Several species of capsules were tested.The initial
investigation used rigid capsules of anomalous shapes.
Each one of 10 different kinds of the cylindrical rotary
capsules \x0edrDs0.64 and 0.80,lrds6.was tested for
three apparent density \x0e rs0,0.10 and 0.20..A set of
rifle lines \x0emilled helical slots of rectangular cross-section.
on the capsule surface was used as a device causing that
the capsule moves in the pipe will rotate around its longitudinal
axis.The individual tested capsules differed by
number,width,depth and lead of the slots \x0esee Fig.1..
Also,a set of three conoidical capsules \x0eone-,two- and
three-stage capsules.of apparent density 0.10 and 0.20,
drDs0.8 and lrds6,as well as comparative cylindrical
capsules of the same size and density,were investigated.
Further on a separate group of capsules it was tested.
The capsules are semi-rigid so their shapes can adjust to
the outer forces w4x.In contrast to the ‘‘paste slugs’’ w5,6x,
the semi-rigid capsules were created by container of cylindrical
shape with rounded ends made from plastic foil and
packed by liquid or loose material charge \x0esee Fig.2.
