Abstract: Control for use in an automation system, including a processor having a communication port for a communication with a sensor and for a reception of sensor signals and a control port for providing control signals, a supply connected to the control port and adapted to provide a variable electrical supply voltage at a supply port in dependence on a control signal level of the control signal, wherein the communication port, the communication port and the supply port are connected to an interface adapted for electrical connection to a sensor, wherein the processor is adapted for providing at least two different communication protocols at the communication port and for providing at least two different control signal levels at the control port.

Abstract: A method for operating a multi-limb manipulator which includes electric actuators assigned to manipulator limbs, control units assigned to the actuators, including: the provision of desired movement values for the actuator to an actuator dynamic model and the determination of an electric desired current value for the actuator, the transfer of the desired current value to a controller designed for outputting an actuator current to the actuator with the inclusion of the desired current value and of a measured actual current value and a measured actual position of the actuator, wherein a difference between the desired current value and the actual current value is determined as a required positional deviation, and wherein the positional deviation is added to the desired distance fed into the actuator dynamic model to facilitate a diversion movement of the manipulator limb operated by the actuator on the occurrence of an external disturbing force.

Abstract: A linear drive device has a stator and an armature able to be moved in relation to the stator in a linear manner. The device furthermore comprises an electrodynamic linear direct drive system and a fluid power drive system. Using the two drive systems it is possible in an independent manner for setting forces to be applied electrodynamically and by fluid power to the armature.

Abstract: A method of producing gas concrete. Water, lime, cement and sand are pre-mixed. A calcium sulphate-containing component is subsequently mixed in and a rising agent is later admixed to form a castable mass suitable for making gas concrete by the conventional steps of pouring into a mold, permitting the mass to rise and harden sufficiently to be cut to size, and hydrothermally cured. By following the indicated procedure for making the castable mass, the calcium sulphate-containing component can be advantageously used.

Abstract: A method of producing gas concrete. A castable mass is prepared by mixing water, a lime component including lime having a t.sub.60 value of less than ten minutes, and a sand component. A calcium sulphate-containing component is subsequently admixed and a rising agent, such as aluminum powder, is subsequently admixed. The mass thus prepared is cast into molds and fabricated into gas concrete by the conventional steps of permitting the mass to rise and harden, cutting the hardened material to size, and hydrothermally curing. The process makes possible the use of readily available inexpensive lime material without the disadvantages normally resulting from use thereof.
