Abstract:
A hermetic seal between an optical element (22) and a metal mount (24) or housing using a fluoropolymer (26). The fluoropolymer (26) is dispersed along the interior edge of the metal mount (24). The metal mount (24) and fluoropolymer (26) are then heated to a temperature exceeding the melting point of the fluoropolymer (26). Once heated the optical element (22) is pressed into the metal mount (24) and allowed to cool. The metal mount (24), optical element (22) and thickness of fluoropolymer (26) are sized to provide an interference fit between the metal mount (24) and optical element (22).
Abstract:
"Endoscópio flexível com resfriamento hidráulico e pneumático para inspeção de baterias de fornos de coque" consiste essencialmente de um endoscópio (1) montado em um carretel (2) com juntas rotativas (3 e 4) onde é enrolado o corpo em tubo flexível (5), que é dotado de duas mangueiras internas (6 e 7) e concêntricas para a passagem, respectivamente, de cabeamento (8)/ ar comprimido (9) e água refrigerada (10) em direção a ponteira rígida (1 1), que formata uma câmera hidráulica externa (12) e outra câmera hidráulica interna (13), além do compartimento (14) para acondicionamento da câmera lateral (15) e da câmera frontal (16) devidamente arrefecidas pelo sistema de refrigeração e com saídas de ar cónicas (17). É um produto com alto apelo ecológico, por auxiliar na identificação de trincas que deixam vazar para o meio ambiente gases tóxicos e grande quantidade de pó de carvão.

Abstract:
The monitoring system (10) for a gas turbine engine including a viewing tube assembly (32) having an inner end (34) and an outer end (36). The inner end is located adjacent to a hot gas flow path within the gas turbine engine and the outer end is located adjacent to an outer casing of the gas turbine engine. An aperture wall (68) is located at the inner end of the viewing tube assembly and an optical element (42) is located within the viewing tube assembly adjacent to the inner end and is spaced from the aperture wall to define a cooling and purge chamber (72) therebetween. An aperture (96) is defined in the aperture wall for passage of light from the hot gas flow path to the optical element. Swirl passages (80) are defined in the viewing tube assembly between the aperture wall and the optical element for passage of cooling air from a location outside the viewing tube assembly into the chamber (72), wherein swirl passages effect a swirling movement of air in a circumferential direction within the chamber.
