Title: Impeller for centrifugal pump handling effluent - has channels through disc and shroud rine to suction side to improve stability
Inventor: HERGT PETER DIPL ING
IPC: F04D29/22
Filed: 1973-11-16
Abstract: The impeller has a disc carrying curved blades with a shroud ring on the outside linking all the blades together. Channels are drilled in the shroud ring and in the disc in each blade space and parallel to the blades allowing partially compressed liquid to flow back to the suction side. In many cases the blades cannot follow the hydrodynamically ideal shape for structural or other reasons and flow through them can become unstable. The leakage channels stabilise the flow sufficiently to counteract any loss of efficiency due to the leakage and further produce an overall gain in efficiency.

Patent DE-2411313-A1 (DE)
Title: Measuring device for roundness of workpiece - caters for a broken surface, and the device is automatically centred
IPC: G01B7/28
Filed: 1974-03-09
Abstract: A limit switch is inserted into the test value amplification channel and disconnects the test feeler output voltage when it exceeds a certain small set value, e.g. 10%, due to the workpiece surface interruption and the electric gauge finger falling into the gap, so that it has no effect on the centring and compensation circuit during the gap crossing. It inserts instead a test signal corresponding to an ideally round workpiece. The test value at the amplifier output is continuously stored in an analogue store, e.g. a capacitor, as such or as its mean value. When the limit switch operates owing to the surface interruption, the store is disconnected from the amplifier, and the last stored instantaneous value is used as a test signal for compensation and centring.
Patent DE-2413790-A1 (DE)
Title: Dishwasher with self-cleaning fine filter - has auxiliary water storage chamber which during emptying draws dirt back through filter
Inventor: HARTL HORST
IPC: A47L15/42
Filed: 1974-03-22
Abstract: The dish washer is provided with a water circulating system emanating from the collecting container and a chamber which is connected into the circulation system and is separate from the wate system is formed in the collecting basin by a lid and a sealingly adjacent vertically aligned partition and at the bottom by a fine filter screen which is mounted at a distance above the base of the collecting basin. When the waste pump is switched on the water in this separate chamber is drawn off through the fine filter against the circulation flow so that the fine filter is automatically cleaned of any dirt and particles. As an extra safety precaution against overheating it is preferable if the inlet to the circulation system is above the level for the fine filter so that the heating element which are located beneath the latter are always in water, at least during rinsing.
