Abstract: A modular artillery charge system consists of two distinct solid propellant harge modules. Each module consists of a three-piece combustible cartridge case design and bi-directional center core core ignition system. The three-piece combustible cartridge case consists of a combustible case body, having an open end and a end; a cap, having a closed end and an open end; and a center tube. The closed ends of the body and the cap have a hole in the center. The center core tube is positioned longitudinally through the combustible case body, and contacts the closed ends of both the cap and the body. The bi-directional center core ignition system comprises a core igniter bag and two end igniter bags. The core igniter bag occupies the center core tube, and the end igniter bags contact the core igniter bag. The bi-directional center core ignition system may be ignited by percussion primers or a laser ignition system. The first module is used individually or in groups of two.

Abstract: A projectile to be, fired from a non-rifled tube includes an elongated foody and a stabilizer secured to the tail end of the forebody for enhancing the projectile flight stability and for imparting spin to the projectile. The stabilizer includes a threaded member that extends integrally into a forward section, a peripheral channel and a grooved aft section. The forward section has a generally smooth cylindrical shape. The peripheral channel extends along the entire peripheral contour of the stabilizer and has a generally semi-circular cross-section, for generating an expansion wave and for directing air flow toward the grooved aft section. The grooved aft section is cylindrically shaped relative to a longitudinal axis, and has a predetermined number of identical, equally spaced, circumferentially positioned grooves which traverse the entire axial length of the aft section, and which are angled relative to the longitudinal axis. Each angled groove is defined by two substantially parallel side walls.

Abstract: A system for removing particulates, formed as metal is machined, from coog and lubricating fluid. The system has a tank filled with fluid. The bottom of the tank slopes forward. The tank receives contaminated fluid at its top rear. The contaminants are swarf (chips removed from the workpiece) and fines (which come both from the workpiece and the grinder, borer, or drill). After the swarf is removed from the contaminated fluid by a magnetic filter, only fines remain. The fluid contaminated with fines flows from back to front in the tank, passing under a baffle projecting vertically downward from the top of the tank. A whoosh plate causes the fines to settle out into the tank, while uncontaminated fluid flows over the whoosh plate and is reused. The fines collect at the tank's bottom, from where they are pumped out and mixed with the magnetically-removed swarf for removal.

Abstract: A surface contaminated with toxic materials to be tested or monitored is pled using a probe which is shown here to have a rectangular opening typically of several square inches in cross section. A pliable gasket of suitable heat-resistant material is used to cushion and seal the probe in contact with the surface, but small holes are provided of sufficient size (and positioned close to the surface to be tested) to allow ambient air to be drawn at a desired volumetric flow rate through a sampling tube which also forms the handle of the probe, and is connected through a flexible tube or hose to a suitable detector and vacuum pump. The detector and pump can be combined in a single unit. The detector can be one of several kinds of providing sensitive monitoring of agent vapors or simulant vapors, e.g., a flame photometer or a gas chromatograph (with suitable sampling techniques). Within the probe is mounted a lamp that provides intense heat (e.g.

Abstract: A method is provided for the integration of a low-volume liquid flow and ing system and a portable optical waveguide-based fluorescence detector for the chemical analysis of reagents in fluorescence-based reactions. The method is particularly applicable to the detection of enzyme inhibitors, modifiers, or ligands in cases where a fluorescent enzyme substrate or product exists. In a preferred embodiment, the presence and concentration of acetylcholinesterase inhibitors, such as chemical warfare nerve agents or certain insecticides, is determined by mixing aqueous samples with a dilute solution of n-methyl indoxyl acetate, and monitoring the formation of a fluorescent product (n-methyl indoxyl). The presence of an acetylcholinesterase inhibitor reduces the amount of fluorescent product formed in a given time period.

Abstract: Form-fitting, comfortable, soft-shell protective apparel, commonly called a as mask, for protecting the head, upper body and respiratory tract from chemical/biological agents and toxins and radioactive particles. A unitary, easy-to-put-on, heat and moisture-dissipating multi-layer construction enables prolonged use and internalizes an adjustable suspension system as well as the purified breathing-air path. The latter is structured to enable the self-contained purifying agent to be located away from the face for facilitating weapons compatibility and reducing fatigue. Goggle-like eye lensing is designed to minimize eye relief and maximize peripheral vision and look-down capability, while providing optical correction and laser-light protection. The mask design minimizes dead space leading to distortion and other communications problems, and enables purifying-agent changes in a "hot" environment.

Abstract: An augmented electromagnetic accelerator apparatus which imparts an initial elocity to a projectile by use of enhanced inductance gradients and allows for the use of cylindrical projectiles by the use of a round bore, using a parallel gun rail geometry The enhanced inductance gradients are achieved by the use of an extra turn around the gun rails and enclosing the rail and the said augmented turn in laminated iron. The augmented accelerator has crossovers at the two ends (breech and muzzle end) which have minimum influences over the electromagnetics in the bore of the accelerator.

Abstract: The device of this invention is used to detect small quantities of liquid emical agents in certain pesticides on the basis of the heat reaction between the liquid agent and a chemical oxidant such as sodium or calcium hypochlorite. The detecting device consists of a thin film of resistance heat sensitive element on top of which porous or fibrous substrate material is mounted. This substrate is impregnated with the oxidant material. As a liquid agent contacts substrate it permeates through the substrate and reacts with the oxidant and generates heat. The output volume from the thin film resistance element increases correspondingly. The time from agent contact until this signal is observed as tested is less than one (1) second. The method is directed to the contacting of the liquid agent against the surface, wherein it permeates through the substrate and reacts with the oxidant and generates heat which change in heat is detected by the detecting device.

Abstract: Remote telemetry control in the testing of multiple projectiles such as rets, simultaneously fired, in an environment requiring extremely low power dissipation in the inactive state and experiencing extremely high-G accelerations during launch. On-board battery charging, battery and telemeter conditioning and telemeter control are remotely effected in a highly reliable manner through interfacing a portion of which is on board each projectile and another portion of which is remote from the projectiles and also remotely controlled for safety reasons. The aforementioned on-board functions are prioritized to accomplish first the charging and conditioning requirements, whereby telemeter activation during same is prevented, and the control signals governing charging, conditioning and telemeter operation are electronically isolated to prevent spurious activation. Electronic switching circuitry is incorporated to protectively ensure deactivation of the telemeter during higher priority operations.
