A protective cover (10) is disclosed that can be interchanged among a variety of baby seats. It includes a canopy (11) and a sealing element (22) that can interchangeably and flexibly seal around a variety of baby seats. It may also contain a removable hood (20) that may shield a portion of an insect resistant mesh (15) so that a side mesh (15b) remains open for air and viewing of the occupant under the protective cover (10). Furthermore, the hood (20) may be attached at an approximate midpoint (26) of the canopy (11) to allow versatility in deploying the hood in a rearward direction and fastening the hood with attachment element (38). Likewise, the hood (20) may be folded in a forward direction and attached with attachment element (38) to a forward contour of a baby seat. The protective cover may include a protective foot shield (14) located under the hood (20) that may protect, for instance, feet of an occupant from a stinger or biting proboscis of a flying insect when the feet may touch the inside surfaces of the cover. Another feature of the present invention may include the ability of the present invention to be folded to a reduced state for easy storage and held in the reduced state by an integral restraining element which could be the hood (20). Another feature could be an inclement weather filtering configuration of mesh that could be located on the side to filter light, for instance, to a reduced level for the occupant's comfort.

A retrievable flow control device comprising a housing configured to sealably couple with a completion component. The housing may comprise a first port and a second port establishing a fluid pathway. The fluid pathway may regulate a fluid flow as the fluid flow passes through the fluid pathway. The housing may further comprise a coupling mechanism configured to releasably couple with a corresponding feature of the wellbore completion. The downhole flow control device may be configured to be retrievable independently of the completion component. The flow control device may comprise a check valve in the fluid pathway in order to substantially constrain the fluid flow to a single direction. In some cases, the flow control device may be configured to couple with a side pocket. In other cases, a concentric flow control device may be configured to couple with a screen base pipe, tubing, or stinger.

An apparatus for deploying pipe string is disclosed. The apparatus comprises a mast; an articulated stationary table to which the mast is affixed; a stinger affixed to the stationary table to articulate with the mast; and a pipe erector operatively connected to the mast.

The invention relates to a control method and a system of a helicopter rotor, which belongs to the technical field of helicopter operation. The control method is characterized in that the distance changing of a blade is realized by adopting an actuator positioned on the stinger of each propeller boss to drive a flap positioned at the rear edge of the blade, so as to realize the control of a rotorsystem. The system comprises a demountable flap (1) installed at rear edge of the blade, torque soft propeller bosses (14), an actuator (13) installed on the stinger of torque soft propeller bosses, a flap control mechanism (1) with one end being connected with actuator (13) and the other end thereof being connected with the flap (1), and a test control system (59). The control method and the system have the advantages that the screw piston of each blade can be independently controlled, the structure is simple, the weight is light, the controllability is good, and the reliability and the security are high.

The present invention relates to an apparatus for continuously laying a pipeline on the floor of a body of water from a pipelaying vessel, said apparatus comprising: a generally cylindrical reel with an axis upon which the pipeline is wound, a stinger provided at the stern of the vessel for guiding the lowered pipeline, launch means for the controlled lowering of the pipeline over the stinger of said vessel and into the body of water. This apparatus further comprises a frame supporting the reel and the launch means, adapted to be moveable with respect to the vessel in the longitudinal direction of the pipeline, and a tension device to be mounted between the frame and the vessel, adapted to control the pipeline tension in a predetermined tension range during pipelaying.

Methods and apparatus are provided for an exhaust duct having an externally replaceable acoustic liner. The exhaust duct includes a forward section that is configured to be axially coupled with a bulkhead collar on the aircraft, a body section that is coupled to the forward section and a stinger cap that includes the replaceable acoustic liner. The replaceable acoustic liner is configured to be slideably received by the body section.

A gas piston system for a firearm includes a gas block having a port in communication with the barrel port and an exhaust tube. The exhaust tube has: a head at least partially disposed in the gas block and having a port in fluid communication with the gas block port; a body extending from the head toward a muzzle of the firearm; and a channel extending from the exhaust tube port through the body. The gas piston system further includes a driver movable relative to the gas block between a forward and rearward position and having: a piston slidable along the gas block; a stinger closing the channel in the forward position and opening the channel in the rearward position, and an operating rod operable to push the bolt carrier assembly away from the barrel.

A method and apparatus for characterizing the response of an electronic stethoscope. The sensor of the electronic stethoscope is held in contact with a test surface of a phantom. A shaker, which is coupled to a stinger rod that extends inside the phantom, is driven to produce internal vibrations in the phantom. Surface motion of the test surface of the phantom is measured using a surface accelerometer coupled to the test surface. Vibrations from the phantom are detected and an electric signal based on the detected vibrations is generated with the electronic stethoscope. A surface transfer function is calculated based on the measured surface motion and the electric signal to characterize the response of the electronic stethoscope.
