Abstract: A computer (20) implemented control system which includes interface circuitry (21) by which signal intelligence is taken in to the computer from external devices such as sensors (70, 80b) and is fed out from the computer to external devices (61, 65) such as actuators which correctively adjust controlled parameters. An interface circuit (21) for each of the several external devices is made "universal" in that either an analog input (70), bistate input (80b), analog output (61), or bistate output (65) device may be connected to any given one of the terminal points (TP0-TP15). A voltage follower amplifier (50) sends the intelligence signal to an output device (61, 65) through a low-cost diode (51), with negative feedback taken from the downstream side of the diode (51). When an input device (70, 80b) is elected for a given terminal point, simple program editing assures that the diode (51) will be reverse biased to isolate the amplifier (50) from the input signal path. In addition, inaccuracies in the analog output voltage fed to an output device (61, 65) --arising from contact resistances in a separable   connector (90) --are drastically reduced by a dual-path separable connector (90) arrangement which provides two independent circuit connections (100, 101) for the output voltage and for negative feedback.

Abstract: In an adaptive method and apparatus for detecting the formation of frost in a heat pump, the compressor cycle is interrupted and a defrosting operation is begun if the difference between the exterior ambient temperature and exterior heat exchanger temperature exceeds a difference function of the exterior ambient temperature. The length of this defrosting cycle is measured and the difference function is altered if the measured length deviates from a predetermined length of time. The frost formation difference function is initially set as a linear approximation Thereafter the difference function value at the particular exterior ambient temperature is increased if the length of the defrosting is greater than an upper limit value of six minutes and decreased if the length the defrosting is less than a lower limit value of four minutes.

Abstract: In a memory constructed in coordinate form, the memory elements can be activated by halves of an address, to be transferred to the said memory in two successive time slots. The internal memory control receives and stores the first half. On receiving the second half, activation of the respective memory element takes place. If an additional information signal is emitted to it, the memory will also store the first half over a number of activating operations. There is an address generator, which emits this additional information and emits successive addresses one after the other, of which in each case the first half changes from address to address, whereas the second half may remain the same over a number of activating operations (series activation). A multiplexer interchanges the two halves and passes on the second half in the first time slot and the first half in the second time slot. In the case of successively following addresses with a constant second half (series activation), the address generator emits both halves only in the case of the first address and from then on the additional information and, as from the second address, only ever the first half of each of the addresses. <IMAGE>

Abstract: In the valve casing (12) an actuator (50) is arranged, which can be moved from a rest position into a stop position as a function of a pressure differential between the inlet (14) and outlet (16) of the valve (10), in which latter position the actuator (50) prevents complete opening of the valve. This ensures that if the valve (10) opens during a period in which a pressure differential still exists between inlet (14) and outlet (16), any throttling arbitrarily predeterminable in relation to the completely opened state occurs.
