Title: Falling film distillation of fatty acids - with bypass recycling of vapour to give increased output
Inventor: STAGE HERMANN DIPL-CHEM DR
IPC: B01D1/06
Filed: 1973-10-20
Abstract: A falling film evaporator, esp. for fatty acids distillation plants, has a vapour line, which constitutes a return from a point below the tickler surfaces to a point above them, thus enabling part of the vapour to ascend without acting as a brake to the downward flow of the films. The sump pref. has a discharge line leading from it to the next distillation stage, without any forced recirculation of the liquid in the sump. Since the vapour no longer applies a limiting effect, by its upward retarding action, to the downward flow and the evaporation rate, the performance of the plant can be considerably increased.

Title: Transmission of digital signals over analogue lines - by simplified converter to high frequency carrier offering low attenuation
Inventor: POSPISCHIL REGINHARD DR ING
IPC: H04L27/02
Filed: 1975-06-13
Abstract: Transmission of pseudo-ternary coded digital signals over one or more of a number of symmetrical pairs or coaxial lines forming a cable intended for speech and carrier frequencies in which the transmission range of the carrier signals overlaps the basic band for the digital signals, in which at the transmitting end the digital signals are converted to a frequency band higher than that of the analogue signals by mixing with a clock signals of a rate half that of the signals to be converted with pulses shifted by a half bit period of the signal to be converted. From the resulting pseudocoded signal at higher rate the part lying above the clock frequency with the highest energy is filtered out and transmitted together with the carrier frequency signals through one or more lines of the cable. The transmitted signal is regenerated at regular intervals along the transmission path by derivation of a full pseudo-ternary signal from the transmitted signal, after which the part of the regenerated signal in the relevant frequency range with the highest energy is again filtered out and transmitted further; at the receiving end the original is recovered by conversion of the receive signal using a carrier with an appropriate frequency.
