Abstract
A method of mixing a composition in the liquid state comprises enclosing the compositin in a tube, locating the tube in tube location means rotatably mounted on a member, spinning the member about a spin axis, and for at least part of the spinning period rotating the tube location means about its own axis of rotation parallel to the spin axis and spaced therefrom, so that the tube is subjected to both spinning and end-to-end rotation. Apparatus for carrying out the method preferably comprises a sun and planet gear assembly which rotates on the spin axis, the tube location means being coupled to planet gear of the assembly so that rotation of the assembly causes the spinning of the tube, and relative rotation between the sun and planet gears causes the end-to-end rotation of the tube.

A method of mixing a composition in the liquid state, comprising the steps of:
- enclosing the components of the composition in a tube;
- positioning the tube by tube location means carried by a member which is mounted for spinning about a spin axis, the tube location means being mounted for rotation relative to the member about an axis of rotation substantially parallel to said spin axis and spaced therefrom;
- and
- spinning the member about said spin axis for a period of time and rotating the location means about said axis of rotation for at least part of the spinning period;
- whereby the tube is subjected to spinning about said spin axis of the member, and to end-to-end rotation about said axis of rotation of the tube location means.
Apparatus for mixing a composition in the liquid state, comprising:
- a tube for enclosing the composition;
- a member rotatable about a spin axis;
- tube location means for receiving the tube;
- means mounting the tube location means for rotation relative to the member about an axis of rotation substantially parallel to said spin axis and spaced therefrom;
- means to cause the member to spin for a period of time about said spin axis;
- and
- means to cause rotation of the tube location means about said axis of rotation for at least part of the spinning period;
- whereby the tube is subjected to spinning about said spin axis of the member and to end-to-end rotation about said axis of rotation of the tube location means.
