Abstract: A pair of axially spaced combustion chambers are provided and a common ratchet or control mechanism is positioned between the spaced combustion chambers. A pair of vanes are mounted in each combustion chamber, with the vanes mounted in each combustion chamber, with the vanes mounted on concentric shafts and free to rotate relative to each other. The ratchet mechanism positioned between the combustion chambers functions to resist counterclockwise movement of the vanes in one combustion chamber, while allowing free clockwise movement and to resist clockwise movement of the vanes in the other combustion chamber while allowing free counterclockwise movement. The reaction forces generated in the ratchet mechanism from the two combustion chambers thus tend to cancel each other out. The central ratchet mechanism includes a housing which absorbs the reaction forces from both combusiton chambers, which is free to rotate in the event that the reaction forces generated in the two combustion chambers become unbalanced.

Abstract: Process for producing a nitric acid of a concentration from 75 to 99.9% from a more diluted nitric acid, wherein a nitric acid of a concentration of about 45 to 70% is rectified in contact with a liquid extraction medium to prevent the formation of a nitric acid-water-azeotropic mixture, and the vapors of the concentrated nitric acid are condensed and a concentrated nitric acid is obtained and wherein additionally the extraction medium is reconstituted through reconcentration and returned into the extractive rectification, wherein the nitric acid to be concentrated is fed as a boiling liquid or partially vaporized to the extractive rectification preferably carried out in two columns (K 1.0 , K 1.1 ), by utilizing the amounts of heat available to the entire process (W 1 , W 2 , W 5 ), wherein, before feeding into the extractive rectification nitric acid is added to the extraction medium, and the energy required for the extractive rectification is supplied through indirect heating (W 4 , W 8 ) and the extraction medium supplied in most concentrated form to the extractive rectification, so that simultaneously at the greatest possible dilution of the extraction medium flowing from the extractive rectification, the circulation amount of extraction medium is minimized and the utilization of energy maximized.

Abstract: The invention relates to a device and method for the drying of damp products, in particular, pasta. According to the invention, the product to be dried in a dryer, is placed in an inner chamber and humid warm air is circulated around the product, in order to ensure a gentle drying thereof. Dry hot air flows in an outer chamber, enclosing the inner chamber, which prevents condensation of water forming in the outer chamber. The inner shell has essentially no heat insulation as the external shell has a conventional heat insulation from the outside air. The dryer construction with a double shell prevents damp from entering the insulation material of the insulating layer through the inner shell and thus forming heat bridges, despite incomplete sealing of the inner chamber.

Abstract: A cable conveyance having a storage region for garaging the carriers which can be decoupled from the transport cable. The carriers are displaced along a transport rail to the storage regions by a reversible drive and are permitted to move by gravity along storage rails into this region or by positively tilting these storage rails back to the transport rail to return to the cable. Thus within the storage region the displacement of the carriers is by gravity only and there is no need to provide a special drive for entrainment of the carriers along the storage rails.
