This is a device formed by a metallic bar ( called the agitation bar ) which is normally covered by a plastic layer, and a sheet that has underneath it a rotatory magnet or a series of electromagnets arranged in a circular form to create a magnetic rotatory field.

At this time there were thirteen machine areas registered on the Ravenswood Gold Field with the Mining Warden's report recording that the only method in use here ( Ravenswood ) for dressing mundic ore is by the ordinary stamper mills and rotatory buddles, resulting in a great loss of mineral.

In full flexion the movement of the radial head is hampered by the compression of the surrounding soft parts, so that the freest rotatory movement of the radius on the humerus ( pronation and supination ) takes place in semiflexion, in which position the two articular surfaces are in most intimate contact.

Hence, when inferior rectus contracts so we look down, superior oblique also contracts to prevent extorsion of the eye, and when superior rectus contracts so we look up, inferior oblique contracts to prevent intorsion, thus the undesired rotatory actions of the inferior and superior recti about the long axis of the eye are cancelled out.

In a paper published in 1919, Perucca reported an experiment which produced optical rotatory dispersion ( ORD ) as a result of passing chiral as a crystal, but in its natural ( undyed ) state is transparent and does not exhibit enhanced optical activity, so Perucca added an organic dye ( an equilibrium racemic mixture of a triarylmethane textile dye then known as " extra China blue " ).

The difference between the prismatic and antiprismatic symmetry groups is that "'D " p " h "'has the vertices lined up in both planes, which gives it a reflection plane perpendicular to its " p "-fold axis ( parallel to the { p / q } polygon ); while "'D " p " d "'has the vertices twisted relative to the other plane, which gives it a rotatory reflection.
