Abstract: The invention refers to a process for the obtainment of a catalyst useful in the isomerization of light para­ffins, fundamentally based on acid treatment of a synthe­tic mordenite at temperatures between 40 and 100º C follow­ed by treatment with steam-air at temperatures between 300 and 600º C which makes it possible to optimize the SiO₂/­Al₂O₃ framework ratio and the amount of extraframework aluminum of the zeolite. The mordenite thus obtained is mixed with an inorganic refractory oxide such as Al₂O₃ and a metal of group VIII, basically Pt, is added in an amount between 0.1 and 0.5 % by weight referred to the final cata­lyst. 
     The catalyst has been tested in the isomerization of light refinery fractions (C₅ and C₆) and has a high activity and selectivity of branched isomers with a low production of gases and a high octane number for the light gasoline ob­tained.

Abstract: Le moteur décrit, qui est conçu pour être utilisé dans des opérations de forage est constitué par un moteur à ailettes et comprend un carter généralement tubulaire (1, 2) et un rotor (4) monté en rotation dans le carter et espacé radialement de lui, de façon à définir une chambre (18) entre eux. Le carter (1, 2) est pourvu d'organes d'entrée et de sortie angulairement espacés (19, 20), permettant l'admission du fluide de travail pressurisé depuis un conduit d'entrée (19a) se trouvant dans le carter (1, 2) jusqu'à dans la chambre et l'émission de ce fluide depuis l'intérieur de la chambre, vers un conduit de sortie (20a) séparé du conduit d'entrée (18) par une paroi (21). Le carter (2) comporte une paroi s'étendant généralement radialement (3), qui s'étend essentiellement en contact avec le rotor (4) en une position angulaire située entre les organes de sortie et d'entrée (20, 19). Le rotor (4) comprend plusieurs ailettes angulairement espacées (15). La paroi s'étendant radialement (3) ou l'ailette (15) est déplaçable depuis une disposition saillante s'étendant généralement radialement en contact essentiellement étanche avec le rotor (4) ou le carter (1, 2), respectivement, vers une disposition généralement repliée, lorsque l'organe en question traverse l'autre organe, à savoir la paroi s'étendant radialement (3) ou l'ailette (15). Les ailettes (15) et les organes d'entrée et de sortie (19, 20) sont formés, conçus et disposés angulairement entre eux, de sorte qu'un courant de fluide pressurisé dans la chambre (18) agit contre un côté amont (15c) d'une première ailette (15') de façon à faire tourner le rotor, tout en permettant l'évacuation du fluide depuis son côté aval (15e), jusqu'à ce que l'ailette (15') traverse l'organe de sortie (20) et qu'une seconde ailette (15'') traverse l'organe d'entrée (19), le processus pouvant alors se répéter. La présente invention se rapporte également à des appareils de forage et de carottage équipés d'un moteur à ailettes de la présente invention.

Abstract: The present invention relates to a scooter-type vehicle comprising a rear body (7) a housing box (8) disposed in the rear body (7), and a unit swing type engine (4) provided under the rear body (7), wherein a reference line (X₁-X₁) is established on the upper side profile of the unit swing type engine (4) so that the upper end of the upper side of the unit swing type engine (4) is placed under the reference line (X₁-X₁). It is therefore sufficient to consider the relation between the reference line and the bottom of the housing box (8) during oscillation of the unit swing type engine (4). It is thus possible to simplify the locus and range of the oscillation and make attempts to increase the stroke amount of a rear cushion unit (18), decrease the height of a seat (5) and increase the volume of the housing box (8). In addition, since the upper end of the upper side of the unit swing type engine (4) is placed under the reference line (X₁-X₁), it is possible to avoid the interference with the vehicle body (7) and improve the workability when the unit swing type engine (4) is attached to and detached from the vehicle body (7).
