    摘要: By the process of the present invention the activity of heterogeneous catalysts for reactions at normal and low pressures is restored or maintained. These catalysts can lose their activity as a result of the deposition, physisorption or chemisorption of organic or inorganic deactivating substances which are carried over into the reaction system or are formed as the result of side reactions in a chemical synthesis carried out with the aid of the catalyst. The activity is restored or maintained by using a pressure greater than the critical pressure of the fluid phase and a temperature higher than or equal to the critical temperature of the fluid phase. In this process, the pressure and temperature are applied for a period such that the deactivating substances are either removed from the catalyst or are not initially deposited thereon or absorbed or formed.

    摘要: The invention concerns an arrangement for the adjustment of the position of a shearbar with respect to knives of a chopper assembly. The arrangement includes a first adjusting drive to position the first end of the shearbar at a predetermined first spacing from the knives and a second adjusting drive to position the second end of the shearbar with respect to the knives until a spacing measurement arrangement indicates that the spacing between the shearbar and the knives is less than a threshold value. An analogous procedure is applied to the first adjusting drive. On the basis of the measurement values the shearbar is brought into a position that corresponds to a desired gap between the shearbar and the knives. Each of the first spacing and the second spacing are greater than the desired gap between the shearbar and the knives.

    摘要: A forage harvester chopper arrangement is located within a housing provided with an access door mounted for pivoting vertically between a chopping position, wherein access to the chopping arrangement is prevented, and a grinding position, permitting access to the chopping arrangement by a grinding arrangement. A locking arrangement is associated with the access door and an actuator is coupled to the access door and the locking arrangement by a linkage containing lost-motion means which operates such that when moving the access door to its grinding position, the locking arrangement is moved to its unlocked position prior to the access door being raised to its grinding position, and such that when returning the access door to its chopping position, the access door is closed before the locking arrangement is moved to its locked position.

    摘要: A device for the building up and discharge of an annular dump of bulk on a circular storage site. In the center of the circular storage site is provided at least one jib of a dumping device rotatable about a vertical axis, which is fed with the bulk material by means of a feed belt, the discharge end of which is situated above the dumping device in the center of the device. Moreover there is provided at least one removal device which can be swivelled about said vertical axis and machinery situated in the neighborhood of the center by means of which the bulk material removed is fed to a conveyor belt passing through said vertical axis. The removal device and the jib of the dumping device are arranged on a framework which is supported and guided on at least one circular railway concentric with said axis.
