Patent DE-2449597-A1 (DE)
Title: Non wetting fuel can for liquid metal cooled reactor - has fine helically wound wire to prevent hot spots developing
Inventor: VINZ PETER DIPL ING
IPC: G21C3/338
Filed: 1974-10-18
Abstract: A fuel rod with a non-wetting surface, e.g. a nitrided coating for a liq. metal-cooled reactor has a wetting wire (W1-W6) wound helically around it. A stainless steel wire of 0.05-0.5 mm dia. is pref. used, with a spacing between the turns of 1/10 times the wire dia. The wire is pref. wound on under prestress and bonded to the fuel can (2) by diffusion welding or soldering. The rod is esp. for sodium-cooled reactors, in which a non-wetting surface is used on the fuel rod can to prevent delayed boiling of the sodium, leading to explosive evapn. Such a surface is, however, liable to the development of hot-spots, resulting in burn-out of the fuel can. The use of the helical wire prevents this, since an immediate formation of a vapour bubble occurs, to form a meniscus at the vapour-liq. interface. At this interface, thermal stability exists and the incipient bubbles are swept away by the transverse coolant flow, indicated by arrows. The heat transfer is sufficient to prevent a hot spot growing.

Title: Direct drive system for roller shutter - worn gear meshes with motor powered worm
IPC: E06B9/84
Filed: 1974-12-20
Abstract: A spring-loaded locking bolt (4), which can be held in a rest position by a pilot wheel (3) and ball bearing (5), is positioned on the worm gear (2) between hub and teeth (16).

Title: High throughput activated sludge treatment - introducing sewage and recycled sludge through distributors before aerators in recirculated emulsion
Inventor: SCHNITZLER ERWIN DR ING
IPC: C02F3/00
Filed: 1975-05-07
Abstract: In a sewage treatment system including an activated sludge tank and a reclarification tank, the sewage and the recycled sludge are introduced in fine distribution in the aeration zone into the sewage/activated sludge emulsion. The oxygen content in the latter is measured in an outflow to the reclarification basin and the aeration is controlled accordingly. This enables the mixing degree and the equilibrium between growth and flushing away of the microorganisms to be controlled to eliminate excessive sludge production. The better kinematic conditions for the reaction in the first phase results in a better efficiency. The specific throughput of a plant is thereby increased.
