Patent DE-4123912-A1 (DE)
Title: Oil and water sepn. assembly - moves condensation from thermal reactor without eddies into a collection vessel for any remaining oil to be skimmed from the surface
Inventor: OESTERLE KLAUS
IPC: C02F1/04
Filed: 1991-07-18
Abstract: The assembly to separate water and oil, in water which contains tensides and salts, has a thermal reactor under underpressure to evaporate the water content of the water/oil mixt. The steam is condensed by a cooler or condenser, under underpressure, followed by a collection vessel, also under underpressure, for the condensed water to flow in smoothly and without eddying. Any oil carried through with the evaporated water is sepd. from the surface of the condensed water in the collection vessel. The cooler and condenser operates on a counter-flow principle, or as a falling flow unit. The coldest zone in the cooler and condenser is near the surface of the collected condensation, where the condensation passes through a falling pipe, under underpressure and with a cross section only partially filled with the condensation, for the water to flow to the collection vessel. The outlet pipe has a sufficiently long length for any steam above the water level in the pipe to condense during the flow time. ADVANTAGE - The operation ensures that any oil carried through by the steam is effectively removed.
Patent DE-4125360-A1 (DE)
Title: Flat convex lens prodn., for e.g. laser diode-to-optical fibre coupler - making several lenses with rectangular cross=section from silicon@ wafer and with flat plane parallel or inclined to orthogonal plane
Inventor: HALTENORTH HELMUT DIPL ING DR
IPC: B24B19/22
Filed: 1991-07-31
Abstract: The method involves polishing and roughening silicon wafer on one flat surface and forming group of parallel line-shaped deepened formations in the other flat surface. At right-angles to the first group, a second group of parallel line-shaped deepened formations are made, whereby a number of stamps with the required rectangular lens cross-section remain. On the surface of a stamp, a rotary tool rotating around an axis aligned to the stamp central axis grinds and polishes a spherical surface, which forms the convex lens surface. The lens surface is then demirrored and the deepened formations are sawn over the total wafer thickness, so that the individual convex lenses are available. USE/ADVANTAGE - For use in fibre-optic communications. To produce flat convex lenses from silicon wafer.

Title: Apparatus for lifting plants by the individual root balls
Inventor: HEITZLER KARL
IPC: A01G23/04
Filed: 1993-01-21
Abstract: The invention relates to an apparatus for separating and detaching root balls of plants, in particular in nurseries. The apparatus is designed as an excavator-loader. Arranged on the extension arm of the excavator-loader is a bow-shaped undercutting and lifting cutter which can pivot through the soil around the root ball. The cutter is fitted on the double-hinged connection. The lifting cutter can be set in various positions by means of the pivoting part. The rotating part makes it possible to lift at least two or even more rows of plants from one location. The lifting cutter can be set in various angles of inclination by means of the pivoting part, this being highly advantageous when lifting the plant. The apparatus can likewise carry out work on two sides by means of the centrally mounted rotatable and pivotable cutter-bow retaining means. Since the excavator-loader is also fitted on narrow-track tractors, it is advantageous to arrange two supporting wheels which can be adjusted in width. The apparatus may also be designed as a trailer with adjustable wheels and adjustable supporting means. The apparatus, as trailer, is connected to the tractor by means of various elements.

Patent DE-4312804-A1 (DE)
Title: Trunk piston for internal combustion engines
Inventor: SCHNEIDER PETER
IPC: F02F3/10
Filed: 1993-04-20
Abstract: In a reciprocating piston, especially one of metal, for internal combustion engines, it is proposed to improve the exhaust emission performance by means of a tighter radial clearance between the piston top land and the cylinder wall guiding the piston. The intention is that, despite a low top land clearance, there should be no risk of friction on the piston or the cylinder wall due to too tight a clearance. To this end the piston top land is coated with a layer which has a lower abrasion resistance than the top land base material, the diameter of the coated top land being designed for a clearance in relation to the cylinder guiding the piston, which is less than the minimum which would be admissible for a serviceable piston in engine operation in the absence of a coating.

Title: Automatic filling and refilling unit for existing or new heating installations with warning device for heating water and domestic hot water
Inventor: DUMMANN KLAUS
IPC: F24D3/10
Filed: 1993-07-30
Abstract: Functioning of the automatic filling/refilling:   Constant water level in the heating installation, thus no gurgling or lukewarm radiators. No monitoring during or at the start of the heating period. Subsequent bleeding of radiators is no longer necessry, since water loss in the installation, caused by decomposition, is compensated for. In new installations, filling without monitoring of the water pressure. Old installations are monitored for defects (pipe fracture, rusting through). In the case of a defect of the heating installation, light or sound is used to draw attention to the fact that the filling operation is being stopped.   Functioning of the domestic hot water filter monitoring: if the filter is clogged, flashlight or sound is used to indicate in good time that the filter must be replaced.
