The testing method for determining the electrostatic stability of fluid emulsions L1 and L2 using the device (100) is also described.

The present invention relates to a sliding component for use in internal combustion engines, provided with a ferrous base (10) coated with a protective surface layer (11) composed of at least one nitride and applied by physical vapor deposition (PVD) or a nitrided layer to the sliding peripheral surface (2) of which a diamond-like carbon (DLC) coating (12) is applied, the coating (12) comprising at least one transition layer (122) composed of WC1-x and/or of at least one layer (121) of chromium metal with a crystalline structure (bcc - body cubic center) located between the ferrous base (10) and an external layer of amorphous carbon (124).

The present utility model patent refers to an innovative use of any item of clothing (men's or women's, adult or children) fitted with a built-in RFID chip, intended to enable a series of new uses such as access control, personal tracking and product authenticity verification, among many others. The present invention comprises any item of clothing (1) fitted with an RFID chip (2) built into any part thereof and programmed to control access to places that require identification, admission or authorization to enter; for personal tracking; to check the authenticity of a product or even to replace personal documents, such that, for example, any item of clothing (1) fitted with an RFID chip (2) can be sold to afford the purchaser thereof admission to an event with controlled access, validating the admission thereof using a reader at the event site, admission being granted with or without a particular access ticket, and, once the purchaser has left the site, said RFID chip (2) expires, or not if the same events may be repeated at a later date, in which case the same item of clothing is revalidated for use at said later date, the wearer of the item of clothing (1) nonetheless being prevented from re-entering on the date already used; to enable the wearer of an item of clothing (1) with an RFID chip (2) to be tracked using GPS or any other system supporting such functionality; to authenticate the originality of the item of clothing (1) such that it is only authentic if it has a valid RFID chip (2) and finally to enable the user to wear one or more items of clothing (1) fitted with RFID chips (2) such that established authorities with readers can freely access the wearer's personal information such as ID card number (RG), individual taxpayer number (CPF) and driving license (CNH), inter alia, thereby obviating the need to carry physical documents.

The present invention pertains to the technical field of civil and military submarines, more specifically to a submarine (1) comprising an innovative hydrodynamic "hull" profile (2) that allows the submarine to navigate faster and the consumption of fuel to generate the vessel power to be reduced. These advantages are made possible by the reduced water resistance resulting from the bifurcated mouth (5) of the stern (A), in conjunction with two inner ducts (3) that extend from the front part, along the inner sides to the fore of the vessel, thus allowing the front intake and passage of water without offering any resistance, the water turbulence being utilised by the propeller (C), which takes advantage of the water displacement caused by the rotor, displacing the low water pressure near the rotation axis of the propeller (C) towards the front of the vessel, thus eliminating the water resistance.
