Abstract: The present invention teaches a process for manufacturing a flexible thermoinsulating device, which is usable to obtain the thermal insulation of a body having non-flat surfaces. The process starts with obtaining a rigid vacuum panel comprising an evacuated envelope inside which there is disposed a filling material formed of at least a board of open cell rigid polymeric foam, to an operation of localized compression along at least a linear portion of the panel. Through this compression operation at least a slot is formed on at least a face of a board of filling material adjacent to the envelope. The present invention besides relates to the flexible thermoinsulating device obtained through said process.

Abstract: A combination of getter materials particularly suitable to maintain vacuum in devices which cannot be heated at temperatures higher than about 200° C. The getter comprises: a mixture MO/Pd between an oxide of a transition metal MO chosen among cobalt oxide, copper oxide or their combinations and metallic palladium, wherein the latter is present up to about 2% by weight; and a moisture sorbing material. In some applications it is possible to add to this combination a barium- and lithium-based alloy, preferably BaLi4. Getter devices for containing such a combination are also described.
