Patent DE-2920167-A1 (DE)
Title: Miniature motor speed control for toys and models - uses control pulses of regularly varied width or spacing, or both
Inventor: FREIER WOLFGANG ING GRAD
IPC: H02P27/02
Filed: 1979-05-18
Abstract: The control system for miniature electric motors for model railways and similar toys, uses rectangular pulses of the same amplitude instead of conventional phase or amplitude control. The width of the pulses varies with the speed required, and corresponds to the required interval between pulses. Either the duration of the pulses, or the time between pulses, or a combination of the two is altered in a regular manner to change the speed. These values can be altered between zero and 100%. They can be varied by a reference frequency, and the pulses can be positive or negative. An amplitude control can be combined with pulse control, and can be operated manually.

Title: Electromagnetic force compensation balance - provides order non-linearity correction using correction coil non-linear current supply controller
Inventor: EXNER RAINER
IPC: G01G7/04
Filed: 1979-07-17
Abstract: An electromagnetic balance with force compensation has a permanent magnet system (2) with a force compensation coil (9) projecting into its air gap and connected to the moving load sensor. A correction coil (17) fixed in the permanent magnet system corrects the effect on the magnetic field of the compensation coil (9). It has an adjustable temp. independent linearisation circuit of a simple design with the ability to correct for non-linearities of high order. A current source controlled according to the current in the compensation coil provides the current for the correction coil. The current source control voltage is taken from across a measurement resistor (14) carrying the compensation coil current. The current provided by the source varies non-proportionately with the control voltage.

Title: Leak testing by differential pressure measurement - using controlled displacement body regulating pressure difference between comparison volumes
Inventor: KLEE GERHARD
IPC: G01M3/32
Filed: 1979-07-26
Abstract: A differential pressure measurement device has two comparison volumes which can be connected to its two measurement chambers. In partic. it is a leak tester with a test object connected to one chamber and a reference object to the other. It gives a quantitative unambiguous leak measurement on faulty test objects such as fuel tanks by simply performing accurate differential pressure measurements. A pressure difference between the measurement chambers arising from a pressure change in the comparison volumes is compensated by varying one or both volumes using a displacement element controlled by the difference pressure. The pressure difference thus remains practically constant during the measurement and the comparison volume, conditional change is measured indirectly from the compensating element, e.g. a piston, displacement.

Title: Common source load feeding system - supplies pulsed voltage each being regulated for amplitude and length using RMS value regulator
Inventor: GRETSCH RALF DR ING
IPC: B60T13/14
Filed: 1980-10-01
Abstract: In the system for feeding loads e.g vehicle battery and lamps connected to a common voltage source, which have different voltage or current requirements, the arithmetical average value (U bar) or peak value and the r.m.s value (U) of the supply voltage are regulated differently whilst maintaining the electrical connection between the voltage source and the individual loads. For this purpose, the supply voltage is produced in a pulsed manner, the pulse amplitudes and pulse lengths being regulated individually. An r.m.s value regulator (1a) determines the magnitude of the output voltage, and an arithmetic average value regulator (1b) determines the relative 'on' period of the output voltage. When applied to the electrical system of a motor vehicle fed by a three-phase generator, the r.m.s. value regulator acts upon the field winding of the generator, while the average value regulator triggers thyristors connected to the stator windings with a predetermined frequency and variable duty ratio.

Title: Tyre-pressure monitoring system for vehicle - has free-running oscillator coupled to evaluator circuit
Inventor: HAUBNER GEORG
IPC: B60C23/04
Filed: 1980-10-06
Abstract: The monitoring system has a free-running oscillator (15) near the wheel being monitored. The oscillator's output is coupled via a capacitor (25) to several parallel indentical RC circuits (26,27) containing grounded capacitors. The connections between the capacitors and the resistors in the RC circuits are coupled to an evaluator (32) and via a line (33) to the grounded induction coil. The capacitor in each RC circuit forces resonant circuit with the induction coil whose frequency is the same as that of the filter (37) and the oscillator. The advantage lies in being able to locate the induction coil away from the main circuitry.

Title: Electrostatic solvent-free pigment coating - guiding air flow over workpiece vertically downwards, with acceleration below working zone
Inventor: BERKMANN ADOLF
IPC: B05B16/00
Filed: 1980-11-12
Abstract: The pigment particles, not sticking to the coated workpieces, are entrained in an air stream and removed from the surrounding environments. Then the pigment particles are reclaimed from the air stream and supplied to the particle circuit. In the work zone, e.g. a spray cabin, the air stream is guided vertically downwards and accelerated underneath the cabin. Then the pigment particles are completely filtered out from the air stream. After admixture of fresh air the filter air stream is returned to the cabin after an air conditioning process concerning temp. and humidity. The air stream is pref. blown in uniform distribution over the entire paint spray cabin. After leaving the cabin the pigment-air mixture is first coarsely separated by centrifugal acceleration, followed by complete separation by a filter.
