  • Patent number: 10989042
    Abstract: Systems and methods to cover sensitive areas of downhole tools including a downhole tool having an outer surface including a first position and a second position on the outer surface of the downhole tool, the outer surface having a sensitive area, a downhole sensitive element positioned along the outer surface of the downhole tool at the sensitive area, a movable cover operatively connected to the downhole tool and movable relative to the sensitive area, a control unit configured to generate an activation signal, and an activation mechanism operable in response to the activation signal, the activation mechanism configured to move the movable cover relative to the sensitive area from the first position to the second position, wherein the movement of the movable cover from the first position to the second position one of increases or decreases a portion of the sensitive area covered by the movable cover.

  • Patent number: 10774615
    Abstract: An apparatus for controlling fluid flow in a wellbore may include a valve disposed along a drill string. The valve includes a valve body having an internal chamber, a plurality of ports formed in the valve body, a ball disposed in the internal chamber, and an actuator operatively connected to the ball. The ball includes at least one flow bore. The actuator shifts the ball into at least a first position wherein the flow bore is in fluid communication with at least two of the plurality of ports, and a second position wherein the flow bore is isolated from at least one of the plurality of ports. A related method includes conveying a drill string having the above-described valve along the wellbore and controlling a flow of fluid by shifting the ball using the actuator.

  • Patent number: 9963010
    Abstract: The invention relates to an air conditioning system for conditioning the air of a passenger compartment of a motor vehicle, including an outlet section for diverting at least a portion of an air-mass flow circulating in the air conditioning system into the environment of the motor vehicle, a housing for directing the air-mass flow, wherein at least one fan for conveying the air-mass flow is designed within the housing, as well as a coolant circuit for tempering components of the motor vehicle, in particular, components of a power train, having a coolant-air-heat exchanger for transferring heat from the coolant to an air-mass flow.

  • Patent number: 7284394
    Abstract: The invention relates to an inner heat exchanger for high-pressure refrigerants which is also used as an accumulator or refrigerant collector in air conditioning circuits. The inner heat exchanger includes an outer cylinder arranged and an inner cylinder arranged therein. The inner cylinder is designed as a bent flat sheet or tube with microchannels for refrigerant under high pressure. The liquid refrigerant under low pressure is collectable within the inner cylinder. Between inner cylinder and outer cylinder are formed channels in which the vaporous refrigerant under low pressure flows from a low-pressure inlet to a low-pressure outlet.
