Abstract: The present invention relates to a method for treating fragments of polyvinyl butyral (PVB) in which glass shards are encrusted in or on the surface of the PVB. The method involves placing PVB fragments in contact with an aqueous solution comprising a cationic surfactant and a weak base, to obtain a mixture. This mixture, subjected to ultrasound within a defined temperature range, leads to separation of the glass shards and the PVB.
In particular, the inventors have discovered that the combined, simultaneous, and complementary action of a weak base, a cationic surfactant, and ultrasound, at an appropriate temperature, made it possible to detach and/or unembed the glass shards fixed to the collected PVB without degrading the polymer matrix.

Abstract: The object of the present invention is to produce a metal part equipped with a protection system, particularly for turbine blades for aircraft engines, having a thermal barrier that is improved in terms of thermal properties, adhesion to the part and resistance to oxidation/corrosion. In order to achieve this, the method according to the invention produces in a single step, from specific ceramics, coating layers using SPS technology.According to one embodiment, a metal part is produced according to an SPS flash sintering method and comprises a superalloy substrate (22), a metal sub-layer (21), a TGO oxide layer (25) and the thermal barrier (23) formed by said method from at least two chemically and thermally compatible ceramic layers (2a, 2b).A first ceramic (2a), referred to as the inner ceramic, is designed to have a substantially higher expansion coefficient. The outer ceramic (2b) is designed to have at least lower thermal conductivity, and a sintering temperature and/or maximum operating temperature that is substantially higher. The thermal barrier (23) has a composition and porosity gradient (3) from the metal sub-layer (21) to the outer ceramic (2b).

Abstract: A method for equalizing a signal comprising modulated symbols comprising a block of N received symbols comprises: demultiplexing the N received symbols by factor L to generate a predetermined number L of sub-blocks of symbols, each comprising a version of the N received symbols sub-sampled by factor L, the independent equalization of each sub-block using an identical equalization algorithm, multiplexing the equalized symbols of each sub-block to obtain a block of N equalized symbols, removing instances of interference linked to paths other than two paths of higher power comprising generating an interference term resulting from the influence, on the equalized symbols, of all paths of the channel having the impulse response of the transmission channel except two paths of higher power, subtracting the interference term from the symbols of the block of N received symbols, and, a second equalization step equal to a second iteration of the first equalization step.
