Title: Paving stone or other paving block or paving slab
Inventor: PERMESANG CLAUS
IPC: E01C5/22
Filed: 1995-03-29
Abstract: Various  means  of  decorating  the  surface  of  concrete paving stones and paving slabs are known.   As an addi-tional technical decorating possibility it is proposed that a paving stone or other paving block or paving slab have an insert (1) made of a different material or merely having a different surface.  The inserts of the concrete stones or slabs otherwise produced by conventional means, consist for example of metal,  natural rock/  ceramics, glass, plastic, wood or even cork.  An example of an in-sert merely having a different surface would be one of ground or smoothed concrete, for example. This decorating technique, however, is also possible in paving blocks or slabs made of other materials such as ceramics or re-cycled plastic.  In any event, however, the possibilities for variation are put to use during the molding itself in the compression or casting mold,  for the creation of molded spaces for the insertion of the material with its decorative surface and/or contour.

Title: Ethylenically unsaturated compounds
Inventor: DRIVER MICHAEL JOHN
IPC: C07F9/09
Filed: 1994-11-23
Abstract: An improved process for producing ethylenically unsaturated phosphate ester compounds, especially 2-(methacryloyloxyethyl)-2' (trimethylammoniumethyl) phosphate, in a salt (HEMA-PC) comprises a two step reaction in the first of which a phosphalane reagent is reacted with a hydroxyl containing ethylenically unsaturated starting material, and in the second of which the intermediate formed in the first step is ring opened by reaction with trimethylamine to produce a zwitterionic product. In the process the two steps of the reaction are carried out in the same solvent with substantially no removal or addition of solvent after the first step. The solvent is preferably acetonitrile. The use of pure reagents avoids the production of undesirable by-products. The product is suitable for polymerising, for instance to provide cross-linked hydrogel copolymers used in ophthalmic applications.
