Abstract: A coating process is described that coats a coil-to-coil continuous substrate with a graphene-like coating. The coating process includes cleaning and activating a substrate, applying a graphene oxide dispersion to the substrate, drying the coated sub-strate, and exposing the dried coating to VUV radiation under a dry atmosphere. The atmosphere for the last step includes one or more inert gases and optionally one or more reactive gases to repair defects in the coating and/or to functionalize the coating. This coating process allows for the formation of a polygranular graphene-like coating intimately in contact with the substrate. The graphene-like coating coats the substrate with multiple monolayers of graphene in a continuous manner.

Abstract: A conductive fastener assembly, system, and method are described. The fastener assembly includes a nut having a counterbore formed therein. The counterbore is formed to maintain a sufficient gap between the nut and the protruding end of a fastener sleeve. The nut with the counterbore improves the conductive fastener system such that the need for a solid copper grid and a cap seal is reduced or eliminated.

Abstract: A conductive fastener assembly, system, and method, wherein the fastener assembly includes a fastener, a fastener sleeve, a nut, and a lubricant coating. The lubricant coating is deposited on a distal portion of a fastener shank and is omitted from the rest of the fastener. To overcome the stresses placed on the fastener sleeve by the insertion of the fastener shank largely devoid of a lubricant coating, the fastener sleeve is reinforced by one or more of an increased thickness, a high-strength alloy, and a soft metal coating.

Abstract: The cut laminate edges of aircraft fuel tanks formed of carbon fiber reinforced polymers are sealed to prevent the exposure of carbon fibers to combustible fuel. The edge seal is produced from a prepreg form using a thermosetting resin matched to the characteristics of the resin used in the laminate. The prepreg form can be applied to the cut laminate edges either before or after the laminate is cured. The edge seal acts as a dielectric layer that both electrically insulates the cut laminate edges from the fuel and mechanically contains energetic particles produced at the edges due to lightning strikes or other sources of electrical charges.

Abstract: A system and method is provided for automatically priming a fuel system by bleeding/purging air or vapor therefrom. The system includes a bleed valve configured to automatically move between three positions in response to the pressure of the fuel in the system. When fuel pressure is in a first pressure range, the bleed valve automatically moves to a first-closed position for preventing fuel from draining to the fuel tank and thereby drawing air into the fuel system. When the fuel pressure moves to a second, higher pressure range, the bleed valve automatically moves to an open position for bleeding air out of the fuel system and into the tank, thereby priming the fuel system. When the fuel pressure moves to a third, still higher pressure range, the bleed valve automatically moves to a second-closed position so as to not interfere with the regulation of the pressure regulating valve.

Abstract: The present invention relates to an improved method and system for computing residual statics on shear wave seismic data. The invention uses pilot traces, which are a function of CDP, offset, and azimuth, to resolve shear wave data in the presence of any anisotropy. Statics determinations are made that are not velocity error dependent; the need for CMP to CCP transformations is eliminated. The present invention also relates to a method and apparatus for removing regional anisotropy effects. The present invention, in one embodiment, determines statics for shear wave seismic data by binning seismic data in a bin defined by CDP information, azimuth information and offset information, where a set of binned traces is defined; generating a pilot trace from the set of binned traces; cross-correlating the pilot trace with the binned traces; determining shot statics dependent on the cross-correlation; and determining receiver statics dependent on the cross-correlation.

Abstract: A method of electrochemically roughening an aluminum metal sheet for use as a lithographic plate support comprises subjecting the sheet in an electrolyte to an alternating current treatment. Treatment is performed in the presence of at least one added component, present in the sheet or in the electrolyte, selected from Hg, Ga, In, Sn, Bi, Tl, Cd, Pb, Zn and Sb. The added component accelerates the electrograining, so that only 35-75 kCoulombs per square meter of electricity is required.

Abstract: A traction wheel motion sensor for endless conveyors which is self-cleaning of foreign matter that may enter the traction wheel housing and is spring biased toward the associated conveyor. A traction wheel housing located adjacent a moving conveyor engages the conveyor for sensing the rate of linear displacement thereof, and the wheel drives motion sensing apparatus through a belt. The housing includes a bottom surface which is obliquely oriented to the horizontal wherein foreign matter entering the housing is automatically discharged therefrom and further, the traction wheel is mounted upon apparatus biased toward the conveyor by spring means wherein the traction wheel maintains an operative driven relationship with the conveyor during conveyor operation.

Abstract: Extracting device for extracting a DIP from a DIP header comprises a normally flat member which is positioned between the opposed surfaces of the DIP and the DIP header. The flat member has movable portions which are arcuately movable away from the surface of the DIP header. The movable portions have projecting sections which extend beyond the DIP header. The projecting sections have integral levers which can be manipulated to cause the movable sections to move arcuately along axes which extend parallel to the DIP header. As the movable portions swing upwardly and away from the header, they extract the DIP leads from the terminals in the header.

Abstract: The invention pertains to apparatus for sensing the motion of endless conveyors. A housing, on which a traction wheel having a high friction periphery is rotatably mounted, is located adjacent the moving conveyor member to be sensed, and the housing includes an open end through which a portion of the wheel periphery extends for engagement with the moving member. The wheel rotates a shaft which is belted to the input shaft of a motion sensor, preferably of the electrical type, mounted upon the housing. In one embodiment of the invention the traction wheel is adjustably mounted upon the housing whereby adjustment of the wheel to the moving member is facilitated. In another embodiment the wheel housing is of an elongated configuration utilizing a mounting bracket which may be affixed to the housing at the desired position to accommodate the dimensions of the particular installation.
