Abstract: A frame leg for a rack of a switchgear cabinet having two partial profile strips produced from material strips in a stamping and bending process, wherein the partial profile sections overlap each other with partial sections in connecting areas and are fixedly connected with respect to each other. The stability, the torsional stability and sealing of a frame leg of this type can be improved with negligible outlay. Prior to or during the stamping and bending process of the two partial profile sections, the partial sections included in the connecting areas are provided with a curable adhesive layer at least in one of the partial sections, and that the cured adhesive layers connect the partial sections of the two partial connecting sections included in the connecting areas in a fixed manner.

Abstract: A frame member for a switchgear cabinet frame, designed as an inwardly open hollow section having two perpendicular sides that form outer sides of the frame. An easily constructed frame member combines features that provide a simple solution to meeting many requirements of a switchgear cabinet frame.

Abstract: A switchgear cabinet having a framework secured on a frame-like base. The framework has branches and is closed or closable by wall elements and at least one door. In order to design a switchgear cabinet that is as earthquake-proof as possible, a bottom side of the branches of a lower frame of the framework is connected by a plate-like damper frame to the top side of the base, which in turn may be fixed to a cabinet supporting surface.

Abstract: A process for the erection of a switch cabinet and installation of components therein in which portions of the framework of the switch cabinet are assembled to form a partial frame structure. Thereafter, the services are installed and wired within the partial frame structure. The assembly of the framework is then completed and the walls and doors secured thereto so as to form an enclosed switch cabinet with the services installed inside.

Abstract: A rack for a switching cabinet comprising a plurality of frame parts and having fastening holes provided inside of the frame pieces forming internal edges of the rack. The frame pieces form only a frame support. At least a portion of the frame pieces are rigidly or detachably connected to a plurality of mounting rails which extend over at least a portion of the length of a corresponding frame piece, and along with the two profile sides having rows of fastening holes, form portions of internal edges.

Abstract: The invention relates to a method for determining and indicating the quantity of a liquid or solid stored material contained in a container sealable with respect to the atmosphere or any other reference gas pressure, together with a residual volume of the gas interior representing the total volume less the stored product volume, the residual volume being increased and/or decreased after sealing the container by means of a displacer with a freely adjustable displacement size and shape arranged within the container and the resulting pressure change in the residual volume is determined as the measured value for the latter by means of the gas pressure measuring device permanently connected to the container gas zone, so that the corresponding apparatus can be produced with reduced costs and space requirements, has no special sealing problems and simultaneously satisfies at least the same requirements as regards accuracy of measurement and indication, response, adjustability and functional reliability as the known

Abstract: This invention relates to a process for determining and indicating the quantity of a stored liquid or solid material, which is contained in a closed container of constant volume together with a gaseous filling medium introduced into the residual volume of the container interior, kept under a limitedly variable pressure (overpressure or underpressure) and varying from atmospheric pressure. The residual volume or a quantity constituting a measure thereof is measured and, calibrated in units of the stored product quantity, it being reproduced by means of an analog or digital indicating device.

Abstract: Improved method and apparatus for indicating losses of stored liquid materials or penetration of liquid in liquid storage tanks, in connection with a liquid meter. The level change is automatically measured by means of a level meter as a function of time intervals, and a level change not caused by removal or filling under normal operation conditions is indicated as a loss of stored material (such as e.g. due to theft or leaks) or as a penetration of liquid (such as e.g. ground water).
