  • Mixed-mode symbol removal method for facsimile data compression
    Patent number: 4703362
    Abstract: A method for data compression provides for an improved digital facsimile ument transmission system. The mixed mode method provides that symbols can be located both individually and as a part of a line of symbols in order to provide for efficient operation for both the symbol and graphic portions of a document to be transmitted without requiring that the symbols be organized in lines or that each location be conveyed independently of all other locations of symbols.

  • Binary chemical warhead
    Patent number: 4699061
    Abstract: Hardware and method are disclosed for mixing at least two non-toxic chemical compounds in a warhead for missiles and artillery projectiles to form a toxic agent during their ballistic travel to a target. The inventive design avoids danger from spills of toxic agent during shipment, handling or storage of chemical ammunition by not allowing the constituents of such agent to mix until shortly before the ammunition impacts the targets.

  • Highly decoupled cosited antennas
    Patent number: 4700196
    Abstract: Two cosited omnidirectional biconical antennas are respectively tilted plus nd minus 45 degrees (.+-.45.degree.) with respect to the vertical and, therefore, are perpendicular (90.degree.) with respect to each other to effect polarization mismatch and near field decoupling. In combination with the described antennae orientation, high impedance cable chokes are added in series with the coaxial cable antennae feed lines to suppress induced parasitic rf currents.

    Patent number: 4699084
    Abstract: A high pressure furnace and reusable demountable containment means for setive in situ information of epitaxial layers on a semiconductor substrate while under gas overpressure. The containment means has vent means therein for allowing the inert and reducing or reactive gases in an inner chamber of the furnace to enter into the interior of the containment means to equalize pressures on each side of the housing and to semi-confine the vapor from the epitaxial growth source materials in the interior of the containment means. The containment means has a removable, i.e. demountable, form-fittedly sealed plug which is removed to insert the substrate and growth source elements, which are mounted in a close-space relationship on a support structure, therein. The support structure is inserted back into the containment means and the plug is form fittedly sealed thereto for performing the epitaxial layering.

  • Resonant free platen for vibration testing of test specimens
    Patent number: H338
    Abstract: This invention relates to a system for vibration testing of specimens using n electro-dynamic shaker. It overcomes the various undesirable consequences which attend the existing technology and methodology, which uses a constant thickness flat plate platen, by using an inverted, truncated pyramid type of platen, with both the base and top of square-rectangular-parallelpiped shapes, attached to a cylindrical shaker head. The outer portion of the platen has a very low mass and the section modulus is very high at the line of bending thereby increasing the resonant frequency of the platen while lowering the total weight of the platen, because there is less mass around the perimeter of the platen. The optimum shape of the pyramid is determined by a means which can be expedited by use of the computer program.

  • Fiber array reinforced kinetic energy penetrator and method of making same
    Patent number: H343
    Abstract: An improved fiber reinforced penetrator rod for a kinetic energy projectile aving enhanced penetrating strength is disclosed herein. Embedded in a matrix medium of depleted uranium, or liquid phase sintered tungsten, are long fibers of tungsten-hafnium-carbide which are knitted into a continuous weave over the entire length of the fibers. This prevents splaying open or splitting of the front end of the fibers, and hence of the whole penetrator rod front end, upon impact, penetration, and receiving of the compressive forces upon hitting an armor target.

  • Inert solid compositions which become chemically reactive when molten
    Patent number: H349
    Abstract: A reagent composition which is chemically inert when solid and is chemica reactive when molten comprises a first substance selected from high molecular weight waxes and polymers and a second substance dissolved, dispersed, or encapsulated in the first substance. The second substance is highly chemically reactive and is selected from strong bases and strong acids. The composition is particularly adapted for use in safety devices automatically activated in response to an increase in the temperature of a chemical system and in processes for automatically discontinuing the operation of or decontaminating the products of a malfunctioning chemical system.

  • Linear algorithm for non-linear interpolation for computer aided designs
    Patent number: H354
    Abstract: The linear algorithm described differs from other artificial intelligence ograms in its operation over a continuous representation. In the algorithm, the size of the exponent is tied to the magnitude of the learning base employed, and the design thus becomes more selective as the learning base grows. With it, "run time" and "chip size" can be analyzed in substantially linear time.

  • Electromagnetic projectile launchers
    Patent number: H357
    Abstract: These electromagnetic guns or launchers comprise a pair of switching rails ith a slidable switching armature associated therewith for commutating a high direct current into a pair of projectile rails which are arranged in tandem with the switching rails and are electrically connected thereto. The kinetic energy of the switching armature is transferred to the projectile armature assembly so that the projectile armature assembly has an initial velocity as the current is commutated to the projectile rails. The projectile armature assembly may be mounted on and carried by the switching armature during its entire travel or the switching armature may bump the projectile armature assembly into the conductive breech region of the projectile rails at the end of its travel.

  • New energetic polymer, P-DEND
    Patent number: H365
    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.
