The pump arrangement further has an intermediate reservoir and a second pump, which are connected in series together with the first pump in the first flow path, wherein the intermediate reservoir is fluidically arranged between the first pump and the second pump. The disclosure further relates to a cannula arrangement for a heart support system of this kind and a corresponding use of the heart support system.

Abstract: The invention relates to a method for adjusting at least one control parameter (KP) of an internal combustion engine (200) by means of at least two setting parameters (SP), having the following steps: determining an optimum steady-state combination (110) of the at least two setting parameters (SP) in order to obtain the setpoint value (104) under steady-state boundary conditions, producing a functional dynamic relationship (120) between the control error (100), a setting expenditure (130) for the at least two setting parameters (SP) and the determined steady-state combination (110), optimizing the dynamic relationship (120) in order to determine an optimum dynamic combination (140) of the at least two setting parameters (SP), and using the optimum dynamic combination (140) for the following adjustment step during the adjustment of the at least one control parameter (KP).

Abstract: In one embodiment of the present invention, a method and device are disclosed for the transport of goods by rail, wherein goods wagons are used with independent propulsion means. The propulsion means for the goods wagons are used only for short journeys from a station to a customer and back. For long journeys the goods wagons are assembled into a train and pulled by a tractor vehicle.

Abstract: The invention relates to methods and devices for developing programs for process control systems and in particular for mathematically intensive or, as the case may be, mathematically complex programs of said kind. According to the prior art programs of said kind were written in a separate development environment and subsequently the developed algorithm was re-implemented using a programming language available for the process control system and the associated compiler. The programming and testing were consequently both time-intensive and prone to error. It is proposed to split the overall algorithm into two parts when programming programs of said kind, a) the actual control algorithm by means of which the mathematical functionality of a controller is provided, and b) the algorithm by means of which the process control system-specific functionality of the above controller is provided.

Abstract: The invention relates to a method for the control of the chain drive mechanisms of underground working machines and a correspondingly equipped chain scraper conveyor. The invention proposes to filter out a detection signal (Serk), representative of the currently arising vibrations of the chain (1), from the operating data of the main and auxiliary drives (I, II) by means of a detection device (34), and to take this to an active suppressor (35), which generates a time-variable control signal (STilgung) in accordance with a suppressor function, with which, in the frequency range of the vibration of the chain, a change is effected to a control value, e.g. (Ssoll) for the closing pressure adjustment of a multiple disc clutch (6) of at least one drive unit for the suppression of vibration by the abstraction of energy from, or the introduction of energy into the chain (1).

Abstract: The invention relates to a method for the control of the chain drive mechanisms of underground working machines and a correspondingly equipped chain scraper conveyor. In chain scraper conveyors with a large distance between the main and auxiliary drive stations, e.g. a distance of more than 400 m, a chain breakage in the bottom run or a shaft breakage can arise, which can be traced back to vibration phenomena in the chain. The invention proposes to filter out a detection signal (Serk), representative of the currently arising vibrations of the chain (1), from the operating data of the main and auxiliary drives (I, II) by means of a detection device (34), and to take this to an active suppressor (35), which generates a time-variable control signal (STilgung) in accordance with a suppressor function, with which, in the frequency range of the vibration of the chain, a change is effected to a control value, e.
