Inventor: WALTER HUMMEL
IPC: B01D53/18
Filed: 1979-11-01
Abstract: A device for separating impurities from gases by means of a washing liquid. The device includes three (3) interconnected chambers: a suction chamber, a mixing chamber and a separating chamber, wherein the outer wall of the mixing chamber is the inner wall of the suction chamber and the inner wall of the mixing chamber is the outer wall of the separating chamber. In the upper portion of the mixing chamber there is an inlet which connects the suction and mixing chambers for conveying contaminated gases rising in the suction chamber downwardly into the mixing chamber. In the upper portion of the mixing chamber below the outlet there is mounted a plurality of spray nozzles for downwardly spraying washing liquids which removes impurities in the contaminated gases as they flow downwardly through the mixing chamber. At the bottom of and directly open to the mixing and separating chambers is a liquid collection chamber for collecting used washing liquids and impurities from the gases. In the inner wall of the mixing chamber above the collection chamber is an outlet which conveys the washed gases from the mixing chamber upwardly into the separating chamber. The separator in the separating chamber removes remaining droplets of liquid from the washed gases before the washed gases pass into the surrounding atmosphere. Within an outer wall of the suction chamber there is an exhaust opening which is normally closed. When the device is operating properly the opening remains closed so that the contaminated gases will pass from the suction chamber to the mixing chamber. When there is a breakdown, however, the opening is opened so that the contaminating gases are exhausted from the device without passing therethrough.

Abstract: The invention relates to a fifth-wheel coupling with a coupling plate which has an insertion slot through which a kingpin can be inserted. The fifth-wheel coupling furthermore has a first and a second fastening part which surround a kingpin. In this arrangement, the kingpin (5) rests snugly in the first fastening part. Since the driving operation causes high wear on the kingpin or on the fastening part readjustment is often necessary in order to compensate for a clearance produced by the wear between kingpin and fastening part. To this end, an eccentric insert is provided which is arranged around the pivot of one fastening part. The insert has a lever-shaped extension (9a), with the aid of which the insert (9) can be rotated. If the lever (9a) is rotated the fastening part moves and entrains the second fastening part at the point of mutual engagement. This adjustment makes it possible for the kingpin (5) to be brought into close contact with the first fastening part so that the clearance produced by wear is compensated for. The proposed arrangement makes precise adjustment or readjustment possible and is easily accessible from the outside. By virtue of the simple construction expenditure on servicing and operation are insignificant. <IMAGE>
