Abstract: Polyol-polycarbonates having a molecular weight comprised within the range of from 750 to 2500, endowed with good rheologic characteristics and having a low glass transition temperature (Tg), are obtained by means of the reaction, under transesterification conditions, of     (a) an organic carbonate;   (b) a saturated alifatic  alpha , omega -glycol; and   (c) tris-(hydroxyethyl)-isocyanurate.   These polyol-polycarbonates are useful as bases for paints in combination with polyisocyanates. Furthermore, the polyol-polycarbonates can be reacted with bicarboxy acids, or with cyclic anhydrides in order to yield the corresponding products with carboxy end groups which are useful as bases for paints in combination with melaminic or epoxy resins.

Granted: 1988-11-30
Abstract: Character contours are broken down into a series of orthogonal vectors. Pixel drop out occurs where opposite going vectors coincide. The inside pixel (410 or 440) of each vector (400 or 430) is set to the vector length if the length is greater than the set values of the inside and the outside (420,450) pixels. This procedure is repeated for all the vectors for all the contours. At completion all those pixels set to one or more are set on to produce a drop out corrected bit map which is logically OR'd with the original drop out containing bit map.
