Abstract: A method and a circuit arrangement are disclosed for transmitting binary signals between peripheral units which are connected to one another via a central bus line system. The signal transmission is to take place without the necessity of including a central processor, which is likewise connected to the central bus system. For this purpose, it is provided that signal transmission requests from the individual peripheral units are transmitted to a memory access device which is also connected to the central bus line system and which, in response to the receipt of such transmission request, de-activates the central processor in respect of the transmission of signals to the central bus line system. The memory access device supplies the peripheral units which are to participate in a signal transmission operation with control signals which transform the latter from a starting state into a transmitting state or into a receiving state and then, in alternation with control signals which serve for the output and receipt of signal groups. Following the transmission of the last signal of the number of signals reported to the memory access device in respect of a signal transmission operation, the memory access device supplies the peripheral units with a reset signal by which the same are returned from their transmitting and receiving states into their starting states.

Abstract: A solar energy collection system, instead of using a closed primary loop in heat exchange relation with a secondary loop passes water to be delivered to the end user through the collector 3 prior to storage in a storage tank 6. The flow rate of water through the collector is varied by means of a pump or valve 4 so as to increase as the power available for collection increases. Furthermore unlike conventional systems where the amount of water in the tank 6 is maintained substantially constant, the level is allowed to vary within wide limits, the tank only being refilled when adequate power is available at the solar collector 3.

Granted: 1988-09-14
Abstract: A power supply is provided for energizing a trip signal generator and for selectively operating a device in response to the detection by the trip signal generator of overcurrent in a alternating current line. The power supply receives input of full-wave rectified current that is directly proportional to the alternating current in the line. A regulator circuit is also provided to power the trip signal generator and other circuitry. When current initially flows in the line the regulator rapidly produces an output voltage approximately equal to the input voltage up to a first voltage level. When the input voltage exceeds that level, the output voltage of the regulator increases at a slower rate than the input voltage to permit regulation of the output voltage. When energized, the output voltage is regulated at a predetermined constant level. The power supply also includes an energy storage circuit for supplying the input voltage to the regulator and to a circuit interrupter when desired. A control portion in conjunction with a switch portion alternately shunts current away from or permits current to flow to the energy storage portion and regulator portion to maintain the voltage across the energy storage portion within a predetermined range. The predetermined voltage range of the energy storage circuit is shifted higher upon receipt of a signal from the trip signal generator to increase the amount of energy stored in the energy storage circuit for interrupting the circuit in the line.

Abstract: A quick-coupling assembly for fluid conduits and of the kind comprising a first sleeve-shaped member, which at one end is provided with a number of resilient tongues provided with at least one projection intended to be locked behind at least one shoulder or the like in a second sleeve-shaped member for being connected to this and a ring being actually displaceable in the second member towards and away from the shoulder and being designed to cooperate with the tongues for compressing these so that they can be moved past the shoulder. The object of the invention is to provide a quick-coupling which despite high pressures (e.g. 350 bar) is easily rotatable so that a pressure hose connected to the coupling really can rotate, which is especially important at many hydraulic arrangement where relative movements occur between different structural parts connected to each other by pressure hoses. This object has been solved by the fact that the shoulder (5) comprises a ring (10) which is rotatably but undisplaceably arranged with respect to the second sleeve-shaped member (4).
