Title: Control circuit for underfloor electric heating - has programmed heating with correction for external conditions and for thermal variations
Inventor: WALTER ULRICH PROF DIPL ING
IPC: F24D19/10
Filed: 1990-03-15
Abstract: The programmed heating control includes the preset room  temperature, the outside temperature and the starting temperature of the heating block. The required heating effect is computed and applied at the start of the heating sequence. The actual rise in temperature is compared with the programmed value and any deviations are compensated for. In this way the effects of any thermal heat sinks, positive or negative, are corrected for. The heating period is divided in set smaller periods, to enable the control system to monitor the effects of the heating periods.  A central controller can regulate the heating of several rooms, and also split the electric load for even demand. ADVANTAGE - Improved heating control, improved  comfort, less variation due to external influences.

Title: Induction motor rotary speed control - uses coil reversal according to working programme and loading momentum to align motor currents
Inventor: SCHAEFFERSMANN HEINZ
IPC: H02P27/048
Filed: 1991-06-17
Abstract: To control the rotary speed of induction motors by frequency converters, in machines and vehicles where torques of different levels are required, the motor currents are aligned by reversing the coil according to the working program and loading momentum. The coil is in more than two grooves, for each pole and phase, with a higher number of rotor grooves than stator grooves. The coil is a chord semi circular winding. To minimise the current, the working motor coil is selectively switched in series or parallel by the power electronics together with different running and acceleration speed ramps. The programmed reverse or switch-on circuit for working also contains the programming for the frequency converter with internal or external programming to give a direct or indirect reverse of the motor working coil according to the current voltage and/or frequency value. The meter, to measure the voltage or current or power, has an outlet to reverse the working coil with a time delay. The unit or reverse for the working coil is an integrated component of the frequency converter. ADVANTAGE - The system reduces the energy consumption, using small motors and frequency converters, which also cuts noise.
