Patent DE-2346801-A1 (DE)
Title: Washing machine ion exchanger - with valves to regulate water-softening time during wash and rinse cycles
IPC: D06F39/00
Filed: 1973-09-18
Abstract: In a laundry washing machine, where softened water is required for the pre-wash cycle, the ion exchanger, which is charged with iodine-free regeneration salt, delivers the water for this phase. Thereafter the ion exchanger is disconnected by valves to allow unsoftened water to bypass it for the main wash and rinse cycles, the washing machine being only partially emptied after the pre-wash to ensure that some softened lye remains. This allows the ion exchanger its required 40 mins. to prepare the next charge of softened water, and be ready for the next load, even though the rinsing cycle lasts only about 20 mins.

Title: Sewage water purification system using activated sludge - surface ventilators assist two-directional flow in closed circuit trenches
Inventor: BOTT RUDOLF DIPL-ING
IPC: C02F3/16
Filed: 1973-10-24
Abstract: A sewage water purification system using an activated sludge process in which the water circulates round a closed circuit of trenches, and in which oxygen is introduced into the water by means of a surface ventilator rotating on a vertical shaft, has a vertical partitioning wall dividing the trench into two sections in which the flow is in opposite directions; extending beneath the axis of the surface ventilator from the trench bottom to a zone immediately below the vanes; and running below the water level to the limit of the circle in which water is ejected. At the perimeter of the ventilator vanes, the distance between the top edge of the partition and the water level, is one to two times that of the immersion depth of the ventilator vanes and in the zone in which the water is scattered it corresponds approx. to the observed depth to which the water mixed with air bubbles sinks below the surface. A normal large installation using 110 surface ventilators divided into five reversing systems consumed annually 250 mill. kWh. Employing the arrangement described here only four systems are necessary with an annual saving of about 60 mill kWh.

Title: Rotor blades centroid position correction - by adhering to predetermined weight of rotor blades
Inventor: KUNSTWADL ERNST
IPC: G01M1/32
Filed: 1973-12-19

Title: Doppler pulsed radar device - has compensator for doppler shift of echoes from fixed targets due to antenna movement
Inventor: WIEDEMANN KURT DR ING
IPC: G01S13/524
Filed: 1974-04-19
Abstract: The compensation is realised by variation of the heterodyne frequency in the radar reception channel by an auxiliary frequency generated in an auxiliary oscillator. The centre frequency fm of the auxiliary oscillator is, when antenna speed is zero, fm = kfp, where K is an integer greater than 0, and fp is the radar pulse frequency. When the antenna movement generates a Dopple shift fD of the radar transmission frequency, the auxiliary oscillator frequency is change by a value proportional to the Doppler shift, so that echo signals from fixed targets are still suppressed.
