Abstract: Aligned high quality boron nitride nanotubes (BNNTs) can be incorporated into groups and bundles and placed in electronic and electrical components (ECs) to enhance the heat removal and diminish the heat production. High quality BNNTs are excellent conductors of heat at the nano scale. High quality BNNTs are electrically insulating and can reduce dielectric heating. The BNNTs composite well with a broad range of ceramics, metals, polymers, epoxies and thermal greases thereby providing great flexibility in the design of ECs with improved thermal management. Controlling the alignment of the BNNTs both with respect to each other and the surfaces and layers of the ECs provides the preferred embodiments for ECs.

Abstract: A testing cap for a valve body includes a base configured to releasably attach to the valve body and to cover an opening in the valve body. The opening is configured to receive a valve cartridge and the base covers the opening in place of the valve cartridge. The testing cap includes a structure extending from the base. The structure is configured to be oriented relative to the valve body in a first orientation and a second orientation. The structure allows fluid to enter the valve body through an inlet port in the valve body and exit the valve body through an outlet port in the valve body when the structure is oriented in the first orientation. The structure covers at least one of the inlet port and the outlet port when the structure is oriented in the second orientation, thereby preventing fluid flow through the valve body.

Abstract: In the synthesis of boron nitride nanotubes (BNNTs) via high temperature, high pressure methods, a boron feedstock may be elevated above its melting point in a nitrogen environment at an elevated pressure. Methods and apparatus for supporting the boron feedstock and subsequent boron melt are described that enhance BNNT synthesis. A target holder having a boron nitride interface layer thermally insulates the target holder from the boron melt. Using one or more lasers as a heat source, mirrors may be positioned to reflect and control the distribution of heat in the chamber. The flow of nitrogen gas in the chamber may be heated and controlled through heating elements and flow control baffles to enhance BNNT formation. Cooling systems and baffle elements may provide additional control of the BNNT production process.

Abstract: Described herein are processes and apparatus for the large-scale synthesis of boron nitride nanotubes (BNNTs) by induction-coupled plasma (ICP). A boron-containing feedstock may be heated by ICP in the presence of nitrogen gas at an elevated pressure, to form vaporized boron. The vaporized boron may be cooled to form boron droplets, such as nanodroplets. Cooling may take place using a condenser, for example. BNNTs may then form downstream and can be harvested.

Abstract: Boron nitride nanotubes (BNNTs), boron nitride nanoparticles (BNNPs), carbon nontubes (CNTs), graphites, or their combinations, are incorporated into matrices of polymer, ceramic or metals. Fibers, yarns, and woven or nonwoven mates of BNNTs are uses as toughening layers in penetration resistant materials to maximize energy absorption and/or high hardness layers to rebound or deform penetrators. They can be also uses as reinforcing inclusions combining with other polymer matrices to create composite layer like typical reinforcing fibers such as Kevlar®, Spectra®, ceramics and metals. Enhanced wear resistance and prolonged usage time, even under harsh conditions, are achieved by adding boron nitride nanomaterials because both hardness and toughness are increased. Such materials can be used in high temperature environments since the oxidation temperature of BNNTs exceeds 800° C. in air.

The method may include saving the file to a remote file storage location.

Abstract: A method of providing communications services to customer premise equipment (CPE) coupled to a television. The method includes operating a network element as a communications terminal server, the network element being part of a communications network. The network element receives from the CPE a request to initiate communications with a diagnostic system coupled to the communications network. The network element accesses a communications application executing on a communications server coupled to the communications network and pushes a communications interface to the CPE. The network element receives message information from the CPE and routes the message information to the communications server to initiate delivery of a message to the diagnostic system.

Abstract: A coupling system for interconnecting a tube to a valve body is provided. The valve body has a body portion and a nipple extending from the body portion, and the nipple has a threaded external surface and an internal wall defining a bore. The coupling system further includes an adapter having opposing first and second ends, a nut defining a hole through which the first end passes, and a compression fitting located between the nipple, the adapter, and the nut such that when the nut is tightened onto the nipple, the compression fitting inhibits removal of the adapter from the valve body. The adapter defines a passageway extending from the first end to the second end, wherein the first end is received in the bore and the second end is configured to couple to the tube. The nut has an internally threaded surface configured to engage the threaded external surface.

The bonnet nut is threaded to the valve housing such that the control stem extends through the through-bore. Flexible fingers are provided along the through-bore to control a level of resistance to a rotation of the rotatable control stem. The stem is positioned to frictionally engage the flexible fingers as the stem is rotated.
