    • A device is proposed to determine the rotational speed of a transfer element (3) arranged in variable-diameter pulleys (1, 2) of a continuously variable transmission system, the said device Consisting of a sliding stock (4, 15), with a sensor (10, 16) which is supported on the transfer element (3) on the inner sides of the variable-diameter pulleys, which sliding stock is connected to the transmission case (8) by a spring (6) loaded rocker arm (5) mounted in a swivelling joint (7).With the knowledge of the peripheral speed of the transfer element (3), the rotary speeds (N1, N2) of the set of variable-diameter pulleys (1, 2) and the effective transmission radii (r1, r2), the slippage can be determined between the transfer element (3) and the sets of variable-diameter pulleys (1, 2). By comparing the previously established maximum amounts of slippage with the detected amounts of slippage, the maximum requisite pressure applied by the axially shifting variable-diameter pulley (9) in each set of variable-diameter pulleys (1, 2) can be adjusted to the optimum amount (see FIG. 1).

    • The tire pressure sensor (13) for monitoring vehicle tires is fastened radically relative to the wheel axis at the circumference of a wheel rim and includes a reference pressure chamber (20) with a contact pin (22) which cooperates with an electrically conductive diaphragm (21) closing the reference pressure chamber (20) toward the tire. An added mass (30) is fastened freely at the diaphragm center for raising the switching threshold of the tire pressure sensor (13) as a function of speed and is dimensioned in such a way that the switching threshold is raised by a desired pressure differential (.DELTA.p) relative to the switching threshold p.sub.o at standstill at a predetermined radius r of the diaphragm (21), a predetermined rotational radius R of the diaphragm (21) and a predetermined rotational speed v of the diaphragm (21). The required added mass (m) results from the equation m=f(.DELTA.p, r.sup.2, R, v.sup.2), advantageously m=(.pi./4)r.sup.2 {[R/v.sup.2 ].DELTA.p - p.a}k wherein p is the material density of the diaphragm, a is the diaphragm thickness and the factor k is between 1.1 and 1.5.

    • A pressure probe is suggested which serves to determine the air pressure in the interior of tubeless tires on motor vehicle wheels comprising a rim. The pressure probe (10) carries a substrate (26) in a front recess (31) of the probe housing (14) facing the tire interior, at least one sensing element (24) being arranged at the substrate (26) in the outer area on the side remote of the tire interior. In order to keep the air in the vehcile tire at a distance from the sensing elements (24) on the one hand, but transmit the air pressure to the latter without falsification on the other hand, a circumferentially extending cut out portion (36) in the housing area below the sensing elements (34) is filled with a non-conducting magnetic fluid (37), a permanent magnet (39) being arranged at the base (38) of the cut out portion (36), which permanent magnet (39) secures the magnetic fluid (37) for the purpose of covering the sensing elements (24) so as to be free of stresses (FIGURE).

    • The inductance of a variable inductor is put in series with a resistor to provide a delay circuit at the output of an amplifying path and the delayed voltage is fed-back to produce square waves having a period representative of the induct. The amplifying path includes a first amplifier and a final stage that includes a transistor. A second transistor is connected to a voltage supply line feeding the final stage and the delay network and is also connected to the final stage in such a way that the second transistor conducts when the first transistor of the final stage is blocked and so that the second transistor is automatically blocked when the output of the final stage is at a low potential. The base of the second transistor is connected through a resistance to a battery voltage line at a somewhat higher potential than that of the voltage supply line for the final stage. It is useful to provide an additional amplifier to operate the second transistor with its input coming from the feed back line supplied by the variable inductor and its network resistor, preferably through a low-pass filter. For adjustments that may be necessary when the inductor of a system is replaced, the characteristic curve of the evaluation circuit can be additively shifted by interposing a resistance-capacitance delay followed by an amplifying comparator in the amplifying path, preferably between the preliminary amplifier and the final stage.
