Abstract: A power supply for a rapier head (1) of a rapier weaving machine, which is connected to a rapier bar which can be displaced in the longitudinal direction or to a band (2) which can be displaced in the longitudinal direction, is presented. The power supply includes an inductive coupling device with at least one primary induction coil (8) and with at least one secondary induction coil (9) which can be inductively coupled to the primary induction coil, with the secondary induction coil (9) being formed on the rapier bar or on the band (2) respectively.

Abstract: In accordance with the invention a thread carrying apparatus is proposed with a thread (2) lying in contact with or passing along the thread carrying apparatus with friction in the operating state. The thread carrying apparatus includes excitation means (3) for producing oscillations which reduce the frictional force between the thread (2) and the thread carrying apparatus. In this arrangement a resonator body (4) is provided with the thread (2) lying in contact with or passing along the resonator body with friction in the operating state. The resonator body (4) is designed in such a manner that the excitation means (3) produce resonant structural sound oscillations in the resonator body (4).

Abstract: The combination of a human medical vessel prosthesis (1) comprising a measuring probe (2) with a transponder, which measuring probe can be anchored to the vessel prosthesis, and allows the function of the vessel prosthesis to be monitored over longer periods of time. Suitable measurement parameters such as pressure values can be detected by the measuring probe (2) and be transmitted in a wireless manner with the aid of the transponder to a transceiver apparatus where they are available for evaluation.
