Abstract: An elevator safety circuit has a series chain of contacts connected between at least one safety relay and an electric power supply and a monitoring device monitoring the voltage and current in the series chain. A signal from the safety relay is transmitted to an elevator control. The voltage across the safety relay is tapped and transmitted to a network connected to a voltage converter of the power supply. If all the contacts of the series chain are closed, the voltage across the safety relay is held constant. Regulation of the voltage across the safety relay makes the safety circuit, with respect to voltage drop, independent of the length of the cabling connecting the contacts.

Abstract: A method of and an apparatus for configuring elevator controls permit external signal emitters and signal receivers to be connected to freely selectable connection points of an input/output module. For each of the occupied connection points on the input/output module at least one programmable connection configuration module can be assigned which delivers to the control processor via a bus system the requisite information concerning the type and function of the signal emitter or signal receiver connected to the corresponding connection point.

Abstract: An elevator user creates on a user terminal an individual user program, that is adapted to his needs, for operating the elevator. The user terminal can include a keypad for selecting commands and entering values, and a screen for displaying the command sequence. Depending upon authorization, the user can access the entire command set or only certain commands. The user program is transmitted to a terminal of an elevator control by wireless communication and proceeds to a program control which adds to the user program data required for execution and stores it in a memory. A task manager of the control program initiates the execution of the user program by an interpreter that interprets the program step by step. In the case of elevator-specific instructions such as, for example, travel commands or door opening commands, the interpreter calls up an interface that initiates the further execution by an elevator control.

Abstract: A definite switching-off of drive equipment for elevators is accomplished with a control at an input side external of a frequency changer power unit that ascertains the presence or the absence of monitoring signals which are derived from the mains voltage at the input of the frequency changer power unit. Upon ascertaining the presence of one or more such signals when the drive is at standstill, the input side control interrupts the energy flow to the frequency changer power unit by generating a switching-off signal to a switching device to disconnect the mains voltage.

Abstract: A vehicle of a transportation system is moved by a drive supplied with electrical energy from an energy store. For the purpose of loading the energy store at a stop, a supply unit is provided, by which energy from a stationary energy supply, for example the public power supply or a solar generator, is transferred wirelessly to the energy store. A modulator raises the frequency of the energy to a higher level. The energy is transferred from the primary winding of a coupling transformer across an air gap to a secondary winding. The primary winding is stationary and the secondary winding is located on the vehicle. The energy, whose frequency is set at a high level to improve the energy density, is delivered to a demodulator on the vehicle side which, under the control of a controller, converts the energy into a form suitable for charging the energy store.

Abstract: A multi-segment display for the representation of alphanumeric characters, formed by uniting several character-display elements having multiple segments. The united display segment elements have common vertical segments. Greater freedom for representing the characters while requiring the smallest possible number of segments is obtained by such a construction. In addition, gaps between character representation can be minimized or eliminated, allowing characters to be represented in a centered arrangement with a regular spacing.

Abstract: In equipment for powder-coating, workpieces such as escalator steps are subjected to a current treatment in an anodizing unit. A conveying means advancing carriers for the workpieces is lowered over a tank so that the workpieces in transit are immersed in and continue transit within a bath and after a specific dwell time are lifted back out of the bath at the end of the tank. Arranged in the tank region is a current feed, such as a bus bar, which extends parallel to the travel path of the conveying means. Each carrier is provided with a current take-off which connects the carrier with the current feed. The current connection is produced on lowering the carrier into the bath and interrupted on raising the carrier from the bath.

Abstract: A transport system with several autonomous vehicles includes a terminal for a user to input his travel destination. The boarding location and the allocated vehicle are selected for serving the travel request and this information is communicated to the user as an allocated symbol on a display of the terminal. The user can then go to the indicated boarding location. As vehicles arrive at the boarding location, each is indicated on another display by a flashing symbol associated with that vehicle. Thus, the user knows to board only when the flashing symbol corresponds to his allocated symbol.
