20120112026 | APPARATUS FOR SUPPORTING AN ASSEMBLY OF CONFLAT-CONNECTED ULTRA-HIGH VACUUM MODULES - An apparatus for supporting UHV modules and attaching accessories thereto without welding and without obstructing any conflat ports includes a bracket attachable to an attachment feature without loss of vacuum. Embodiments permit arbitrary UHV module reorientation. In some embodiments, a supporting circular groove or series of groove segments is provided in the UHV module, and a clamping bracket fitted with holes meeting optical bench standards is attached to the groove by clamping two clamp segments together while fitting a tongue firmly into the groove. The supporting groove can be located in an extension terminating in a conflat flange, or in a separate UHV extender module. In other embodiments, the attachment feature is a plurality of threaded mounting holes that are not associated with conflat ports, do not require enlargement of the UHV module, and permit attachment of brackets without obstructing any conflat ports and without loss of vacuum. | 05-10-2012 |
20110121515 | MINIMAL THICKNESS, DOUBLE-SIDED FLANGE FOR INSERTION BETWEEN TWO ULTRA-HIGH VACUUM FLANGES - A thin flange for insertion between two ultra-high vacuum flanges includes opposing, parallel sealing surfaces. The sealing surfaces can be surrounded by mounting surfaces having mounting holes therein alignable with holes in the flanges. Forces applied by bolts inserted through the aligned holes are distributed by the flanges so that the thin flange is subjected only to symmetric, compressive forces. Since no deforming forces are applied to the thin flange, the thickness of the thin flange can be less than previously attained, and can be less than 15% of its diameter, or even less than 6.5%. The thickness of the thin flange can be less than 0.28 inches or less than 0.16 inches. Knife edges on the sealing surfaces pressed against soft metal gaskets can form vacuum seals. The thin flange can include a feature such as an inward-facing mounting groove, a threaded mounting bore, and/or an electrical feed-through. | 05-26-2011 |
