Abstract: The invention relates to a method and a device for protecting fuel injectors in a turboshaft engine. The protection is carried out by injecting compressed air directly into the injectors. The air thus directly purges the injectors and evacuates the fuel present in them into the combustion chamber.

Abstract: A process to prepare new catalysts made from mixed metal oxides of transition metals, which involves the preparation of precursors and synthesis of these materials in oxide form from the preparation of a sol-gel formed from inorganic salts of these metals. An advance in the preparation of these catalysts made of mixed transition metal carbides and nitrides is proposed, providing an alternative way to the process of synthesis by solid-state reaction. The final product, in extruded form, has textural and mechanical properties superior to those obtained by the known techniques in the state of the art, and with better catalytic activity for hydrotreatment reactions.

Abstract: A process to prepare multi-metal materials based on transition metals, using co-precipitation of mixed compound from solutions containing the metals, more specifically a process to prepare multi-metal materials based on transition metals, using co-precipitation, preferably seeking a condition of formation of a gel, from the mixture of precursor solutions containing the metals. The parameters of the process are set in such a way that the material is able to be molded by extrusion, obtaining extruded material with superior physico chemical properties, which may be used as an adsorbent, a catalyst or catalyst support, or even as filler in the reactor or column.

Abstract: The invention relates to a device (17) which is used to spray a coating product in powder form onto a part (5), particularly for automatic retouching, and which is intended for an application booth (3). The invention is characterised in that it comprises: an essentially-vertically column (18), at least two carriages (19) which can move independently in an essentially-vertical manner along the length of the column (18), and coating product-application guns (10) which are supported by the carriages (19).

Abstract: A machine (4) is provided for removing dust from carbodies, before the paint coatings are applied to said bodies. Said machine is built on the principle of feather rollers rotary mounted about their central axis and rotationally driven, such as to engage the carbodies moved forward on a conveyer. At least two feather rollers (26, 27) extend one after the other, and are synchronously driven, with the angle between the respective axis (28, 29) of the consecutive rollers (26, 27) being adjustable by changing the tilting of at least one of their axis (28, 29). The machine can therefore accommodate varying carbody profiles. Such a design is applicable to dust removing roof and side machines.
