  • Patent number: 11925479
    Abstract: The present invention relates to a method of determining the body temperature or a temperature correlated therewith of a patient connected to an extracorporeal blood circuit, wherein the extracorporeal blood circuit has a heat exchanger which is flowed through by blood at one side and by a heat carrier medium at the other side, wherein the temperature (Tdi) of the heat carrier medium at the inlet side is measured at the inlet of the heat exchanger and the temperature (Tdo) of the heat carrier medium at the outlet side is measured at the outlet of the heat exchanger and the volume flow of the heat carrier medium (Qd) is measured; and in that the temperature (Tbi) of the blood at the inlet side is determined at the inlet of the heat exchanger in accordance with the relationship Tbi=Tdi (Qd/D) (Tdo?Tdi), where the value D is a value characteristic of the heat transfer by the heat exchanger.

  • Patent number: 11858021
    Abstract: A control device (3b) for a roll stand (1). During rolling of a metal strip (2) in the roll stand (1), the device receives measurement data (M) for a lateral position (y) of the metal strip (2) on the inlet side and/or outlet side of the roll stand (1). Taking into account parameters (P) of the stand regulator (3a) on the basis of the deviation in the lateral position (y) from a target position (y*), a stand regulator (3a) of the control device (3b) determines a tilt value (?s) for the roll stand (1) and controls the roll stand (1) accordingly. The control device (3b) determines at least one variable (V1, V2, Q1, Q2) from which it is derived, for both strip edges (7, 8) of the metal strip (2), whether the metal strip (2) forms an undulation (9) in the region of the particular strip edge (7, 8).

  • Publication number: 20230271238
    Abstract: A method for operating a storage device for two rolls in a roll stand for rolling metal. The storage device is component part of the roll stand or can be positioned relative to the roll stand so that the rolls can be transferred from the roll stand into the storage device or vice versa. A measuring system is provided which detects the temperatures and/or the diameters of the rolls individually and independently of one another, at least at predefined detection positions, as viewed in the direction of the roll axes. After transmission to an automation unit that controls the roll stand, the unit can adapt a roll model, by means of which it repeatedly determines the temperatures and/or the diameters of the rolls, at predefined determination positions, in the direction of the roll axes, using operating data of the roll stand for the rolls of the same type.

  • Patent number: 11596725
    Abstract: The invention relates to a device for extracorporeal blood treatment, comprising a blood treatment unit 1 that comprises at least one compartment 4. The invention further relates to a method for determining a hemodynamic parameter during an extracorporeal blood treatment by means of an extracorporeal blood treatment device. In order to determine the hemodynamic parameter, the conveying direction of the blood pump 10 is reversed from a “normal” blood flow to a “reversed” blood flow. In practice, it has been found that reversing the conveying direction of the blood pump for a measurement for determining a hemodynamic parameter carries the risk of blood clots reaching the patient, despite the dialyser holding back blood clots. The blood treatment device comprises an input unit 23 for inputting a time interval which can be specified by the user, taking into account the patient-specific and system-specific factors.

  • Patent number: 11364526
    Abstract: A metal strip is rolled in a roll stand and a control device for the roll stand determines, by means of a working cycle, a number of manipulated variables for flatness actuators of the roll stand and actuates them accordingly. The control device implements an optimizer, which provisionally sets the current correction values, and determines a totality of flatness values. Then, the optimizer minimizes the relationship by varying the current correction variables. When determining the current correction variables (s), the optimizer considers linear ancillary conditions, based at least in part on a vector having the ancillary conditions upheld by the current correction values and a vector having the ancillary conditions upheld by the difference of the current correction values relative to the correction values of the preceding working cycle. The control device determines the manipulated variables for the flatness actuators in consideration of the determined current correction variables.

  • Patent number: 11324868
    Abstract: The invention relates to an apparatus for extracorporeal blood treatment, comprising a blood treatment unit 1 that comprises at least one compartment 3. The invention further relates to an apparatus 15A, 15B for collecting blood clots for a blood line 5, 7 for supplying blood to or removing blood from a blood treatment unit 1 of an extracorporeal blood treatment apparatus, and to a method for determining a hemodynamic parameter during extracorporeal blood treatment using an extracorporeal blood treatment apparatus. In order to determine the hemodynamic parameter, the conveying direction of the blood pump 10 is reversed from a “normal” blood flow to a “reversed” blood flow. It has been found in practice that, in the event of a reversal in the conveying direction of the blood pump in order to carry out a measurement for determining a hemodynamic parameter, there is a risk of blood clots reaching the patients, although the dialyser traps blood clots.

  • Patent number: 11294338
    Abstract: An automation system (1) determines control data (S?), outputs same to controlled elements (5) of the facility (ANL) and thereby controls the facility (ANL). Sensor devices (2) acquire measurement data (M) of the facility (ANL) and at least partly feed same to the automation system (1) and a man-machine interface (3). Said man-machine interface (3) receives planning data (P) from a production planning system (11) and/or control data (S?) and/or internal data (I) from the automation system (1). The interface outputs the data (M, S?, I) to a person (4). It furthermore receives control commands (S) from the person (4) and forwards them to the automation system (1). The automation system (1) processes the measurement data (M) and the control commands (S) when determining the control data (S?). An artificial intelligence unit (9) receives at least part of the measurement data (M), control data (S?) and/or internal data (I) and the data output to the person (4). It also receives the control commands (S).

  • Patent number: 10780474
    Abstract: A metal band is first rolled in a front and then in a rear (downstream) roll stand of a multi-stand rolling train. A looper between the roll stands may detect a band tension in the metal band. The band tension is supplied to a first and a second tension controller to determine an application additional target value and a speed additional target value. The second tension controller may only determine a value less than or greater than 0, as the speed additional target value, if the band tension is above or below an upper or lower band tension limit. Otherwise, the speed additional target value may be 0. The first tension controller is also supplied with a target tension that falls between the band tension limits. The application additional target value may be used to act on the rear roll stand.
