  • Publication number: 20260327876
    Abstract: A textile arrangement for irrigating a flat roof planting has a first textile on a first spacer block. The first textile extends downwards at least on one end face of the first spacer block in order to be able to draw up accumulated water on a flat roof by capillary force. The first textile is particularly absorbent because it has cross-linked microfilaments which in cross-section have the shape of a pizza with multiple pizza slices, or are star-shaped in cross-section. The microfilaments can be at least partially welded together. Preferably, a substrate for growing a plant is piled up directly on the first textile. In a further preferred embodiment, multiple spacer blocks are each provided with a textile described herein, preferably the same textile, and are connected to each other to form a large-area, in particular, gap-free, assembly.

  • Publication number: 20260324570
    Abstract: A textile arrangement for a flat roof provides both a base for continuous irrigation for a planting and a secure fastening for an object being a photovoltaic module. The textile arrangement has a first spacer block connected directly to a second spacer block. On the first spacer block a first textile absorbent is arranged. On the second spacer block the first textile and/or a second textile absorbent is arranged. On the first spacer block, a first holder is screwed in, with which a mounting element of the object is attached to the first spacer block. A plurality of spacer blocks are connected to each other by block connecting means forming a very difficult to lift composite. A substrate can be directly heaped on the first textile and the second textile. The first textile and the second textile extend downwards in portions to irrigate the substrate with accumulated water.

  • Publication number: 20090205904
    Abstract: A System as attachment possibility for safety equipments to arrest falls produced by attachment points or, respectively, guide lines or rails secured by a weighting load, is designed so that a disk with a large area of adaptable size and form is composed of individual elements with a small area which are designed to be connected together. Said disk is arranged to be covered with a weighting load (as for example a bulk material, plates or the like) and is accordingly able to take up forces as occur in the case of arresting a fall by way of attachment points applied to it or integrated in individual elements.

  • Patent number: 7316456
    Abstract: In a roadheading or mining machine including cutting tools movable over the mine face and roof bolt drilling and setting devices, at least two roof bolt drilling and setting devices are pivotally connected with the machine laterally outside the longitudinal central plane of the machine. The roof bolt drilling and setting devices are pivotally supported on a bolting platform capable of being displaced in the longitudinal direction of the machine, or on an element connected with the bolting platform.
