The invention relates to a thermal time relay, based on the<br />
principle of the operation of thermometric relays. Time<br />
relay is consists of an elastic element which communicates<br />
with a brass tank which is in contact with a heat source.<br />
Elastic element of the relay, according to invention, is<br />
constituted of a brass tube with the elliptical section,<br />
modeled after contour of a flat spiral and is filled with the<br />
Description<br />
mercury, this communicating at the bottom with a brass<br />
container also filled with mercury, that it is under the heat<br />
action generated by a Peltier battery. Under heat action<br />
received at the Peltier battery, mercury content in the brass<br />
tube and from the tank, it distend provoking the<br />
deformation of the brass tube, which by means of some<br />
auxiliary system, determine, after a preset time, closing an<br />
electrical contact.<br />

Patent no. Patent application No. A/00455 din 25.05.2010<br />
The invention relates to an experimental method which<br />
completes the assembly of the theoretical methods used<br />
for numeric solving of the electromagnetic field problems:<br />
finite difference method, finite element method, boundary<br />
Description element method. The method is applied in the case of<br />
rotating machines and it is based on the utilization of a<br />
ferrofluid, over which some gold leaf powder is spread.<br />
The analysis of gold particles’ movement is studied using<br />
the technique “of the moved images” and numeric<br />
photographic camera..<br />
