Abstract: Sample traceability device and method for medical research and/or diagnosis. The invention relates to a sample traceability device for medical research and/or diagnosis, comprising a one-dimensional or two-dimensional optical code, the device comprising a system for reading one-dimensional or two-dimensional optical codes and a sample tracing control device comprising a sample tracing database manager, and a user interface screen. Said traceability device also comprises: an area for depositing at least two samples, a system for illuminating the deposit area, at least one digital camera oriented towards said deposit area, and a device for processing the image, said image processing device comprising: a module for locating said optical codes, and a module for reading the located optical codes, the sample tracing control device automatically receiving the information generated by the module for reading the located optical codes.

Abstract: A device for producing spun yarn by means of an airflow acting in a twisting manner on the fibers of an untwisted sliver (1) as the sliver is being conducted into and through a spindle assembly (3). The spindle assembly (3) comprises a spindle head portion (5) which conically tapers toward a spindle inlet opening (2) and is rotatable independently of a spindle core portion (7) through which the yarn is withdrawn. The device suppresses any tendency of the yarn strength to decrease at high, increasing numbers of spindle revolutions.
