Patent NL-7602420-A (NL)
Title: Fluid divider for surface distribution and collection - esp. etching fluid, maintaining constantly fresh supply without any problems
IPC: C23F1/08
Filed: 1976-03-08
Abstract: A device has a detail with a number of fluid source channels for delivering the fluid to the working surface. The source channels are spaced some distance from each other, so as to distributed the fluid uniformly over the surface positioned some distance from the channels. The details with the fluid source channels also has a number of drainage openings spaced uniformly apart so as to collect and evacuate the fluid delivered by the source channels. A supporting arrangement such as a plate appropriately relatively to the detail with the fluid source channels, so that the object to be etched can be inserted between them and supported hydrostatically. This guarantees a high class accurately etched product by uniformly distributed and constantly refreshed fluid. There are no difficulties as with immersion baths and no possibilities of damage to the protective layers.

Title: Ultrasonic flowmeter measuring via V=shaped section of pipeline - has electronic circuits detecting differences in pulse transmission time or phase between sinusoidal signals
IPC: G01F1/66
Filed: 1983-11-18
Abstract: A horizontal input tube (1) is connected via a V-shaped section of pipe to the horizontal output tube (2). At the junction of the V is a piezo-electric ultrasonic transmitter (5), and there are two receivers (6,7) at the points of the V.

Title: Method and device for the removal of nitrogen and sulphur oxides from flue gases.
IPC: B01D53/60
Filed: 1992-02-04
Abstract: The invention provides a method and device for the removal of nitrogen and/or sulphur oxides from flue gases by causing these gases to rise through a column packed with inert material, while a saturated solution of ozone in water flows downwards via the column, with the quantity of ozone added per unit of time being set at a value such that the molar ratio of ozone to nitrogen and/or sulphur oxides is less than 1:1 and that the ozone solution added is free of alkaline substances. The molar ratio of ozone to nitrogen and/or sulphur oxides is preferably less than 0.5:1. The purified flue gases can be passed through an activated charcoal filter prior to the discharge thereof. The water coming out at the bottom of the column, with oxides dissolved therein, can be fed in again at the top of the column after saturation with ozone, until an acid of industrial quality is obtained.
