region of transition between the active and non-active portions. These contoured surfaces have opposed oblique surfaces diagonally spaced in a transverse direction with respect to the trailing face of the constraints. To facilitate manufacture, the end constraints can be made to feature surface contoured inserts fixedly mounted within the sockets. It should be ascertained that two end constraints are used to apply moments at the ends of a torsion member.

Abstract: A photoacoustic detector includes an evaporation space for receiving an onic vapor. The space is bounded by a window which is transparent to infrared radiation. A spectrometer irradiates the space with infrared radiation through the window to heat the vapor and acoustically modulate it at a frequency corresponding to the frequency of the infrared radiation. The acoustic modulations are picked up by a microphone which produces a signal which is amplified and used to form a characteristic spectrum. In this way gases or liquid in the space between the infrared source and the window can be detected by examining changes in the spectrum.
