A penetrating base oil emulsion and a method of using the penetrating base oil emulsion to fill voids below the surface of an asphalt pavement. The penetrating emulation further being water resistant so as not to be washed off a pavement surface by water after being applied to the pavement. The penetrating base oil emulsion can also rejuvenate the surface of the asphalt.

A method and apparatus (1) for treating a filter (2) for filtering particulate matter from exhaust gas. A reservoir (3) containing a dry powder (4) is provided. A vacuum generator (6) establishes a primary gas flow through a porous structure of the filter (2) by applying a pressure reduction to an outlet face of the filter (2). A spray device (7) receives the dry powder (4) from a transport device (8) and sprays the dry powder (4) towards the inlet face of the filter (2). A controller (9) is configured to control operation of at least the vacuum generator (6) and the spray device (7).

A process for manufacturing a part made of a ceramic matrix composite material, includes coating an outer surface of a porous preform with a layer of a fugitive material to form a model of the part to be obtained, the fugitive material being wax or resin, the fugitive material layer in the model not exceeding the highest peak of surface undulations of the preform, and ceramic and/or carbon particles being present in the porosity of the preform, coating the model formed with a ceramic powder composition, heat treating the coated model to remove the fugitive material and form a ceramic shell mold by sintering of the ceramic powder composition, introducing a molten composition including silicon into the shell mold to obtain the part in the shell mold, the molten composition infiltrating the porosity of the preform to form the ceramic matrix, and separating the shell mold from the part obtained.

The invention relates to a dental ceramic blank, in particular a filled milling blank, comprising at least one organic Compound, such as a polymer polymerized in the blank, for improving the machining properties of the blank. The blank has an open-pore ceramic microstructure which has 2 to 50 wt. %, based on the total composition of the dental ceramic blank, of at least one organic Compound. The invention also relates to a method for producing the blank. The milling blank according to the invention clearly exhibits improved material properties compared to unfilled purely ceramic milling blanks which have been milled into blanks for molded prosthetic parts in CAD/CAM methods
