A line sensor deployment and recovery apparatus and system with integrated level-wind. In one embodiment, a line deployment and recovery apparatus with an integrated level-wind, comprising a reel, having an external surface with helical grooves, wherein the grooves facilitate a line; a motor configured to axially rotate the reel; a level-wind shuttle, further comprising: a fairlead configured to selectively feed the line into the helical grooves, or deploy the line from the helical grooves; a shuttle finger configured to align the shuttle with the helical grooves and receive a driving force from the reel's rotations to drive the shuttle; and a shuttle track, oriented parallel to the drum and fixed in a offset position form the helical grooves at an operable track height, configured to facilitate linear traversal of the shuttle along the reel.

The invention relates to a reel for a winder, comprising: a mandrel (10) extending around an axis of rotation (X) of the reel, a plurality of pairs of lateral arms (20a, 20b) extending on both sides of the mandrel (10), together acting as flanks defining, between them, a winding volume for the link,
said reel being characterised in that it comprises a closed flange (40) attached to the arms (20a) constituting one of said flanks, said flange having a thickness of between 10 and 40 mm.

Various embodiments of the present disclosure provide a rotorcraft-assisted system and method for launching and retrieving a fixed-wing aircraft into and from free flight. The launch and retrieval system includes a modular multicopter, a storage and launch system, an anchor system, a flexible capture member, and an aircraft-landing structure. The multicopter is attachable to the fixed-wing aircraft to facilitate launching the fixed-wing aircraft into free, wing-borne flight. The storage and launch system is usable to store the multicopter (when disassembled) and to act as a launch mount for the fixed-wing aircraft by retaining the fixed-wing aircraft in a desired launch orientation. The anchor system is usable with the multicopter, the flexible capture member, and the aircraft-landing structure to retrieve the fixed-wing aircraft from free, wing-borne flight.

The invention discloses a rigid-flexible coupling mechanism with variable rod length for fibre bundle tension control. In the transmitting process, the fibre bundle passes through the front guide roller, the tension regulating roller and the back guide roller sequentially. The front and back guide rollers have fixed positions, while the tension regulating roller has an adjustable position to regulate the fibre bundle tension. The invention uses the variable rod length rigid-flexible coupling mechanism with a combination of a servo motor and an electric actuator in a dual drive control mode, which can choose to use either a four-rod fixed length mechanism or a five-rod variable length mechanism to regulate the tension under different working conditions. This provides a more flexible control method, increases the regulating range of fibre bundle tension, improves the system response speed and regulation accuracy, and effectively avoids the wear of fibre bundle caused by tension fluctuations.

The invention relates to a device for winding/unwinding a link adapted to transporter a fluid or transmit energy and/or signals, comprising: a reel (2) adapted to receive said link in wound form, a hollow through shaft (3) adapted to the passage of said link or fluid between a rotating joint and the reel, said hollow shaft (3) being integral with the reel (2) in order to drive said reel in rotation about a longitudinal axis (X) of said shaft, at least one permanent magnet synchronous direct drive motor, comprising a stator carrying windings (10) adapted to be electrically three-phase powered and a rotor carrying the permanent magnets (11) facing windings (10) of the stator.

A threadlike adhesive sticking apparatus of the present invention includes, a nozzle comprising a pressing unit configured to press a threadlike adhesive against an object, a nozzle displacement unit that is attached to the nozzle and is configured to displace the nozzle by being displaced in a pressing direction, and an absorption mechanism configured to absorb a displacement of the nozzle with respect to a displacement of the nozzle displacement unit in the pressing direction.

A cable dispenser system has a container, a dispensing panel formed on the container, a main dispensing opening formed on the dispensing panel, and a dispenser opening insert mounted to the main dispensing opening. The dispenser opening insert has a lid, and a lid base. The lid covers the lid base. A cable is retained in the container. The main dispensing opening is configured so that the dispensing panel has a first grab area. The first grab area is sandwiched between a first lid retainer and the lid base. The first grab area and the lid base are flat and oriented as layers.
