1. WO/2015/051477 DREDGER ACTUATED FROM LANDWO16.04.2015
E02F 5/28
PCT/CL2013/000073QUIDIANTE DIAZ, Heriberto FloridorQUIDIANTE DIAZ, Heriberto Floridor
The invention relates to a drag dredger for the removal and cleaning of sediment in bays, port entrances, navigable channels, docks, watercourses, lakes or reservoirs, which is provided with means for excavating, dragging and removing the bottom of the waterway and means for regulation and support, the driving force for which is provided from land, which facilitates extraction of sediments directly onto the land, immediately leaving a planar surface on the sea bed. The aforesaid is achieved by controlling the excavator means and very closely controlling the cutting depth, all in a shorter period of time and at lower cost. The dredger is characterized in that it is formed from a frame provided with a drag scoop (1) that can move vertically by means of the use of a hydraulic or mechanical mechanism (6), in order to control cutting (drag cutting angle), as well as comprising transverse (3) and longitudinal (2) beams with crow-foot chains (8) for dragging the dredger. In addition, coupled to said frame, are at least four leaktight runner means or systems (4) to allow dragging with a lower blade (9) at a cutting angle, said lower blade being located on the lower peripheral edge of the scoop (1). The leaktight runners (4) prevent the dredger from sinking into the bed or into the material to be extracted.

7. WO/2015/035528 PORTABLE AND SUBMERSIBLE VIEWING DEVICE FOR VIEWING THE INTERIOR OF ELECTROLYTIC CELLSWO19.03.2015
C25B 15/06
PCT/CL2013/000066NEW TECH COPPER SPA.AYLWIN GÓMEZ, Pedro Alejandro
It is very important that problems that occur to the interior of metal-producing electrolytic cells are viewed in a timely manner because it allows solutions to be implemented in order to avoid production losses, before the situation deteriorates. Attempts have been made to view the inside of metal-producing electrolytic cells using small video cameras submerged in the electrolyte, that require an electrical power supply via cables. This is not only inconvenient but also poses a risk of electrocution due to the presence of currents in wet and aggressive environments (with acid or basic mists), at temperatures of 50°C or higher, and in areas where personnel circulate. In addition, the electrical currents circulating in the electrolytic cells generate very intense magnetic fields that greatly distort the images displayed on the cathode ray tube screens. In order to view the interior of the metal-producing electrolytic cells, we have designed a portable submersible viewing device consisting of at least one mini digital video camera that is sensitive to a wide spectrum of wavelengths and which is rigidly mounted on the interior of a sealed and leaktight compartment. Said compartment has a transparent window in front of the lens and is securely joined to a telescopic or fixed-length tube having a handle for the manipulation thereof. The mini digital video cameras used in this invention are connected, by means of cables having universal serial connectors, to a portable battery-powered computer, portable tablet, or similar, which provides energy for the operation of said cameras and for simultaneous illumination, allowing the images of the interior of the cell captured by the cameras to be displayed in detail on the screen. This eliminates the problems of image distortion and the problems caused by the power-supply cables, and facilitates working with tools inside the cell, thereby solving any problems before it is necessary to suspend operation.

8. WO/2015/035529 ANTIVIRAL AND ANTIMICROBIAL MATERIALWO19.03.2015
PCT/CL2014/000044SILVA DIAZ, MauricioSILVA DIAZ, Mauricio
The present application relates to an antiviral and antimicrobial material that can be used to produce fabrics or sheets, intended preferably for the textile industry, as well as for the clothing industry and agriculture. The aforementioned material is suitable for use both in garments and in filters, agricultural containers and other elements which require protection and in which textile can be used. In addition, the invention relates to the production method and to its use in the textile industry. There is currently great interest in maintaining areas, environments and the skin of people free of bacterial germs and microorganisms that damage end products during processing or are harmful to these same people, as with any item equipped with cloth that is to be kept free of agents harmful to human health, products or the surrounding environment. Moreover, at present there is no known cloth that uses copper, with its colour, its particular sheen and, above all, its antiviral and antimicrobial characteristics, that would be suitable for use in implements, clothing, filters or parts of same. The aim of the invention is to provide an antiviral and antimicrobial material that solves the problem described above. The production of the antibacterial material with copper filaments allows said material to be used essentially in garments, safety implements, hygienic elements and filters that must be free of contaminants, to be applied to plant products during packing or when packed, and to be used in assisting in the growing of trees and protecting same since copper plays an active role in the photosynthesis of plants. The invention is based on the creation of a yarn for producing fabrics with a surface that can be kept free of contaminants, such as bacteria, viruses and fungi that are harmful to health, the natural environment, natural products and the surroundings.
