Patent IT-MI911159-A1 (IT)
Title: Riscaldatore catalitico senza fiamma a tiraggio naturale
Inventor: BROWNE PAUL A
IPC: F23C13/00
Filed: 1991-04-29
Abstract: Un riscaldatore catalitico a tiraggio naturale comprendente un corpo tubolare che definisce un passaggio allungato per il flusso di fluido avente un ingresso per la miscela aria/combustibile ad una estremità e un'uscita del prodotto di combustione alla sua altra estremità. All'interno del passaggio a valle del bruciatore catalitico primario è disposto un bruciatore catalitico secondario per il completamento della combustione di eventuale combustibile non ossidato contenuto nello scarico proveniente dal bruciatore catalitico primario. Una bassa caduta di pressione attraverso il bruciatore primario viene realizzata mediante una costruzione tubolare del bruciatore tenuta contro la parete di passaggio, mentre la combustione della maggior parte dei reagenti viene realizzata prevedendo un'area appropriata di superficie del catalizzatore. All'interno del bruciatore può essere disposto un elemento di agitazione per spingere in modo delicato i reagenti all'infuori verso il catalizzatore. Una bassa caduta di pressione attraverso il bruciatore secondario viene realizzata prevedendo una pluralità di passaggi assiali che presentano una resistenza relativamente piccola al flusso di gas. Le superfici dei passaggi sono rivestite con un materiale catalizzatore in modo da assicurare che eventuali reagenti non ossidati vengano ossidati.

Title: Pilota automatico
Inventor: ROVELLA TIZIANO
Filed: 1995-03-15
Abstract: L'idea consiste nell'inserire a dei prototipi di macchine elettriche giocattolo un sistema di guida elettronico. Questo sistema consente a tali prototipi di seguire una pista di qualsiasi forma costituita da semplice nastro adesivo di colore nero. Il prototipo sarà capace di percorrere rettilinei curve e incroci. Un sensore ottico rivela la differenza di riflessione di luce infrarossa tra pista e sfondo, (tavolo, pavimento, ecc.). Il prototipo sarà capace di seguire la pista anche al buio. La pista, costituita da normale nastro, adesivo, associa l'economia della realizzazione alla creatività del gioco. Tuttavia il dispositivo può anche essere impiegato per altre applicazioni come per esempio per la guida di macchine da lavoro o carrelli che devono percorrere sempre la stessa pista.

Title: Method of and apparatus for treating fluidised materials in a fluidised bed reactor
Inventor: HYPPANEN TIMO
IPC: F23C10/24
Filed: 1994-05-16
Abstract: Particles in a fluidized bed reactor (e.g. a circulating fluidized bed reactor) are discharged from the reactor chamber and then cooled (heat is recovered from them) in a processing chamber. This is accomplished in a particularly advantageous way by discharging the particles from the reactor chamber at a first level (e.g. through a non-mechanical seal or a classifying wall) into a lifting chamber. Upwardly flowing gas in the lifting chamber entrains the particles and lifts them into the processing chamber. After processing, the particles in the processing chamber are returned to the reactor chamber at level higher than the first level, at which point the pressure in the processing chamber is higher than the pressure in the reactor chamber. The particles may be classified in the lifting chamber by utilizing fluidizing gas to transport solid particles smaller than a predetermined size to the processing chamber while discharging larger particles from the bottom of the lifting chamber.

Title: Method and device for tightly fixing a piece of flexible tubing consisting of an elastomer material to a connecting part
Inventor: HASSELBRING BERND
IPC: F16L1/00
Filed: 2000-07-21
Abstract: The invention relates to a method for tightly attaching a piece of flexible tubing of an elastomeric material to a connecting part, especially for attaching air bellows for pneumatic springs to a connecting part with a clamping ring, which is radially pressed using a pressing tool. The force-displacement characteristic line (16) of the pressing tool is recorded while the clamping ring is being radially pressed, in order to carry out the method. This force-displacement characteristic line (16) is used to determine the lost force that is required in the pressing tool for the plastic deformation of the clamping ring and for overcoming the inner friction of the pressing tool. This lost force is used for adjusting the additional force resulting from the pressing tool being moved together in such a way that it corresponds to a predetermined force between the piece of flexible tubing and the connecting part. The invention also relates to a pressing tool for carrying out this method.
