Measurement system for the identification and accurate determination of distorting loads in electrical networks and microgrids

The only measurement of distortion level in a network can highlight the need for action to control it. Among those actions is, for example, the use of power filters. However, the determination of the most suitable point where the filter must be connected and its most appropriate configuration requires further analysis of the micro-network (a subset of nodes in the network with different loads connected to each). Therefore, an additional study becomes necessary to establish the responsibility of each load in global distortion levels. In addition, the establishment of the model of the most responsible loads is also necessary in order to decide the filter configuration. In this sense, the load may be voltage distorting or current distorting. All this information is provided by the device of the invention. Indeed, the device, besides distributing the responsibility for overall levels of distortion between each agent, reports whether loads are voltage harmonics or current harmonic sources. This information is the most relevant to determining the power filter settings that best mitigate the distortion in each network node.

New device and system for the recovery of communication equipment

The present device is focused on the automatic recovery of operating systems for routers and switches, which is one of the fundamental claims on this invention since there are no current devices in the state-of-the-art for such purposes. Another particularity that distinguishes to the present invention is that it is not only software or hardware in contrast to other approaches, but of a complete hardware/software device (i.e, both capabilities are combined). Another of the most significant singularities is its portability, since the invention is based on a reduced size device (non rackable) and made up of autonomous battery. This allows to carry out any function with total freedom to move. Besides the comfort, it contributes a great improvement in working time, since operating with distant devices implies an additional time in turning off, turning on again, and enabling the necessary services to start the recovery procedure. As additional feature, the invention looks for the universality and independence from manufacturers or device model. Besides this purpose, another differentiated function is the capability to store the firmware of the communication devices to be recovered (i.e., the image of the operating system) through an internal physical storage unit of great capacity.

New method for manufacturing powder metallurgy magnets

The conventional method of press followed by furnace sintering is now substituted by an electrical consolidation method. This allows joining in a single step the previous pressing/sintering processes, and, due to the promptness of the process, the use of controlled atmospheres is not necessary. The steps of magnetization, and eventual thermal treatments, can be carried out in the same container, without being necessary to manipulate the product.

New method for manufacturing magnetic cores by powder metallurgy

Magnetic cores in amorphous state are usually produced by placing together very thin amorphous ribbons from a material obtained by the melt-spinning technique. The new patented method produces the amorphous material by mechanical alloying, a traditional process in the powder metallurgy field. This technique allows a higher control on the amorphisation process and the properties of the amorphous obtained powders. These powders are then consolidated by the very quick process known as Electrical Resistance Sintering (also Electrical Discharge Consolidation/Sintering can be used). A final amorphous material, without the typical frontier between ribbons of melt spinned materials, which clearly affect properties, is obtained.

New procedure for the genetic transformation of plant cells and kit for carrying out said method

The strategy for transformation is extremely simple and does not involves subcloning the gene of interest in any vector. The kit is not based on specific promoters or regulatory DNA sequences, thus it can be applied to many different plant species, from unicellular microalgae to higher plant protoplasts. Since the strategy is not based on specific promoter or regulatory DNA sequences, only the marker and the gene of interest sequences are inserted in the microalgal genome, avoiding the introduction of undeserible DNA sequences in the transformant strain. This is very important given the concern that transfer of exogenous DNA through transgenesis causes in the public opinion

Procedure for obtaining a renewable resource of metals from acid minewater, and the respective systems

Is known in the state of the art the recovery of metals from the acid aqueous solution that contain them, generally by liquid-liquid extractions. For metals recovery at industrial scale is necessary that these metals can be recovered simultaneously by means of a single extraction step. There are several extraction reagent for this purpose, all these reagent are very expensive and the industrial process for the metal recovery (particularly for rare earth and yttrium) are very complex and finally expensive. The present procedure allows to recovery selectively metals (particularly rare earths and yttrium) by the neutralization of acid mine waters. The objective is to revalue the metal content dissolved in this waters.

New procedure for the purification of water contaminated by metals and the respective systems

The invention solves the problems of inefficiency which usually shows the conventional passive treatment systems. The reactive fills developed for the removal of inorganic contaminants historically have focused on removing low concentrations of these (typical features of coal mining), however when these fillers are faced to high concentrations of metals (sulfur mining, uranium, industrial water waste…) quickly clogging and loss of reactivity occurs. The present invention allows the removal of metals without clogging and/or loss of reactivity. This is achieved by the use of a coarse inert material with high surface mixed with a fine-grained reactive material, so that the surface of the inert material is breaded with reactive material. Coarse fragments of inert material act as a frame, providing large pores that reduces clogging by precipitates. The small particle size of the reactive material provides a large surface area that increases its reactivity.

Power supply system controlled from internet for devices connected to a lan

Nowadays there are devices that allow the control of devices connected to a network from the own network. The classical method to access them from a different network is the redirection of the corresponding TCP or UDP connections to local networks from the border router. The redirection requires a high level of expertise in communications to be performed. Another strategy that is often used is the creation of VPN (virtual private network). This technique allows the control of access but does not allow connections to be discriminated or the management of power supply. The proposed system allows you to control the person and the moment to access as well as the free access. The modification of these constrains can be performed in the course of an access session. In addition, the system allows the control of power supply of the device you want access to. The interface is very friendly and does not require continuous changes in the configuration of the router. The system has a local database access control and validation can be delegated to other servers using protocol validation like LDAP, IMAP, POP3, etc.
