cutter knife case that is fastened to the ruler surface. The<br />
bracket is tall enough to support the whole ruler avoiding<br />
books from falling out of the whole. This certainly is an idea<br />

Patent no. Patent application No. A/00847/17.09.2010<br />
The patent consists in a method to achieve a uniform nickel<br />
layer by electroplating of a copper or a coppery iron support<br />
in the presence of polyvinylpyrrolidone, used in mechanical<br />
engineering as active surface agent.The method for uniform<br />
nickel electroplating of a copper or a coppery iron support is<br />
characterized by use of Watts baths to achieve thin<br />
Description<br />
passivated layers. Furthermore, it uses NiSO4 . 6H2O - 240 g/L<br />
and NiCl2 . 6H2O – 45 g/L acid solutions, 30 g/L boric acid as<br />
buffer system and 5 g/L polyvinylpyrrolidone as active<br />
surface agent, with the average temperature range between<br />
50-65°C and the current densities range between 300 – 500<br />
mA.<br />
