Title: Triple furnace for brazing aluminium parts incorporating cavities in a salt bath with argon gas
Inventor: VISCONTI BREBBIA GIORGIO
IPC: F23M/
Filed: 1994-08-12
Granted: 1997-07-18
Abstract: Triple furnace for brazing aluminium parts incorporating cavities in a salt bath with argon gas where by means of a vertically adjusted device located within them the parts which are to be brazed are heated only therein and then brazed thus avoiding the use of two furnaces and in which in order to obtain repeated and rapid lighting and relighting of the furnace the latter is provided with three sources of heat as a triple furnace in which the salt is contained in a vessel of refractory material which is able to hold it and then passed to a second highly thermally insulated vessel with an electric resistance located between the two vessels which heats the salt in order to cause it to melt and where in order to obtain all this in a short time a parabolic heater of great power is fixed to the vertically adjustable device above the salt and then removed once the furnace has started, and finally some nickel electrodes immersed in the salt through which current passes. In addition to this, in order to keep the parts which are to be brazed together, weights which are also provided with levers in order to achieve large forces with small masses are used instead of expensive welding points in order to prevent the salt from entering into combination with the sheets at the junction points, appreciably reducing their mechanical strength. In addition to this when brazing parts provided with cavities, instead of causing the salt to circulate within them an inactive gas which has been preheated in a coil is caused to circulate. <IMAGE>

Abstract: Il trovato si riferisce ad una cerniera elastica del tipo comprendente un corpo cavo allungato che contiene un mezzo elastico disposto fra l'estremità con appoggio di un perno che lo attraversa assialmente e mezzi di contrasto bloccati nello stesso corpo. Il perno attraversa i mezzi di contrasto sviluppandosi da un primo elemento di cerniera ai quali è imperniato un secondo elemento di cerniera.La cerniera si caratterizza per il fatto che i mezzi di contrasto comprendono due elementi tubolari allineati in appoggio l'uno contro l'altro con due loro corrispondenti superfici inclinate rispetto all'asse.Un primo elemento, su cui è in appoggio il mezzo elastico presenta minimo gioco col perno mentre un secondo elemento presenta un foro di passaggio allargato ed è alloggiato con una sua porzione periferica; in una predisposta sede laterale del corpo.
Patent IT-1249467-B (IT)
Inventor: RAGNI LINO
IPC: G10H1/34
Filed: 1991-11-14
Granted: 1995-02-23
Abstract: Beneath each key and carried by the keyboard support there is a basically round-shaped elastic or elasticized element, the base of which lies on the keyboard support, such a round-shaped surface, which may be achieved by hot-pressing a rubber sheet, and on top of which there is a collar the aim of which is to provide a certain resistance to the key, thus distributing the deformation resistance to the key, thus distributing the deformation caused by the pressed key over the entire surface of the round-shaped element. In other words, the top collar, under the effect of the pressed key, moves parallel to itself, thus causing the uniform deformation of the entire rubber element. The keyboard support consists of a board or plate on which a layer of plastic material is injected in such a manner as to cover the edges and the ends of the board or sheet, while leaving the middle parts uncovered, thus forming a sort of grid.

Title: Meccanismo di sterzo esatto e meccanismo di collegamento del corpo vettura alle ruote
Inventor: ALLEGRINI FRANCESCO
IPC: B60G/
Filed: 1994-06-15
Granted: 1997-06-16
Abstract: Il meccanismo di sterzo esatto ed il meccanismo di collegamento del corpo vettura alle ruote trovano impiego nel campo degli autoveicoli.Scopo del meccanismo di sterzo esatto è consentire che, durante i cambiamenti di direzione, tutte e quattro le ruote siano animate di moto esclusivamente rotatorio intorno ai rispettivi assi che devono passare per il centro d'istantanea rotazione dello stesso autoveicolo. Pertanto, in ogni configurazione assunta dal meccanismo di sterzo, le ruote rotolano senza subire strisciamenti laterali.Lo scopo del meccanismo di collegamento del corpo vettura alle ruote consiste: nello impedire che angolo e posizione delle ruote siano influenzati dalla posizione assunta dal corpo vettura rispetto alle ruote; nel mantenere tutte le ruote ortogonali al terreno anche quando l'autoveicolo percorre una curva e nel provocare maggiore e uguale compressione di tutte le molle degli ammortizzatori al fine di ottenere maggiori e uniformi condizioni di aderenza di tutte le ruote.

Patent TW-215086-B (TW)
IPC: B01J8/06
Filed: 1992-07-07
Granted: 1993-10-21
Abstract: An improved process for the manufacture of maleic anhydride by catalytic oxidation of a nonaromatic hydrocarbon having at least four carbon atoms in a straight chain, in which a gas containing oxygen and hydrocarbon is passed through a fixed catalyst bed in a tubular reactor. The activity of the catalyst bed is graded in such manner that the reactor can be operated at an initial (feed gas) hydrocarbon concentration of over 1.5% by volume, an integrated average temperature difference between gas and cooling fluid of at least about 15 DEG  C. over that portion of the bed in which the gas temperature exceeds the cooling fluid temperature, and a productivity of at least about 5.0 lbs. maleic anhydride per hour, without the temperature difference between the gas and the cooling fluid exceeding 80 DEG  C. at any point in the catalyst bed during the course of the reaction. Preferably, the catalyst activity and the gas permeability of the bed vary in the direction of gas flow so that both the catalyst activity and the pressure drop per unit distance are lower in a critical region, where the combination of temperature and hydrocarbon concentration could otherwise cause the reaction to proceed at an excessive rate, than they are in a region of low temperature and low hydrocarbon concentration. Significant and unexpected improvement in reactor performance is achieved by the combination of a graded catalyst charge and incorporation of a catalyst modifying organophosphorus compound in the hydrocarbon feed.
