Title: Telephone system target dialling circuit - has store for dialling numbers whose working frequency can be increased
Inventor: ESSER WILHELM
IPC: H04M3/44
Filed: 1976-04-27
Abstract: The circuit consists of an integrated, clock pulse controlled pulse generator with intermediate store for a target dialling number. An integrated clock pulse controlled store is for target dialling numbers. The store is connected to the pulse generator through a common line system for feeding-in series and transfer of digits of a number. Instants of pulse generation by the pulse generator are derived from the working cycle of the units. In order to use the target dialling device as a subscriber number dialling device, the frequency of the working cycle for the store (SP1-SPn) is increased w.r.t. that of the pulse generator (JG), so that transfer of a selected target dialling number digit from the store to the pulse generator is completed with certainty when the first post-selection digit arrives, so that it can be correctly applied to the pulse generator (JG) directly.
Patent DE-2621694-A1 (DE)
Title: DC voltage doubling circuit - uses series capacitors network with first capacitor alternately connected to DC voltage input and to second capacitor
Inventor: ESCHKE BERND ING GRAD
IPC: H02M3/07
Filed: 1976-05-15
Abstract: Voltage doubling circuit comprises a series network of two capacitors from which a voltage having twice the amplitude of the input voltage is taken off. Using the so-called Delon circuit or half-wave voltage doubler requires an a. c. voltage input to derive a d. c. voltage output of twice the amplitude, and use of an inverter in conjunction with the half-wave voltage doubler for d. c. voltage input and d. c. voltage output is expensive and shows poor operational efficiency. The amplitude of a d. c. voltage input may be doubled directly without the use of an inverter to get a d. C. output voltage, and to this end the first capacitor in the series network is alternately connected to the d. C. voltage input, for charging up, and to the second capacitor for discharging, in such a way that the charging voltages of the series connected capacitors are added together.
