The invention relates to a cable-operated emergency switch (100) to be coupled to a cable (32) so that when the cable (32) moves along a movement path (41), an emergency switching signal can be triggered. Said cable-operated emergency switch comprises a coupling element (31) and a housing (29) with emergency switching triggering means (20) arranged therein and with an emergency switching element (22). The coupling element (31) is operatively connected to the emergency switching triggering means (20) so that the emergency switching element (22) can be switched to trigger the emergency switching signal my means of the movement of the emergency switching triggering means (20). The cable-operated emergency switch further comprises a warning switching triggering means (10) and a warning switching element (12), said warning switching triggering element being operatively connected to the warning switching element (12). A warning signal relating to the movement of the cable (32) can be triggered by means of the warning switching element (12) before the emergency switching signal is triggered.
The invention relates to a device (100) for preparing and spraying a construction material (10) for erecting a weather dam (1), and to a method for this purpose. The device (100) comprises a container (12) receivable on a vehicle (11), the device (100) having a conveying apparatus (13), by means of which the construction material (10) can be conveyed from the container (12) and can be transferred via a mixing arrangement (14) into a spray pipe (15), the mixing arrangement (14) being designed to add a liquid (16) to the construction material (10).
The present invention relates to a method for increasing the mechanical stability of potassium chloride compacted material, in which water is applied in an amount of 0.1 to 0.4 wt.% based on the mass of the newly produced potassium chloride compacted material onto the surface of the newly produced, still hot potassium chloride compacted material.
The invention relates to a method for producing sulphate of potash granulates, wherein 0.1 to 7.5 wt% of a sodium salt selected from among sodium chloride, sodium sulphate, sodium sulphate hydrates, sodium hydroxide and mixtures thereof are added to the sulphate of potash during the granulation process, the percentage by weight being in relation to the sulphate of potash used. In addition, 0.1 to 2.5 wt% of water are added prior to or during the granulation process. The invention also relates to the granulates obtained by said method as well as the use of sodium salts and glaserite and mixtures thereof for improving the mechanical properties of sulfate of potash granulates. The sulphate of potash granulates produced by the method of the invention have significantly greater bursting strength and significantly greater abrasion resistance than granulates known from the prior art.

The invention relates to a composition containing at least 80 wt.%, based on the total weight of the composition, of a magnesium sulfate/urea compound of the formula (I): [MgSO4 • m CO(NH2)2 • n H2O], where m ranges from 0.9 to 1.1 and n ranges from 2.1 to 3.1. The composition, based on the total weight of the composition, contains less than 10 wt.% of free MgSO4 in the form of anhydrate or in the form of urea-free hydrates of the magnesium sulfate, such as bitter salt or magnesium sulfate hexahydrate, and less than 10 wt.% of unbound urea. In particular, m in the formula (I) has the value of 1. In particular, n in the formula (I) has the value of 3. The invention also relates to the production of the compositions and to the use thereof as a fertilizer or a fertilizer additive.
The invention provides an additive for binding the residual moisture in the residue salt of a salt heap to reduce the heap water content, wherein the additive has hydraulically and/or pozzolanically setting properties.
