Title: Automatic cut-off valve for injection cannulas - comprising movable elastic O-ring on conical structure
Inventor: FLESCH UDO DIPL PHYS
IPC: A61M39/26
Filed: 1974-03-28
Abstract: In the cut-off valve for cannulas of injection and blood-sampling instruments, there is an elastic O-ring on a conical structure. It is shifted by the connecting piece of the above-mentioned instruments. In the closed position, the O-ring is placed in a groove. The cut-off valve, therefore, releases connection to the cannula, when an instrument is connected to the cannula, and automatically closed, when the instrument is being separated from the cannula. The use of fresh cylinders is not strictly necessary. As the cannula is being antiseptically closed by the valve, there is enough time for emptying and re-using the cylinder.

Title: Rotational speed sensor using gyroscope and combined torsional system - has rotational mass combining with rotational spring
Inventor: EWER HARTMUT ING GRAD
IPC: G01C19/56
Filed: 1974-12-13
Abstract: The rotational speed sensor operates on the gyroscope principle in which a rotational mass cooperates with a rotation spring as a torsional oscillatory system. The consequential precession moment is derived as a measure for the rotational speed. By comparison between the phase relation of rotational oscillation of the gyroscopic mass and the precession moment the flexure of the torsion strip or the the bending of the gyroscopic mass is ascertained. For production of effective damping, the resonance frequency may be made dependent upon the rotational speed.
