1, Combustion chamber for a turbo-compressor unit associ- 

 ated with an internal combustion engine operable for reheat- 

 ing gases upstream of the turbine of said lurbo-compressor 

 unit, said combustion chamber being adapted to be supplied 

 with fuel and at the same llmeliy exhaust gases emerging from 

 the engine and by fresh air taken through a bypass pipe con- 

 nected between the outlet of the compressor and the inlet of 

 said turbine of said turbo-compressor unit in bypass relation 

 to the engine, said combustion chamber comprising a lubular 

 element having a closed end and an open end. at least one fuel 

 injector located toward the closed end of the lubul.ir element, 

 a primary air intake conduit adapted to communicate with 

 said bypass pipe and having an outlet arranged to introduce 

 fresh air into the tubular element in a combustion /one in the 

 vicinity of its closed end, an exhaust gas intake conduit 

 adapted to communicate with the exhaust outlet of the engine 

 and having an oulet arranged to introduce the cxhausl gases 

 into the tubular element in the neighborhood of iis open end 

 at a mixing zone located itownstre.im of said combustion 7one 

 and wherein the primary air or the products of combustion 

 thereof with the fuel Tirst meet the exhaust gases. s.u-J cvhaust 

 gas conduit outlet being orienled to effect said introduction 

 with minimum load loss and in the direction of Ilie open end 

 of said tubular element, and a secondary air iiil.ike conduit 

 adapted to communicate with said bypass pipe .ind having an 

 outlet arranged to introduce fresh air into the tubul.ir element 

 downstream of the upstream end of said mixing /one. said

I. Protective system against the heaving action of waves of 

 water comprising a bulky obstacle means having a spreading- 

 out surface and providing a substantially uninterrupted im- 

 pingement area of substantial extent athwart the wave path 

 and exposed to the impact ot successive surges of the heave 

 to induce along said spreading-out surface alternate ascending 

 and descending motions of a mass oi water of a thickness 

 greater than a limit layer of water, and means providing a 

 multiplicity of energy dissipating material elements distributed 

 over and projecting in front of said spreading-out surface a 

 distance sutficient to penetrate into said mass ot water beyond 

 said limit laser, said elements serving to slow down ascending 

 and descending water motions and phaseshift the same with 

 respect to the heave.
