Abstract
A centrifuge may include a main drive system having a first axis of rotation and a bobbin carrier having a bobbin axis of rotation that is parallel to and offset from the first axis of rotation. A transmission system may be connected to the main drive system via a differential in order to transmit power from the main drive system to rotate the carrier bobbin around the first axis of rotation and to rotate the carrier around the bobbin axis of rotation such that the bobbin can rotate around the first axis of rotation at a different speed than the bobbin rotates around the bobbin axis of rotation.

A centrifuge comprising a:
- a main drive system having a first axis of rotation;
- a bobbin carrier for mounting a bobbin so as to have a bobbin axis of rotation that is parallel to and offset from the first axis of rotation;
- a first transmission system connected to the main drive system and the bobbin carrier to transmit power from the main drive system to rotate the bobbin carrier around the first axis of rotation and to rotate the carrier around the bobbin axis of rotation;
- a first bobbin drive system connected to the transmission system for driving the bobbin carrier around the bobbin axis of rotation;
- wherein the first transmission system is connected to the bobbin carrier by a differential, such that the bobbin can rotate around the first axis of rotation at a different speed than the bobbin rotates around the bobbin axis of rotation.
A centrifuge comprising:
- a main drive system having a first axis of rotation;
- a outer carrier connected to the main drive system which rotates around the first axis of rotation;
- a bobbin carrier within the outer carrier for mounting a bobbin so as to have a bobbin axis of rotation that is parallel to and offset from the first axis of rotation;
- a first bobbin drive system connected to the outer carrier for driving the bobbin carrier about the bobbin axis of rotation;
- a first differential connected to the first bobbin drive system;
- a second bobbin drive system connected to the bobbin carrier so as to drive the bobbin carrier around the bobbin axis of rotation independently of the first bobbin drive system;
- a second differential connected to the second bobbin drive system;
- wherein the first and second differentials are connected to the first and second bobbin drive systems such that the bobbin is rotatable about the first axis of rotation at a different speed than the bobbin is rotatable about the bobbin axis of rotation.
