Title: Digital/analog converter
Inventor: GULCZYNSKI ZDZISLAW
IPC: H03M1/00
Filed: 1986-03-03
Abstract: The invention relates to a digital/analog converter (DAW) for converting an input code into the corresponding output voltage. The field of use is in digital systems where fast, highly accurate and high-resolution conversion is required. The DAW developed in accordance with the invention essentially consists of counters and an integrator. If ROMs are allocated to the counters, digital error correction can be achieved. The most significant and least significant data bits of the input code are loaded into the down counters, in each case Z2 and Z1, which are then enabled. At the same time, the respective switches S2 and S1 are closed and switch S is opened; the output voltage of the amplifier now rises linearly. If one of the counters reaches zero, the respective switch is opened; the loading current of the capacitor C is reduced. If the last switch is opened, the current is equal to zero. The output voltage is then stored, free of transient voltage peaks (glitches) and is present at the output which is already of low impedance. <IMAGE>

Patent DE-3717482-A1 (DE)
Title: Method and circuit arrangement for driving a GTO thyristor
Inventor: SCHINDLER ANDREAS DR
IPC: H03K17/082
Filed: 1987-05-23
Abstract: Power-electronic circuits with GTO thyristors (V1) need for their operation limiting networks which delay the current rise in the thyristor on turn-on and the voltage rise across the thyristor on turn-off. A reactor (LE) delaying the current rise must be demagnetised during the off-state of the GTO thyristor (V1) before the next turning-on. A capacitor (CA) delaying the voltage rise must be discharged during the conduction phase following the off state before the turning-on. This results in a minimum turn-on time (tEmin) and a minimum turn-off time (tAmin) as off times for the GTO thyristor. To derive the interlocking conditions for the change of the switching state of the GTO thyristor (V1), the determining parameters, i.e. the voltage (UCA) across the capacitor (CA) and the current (ILE) through the reactor (LE) are measured directly or determined or regenerated from proportional variables and compared with predetermined limit values based on the GTO thyristor type used. As a result, the interlocking functions are independent of the dimensioning of the limiting network. Furthermore, the off times produced dynamically vary with the loading of the GTO thyristor (V1), i.e. at lower switching currents, higher switching frequencies are possible. <IMAGE>

Patent DE-3738783-A1 (DE)
IPC: A23F5/20
Filed: 1987-11-14
Abstract: Known processes for decaffeinating green coffee using water-containing liquid carbon dioxide operate above the critical pressure of the carbon dioxide. This is considered necessary, as it is feared that aroma components would be coextracted at lower pressures. In contrast, the object of the invention is to provide a more economical decaffeination process without adversely affecting the aroma of the green coffee. This object is achieved by a process for green coffee decaffeination in which the green coffee is adjusted to an increased water content and then selectively extracted with water-containing liquid carbon dioxide at below the critical pressure of the carbon dioxide. This can be carried out particularly economically; surprisingly no aroma loss at all takes place by coextraction of constituents.
