Abstract: The ultrasound converter, which is pressure-proof, hot water resistant and insensitive to temperature changes, consists of a converter housing (1), an oscillating element (2) with a piezo disc (3), electrodes (4; 6), and a power cable (7). In the space between the floor of the housing (5) and the rear electrode (6) is an ultrasound-insulating medium, preferably a synthetic foam. The oscillating element (2) rests on a shoulder (13) of the converter housing (1), and is axially rigid and radially movable. Its outer surface is distanced from the converter housing (1), and it is sealed against the converter housing (1), and held elastically, by an elastic seal (14). Openings (16), which are permeable to water vapour, are arranged in the housing floor (5). The front electrode (4) extends to the rear face of the piezo disc (3). A plastic film or an O-ring can be used as the elastic seal (14). If the ultrasound converter is used to measure the flow rate in a pipe, the diameter of the piezo disc (3) is greater than the internal diameter of the pipe.   <IMAGE>

Abstract: To reduce spurious sparks, and then misfire of an ICE having a magneto with an E armature, upon approach of a magnet (23) in a pole wheel (13) to the leading leg (26) of the E core at high speed ranges of the ICE, the magnetic reluctance of the magnetic path which includes the leading legs (26, 26a) of the E core (14, 14a) is increased with respect to that of the magnetic path which includes the trailing core (25), so that the inductivity of the magnetic circuit including the leading leg is decreased. This can be achieved by providing a wider air gap (X) at the leading leg (26) than at the center leg (15) and the trailing leg (25) of the E core; or reducing the cross-sectional area, or effective magnetic cross-sectional area, e.g. by reducing the number of laminations of the core, at the leading leg or reducing the size of the pole shoe surface (27) facing an air gap which is the same for all legs. A uniform air gap facilitates assembly of the E core. An additional air gap (28) can be introduced in the magnetic circuit which includes the leading leg (26a).

Abstract: The method is for detecting the coefficient of friction (mu) used for one braking operation between the wheels (16, 20) and the road for two axle groups (H rear, V front) each containing one of the wheels and one of the brakes (15 or 21). The braking system operating the brakes provides approximate stabilisation of the distribution of the braking power. The method involves first determining the axle group load distribution and the height of the centre of gravity (h) typical for the type of vehicle. For at least one braking operation the instantaneous braking power is then measured and from the instantaneous effective braking powers (pV, pH), the wheel braking factors (AV, AH), the relationship derived in (a) and the value in (b) the coefficient of friction is calculated.
