Abstract: A lightweight, economical, add-on armor plate, ballistic spall liner, installable on the inner surfaces of unprotected vehicles, structures, or other craft. The spall liner provides additional protection to vehicle occupants and internal equipment from the risk of injury or damage due to flying metallic debris, "spall", caused by ballistic damage to the vehicles or the structure's interior when a munitions-type projectile penetrates a wall. The spall liner is a laminate made from layers of high tensile strength, woven fabric such as polyaramid fabric or ballistic nylon which are bonded together with at least one reinforcing layer of martensite sheet steel interposed between the woven fabric layers. The spall liner controls the spall generated by the penetration of a munitions-type projectile by dissipating the projectile's force, framentizing the projectile, and trapping the fragments in the spall liner's interior.

Abstract: An adjustment mechanism for adjusting the relative position of at least two parts. A first movable member has two bores formed therein with a frusto-conical portion formed at one end of the bores. A second fixed member has a pair of threaded apertures formed therein. The apertures in the fixed member have a distance between their axes different from the distance between the axes of the bores. Threaded cams are disposed within the bores and apertures so that rotation of the threaded cams causes an adjustment force to be applied to the movable member.

Abstract: An improved dolly for transporting a shelter. The dolly has bifurcated surting elements which engage alignment studs on the shelter to accurately and quickly align attachment brackets on the dolly with complimentary attachments on the shelter.

Abstract: An improved coupling for driven shafts is formed by juxtaposed bores. A se core is disposed within the chamber formed by the bores. A plurality of radially extending splines are formed and used to rotatably fasten the core and the shafts. Adjustment means are associated with the core to move the core from an engaged position between and connecting the shafts for rotation to a second disengaged position within one of the bores.

Abstract: A portable fire extinguisher designed to increase the discharge velocity and maximum throw distance of the extinguishant. A poppet type valve manually operable to open and close the extinguisher. Tappets placed outside the path of the discharging extinguishant and a smoothly finished discharge passage to provide an obstruction free discharge path. The obstruction free discharge path reduces turbulence and the resultant pressure drop in the extinguishant and increases both the discharge rate and throw distance.

Abstract: A vehicle anchoring device is made with a hydraulic cylinder which is moud on the vehicle and adapted to extend and retract a mounting arm. The mounting arm has an attachment head located on the outboard end of the mounting arm which is adapted to engage a complimentary anchor so as to hold the vehicle in a fixed position even when subjected to a large environmental stress.

Abstract: A device for temporarily attaching two vehicles to form a united structure. he device has a rod which extends from the first vehicle into a complimentary grasping means on the second vehicle. The grasping means can be activated to hold the rod firmly so retraction towards the first vehicle will draw the vehicles together.

Abstract: Turbine powered, self-propelled vehicles utilizing multiple electric motors in sets to comprise part of a novel modular electric powertrain drive system. This novel powertrain system is particularly applicable to larger weight class tracked military vehicles, such as an M-1 tank. However, other large or smaller weight class turbine powered vehicles, are candidates including both track and wheel driven types, as well as certain airborne type vehicles such as helicopters and ground-effect vehicles. The modular powertrain drive system hereof basically comprises a plurality of electric high speed drive motors and also of electrical power generator devices, such as alternators, arranged to be commonly driven by the turbine's effective output shaft.

Abstract: An improved road wheel mounting structure. The mounting device comprises a orsion bar fastened a one end to a vehicle hull. The outboard end of the torsion bar is rotatably supported within a sleeve and is connected to a hub. The hub is fastened to a road wheel arm by means of a plurality of the fasteners in such a manner that normal motion of the road wheel causes a rotation of the torsion bar. But an explosive force applied to the road wheel would rupture the fasteners before a significant bending motion is applied to the torsion bar.

Abstract: A novel control method and attendant apparatus for controlling other various methods/processes by utilizing a photoacoustic effect principle, whether or not the other various processes are with regard to solid or non-solid fluid media, but which other various processes use and require control of a primary excitation high energy beam and related beam-modulating and monitoring apparatus for establishing and detecting a photoacoustic effect. This method and apparatus require the use of appropriate beam generating and beam-generating power control means for controlling such an energy beam, the latter of which may be of the type including laser beams, microwave beams, x-rays and other electromagnetic wave beams, as well as ion, electron, particle, and molecular beams.

Abstract: A rotatable lever and an initially transversely disposed adjustable linkage echanism for attachment in predetermined relation to at least one movable work-performing arm and operable such that upon rotation of the lever and linkage mechanism responsive to pivotal rotary movement of the lever portion thru a designated travel arc of at least approximately 90.degree., the movable arm moves much more rapidly during the first approximate one-half to three-quarters of its designated travel arc, and thereafter continues to move progressively slower in a firm positive manner thru the remainder of the travel arc, while moving from its transverse relationship to a generally parallel or linearly aligned relationship. This simplified mechanism is non-servo in character and relatively low cost compared to servo devices embodying continuous sensing and feedback circuitry. Among various uses are easy association with various known industrial type robot devices embodying programmed control of articulated mechanical arms.
