Abstract: A method for determining the coefficient of friction .mu. between the wheel and the road is described. Assuming a moving vehicle, the brake pressure on a non-driven wheel (measuring wheel) is increased until a tendency to lock occurs. At the same time, the driving torque is increased so that the braking force of the measuring wheel and the increased driving force of the driving wheel on the same vehicle side equal each other. Additionally, an increased driving force of the second driving wheel must be removed by braking.

Abstract: This invention relates to a pan head (1) for supporting a device, preferably a film or television camera (2), having a stator (6) and a rotor (7) swiveling about a pitch axis (A) of the stator (6), whereby the rotor (7) supports the device (2). To permit determination of the torque between the rotor and stator with the device fitted on, and thus to facilitate e.g. the "balancing" of the fitted device in the zero position of the rotor (7), a torque sensor (31) is integrated into the pan head (1) for detecting the torque in several pitching positions of the rotor (7).

Abstract: A method for manufacturing a frictional locking member, in particular a synchronizing ring. The surface of a metallic base member (2) is provided with a frictional body made of a sintering powder.In order to simplify the method, the base member (2) is combined with an insert member (20). The insert member has centering means (24) for retaining the base member (2) in a defined position and at a defined distance (23) from the counter surface (22) arranged at a defined distance (23) from the surface (14). The cavity (27) formed by the defined distance (23) between the surface (14) and the counter surface (22) is filled with a sintering powder, and the insert member (20) is sintered together with the base member (2) with the cavity (27) filled (FIG. 4).

Abstract: A method of damping the rebound in print hammer magnets in typewriters or similar office machine in which kinetic energy is removed, in a manner known per se, from the armature of the print hammer magnet returning to its initial position by charging the coil of the print hammer magnet with a so-called braking pulse. The method provides the charging of the coil of the print hammer magnet with measuring pulses during the time when it returns into its initial position and to measure the current flowing through the coil. The increase in current depends on the width of the air gap and therefore permits conclusions as to the position of the armature, so that the braking impulse can be switched on at the correct time.

Abstract: The invention relates to a method and means for removing liquid from moist metal particles, substantially without causing oxidation, preferably from metal particles produced by means of liquid atomization of a casting jet, wherein the moist metal particles are collected in a space (1) and a non-oxidizing gas flow is blown through them, most of the moisture being caused to accompany the gas flow out of the space (1) and wherein the space, in which the metal particles are filled, is thereafter substantially evacuated so that any remaining liquid is vaporized and thus removed from the space (1).
