Abstract: A concrete structure is lined with a statically self-supporting glass shell composed of shell segments which are themselves joined together by sealing strips. In a pipe embodiment of the invention, the shell segments form a ring spaced from the concrete body with the spacing being filled by a backfill mass so that a compressive prestress is provided to the arch shape. When used in a container, the shell may be a laminate of two or more glass layers bonded full surface together.

Abstract: The invention relates to a container for the storage of low-temperature liquids, especially liquefied gases, consisting of an outer container made of reinforced or prestressed concrete, equipped perhaps with a steel dome, and an open inner steel tank, intended to hold the liquid, the steel tank resting on an insulator; an annular space is provided between the two tanks, this space containing a granular insulating material and, in its lower part, a spacer element. In order to protect the steel tank from sliding during an earthquake and in order to absorb the horizontal forces unleashed during such an event, an annular hollow container made of steel is installed between the spacer and the wall of the concrete container, to which it is firmly attached. This hollow container, filled partially with a material that is liquefiable by heating, has some heating elements. The spacer is attached firmly to the hollow container and it is also firmly or tensionally connected to the steel tank.

Abstract: A wedge-type anchor for stranded tension cables. It has anchoring wedges that rest in a conical wedge-reception bore in a wedge mount. The wedges have teeth on their inner surface that decrease in depth toward the point of the wedge. To allow the anchor to be utilized at cryogenic temperatures without the core sliding through and the outer strands breaking prematurely, the ratio of the pitch (8) of the teeth to the diameter of the cable is between 1:20 and 1:30 at a ratio of the effective compression length (11) of each anchoring wedge (4) to the diameter (5) of the cable of between 2.8 and 4.5, and the teeth at the point of the wedge have a contact surface that tapers at an angle (13) of 4.degree. to 6.degree. to the longitudinal axis.

Abstract: A container is disclosed for storing refrigerated liquids, in particular for liquefied gases, which comprises a steel reinforced concrete outer container and a steel inner container inserted into the outer container, where the steel inner container rests on an insulation and where an annular interspace is present between the outer circumference of the inner steel container and the inner circumference of the outer container. The interspace can be fully or in part of its thickness filled with insulating materials.

Abstract: A cooling tower, a process for producing a cooling tower, and a reinforcing element suitable for use in the process and tower are disclosed. The cooling tower, formed from a shell of reinforced concrete, is produced with a plurality of plate-like reinforcing elements adjacent to a surface of the shell. The reinforcing elements are disposed in at least one horizontal plane within the shell adjacent to and suspended from the shell surface. The reinforcing elements in a plane abut and are joined one to another, and are also joined to the shell at spaced points thereon. Each plate-like element includes a central channel communicating with trough-like ends for receiving a suitable reinforcing material which extends into recesses in the shell of the cooling tower adjacent the trough-like ends.

Abstract: The invention provides a climbing framework for erecting concrete forms in the manufacture of straight or curved reinforced concrete walls, with anchoring members for removably anchoring the climbing framework to the wall, and with anchoring elements which as the wall is built, section by section, can be detached from one section and moved up for manufacture of the next-higher section.
