An earphone case includes a shell, a rotating drum received in the shell, a driving assembly coupled to the rotating drum and configured for rotating the rotating drum, and a back cover latchable with the shell and receiving the driving assembly in a receiving space defined therein. The rotating drum is driven by the driving assembly to rotate to wind a wire of at least one pair of earphones.

The patent discloses a winding device with a speed regulating mechanism. The winding device with a speed regulating mechanism includes a device body and a winding wheel installed on the device body. The speed regulating mechanism is arranged on one side of the winding wheel and includes a transmission gear set and a speed regulating shifting rod. The transmission gear set includes a sliding output gear and a speed regulating transmission member. According to the winding device with a speed regulating mechanism, the speed regulating mechanism is installed in the winding device, through the regulation of the speed regulating shifting rod, the transmission efficiency of a water turbine can be changed, and the regulation of various winding speeds can be achieved. Moreover, an idling function can be fulfilled after an output shaft is pulled through a handle, which makes the winding wheel suspend moving.

An apparatus comprising a mobile carrier operable for transporting a reel of oilfield tubing across ground. The mobile carrier comprises a frame comprising a first frame portion, a second frame portion, and a central frame portion extending between the first and second frame portions. The first, second, and central frame portions define an opening for receiving the reel. The mobile carrier also comprises a locking mechanism operable to engage and rotate the reel within the opening, and a plurality of wheels supporting the frame on the ground. The plurality of wheels comprises a plurality of first wheels operably connected to the first frame portion and a plurality of second wheels operably connected to the second frame portion. The opening interposes the plurality of first wheels and the plurality of second wheels.

Provided is a winding device configured so that the entirety of the device can be thinned and looseness of an elongated member can be reduced. In a winding device 1A, a flat motor 2 is used as a motor, and a spool 3 and a magical planetary gear mechanism 4 are formed flat along an extending XY plane of the flat motor 2. Thus, the entirety of the device can be configured flat, and can be thinned. Moreover, the magical planetary gear mechanism 4 prevents rotation of the spool 3 by external force, and therefore, looseness of the elongated member can be reduced.

An apparatus and method for converting the digging mechanism of a digger vehicle into a spooling mechanism is disclosed. An attachment assembly may be attached to a spool and to an auger drive shaft of the digger vehicle to create the spooling mechanism. The spooling mechanism may function by the auger drive shaft providing rotational force that gets translated to the spool through the attachment assembly to rotate and wind or unwind wire.

A system includes a frame and a first pair of rollers coupled to a first side of the frame. The first pair of rollers is configured to support a first end of a pipe reel. The system also includes a first cradle disposed longitudinally between the first pair of rollers and a second pair of rollers coupled to a second side of the frame. The second pair of rollers is configured to support a second end of a pipe reel. The system also includes a second cradle disposed longitudinally between the second pair of rollers, a pipe guide coupled to a third side of the frame between the first and second sides, a pipe brake coupled to the frame, and a pipe re-spooler coupled to the frame.

A strap length adjusting apparatus includes first and second stationary plates and a middle plate disposed between them. The middle plate can rotate relative to the first and second stationary plates. A biasing device is linked to first and second coupling members between the middle plate and the first plate. The biasing device can either couple the middle plate to the first plate or decouple the middle plate from the first plate. When the first and middle plates are decoupled from each other, the middle plate can rotate with respect to the first plate, and a strap partially wound about a rod that extends from the middle plate, can wind about the rod either clockwise or counterclockwise so as to continuously change a length of the strap that extends away from the rod.

The cover delivery device (e.g., for use in selectably covering a watercraft) can include a first mobile support assembly, a second mobile support assembly, a drive shaft, and a cover carrier mechanism. The first mobile support assembly is mounted to and configured for movement along a first rail. The second mobile support assembly is mounted to and configured for movement along a second rail, which is generally parallel to the first rail. The drive shaft extends between and is rotatably mounted to the first mobile support assembly and the second mobile support assembly. The cover carrier mechanism extends between and is rotatably mounted to the first mobile support assembly and the second mobile support assembly. The cover carrier mechanism is configured for selectably deploying a cover carried thereby, with the cover carrier mechanism being configured to respectively roll and unroll the cover relative thereto.

The present invention is an apparatus, system and method for use of an offshore hose loading station comprising multiple modular reel assemblies that may be selectively configured to a frame attached to a ship and or vessel wherein the reel assemblies may be powered by one motor and engaged for rotation by one shaft and provides a jumper shaft for when a module is taken out of line.
