  • Patent number: 8092927
    Abstract: A method of forming a gate valve for use in a high vacuum environment of an electron gun by machining a core of non-magnetic nickel-chromium-molybdenum-iron-tungsten-silicon-carbon alloy that is weldable with nickel alloys and has a tensile strength of about 750 megapascals, machining a cladding of nickel-iron, welding the core to the cladding to form the gate valve, and machining the gate valve so as to remove any dimensional differences at an interface between the core and the cladding. In this manner, because the final mechanical tolerance is controlled by machining instead of part assembling, extremely high alignment accuracy is obtained. The final part provides field shielding as provided by the nickel alloy shell, low stray field provided by the non-magnetic alloy, good vacuum performance, and tight mechanical tolerance control.

  • Patent number: 8034266
    Abstract: A process for the production of an open-cell carbon foam from a metallic salt of a lignosulfonate is described. The process includes heating the metallic salt of a lignosulfonate from ambient temperature to a maximum temperature, greater than about 250° C., at a rate sufficiently slow as to provide for essentially uniform heating of the lignin derived material. Heating of the lignin derived material is performed in a non-oxidizing atmosphere having a pressure greater than about 100 psig. The resultant carbon foam can subsequently be optionally subjected to carbonization or graphitization temperatures as desired. The resultant carbon foam has a regular open-cell structure. Densities of the carbon foam products are commonly in the range of about 0.1 g/cm3 to 0.2 g/cm3. The carbon foams may also exhibit compressive strengths of up to about 200 psi. The carbon foam materials potentially have utility as lightweight thermal barriers and in many other of the applications associated with carbon foams.

  • Patent number: 8021747
    Abstract: Provided is a transparent carbon nanotube (CNT) electrode comprising a net-like (i.e., net-shaped) CNT thin film and a method for preparing the same. More specifically, a transparent CNT electrode comprises a transparent substrate and a net-shaped CNT thin film formed on the transparent substrate, and a method for preparing a transparent CNT electrode, comprising forming a thin film using particulate materials and CNTs, and then removing the particulate materials to form a net-shaped CNT thin film. The transparent CNT electrode exhibits excellent electrical conductivity while maintaining high light transmittance. Therefore, the transparent CNT electrode can be widely used to fabricate a variety of electronic devices, including image sensors, solar cells, liquid crystal displays, organic electroluminescence (EL) displays, and touch screen panels, that have need of electrodes possessing both light transmission properties and conductive properties.

  • Publication number: 20110217160
    Abstract: A composite material comprises plies 2, 4, 6, 8, which may be prepregs. Film elements 10 are provided between at least two adjacent ones of the plies 2, 4, 6, 8. The film elements are made from a release material which inhibits adhesion between regions of the resin on opposite sides of the respective film elements, and are randomly distributed. The film elements 10 provide delamination sites within the component. The component may be a test piece for assessing the delamination behaviour of the material. Alternatively, the delamination behaviour caused by the film elements 10 may have a useful purpose, for example to control regions of a component in which delamination occurs following events such as a bird strike on a fan blade of a gas turbine engine.
