Abstract: A pulse floor selector for a lift, with a floor and location determining system based on counting pulses indicating the lift's velocity, with the aid of electronics thereto appropriate. Dense pulse floor selection is used for determining the lift's location, in particular in modern high speed lifts. To serve as pulse former, generally a pulse transmitter (PA) mechanically coupled with the motor is required, which supplies a number of pulses (PT) proportional to the distance traversed. The present invention represents a different approach wherein the requisite pulses are formed without transmitter. In the means of the invention, there has been connected to the tachometer generator (TG) giving the velocity of the lift, an analog/digital converter (A/D) which delivers to the electronics taking care of floor and location determination, a pulse train (PT) of which the frequency is proportional to the lift's velocity, whereby the total number of pulses per time unit is thus proportional to the distance travelled. In this manner, the pulse transmitter system (PP,PT) can be simply replaced by an IC circuit (A/D).

Abstract: Apparatus for interfacing weighing data with a lift control system that has been carried out with an operator amplifier circuit comprising a speed controller amplifier (NS) of which the plus terminal has been connected to ground and at the minus terminal enter the speed set-point value and the current speed value and further from the minus terminal has been connected to the output of the speed controller amplifier a stabilizing resistor (R1), and a stabilizing capacitor (C1). The apparatus comprises a start switch (K1) which short-circuits the stabilizing resistor (R1) and an auxiliary start switch (K1A) which connects the juncture of the stabilizing resistor (R1) and capacitor (C1) to the terminals of the weighing data resistors (R7) and (R8). The other end of the latter weighing datum resistor (R8) is connected to the output of the speed controller amplifier (NS) and to the other end of the foremost weighing datum resistor (R7) has been connected the external weighing datum.
