Title: Converter circuit arrangement for pulsed systems
Inventor: HERZL PETER J
IPC: G11C27/02
Filed: 1981-11-05
Abstract: A converter circuit arrangement (10) for pulsed systems serves during a repetition interval for the conversion of an analog voltage to an output current of an intensity related to the voltage as well as for holding the current over the repetition interval. The converter circuit arrangement (10) includes an operational transconductance amplifier (16) having an inverting input (-) and a non-inverting input (+) and a bias terminal (5), the amplifier (16) being activated for the repetition interval by a positive voltage fed into the bias terminal (5). The analog voltage is fed into one of the inputs (+), in order to generate a voltage at the amplifier output (6), which drives a transistor (18) arranged in series with a resistor (21) in a current-generating network (18, 19, 20, 21). As a result, a current flow is induced in the resistor (21), in order to generate a feedback voltage, which is fed into the other input (-) of the amplifier (16). The current in this case assumes an intensity related to the analog voltage. An RC holding network (23, 24) coupled to the amplifier output (6) maintains the driving voltage generated during the repetition interval over this interval, whereby the resulting output current is held. <IMAGE>

Filed: 1981-11-07
Abstract: Root crop cooker, in particular for cooking beetroots, with a cooking chamber (11) which has at the bottom a water bath (19) with heating means for steam production. Two circumferential support belts (14, 16), one (14) above the other (16), are arranged in the cooking chamber (11) and movable independently of one another. On the upper support belt (14), root crops to be cooked are arranged in a layer (29), through which steam is pressed. A part of this steam condenses on the root crops which are thus heated to a given temperature. After a given time, the root crops are transferred over onto the second support belt (16), on which they are arranged in a considerably thicker layer (30) than on the first support belt. The root crops on the second support belt (16) are finish-cooked without steam being supplied and moreover, as a result of their position under the first support belt (14), serve as a filter layer which collects impurities in the condensate which drips down from the first layer (29). The cooker consumes a very small quantity of water and furthermore requires extremely little energy. The cooked root crops also have considerably better quality. <IMAGE>
