Liquefaction of methane-rich gases e.g. natural gas, refinery gas, ethylene plant gas, where required in small amounts for transport or storage. The process and plant are simple and economic where liquid nitrogen is available at low cost, and quantities do not justify a large liquefaction plant.
Patent DE-2363936-A1 (DE)
Title: Washing(-up) machine with two magnetic valves for detergents - simultaneous operation of which cause pressure to operate pump for softener
Inventor: GRUNWALD RUDOLF DIPL ING
IPC: D06F39/02
Filed: 1973-12-20
Abstract: Operation of either of the magnetic valves of the washing machine causes a control piston to slide against the opposition of springs and allow water to flow into the detergent chamber on the side at which pressure is applied. When both magnetic valves operate, pressure is applied to both sides of the piston which consequently does not slide, but causes a pressure build-up in the common piping which leads to operation of the pump, which performs one stroke and delivers a measured quantity of liq.

Title: Timed initiation of data transmission - at least two data subscribers are connected to digital switching network
Inventor: FIEDLER HELMUT DIPL ING
IPC: H04L12/00
Filed: 1974-06-05
Abstract: After the usual connection build-up a pulse is generated in a data transmission unit of the calling subscriber. It is transmitted through the switching network to the called subscriber. It is transmitted through the switching network to the called subscriber data transmission unit. End of this pulse is evaluated in both data transmission units as the criterion for starting a preparation interval for readiness to transmit and receive respectively. The pulse is transmitted after recognition of the data receiving line polarity reversal, and after an interval fixed for recognition of an engaged signal transmitted by the exchange; or the pulse is transmitted immediately after polarity reversal in the data receiving line of the calling subscriber data transmission unit.
