Abstract: Corrosion protection in hollow metal structures is attained by placing an injected, foam-in-place, closed cell plastic polymer foam into an interior of a hollow metal structure, thereby preventing the ingress of foreign matter, such as dirt or water.

Abstract: A closed loop hydraulic system having a variable charge pressure capability without parasitic power losses is disclosed. The present system includes a variable displacement hydraulic pump driven by a power source, a tilt control means for controlling a tilt angle of the variable displacement hydraulic pump, and a hydraulic motor having a pair of inlet/outlet ports connected in a closed circuit to a pair of inlet/outlet ports of the variable displacement hydraulic pump by way of a pair of main conduits. The system has a charging system including a charge pump driven by a power source, the charge pump including an inlet connected to a supply of oil, and an outlet port connected to the closed circuit for supplying pressurized oil to the variable displacement hydraulic pump.

Abstract: Monolithic films are provided having controlled regional breathability with high WVTR regions and low WVTR regions. The zoned monolithic films are be made by selectively applying adhesive to the monolithic film.

Abstract: An electronic streak camera is described which includes a housing enclosing an objective lens disposed along an optical axis for forming an image of optical radiation from an emissive body, a pinhole field stop at the focal point of the objective lens, a collimating lens for collimating radiation passing the pinhole field stop, a prism for splitting the radiation from the collimating lens into a characteristic optical spectrum of the radiation, an imaging lens for forming an image of the radiation from the prism.

Abstract: Two new adaptive homing guidance laws are developed which are variants of Augmented Proportional Navigation (PRONAV). The first guidance law commands flight path angle rate and is referred to as adaptive matched augmented PRONAV (AMAAP). The second guidance law commands linear acceleration and is referred to as adaptive matched augmented linear PRONAV (AMALP). The major attributes of these guidance laws are (1) they are the solutions of a linear quadratic control problem, (2) they do not require an estimate of time-to-go (tgo), (3) they are matched to a nonlinear model of the target's motion, (4) they adapt in real time to provide optimal guidance over each small segment of the intercept trajectory, and (5) they optimally account for missile deceleration.

Abstract: A locking device is provided for preventing adjacent threaded fasteners from rotating while not bearing any of the preload stress of the fasteners. The locking device includes: a plurality of locking rings, each locking ring being of sufficient diameter to surround the sides of one of the adjacent fastener heads and wherein each locking ring is made from a pliable material such that the locking ring may be deformed to closely fit its associated fastener head; and a torque member, connected to each locking ring, for providing torque to prevent each locking ring and its associated bolt head from rotating.

Abstract: Water-dissipative copolyesters are primer coatings for substantially amorphous polymeric films providing improved ink adhesion and improved slip characteristics. The primer coatings comprise copolyester having repeat units from a dicarboxylic acid component comprising 8 to 25 mole percent 5-sulfoisophthalic acid and 75 to 92 mole percent isophthalic acid and repeat units from a diol component comprising 25 to 100 mole percent diethylene glycol, 0 to 75 mole percent 1,4-cyclohexane-dimethanol, and 0 to 30 mole percent ethylene glycol, based on 100 mole percent dicarboxylic acid component and 100 mole percent diol component. The polymeric films are preferably polyester, polycarbonate or poly(vinyl chloride). These copolyesters primer coatings are generally dispersed in water or water/alcohol mixtures to a solids content of 20 to 35 weight percent.

Abstract: A light weight, thermal battery having a cathode, an anode and a solid complex of SO2 and lithium tetrachloroaluminate as the solid electrolyte therein. The solid complex of SO2 and lithium tetrachloroaluminate is represented by the formula LiAlCl4·xSO2, wherein 1.0<x<4. The thermal battery is activated by heating the battery to temperatures of approximately between 35° C. to 90° C. A method of making the thermal battery is taught.

Abstract: An orthodontic abutment for attachment to a dental implant that is embedded living jawbone having overlying gingiva is set forth. The implant has a gingival surface exposed through the overlying gingiva. The orthodontic abutment is capable of receiving an orthodontic component. The orthodontic abutment comprises a generally cylindrical main body having a lower end for engaging the gingival surface of the implant and a supragingival end opposing the lower end for protruding above the overlying gingiva. The main body has an outer surface between the lower end and the supragingival end. The outer surface includes a roughened portion to which the orthodontic component is to be attached and a gingival portion for contacting the overlying gingiva. The gingival portion extends from the lower end for about 3 mm. The roughened portion typically extends 360° around a central axis of the main body and is preferably adjacent to the supragingival end.

Abstract: Biological toxins are indirectly detected by using polymerase chain reaction to amplify unique nucleic acid sequences coding for the toxins or enzymes unique to toxin synthesis. Buffer, primers coding for the unique nucleic acid sequences and an amplifying enzyme are added to a sample suspected of containing the toxin. The mixture is then cycled thermally to exponentially amplify any of these unique nucleic acid sequences present in the sample. The amplified sequences can be detected by various means, including fluorescence. Detection of the amplified sequences is indicative of the presence of toxin in the original sample. By using more than one set of labeled primers, the method can be used to simultaneously detect several toxins in a sample.

Abstract: A method for removing sulfur from liquid compositions containing aliphatic or cylic organic sulfur-containing compounds, e.g., dibenzothiophene includes activating the sulfur-containing compound by oxidizing either the organic sulfur or adjacent carbon atoms in the presence of a suitable active biocatalyst (ie., microorganism, enzyme, etc.) followed by treating of the activated compound by techniques such as fluidized catalytic cracking so as to remove the sulfur therefrom.
