Abstract: A lifting yoke for containers consists of a central beam (1) and two coaxial extending beams (2, 3) guided for reciprocating movements by the central beam and capable of telescoping one into the other. A guide tube (4) arranged coaxially inside the extending beams is able to connect them together when they are extended one from the other and to guide one of the beams into the other when they are telescoped one into the other. The telescoping mechanism (5) for the lifting yoke consists of a hydraulic cylinder (9) with driving wheels (10), two pulleys (11, 12), a cable (13) running over the driving wheels and the pulleys, and protruding rods (14, 15) attached to the cable for operating the extending beams (2, 3).

Abstract: Tanks, containers, pipes, etc., of sandwich construction may be manufactured by winding an inner sheet (3) onto a rotating mandrel (1), by then winding a hard insulation (8) which has been softened by heating in a microwave oven (9) onto the adhesive-coated inner sheet, and finally by winding a cover sheet (12) onto the adhesive-coated insulation layer.

Abstract: A tank container comprising a framework (1-4) and a tank (7) disposed therein.The tank (7) is secured in the framework (1-4) by means of members (8, 11) transmitting tensile forces in the axial and radial directions of the tank wall so that no bending moment is exerted on the tank wall. These members are preferably radial suspension plates (8) between the ends of the tank and the corners of the end frames and axial fastening plates (11) between the cylindrical portion of the tank and the corners of the end frames.

Abstract: The invention relates to an insulated tank container. In order to obtain a particularly light and cheap construction, the tank container consists of a thin inner shell (4) and outside this semi-hard or hard insulation (6, 8, 10, 11) which has the capacity to take up and transfer stresses in various directions and is firmly glued to the inner shell. An outer shell (5, 7, 9) with a framework (1) may be disposed outside the insulation. As an alternative, the insulation may be introduced, foamed and hardened in situ between preformed shells.

Abstract: Method of emptying a powder or like material out of a container.The powder (9) is conveyed out of the container (1) from its free upper surface by means of a stream of carrier air in a carrier-air pipe (6; 10; 12) provided with openings for the powder. The emptying is facilitated by means of a stream of secondary air from a secondary-air pipe (7; 11; 13). The container is rotated so that the fixed carrier-air pipe may come into the vicinity of the surface of the powder.
