Roncuzzi & Associati S.r.l.

A reactor (1) for heterogeneous catalysis processes in which a containment shell (10) is delimited internally by an elongated cavity (11); provided with an operating station (12) arranged in an intermediate position internally delimited by an air space (14) peripherally delimited by a first wall (140) having geometric shape similar to that of the cavity (11); at least one monolithic body (19) contained inside said air space (14), electrically conductive in order to be electrically heatable by Joule effect so as to trigger and effectively control a chemical transformation reaction of the mixture; each monolithic body (19) being delimited peripherally by a second wall (190); the second wall (190) being shaped in a geometrically conjugate manner with the first wall (140).

Hub (1) for connecting a front wheel (W) of a vehicle to an axle (A) of a stub axle (S) rotatably through at least one rolling support unit (U); said hub (1) comprising an elongated body (10) extended along a second central axis (AX2) between a respective first annular end (12) and a respective second annular end (14), both concentric to said second axis (AX2); said first end (12) being provided with coupling means (120) for coupling of said wheel (W); said elongated body (10) having internally an axisymmetric cavity (16) concentric to said second axis (AX2) engageable longitudinally by said axle (A); said cavity (16) having, starting from the side of said second end (14), a second cylindrical section (160) coaxial to said second axis (AX2) that measures a fourth diameter (D4) for housing, in use, said support unit (U); the cavity (16) having on the side of the first end (12) a first section (164) delimited internally by an axisymmetric surface of a lower diameter to said fourth diameter (D4) to act as an axial abutment for the unit (U); an annular cover (2) being carried by the second end (14) provided with axial abutment means (166) concentric to the second axis (AX2) and engaging the second section (160) to act as an axial abutment of said unit (U) on the opposite side to the first section (164).

Screening device(1) comprising a tubular box-shaped body (100) having two opposing sides (105') (105'') connected by an opposing first plate (103') and an opposing second plate (108) that delimit a first opening (102) and a second opening (104) engaged fully by a plurality of screening members (106') (106''); each screening member (106') (106") comprising a shaft (1060) that carries a plurality of moving members (1062) arranged spaced between the first and second sides (105') (105'') and provided with a plurality of lobes (10620) uniformly distributed peripherally; an actuator (110) being carried by the box-shaped body (100) to carry in rotation the screening members (106') (106'') so that, in use, each screening member (106') (106") envelopes an ideal first cylinder (C1) of a determined diameter, through the lobes (10620) of the respective moving members (1062); the set of the first cylinders (C1) envelopes an ideal second cylinder (C2) contained fully inside the box-shaped body (100).
