Abstract: A multi-stage pressure regulation system, device and associated methodology for reducing the pressure of gas passing through a gas sample conditioning system. The device and method allow for automatic and/or manual configuration settings for regulating different types of gas having different profiles while still avoiding dew point dropout thereby ensuring accurate sample analysis at a downstream analyzer. The pressure regulating device includes a housing having a core, a vapor sample input port, a plurality of openings on an upper surface, a plurality of pressure regulating valves configured to reduce the pressure of a vapor sample, and an assembly having a base and substantially central stem orthogonal to the base and extending axially therefrom, the stem being disposed within the core.

Abstract: Detecting a leak from a site in a sealed system with a source of pressurized gas which is capable of passing through the site, a composition of matter which adheres to the surfaces of the system and which is capable of showing the presence of the gas escaping from the site. The method includes: injecting gas into the system to a pressure in excess of the surrounding pressure, and covering the external surface with the composition to identify the location of the site by the interaction of the escaping gas with the composition. The composition is foam that includes a surfactant which forms a least one bubble in the presence of escaping gas and an indicator which changes color in the presence of the escaping gas. The leak is an opening down to at least the size of a hole 0.001? in diameter. A gas detector may also be used.

Abstract: This invention relates to compositions of matter formulated to work in conjunction with CO2 gas for identifying the exact leak site location of small and large leaks in sealed systems. The leak finding compositions of matter foam, or are in the form of a foam, when applied to the one or more external surfaces of a system, that is closed and pressurized with CO2, where a leak site location is suspected. This foam then changes color from a first color to a second color over the exact leak site.

Abstract: Methods of preventing or treating elevated pulmonary vascular pressure or exercise-induced pulmonary hemorrhage in mammals are provided, the methods comprise administering compositions comprising type V phosphodiesterase inhibitors and an organic base (e.g., meglumine) to the mammal. Compositions, kits and methods of making type V phosphodiesterase inhibitor are also provided. In one embodiment, the composition comprises E-4021, which is sodium 1-[6-chloro-4-(3,4-methylenedioxybenzyl)-aminoquinazolin-2-yl]piperidine-4-carboxylate sesquihydrate and meglumine.

Abstract: An apparatus for testing properties of a product comprising a thermal barrier layer comprises an ignition source, a test stand that extends a sample of the product over the ignition source, and a means for measuring thermal transfer across the sample. The apparatus may further comprise a means for measuring thermal transfer across each layer of the sample. A method for testing properties of a product comprising a thermal barrier layer comprises supporting a sample of the product over an ignition source, heating the sample via the ignition source, and determining a thermal differential across the sample. The method may further comprise determining a thermal differential across each layer of the sample.

Abstract: A bi-layered fire resistant (FR) nonwoven fiber batt and an associated method for manufacturing the same. The bi-layered FR nonwoven fiber batt includes a first, gray, FR layer, formed from a blend of black oxidized polyacrylonitrile (oxidized PAN), white dry polyester carrier fibers and white low-melt polyester binder fibers, and a second, white, layer, formed from a blend of white FR rayon, white dry polyester carrier fibers and white low-melt polyester binder fibers, disposed in a conforming relationship with the first, gray, FR layer.

Abstract: An electrical connector having two correspondingly configured electrically conducting members includes a fail safe mechanism which enhances and maintains the interlocking engagement between the members. The fail safe mechanism includes a latching structures which apply horizontal forces to the connector. These horizontal forces are translated and resolved in a vertical direction such that member retention forces in the vertical direction are increased and electrical contacts among the correspondingly configured electrically conducting tapered elements of the members are increased.

Abstract: A unitary jet impingement plate is formed including a body portion thereof and at least one manifold integrally connected with the body portion, each having internal passages in fluidic communication with one another. At least one jet impingement orifice is provided through a plate of the body portion of the jet impingement plate through which heat transfer fluid can be directed into a fluid jet of such heat transfer fluid from the jet impingement plate and for impinging on a component or object to the thermally effected thereby. The heat transfer fluid may be heated or cooled as required depending on the specific application. Preferably, the jet impingement plate is structurally enhanced by the provision of integral posts provided in a pattern within the body portion of the jet impingement plate. More preferably, a plurality of jet impingement orifices are provided in accordance with a predetermined pattern designed for a particular application.

Abstract: Two electronic components having fine pitch arrays of terminals can be disconnectably interconnected by a multiple electrical connector that includes a pair of intermeshable members. Each of those members has an electrically insulative body with a structured surface including a plurality of tapered elements. Tapered sides of those elements fit flush against each other when the two members intermesh, and the members become strongly adhered to each other when the tangent of the half angle of said tapered sides is no greater than the coefficient of friction of the material of the contacting surfaces. Each of the members has a plurality of electrically conductive segments in position to make good electrical contact when the members intermesh.

Abstract: A hinge apparatus for coupling the component parts of a foldable device is provide. The hinge apparatus comprises a moveable sleeve adapted to tightly fit a guide and stop bushing operably connected with the support components of the foldable device. With the foldable device is in the use extended position, the moveable sleeve may surround and provide support to a hinge link. The hinge link is adapted to permit folding of the foldable device when the moveable sleeve is not surrounding the hinge link. A folding crutch comprising the hinge apparatus is provided. The folding crutch, comprising the hinge apparatus, provides the crutch user with safe, firm and sure support.

Abstract: The adhesive layer of the novel transfer tape contains electrically and thermally conductive particles such as silver which are preferably spherical and are larger than the thickness of the adhesive between particles. When used to bond two rigid substrates together, pressure is applied to the substrates to flatten the particles to the thickness of the adhesive between particles, thus making good electrical and thermal connection between the substrates through each particle.
