Abstract: The invention concerns equipment for bricklaying of prefabricated chimneys and comprising a stationary frame construction 2,3,4,6. In order to enable bricklaying of the chimney to be carried out from one and the same position at a convenient working height, without the need to build scaffolding, work on roofs, etc., the frame construction forms a vertical guide 4 for an upward/downward movable operating frame 5 with carrier arrangement 14 for the chimney elements which are to be laid one at a time against the above-lying element or several elements A5-A8 laid together, and raised a vertical distance corresponding to a full element height at each lift. The stationary frame construction is provided with a side frame 6 at a convenient working height above the chimney's lower end. The side frame 6 comprises mainly horizontal slide rails 7 which extend into the area of the upward/downward moving element carrier 14, so that a chimney element A4 which is arranged on the side frame's support surface for the application of mortar onto its upper side, possibly lying on a thin slide plate 8, can be moved along the slide rails 7 to a position where it will lie beneath chimney element A5 or several elements A5-A8 situated above so that, by lowering the element carrier 14, it can be laid together with the said above- situated element or several elements respectively. In this position, the element carrier 14 is arranged so that it can be opened and then lowered alongside the mortar- coated element 4 which has been fed in from the side frame 6. After that, the element carrier 14 is closed beneath the said element A4 and, supporting this element and the above-situated chimney elements already laid together, the carrier 14 is raised a vertical distance corresponding to a full element height, after which the said procedure is repeated until the required chimney height has been attained. <IMAGE>

Abstract: Method and device for controlling an AC induction motor at all speeds of the motor including zero speed. The supply voltage is modulated with a sine-shaped signal with a predetermined frequency in order to generate a stator magnetic field and a rotor current. The supply voltage (uS) is distorted so that the magnetizing portion of the voltage (VL) will be sine-shaped. If this condition is fulfilled, compensation is achieved for such errors as the nonlinear magnetizing properties of the iron at beginning saturation and further sources of moment ripple is eleminated. The invention relates to voltage control of the induction motor in spite of the fact that the torque is generated by the current through the windings. The distortion of the voltages can take place in different ways and sine and cosine tables with adjusted values are described. A complete mathematical analysis of the motor model of the AC induction motor is given including the stator and rotor leakage inductances.
