Filed: 1984-11-19
Abstract: Die Erfindung dient der Bereitstellung eines Sensors fuer die Volumenstrommessung, der bevorzugt zur Ueberwachung einer automatischen und kontrollierten Beatmung eingesetzt werden kann, der sich aber auch fuer die Erfassung anderer schwacher Volumenstroeme gasfoermiger Medien eignet. Die bekannten, nach dem Prinzip der Karmanschen-Wirbelstrasse arbeitenden Sensoren sind bei kleinen Stroemungsgeschwindigkeiten gekennzeichnet durch periodische Schwankungen, einen unzureichenden Signal-Rausch-Abstand und einen ebenso unbefriedigenden linearen Zusammenhang zwischen Wirbelfrequenz und Volumenstrom. Ziel und Aufgabe der Erfindung ist es, diese negativen Eigenschaften unwirksam zu machen, so dass fuer einen weiten Bereich von Stroemungsgeschwindigkeiten, einschliesslich der schwacher Gasbewegungen, ein Sensor mit hoher Messgenauigkeit entsteht. Das wird geloest mit einem Sensor, dessen Messstrecke einlassseitig mit einer parabel- oder hyperbelfoermig gestalteten Verengung Versehen ist, die eine bessere Wirbelbildung eines ihr nachgeordneten Stroemungskoerpers mit prismatischem Querschnitt bewirkt.

Title: Static microirrigator with uniform diffusion and wide radius with triple range
Inventor: PASQUALE TRAVAGLINI
IPC: A01G/
Filed: 1989-03-31
Granted: 1993-09-03
Abstract: The invention is concerned with a static microirrigator for use in fixed irrigation equipment for orchards, parks, gardens etc., which can be manufactured in two different forms for different uses and which we shall call A and B. It is able to produce a very wide and wet surface (more than 10 metres for type A and 14 metres for type B) without the use of sophisticated mechanisms with rotating parts and micropores, which can also easily become clogged but by adopting a simple system, which is functional and does not become clogged. This system comprises an assembly of microchannels, which are open to the air and small teeth appropriately obtained on the surface of an anvil on which a supply jet is inserted. Both the small channels and small teeth function as nozzles and as such dispose of the water from the jet diffusing it in a circle in the form of small squirts (one for each small channel and one for each small tooth). The kinetic energy of the squirts obtained with this system, with all conditions being equal, is greater because the channels and small teeth, being open, oppose less passive resistance in relation to the nozzles while conserving their same pressure. The system is self-cleaning because diffusion takes place in the open air and on continuous surfaces in a radial direction. Therefore impurities are not trapped but propelled by the water, slide away along the channels and on the surface of the small teeth. The microirrigators on sale today, which are rotary and static, present all, more or less, of the drawbacks which do not allow them to fully satisfy the needs of microirrigation: a) the static sprinkler-type provide too short a range, even with considerable deliveries, with a concentration of nearly all the water in the space under the sprinkler, leaving large surrounding spaces dry; b) microjets which squirt only wet the external crown where the squirts fall, leaving the internal area dry; what is more they have the drawback of becoming easily clogged since they trap the impurities present in the water inside the diffusion cap; c) rotary microirrigators, while creating a sufficient wet radius and sufficiently uniform diffusion have the disadvantage of becoming easily clogged, due to both impurities and limescale present in the water which collect on the rotor as well as insufficient pressure. The irrigator as of the invention, avoids all the disadvantages described above and fully satisfies the requirements of microirrigation, both because it avoids any possibilities of clogging and because it produces a very wide uniform wet area, even for small delivery and low pressure, as is better expressed in the technical description of the invention.
