Abstract: A device is provided for extracting water from atmospheric air (8) having a free-flowing adsorbent or absorbent (3, 13), in particular a saline solution (3), having a hygroscopic salt for the adsorption or absorption of water, the adsorption or absorption being provided at least along an adsorption or absorption section (7), which realizes a high yield of (potable) water per unit volume of the structure or of the absorbent/adsorbent (3), a decrease in the assembly effort and a stabilization of the process. This is achieved according to the invention in having a free-flowing adsorbent (3, 13) or absorbent (3, 13) disposed at least along the adsorption or absorption section (7) essentially on a guide element (1, 16, 19, 22, 24) for guiding the adsorbent (3) or absorbent (3), in particular on a presettable track.

Abstract: The invention relates to a lifting device, especially a lift or a lifting platform, comprising a displacement unit (1, 6, 7, 8) for at least partially displacing a load in a vertical manner. The displacement device (1, 6, 7, 8) comprises at least one first drive motor (1) comprising a first motor shaft (3) and especially a second drive motor (1) comprising a second drive shaft (3), in addition to one first brake unit (2) arranged on a first brake shaft (3) and a second brake unit (2) arranged on a second brake shaft (3), in addition to at least one first drive element (7) which can be rotated about a first drive shaft (6) in order to drive at least one first traction element (8) which is subject to tension and a second drive element (7) which can be rotated about a second drive shaft (6) in order to drive at least one second traction element (8) which is subjected to the effect of tension.

Abstract: Equipment for temporarily coupling an elevator car door leaf with a shaft door leaf and for actuating a car door lock includes a coupling mechanism arranged at the car door leaf with two entraining runners mounted on two pivotable adjusting elements. The spacing between the entraining runners can be adjusted by pivoting of the adjusting elements between an uncoupling setting and a coupling setting, wherein the entraining runners in the coupling setting co-operate with at least one coupling element mounted at the shaft door leaf. One of the entraining runners is coupled by way of a respective articulation member with one arm of each of the two adjusting elements, wherein a contact force arising between the entraining runner and the corresponding coupling element in the coupling setting causes the entraining runner to execute an additional movement which is guided by the articulation members to unlock the car door lock.

Abstract: An elevator door drive device, which opens and closes at least one car door leaf and a corresponding shaft door leaf, includes a coupling mechanism mounted at the car door leaf for transmitting the car door leaf movement to the shaft door leaf with two parallel entraining runners mounted on pivotable adjusting elements. The spacing between the runners is adjustable and a drive unit transmits closing and opening movements to the car door leaf by way of a drive apparatus that leads the entraining runners to a coupling element at the shaft door leaf before the start of the opening movement and moves them away from the coupling element after the end of the closing movement. The pivotable adjusting elements, during opening or closing the door leaf are blocked by means of a catch acting in both pivot directions.

Abstract: A lift door panel which, apart from a good sound and vibration damping with a high degree of rigidity, is producible to be largely distortion-free, wherein a warping in the case of fire and under high heat effect is reduced or avoided. The door panel has a front and back wall which are connected together by a first connection which is releasable under the action of heat and has at least a second heat-resistant connection.
