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

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