  • Patent number: 10294153
    Abstract: Methods of formulating, premixed cement-based tiling compositions and application of such premixed cement-based tiling compositions as an adhesive or grout. The premixed cement-based tiling compositions include a premixed cementitious formulation having a pH and an alkali activation constituent. The premixed cementitious formulation includes an aluminous or a calcium aluminate cement slurry in an amount of about 35 wt. % to 50 wt. % in combination with one or more filler or modifier materials present in an amount of about 40 wt. % to 65 wt. %. The alkali activation constituent destabilizes the premixed cementitious formulation by increasing the pH thereof to generate a reaction between the premixed cementitious formulation and the alkali activation constituent resulting in the cement-based tiling composition for use as an adhesive or a grout. The alkali composition may be sodium hydroxide supersaturated with lithium carbonate.

  • Patent number: 9920807
    Abstract: The invention relates to a friction lining carrier plate (1), which has a metal sheet, to a friction lining, to a friction lining receptacle and to a brake. The metal sheet is formed in such a manner that it has a first and second recess (11, 20) on the friction lining side, wherein the metal sheet has at least a second recess (20) on the friction lining side, wherein the first and second recesses (11, 20) have a differing depth. The first and second recesses on the friction lining side are each formed as an elevation on the side of the actuation means.
