Abstract: Radar proximity fuse (1) adapted to receive an echo radar signal (s_rx) produced by the reflection on a target (T) of a transmitted radar signal (s_tx), the transmitted signal (s_tx) comprising a sequence of M impulses coded with a phase code (p_cd). The radar proximity fuse (1) comprising: a radiofrequency analog receiving front end (15) for receiving the echo radar signal (s_rx), adapted to provide in output a baseband signal starting from the echo radar signal (s_rx) received; an analog to digital converter (12) positioned at the output of the analog receiving front end (15) adapted to sample the baseband signal to obtain in output a sequence of digital samples (d_rx); a digital processing block (20) comprising a plurality of digital processing channels (C1, C2, . . . CN) each associated to a respective range gate and each adapted to receive in input said sequence of digital samples (d_rx).

Abstract: A pump includes a body, an actuating shaft, on which at least a first impeller and a second impeller are axially mounted, a fluid intake duct and a fluid delivery duct. The pump further includes front and rear chambers, first and second volutes, first and second discharge orifices and a channel inside the body for throughflow of fluid to the second impeller.

Abstract: Pump comprising a body (10), an actuating shaft (1) on which at least a first impeller (21a) and a second impeller (21b) are coaxially mounted, each being housed in a respective front chamber (15a) and rear chamber (15b) respectively connected to a fluid intake duct (11) and a fluid delivery duct (13), in which said front chamber (15a) is delimited by said body (10) and by an interstage body (16), said rear chamber (15b) is delimited by said interstage body (16) and by a shield (23), said interstage body has two volutes (22a, 22b) respectively associated with the corresponding first impeller (21a) and second impeller (21b), a first discharge orifice (16a) connecting the volute (22a) of the first impeller (21a) to the exterior, a second discharge orifice (16c) connecting the volute (22b) of the second impeller (21b) to the delivery duct (13), inside said body (10) there being formed a channel (17) for the throughflow of the fluid from said first chamber (15a) to the means for supplying the fluid to the second

Abstract: Volumetric blower comprising an internally hollow body (11) for defining a compartment (12) which is placed in communication with an intake manifold (30) and a delivery manifold (31) and which has, arranged inside it, two rotors (20) which are parallel to a longitudinal axis (X—X) of the blower, counter-rotating and shaped in the manner of lobes (21) having a correlated profile and which are designed to produce, together with the internal wall (11a) of said compartment, the periodic formation of a chamber (40) containing the fluid to be conveyed to the delivery manifold (31), the opposite openings in the longitudinal direction of said compartment (20) being closed by an associated cover (50), wherein the internal surface (51) of said covers (50) has, formed in it, at least one duct (52;152) arranged, with respect to the longitudinal axis (X—X), on the side corresponding to the delivery manifold (30) so as to allow connection of said chamber (40) to the delivery manifold itself and designed to be c
