Abstract: A method of setting a temperature control system, in particular a hot water heating system, having a plurality of heat transfer devices through which a heating or cooling agent flows, includes the following steps: establishing a heating or cooling agent volume flow value for each heat transfer device with the specification that each object to be temperature-controlled is to experience the same specific energy supply; and adjusting the volume flows to the established values. A device for carrying out this method is also included herein.

Abstract: A device (1) for machining by turning rotationally symmetrical surfaces (18, 20 or 22) of a workpiece (10), which is clamped and has a rotating drive, including a tool (12) having two cutting edges (16) and (17), each having an approximately helical shape, which are disposed one behind the other in the feed direction of the tool (12) such that after the machining by turning with the first cutting edge (16), a roughing edge, the second cutting edge (17), a finishing edge, comes into engagement.

Abstract: To produce rotationally symmetrical surfaces of a workpiece (10), the rotationally driven workpiece (10) is subjected to rotational machining. For this purpose, a tool is used (12), whose blade (16) is advanced in a circular arc motion (f). The blade (16) takes the form of a coaxial helix in relation to the rotational axis (A1) of the tool.

A device for carrying out this method includes: a temperature control system having a source of heat or a heat sink, and a plurality of heat transfer devices through which a heating or cooling agent flows, a valve or a throttle device being provided for each heat transfer device for influencing the inflow of the heating or cooling agent; and a central evaluation/control unit with the aid of which the valves or throttle devices are adjusted to volume flow values of the heating or cooling agent.

Abstract: A smart control strategy/system for regulating a temperature controller for supplying or exhausting heat to/from a room, object or the like. The actual temperature of a room, object or the like requiring temperature control is prompted to dither between a specifiable maximum and specifiable minimum temperature setpoint by signaling the temperature controller periodically on/off. The profile of the actual temperature is continually monitored and the changes in the profile of the actual temperature resulting as a reaction to ON/OFF of the temperature controller are made use of to determine optimum ON/OFF points in time of the temperature controller.
