Patent GB-918799-A (GB)
Title: Improvements in or relating to the manufacture of sintered metallic bodies
Inventor: GRIMWADE MARK FREDERICK
IPC: C22C1/10
Filed: 1960-12-08
Abstract: A sintered metallic body comprising a matrix such as Ni, Co, Fe, Cu or Ag and containing a dispersed refractory oxide phase such as Al2O3, MgO, BeO, CaO, ThO2, Cr2O3 and the rare earth oxides is produced by heating a molten mixture of a compound of the matrix metal and a soluble compound which decomposes to form the refractory oxide, rapidly p  cooling the homogeneous melt, crushing to a powder and heating without melting to form the metal oxide/refractory oxide mixture which is then heated in hydrogen to reduce the metal oxide, the final powder mixture of metal and refractory oxide being pressed and sintered.  The metal compound is preferably a salt such as a hydrated nitrate and the soluble compound which forms the refractory oxide is also preferably a nitrate, the refractory oxide forming not greater than 5% by volume of the matrix metal. The matrix metal salt may be melted first and the refractory oxide compound added to the melt or the compounds may be mixed in the solid state and melted together.  The melt is rapidly cooled in a water jacket or by pouring the melt into a chilled mould.  The crushed powder is preferably decomposed by first dehydrating the salts under vacuum and then heating at a low temperature to avoid sintering and melting. Examples are given of the production of sintered Ni/Al2O3 formed from the molten nitrates, the final powder mixture being pressed at 35 tons p.s.i. and sintered in vacuum at 1250 DEG  C., Ni/MgO and Ni/ThO2 the sintered body containing 2% oxide in each case.  The sintered compacts are hot rolled at 800 DEG  C., hot swaged, annealed and drawn into wire.

A machine for inducing flow of fluid comprises a cylindrical bladed rotor which is open at one end and co-operates with guide means to define an entry zone and an exit zone within the rotor and an intermediate zone outside the rotor, the fluid flowing outwardly through the rotor blades from the entry zone to the intermediate zone and then inwardly through the rotor blades to the exit zone, the fluid entering and leaving the machine with an axial component of velocity. In the machine shown, fluid flows in a generally axial direction into an entry zone 19<SP>1</SP> bounded by a stationary guide member 15<SP>1</SP> and then flows radially outwardly through rotor blades 30, 3<SP>1</SP> and intermediate stator blades 31 to an intermediate zone 11<SP>1</SP>. Zone 11<SP>1</SP> is provided with a member 161 which extends close to the rotor blades 31 to minimize leakage between the entry and exit zones. Guide blades 33 direct the flow back towards the rotor. After passing radially inwardly through the blades 3<SP>1</SP>, 31 and 30 to an exit chamber 20<SP>1</SP>, the fluid leaves the machine axially.
