Patent DE-3339070-A1 (DE)
Title: Circuit arrangement for monitoring and for the sequence-controlled switching on and off of power supply units
Inventor: KNUTH MANFRED
IPC: H02J9/00
Filed: 1983-10-28
Abstract: The subject-matter of the invention is a circuit arrangement for monitoring and for the sequence-controlled switching on and off of power supply units in the event of voltage reductions or failures. The supply voltage for the power supply units (49, 50, 51) is monitored at a lower limit, and a warning signal is produced if the voltage falls below this limit. The warning signal causes an alarm signal for the duration of a delay time which depends on the supply voltage dropping below a specific threshold value, said supply voltage being buffered by an energy store. After the end of the delay time, cut-off signals are produced for the respective power supply unit and for further power supply units which are jointly arranged with said unit in a monitoring loop. Once the supply voltage is re-applied to the power supply units (49, 50, 51), the output DC voltages are tested after a time which can be predetermined. If at least one of the output DC voltages deviates from the desired value, the respective power supply unit is cut off. <IMAGE>

Patent DE-3416181-A1 (DE)
Title: Energy generating system
Inventor: SCHAEFER WOLFGANG DR ING
IPC: C10J3/54
Filed: 1984-02-28
Abstract: The invention relates to an energy generating system with a fixed bed pressure reactor, in which coal is gasified, with a gas-heated steam generator connected on its output side, the steam from which drives a steam turbo generator set and the supercharged flue gases of which drive a gas turbine generator set, and with a device for purification of the gas coming from the fixed bed pressure reactor. This device has hitherto been a wet cleaning plant, which among other things has the disadvantage that the temperature of the gas is greatly reduced, thereby causing large energy losses. By contrast, the invention proposes to form this device from one or more cyclones and thereby to perform dry cleaning, which ensures essentially less cooling of the gas and at the same time permits direct further use of the dry dust by returning it to the inlet side of the fixed bed pressure reactor. The system thereby affords good overall efficiency and can function cost effectively.

Title: Automatic reversing control for passenger cars with trailer
Inventor: SCHERBER KARL
IPC: B62D13/06
Filed: 1984-08-16
Abstract: In order to simplify the difficult operation of steering a passenger car with trailer in the reverse direction, the complicated actual steering is effected completely automatically with the required countersteering technology whilst the manual steering which is to be carried out with a small control potentiometer is converted into the very much easier set-value steering and, by way of comparison, on a remote controlled model vehicle with the same steering technology can even be carried out by a child without the trailer ever being able to leave its predetermined reversing route or even jack-knifing. The steering transmission is effected by means of an electrically controllable power steering or auxiliary servodrive and the approximately fist-sized electronic system is fed from a plurality of potentiometers which act as angle value transmitter and control potentiometer. The total stabilisation of the trailer reversing route is essentially achieved with an electronic countercoupling of the trailer shaft angle onto the steering wheel angle.
