摘要:
A method for determining the steering ratio of a vehicle from sensed measured values (e.g., yaw rate, steering wheel angle, vehicle speed) in a manner that takes vehicle parameters (e.g., self-steering gradient, wheelbase and other vehicle dimensions) into consideration during stable travel of the vehicle.

A connection between a plate and a pipe wherein the pipe passes through an opening in the plate, and wherein the plate has a spring-elastic tongue at the opening which is fixedly connected to the pipe.

According to the invention, a process for the rectification of mixtures of high-boiling air- and/or temperature-sensitive substances which require a high separation efficiency is proposed, in particular a process for the working-up of a VE- or VEA-containing product stream. The process is characterized in particular in that, in a first purification stage, low-boiling products and unspecified isomers of the useful product are separated from the product stream virtually without loss of useful product and that, in a second purification stage, the useful product is removed in a stream having a purity of >97% by weight and a further stream having a purity of >92% by weight. A preferred embodiment of the process serves for working up VEA, in which the loss of useful product in the first purification stage is less than 5%, based on that amount of VEA in the feed which is added to the purification stage per unit time. Furthermore, the first purification stage may comprise a rectification column (1), from the top (Ia) of which the low-boiling products and the unspecified isomers of VEA are taken off, a stream containing the useful product in purified form being taken off at the side (15) and/or at the bottom (Ib) of the column (1).

A method is described of determining the distance (50, 56) of a projection point (24) of a first imaging beam (22) of imaging device (20) from a measuring point (28) of a measuring device (26) or from a second projection point (36) of a second imaging beam (34) of a second imaging device (32) on the surface (10) of a printing form (12), both the projection point (24) of the first imaging beam (22) and the measuring point (28) of the measuring device (26) or the second projection point (36) being movable in relation to the surface (10) of the printing form (12). In the method, the reflected light intensity of at least a part of a pattern (84), which is produced by the first imaging beam (22) on the printing form (12), is measured as a function of the position of a measuring device (26), so that the distance (50, 56) may be formed as the difference of the position of the measuring device (26) and the correlated position of the imaging beam (22), at which the imaging beam (22) was located when the part of the first pattern (84) was written. The method may advantageously be used in a method of correcting the time triggering of an imaging beam (22), using which a projection point (24) may be produced on a surface (10) of a printing form (12).

摘要:
An imaging device (10) for a printing form (12), in particular in a printing unit (82) of a printing press (84), having at least one light source (14) and an imaging optics (18) for projecting the at least one light source (14) onto the printing form (12), at least one optical element (20), in particular a lens, of the imaging optics (18), being movable by way of an actuator element (48), and the imaging optics (18) including one sensor (24) for measuring the actual position of the optical element (20), the sensor having one coil (26) and at least one sensor target (28). The sensor (24) is assigned to a control element (66) for adjusting the position of the optical element (20) via the actuator element (48), so that a highly precise, dynamic positioning of the optical element (20) can be achieved.
摘要:
A control method for generating a manipulated variable for controlling a hydraulic drive. In this case, account is taken of at least a desired value for the speed of the hydraulic drive, a first parameter, which simulates the response characteristic of the hydraulic drive, and a second parameter, which simulates the internal resistance which the technical process, opposes to the hydraulic drive. It is advantageous that nonlinear dependencies of the hydraulic drive can be taken into account for generating the manipulated variable driving the hydraulic drive. A technically complicated sensor system may be dispensed with. The control method may serve, in particular, the nonlinear control of a plastics injection molding machine.
