Abstract:
A ceramic anode structure obtainable by a process comprising the steps of: (a) providing a slurry by dispersing a powder of an electronically conductive phase and by adding a binder to the dispersion, in which said powder is selected from the group consisting of niobium-doped strontium titanate, vanadium-doped strontium titanate, tantalum-doped strontium titanate, and mixtures thereof, (b) sintering the slurry of step (a), (c) providing a precursor solution of ceria, said solution containing a solvent and a surfactant, (d) impregnating the resulting sintered structure of step (b) with the precursor solution of step (c), (e) subjecting the resulting structure of step (d) to calcination, and (f) conducting steps (d)-(e) at least once.
Abstract:
A cryosurgical instrument, comprising a cryoprobe having ducting through which a compressed cooling fluid, such as a cooling gas, flows, for cooling a least part of the cryoprobe. The ducting has an expansion channel having a channel cross-section that enlarges progressively in the flow, direction over a predetermined length such that the compressed cooling gas gradually decompresses, at least partially, beyond a predetermined length on its flow path through the expansion channel while simultaneously cooling down.
Abstract:
An solar tracker bearing comprising a pair of stationary outer bearing races attached on either side of a bearing support element and a rotatable inner bearing race held by the pair of outer bearing races, the rotatable inner bearing race having an beam slot for seating a torque tube beam therein.
Abstract:
The invention refers to a pair of female pants intended to be used preferably by sportsmen and by other active persons and comprising a waist portion (2) connected to back and front portions (3,4), which at the crotch (5) of the wearer are interconnected or merge into each other into a crotch portion (6), which comprises at its inside an air permeable and moisture transporting material layer (7), which attends to that the lower abdomen of the wearer is ventilated. The material layer (7), having a width mainly corresponding to the crotch width of the pants (1) and a length extending a predetermined distance forwards and backwards from the middle of the crotch portion (6), also in a compressed condition maintains an air slot, which makes it possible that air can be circulated over the crotch of a wearer and as well both in a deep direction and in a longitudinal direction through the material layer (7) at the same time as a tempered zone by both air exchanging and the structure of the material layer in an active way drains the crotch portion (6) by that said structure of the material layer (7) consists of a direct from the crotch portion (6) or indirect from a supporting layer (11, 12, 12′, 12′′) fixed to the crotch portion (6) protruding through the same extending air channels (14,21) with surrounding fiber material (7′, 7″) or a flexible thread- and/or strip-formed material (8).
Abstract:
The present invention relates to methods for cleaning semiconductors used in photovoltaic cells and modules, and methods for manufacturing p-n junctions for photovoltaic cells and modules. More particularly, the method comprises providing at least one semiconductor layer of a photovoltaic module and scrubbing the surface of the least one semiconductor layer in the presence of a chemical solution.
Abstract:
A fire suppressant mixture comprising: an organic or supplemental organic fire suppressant compound; a halogen element, and an organic compound, wherein the organic fire suppressant compound, the halogen element and the organic compound are combined such that a boiling point of the mixture is lower than the boiling point of the organic fire suppressant. In some embodiments, the organic fire suppressant compound is FK 5-1-12 and the organic compound is carbon dioxide. In other embodiments, the mixture is supplemented with an additional organic compound such as CF3I or 2,2-Dichloro-1,1,1-trifluoroethane (R123), or an halogen element. In some embodiments an inorganic pressurizing gas, such as nitrogen, is also added.
Abstract:
A device in a valve (1) includes a valve housing (2) with at least a first (3) and a second (4) fluid port. A closure element (5) including a sealing portion (15) and diaphragm (30) is arranged in the valve housing (2). The sealing portion (15) is movable between an open position and a closed position. The closure element (5) and valve housing (2) form a flow passage (11) which communicates with the fluid ports when the sealing portion (15) leaves the closed position. A second sealing portion (14) is arranged in contact with a support portion (25) of the valve housing (2). An abutment element (16) is arranged in contact with the second sealing portion (14). The abutment element (16) transmits a force via the second sealing portion (14) toward the support portion (25) to provide a seal. The force is at least partly exerted by a spring element.
