Abstract: A system comprises at least one computer device in communication with one or more server computers. The system converts unstructured text into usable order details, and uses instant messaging to notify recipients of the order details. The notices include electronic web links that launch a web interface that generates an editable, pre-populated electronic order ticket based on the order details. Submission of the electronic order ticket launches an auction during which the recipients may respond with offers to fulfill to the electronic order ticket. If after the auction more than one response is needed to fill the electronic order ticket, the system automatically allocates how and in which order the responses will be used to fill the electronic order ticket. If the electronic order ticket is not completely filled after the auction, the electronic order ticket is submitted to one or more additional exchanges for further filling.

Abstract: An assembly that utilizes reusable sheaths for covering magnetic rods for collecting particles in an inverse magnetic particle process. The magnetic rod is removed from the reusable sheath to release particles at the same or a different location. The reusable sheaths can be assembled in a cylindrical plate, which can be rotated to position a clean sheath for each step of the inverse magnetic particle process. When not being used for particle separation, the sheaths can be washed of potentially contaminating solution in wash receptacles.
