A method of reducing the oxygen content of a powder is provided. A canister is prepared with a getter, filled with the powder to be densified, sealed and evacuated. The canister is subjected to a hydrogen atmosphere at an elevated temperature whereby hydrogen diffuses into the canister through the walls thereof. The hydrogen forms moisture when reacted with the oxygen of the powder and the moisture in the reacted with the getter in order to remove oxygen from the powder to the getter. The atmosphere outside the canister is then altered to an inert atmosphere or vacuum, whereby hydrogen diffuses out of the canister. A dense body having a controlled amount of oxygen can thereafter be produced by conventional powder metallurgy techniques.

Container for liquid with dispersion device

Apparatus for producing air-saturated water

Cleaning device arranged in front of the inlet to a waterway

Filter for separating off liquids of high viscosity

Oil-clearing element having two or more movable floating bodies

Less viscous liquids (7) such as diesel oil may be unintentionally spread on water surfaces or on the ground (6). Loose sawdust (2) or chemicals are used to clear said surfaces (6). These clearing aids (2) with the liquid (7) absorbed in them are difficult to remove. The use of cases (5) of filter material, filled with sawdust (2) provides an aid which is easy to remove when the liquid has been cleared.
