Abstract: The method of regulation employs a simulation process for at least one state variable of an apparatus to be controlled and regulates the state variable. In the process, a curve of an operating characteristic having its base at an idle state value is traversed up to an operating state value. When re-regulating, the regulation process begins at the current value of the state variable. The value of the regulation variable corresponds to the idle state. This has the advantage of a defined initial point for re-regulation. A regulating device for performing the method of regulation comprises a series circuit containing an input circuit, a regulation circuit with a simulation device for regulating an apparatus as well as a control circuit for possible machines coupled to the apparatus. The simulating device is adjustable according to operating characteristics or apparatus parameters. Another regulating device fulfills the same function while employing a computer and correspondingly modified circuits.

Abstract: Process and apparatus for manufacturing multi-part forms uses web presses having printing stations and processing stations at which operations are performed on webs in registry with a series of printed images, and uses a collator to assemble related webs from said presses, and to perform additional operations on assembled webs in registry with images thereon. A digital job description of a form is created, including location of printed images on several parts of the form and location of process items, e.g. perforations, holes, or cuts on parts of the form. This job description is stored in the memory of a computer [PR-2] with a job identifying code. Also, a digital description is created of images to be printed on the form, and stored in memory with the job identifying number. The image descriptions are recalled from memory and used to create printing plates for the presses and to pre-set printing and processing sections of a press for each part of the form.

Abstract: A magnitude signal representing the approximate magnitude of a control parameter vector for the control of multi-phase electrical apparatus is developed from the Cartesian coordinate signals of the vector. Signals representing one or both coordinates of a plurality of auxiliary vectors are formed by vector rotation coordinate determination techniques. The signal from among the auxiliary vector coordinate signals (and, optionally the control parameter vector coordinate signals) having the greatest absolute value is selected as the magnitude signal. Auxiliary vector coordinate signals are formed by proportional stages coupled to adder stages which combine specified constant proportions of the control parameter vector coordinate signals. A diode network provides biasing so that only the signal with the greatest value will be passed. The auxiliary vector forming method for vector magnitude approximation provides accuracy and simplicity.
