    摘要: 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).

    摘要: In a process for establishing the driving direction of a vehicle by an electronic compass fixedly mounted in the vehicle and which is provided with a magnetometer having a computerized evaluation circuit the local curve (O) of the earth field (He) is determined from five measuring points (M1 . . . M5) which are established by turning the vehicle and corresponding signals are stored. The parameters for the center point displacement (Hs), the shape (ellipse) and the turning (angle .alpha.) of the local curve (O) in the vector diagram (x,y) are calculated by the computer by means of an algorithm with five unknowns for the five measuring points and thereafter the direction of the earth field (He) is computed. Subsequently, the vehicle is oriented to a predetermined cardinal direction and a correction angle is determined from the difference of angles between the cardinal and north directions and the earth's magnetic field direction measured by the compass. In the subsequent measurements the correcting angle is then taken into consideration when establishing the driving direction (.phi.) from the local curve (O).

    摘要: A process for correcting inclination dependent angle errors when establishing the driving direction of vehicles with an electronic compass for navigation is suggested. The compass comprises a magnetometer (10) with an evaluation circuit (11) for computing the driving direction. For compensating inclination dependent angle errors on the indicator of the drive direction the inclination angle of the earth field is fed into the evaluation circuit (11) as a calibration dimension (E), subsequently the inclination angle (.psi.) of the vehicle is established cyclically by means of an inclination measuring device (12) and then the corrected driving direction (.theta.) is established from the computed driving direction (.theta.') as well as from the calibration dimension (E) and the angle of inclination (.psi.) in accordance with the equation .theta.=f (.theta.',.psi.,E). This corrected driving direction can then be further processed or issued to an indicator (13) (FIG. 1).

    摘要: 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.
