摘要:
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 apparatuses and also without using additional external containers or precision pump cylinders and pistons ensures that the product stored in the container is reliably and accurately determined.

The present disclosure relates to a frame piece for a rack, comprising a hollow profile which extends along its longitudinal axis and is brought into its cylindrical profile shape by shaping a substantially flat starting material. The hollow profile on two opposite lateral edges, has a connecting zone for closing the hollow profile at least one tab-type projection being formed on at least one of the lateral edges, said projection extending away from the lateral edge of the hollow profile and being shaped such that it can be brought into engagement with at least one corresponding receptacle on the respective other lateral edge in a clamping or positive manner.

The present disclosure relates to a sealing element for hollow sections, including a seal carrier that extends along a longitudinal axis and has two arms each of which has an outer face and an inner face and which are connected together, as one piece, at longitudinal edges that face each other such that they form a corner angle between them seals mounted on or near a free longitudinal edge of each arm and running parallel to the free longitudinal edge, on the outer face of the associated arm, and a securing device, on at least one inner face of an arm, for detachably securing the sealing element onto a corner of a hollow section. A cover cap serves to complete the sealing elements, the cap being provided, on its outer face, with one or more sealing sections designed to connect to ends of the seals of the sealing element.

The present disclosure relates to a method for producing rectangular or square wall elements from flat sheet metal, including determining a length and width of a wall element, providing a flat sheet metal piece incising two longitudinal edge portions to form two incisions to form two tabs for each longitudinal edge portion separated by a respective incision from the remaining longitudinal edge portion, right-angled folding of a respective strip, formed by the incisions, right-angled folding of the tabs parallel to the longitudinal edge at the level of the base of the associated incision, right-angled folding of the longitudinal edge portions along the longitudinal edge, right-angled folding of the transverse edge portions parallel to the transverse edge to form a strip having a width corresponding to the transverse dimension of the tabs, and right-angled folding of the transverse edge portions along the transverse edge.

The air conditioning device for electronic components features three channels (6, 7, 8) for two flowing fluids that are in heat exchange with one another. In the first operating mode these two fluids are guided by means of switchable flaps into two selected channels (7, 8) where they are in heat exchange with one another at a partition (12) that is equipped with heat exchange elements (12, 13). In a second operating mode the flaps are switched in such a manner that the two fluids are in heat exchange with one another at a Peltier element (9) that is equipped on both sides with heat exchange elements (9, 11). In a third operating mode the Peltier element is switched as a heating element. In the first operating mode on the other hand the Peltier element is deactivated and consumes no electric energy.
摘要:
A control cabinet having a cabinet body with opened sides which can be closed at least partially by one or more side walls. An air conditioning device which is placed near at least one side wall rejects heat generated inside the cabinet body or guides it towards the inside of the cabinet body. This invention simplifies the design of the air conditioning device. For this purpose, an intermediate wall which is parallel to the side wall and located at a distance therefrom, is placed in such a way that it is oriented towards the inside of the cabinet body. In addition, the air conditioning device is placed in the intermediate space surrounded by the side wall and the intermediate wall.

A control cabinet with an air conditioning device mounted inside the control cabinet and physically connected to the inside of the control cabinet via an air condution channel. The inside of the control channel is surrounded by side walls and at least one door. This invention provides efficient air conditioning inside the cabinet. For this purpose, an intermediate wall is placed at a distance from the side wall and an air collecting channel created between the side wall and the intermediate wall is physically connected to the air conduction channel of the air conditioning device through input openings and to the inside of the control cabinet through at least one passage.
