Abstract: With a device for influencing the flow, particularly in a horizontal connecting pipe (1) between a coal gasification reactor and a gas cooler/purifier, a solution is supposed to be created, whose task consists in being able to reduce or shut off the gas stream of a hot synthesis gas, if necessary, without being exposed to the great stresses caused by the corrosiveness and the high temperatures, while avoiding complicated valves or regulation devices. This is achieved by means of a Venturi constriction in the flow path of the gas in the pipe (1), as well as a flow cone (4a) positioned on a push rod (4) that is disposed centrally, whereby a connecting rod system (4b) that is guided to the outside is provided to move the push rod (4), whereby the connecting rod system (4b) that moves the push rod (4) is formed by a connecting rod arm guided in a dummy connector and a connecting rod arm guided out of the dummy connector (8) by way of a packed gland (6).

Abstract: There is provided apparatus for treating water containing industrial waste products. A first tank contains water at a determined pressure. A second tank is placed inside the first tank and communicated with a lower portion thereof. It contains water at a lower pressure than that of the first tank. An inlet device of the discharge product is located in the second tank. A first dilution sector of the waste product is external to the tanks but in communication with the second tank at one end and connected to the other end with a Venturi tube and has an outlet duct for waste product diluted by said second tank. The Venturi tube is in communication with the first tank and creates a depression of the second tank with respect to the first tank. The second tank has an internal portion for the dilution of the industrial waste product.

Abstract: The present invention refers to a water apparatus for treating industrial waste products comprising a first tank (2) containing water at a determined pressure, a second tank (4) placed inside the first tank and with which it is in communication in the lower part and which contains water at a lower pressure than that of the first tank (2), an inlet device (6, 7) of the discharge product in the second tank (4), a first dilution sector (14) of the waste product which is external to the tanks (2, 4) but in communication with the second tank (4) at one end (15) and connected to the other end with a Venturi tube (17), an outlet duct (18) of the waste product diluted by said second tank (4). The Venturi tube (17) is in communication with the first tank (2) and is suitable to create the depression of the second tank (4) with respect to the first tank (2). The second tank (4) comprises internally a further sector (10) for the dilution of the industrial waste product.

Abstract: A device for improving the quality of indoor air comprising a casing (2) with an air inlet (3) and an air outlet (5), a member (7) arranged to cause air in a room, in which the casing is placed, to flow in through the inlet and inside the casing to the outlet and therefrom out into the room again, and leaf surfaces and water nozzles (9, 11) adapted to influence the quality of the air passing through the casing. The casing also contains leaf plants (9) and the member (7) is provided in order to cause the air to flow past the leaf surfaces of the plants in order to remove contaminations and particles from the air by absorption thereof by the leaves of the plants.
