Abstract: L'invention porte sur une turbine (21, 121) et sur un procédé pour extraire de l'énergie à partir d'un fluide s'écoulant le long d'un canal de fluide (4, 104) d'un système de fluide. La turbine a un trajet d'écoulement (30, 130) avec une entrée (32, 132) en communication avec le canal de fluide. Un rotor (23, 123) est disposé dans le trajet d'écoulement, et peut tourner autour d'un axe de rotation (R) sous l'action d'un fluide s'écoulant le long du trajet d'écoulement. L'axe de rotation du rotor est oblique par rapport à un axe s'étendant le long du canal de fluide. La sortie (34, 134) du trajet d'écoulement peut renvoyer du fluide au canal de fluide. La turbine peut également comporter un agencement de commande d'écoulement (170) de façon à faire varier l'écoulement de fluide le long du rotor et à éviter au rotor d'être endommagé. L'invention permet la génération ou l'extraction d'énergie à partir d'un fluide s'écoulant le long d'un canal de fluide par la turbine. Le rotor peut être positionné de façon écartée par rapport au canal de fluide, de façon à ne pas obstruer le canal de fluide. De plus, par l'orientation oblique du rotor et des axes de canal, la turbine peut être positionnée sous un agencement compact autour du canal de fluide ou au voisinage de ce dernier, et, par conséquent, la turbine peut être reçue à l'intérieur des dimensions d'appareils existants, comme cela est requis, par exemple, dans des applications au pétrole et aux gaz.

Filed: 2016-03-31
Abstract: A rotor for a permanent magnet machine comprises first and second axially successive rotor sections (102, 103) each comprising permanent magnets generating magnetic field having a pole pitch (pp). The rotor comprises a first coupling system (106) for connecting the first rotor section to a shaft (1 15) and a second coupling system (1 19) for connecting the second rotor section to the shaft or to the first rotor section.

Title: Inspection system
Inventor: FAN XUPING
IPC: B66C23/18
Filed: 2017-10-05
Abstract: The present invention relates to an inspection system. The inspection system comprises a base, a boom lifting mechanism provided on the base, and a boom mounting a detector. The boom lifting mechanism includes at least two support arms arranged sequentially. The at least two support arms include a base arm and a distal arm. The base arm is connected to the base, the boom is mounted on the distal arm, the inspection system has a scanning state and a transporting state, and two adjacent support arms of the at least two support arms are rotatably connected so that the height of the boom in the scanning state is different from that in the transporting state. The boom lifting mechanism of the inspection system of the present invention lifts the boom by rotatably connecting two adjacent support arms, and presents less required driving force compared to the lifting of the boom directly in a vertical direction in the prior art. Thus, there is less weight of the driving mechanism for driving the lifting of the boom, so as to reduce the self-weight of the inspection system.

Title: Expandable sleeve valves and installations thereof
Inventor: NELSON DARRELL
IPC: F16K17/02
Filed: 2017-11-14
Abstract: A valve features an outer housing, in which there are provided inlet and outlet channels respectively reaching into the housing from inlet and outlet openings thereof. The two channels are axially closed at adjacent inner ends thereof, but feature perforated circumferential walls. A resiliently expandable sleeve is disposed around the circumferential walls in a position normally overlying the perforations, while leaving a gap between the sleeve and inner surfaces of the housing. A charging port communicates with the gap to enable pressurization thereof. Pressurization of the gap normally holds the sleeve tightly over the perforations to prevent flow from one channel to the other. When pressure in the inlet channel exceeds the pressure in the charging chamber, the sleeve radially expands from the circumferential walls of the channels to uncover the perforations and allow fluid to flow between the channels.
