Abstract: A multilevel container having a circumferentially continuous wall or bottom elements of sheet metal with radially outwardly beaded end faces. The wall and bottom elements are placed on top of each other on butt joints so as to seal the end faces and are detachably braced with a minimum of one neighboring container level. The multilevel container also comprises one or more sealing rings and bracing components that act on neighboring end faces. In order to provide a readily manufacturable and form a stable multilevel container without multiple beads in alternating directions or weldings in the butt joint portions, a separate and independent shape retaining ring is provided. This ring reinforces the container and has shape retaining surfaces on its two end faces. In the region of their end faces, the neighboring wall and bottom elements are set on and tightly braced against the shape retaining surfaces of the reinforcing shape retaining ring.

Abstract: The invention relates to a filter arrangement comprising a plate-shaped filter holder (12) provided with at least one stem-type protruberance (13) having an opening (11) said filter holder (12) being used to receive a filter element (14) in a sealed manner for each protuberance on the raw gas side of the filter holder. In order to ensure that the filter is changed easily with sufficient filtering safety, each filter element (14) is provided with an adapter collar (15) comprising at least one limb (15B; 15D) parallel to the protruberances. Said limb can be placed, from the raw gas side, inside or over the protruberance. A sealing arrangement (16) provided comprises sealing elements (16A, 16B) which are parallel to both the plates and to the protruberances and are used for the at least partial join between the protruberance and the adapter collar.

Abstract: A Vacuum conveying apparatus with a weighing and metering device, comprises a separation container (10), acted on by a vacuum, for intermittent intermediate storage of material conveyed in a suction gas flow, a force isolation means for entry of conveyed material into the separation container (working side), a weighing device (50) for, in particular, continuous weighing of the separation container, as well as a vacuum pump (70) and a controller. In order to create a vacuum conveying apparatus that can guarantee a more precise weighing and/or a more accurate stipulation of the timepoint for turning off the vacuum pump or for interrupting the suction process during the ongoing conveyance process, the vacuum pump (70) is isolated in terms of force from the separation container (10) and is also situated such that it is not weighed.

Abstract: A Vacuum conveyor device (10) with a multi-stage filter system, has at least one inner filter (10A), one outer filter (10B), and one filter adapter (20) especially for air-tight and/or fluid-tight insertion of at least one of the filters, for which the outer filter is arranged up-stream of the inner filter. In order of preparing a filter system for a vacuum conveyor device, which features both the cleaning-related elements of conventional filters and also the safety-related advantages of multi-stage systems, but which remains compact in structure, the one or more inner filters (10A) are used as carrier units for the one or more outer filters (10B) that can be mounted on or inserted into these inner filters and can be connected or are connected to the filter adapters (20).

Abstract: A multi-stage ejector pump having an ejector nozzle system with the nozzles situated coaxially behind each other and axially set apart from each other by a spaced distance. The ejector a nozzle system is made up of a set of individual nozzles and nozzle spacers. The ejector nozzle system can be sealingly pushed into a nozzle-receiving shaft of a housing element. The housing wall is interrupted in the area between adjacent nozzles to provide a fluid connection to suction chambers. Each individual nozzle is provided with support elements on its outer periphery. The support elements are axially set apart and provide tilt-free or low-tilt support in relation to the wall of the nozzle-receiving shaft. The aim of the invention is to provide a multi-stage ejector pump which has compact construction, interchangeable nozzles and a high degree of efficiency.

Abstract: A device for the removal and controlled reduction of the amount of liquid remaining on a flat stock is provided. The device is provided for coacting with a moving section of elongated flat stock, such flat stock moving in a direction generally parallel to the opposing edges such as after rolling process. Liquid used for lubricating during forming of the flat stock is removed by a gas stream which flows across the film of moisture transverse to the direction of motion. The device comprises a plurality of exhaust chambers which are open toward the edge of the flat stock, each of the exhaust chambers always located between two adjacent rolls and formed jointly by the rolls in at least one housing unit. Included in the housing is an exhaust chamber and exhaust port for exhausting a stream of gas flowing across the direction of motion of the flat stock. The gas and atomized liquid caused by the gas is removed from the chamber through an exhaust port connection located opposite from the flat stock.

Abstract: An ejector pump for the transport of materials or mixtures of materials capable of flowing with the aid of a fluid driving medium is provided. The ejector pump includes at least one flow management profile which is placed in the flow channel of the ejector pump and which displaces the fluid that is flowing against the profile in a lateral direction component away from the original direction of flow. Therefore, the fluid in the middle of the flow channel makes its way closer to one of the flow channel walls thus limiting the areas of turbulence that occur during the mixing of material that is to be transported with the driving medium.

The pump includes at least one suction chamber per pump stage, each suction chamber being connected to a common antechamber with the intake of the materials at one end and the flow channel on the other. The flow channel is circular in shape and constructed for radially outward directed flow. The wall elements of the flow channel are comprised of ejector rings located concentrically to each other, adjacent ejector rings forming a passage for the materials between each suction chamber and the flow channel.
