Abstract: The invention is directed to ion-capture compositions for ingestion and methods of use thereof. An aspect of the invention is drawn towards a method for selectively capturing at least one ion from the digestive system of a subject, the method comprising administering orally to the subject the ion-capture composition.

Abstract: A novel machine tool featuring a rotary tool changer is disclosed. In one embodiment, the tool changer is pre-tensioned, preferably by a counterweight, to improve repeatability when shifting from one tool to another. In another embodiment, the machine tool is principally a 3D printer, and features a novel cleaning mechanism that improves print quality, especially when printing elastomeric materials. In another embodiment, the machine tool features a rubbing tool that is heated and passed over the surface of a workpiece to improve the smoothness and precision of the workpiece.

Abstract: The invention is directed to ion capture devices and methods for ion capture.

Abstract: A peristaltic pump has an arcuate raceway with a partially concave inner surface extending through an arc of at least one hundred eighty degrees (180°). The arc defines a midpoint, and a rotor faces the inner surface of the raceway and is both rotatable relative to the raceway and translationally movable relative to the raceway between a pump position, wherein the rotor is spaced from the midpoint a first distance, and a tube load position, wherein the rotor is spaced from the midpoint a second distance greater than the first distance. A motor is coupled to the rotor to rotate the rotor plural are rollers arranged on the rotor to contact tubing disposed between the rotor and the raceway when the rotor is in the pump position. The motor is prevented from stopping at a predetermined angular position to facilitate loading and unloading tubing.
