Date Mar. 24, 1988.Method for cleansing gas from solid, liquid and/or gaseous contaminants, by bubbling the gas through a liquid bath (32), and by introducing the incoming gas into a distribution means (14) and causing the gas to pass in part-streams through a multiple of inlet orifices (64) located at progressively increasing depths beneath the surface (34) of the liquid (32). With increasing inlet pressure an increasing number of inlet orifices (64) are utilized for an increasing number of part-streams. The gas flow is passed from respective inlet orifices (64) through connecting means (24, 26, 28) to outlet orifices (31) located at a considerably higher height level (h) than corresponding inlet orifices (64). The gas flow is caused to flow out through venturi nozzles (28) and/or to strike against impinger or striking surfaces (39) with a minimum pressure drop corresponding to said height differential (h). In this way full operational pressure is immediately achieved, as soon as gas is passed out through any of the inlet orifices (64), and an intense mixing of gas and liquid as well as a high cleansing efficiency are guaranteed.

Abstract: In a method and a device for coding binary matrices, in particular sparse binary matrices, a matrix is gradually partitioned into sub-matrices During the gradual partitioning the number of binary ones are counted for each resulting sub-matrix. If a resulting sub-matrix does not consist of mixed symbols no further partitioning of that sub-matrix is required. The counted number of binary ones for each sub-matrix is then coded and transmitted. The method provides an efficient coding particularly for sparse binary matrices such as bi-level images or bit maps.

Title: Electrolytically etching patterns with very small dimensions without preliminary masking
Inventor: HEIDARI BABAK
IPC: C25F3/14
Filed: 1998-03-05
Abstract: A film of an etchant-resistant material which is soluble when exposed to electromagnetic radiation is formed on a substrate. A voltage is then applied to an electrode in proximity to the surface, the electrode having conductive regions conforming to the required pattern while the substrate is exposed to perpendicular electromagnetic radiation to remove the passivating layer from the desired areas. An Independent claim is also included for an etching tank comprising a vessel of etching fluid having a voltage source and containing an electrode as above. Preferred Features: The conductive regions of the electrode surface are also transparent to electromagnetic radiation, and are separated by nonconductive and non-transparent regions. The passivating film may be generated by a component of the etchant. The latter may contain a reagent that in concentrated solution is capable of etching isotropically in the absence of an electric field, but is used in low concentration with such a field whereby anisotropic etching occurs.

Abstract: Die vorliegende Erfindung macht sich die Eigenschaft zu Nutze, dass insbesondere in Parkhäusern sogenannte Vorzugsrichtungen bestehen. Diese Vorzugsrichtungen sind nicht auf eine Ebene oder eine Ausrichtung beschränkt. Vorzugsrichtungen sind insbesondere längere Ein- und Ausfahrtstrecken. Das erfindungsgemäße Verfahren erkennt ein Verlassen des digitalisierten Gebiets und bestimmt daraufhin eine derartige Vorzugsrichtung, welche als Hauptachse oder Hauptachsenrichtung definiert wird. Bei Fahrt innerhalb des nicht digitalisierten Gebiets, z. B. eines Parkhauses, wird nun beobachtet, ob das Fahrzeug sich innerhalb einer vorbestimmten Grenze der zuvor definierten Hauptachsenrichtung bewegt. Ist dies der Fall, so wird bestimmt, ob eine Abweichung vorliegt und ggf. diese Abweichung auf die Hauptachsenrichtung korrigiert. Dadurch werden Fehler, die insbesondere von der Richtungserkennung verursacht werden, kompensiert.
