Burning is the oldest technology of humanity, and it has been used for more than a million years.Combustion plants must be as efficient, to achieve a more complete combustion, to have a higher efficiency and an emission ...

Applications of sound and ultrasound air-jet stem generators became of great interest in heat and power engineering, in environmental protection, in the production of heat insulating material, extraction of poor uranium ...

The chargers on tire with direction through side-slip are equipments for used loading different materials, having very good manoeuvrability in narrow places due to the possibility of turning around their centre of weight. ...

This paper deals with practical insulation devices, systems to provide the tradeoff between the contact with earth (in order to resist to gravitation) and the separation from earth (in order to withstand the earthquake). ...

The specific innovative device presented in this paperwork is a hydraulic system operating with viscous fluid that provides damping for shocks and vibrations. A basic viscous fluid device is constructed on the principle ...

Special systems capable to ensure a proper isolation for building structures against dynamic actions have experienced a continuous development in the recent years. These systems are designed to provide increased safety for ...

This paper presents some aspects related to the way the cushioning capacity of hydraulic cylinder is affected by the temperature variations of the hydraulic fluid. We have analysed the case of the hydraulic cylinders with ...

the description of the kinematics of mechanisms driven by hydraulic cylinders, hydraulic agent is usually considered incompressible. This computing hypothesis introduces errors which, in certain situations, can not be ...
