  • Patent number: 8957382
    Abstract: The present invention relates to a method for slaving the activation of a set of infrared emitters of a sensor of venous networks to the presence of a living body between this set and an image acquisition means of the sensor. The method is characterized in that each infrared emitter (E) is activated if the presence of a part of the living body (CV) is detected by at least one presence detector (DP) which is associated therewith and each infrared emitter (E) is deactivated as long as the presence of a part of the living body (CV) is not detected.

  • Patent number: 8136441
    Abstract: Hydraulic machine, in particular hydraulic motor, comprising a casing, a differential piston (4) having a region of large cross section and a region of smaller cross section, which can slide with a reciprocating movement respectively in the casing and in a housing coaxial to, and of smaller diameter than, the casing, the piston separating two chambers of the casing and being provided at the location of its large cross section and its small cross section with sealing lips (48, 49) which are oriented in opposite directions and which face one another. The sealing lips (48, 49) are provided on detachable circular rings (50, 51), and the piston (4) is molded in one piece.

  • Patent number: 8132497
    Abstract: A hydraulic machine includes a casing with a body and a cover; a separation member which can make a reciprocating movement and defines two chambers; hydraulic switching elements including a distribution member; a compartment in the body of the casing connected to a pressurized-liquid inlet, and initiating elements including a pusher connected to the separation member, these initiating elements being able, at the end of the stroke, to cause a sudden change in the position of the switching elements, under the action of an elastic member to reverse the stroke. The distribution member has a distribution slide valve applied against a flat plate which is fixed relative to the body of the casing, the slide valve being able to slide in a fluid-type manner, without a seal, against the plate, which has orifices connected respectively to the chambers and to a liquid outlet orifice.

  • Patent number: 7975597
    Abstract: Hydraulic machine includes: a casing; a piston slidable therein and separating two chambers; hydraulic switching elements for supplying liquid to and for evacuating the chambers, including at least one connecting rod acting on a distribution member which can adopt two stable positions; and initiating elements having a pusher which, at the end of the piston stroke, can cause a sudden change in the position of the switching elements, under the action of an elastic member to reverse the stroke. Each end of the elastic member is secured to an articulation member respectively accommodated in a housing provided on the connecting rod and on another moving part, each housing being open in a direction substantially opposed to the direction of the force exerted by the elastic member, such that each articulation member can be removed from its open housing against the action of the force, thereby simplifying assembly and disassembly.

  • Publication number: 20070227961
    Abstract: The invention relates to a dosing device for introducing an additive (A) in to a main liquid flow (L) in a conduit comprising a reciprocating differential piston pump (2) which is used for collecting and dosing the additive (A) from a container (1) and comprises a first inlet (7) for receiving the main liquid flow which ensures the pump actuation, a second inlet (8) for collecting the additive and an outlet (9) for mixing the additive and the main liquid. The inventive device comprises a Venturi (10) disposed in the conduit and the pump (2) connected in parallel position with respect thereto, wherein the first inlet (7) of the pump is connected to the Venturi input (11) and the outlet thereof is connected to the Venturi throat (12).
