Abstract: The multi-part neutral electrode (1) comprises three flat part-electrodes (2, 3, 4) which are arranged adjacent to each other or one above the other. In order to improve the monitoring of the contact of the part-electrodes on the body of the patient, the electrode is so designed that the two outer part-electrodes (2, 4) form substantially triangular bearing surfaces, that the long edges (hypotenuses 8 and 9) of the outer part-electrodes extend parallel and at a distance apart, and that a central, strip-shaped part-electrode (3) is arranged between the hypotenuses of the outer part-electrodes. As a result of this design of the three-part neutral electrode, a detachment axis of symmetry is avoided, along which the neutral electrode could be detached from the body of the patient in such a manner that the detachment alarm of the monitoring circuit is not triggered until the electrode is already so far detached from the patient that the danger of burns exists for the latter.

IPC: G01L13/00
Filed: 1990-03-02
Abstract: The vapor pressure of a multi-component liquid composition is measured by providing an eductor 10 through which the liquid composition is caused to flow at selected inlet pressures to provide incrementally changing pressure differentials across the eductor. The pressure differen­tial is read for each incremental change across the eductor and the suction port pressure is read at each incremental pressure differential until the suction port pressure as a function of the pressure differential indicates a change in slope or point of inflection along the so-called dead fluid curve indicating the bubble point or true vapor pressure of the liquid composition. A motorized pressure regulator valve may be interposed in the liquid composition flow conduit upstream of the eductor for incrementally changing the pressure differen­tial. The point of inflection may be obtained by determining the mathematical relationship using the cubic spline fit technique and calculating the second derivative of the function of the suction port pressure versus the pressure differential across the eductor until the second derivative equals zero.
