Title: Molten metal sample collector for metallurgical analyses - has evacuated glass probe filled by pressure of metal on collapsible wall
Inventor: KOENIG PAUL DR RER NAT
IPC: G01N1/14
Filed: 1975-07-01
Abstract: The specimen extractor for use with molten metals comprises an evacuated hollow probe of high m.pt. glass. The upper tubular part is about 20mm long and opens into a disc-shaped chamber with convex walls. A tube of 6-8 mm dia. and 30-100 mm long, joins the chamber with the foot of the probe. The slightly pointed tip has a thickened wall to give strength and a bulbous part with a considerably thinner wall. The reinforced tip is forced through the crust of the molten metal. The thin wall collapses under pressure and the internal vacuum and molten metal fills the probe. When cool, the glass can be removed, providing a solid metal disc and rod for use in different analytical apparatus.

Title: Gasifying open storage ponds - using rotating aerators having trailing chains to disturb sediment on bottom
Inventor: POEPEL FRANZ PROF DR ING HABIL
IPC: B01F7/16
Filed: 1976-10-16
Abstract: Gasification of liquids in open storages uses a rotor which is immersed in the liquid. This draws in gas esp. air and water from a depth, mixes the two and then disperses them from the outlet. The rotor rotates about a centrally located mooring pole, being drien by the pumping action of the ejected material. The device is supported on floats held by extending guides. From these are suspended onto the botom of lake, etc. chains, rakes, weights or scrapers. These extend outside the circles or loin created by the rotors rotating around the central axis of the mounting pole. The chains can be garlands forming a loop which drags over the surface. Used for aeration and gassification of open water storages e.g. lakes, ponds, etc. The system described agitates this sludge so that it can be digested by the aerobic processes occurring in the bulk of the liquid.
