Abstract: The invention relates to a device for increasing the degree of dynamic adaptability of the powered props in coal mine working, and which comprises a control unit (A) and a processing unit (B), namely two auxiliary valves, an inlet valve (12) and a direction valve (11). The device ensures the working in geomechanical conditions wherein the mine stress field appears as fall of country, with high loading rate and a force of impact of more than 10^4 joules. By using said device, the hydraulic props are protected against the excessive rise of the liquid pressure in the chamber of the cylinder prop eliminating the possibility of mechanical damages, human and technical accidents. The device works in quasi-statistical conditions, as a common protection valve, or in dynamic conditions when a pusher (4) ensures the opening of the pilot valve (5) at low pressure values, but at high variation speeds thereof so that the piloted valve receives the stress impact as a direction valve with a slack spring. When the stress in the hydraulic props (1) decreases, the spring of the pilot valve (5) closes the return and when the cavity at the back of the piloted valve is filled with fluid, the pressure in the prop causes the piloted valve to close. In dynamic conditions, the pressure impact controls the pilot valve opening, before the pressure increase at the back of the piloted valve. The invention may be used for equipping the hydraulic props provided in the sustaining sections, which are to work in the working whose roof is characterised by fall of country.

Inventor: JELAVIC IVAN
IPC: G09F3/03
Filed: 1998-09-14
Abstract: The invention relates to an ecoded safety seal with coating, used for protecting various objects against unauthorized access. According to the invention, the safety seal comprises a "mother" part (2), the thread (10), the "father" part (4), having the body (12) showing the longitudinal channells (24 and 26) and (28 and 30), connected through the passing channel (18) situated at the base of the "father" part (4), the "father" part (4) having an opening (22) in the center of the body (12), through which the both longitudinal channells (24 and 26) and (28 and 30) are connected in center, the protective coating (6) of the "father" part (4) showing, at the upper part, an orifice (20) wherein there meet both longitudinal channells (24 and 26) and (28 and 30)
Patent RO-125465-B1 (RO)
Title: Wind turbine rotor
Inventor: VIŞA ION
IPC: B60B1/00
Filed: 2008-11-17
Abstract: The invention relates to a rotor for a wind turbine of relatively reduced weight, complexity and gauge, which operates at relatively low wind velocity, of less than 4 m/s. According to the invention, the rotor comprises a hub (1) and a hoop (2) with streamlined profile which are rigidly connected to each other by means of some resistance spokes (3) between which some V-shaped blade-holding spokes (4) are equiangularly placed, with some tips fixed in some holes of a medial disc integral with the hub (1) and some ends fixed in the hoop (2) under a certain inclination angle, on which some trapezium-shaped flat blades (5) made of light materials are fixed.
Patent RO-126155-B1 (RO)
Title: Simulator determining optimum parameters of containers for transportation of aquatic animals
Inventor: OPRINA GABRIELA
IPC: A01K97/04
Filed: 2010-10-14
Abstract: The invention relates to a simulator determining the optimal parameters of the containers for the transportation of aquatic animals, being meant to make the correlation between the density and amount of biological material (kg of fish/mof water), the water aeration level, the transportation container volume and the aerator characteristics. According to the invention, the simulator consists of a container (1) made of acrylic glass for ensuring the visualization of the aeration phenomenon, an aerator (2) consisting of a circular plate with equally spaced orifices, an air pump (3) which ensures supply of the aerator (2) whose flow rate is read and controlled by means of a rotameter (4), a pipe (5) for sampling water that is being aerated, which by means of a peristaltic pump (6) is led to the measuring cell of an oximeter (7), provided with oxygen and temperature sensor and with display for displaying these parameters and then reintroduced into the container through the nozzle of a valve (8), the container aeration as well as changing the pressure on the free surface being ensured by means of a valve (9).
Patent RO-128634-B1 (RO)
Title: Optical biochip for warning on pork and beef spoilage
Inventor: AMARIEI SONIA
IPC: G01N27/327
Filed: 2011-05-04
Abstract: The present invention relates to an optical biochip for warning on the pork and beef spoilage, for optically warning the consumers on the meat spoilage, consisting of a disposable biosensorial disk (D), located on the interior wall of a vacuumed polymeric packing (2) in which the meat (1) is packed, said disk having a red colour reaction with the ammonia in the ammoniacal water, which is the specific product in meat spoilage. According to the invention, the biosensorial disk (D) consists of a submicrometric insoluble and non-toxic powder (3) of titan dioxide, having the role of catalyst and support matrix, where there are mixed a fine non-toxic powder (4) of silver chloride, a semi-permeable polymeric membrane (6), attached by thermal welding onto the disk (D), on the interior wall of the bag (1).
