Abstract: The invention concerns a current-generating apparatus for supplying at least two probes designed to be applied to a part of the human body for the purpose of therapeutic treatment in the field of biophysics and physiology. This apparatus comprises a self-contained electrical power supply source (2) suitable for delivering a constant voltage, a constant current generator (18), a frequency-generator (10, 19) suitable for transforming the constant current so as to deliver a current in the form of biphase rectangular pulses with zero mean and steep edges, the total duration T of which in .mu.s is substantially between 200 .mu.s and 800 .mu.s, and a delay circuit (12, 14, 15) for delaying the sending of the starts of pulses suitable for triggering a pulse every k .times.15 ms, where k=1 or 4.

Abstract: A method and apparatus for regulating the flow and the temperature in a central heating installation including a heating circuit having a feed pipe (28), one inlet control and distributing unit (38), a plurality of heating coils (40, 40', 40"), one collecting unit (42) and a return pipe (24) with a circulation pump (25). The unit (38) comprises an inlet chamber (44) with an outlet for the respective coil, valves (46, 46', 46") for temperature control, one mixing chamber (48) with inlet tubes (58, 58', 58") from the inlet chamber (44) and outlet tubes (60, 60', 60") to the respective coils with temperature transmitters (50, 50', 50"). The inlet tubes project into the outlet tubes with intermediate gaps (61). From the return pipe a portion of the return water is recirculated to the mixing chamber (48) and via the gaps (61) into the outlet tubes.
