Abstract: The invention relates to a method and means for determining the position of an elevator car on the principle of floor selection by means of a pulse train, whereby the position of the elevator car is determined on the basis of a pulse count indicating the elevator's speed. The achieve a more reliable pulse count based floor selection system which is suited for use with any type of elevator, the pulses required for calculating the elevator position for floor selection are obtained from an acceleration sensor placed on the elevator car, the output signal of which is integrated so as to obtain a voltage representing the speed of the elevator car, said voltage being converted into a pulse train whose frequency is dependent on the speed of movement of the elevator car.

Abstract: A capacitive safety system for controlling a door, e.g. an elevator door, so as to automatically avoid obstacles, employs electronic control for antennas operating as capacitive measuring elements for establishing shield voltages of identical phase on the antennas and on shield voltage antennas to counteract ambient capacity variations. In order to improve the operation and safety of the elevator door, the elevator shaft door, which closes simultaneously with the elevator door, is provided with similar capacitive measuring antennas and electronic controls as the elevator door, as well as with similar shield voltage antennas, which operate on a shield voltage having the same phase as that of the elevator door. Operation of the elevator shaft door and the elevator door with identical phases is effected by means of a wireless shield voltage transfer unit.

Abstract: A method and apparatus for switching thyristor bridges in converting alternating current statically to direct current by the aid of two thyristor bridges connected in parallel so that a direct current machine consuming direct current will receive both positive and negative current. One and the same analog voltage controls both thyristor bridges so that when the controlling analog voltage is positive the first bridge is open and when the controlling analog voltage is negative the second bridge is open, and that as the circuit approaches zero-current state the bridges shift to a reciprocally oscillating mode of operation.

Abstract: The invention relates to an elevator comprising an elevator car unit containing at least two elevator cars and to a procedure for controlling the elevator. According to the invention, at least one elevator car can be moved vertically within the elevator car unit relative to its frame. The procedure is characterized in that prior to start-up, the exact distances between landings are measured and stored in memory. The distance data corresponding to the control instruction according to a unit call or car call is then determined, and based on this data, the elevator car unit is caused to move in the shaft to a position corresponding to the call. At least one of the elevator cars is caused to move relative to the frame of the unit to a position corresponding to the distance between the floors in question.

Abstract: A method of and apparatus for regulating the control voltage of a three-phase inverter supplying an a.c. motor are provided, the inverter having a power stage implemented with semiconductor switches, and the output voltage of each inverter phase being measured in the voltage control. For rapidly improving the curve shapes of the inverter output by means of feedback, the control voltage of the pulse width modulator of each inverter phase is regulated by a voltage regulator. The control voltage obtained as output of the voltage regulator is derived from an actual value voltage formed from the output voltage of each inverter phase and a reference voltage.

Abstract: The invention concerns, first, a signalling procedure for a lift, whereby the control system and the users of the lift are informed on lift calls and the state of the lift, e.g. position, movement and availability, by using serial communication between the control system computer and the actuating and signalling means in the lift car and on each floor level, and, second, a signalling system applying the said procedure. To avoid abundant and complicated wiring and to increase standardization in the design of the lift system main panel and call button stations, the signalling system of the invention employs the polling principle in its internal communication, whereby data are transmitted bi-directionally using digital series loops, one of which connects the devices in the lift car, controlled by and communicating via a microprocessor, another connects the corresponding shaft and door devices, while a third loop is used for communication with the external world.
