The third leg is sized to extend through an aperture in the web of the main runner and then be bent to lie alongside the web of the main runner on a side opposite to that of the second leg.

Abstract: A melt for use in the production of man-made vitreous fibres may be formed in a circulating combustion chamber (20) by melting particulate material. The material is collected in a base region of the combustion chamber (26), where it can be heated using submerged heating means (40). The submerged heating increases the homogeneity of the melt within the melt pool (30), the coherence of which is maintained by the use of a siphon (50) to extract melt from the combustion chamber.

The supply of water and nutrients by the at least one irrigation device is controlled by the control means in dependence on the monitored water and/or nutrient levels. In this manner, the water and nutrient levels of the substrates can be accurately controlled.

Abstract: The invention relates to a heat insulation element for insulating building facades, in particular for heat insulation composite systems, composed of a heat insulating board and a reinforcement mesh that can be penetrated by fastening elements, in particular plugs, wherein the reinforcement mesh is placed in the area of a large surface of the heat insulating board. It is the object of the invention to avoid the disadvantages of the state of the art and in particular to provide a heat insulation element which even in case of high tightening torques of the fastening elements does not excessively tends to be deformed into the direction of the building facade. This aim is achieved by a heat insulation element according to the invention, in which the reinforcement mesh is arranged as a component of an abutment at a distance to the surface of the heat insulating board and in which the reinforcement mesh comprises a surface area which is smaller than the area of the surface of the heat insulating board.

Abstract: A building facade consisting of a building wall, an insulating layer comprising insulating elements, having a surface and disposed on the building wall, a facade cladding which is disposed at a distance from the building wall and from the insulating layer to form a rearventilation gap between insulating layer and facade cladding and a lock element provided for fire protection, which is disposed between neighbouring insulating elements of the insulating layer. In order to further develop a building facade in such a manner that it can be manufactured simply and therefore cost-effectively without additional structural elements being provided, the invention proposes a generic building facade where the lock element is formed in one piece from fibre material, extends over the surface of the insulating layer in the direction of the facade cladding and exhibits a compressibility and/or flexibility aligned at least predominantly between building wall and facade cladding.

Abstract: A plant growth system is provided in which an irrigation device provides water and/or nutrients to a plant growth substrate. The plant growth substrate comprises an MMVF slab and a single MMVF block on a first surface of the MMVF slab. The MMVF slab comprises a drain hole which is disposed at one end of the surface, and the irrigation device provides water and/or nutrients to the substrate at a position more than 50% of the length of the slab away from the drain hole. This improves the control of water an nutrients in the slab as a whole.
