A method and an apparatus for measuring the grain-size of powders by measuring the changes in concentration of sedimentation liquids in a centrifugal field, wherein the displacement of two interconnected floats is measured in two separate sedimentation vessels.

Method and apparatus for measuring the grain-size of fine powders

This invention relates to an arrangement for separating for films, droplets and sprays from pipe-borne gas flows wherein a pipe is provided with a cross-sectional constriction adapted to accelerate the gas flow in the pipe and annular stripping slot having an annular baffle surface and communicating with a collecting trap, the annular baffle surface being adapted to receive the liquid-containing gas flow and to cause the flow to pass into the collecting trap.

Separator, especially for chimneys

To increase the degree of separation of liquid droplets from a stream of gas by means of a separator consisting of a packet of wire gauze arranged in a pipe, the packet is subdivided along its height by discharge channels arranged transverse to the direction of flow.
