17-43 MULTIPLICATOARE DE FRECVENłĂ MECANICE

MECHANICAL FREQUENCY MULTIPLIER
This paper work relates to new and useful improvements in devices
that convert and transmit power. At this new type of transmission beyond the
problems that concern the stability of system another necessity is that of
frequency multiplication since the mechanism works as self-regulating geared.
Author of such type of transmission has provided a number of solution for this
problem. This paper work contein a relatively detalied analysis of the
phenomen of multiplication and study the main opportunity to achieve
multiplication.

20-86 GRUP COMBINAT DE ACŢIONARE PENTRU ROBOSCAN

COMBINED DRIVE SYSTEM FOR ROBOSCAN
This paper presents a new drive system for the award winning
ROBOSCAN, which is the only mobile Gamma scanner in the world. To ensure
the low speed high torque needed for the scanning process, a new drive
system needs to be implemented. The proposed solution is a new drive system
with a hydrostatic transmission for the work movement and a mechanical
transmission for driving between locations. Being a new system, testing was
done to define its characteristics. By doing this the testing methods were
perfected.
