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: A fastening system for medical devices includes a column-shaped interface profile (1) having a lens-shaped cross section with at least one convexly shaped, longer front surface (2) and with two shorter lateral surfaces (3), which are parallel to one another and pass over into the longer front surface (2) via a tappet-shaped projection (4) each. A clamping device (6), fits the longer front surface (2) of the interface profile (1) with the two tappet-shaped projections (4) in a positive-locking manner for fastening medical devices. The clamping device (6) has a concavely shaped outer surface and is provided with clamping jaws (8) that can be set on one side or on both sides for detachable fixation on the interface profile (1). This construction offers the possibility of receiving medical devices and accessories on up to a maximum of four sides simultaneously, especially also via standardized rail elements (7).

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: Textile articles to be treated are fed on to shapes fitted to supporting members. Gliding independently each other on a platform of the boarding or semi-boarding machine, and positioned in mutual contact at respective sides along a polygonal pathway defined by a guiding device. The supporting members are transported in step along the polygonal pathway, by the engagement with a towing device acting independently at each linear stretch of the polygonal pathway, so that in each step at least one position at the concurrence of two linear stretches of the polygonal pathway is maintained unoccupied. At least one of the supporting members, on which the textile articles to be treated are fed, is arranged in a halt position upstream from a semi-boarding station and then is moved to take the shapes into the semi-boarding station. After the semi-boarding treatment, this supporting member is transferred to a station where the textile articles, treated, are extracted from the shapes.

Abstract: A stabilizer arrangement for a motor vehicle has a stabilizer (1), which is connected to the vehicle chassis and which is connected to a spring-mounted wheel carrier part on each side of the vehicle by a piston-cylinder unit (4; 4?) each. Each of the piston-cylinder units (4, 4?) is formed of at least one piston (8, 8?) arranged movably in a cylinder (7, 7?), and each is connected in an articulated manner, at one end, to one end of the stabilizer (1) and, at the other end, to a spring-mounted wheel carrier part. The piston-cylinder units (4, 4?) are connected to a hydraulic pump (20). A stop (13, 13?), against which the respective piston (8, 8?) can be moved, is assigned to each of the cylinders (7, 7?). By an arrangement of valves, it is made possible for the pistons (8, 8?) to move out of each position in a purposeful manner against the stop (13, 13?) and to hold there in a defined position in order to restore the stabilizer action in a purposeful manner and effectively from any position of the vehicle.

Abstract: A suspension device is provided for the spring-loaded suspension of a weight body (3) relative to a substructure (1) such as a vehicle body, a cab (3) of a truck relative to the vehicle chassis (1). The suspension device has a spring/absorber device (2) arranged between the weight body (3) and the substructure (1) for absorbing shocks and vibrations. The suspension device includes at least one Watt's linkage arrangement (6) connecting the weight body and the substructure for reducing the degrees of freedom of motion of the weight body (3).
