Abstract: A speed controllable three phase drive including an asynchronous motor having a slip ring rotor which can be connected to a three phase network and a d.c. motor mechanically coupled to the asynchronous motor with the d.c. motor fed through an uncontrolled rectifier connected to the slip ring of the asynchronous motor has a controlled static converter in series with the uncontrolled rectifier and d.c. motor. In an alternate embodiment the d.c. motor is replaced by a static converter motor fed by a controlled inverter connected to the uncontrolled rectifier. The controlled static converter is coupled to the three phase network to result in a three phase drive with a greater speed range and a lower reactive power requirement as compared to subsynchronous static converter cascades.

Abstract: An elevator system is powered by a multiphased motor to which power is supplied from an inverter, which is powered by a battery. The collector-emitter voltage across the output transistors in the inverter is sensed as the transistors are turned on, and if the voltage does not drop to the saturation voltage within a certain time, the drive to the inverter is discontinued. If at any time while the transistors are in saturation saturation voltage rises, the drive is turned off. To start the drive, the transistors are permitted to turn on for a short interval of time. If, following that interval of time, the saturation voltage is not correct, the drive is turned off. The inverter has separate sections for driving each winding of the motor, and each of these sections has a separate power supply and fault detection circuit, which operates to measure the saturation voltage across the transistor and provide a fault signal which indicates that the drive should be terminated.

Abstract: The invention relates to a telecommunication system in which alternatingly circuit-switeched and packet-switched information is transmitted in time-divided form between transmitter and receiver equipments. A system is described for multiplexing telephony channels with static and dynamic capacity. A static channel occupies a time slot in a fixed frame structure. The dynamic channels utilize idle time slots. A status bit per time slot states whether the time slot is occupied or not. According to the invention, equipment for transmitting circuit-switched information is combined with equipment for transmitting packet-switched information, such that a hybrid system is obtained which, under the control of a status bit, alternatingly transfers information from the respective equipment in response to the polarity of the status bit. A circuit-switching memory (CS) is continuously scanned in a multiplexer (DS1). Data words are stored in the memory, each word corresponding to a time slot, which in turn corresponds to an information channel in a TDM system. A status bit of the mentioned kind is inserted in each data word. For an occupied time slot in the memory CS the word from the memory CS is transmitted to a circuit-switching receiver (CR) via a line (L) and a demultiplexer DS2. For an idle time slot in the memory CS sends the word which is first in the queue in a buffer memory PS included in a packet-switching connection and is transmitted to a packet-switching receiver PR via the line L.

Abstract: The invention relates to a wet-treatment process for purification and heat utilisation of all the flue gases and exhaust gases (off-gases) resulting from the combustion of solid, liquid and gaseous fuels, and is particularly suitable for use in medium-size and small heat plants. The purpose of the invention is to specify an effective and universal process in which the flue gases or exhaust gases are brought into contact, by means of a jet scrubber or jet-driven appliance, with a scrubbing fluid, and which ensures optimal provision of the momentum exchange conditions and of the purification and heat exchange process while minimising the investment and operating cost balance. According to the invention, for this purpose, admixture takes place, either to a circulating scrubbing fluid in the region between liquid pump and jet nozzle of the jet scrubber or appliance, or to a scrubbing fluid generated outside the wet-treatment installation, in the vicinity of a separate discharge line run to the jet nozzle, of a high-temperature gas or gas mixture whose temperature is above the boiling temperature of the scrubbing fluid. The gas or gas mixture is preferably taken from the ambient air, the flue gas stream or the purified exhaust gas stream.
