Abstract: In order to control a stepping motor, whose windings (1) are initially subjected to a first high, unstabilised voltage and then to a second low voltage (UM) during a motor step, the method provides that the windings (1) of the stepping motor are always supplied with a constant energy quantity, which is required for a motor step, while the first, high voltage (UM) is applied, by varying the application time as a function of the time response of the first high voltage (UM). In this case, it is assumed that the time response of the first high voltage (UM) can be used to derive a variable which is proportional to the energy quantity already supplied to the windings (1) of the stepping motor. <IMAGE>

Abstract: An improved method and apparatus for mixing fluid and/or granular substances, whereby greater mutual dispersion of at least two substances is achieved by attaining greater turbulence while minimizing the required amount of mechanical structure. Each of at least two substances is fed at a different angle in a belt-shaped stream to a nozzle, under pressures according to the viscosity of each substance. After initial mutual dispersion is achieved in the nozzle, the mixture passes to a mixing tube having a varying cross-section along its length, the varying cross-section creating further turbulence of the mixture passing through the mixing tube, causing further dispersion of the substances within the mixture.

Abstract: In a method for driving an asynchronous motor with speed control by means of a controlled inverter, the desired value of the phase difference between the motor voltage and the motor current is determined as a function of the frequency of the voltage supplied by the inverter. The amplitude of the voltage supplied by the inverter is controlled to make the actual value of the said phase difference equal to the desired value at the frequency at issue. The desired value function is determined on the basis of the desired value given for the individual motor at nominal frequency and by means of the equivalent diagram of the motor. A device for carrying the method into effect comprises a detector (7) for determining the actual value of the phase difference between the motor voltage and the motor current, a comparator (8) for determining the difference between said actual value and a desired value of said phase difference, said desired value being a function of the frequency of the voltage supplied by the inverter, and a control unit (10) actuated by the difference between said actual value and said desired value, for controlling the amplitude of the alternating voltage supplied by the inverter toward equality between said actual value and said desired value at the frequency at issue.

Abstract: The laser sight is optically aligned in an alignment unit, causing a comparator (15) to be rotated, the output signal (16) from which activates a motor (17) via an amplifier (18) so that the signal remains zero. The motor alos rotates a camera (9) via a mechanical transmission, symbolised by a gear train (19,20). The camera rotation is monitored by a further comparator (21) which forms a difference signal (22) which with perfect mechanical transmission is of the same size as the difference signal from the first comparator, i.e. very close to zero. The camera produces a picture of the target (23), very muck like a television picture, i.e. a signal sweeping in an angular direction, combined with a signal which indicates the picture light strength. In a further device (24) fault signals are added to the sweep movement, the device incorporating an oscillograph tube (25). This tube is combined with the laser sight, and the aimer of the weapon can no observe the target, either with the optical channel (5) or with the display.

Abstract: The battery charger connected to the battery drives a pulsed charging current through the battery cells with a current supply part ('on' time) and a non-current supply part ('off time). The method involves adjustment for a max. charging voltage for the battery and during the subsequent pulse sequence the total pulse length is unaltered with the current fed during the 'on' time exceed an average current calculated for the battery. During the 'off' time for each pulse, two separate voltage measurements are carried out, of which the first corresponds to the battery voltage without influence from the effective direct resistance (Rh), whilst the second corresponds to the battery voltage with regard to the effective delayed resistance (Rp). Starting from the received measurement values, the pulse on-time/off-time is determined so that the charging voltage with high precision is continuously controlled as close to the permitted max. charging voltage as possible.

Abstract: A sensor for three dimensional detection of the position of a ball joint 1 in which two emitters 14-15 and two collectors 20-21 are located in the ball 4 and socket 5, respectively, of the ball joint 1, and at least one more emitter or collector is located in either the ball 4 or socket 5. Each of the emitters emits a unique signal characteristic and each of the collectors detects and decodes the signals from all emitters. By analyzing the influence of all the emitters on each of the collectors, the position of the ball joint can be deduced. The emitters can be coils or light emitting diodes that emit unique signal frequencies and the collectors can be coils or photo transistors which detects the ratio of signals from each of the emitters. Alternatively, a rotating magnetic field can be induced by three emitter coils in one of the joint halves and detected by three collector coils located in the other joint half.
