摘要： An axial-flow pump combined with an electric motor coaxially arranged therearound. The rotor (1) and stator (2) are common to both the electric motor and the pump. The rotor comprises a central tubular portion (11) defining a central channel (14) with a wall (15) provided with blades (16). The blades preferably do not extend as far as the channel axis (3) so that they define a central free area therealong. The outer portion of the rotor (1) has pairs of permanent magnets (24, 25) with stator coils (9) therebetween. The coils are actuated and deactuated by an electronic switching device (28) controlled by sensors (36, 37) for sensing markings on the rotor. The length of the rotor is smaller than its outer diameter. Said pump may be used to pump liquids or gases and drive vehicles, particularly submarines.

摘要： The roller skates comprise a frame (3) provided with two or more rollers aligned one behind the other in a common medial plane. Each roller (4, 5) is configured like a narrow bobbin with two circular flanges provided with bandages and a recessed central hub mounted inside a ball bearing. This ball bearing is mounted in an orifice of a central plate (24) of the frame, said plate carrying also a front stop (6) and a rear stop (7). A member absorbing the shocks in the radial direction is interleaved between the ball bearing and the plate (24). Preferably, the frame (3) of the roller skates is fitted with a leg support (1) which is hinged with respect to a transverse axis (Y) at the ankle. A brake for braking the rollers (4, 5) may be mounted on the central plate (24) of the frame. Due to the particular shape of the rollers, their bearings and the frame are lighter.

摘要： Le patin comporte un châssis (3) muni de deux ou plusieurs roulettes alignées l'une derrière l'autre dans un plan médian commun. Chaque roulette (4, 5) a la forme d'une bobine étroite, avec deux joues circulaires munies de bandages et un moyeu central évidé monté à l'intérieur d'un roulement à billes. Ce roulement est monté dans un orifice d'une plaque centrale (24) du châssis, cette plaque portant également un butoir avant (6) et un butoir arrière (7). Un organe absorbant les chocs en direction radiale est intercalé entre le roulement et la plaque (24). De préférence, le châssis (3) du patin est équipé d'un support de jambe (1) qui est articulé par rapport à un axe transversal (Y) au niveau de la cheville. Un dispositif de freinage des roulettes (4, 5) peut être monté sur la plaque centrale (24) du châssis. Grâce à la forme particulière des roulettes, leurs paliers et le châssis sont allégés.
