Abstract: Reaction-brazing of tungsten or molybdenum metal bodies to carbonaceous supports enables an x-ray generating anode to be joined to a preferred lightweight substrate. Complementary surfaces are provided on a dense refractory metal body and a graphite or a carbon-carbon composite support. A particulate braze mixture comprising Hf or Zr carbide, Mo or W boride, Hf or Zr powder and Mo or W powder is coated onto the support surface, and hafnium or zirconium foil may be introduced between the braze mixture and the refractory metal body complementary surface. Reaction-brazing is carried out at or near the eutectic point of the components, which may be influenced to some extent by the presence of carbon and boride. Heating to about 1865null C. for a Mo/Hf combination creates a thin, dense, strong braze that securely joins the two bodies and creates a thin barrier of carbide and boride microphases near and along the interface with the carbon support that diminishes carbon diffusion into the metal body during extended exposures at elevated temperatures (above those presently used in x-ray tubes), even well above the eutectoid temperature.

Abstract: A one-way imaging optical film is provided by a transparent polymer substrate bearing a first coating defining an image area and a second coating defining a background or surround area. In the visible light spectrum, the two coatings have very similar light transmittance characteristics and very similar reverse reflectance characteristics, but different reflectance characteristics such that when the film is viewed from the coated side the image area is visually distinct from the surround area, and when the film is viewed from the substrate side, the film is transparent and the image virtually non-discernible. The film has a visible light transmittance of at least about 25 percent for use especially as an architectural and vehicle window film.

Abstract: A method of manufacturing a target structure is provided. The method includes: obtaining a model structure of an initial material composition having a predetermined geometry and dimensions; applying a slurry mixture into the model structure; and processing the model structure with the slurry mixture inside the model structure to convert the initial material composition of the model structure into a final material composition to obtain the target structure with the final material composition and having a geometry and dimensions that are substantially similar to the predetermined geometry and dimensions of the model structure.

Abstract: Fuel isolation systems, apparatuses and methods are described. In some embodiments, a system comprises a connector coupled inline with a fuel line on a cold side of the fuel line, a valve coupled to the connector, a fluid feed line coupled to a fluid source and to the valve. In the event of an engine fire condition, a control unit outputs signaling to stop pumping the fuel and to operate the valve to introduce fluid from the fluid source into the fuel line. The introduced fluid provides a siphon break in the fuel line such that the only fuel that can pass the firewall is the remaining fuel in the fuel line downstream of the connector and the introduced fluid.

Abstract: Features for in-flight recovery of an unmanned aerial vehicle (UAV). A towline may be deployed by a host aircraft in-flight to recover an in-flight target UAV. The towline or portion thereof may be oriented nearly vertical. The towline may have a fitting thereon. A capture mechanism on the target UAV may have one or more deployable flaps that engage with the near vertical towline and fitting. The flaps may stow to secure the target aircraft to the towline and fitting. The host aircraft may then retract the towline to pull in the target UAV to the host aircraft using a hoist system having a winch. A latching system located in a pylon of the host aircraft, which may be under a wing, may have a towline connector that engages with and secures the target UAV. The host aircraft may have multiple hoist systems for deployment and/or recovery of multiple target UAV's.

Abstract: Fuel isolation systems, apparatuses and methods are described. In some embodiments, a system comprises a fuel tank, a fuel pump, an engine, a firewall, a fuel line from the fuel tank to the engine, a connector coupled inline with the fuel line on a cold side of the fuel line, a valve coupled to the connector, a fluid feed line coupled to a fluid source and to the valve. In the event of an engine fire condition, a control unit outputs signaling to turn off the fuel pump and operate the valve to introduce fluid from the fluid source into the fuel line. The introduced fluid provides a siphon break in the fuel line such that the only fuel that can pass the firewall is the remaining fuel in the fuel line downstream of the connector and the introduced fluid.

Abstract: A system for manufacturing a thermoplastic object may include a robotic arm configured to dispense thermoplastic material, a support apparatus, a computing device and an imaging system. The imaging system may scan thermoplastic material dispensed by the first robotic arm and create a three-dimensional scan model. The model may be compared to a computer model profile to determine if the dispensed material requires adjustment. If the dispensed material requires adjustment, the computing device may adjust the robotic arm or the support apparatus.

Abstract: Disclosed are apparatuses, systems, methods, and devices for generating high-pressure gas such as hydrogen and oxygen. In one aspect, an apparatus is disclosed. The apparatus includes a reactor which includes a pressure vessel containing a metal compound configured to react with a liquid to generate the high-pressure gas when the liquid is available in the vessel. The reactor includes an outlet configured to pass the generated high-pressure gas out of the vessel. The apparatus also includes a receiver configured to store the generated high-pressure gas generated in the vessel and passed to a receiver via the outlet or passed directly to fuel cell or vehicle tank.

Abstract: The present disclosure describes autonomous flight safety systems (AFSSs) that incorporate an autonomous flight termination unit (AFTU) enabling AFSS monitoring for various termination conditions that are used to activate a flight termination system (e.g., in the event a termination condition is detected). Such termination conditions include boundary limit detection (e.g., whether a vehicle position is outside or projected outside a planned flight envelope), as well as body instability detection (e.g., whether a pitch rate and yaw rate exceed some threshold indicative of vehicle instability). For instance, an AFTU may incorporate a three-axis gyroscope sensor and may implement instability detection processing based on information obtained via the sensor. Instability detection processing may include, for example, a BID algorithm that may be implemented by an AFTU to monitor angular rates of the vehicle, to determine if the vehicle is no longer under stable control, and to issue termination commands when termination conditions are detected.
