1. WO/2015/074126 METHOD FOR CONTROLLING FLUID INJECTION RATE IN DEPOSITS AND ADJUSTABLE FLOW REGULATORWO28.05.2015
E21B 43/20
PCT/BR2013/000503PETRÓLEO BRASILEIRO S.A. - PETROBRASRESENDE DE ALMEIDA, Alcino
The invention relates to a method for controlling the injection rate of water or other fluids in underground oil deposits, and to an adjustable flow regulator to be preferably used to implement the method. The method essentially consists in adding small and controlled quantities of a gas to the water, reducing the speed of sound, thus allowing a critical outflow through the flow regulator, in particular venturi-equipped flow regulators. The flow regulator has a central body in a conical housing that allows the area open to the outflow, and hence the injection rate, to be adjusted when an actuator is activated. Used in conjunction with the method, this flow regulator increases the advantages of the latter, including the fact that a wide range of injection rates can thus be assured by a single regulator.

PCT/BR2013/000504PETRÓLEO BRASILEIRO S.A.-PETROBRASPONTES BITTENCOURT, Roberto, Carlos
The present application discloses a method for producing hydrogen by catalytic decomposition of ammonia from acid water units. In a first step, the ammonia stream is purified in contact with various catalytic beds, removing chlorides and sulfur, and more specifically, ammonia is partially transformed into hydrogen in the bed formed by a catalyst based on alkalis and alkaline earths, supported on zinc oxide, alumina, silica-alumina and mixtures thereof, with nickel oxide as the active phase. In the second step, the purified ammonia stream is fed to the steam reforming reactor to generate hydrogen which is then purified. The application also relates to the catalyst used in the method.

The present invention pertains to a noise-reducing device for household appliances, more specifically to assist in reducing noise originating from the vibration of the capillary tubes of cooling systems produced by the expansion of cooling gas which runs through its inside. The invention is characterized by comprising means to promote the muffling of vibrations originating from operating frequencies varying from 250 Hz to 630 Hz in an expansion device (100), wherein said means comprise at least a body (2) comprising at least a groove (3) cooperating with the at least an expansion device (100), wherein the mass of the at least a body (2) is comprised within the intervalvarying from 8 to 18 grams.

6. WO/2015/074129 SITE FOR POSTING AND DISPLAYING VIDEO ADVERTISEMENTSWO28.05.2015
G06Q 30/02
PCT/BR2014/000411MAGNUS LEFFA, José AntônioMAGNUS LEFFA, José Antônio
A site is described for posting and displaying video advertisements, comprising an innovative website aimed exclusively at posting and displaying video advertisements on the worldwide computer network, where companies of any business branch can register and take part; the only condition for keeping the video on display is the offer by the advertisers of prizes to be awarded to Internet users who view the entire video posted, by means of a mechanism created by the inventor that causes the Internet user who is interested in winning the prize to view the advertisement from beginning to end. The registered company can post products or services for sale through e-commerce, and the Internet user that buys them can repeat their participation, increasing their chances of winning the prize, thus solving the problem found in the prior art, in which advertising videos are normally displayed on the Internet on the sites and virtual shops of the advertisers themselves, thus not attracting the attention of Internet users to the advertised product or service.

7. WO/2015/070298 CATALYST FOR LOW-TEMPERATURE STEAM REFORMING PROCESSESWO21.05.2015
B01J 23/80
PCT/BR2013/000485PETRÓLEO BRASILEIRO S.A. - PETROBRASLOGLI, Marco Antonio
The present invention relates to a catalyst for steam reforming processes, especially for the low-temperature water gas shift reaction step of steam reforming processes. The catalyst is constituted of copper, zinc and aluminium oxides, and has a sodium content from 200 ppm to 1200 ppm. The use of these catalysts in the LTS step reduces the formation of byproducts, in particular methanol, while retaining high activity and stability of the conversion reaction of carbon monoxide with steam.

8. WO/2015/070301 TUBER HARVESTING MACHINEWO21.05.2015
A01D 17/10
PCT/BR2014/000085CLEUSA DE FÁTIMA LIMA DE MACEDOVOGES DOS SANTOS, Jeferson
The international application relates to an agricultural machine for harvesting tubers (potatoes, carrots, onions, beetroots, etc.), to be coupled to a tractor (4) to be operated with the traction unit in reverse, so as to travel backwards on the crop field during harvest. The harvesting machine comprises three modules: a front carriage (1) that cuts and strips branches by means of slanted extracting knives (20); an intermediate carriage (2) in which the harvested product is cleaned and conveyed by a conveyor belt (24) to the third module, formed by the rear carriage (3), in which sorting is carried out by pickers carried on the side platforms (27). After sorting, the tubers are conveyed by the cleated conveyor (30) to the product packaging portion at the rear end of the machine. The machine components and mechanisms can be driven by the tractor power take-off, or alternatively by a hydraulic, pneumatic or electric system.

PCT/BR2014/000410SíMEROS PROJETOS ELETROMECÂNICOS LTDABERTONI, Fabiano
The present invention proposes a method for producing the configuration of a tensile armour (54, 55) of a flexible pipe (50), the method comprising an offset-producing step in which the end region (551a) of each wire (551) of the outer tensile armour (55) of the flexible pipe (50) is cut out, as well as the end region (541a) of each wire (541) of the inner tensile armour (54) of the flexible pipe (50), producing an offset between the end region (551b) of each wire (551) of the outer tensile armour (55) after the cut and the end region (541b) of each wire (541) of the inner tensile armour (54) after the cut, the offset having a suitable length (L) to allow a shaping step to be carried out, during which the end region (541b) after the cut of at least one wire (541) of the inner tensile armour (54) is shaped, so as to produce a shaped end region (541c) with an anchoring profile. The present invention also proposes a configuration for a tensile armour (54, 55) of a flexible pipe (50) produced by the above method. According to the proposed solution, after the wires (551) of the outer tensile armour (55) are cut with an offset relative to the wires (541) of the inner tensile armour (54), likewise after the latter are cut, the wires (541) of the inner tensile armour (54) are exposed and can be easily accessed in order to shape the end regions (541b) thereof after the cut, without the need to fold back the wires (551) of the outer tensile armour (55).
