Applying a glossy colour coating on an article involves: (a) providing a coloured surface on a substrate, (b) vacuum depositing a metal on the substrate to form discrete islands up to 100 Angstroms thick, (c) dissolving with a solvent residual metal that has been deposited in the spaces between the islands to enlarge the spaces through which the coloured surface is visible, (d) applying a clear li...

Bioreactive material of the glass or partially crystallised glass type for a bone prosthesis or dental implant, welding by chemical bonding with a bony tissue, this bond not presenting ossification defects and having at the same time a small thickness and a greatly improved mechanical strength, the said material having a low expansion coefficient and a very good adhesiveness to structural material...

A method for the separation of magnesium hydroxide from a mixture of particulate magnesium hydroxide and dissolved sodium sulphate in water and for the washing and thickening of the magnesium hydroxide, includes the steps of pumping the mixture from a holding tank 14 through an ultrafiltration module comprising two banks 16, 18 of tubular membranes to which is applied a back pressure so that the d...

The present invention relates to organopolysiloxane-containing compositions which are self-dispersing in water, their preparation and their use. The compositions of the present invention are suitable for all uses where organosilicon compounds, especially in water-diluted form, can be employed. Such uses include uses as water repellant agents on building materials.
