Title DR-1 RUBBER LEVEL CROSSING<br />
Authors SLOBODAN RAJIĆ<br />
Institution TELECOR ZAGREB, Croatia<br />
Patent no. Pending<br />
The Dr-1 Rubber Level Crossing is a system installed on<br />
railway crossings where the track intersects with the<br />
asphalt road at the same level. Its task is dual: to ensure a<br />

Title ELECTROMAGNETIC ELEVATOR<br />
Authors Anton Bačić, Ružica Kamenjašević<br />
Institution Srednja škola za elektrotehniku i računalstvo, Croatia<br />
Patent no. Pending<br />
The principle of work is based on electromagnetic<br />
induction, and the elevator is on steel guideways. The<br />
complete circuit consists of 16 coils with the central iron<br />
core which function as magnets.<br />
Description This elevator works with the repulsion force of magnets of<br />
different poles. The flow of current through the coils<br />
causes the iron cores to behave as electromagnets, as they<br />
are polarized so that the north pole faces the elevator and<br />
the repulsion force of the same poles pushes the elevator<br />
up. Considering that the elevator is on the coils it can not<br />
