Title: Contactless, capacitive rotary motion detector - has metal or metallised body on impeller axis for compensation of axial play between two stationary, AC fed plates
Inventor: MEHL WILHELM ING
IPC: G01P5/07
Filed: 1980-06-06
Abstract: The detector is primarily intended for use in water meters in conjunction with their bladed rotors. In order to compensate the axial free play of the arrangement, a metal, or metallised disc (1) is mounted between two stationary plates fed with A1 voltage. The body surfaces are electrically interconnected. Preferably the metal disc is mounted in the head of the water meter. Alternately, the disc may form the bladed rotor (7) itself and may have metallised surface coatings in the form of concentive sectors, connecting consecutive archer and forming a replica of sectors on one stationary plate, supplied with a phase of the AC voltage. In any case the metal, or metalised disc is mounted on the rotor axis. Thus the capacitive scanning, responsive to approach of the relevant rotor section, is safeguarded with minimum of free play.

Title: Recovery of clean water and solids from aq. solids - by mixing with fluidising oil and subsequently dehydrating and sepg. mixt.
Inventor: GREENFIELD CHARLES
IPC: C02F11/00
Filed: 1980-08-09
Abstract: Clean water and dry, fluidising oil-free solids are obtd. from aq. solids dehydrated in a light fluidising oil medium. Aq. solids are first mixed with a low viscosity, relatively volatile, water-immiscible light fluidising oil with a boiling point of 150-550 deg.F. The mixt. will remain fluid and pumpable after the removal of the water. The resultant mixt. is dehydrated by heat evapn. to yield a mixed light oil and water vapour and anhydrous solids in oil slurry. The vapours are condensed and sepd. At least some of the fluidising oil is sepd. from the slurry. The resultant solids and oil are contacted with blowing steam to remove the light oil. The sepd. light oils are mixed together and recycled as fluidising oils. The process may be used to dehydrate and de-oil aq. wastes which have an intrinsic value. Examples include sewage sludge, slaughter house effluent, inorganic salts, pharmaceutical prods., tree bark, organic streams from garbage disposal plants, and various aq. chemicals, animal feeds and food prods.

Patent DE-3033290-A1 (DE)
Inventor: MANDRIN CHARLES DIPL ING DR
IPC: C01B5/02
Filed: 1980-09-04
Abstract: The synthesis-gas plant is operated in a number of successive operating periods such that during the first operating period an excess of fresh water is supplied to the synthesis gas plant and the waste water from the resulting mixture is separated in a condenser and supplied to a storage container. During the subsequent operating periods, the waste water stored in the container is used as the feed water for the synthesis gas plant and the waste water obtained on each occasion is stored in the container with increasing deuterium concentration. The waste water obtained during the last operating period and having the highest deuterium concentration is used to feed a plant for producing heavy water. This process, when used in a synthesis gas plant for producing hydrogen, can be used to obtain deuterium-enriched water as a feedstock for a heavy-water plant without expensive additional energy-consuming devices.
