  • Patent number: 7128965
    Abstract: The present invention relates to a product, in particular a panel, that can be obtained by the Hatschek process and without autoclaving, and can be used as siding, cladding element or partition element, this product being formed from a fibre-reinforced cementitious matrix comprising at least one hydraulic binder, such as cement, at least one filler, such as calcium carbonate, and at least synthetic fibres. The invention also relates to a process for manufacturing the product.
    Type: Grant
    Filed: October 24, 2003

  • Patent number: 6875503
    Abstract: The present invention relates to a product in panel form, comprising a fiber-reinforced cementitious matrix, prepared from a sheet material by filtration on a screen of an aqueous suspension comprising at least one hydraulic binder, such as cement and at least one fibrous material and devoid of siliceous sand, thicknesses of said sheet material being superposed until the desired final thickness is obtained, in order to give a panel which is then autoclaved. The invention also relates to a process for manufacturing the product.

  • Patent number: 5183491
    Abstract: Disclosed is a material for a tempering process of glass plates utilizing a so-called contact process. It proposes a material with a base of an arrangement of thin metallic threads exhibiting a heat resistance on the order of 0.25.multidot.10.sup.-3 to 2.5.multidot.10.sup.-3 m.sup.2 .multidot.K.multidot.W.sup.-1 intended to be inserted between the cooling plates and the glass of a contact-tempering installation. The process makes it possible to temper glazings sufficiently so that they are used as automobile glazings and the durability of this thread-based material is compatible with an industrial usage.

  • Patent number: 4826522
    Abstract: The invention relates to the tempering of sheets of glass and optionally their bending by the so-called contact process. It proposes a process in which the edge stresses of the glass sheets are reinforced by cooling the edges of the glass sheets in relation to their central zone, particularly by blowing on these edges with a cooling gas. It also proposes a device to perform this preferred cooling of the edges, as well as glass sheets thus tempered. The invention applies to the production of glazings having nonfragile edges, particularly for the automobile.
