Abstract:
The invention concerns a coating composition capable of being cold vulcanised (EVF), characterised in that it comprises, in a mixture: (1) at least one polyorganosiloxane having, per molecule, at least two C2-C6 alkenyl groups bound to silicon; (2) at least one polyorganosiloxane having, per molecule, at least two hydrogen atoms bound to silicon; (3) a catalytically effective amount of at least one catalyst, consisting of at least one metal belonging to the platinum group; (4) an adherence promoter; (5) optionally a reinforcing system which can be at least a polyorganosiloxane resin and/or a reinforcing filler; (6) optionally at least one cross-linkage inhibitor; (7) and mineral or organic hollow microspheres.
Abstract:
A method and apparatus are disclosed for reducing graphic patterns, coded by binary characters and represented in rows and columns of a prescribed grid, by purely electronic techniques. The reduction occurs by decrement of the binary characters. First, the binary characters representing the rows and, subsequently, the binary characters representing the columns are decremented in accordance with the desired reduction ratio. In the decrement of the binary characters, it is seen that the structure of the graphic patterns is retained to as great an extent as possible.
