  • Patent number: 8726650
    Abstract: A hydraulic manifold pump comprising a housing in which is located a first hydraulic circuit and a second hydraulic circuit. A bidirectional motor connectable to the first hydraulic circuit and the second hydraulic circuit, the bidirectional motor being able to activate the first hydraulic circuit when operable in a first direction, and being able to activate the second hydraulic circuit when operable in a second direction. The hydraulic manifold pump further compromises a hydraulic actuator having two hydraulic chambers being connectable to the first hydraulic circuit and to the second hydraulic circuit, and both the first and second hydraulic circuits being connected to and able to vent into a fluid reservoir.

  • Publication number: 20110241309
    Abstract: There is provided a bearing holder comprising a first side, orthogonal to a head tube axis when the bearing holder is used in conjunction with a head tube of a bicycle, adapted to receive a bearing, and a second side, opposed to the first side, adapted to be removeably secured to a head tube of a bicycle, the bearing holder being adapted to axially position the bearing about the head tube. The bearing holder is mounted to the top end of the head tube of the bicycle and the fork tube is engaged to the bearing provided atop the bearing holder. The height of the bearing holder (or a spacer if the bearing holder sits onto such a spacer) determines the elevation of the handlebar connector and thus of the handlebars with respect to the head tube thereby permitting the adjustment of the elevation thereof.

  • Patent number: 7546879
    Abstract: The invention relates to a device for control of the flow through a production tube placed in an oil well. The device comprising a portion of the production tube provided with through orifices and protection equipment for providing resistance to wear by erosion. The protection equipment comprises several add-on sectors assembled around the portion of the tube. Each add-on sector provided with an associated inner stiffener penetrating into the portion of the production tube through at least one through orifice. At least one of the add-on sectors provided with at least one opening extending through the sector and its associated inner stiffener.

  • Patent number: 7086471
    Abstract: The invention relates to apparatus for controlling the flow rate of a fluid in tubing (4), said apparatus (5) comprising at least one hole (7) passing through the wall of said tubing and a moving shutterjacket (8) mounted to engage said hole. According to the invention, said apparatus further comprises deflector means (9) covering said jacket and said hole so that said deflector means directs the fluid through the wall of said tubing.

  • Patent number: 6499541
    Abstract: In downhole apparatus for an oil well, components (26) are installed in tubes (28) received in a space defined between an outer case (20) and an inner length of cylindrical production column (24) that is eccentric relative to the case (20). Each tube (28) is fixed at one end to an interconnection box (30) that is also received in said space, and that has electrical conductors passing therethrough. The tubes (28) are fixed to the box (30) by welding, and the ends of the tubes remote from the box are closed by plugs that are welded on.

  • Patent number: 6364023
    Abstract: An actuator (14) designed to remain without maintenance down a well for a prolonged period comprises at least one sealing bellows (44) and preferably a compensation bellows (46) between the well fluid and an internal chamber (30) that is full of hydraulic fluid. The bellows (44, 46) serve to make it possible either to omit dynamic elastomer gaskets altogether or at least to protect them from the well environment. The actuator (14) e.g. of the electromechanical type, can serve in particular to control a valve (12) having an opening of adjustable size. Both bellows (44, 46) are advantageously made of stainless steel. They can be mounted end-to-end or they can be quite separate.
