Abstract: A minimum quantity lubrication (MQL) system includes a controller, a lubricant module coupled to a tool spindle of a machining apparatus, and a pneumatic module coupled to the spindle. The lubricant module is configured to supply lubricant at pressure to the tool, as controlled by the controller. Likewise, the pneumatic module is configured to supply pressurized air to the tool, as controlled by the controller. The controller is configured to direct the lubricant module to supply lubricant prior to the controller receiving a START signal from a machine tool controller. Optionally, the lubricant pressure level is predetermined based on known characteristics of the tool that is coupled to the spindle. Optionally, the START signal is anticipated by referring to a signature/profile of the operational steps of a machining process where a timeline or time table of lubrication request intervals are identified.

Abstract: Embodiments relate to amino acid-based poly(ester urea)s with amino acid residues selected L-leucine, L-isoleucine, L-valine or combinations thereof. The amino acid-based poly(ester urea)S may optionally include a second amino acid residue selected from proteinogenic amino acids and non-proteinogenic amino acids. The amino acid-based poly(ester urea)s are particular useful for the preparation of vascular grafts. Due to the biocompatibility of the amino acid-based poly(ester urea)s, vascular grafts prepared from amino acid-based poly(ester urea)s with small internal diameters (i.e. less than 5 mm) may be prepared and inserted into a patient or animal, and provide a substantial decrease in the risk of failure compared to conventional polymers used in vascular grafts.

Abstract: Two axially parallel rolls are pressed against each other in a device for producing and/or treating a moving material web. Sensor elements are arranged in the force transmission path running from the force-producing elements via the rolls, outside roll bodies of the two rolls. As a result of displacing the sensor elements out of the roll bodies of the rolls, the production of the rolls is less complicated and less expensive. No sensors have to be embedded in the roll bodies, which opens up the possibility of using standard rolls. In addition, the occasional grinding of the rolls can in this way be performed without any regard to the sensor elements. Nevertheless, the pressure prevailing between the rolls can continue to be measured directly, since the sensor elements are arranged in the transmission path of the pressing force.
