Abstract: The present invention nondestructively analyzes the position or corrosion state of a magnetic material present in the interior of a non-magnetic material structure. The magnetic material is magnetized from the outside of the structure, and magnetic flux density of the thus-magnetized magnetic material is measured at the outside of the structure, to thereby specify the position of the magnetic material or to analyze the corrosion state of the magnetic material. The magnetic material is magnetized in two stages. After the position of the magnetic material magnetized through first-stage magnetization is specified through measurement of magnetic flux density of the magnetic material, the magnetic material is demagnetized through application of an alternating magnetic field.

Abstract: An electroimpedance tomograph including a plurality of electrodes placed on a body, measuring circuits processing voltage signals recorded by the electrodes, and a control unit supplying two electrodes each with an alternating current. The control unit has a preset feed frequency. The control unit processes the processed voltage signals of all other electrodes to reconstruct the impedance distribution of the body in the electrode plane. The control unit provides for an automatic setting of the current feed frequency/frequencies to record a background frequency spectrum by detecting the electrode voltage signals over a preset period of time and record them as a voltage time series and transform them into a frequency spectrum. The control unit searches in the background frequency spectrum for a frequency (different states) or frequencies (different frequencies) that leads to a useful signal to background ratio above a preset threshold value when used as a feed frequency.

Abstract: Firefighting bucket (11) suspended from an aircraft by lines (15), has open top (12A) and a valve at base (13). The valve is attachable to the aircraft by remotely actuatable line (16) and independent movement of lines (15-16) may utilise the weight of the water to facilitate opening and closing of the valve. Dynamic sensing of a bucket attribute, e.g. weight, enables bucket (11) to be filled or discharged by a pre-determined volume by the pilot. Chemical fire retardant may be added by entraining it with water discharging from the valve.

Abstract: A process, system and device are provided for automatically recording pressure-vs.-volume curves during artificial respiration with a respirator. The inspiration pressure is increased during the supply of a breathing gas volume flow under the control of a control unit. The resulting breathing gas volume flow rate is detected and the volume is determined from the latter by integration. The control unit compares the breathing gas volume flow detected during the phase of expiration with a preselected set point and acts on an expiration valve (12) in the expiration line (8) by means of a controller in case of deviation from the set point in order to return the breathing gas volume flow to the set point.
