Patent ES-8200806-A1 (ES)
Title: Electrical installation arrangement.
IPC: H04B10/524
Filed: 1980-12-22
Abstract: A remote control circuit for the control of one or more functions of a device, for example a toy or transparency projector, comprises a transmitter for transmitting control signal pulses and a receiver for evaluating the transmitted pulses, the design of the transmitter being such that the number of its components and its consumption of current are minimized. The transmitter accordingly comprises a monostable multivibrator with two complementary transistors. The collector of the first transistor is connected to the base of the second transistor, and the collector of the second transistor is connected to a signal pulse transmitting component, for example an infrared diode, and through a resistance-capacitance coupling to the base of the first transistor. Also connected to the base of the first transistor is a number of components determining different pulse intervals and corresponding in number to the functions to be controlled. The components can be individually switched in by respective switches. The receiver comprises a resistor-capacitor charging-circuit adapted to provide a sawtooth voltage dependent on the pulse intervals and a voltage level detecting stage for detecting different voltage levels and selectively controlling the functions in dependence on detected levels.

Title: Means for transporting/rotating the pot of a smelting furnace
IPC: F27B3/10
Filed: 1981-02-26
Abstract: The present invention relates to means for transporting/rotating the pot of a smelting furnace. The invention is particularly adapted to furnaces having rotating furnace pots and in particular to furnaces with a split furnace body. The pot is locked from rotation simply by letting the furnace pot rest on its foundation during intervals in which the pot is supposed to be at rest. The pot is rotatably arranged with respect to the furnace foundation and the rotation is produced by means of a plurality of transport means. The transport means are preferably evenly arranged around the circumference of the pot. The transport means comprises lifting means which periodically lift the pot partly or completely off its foundation. The lifting means are preferably of a type which provide a lifting force in vertical direction, either by means of a hydraulic medium or compressed air. The lifting means may for example be formed by one or more flexible hoses which communicates with a pressure producing source. According to the present invention the resistance of rotation imposed by the charge material may provide rotation of the pot, said resistance being exploited to transfer rotation from the upper section to the lower section of the pot.
