A method for treating organic waste having a liquid component and a solid component, which comprises the steps of: weighting the organic waste with ash to accelerate sedimentation of the weighted organic waste; separating the weighted organic waste to isolate the liquid component from the solid component; chemically reacting the solid component to substantially lower the oxygen demand of the solid...

A space communicating with the atmosphere via a cavity and a passage is supplied with a fluid or drained by means of a tube (10) made of a flexible elastic material and having a tendency to coil up. Upon insertion into said space, the tube (10) is first held in a straightened-out condition by means of a guide (15) of flexible but unelastic material which is introduced into said tube (10) and then ...

Respiratory apparatus of the type in which a large proportion of the exhaled air circulates via a carbon dioxide absorber, with fresh gas being added. The fresh gas is prewarmed by being brought into heat-exchange contact with a reaction zone of the carbon dioxide absorber 4, after which the fresh gas is mixed with the recirculation air.

To fix a road vehicle seat for a child and/or an object to the seat or safety belt cushion, the body of the seat has apertures for connection of an arch and/or holder component for the object. - When the arch is connected to the seat, it is used for anchoring purposes using the ordinary seat belt of the vehicle, the central part of the belt extending through the arch.
