Abstract: A suspension arrangement for a thermally insulated tank surrounded by a casing structure. Inside, the tank has a central part from which struts extend away in a star-shape through the exterior tank wall to the casing structure and are connected with the latter. Inside the tank, the struts are guided in gastight connecting tubes which connect the central part with the exterior tank wall.

Abstract: This invention relates to a device for the protection of eyes, electro-optical sensors and sensitive materials against high energy light beams, in which the incidence of a high energy light beam on the element to be protected is detected by a warning sensor. The warning sensor triggers a light source to provide a light beam which, with minimal delay, causes a diminution in the transmissivity of a protective element interposed in the beam path of the high intensity light beam. Due to the extremely rapid response time of these components, the protective response of the invention adapts almost immediately to changes in the intensity of an incident high energy light beam, thereby providing necessary protection and a prompt return to normal transmissivity upon termination of the potentially damaging radiation.
