Driving apparatus for imparting linear reciprocating movement to a shear on a flying shear apparatus or the like. A continuously constantly rotatable axle is provided with a pair of disks having cam surfaces on the periphery thereof engageable with guide rollers fixed at two lever arms of a three-armed lever, the third lever arm being connected to the flying shear by way of a coupling rod pivotably attached at the third lever arm and the flying shear. The cam disks are configured so as to impart motion to the shear in a feeding direction with a first feed segment of increasing velocity, a second feed segment of constant velocity, and a third feed segment of decreasing velocity, whereby the shearing operation can conveniently be executed during the phase of constant velocity. The cam surfaces are so constructed that motion of the shear in the return stroke direction includes a first return segment of increasing velocity and a second return segment of decreasing velocity, without the interposition of a constant velocity section.

The present invention relates to control of a fan during which the power of the fan is determined from the characteristic curves of the fan motor, the operating parameters of the cooling system and the reference variables which are predefined in the form of temperature levels. The various temperature levels which are to be set have different associated characteristic curves for actuating the fan motor. If the reference variable for the control changes, this also means a change in the characteristic curves for actuating the fan motor. In order to prevent the fan motor from whining, the operation of the fan motor is kept constant for a settable minimum waiting time when the reference variable for the control of the fan changes. During this minimum waiting time, the operating parameters of the cooling system can, if appropriate, be adapted by means of other control mechanisms which are independent of the fan to the new reference variable to such an extent that it is no longer necessary to take measures with respect to the whining of the fan motor.

The invention relates to a fan run-on control which takes into account the energy input into the combustion engine in order to calculate the required run-on time of the fan. If the characteristics of the fan are known it is possible to calculate the required fan run-on time from the integral of the energy input into the combustion engine before the combustion engine was switched off, and the current operating data and ambient data of the combustion engine. Furthermore, by comparing the energy input into the combustion engine with the cooling performance of the cooling system over a specific period of time before the engine was switched off, it is possible to predict whether or not running-on of the fan will be necessary. There is always a risk of further subsequent heating whenever the energy input into the engine has been significantly greater than the cooling performance of the system before the engine was switched off. If the opposite is true, there may sometimes be no need for the fan to run on, or the fan run-on time can be much shorter than in previously known systems.

A method for setting the torque in an internal combustion engine determines a set air mass and a corresponding throttle valve setting from a set torque in a control tract. An actual air mass allows the difference between a set air mass and the actual air mass to be determined by comparing a set value and the actual value. The controlling effort for setting a desired torque will be reduced. A correction value for the difference between the actual and set values of the air mass is calculated whereby an adaptation of the control tract to the difference is performed. Thereby, in the control tract, a correspondingly adapted throttle valve position will then be associated with a set torque that is to be established. A compensation of the previously determined difference between the set value and the actual value of the air mass is produced. An actual fuel mass fed to the combustion chambers can be utilized for determining the actual air mass, as can a fuel/air mass ratio of a mixture fed to the combustion chambers.
摘要:
In a method for setting the output power of an internal combustion engine a resultant specified torque is determined from a driver-intended torque and at least tw o additional intended torques, and the resultant specified torque is set via a apparatus for adjusting torque. Each participant system, in addition to the intended torque, provides information regarding whether the intended constitutes a torque-increase or a torque-decrease. A processing block is provided for each participant system in which the particular intended torque is compared with the driver-intended torque and the resulting specified torque of the preceding participant system. From this, a resulting specified torque is determined. The priority of the particular torque requirement results from the sequence of the participant systems during processing.
摘要:
A device for evaluating periodic signals from inductive pick-ups compensates for the lag of the pick-up signal. This lag increases with increasing frequency as a consequence of the inductance of the pick-up, with respect to the position of a movable part that is to be scanned by the said pick-up. The relative time shift in the evaluation edge of the pick-up signal, which is phase-compensated via the frequency, is compensated for via changes in the amplitude of the pick-up signal.

An arrangement for generating mean-value-free binary signals includes a binarizing circuit which receives an analog signal to be binarized and binarizes said signal with respect to a binarizing threshold. Connected to the output of the binarizing circuit is a closed-loop control circuit which includes a differential integrator which receives at the one input the binary signal from the output of the binarizing circuit. Applied to the second input of the differential integrator is a desired value signal which corresponds to the mean value between the two signal levels of the binary signal. The differential integrator integrates the deviation between the binary signal and the desired value signal and furnishes a signal corresponding to the integrated deviation. By the signal corresponding to the integrated deviation the position of the analog signal relatively to the binarizing threshold is shifted in a sense such that the mean value of the deviation is regulated to zero. For this purpose either the signal corresponding to the integrated deviation can be superimposed on the analog signal prior to the binarizing or the binarizing threshold can be varied by the signal corresponding to the integrated deviation. Preferably, the desired value signal is produced by integration of a mean-value-free binary signal.
摘要:
A connecting element is provided for connecting together adjacent shuttering panels of the kind in which reinforcement strips with rows of holes provided therein are arranged at the edges of the shuttering panels and are dipsosed perpendicular thereto. The connecting element consists essentially of a curved lever arm (13) which tapers from a spigot part (17) to an end surface (18). The spigot part (17) adjoins a handle portion of the connecting element at a flange (16') defining an abutment edge (16). The handle portion is curved in essentially U-shaped manner and has a support surface (20) at the inside of its limb connected to the spigot portion (17). In operation the engagement end (18) of the lever arm is first introduced through two aligned holes in the adjacent reinforcement strips of two adjacent shuttering panels and the connecting element is then rotated about the abutment edge (16) so as to cause the spigot part (17) to enter into the two aligned bores. During this the lever arm clamps the two reinforcement strips together. In the engaged position shown in FIG. 2 the support surface (20) contacts one side of one of the connecting strips and the engagement surface (18) contacts the opposite side of the other reinforcement strip. The U-shaped handle of the connecting element has been pivoted downwardly so that the abutment end (12') thereof engages against the same side of the reinforcement strip (15') as the engagement surface (18). In this position the connecting element is reliably locked in place and the shuttering panels are reliably connected together.
