PCT/RO2014/000021IONESCU, IuliuIONESCU, Iuliu
The utility model consists of an electricity generator with drinking water, discharging oxygen and hydrogen based on the differential electronegativity phenomenon of chemical elements, which uses drinkable water to transfer the electrical loads. The novelty lies in the fact that by using electrodes having particular physical structures, made of different materials and adding a condenser, an alternative impulse generator and a doubler or a voltage multiplier useful, stronger power is achieved. In this process, water electrolysis takes place concomitantly, gas bubbles appearing in the two electrodes. As we know, oxygen is discharged to the anode, in the case in point, the aluminium electrode, and hydrogen to the cathode, in our case the copper electrode. In a larger generator, these gases may be collected and used to produce heat energy or in industry, agriculture, medicine etc. It can be used in any field of industry, agriculture, medicine, household etc.

The invention refers to a process for rapid manufacturing that uses a focused ultrasound beam according to the invention. The process is based on the local ultrasound welding of the material (2) grains that is under a powder form, welding that takes place solely in the focal spot of the focused ultrasound beam, the focal spot being scanned across the X-Y-Z directions within the powder (2) bed so as to 3D build the entire object (7) that is desired. The processes taking place in the focal spot region are local melting, local melting due to friction followed by filling of the gaps existing between grains, removal of the grain asperities, local inter-diffusion between neighboring grains as well as other phenomena that take place at the interfaces between materials when these are subjected to an ultrasound field.

Described systems and methods allow protecting a computer system from malware such as viruses, Trojans, and spyware. For each of a plurality of executable entities (such as processes and threads executing on the computer system), a scoring engine records a plurality of evaluation scores, each score determined according to a distinct evaluation criterion. Every time an entity satisfies an evaluation criterion (e.g, performs an action), the respective score of the entity is updated. Updating a score of an entity may trigger score updates of entities related to the respective entity, even when the related entities are terminated, i.e., no longer active. Related entities include, among others, a parent of the respective entity, and/or an entity injecting code into the respective entity. The scoring engine determines whether an entity is malicious according to the plurality of evaluation scores of the respective entity.

9. WO/2015/041555 PROCESS AND INSTALLATION FOR PRODUCTION OF SYNTHESIS GASWO26.03.2015
C01B 3/24
PCT/RO2014/000026CELAC, VasileCELAC, Vasile
The process and the installation for production of synthesis gas is a multi phased method of obtaining synthesis gas (to be referred from now on as syngas) in a continuous flow; the purpose of this gas is using it as an alternative fuel. This process consists of creating, by aid of an injector (3), a continuous flow of a mixture between water and a liquid classical fossil fuel. The liquid mixture is fed into a "rotating cavitation/vaporization device" (6) and is transformed into a continuous flow of a gaseous mixture. The gaseous mixture is further more, successively super-heated: at first in the cylindrical/toroidal (19) part of the double mantle/shell of a horizontal cylindrical furnace (25); the mixture is secondly super-heated in a reforming tube (12), placed inside the burning area (24) of the furnace. The cylindrical furnace (25) is coupled to the lid (17) of a "user boiler" (18) so as to facilitate the practical use of the hot gases resulting from the furnace burning area (24) of the cylindrical furnace (25). As a result, from the successive chemical processes of pyrolysis and of the non- catalytic reforming with steam at high temperatures of the hydrocarbon from the mixture, the syngas is produced. The syngas is then fed into a dualburner (11), replacing the consumption of classic fossil fuels. The classic fossil fuels are initially used to pre-heat the furnace, facilitating the temperatures necessary for the formation of syngas. The heat generated from the ignition and burning of syngas is used to maintain, in the cylindrical furnace (25), the temperatures necessary for the endothermic thermo chemical reactions that sustain the continuous flow of syngas. The heat resulting from the burning of syngas is also used to cogenerate thermal, electrical or/and mechanical energy.
